When it comes to investing in Canada, accounts generally fall into two broad categories: registered and non-registered. Understanding the difference between the two is an important part of effective financial and tax planning.

When Canadians invest, their money is typically held inside either a registered or a non-registered account. While both types of accounts allow you to buy investments such as stocks, bonds, ETFs, and mutual funds, the difference between them becomes very clear once taxes come into the picture.

In this post, I’ll break down both account types so that even if you’re hearing about them for the first time, you can easily understand the purpose of each account and the benefits it provides.

What Are Registered Accounts?

Registered accounts are savings or investment accounts that are formally registered with the federal government. Because they are registered, they come with specific tax benefits designed to encourage Canadians to save for major life goals such as retirement, education, disability support, and home ownership.

In simple terms, the word registered describes the relationship between the account and the government.

The benefits these accounts provide can show up in different ways, including:

• tax-deductible contributions and tax-deferred growth (for example, an RRSP)

• tax-free growth (for example, a TFSA)

• access to government grants (for example, an RESP or RDSP)

The key idea is that money inside registered accounts is given special tax treatment, which allows it to grow more efficiently over time compared to money held outside these accounts.

Two Key Aspects of Every Registered Account

Every registered account has two defining features:

1. A purpose, (what the account is designed to help you save for), and

2. A benefit (the tax incentive or government support tied to that purpose).

For example:

• The RRSP exists to help Canadians save for retirement.

• The FHSA is meant to help first‑time buyers save for a home.

• The RESP is designed to help families save for their children’s education.

In addition to serving these primary goals, most registered accounts provide a direct tax advantage, that can either reduce taxes today, defer taxes until later, or eliminate tax entirely on certain growth or withdrawals.

To make this clearer, let’s look at the main types of registered accounts in Canada.

Types of Registered Accounts in Canada

1. Tax-Free Savings Account (TFSA)

Purpose: Allows Canadians to save and invest using annual contribution room. Unlike a typical savings account, funds can be used to buy investments such as stocks, bonds, ETFs, and mutual funds.

Benefit:

• All investment growth is tax‑free, regardless of performance.

• Withdrawals are tax‑free and can be made at any time.

• Any amount withdrawn is added back to your contribution room the following year.

• Unused room rolls forward indefinitely.

2. Registered Retirement Savings Plan (RRSP)

Purpose: Helps Canadians save for retirement. Contributions can be invested in a wide range of assets.

Benefit:

• Contributions are tax‑deductible, reducing your taxable income.

• Investment growth is tax‑deferred until withdrawn

3. Registered Retirement Income Fund (RRIF)

Purpose: Used at retirement by converting RRSP savings into a withdrawal plan.

Benefit:

• Investments continue to grow tax‑deferred.

• Mandatory minimum withdrawals apply each year.

4. First Home Savings Account (FHSA)

Purpose: Designed for first‑time homebuyers to save for a down payment. Annual contributions are capped at $8,000, with a lifetime maximum of $40,000.

Benefit:

• Contributions are tax‑deductible (like an RRSP).

• Investment growth is tax‑deferred.

• Qualifying withdrawals for a first home are tax‑free (like a TFSA).

5. Registered Education Savings Plan (RESP)

Purpose: Helps families save for a child’s post‑secondary education.

Benefit:

• Investment growth is tax‑deferred.

• Contributions may receive government incentives such as the Canada Education Savings Grant (CESG).

6. Registered Disability Savings Plan (RDSP)

Purpose: Provides long‑term savings support for individuals living with disabilities.

Benefit:

• Investments grow tax‑deferred.

• Eligible contributions may receive the Canada Disability Savings Grant and in some cases the Disability Savings Bond.

There are also other registered plans, such as LIRAs, LIFs, DPSPs, and PRPPs, which are typically tied to workplace pensions or specific employment situations.

What Are Non-Registered Accounts?

Now that the registered accounts and their benefits are clear, it becomes easier to define a non‑registered account.

A non‑registered account is simply the opposite of a registered account. They are standard brokerage or investment accounts that do not come with government-provided tax benefits. This means that any income earned in these accounts, such as interest, dividends, or capital gains, is generally taxable in the year it is earned.

However, non‑registered accounts are still extremely useful, especially once you’ve maximized your registered accounts or need full flexibility with your money.

Bottom Line

Registered accounts, when used properly, can be powerful wealth‑building tools. Whether through:

• Tax‑free growth (TFSA)

• Tax deductions (RRSP, FHSA)

• Tax‑deferred compounding (RRSP, RRIF, RESP, RDSP)

• Government grants (RESP, RDSP)

…these accounts help Canadians save more efficiently and keep more of their investment growth.

Non-registered accounts still play an important role, especially when flexibility is needed, but they don’t offer the same tax benefits.

Understanding the difference between these two types of accounts is a game changer and can help you make better long-term financial decisions.

Quick note: This is a longer read than my usual posts. I tried shortening it, but a lot of the important details didn’t survive the cut. Bear with me on this one, it’s worth it.

A lot of Canadians don’t really know how to read a tax return, and honestly, that’s not surprising. Reading a tax return isn’t exactly fun (unless you’re like me and genuinely enjoy looking at numbers). It’s not a book on your favourite topic. It’s just pages of words, codes, and numbers that all lead to one final result, either a refund or a balance owing.

Over the years, I’ve had people ask me to look over their tax return before they file it, or before they tell their tax preparer to go ahead and submit it. Most of the time, they’re not trying to double-check the math. They just want to understand what they’re looking at.

A tax return is one of the most important financial documents you’ll deal with. If something goes wrong on it, even something small, it can create problems that take time and effort to fix. The goal of this series is simple: to make tax returns feel less confusing. So the next time you see one, it doesn’t feel like a mystery.

The T1 Personal Income Tax Return

This first part focuses on the T1 Personal Income and Benefit Tax Return, which is the main tax return most individuals file.

What Is a T1?

The T1 is the form you use to report your income, claim deductions and credits, and figure out whether you owe tax or get a refund.

Breaking the name down helps:

• Personal: it’s about you as an individual

• Income: it reports what you earned during the year

• Benefit: it helps determine what credits or benefits you qualify for

• Tax: it pulls everything together to arrive at the final result

When you look at a T1, it shows:

• how much income you earned

• what expenses or deductions reduced that income

• what credits reduced the tax you had to pay

• how much tax was calculated

• how much tax was already paid during the year

• whether you owe money or are getting money back

How the T1 Is Laid Out

The T1 is made up of eight pages, grouped into six steps. Instead of seeing it as one long form, it helps to think of it as a process. Each step builds on the one before it.

I’ll walk through those steps one by one.

Step 1: Your Personal Information (Pages 1-2 on the T1)

This is the part most people ignore because there are no numbers on it. But it’s more important than it looks.

On these pages, you’ll see things like:

• your name and address

• your SIN and date of birth

• your marital status

• your province of residence as at December 31 of the tax year

• basic information about your spouse or partner, if you have one

Page 2 also includes other questions, such as Indigenous status, foreign property, and consent options (for Elections Canada and the organ and tissue donor registry).

Even though there are no figures here, mistakes can still cause real problems. For example:

• if your marital status is wrong, you could miss out on credits tied to your partner’s income

• if you’re Indigenous and that section isn’t completed properly, you could end up paying tax on income you didn’t need to pay tax on (such as income earned on a reserve)

• if the wrong province is selected, your tax could be calculated incorrectly, which often leads to reassessments later (for example, Ontario tax instead of Alberta)

It may not look important, but this section sets the foundation for everything else on the return.

Step 2: Total Income (Page 3)

This is where the numbers start.

Total income represents all the types of income a Canadian resident can earn in a year. Each type of income has its own line number. There are many of them, so I’ll focus on a few common ones.

• Line 10100: Employment income. This is the total of Box 14 from all your T4 slips. You may recognize this number from when you first set up your CRA account.

• Line 10400: Other employment income. This includes income that may not appear on a T4. Amounts reported on a T4A, often issued to independent contractors, are also included here.

• Lines 12000 and 12010: Dividends received from taxable Canadian corporations.

• Lines 12599 and 12600: Rental income.

• Line 12700: Capital gains, such as gains from selling shares or property, or exercising stock options.

• Lines 12900 and 12905: Income from RRSPs and FHSAs, respectively.

• Line 13000: Other income not captured elsewhere, such as lump-sum payments or certain bonuses.

• Lines 13499 to 14300: Self-employment income reported on Form T2125.

All income amounts are added together and reported on Line 15000, which represents total income.

Step 3: Net Income (Page 4)

This is where deductions come in.

Deductions are expenses that reduce your income before tax is calculated. Not all expenses qualify. Generally, the CRA allows expenses that were necessary to earn the income reported in Step 2.

Common deductions include:

• childcare expenses

• union or professional dues

• employment expenses, such as work-from-home expenses

• moving expenses

• investment expenses

• business investment losses

The CRA also allows deductions for contributions to registered plans, such as RRSPs, RPPs, and FHSAs.

Once these deductions are applied, you arrive at net income, which is reported on Line 23600.

Step 4: Taxable Income (Page 5)

Taxable income is the amount tax rates are applied to.

Starting from net income, a few additional deductions are subtracted to arrive at taxable income. These deductions are less common, but it helps to know they exist. Some examples are:

• deductions for Canadian Armed Forces personnel and police officers

• non-capital and net capital losses from other years

• the northern residents deduction, which applies to people living in prescribed northern or remote areas

After these adjustments, you arrive at taxable income, which is the number used to calculate tax.

Step 5: Federal Tax (Pages 5–7)

This is where things start to feel complicated for most people. From experience, many people don’t spend much time here because it’s full of calculations that genuinely look confusing at first glance.

I won’t try to teach you how to calculate tax here, but I will show you how this section is laid out, so you understand what you’re looking at.

The federal tax calculation is broken into three parts:

• Part A: Federal tax on taxable income

• Part B: Federal non-refundable tax credits

• Part C: Net federal tax

Let’s walk through each one.

Part A: Federal Tax on Taxable Income

This is where tax rates are applied to your taxable income.

The amount of tax calculated here depends on which tax brackets your taxable income (from Step 4) falls into. Canada uses a progressive tax system, which means different portions of your income are taxed at different rates.

Simple example: If your taxable income is $60,000, not all of it is taxed at one rate. The first portion is taxed at a lower rate, the next portion at a higher rate, and so on. When all of that is added together, you get your total federal tax before credits.

That total is what shows up in Part A.

Part B: Federal Non-Refundable Tax Credits

Next come non-refundable tax credits.

A 1non-refundable tax credit reduces the amount of tax you owe, but it cannot reduce your tax below zero or result in a refund.

Here’s what that means in real terms:

If your federal tax from Part A is $5,000, and your non-refundable tax credits add up to $6,000, your tax payable becomes $0. You do not get the extra $1,000 as a refund.

Examples of non-refundable tax credits include:

• the home buyers’ amount

• adoption expenses

• the disability amount (for yourself or transferred from a dependant)

• interest paid on student loans

If you’re eligible for any of these, they appear here and are used to reduce the tax calculated in Part A.

Part C: Net Federal Tax

This is where everything is pulled together.

The starting point here is the figure after non-refundable credits in Part B. From there:

• additional taxes, such as Tax on Split Income (TOSI), may be added, and

• certain credits, like the dividend tax credit from dividends received from taxable Canadian corporations, are subtracted

After these adjustments, you arrive at your net federal tax.

This is your final federal tax figure before it’s compared to what you’ve already paid.

Step 6: Refund or Balance Owing (Pages 7 & 8)

This is the part most people go straight to.

Here, the return compares how much tax you were supposed to pay with how much tax was already taken during the year, usually from your paycheques.

What many people don’t realize is that this comparison isn’t based only on income tax deducted. Other amounts also come into play, including:

• CPP or QPP contributions

• EI contributions

If you’ve overpaid any of these, they’re factored in here.

If the total amount you’ve already paid is more than what you owe, you get a refund. If it’s less, you owe the difference.

Takeaway

You don’t need to understand every single line on your tax return. But understanding how it flows makes a big difference.

My hope is that this post has helped remove some of the mystery around the T1 return, and that the next time you see one, you’ll take a more meaningful look at it.

You just might find it a little less intimidating than before. Maybe even a bit interesting.

One of the most common words on people’s minds at the start of a new year is tax. For some, it’s eagerly anticipated. For others, it’s dreaded. Tax season rarely feels new, but every year there are a few updates that are important to be aware of, especially to avoid being caught by surprise.

Here’s what to expect before filing, during filing, and after you file.

When the 2026 Tax Season Officially Begins

February 23, 2026 - This is the official opening date for both NETFILE (for individuals) and EFILE (used by tax professionals). Returns can be prepared before this date, but they cannot be successfully filed until then.

Key deadlines to keep in mind

• March 2, 2026
  Deadline to contribute to your RRSP for the 2025 tax year. Contributions made between March 1, 2025, and March 2, 2026, can be deducted during the 2026 tax season.

• April 30, 2026
  Deadline to pay any tax owing for all individuals, including self-employed individuals.

• June 15, 2026
  Filing deadline for self-employed individuals. Note that any balance owing is still due by April 30, 2026.

What to Expect With Tax Slips This Year

Last year, missing and late slips caused real frustration for many taxpayers. The Auto-fill My Return (AFR) feature used by tax preparers was unable to pull slips into tax software because they were not yet available on taxpayers’ CRA profiles. As a result, many returns could not be filed early, and when they were eventually filed, assessments and refunds were often delayed.

In addition, some returns that were filed using available information were later reassessed because they were submitted with incomplete slip data.

The CRA has indicated that improvements have been made for the 2026 tax season, including earlier access to slips through the AFR feature. That said, delays can still occur, particularly where employers or financial institutions submit information late.

For some taxpayers, especially those with multiple income sources or several employers during the year, filing too early may not always be the best approach. In such cases, waiting until all slips are available can help reduce the risk of reassessments.

How to Prepare for the 2026 Tax Season

As with most things, failing to prepare often leads to disappointing outcomes. Preparing for tax season does not need to be overwhelming. It simply means understanding what needs to be done and doing it properly, which significantly reduces surprises.

Before filing opens, the following steps can help:

• Confirm your personal information with the CRA.
  If you log in only once a year, or rarely at all, access can be challenging due to the CRA’s security and verification processes. Starting early helps avoid last-minute delays.

• Check prior-year assessments.
  Ensure your previous returns were successfully assessed and that no reassessments or requests for information are still outstanding. Ideally, this should be done well before tax season, but it is still worthwhile if it hasn’t been addressed yet.

• Gather your documents.
  This includes income slips (T4, T4A, T5, etc.) and expense receipts such as donations or eligible home expenses. While income slips may not yet be available, as employers typically have until late February to issue them, you can still organize documents you already have control over.

• Review whether anything needs to change from prior years.
  If you filed your return yourself and felt uncertain about the outcome, this may be a good time to consider professional assistance. If you plan to file on your own again, take time to understand what should be done differently.

Many tax surprises do not happen because filing is complex. They happen because key details were overlooked.

After You File: What Actually Happens

Refund Timelines

Once a return is filed, an Express Notice of Assessment is often issued almost immediately. The official Notice of Assessment is typically sent once the return is fully processed, with refunds generally issued within two weeks of filing.

However, some returns are selected for pre-assessment review. This means the CRA requires additional information before completing the assessment. When this happens, refund timelines can extend from weeks to several months.

Common reasons for pre-assessment reviews include:

• late or amended slips

• CRA matching programs

• benefit recalculations

• verification reviews

These situations can be frustrating, especially if plans were made around an expected refund. This is another reason why being prepared and filing accurately matters.

Post-Assessment Reviews

A post-assessment review occurs after a Notice of Assessment has been issued and, in some cases, after a refund has already been received. These reviews often happen weeks or months after the April 30 deadline.

This process is normal and does not imply wrongdoing. The CRA conducts post-assessment reviews each year on selected returns.

It is important to respond promptly to any review letter received. Delayed responses can result in unnecessary penalties or interest on the item under review.

The Value of Knowing What to Expect

The real benefit of preparing for tax season is not avoiding mistakes or filing early. It is understanding the process well enough to know what is normal and what is not.

When you know the timelines, the filing windows, and what happens after you submit a return, tax season becomes predictable. That predictability allows you to plan better, make informed decisions, and approach filing with confidence rather than uncertainty.

Preparation does not change the rules. It changes how you experience them.

Many newcomers make mistakes in their first few tax filings and do not even realize that they have done so. This is often because, despite the abundance of information available, there is still very little that clearly points out the specific areas newcomers need to be wary of.

As an immigrant tax professional who handles the taxes of several other immigrants, I have first-hand experience with these issues.

Below are some of the most common areas where this gap shows up.

1. Assuming Filing Taxes Is Optional If Income Is Low

Many newcomers believe that if they earned little or no income, filing a tax return is optional. In some cases, where no income was earned, filing may not be legally required. However, choosing not to file often has consequences.

In Canada, filing a tax return is how eligibility for income-tested benefits is determined. Without a return on file, benefits such as the GST/HST credit and other federal and provincial programs cannot be assessed or paid.

This is one of the most common reasons newcomers miss out on benefits in their early years.

2. Not Understanding Tax Residency Rules

Tax residency in Canada is not based solely on citizenship or immigration status. It is determined by the strength of your residential ties to Canada.

Some of the factors that may be considered include:

• where you have a home or place of residence

• whether your spouse or dependants live in Canada

• where you work or carry on employment

• where you maintain personal property, bank accounts, or provincial health coverage

• how long and how consistently you are physically present in Canada

Many newcomers assume they are not tax residents if they arrived late in the year or stayed only briefly. In reality, even a short period of residency, combined with sufficient ties, can result in tax residency for part of the year.

For example, a person who spends only a few months in Canada (less than 183 days), but has a residential home in Canada, a spouse or dependants who are tax residents, or maintains bank accounts or property in Canada, may still be considered a resident for tax purposes, despite not meeting the 183-day rule.

As a matter of fact, determining tax residency is one of the most complex areas in Canadian tax, and one that has seen several cases taken to the tax courts.

Misunderstanding these rules can lead to missed filings, delayed benefits, or incorrect reporting, and the consequences can be significant. It is therefore very important for newcomers to be properly informed on this matter.

3. Contributing to an RRSP Without Having RRSP Room

This is a very common and costly mistake.

RRSP contribution room is not automatic. Contribution room is earned only based on income assessed on a previous year’s Canadian tax return. As a result, a newcomer to Canada who has not previously been a tax resident generally does not have RRSP contribution room in their first year.

Contributing to an RRSP without available room results in an overcontribution. When an 1overcontribution occurs, it must be corrected by withdrawing the excess amount and submitting a completed Form T1-OVP to the CRA.

If the issue is not corrected promptly, a penalty of 1% per month applies to the excess contribution until the situation is resolved. The administrative process can take time, during which penalties may continue to accumulate.

4. Not Applying for GST/HST Credits and Canada Carbon Rebates (CCR) Using Form RC151

For newcomers who arrive in Canada during the year, the GST/HST credit and CCR is not automatically paid unless eligibility is established through filing a tax return. Since an income tax return is not due until April 30 of the following year, newcomers often face the challenge of not receiving any benefits during their year of arrival.

To address this, the CRA introduced Form RC151, which allows newcomers to apply for the GST/HST credit and the Canada Carbon Rebate before filing their first tax return.

Without submitting this form, eligible newcomers may not receive GST/HST credits during the year they arrive, even though they otherwise qualify. Instead, they may have to wait until their first tax return is filed and assessed before receiving the benefits retroactively.

5. Refusing to Consult Professionals

Many newcomers assume they can figure things out on their own, even when they find themselves in situations that require professional guidance.

Certain requests or correspondence from the CRA require the input of someone who understands the process, or who has dealt with similar situations before. Choosing not to seek help often proves costly and can significantly prolong the resolution of issues.

Closing Thought

Most tax issues newcomers face are not the result of errors on a tax return. They arise from assumptions made where clear explanations were missing, or from simple lack of awareness.

While the government, through the CRA and other agencies, provides resources to guide taxpayers, gaps still exist, and these gaps often prove costly for newcomers. Understanding where these gaps are, and how to navigate the system confidently, can be key to avoiding mistakes that were never intended in the first place.

Most people think of taxes as a task. Something you deal with once a year, submit, and try not to think about again until the next filing season. That reaction is understandable. Taxes are not designed to feel friendly, especially for those who are not in the industry, do not enjoy numbers, or are navigating the system for the first time.

For many immigrants, that discomfort is even stronger. You arrive in a new country and are expected to understand a tax system that may be very different from what you were used to back home, often without much guidance.

But whether we like it or not, taxes sit quietly at the center of our financial lives. They show up in our paycheques, our benefits, our savings decisions, and sometimes in moments when nothing seems to have changed, yet the numbers suddenly look different.

Understanding taxes, even at a basic level, is less about expertise and more about peace of mind.

Why Tax Planning Matters More Than People Admit

Tax planning is one of the most important aspects of personal finance that many people overlook. Taxes have a way of quietly shaping financial outcomes, and getting them right or wrong can affect several years of your financial journey.

One point I often emphasize, especially to newcomers, is that tax planning for the next year starts at the beginning of the current year, not during tax season. Refunds, benefits, and balances owing are usually the result of decisions made throughout the year.

For example:

• Contributing to a TFSA early in the year allows more time for tax-free growth.

• Making RRSP or FHSA contributions creates deductions that reduce taxable income.

• For business owners, failing to plan early between salary and dividends can affect personal cash flow, CPP contributions, and overall tax efficiency.

Once the year has passed, many of these opportunities are no longer available. Time spent ignoring your tax situation is often time that cannot be recovered.

Uncertainty Is the Real Source of Tax Stress

When people say they are stressed about taxes, they are rarely talking about tax rates or rules. What they usually mean is that they do not know what to expect.

Questions like:

• “Am I required to report this income?”

• “Can I deduct this expense?”

• “Why is my refund smaller?”

• “Why do I owe tax this year?”

• “What does this CRA letter mean?”

These questions are common, particularly for immigrants still learning how the Canadian system works. Most of them can be addressed with basic awareness and planning.

Understanding how the system works does not guarantee a perfect outcome every year, but it replaces fear with explanation. That alone makes tax season feel more manageable.

Separating Emotion From Outcome

Tax results can feel personal. A balance owing may feel like a mistake. A smaller refund may feel disappointing. A letter from the CRA can trigger anxiety, especially if you are unfamiliar with how the CRA communicates.

In many cases, nothing went wrong. What changed was timing, income mix, or how deductions were applied during the year.

Understanding that difference helps you respond instead of react. You begin asking why something happened rather than assuming the worst.

Taxes Influence More Daily Decisions Than You Think

Taxes quietly affect many everyday decisions. How much of your salary you can plan around. Why a bonus feels smaller than expected. Why deductions stop partway through the year. Why two people with similar income can end up with different tax outcomes.

When you understand the basics, these outcomes stop feeling random. You start to recognize patterns and anticipate results, even if roughly. That awareness makes financial decisions feel less reactive and more intentional.

You Do Not Need to Know Everything

Understanding your taxes does not mean memorizing tax brackets or reading legislation. It means knowing enough to recognize what is normal, what deserves attention, and when to consult a tax professional.

For most people, that level of understanding is enough to reduce stress, avoid surprises, and ask better questions. You are not trying to become a tax expert. You are trying to feel more comfortable with something that affects you every year.

A Calmer Way to Think About Taxes

Taxes are not a once-a-year event. They are the result of decisions and deductions that happen quietly throughout the year.

When you see them that way, tax season becomes less of a reckoning and more of a review. Not something to fear, but something to understand.

Understanding your taxes reduces anxiety, improves clarity, and gives you a stronger sense of control over your financial life. That is what makes it a form of financial self-care.

People are often confused about why a change in employment during the year can affect their tax situation. For many, this confusion arises because all income earned was employment income, with taxes deducted at source. On the surface, it feels like there should be no additional tax to pay.

In practice, changing jobs may or may not affect your taxes. In many cases, the deductions remain accurate and nothing changes at filing. In other cases, differences arise because each employer calculates deductions independently, using only the information available to them at the time.

These differences are usually small, but they can result in a balance owing or a refund once all income is combined and reconciled on the tax return. Understanding how this happens helps explain why a job change can sometimes affect your tax outcome, even when nothing else in your situation has changed.

1. Your New Employer Starts Fresh

When you change jobs, your new employer does not know:

• how much income you earned earlier in the year

• how much tax has already been deducted

• what tax credits have already been applied

So they simply start deducting taxes based on the information available to them, which is:

• your salary with the new employer

• the TD1 form you complete when you start

From their perspective, this is the only information they are allowed to use.

2. How Your Pay Is Calculated

Income tax is deducted based on the tax bracket your salary appears to fall into. In addition to income tax, other amounts such as CPP and EI are deducted based on your earnings.

After these deductions, federal and provincial tax credits are applied before arriving at your take-home pay.

There is also an annual limit to how much CPP and EI you are required to contribute. Once those limits are reached, the deductions stop for the rest of the year.

However, when you change employers mid-year, both employers may deduct CPP and EI because neither knows what the other has already deducted. This can result in over-contributions, which are later reconciled when you file your tax return.

3. Why the TD1 Form Matters

This is where the TD1 form becomes especially important.

The TD1 (Personal Tax Credits Return) is used to determine how much federal and provincial income tax should be withheld from your pay. It accounts for personal tax credits that reduce the amount of tax deducted, such as:

• the basic personal amount

• spousal credits

• caregiving credits

• tuition credits

Every employee is required to complete a TD1 when starting a new job, and they can update it during the year if their situation changes.

When someone changes jobs during the year, a common issue arises. Certain credits, especially the basic personal amount, may be applied more than once. In effect, the same annual credits are spread across two employers.

4. How Two Employers Can Lead to a Balance Owing

When two employers both apply the same tax credits, it can result in less tax being deducted overall. This often shows up as a slightly higher take-home pay during the year, but it can lead to a balance owing once everything is reconciled at tax time.

Here’s a simple example.

Assume Tunde, a Nigerian newcomer to Canada, worked for two employers in the same year.

• From January to June, Tunde worked for Employer A and earned $40,000.

• From July to December, he switched jobs and earned another $40,000 with Employer B.

His total income for the year was $80,000.

At both jobs, Tunde completed a TD1 form claiming the basic personal amount, which for simplicity we’ll assume shelters $15,000 of income from tax.

Each employer, acting independently, applied this credit when calculating his deductions.

• Employer A calculated tax as if Tunde would earn only $40,000 for the year and applied the $15,000 credit.

• Employer B did the same.

In effect, $30,000 of Tunde’s income was treated as tax-free during the year, even though only $15,000 should have been.

Because of this, less tax was deducted from his pay cheques across the year, and his take-home pay was slightly higher than it should have been. Nothing looked wrong at the time.

When Tunde filed his tax return, however, the CRA combined his income from both employers and recalculated the tax owing based on the correct single set of credits. The result was a balance owing, not because he earned extra income or made a mistake, but because too little tax had been withheld during the year.

This is one of the most common reasons people owe tax after changing jobs, even when all their income came from employment and taxes were deducted at source.

Conclusion

Changing jobs during a year does not automatically affect your taxes. In many cases, the correct amount of tax is still deducted, and no adjustment is required at filing.

However, when income is split across employers, deductions are calculated in isolation. This can lead to situations where tax credits are applied more than once, or where CPP and EI contributions are duplicated. These differences are only reconciled when all income is combined on the tax return.

Understanding how employers calculate deductions, and how credits are applied across multiple jobs, helps explain why a balance owing can arise even when all income is employment income and taxes were withheld at source.

Filing a tax return in a new country can feel like opening a door without knowing what’s on the other side. As a newcomer myself, I remember how unfamiliar everything felt, not because the rules were complicated or because I didn’t understand what I was doing, but because the entire process was so different from what I was used to.

In fact, growing up and living in Nigeria almost meant you had never filed a tax return. So arriving in Canada and suddenly being expected to interact with a structured, connected tax system was a major shift.

Looking back, here are the things that surprised me the most.

1. Filing Taxes Is Technically Optional, Until It Isn’t

Contrary to what you may have heard, the CRA does not mandate every Canadian to file a tax return every single year. What they do, however, is strongly advise you to, because not filing can mean missing out on benefits you are entitled to.

As a permanent resident of Canada, you may be eligible for benefits such as the GST/HST credit, Climate Action Incentive (carbon rebate), and the Canada Child Benefit, depending on your situation. However, access to these benefits depends on one thing: having an active file with the CRA.

Without filing, the CRA does not recognize your eligibility and will simply hold on to those benefits until you do.

That said, let me be very clear.

If you earn income in a year, filing your tax return is mandatory. Failing to do so can result in penalties, interest, and in more serious cases, fines or legal consequences. You will also almost certainly lose access to benefits like the GST/HST credit, Climate Action payments, and the Canada Child Benefit.

2. The Refund

If you were born and raised in Canada, you may be wondering why receiving a refund surprised me.

In simple terms, the concept of a tax refund was foreign to me, not because I didn’t understand what it meant (I am a tax professional, after all), but because my home country did not have a robust system where taxpayers could accurately file returns and receive benefits owed to them, at least at the time of writing. I suspect this experience is shared by many immigrants reading this.

Having worked for only two months in the year, I didn’t expect a refund, especially since my taxes had already been withheld by my employer. To my surprise, the refund I received was exactly equal to the tax that had been deducted from my pay.

I later understood why. My total income for the year was below the Basic Personal Amount for 2022, meaning I was effectively considered a low-income earner for tax purposes.

So yes, depending on your situation, you can receive a refund even if taxes were already deducted from your pay.

3. You Can Be a Tax Resident Even If You Arrived Late in the Year

Many newcomers assume they don’t need to file taxes because they arrived late in the year. This is wrong.

The CRA uses specific rules to determine tax residency, and in some cases, being in Canada for even a single day in a calendar year can put you in that position.

As mentioned earlier, not filing when required can lead to temporary or permanent loss of benefits. That is why it is important to understand these rules, or at the very least, seek advice from a tax professional.

4. You Can Do It Yourself

Yes, you can absolutely file your taxes yourself.

Through a system called NETFILE, the CRA authorizes various tax software providers that allow individuals to prepare and file their returns by answering a series of guided questions. This can often be done at little or no cost.

That said, I always tell people this. If your tax situation is even slightly complicated, or if you are unsure of what you are doing, consulting a tax professional is worth it.

It is far better to spend a few dollars getting it right than to spend much more later correcting mistakes caused by confusion or misinformation.

5. Filing Taxes Means Access to the Canadian System

This might have been the biggest surprise of all.

Filing tax returns is not just about compliance. It is your entry point into Canada’s financial and benefits system. It establishes your income, your residency, your eligibility for government programs, and your household status.

In fact, without a history of tax compliance, you may find it difficult to rent a home, access certain banking services, or qualify for credit facilities.

In many ways, filing taxes is a core part of building your life in Canada.

A Simple Lesson

Filing my first tax return didn’t just teach me about taxes. It taught me how the system works and gave me a sense of responsibility and belonging.

And that made every tax season after that feel a little less intimidating.

A lot of people approach tax season with excitement for no reason other than the expectation of a refund, often a hefty one. For some, they feel they have worked all year toward it, so why not expect something back? For others, the expectation exists simply because they believe that filing a tax return should naturally result in a refund.

Admit it. A tax refund feels good because it feels like a reward. For some people, it even feels like proof that they “did their taxes right.”

For many immigrants, this expectation is shaped by something else entirely. In some countries, tax refunds are rare, unclear, or simply not part of the system at all. So when you arrive in Canada and hear people talk about refunds every year, it starts to feel like a normal outcome, almost like an entitlement.

A refund is not a bonus. If it were, it would be taxed, as it would qualify as income. It is also not a “benefit” in the traditional sense of the word. Benefits are payments designed to support individuals and families in specific situations (for example, low-income earners or people living with disabilities).

Think of a refund as a reconciliation of your income and the tax paid to the CRA. Where the latter is greater than the former, the difference is returned to you. It is quite literally your own money being paid back to you.

What a Refund Actually Is

A tax refund simply means you paid more tax during the year than you ultimately owed, and the CRA is returning the excess.

An overpayment can happen for several reasons, including:

• your employer withheld more tax than necessary (either in error or based on information available at the time)

• you worked only part of the year, meaning your income fell below the basic personal amount or other thresholds used in payroll calculations

• you qualified for credits or deductions that were not reflected during payroll (for example, tuition credits or childcare expenses)

• your income changed mid-year, such as switching jobs, receiving a bonus, or earning income for only part of the year

In most cases, a refund is not the result of a single decision, but of timing and incomplete information during the year. Payroll systems are designed to estimate, not to be perfect. The tax return is where everything is brought together and corrected.

How Benefits Can Lead to a Refund

Some refunds are also driven by refundable tax credits. These are credits that can result in a refund even if little or no tax was paid during the year.

Examples include:

• Canada Workers Benefit (CWB), a refundable tax credit for working individuals earning a modest income

• Canada Training Credit (CTC), designed to help Canadians offset the cost of eligible training fees

• Medical Expense Tax Credit, which supports individuals who incur qualifying medical expenses during the year

When these credits are correctly claimed on a tax return, they can push your total tax paid above your final tax liability, resulting in a refund.

This is one reason filing a tax return is important even in years when income is low. Many refundable credits are only accessed through filing, and without a return, the CRA has no way to assess eligibility or issue payment.

Why a Bigger Refund Isn’t Necessarily Better

This is the part many people find surprising. A larger refund often means you had less money available to you during the year than you could have. Your paycheques were smaller than necessary, and the excess remained with the government until you filed your return.

Some people prefer this and see it as a form of forced savings. Others would rather have access to their money throughout the year. Neither approach is wrong, but it is important to understand what is actually happening.

Many credits that reduce tax can be reflected during the year through the TD1 form. While this does not account for every situation, particularly where total income differs from employment income, it can reduce over-withholding. In cases where employment income represents most or all of a person’s income, this allows tax credits to be enjoyed in real time rather than months later at filing.

A large refund may feel satisfying, but it often reflects timing rather than tax efficiency. Understanding this helps shift the focus from the size of the refund to whether tax deductions during the year were reasonably accurate.

A More Useful Way to Think About Refunds

Instead of asking, “How big is my refund?” a better question is, “Did I pay roughly the right amount of tax during the year?”

A small refund or a small balance owing usually means deductions were fairly accurate. Large swings in either direction often signal changes in income, credits, or deductions that could be adjusted going forward.

When you understand this, refunds stop feeling mysterious and owing stops feeling personal. There is no such thing as a “magic refund.” There is simply a system designed to estimate during the year and reconcile at the end.
