When you first arrive to settle down, one of the things that concerns many people most is income tax in Canada. The system is progressive, made up of a federal portion and a provincial portion, and how your tax obligation is determined depends on your tax residency status.
Understanding the principles correctly from the first year helps you avoid filing errors, while also taking advantage of the tax credits and benefits available to newly settled families. This article explains how the mechanism works, without going into specific figures, which change every year.

Tax residency determines your income tax in Canada
The key thing to understand is that income tax in Canada is tied to “tax residency,” which is not entirely the same as immigration status or citizenship. The federal tax authority (Canada Revenue Agency, or CRA) determines whether you have sufficient residential ties to Canada.
These ties are called “residential ties.” The most important ones include: having a home in Canada, having a spouse or common-law partner in Canada, and having dependent children living here. Secondary ties include bank accounts, a driver’s licence, a provincial health card, and personal belongings.
For most people who have just arrived as permanent residents, you become a tax resident from the very first day you come to live in Canada. This is also the point at which the CRA considers you a “newcomer” for your first tax year.
Tax residents must report worldwide income
Once you are a tax resident, you are required to report your worldwide income for the portion of the year during which you are a resident of Canada. This means that income earned in Vietnam or another country during the period you have already become a resident is, in principle, also subject to reporting.
To avoid double taxation, Canada has tax treaties with many countries to prevent double taxation, along with a foreign tax credit system for taxes already paid abroad. Since this is a complex area, people with significant cross-border income should consult a tax professional in their first year.
How federal tax and provincial tax work
Newcomers are often surprised to learn they pay tax at two levels. The first level is federal tax, which applies uniformly across the country. The second level is the tax of the province or territory where you reside on December 31 of the tax year.
Both levels use a progressive tax schedule: the higher the income, the higher the tax rate on the portion above each threshold. Importantly, only the portion of income that falls within each bracket is taxed at that bracket’s rate, not your entire income jumping to a single rate.
Tax rates and income thresholds for each bracket are adjusted annually. So instead of memorizing figures, you should look up the current tax schedule for your tax year and province from the official source of the Canada Revenue Agency before making your own estimates.
Differences between provinces
Since each province has its own tax schedule, your overall income tax burden in Canada can vary depending on where you settle. Some provinces have lower provincial tax rates, while others are higher but come with different public services.
A special case is Quebec. Quebec residents file a separate provincial tax return with Revenu Québec, alongside their federal return. Other provinces combine the provincial portion into the same return that the CRA processes.
Withholding at source and the Social Insurance Number
If you are a salaried employee, your employer will deduct tax directly from your pay each pay period, known as “withholding at source.” This amount is a provisional estimate; at tax filing time, the system reconciles it to determine whether you owe more or are due a refund.
To work legally and to have the CRA correctly record your income, you need a Social Insurance Number (SIN). This is a mandatory identification number, so you should apply for it as soon as possible after arriving. Keep your SIN secure and only provide it to your employer, bank, or authorized agencies.
In addition to income tax, contributions are also deducted from your pay for mandatory programs such as the Canada Pension Plan (CPP) and Employment Insurance (EI). These are not taxes, but they reduce your take-home pay, so you need to account for them when budgeting for your family.
Filing taxes in the first year: common mistakes newcomers make
The personal income tax return is filed for the previous calendar year, with the usual deadline being April 30. Self-employed individuals and their spouses have a later filing deadline, although any tax owed is still due by April 30.
The first year has a few particular points. On the return, you note the date you became a Canadian resident, because personal tax credits are prorated according to the number of days you were a resident during that year. Reporting this date correctly is very important.
One rule worth noting: if income from Canadian sources makes up 90% or more of your total worldwide income for the year, you may claim the full federal and provincial non-refundable tax credits. If it’s below that threshold, the tax credits will be prorated. Details are provided by the CRA in its guidance for newcomers.
Records and documents to keep
- Income slips issued by your employer (usually a T4 slip) summarizing salary and amounts withheld.
- Income statements from banks and investments (T5 series slips).
- Receipts for deductions or tax credits: childcare, tuition, retirement contributions.
- Documents proving your date of entry and date of becoming a permanent resident, needed to calculate the first-year tax credit proration.
Keep your records for several years in case the CRA requests verification. Many newcomers choose to use CRA-certified tax filing software or hire an accounting service in the first year to get familiar with the process.
Tax credits and family benefits newcomers should know about
Income tax in Canada doesn’t just collect money, it also gives back through benefits tied to filing your return. This is an important reason to file your taxes fully from the very first year, even if your income is still low.
Many family support payments and refunds are assessed based on your tax return. Notably, the federal child benefit for families with young children, and refundable tax credits related to consumption tax. Not filing taxes means missing out on these benefits.
| Contents | Tax (owed) | Benefit/tax credit (may be received) |
|---|---|---|
| Nature | Obligation to the government | Financial support for individuals/families |
| Depends on filing taxes | Mandatory declarations for identification | Must declare to be considered |
| Typical example | Federal + provincial tax | Child benefits, sales tax credits |
The amount and conditions of each benefit change every year and by household income, so you should check the current rates from official sources rather than relying on figures you heard secondhand.
Tax planning alongside family finances
Tax should not be viewed in isolation but as part of the family’s overall financial picture. When you first settle in, opening accounts, organizing spending and understanding recurring obligations helps you stay in control. You can also read more about how to open a bank account and manage finances in Canada to prepare the groundwork.
Beyond that, the tax burden is only part of the cost of living. To get a full picture of how much a family needs each month, you should also read the article on cost of living in Canada. If you bring your whole family, declaring dependents also affects tax credits, so you may want to read the article on bringing your family to Canada.
For people in licensed professions, income — and therefore tax — depends on whether your credentials are recognized. This process relates to the article on credential recognition in Canada which you should look into early.
A few principles to keep in mind
- File your tax return on time every year, even in a low-income year, to keep your eligibility for benefits.
- Update your family information (marriage, having a child, moving province), as this affects tax credits.
- Don’t rely on old figures; check the current tax brackets and thresholds every year.
- When cross-border income gets complicated, seek an expert instead of guessing.
Understanding marginal tax rate and average tax rate
Many newcomers worry because they’ve heard that taxes in Canada are “high”. This worry usually comes from confusing the marginal tax rate with the average tax rate. Distinguishing the two concepts clearly helps you estimate more realistically how much you actually have to pay.
The marginal rate is the tax rate applied to your next dollar of income, i.e., the highest bracket your income reaches. The average rate is your total tax payable divided by your total income, and is usually much lower than the marginal rate.
An illustrative example of the principle, not real figures: if only the portion of income above a certain threshold is taxed at a higher rate, then someone who just crosses that threshold is not taxed at the higher rate on their entire income. So getting a raise that pushes you into a higher bracket never reduces your total after-tax income.
Understanding this helps you feel comfortable taking on extra work or overtime without fear of being “punished by taxes”. It also reminds you that the highest tax rate figure you hear about does not reflect the actual proportion applied to your entire income.
Common deductions and tax deferrals
Canada’s income tax system allows for certain deductions or tax deferrals, if you know about and use them correctly. This is an area many newcomers don’t fully take advantage of in their early years.
An important tool is a tax-advantaged retirement savings account. Contributions to it, within the allowed limit, can reduce your taxable income for the year, and the earnings are tax-deferred until withdrawal. This is both a way to save for retirement and a way to optimize tax.
There is also a type of savings account where earnings inside it are not taxed upon withdrawal, suitable for medium- and long-term goals. Each type of account has its own limits and rules, which are adjusted annually, so you need to check the current limits before contributing.
- Retirement contributions within the limit: reduce taxable income for the contribution year.
- Eligible childcare expenses: may be deductible within prescribed limits.
- Certain moving expenses for work or study: may qualify for deduction.
- Charitable donations to eligible organizations: may generate a tax credit.
The common thread is that all these items require documentation and must fall within legal limits. Keeping full receipts throughout the year will help you file correctly and not miss out on benefits at tax time.
Avoiding double taxation on income from Vietnam
Newcomers often still have assets, accounts or income sources in Vietnam. This is the area most likely to cause confusion, since it involves both reporting obligations and the risk of double taxation.
The principle is that once you become a tax resident, your worldwide income is subject to reporting. However, to avoid the same income being taxed in both countries, Canada applies a foreign tax credit mechanism and tax treaties to avoid double taxation.
In practice, the treatment depends on the type of income: rental income, deposit interest, dividends or business income each have their own rules. Because of the high complexity and significant risk of misreporting, if you have substantial income from Vietnam you should consult a tax expert in your very first year rather than handling it yourself.
Another important note is that some regulations require reporting foreign assets above a certain threshold, even if those assets have not generated income. Failing to meet this reporting obligation can lead to penalties, so you need to check the current requirements to stay compliant.
Summary
Income tax in Canada operates based on tax residency, is levied at both the federal and provincial levels, and is closely tied to annual tax filing. The specific tax amount depends on your income, the province you settle in and your family circumstances. Instead of memorizing figures that can quickly become outdated, master the mechanism and always check current rates from official sources before making financial decisions.

I arrived partway through the year — do I file taxes for the whole year or only the time I was in Canada?
You report worldwide income for the period from the date you became a Canadian resident. This date is recorded on your return and used to prorate personal tax credits for the first year.
Is tax residency the same as permanent resident status?
Not entirely. Tax residency is determined by the CRA based on residential ties such as housing, spouse, and children in Canada. A person can be a permanent resident while their tax residency status is assessed separately based on actual living circumstances.
Why should I file taxes even if my income is very low in the first year?
Many family benefits and refundable tax credits are only assessed if you have filed a return. Not filing means missing out on benefits that newly settled families are entitled to.
What documents do I need to work and pay tax legally?
You need a Social Insurance Number (SIN) so your employer can report your income and the CRA can record it correctly. You should apply for a SIN soon after arrival and keep this number secure.
Is living in Québec different for tax purposes?
Québec residents must file a separate provincial tax return with Revenu Québec, alongside the federal return. Other provinces combine the provincial portion into the same return processed by the CRA.
