What Is the 90% Rule for Newcomers to Canada?
The 90% rule is a Canadian tax rule that affects how certain federal non-refundable tax credits are calculated for people who become Canadian tax residents partway through a tax year.
When you move to Canada and become a tax resident, you may be eligible for federal tax credits. However, the Canada Revenue Agency (CRA) considers your income from the period before you became a Canadian tax resident when deciding whether you can claim certain credits in full.
Under this rule, you may qualify for the full amount of eligible federal non-refundable tax credits if at least 90% of your net worldwide income during your non-resident period came from Canadian sources.
If less than 90% of your net worldwide income came from Canadian sources, your eligible credits may be reduced based on the number of days you were a Canadian tax resident during that year.
For example, if you earned income outside Canada before becoming a Canadian tax resident, that income may be included when calculating the 90% threshold.
Why Does the 90% Rule Matter?
Many newcomers arrive in Canada during the middle of the year. Before moving, they may have earned income in another country, while after arriving, they may start earning income in Canada.
The CRA uses the 90% rule to determine whether certain federal tax credits should be available in full or adjusted for the part of the year during which the person was a Canadian tax resident.
This matters because non-refundable tax credits can reduce the amount of federal income tax you owe. If you do not meet the 90% threshold, you may not be able to claim the full amount of certain credits for that tax year.
It is also important to understand that becoming a Canadian tax resident is not always the same as receiving permanent resident status or arriving in Canada. Your residential ties and individual circumstances help determine your tax residency.
How Does the 90% Rule Work?
The CRA looks at your income during the period when you were not a Canadian tax resident in the year you moved to Canada. You need to compare your Canadian-source income with your net worldwide income for that period.
Here is how the process generally works.
1. Identify Your Canadian Tax Residency Date
First, determine the date you became a Canadian tax resident.
This date is based on your residential ties and circumstances, rather than your immigration status alone. It is important because it separates your non-resident period from your Canadian tax-resident period.
2. Calculate Your Canadian-Source Income
Next, work out how much net income you earned from Canadian sources during the period before you became a Canadian tax resident.
This is the Canadian-source portion of your income that will be used in the 90% calculation.
3. Calculate Your Net Worldwide Income
You must also calculate your net worldwide income for the same non-resident period.
This includes income from Canadian and foreign sources. Income earned outside Canada before you became a tax resident can therefore affect whether you meet the 90% threshold.
4. Check Whether You Meet the 90% Threshold
Compare your Canadian-source income with your net worldwide income.
The calculation can be expressed as:
Canadian-source net income ÷ Net worldwide income × 100
If the result is at least 90%, you may qualify to claim the full amount of eligible federal non-refundable tax credits, subject to the applicable rules.
If the result is below 90%, your eligible credits may be prorated according to the time you were a Canadian tax resident.
5. Report Your Pre-Arrival Income
When filing your Canadian tax return, you may need to provide details of your net worldwide income for the period before you became a Canadian tax resident.
This information helps the CRA determine whether you meet the 90% rule. If you do not provide the required details, the CRA may not allow you to claim the full amount of eligible credits.
6. Check Which Tax Credits You Can Claim
The 90% rule applies to certain federal non-refundable tax credits. These may include credits such as:
- Basic Personal Amount
- Spouse or Common-Law Partner Amount
- Eligible Dependant Amount
- Age Amount
- Certain caregiver-related amounts
Your eligibility depends on your individual circumstances and the requirements for each credit. Other tax credits may follow separate rules.
Examples of the 90% Rule
A few examples can make the 90% rule easier to understand.
Example 1: Newcomer Meets the 90% Rule
Suppose you earned the following income before becoming a Canadian tax resident:
- Canadian-source income: CAD $18,000
- Foreign-source income: CAD $2,000
- Net worldwide income: CAD $20,000
Your Canadian-source income represents 90% of your net worldwide income.
In this situation, you meet the 90% threshold and may qualify for the full amount of eligible federal non-refundable tax credits.
Example 2: Newcomer Does Not Meet the 90% Rule
Now consider a newcomer with the following income:
- Canadian-source income: CAD $16,000
- Foreign-source income: CAD $4,000
- Net worldwide income: CAD $20,000
Here, Canadian-source income represents 80% of net worldwide income.
Since the percentage is below 90%, the newcomer does not meet the threshold. The applicable federal non-refundable tax credits may therefore be prorated.
Example 3: Newcomer Had No Income Before Arriving in Canada
A newcomer may have had no income during the period before becoming a Canadian tax resident.
However, having zero income does not automatically mean that the person meets the 90% rule. Under the CRA guidance applicable to 2024 and later tax years, a newcomer with no worldwide income during the non-resident period does not automatically qualify for the full credits under this test.
The applicable credits may instead be prorated.
90% Rule vs. Tax Credit Proration
The 90% rule determines whether certain federal non-refundable tax credits can be claimed in full or need to be adjusted.
Here is a simple comparison:
| Situation | How eligible credits are treated |
| At least 90% of net worldwide income came from Canadian sources | You may claim the full eligible federal non-refundable tax credits. |
| Less than 90% came from Canadian sources | Applicable credits may be prorated. |
| No income during the non-resident period | Zero income does not automatically satisfy the 90% rule; applicable credits may be prorated. |
How Is Tax Credit Proration Calculated?
When the 90% threshold is not met, the applicable credits may be adjusted according to the number of days you were a Canadian tax resident during the year.
A simplified way to understand the calculation is:
Annual tax credit amount × (Number of days as a Canadian tax resident ÷ 365)
The actual calculation should follow the CRA rules for the relevant tax year.
Benefits of Understanding the 90% Rule
Knowing how the 90% rule works can help newcomers understand their tax obligations and avoid mistakes when filing their first Canadian tax return.
Some key benefits include:
- Better tax planning: You can understand how your income before moving to Canada may affect your eligible tax credits.
- Correct tax reporting: Knowing what information the CRA requires can help you prepare a more complete tax return.
- Avoiding unexpected adjustments: Understanding the rule may help reduce the risk of incorrect credit claims and later reassessments.
- Clearer financial planning: You can better understand how eligible tax credits may affect your federal tax payable.
Limitations of the 90% Rule
Although the 90% rule helps determine eligibility for certain federal tax credits, it does not apply to every tax credit or benefit.
Keep these points in mind:
- It does not apply to every credit: Some tax credits have their own eligibility requirements and calculation methods.
- Provincial and territorial rules may differ: Provincial and territorial tax credits can have separate rules. Quebec also has its own provincial tax system.
- It does not determine tax residency: The rule is relevant after your Canadian tax residency status and date have been established.
- It does not guarantee a tax refund: Non-refundable tax credits reduce tax payable. They do not automatically result in a cash payment.
- Income details must be accurate: Incorrectly reporting Canadian-source or foreign-source income can affect the calculation.
Common Misconceptions About the 90% Rule
There are a few misunderstandings about the 90% rule that newcomers should avoid.
| Myth | Fact |
| Every newcomer automatically qualifies for full federal tax credits. | Eligibility depends on the 90% test and the requirements for individual credits. |
| Foreign income earned before moving to Canada is never relevant. | It can be included when calculating net worldwide income for the non-resident period. |
| Having zero income before arriving automatically satisfies the 90% rule. | Zero income does not automatically meet the test under the CRA guidance applicable to 2024 and later tax years. |
| The rule applies to every tax credit. | It affects certain federal non-refundable tax credits. Other credits may follow separate rules. |
| Getting permanent residence automatically makes someone a Canadian tax resident. | Tax residency depends on residential ties and individual circumstances, not immigration status alone. |
Related Questions
Is the 90% Rule Based on Immigration Status or Tax Residency?
The 90% rule is connected to Canadian tax residency, not simply your immigration status. Becoming a permanent resident does not automatically establish your tax residency date. The CRA considers your residential ties and circumstances to determine when you became a Canadian tax resident.
Does Foreign Income Count Under the 90% Rule?
Yes. Foreign income earned during the period before you became a Canadian tax resident can be included in your net worldwide income. The CRA considers this amount when determining what percentage of your income came from Canadian sources.
What Happens If I Move to Canada Halfway Through the Year?
If you become a Canadian tax resident halfway through the year, your tax return generally needs to reflect your residency period. Your income from before and after the residency date may be treated differently, and the 90% rule can affect certain federal tax credits.
Can International Students Be Affected by the 90% Rule?
Yes, international students may be affected if they become Canadian tax residents during the year. However, having a study permit does not automatically make someone a tax resident. The CRA considers residential ties and other relevant circumstances.
What If I Do Not Meet the 90% Rule?
If you do not meet the 90% threshold, you may still qualify for certain federal non-refundable tax credits. However, the applicable credits may be reduced based on the number of days you were a Canadian tax resident during the year.
Is Income Earned Before Moving to Canada Taxable in Canada?
Income earned before becoming a Canadian tax resident is generally not taxed in Canada as income earned during your Canadian residency period. However, it may still be relevant when calculating the 90% threshold and for certain other tax reporting requirements.
