Filing your first tax return in Canada can feel confusing, especially if you earned income in another country before arriving. You may not know which income to report, what documents to collect or whether you need to file when you did not work in Canada.
Canada’s income tax system is based largely on residency for tax purposes. Your immigration status alone does not determine how you are taxed. The date you established residential ties with Canada can affect the income you must report, the credits you may claim and the forms you need to complete.
This guide explains how newcomers can prepare and file their first Canadian tax return.
What Is a Canadian Tax Return?
An income tax and benefit return is used to report your income, deductions, tax credits and taxes already paid during a calendar year.
The Canada Revenue Agency, commonly called the CRA, processes the return and determines whether:
- You are entitled to a refund
- You owe additional tax
- You have no balance owing
- You qualify for certain benefits or credits
The Canadian tax year for most individuals runs from January 1 to December 31. You normally prepare and file the return during the following year.
Canada uses a self-assessment tax system. This means you are responsible for reporting your information accurately, even when an employer, bank or other organization has already sent a copy of an information slip to the CRA.
Do Newcomers Need to File a Tax Return?
Whether you are legally required to file depends on your income and personal circumstances. You may need to file if you owe tax, have taxable income, disposed of certain property or received a request from the CRA.
However, filing can still be valuable even when you did not earn much income or do not owe tax.
Submitting a return can help you:
- Receive an eligible tax refund
- Establish your Canadian tax record
- Continue receiving eligible benefits and credits
- Report tuition or other amounts that may be carried forward
- Establish certain contribution amounts for future years
- Provide financial records that may be requested for other purposes
The CRA recommends filing a return every year to maintain eligible benefit and credit payments, including during years when you have little or no income. The CRA’s official newcomer tax information explains how the system applies to people who recently arrived.
Do not assume that you have nothing to file simply because you arrived near the end of the year or had not started working.
Determine Your Residency Status for Tax Purposes
Before preparing your return, determine when you became a Canadian resident for income tax purposes.
Tax residency is different from immigration status. Becoming a permanent resident, receiving a work permit or entering Canada does not automatically establish the correct tax residency date in every situation.
The CRA generally considers the residential ties you establish with Canada.
Significant residential ties can include:
- A home in Canada
- A spouse or common-law partner living in Canada
- Dependants living in Canada
Other ties may include provincial health coverage, Canadian identification, personal property, bank accounts and social connections.
For many newcomers, tax residency begins when they arrive and establish a home and other meaningful ties. However, circumstances involving repeated visits, family members living abroad or continuing ties to another country can make the determination more complicated.
Tax treaties between Canada and other countries may also affect residency. The CRA provides guidance for determining your residency status.
If you are uncertain, seek qualified assistance before selecting a date. Your residency date can affect how your income and tax credits are calculated.
Keep Evidence of Your Arrival and Residency Date
Your first return may ask for the date you entered Canada or became a Canadian resident for tax purposes.
Keep documents that may help support this date, including:
- Passport and travel records
- Immigration documents
- A rental agreement or home purchase record
- Canadian employment records
- Provincial health coverage documents
- School registration records
- Records showing when your spouse or dependants arrived
The day you first visited Canada may not be the same day you became a resident for tax purposes. Use the date supported by your actual circumstances.
Understand Which Income You Must Report
A newcomer’s first Canadian tax year may contain two separate periods:
| Period | General treatment |
|---|---|
| Before becoming a Canadian tax resident | Certain income may need to be disclosed or reported depending on its source and purpose |
| After becoming a Canadian tax resident | Worldwide income generally must be reported |
Worldwide income means income from sources both inside and outside Canada.
Depending on your circumstances, reportable income after becoming a resident could include:
- Canadian employment income
- Foreign employment income
- Self-employment income
- Rental income
- Interest
- Dividends
- Pension income
- Capital gains
- Other investment income
Income earned before you became a Canadian resident may be treated differently. However, the CRA may still require information about pre-arrival income when calculating certain credits and benefits.
You may also have Canadian filing obligations for Canadian-source income received before becoming a resident.
The CRA provides additional instructions for completing a return as a newcomer.
Consider obtaining professional assistance if you owned foreign investments, operated a business, received foreign rental income, sold property or continued working for an overseas employer after moving to Canada.
Convert Foreign Income to Canadian Dollars
Amounts reported on a Canadian tax return generally need to be stated in Canadian dollars.
Do not enter a foreign-currency amount as though it were already Canadian currency. Use an appropriate exchange rate based on the type of income and when it was received.
Keep a record showing:
- The amount in the original currency
- The currency involved
- The Canadian-dollar amount
- The exchange rate used
- The date or period connected to the income
- Where the exchange rate was obtained
A yearly average exchange rate may be appropriate for some income received regularly throughout the year. A transaction-date rate may be required in other situations.
If you paid tax to another country on income also reported in Canada, you may qualify for a foreign tax credit. Eligibility and calculations depend on the type of income, foreign tax paid and any applicable tax treaty.
Apply for a Social Insurance Number
A Social Insurance Number, or SIN, is a nine-digit number used for employment, taxes and government programs.
If you are eligible but do not have one, review the official instructions to apply for a Social Insurance Number.
Your name, date of birth and other identification details on your first tax return should match your SIN record. Inconsistent information can cause processing delays.
If you applied for a SIN but will not receive it before the filing deadline—or you are not eligible for one—you may need an Individual Tax Number or Temporary Tax Number. Follow the CRA’s instructions instead of inventing a number or using someone else’s SIN.
Keep your SIN confidential. Do not include it on a résumé, provide it to an unknown person or send it through an unsecured message.
Gather Your Tax Documents
Collect your tax documents before beginning the return. The exact documents required will depend on your employment, family situation, investments and eligible expenses.
| Document or information | Why it may be needed |
|---|---|
| Social Insurance Number | Identifies your Canadian tax record |
| Date of entry or residency | Establishes your part-year residency period |
| T4 slip | Reports employment income and payroll deductions |
| T5 slip | Reports certain interest and investment income |
| T4A slip | May report pensions, scholarships or other income |
| Tuition certificate | May support eligible tuition amounts |
| Foreign income statements | Help calculate foreign income |
| Foreign tax records | May support a foreign tax credit |
| Business records | Support self-employment income and expenses |
| Rental property records | Support rental income and expenses |
| RRSP receipts | May support an eligible deduction |
| Medical receipts | May support eligible medical expense credits |
| Donation receipts | May support eligible charitable credits |
| Childcare receipts | May support an eligible expense claim |
| Spouse’s income information | May be required for benefit calculations |
| Banking information | May be used to arrange direct deposit |
Not every document will apply to every newcomer.
Canadian employers and other payers generally issue tax slips after the end of the calendar year. Review each slip carefully. Confirm that your name, SIN, income and deductions appear correctly.
Contact the organization that issued the slip if something is missing or incorrect. Do not change an official slip yourself.
Use the Correct Provincial Tax Package
Provincial or territorial tax is generally based on where you lived on December 31 of the tax year.
A newcomer who lived in Toronto on December 31 would normally use the Ontario tax package, provided the individual is considered a resident of Canada and Ontario under the applicable rules.
People who lived outside Canada at the end of the year, moved between provinces or had an unusual residency situation may need to follow different instructions.
The CRA’s official income tax packages contain the return, schedules and provincial or territorial forms.
Choose How You Will File
Newcomers may be able to file electronically, submit a paper return, use a qualified tax professional or receive help from a free tax clinic.
Filing Electronically
Many individuals can prepare and submit their returns through NETFILE using CRA-certified tax software.
Some first-time filers can submit electronically when the CRA can verify their personal information. If electronic filing is not available for your circumstances, you may need to submit a paper return.
Use the CRA’s official list of certified tax software before choosing a product. Software options can have different features and prices.
Filing a Paper Return
You can download the correct tax package, complete the forms and mail the return to the appropriate CRA tax centre.
Paper returns generally take longer to process. Confirm the correct mailing address and follow the instructions concerning supporting documents.
The CRA provides current guidance for filing a paper tax return.
Using a Tax Professional
Professional assistance may be useful when a first return includes:
- Foreign assets or investments
- Foreign business income
- Rental properties
- Self-employment
- Income taxed in another country
- Multiple possible tax residencies
- A complicated immigration or arrival history
- The sale of significant property
Review the completed return before it is submitted. You remain responsible for the accuracy of the information, even when another person prepares it.
Getting Help From a Free Tax Clinic
Newcomers with modest incomes and simple tax situations may qualify for assistance through a free tax clinic.
Community organizations participating in the Community Volunteer Income Tax Program arrange for volunteers to prepare eligible returns. The CRA provides a tool to find a free tax clinic.
These clinics may not be able to handle complicated foreign income, self-employment or foreign-property situations.
Claim Only Eligible Deductions and Credits
Tax deductions and credits may reduce your taxable income or tax payable. Each one has specific eligibility requirements.
Depending on your circumstances, relevant items might include:
- Eligible tuition amounts
- Registered Retirement Savings Plan contributions
- Childcare expenses
- Certain medical expenses
- Eligible charitable donations
- Qualifying moving expenses
- Employment expenses supported by the required forms
- Foreign tax credits
- Canada Workers Benefit eligibility
Some federal non-refundable tax credits may be prorated according to the number of days you were a resident during the year. Your income during the period before residency may also affect whether you can claim certain amounts.
Having a receipt does not automatically make an expense eligible. Confirm that the expense qualifies and that you have all required documentation.
File Even If You Had No Canadian Employment Income
You may still need or benefit from filing if you did not work in Canada during your first year.
Filing allows the CRA to calculate certain benefits and credits. It can also establish your tax record and preserve eligible amounts for future years.
If you have a spouse or common-law partner, the CRA may need information about their income when calculating household benefits. This can apply even if your spouse lives outside Canada or earned all their income in another country.
Do not report your spouse’s income as zero simply because it was not earned in Canada. Follow the CRA’s instructions for converting and disclosing the amount.
Know the Filing and Payment Deadlines
For the 2025 tax year, most individuals were required to file their returns and pay any balance owing by April 30, 2026.
Self-employed individuals—and people whose spouse or common-law partner was self-employed—generally had until June 15, 2026 to file, subject to specific exceptions. However, any balance owing was generally still due by April 30, 2026.
Deadlines may change depending on the tax year and whether a date falls on a weekend or public holiday. Confirm current dates through the CRA’s personal tax deadlines page.
If you missed a deadline, file as soon as possible. Waiting longer may increase applicable interest and penalties or interrupt benefit payments.
Review Everything Before Filing
Check your return carefully before submitting it.
Make sure that:
- Your name matches your SIN record
- Your SIN is correct
- Your address is current
- Your date of birth is correct
- Your marital status is accurate
- Your residency or arrival date is correct
- All required Canadian income is included
- All required foreign income is included
- Foreign amounts are converted into Canadian dollars
- Your spouse’s information is reported correctly
- Deductions and credits are supported by documents
- Your direct-deposit information is accurate
Mistakes can delay the processing of a first return because the CRA may have limited information about you in its records.
What Happens After You File?
The CRA will process your return and issue a Notice of Assessment.
The notice explains whether:
- The return was assessed as filed
- The CRA changed any amounts
- You will receive a refund
- You owe a balance
- You have amounts available to carry forward
Compare the Notice of Assessment with the return you submitted. If the CRA changed something, read the accompanying explanation.
Keep the notice securely. It may be needed to access CRA services or provide proof of income for certain financial and government purposes.
You can learn more through the CRA’s guide to understanding your Notice of Assessment.
Register for a CRA Account
After your first return is processed, you can register for a CRA account using an available identity-verification method.
Your account can help you:
- View your Notice of Assessment
- Check your refund status
- Review tax slips received by the CRA
- Update certain personal information
- Review benefits and credits
- Submit requested documents
- Change a previously filed return
- Arrange direct deposit
Use only the official Government of Canada website. The CRA explains how to register for an online account.
Keep Your Tax Records
The CRA generally advises taxpayers to keep supporting documents for at least six years after filing.
Important records may include:
- Tax slips
- Foreign income statements
- Foreign tax records
- Exchange-rate calculations
- Business and rental records
- Tuition documents
- Medical and donation receipts
- RRSP contribution receipts
- A copy of the return
- Your Notice of Assessment
Digital copies can be useful, but make sure they are complete, readable and stored securely.
Common Mistakes Newcomers Should Avoid
Confusing Immigration Status With Tax Residency
Your tax residency is determined by your residential ties and other relevant circumstances, not simply the type of immigration document you possess.
Forgetting Foreign Income
Income from outside Canada may need to be reported after you become a Canadian resident for tax purposes, even if the money remains in another country.
Using the Wrong Residency Date
The date you first entered Canada may not be the same as the date you established Canadian tax residency.
Ignoring Pre-Arrival Income
Income earned before residency may still be needed for benefit and credit calculations.
Forgetting to Convert Foreign Currency
Foreign amounts generally need to be converted into Canadian dollars using an appropriate exchange rate.
Assuming You Do Not Need to File Without Employment
Filing may still be necessary or beneficial when you had little or no Canadian employment income.
Claiming Expenses Without Checking Eligibility
A receipt does not automatically make an expense deductible. Each deduction or credit has its own conditions.
Providing Your SIN to the Wrong Person
Protect your SIN from identity theft. A legitimate tax preparer may need it to complete your return, but you should verify the person or organization before providing sensitive information.
Protect Yourself From CRA Scams
Newcomers are sometimes targeted by scammers pretending to represent the Canada Revenue Agency.
Be suspicious of messages that:
- Threaten immediate arrest or deportation
- Demand payment through gift cards or cryptocurrency
- Request online banking passwords
- Ask you to send your SIN through an unsecured message
- Pressure you to pay without verifying the debt
- Promise a guaranteed refund in exchange for personal information
If you receive a suspicious message, do not use the phone number or link included in it. Visit the official Canada.ca website independently or contact the CRA using publicly listed information.
Frequently Asked Questions
Do newcomers have to file taxes in their first year in Canada?
It depends on their residency, income and personal circumstances. Filing may be required when tax is owed or another filing condition applies. It may also help newcomers receive refunds and maintain eligible benefits and credits.
Do I report income earned before moving to Canada?
Pre-arrival income may be treated differently from income earned after becoming a Canadian tax resident. However, the CRA may still require it for certain benefit and credit calculations. Canadian-source income received before residency may create additional obligations.
Do I have to report foreign income?
After becoming a Canadian tax resident, you generally report income from sources inside and outside Canada. The exact treatment depends on your residency status and the type of income.
Can a first-time filer submit a return online?
Some first-time filers can use NETFILE when the CRA can verify their identity and personal information. Other newcomers may need to submit a paper return.
Can I file without a Social Insurance Number?
If you are eligible for a SIN, apply for one. If you cannot receive it before the deadline or are not eligible, an Individual Tax Number or Temporary Tax Number may be appropriate. Follow the CRA’s instructions for your circumstances.
Should I file if I did not work in Canada?
Filing may still help establish your tax record and allow the CRA to calculate benefits and credits. You may also have income or reporting obligations unrelated to Canadian employment.
Where can newcomers get free tax help?
People with modest incomes and simple tax situations may qualify for a CRA-supported free tax clinic. Complicated foreign income, business or property matters may require specialized assistance.
What should I do if I make a mistake?
Wait until the CRA processes your return and issues your Notice of Assessment. You can then request a change through an available CRA method. Do not submit a second return for the same year unless the CRA instructs you to do so.
