T1 Personal Tax Return in Canada: Step by Step for the 2025 Tax Year

The T1 personal tax return in Canada is the Income Tax and Benefit Return that every individual files for a calendar year. It reports your income, subtracts deductions, applies federal and provincial credits and decides whether you owe tax or receive a refund and benefits. For the 2025 tax year, the return you file in 2026 follows the same logic whether you are a newcomer in Mississauga, an owner of an Indian flat living in Calgary, or a U.S. citizen working in Surrey. This guide walks through the steps, the key forms and lines, and the checks that matter when you also have foreign income.

Who must file a T1 return?

You should file every year if you live in Canada and want your credits and benefit payments, and you must file if you owe tax, if the CRA asks you to, or if you sold or are considered to have sold capital property. Newcomers file for the year they become resident; non-residents file only in specific cases (see our non-resident guide). The CRA's list of situations covers residents, factual residents temporarily abroad, non-residents, deemed residents, non-residents with Canadian rental income, part-time U.S. residents and emigrants.

How to file a T1 personal tax return in Canada, step by step

1. Confirm your residency and province. The residence status and the date you became resident or left decide what income is included; see the Canada tax residency rules. The province where you lived on December 31 sets the package and provincial tax. Quebec residents also file with Revenu Québec.
2. Pick a filing method. Options are NETFILE-certified software, EFILE through a professional tax preparer, a paper return, SimpleFile for eligible lower-income filers with simple situations, or a free tax clinic run by volunteers.
3. Gather your slips and receipts. See the checklist below. Most slips are issued by the end of February; T3 and T5013 slips can arrive by the end of March, and RRSP receipts for contributions in the first 60 days of the year may not arrive until May.
4. Record your income. Employment (T4), pension and retirement (T4A, T4A(P), T4A(OAS), T4RSP, T4RIF), investment (T5, T3), securities sales (T5008) and benefits (T4E). Add income without a slip, such as foreign wages, foreign rent and interest.
5. Convert foreign amounts to Canadian dollars. Use the Bank of Canada exchange rate on the day you received the income. For a foreign pension received at different times during the year, the CRA says to use the average annual rate.
6. Claim deductions to reach net income (line 23600). Common ones are the RRSP deduction (line 20800, supported by Schedule 7), the FHSA deduction (line 20805), support payments (line 22000), the capital gains deduction (line 25400) and the other payments deduction (line 25600).
7. Claim credits. The basic personal amount is claimed on line 30000. For 2025 you can claim $16,129 if net income is $177,882 or less, $14,538 if it is above $253,414, and a worksheet amount in between. Other credits flow into line 35000.
8. Add schedules and forms. See the table below. Report capital property sales on Schedule 3; report a principal residence sale on Form T2091(IND).
9. Report foreign tax paid. If you paid foreign tax on income that Canada also taxes, claim the federal foreign tax credit on line 40500 using Form T2209. A U.S. or Indian credit for Canadian tax is claimed on the foreign return.
10. Check foreign reporting. If you held specified foreign property costing more than $100,000 at any time in 2025, file Form T1135; see the T1135 guide.
11. File and pay. Submit, note the confirmation number, and pay any balance by April 30, 2026. Payment methods include electronic options, a bank or credit union with a remittance voucher, and Canada Post.
12. Track the result. The notice of assessment appears in your CRA account after processing. See CRA My Account.

Documents and information checklist

• SIN, last year's notice of assessment and your NETFILE access code from your CRA account.
• All Canadian slips and receipts, plus foreign bank, brokerage and pension statements.
• A record of your date of entry or exit if you arrived or left in 2025.
• Foreign tax payment evidence, such as Indian TDS certificates or a U.S. Form 1099 summary.
• Property purchase and sale records for any disposition, including fair market value at entry for newcomers.
• Child care, medical, moving and tuition receipts.

Deadlines and penalties

Most individuals file and pay by April 30, 2026; a person who or whose spouse or common-law partner is self-employed files by June 15, 2026 but still pays by April 30. A late 2025 return with a balance attracts a penalty of 5% of the balance plus 1% for each full month, and interest accrues daily. Those dates have passed, so anyone who still has a 2025 return to file should do it now; the same steps apply, and the statutory dates for the 2026 return are April 30, 2027 and June 15, 2027. Full detail, with an example, is in our guide to Canada tax filing deadlines.

Worked example: a Mississauga couple

Neha earns $95,000 at a Mississauga employer (T4), Rahul earns $60,000 and they file separately. Neha also has Indian savings interest that converts to $2,000 in Canadian dollars at the Bank of Canada rates she used, and she contributes $10,000 to her RRSP before the deadline. Her net income on line 23600 is $95,000 plus $2,000 less $10,000, or $87,000. She claims the basic personal amount on line 30000 and any credit for Indian tax withheld on Form T2209, limited to the Canadian tax on that income. Both file by April 30, 2026. Her specified foreign property cost stays below $100,000, so no T1135 is needed. Her husband's benefits calculation uses both spouses' income, which is why each spouse's return matters.

If you also file in the U.S. or India

A Canadian resident with U.S. citizenship files Form 1040 and uses a foreign tax credit for Canadian tax; read the Form 1040 roadmap and U.S. citizens living in Canada. Someone with Indian income should keep Indian tax certificates and bank statements; the Indian side of the credit is explained in the Form 67 guide. Our foreign tax credits across three countries page shows how the three credits interact.

Mistakes to avoid

• Using the wrong province's package. It follows where you lived on December 31, 2025.
• Using the date of the transaction rather than the Bank of Canada rate for foreign amounts.
• Leaving out foreign income because no slip exists.
• Claiming foreign tax credits above the Canadian tax on that income.
• Failing to report the sale of a home that was your principal residence.
• Not keeping records. Hold supporting documents for six years.
