Quick Answer
The short answer: gather your T4 slips and other income documents, create a CRA My Account, choose a filing method (NETFILE software or a tax professional), enter your information, claim all eligible deductions, and submit before April 30, 2026. Most Canadians receive a refund within two weeks. The sections below walk you through every step in detail — including what documents you need, which deductions you can claim, and how to avoid the most common mistakes.
What Is a Canadian Personal Tax Return?
Every Canadian resident must file a T1 General Income Tax and Benefit Return each year to report income earned in the previous calendar year. For the 2025 tax year, you are filing a return that covers January 1 to December 31, 2025. The CRA uses your return to calculate whether you owe tax or are entitled to a refund, and to determine your eligibility for benefits like the GST/HST credit, Canada Child Benefit (CCB), and Ontario Trillium Benefit.
Even if you had no income in 2025, filing a return is often worth doing — it establishes your eligibility for benefits and carries forward tuition and capital loss credits to future years.
What Is the Deadline to File in 2026?
The standard filing deadline for most Canadians is April 30, 2026. If you or your spouse is self-employed, you have until June 15, 2026 to file — but any taxes owed are still due by April 30. Missing the deadline when you owe money results in a 5% late-filing penalty plus 1% interest per month on the outstanding balance.
- April 30, 2026 — Deadline for most individuals
- April 30, 2026 — Balance owing due (even for self-employed)
- June 15, 2026 — Extended filing deadline for self-employed individuals
- December 31, 2025 — Last day to contribute to RRSP for the 2025 tax year (60-day window applies)
- March 1, 2026 — Last day to make 2025 RRSP contributions
What Documents Do You Need Before You File?
Before you sit down to file, gather every income and deduction document from 2025. Starting early saves time and prevents you from filing an incomplete return that the CRA may question.
- T4 slips — Employment income from every employer you worked for in 2025
- T4A slips — Other income: pension, retirement, or self-employment payments
- T5 slips — Investment income: interest, dividends from Canadian sources
- T3 slips — Trust income: mutual fund distributions
- T2202 — Tuition and education amounts (students)
- RRSP contribution receipts — From your financial institution
- Medical expense receipts — Prescription drugs, dental, vision, medical devices
- Charitable donation receipts — Official receipts from registered charities
- Childcare expense receipts — Daycare, summer camps, after-school programs
- T4E — Employment Insurance benefits
- T4RSP / T4RIF — RRSP/RRIF withdrawals
- Rental income records — Income and all related expenses if you rent out property
- Business income and expense records — If self-employed
- Notice of Assessment from 2024 — Carries forward RRSP room and other amounts
How Do You Actually File Your Taxes?
There are three main ways to file your Canadian personal tax return:
- NETFILE software — Use CRA-certified tax software (e.g., TurboTax, Wealthsimple Tax, StudioTax) to prepare and electronically file your return directly with the CRA. Most software is free for simple returns.
- Tax professional — Hire a tax preparer or accountant (like Taxxel) to prepare and file on your behalf. Recommended if you have self-employment income, rental property, a corporation, or a complex situation.
- Paper return — Download and mail the T1 General form. The CRA discourages this method as it results in slower processing and refunds.
For most Canadians with a simple T4 and standard deductions, CRA-certified software is sufficient. If you have self-employment income, multiple income sources, a spouse with income splitting opportunities, or you received a CRA letter, working with a tax professional typically pays for itself in additional credits and avoided errors.
Which Deductions and Credits Can You Claim?
Deductions reduce your taxable income (worth more if you are in a higher bracket), while credits directly reduce the tax you owe. Here are the most valuable ones most Canadians miss:
- RRSP deduction — Contributions up to your deduction limit reduce taxable income dollar for dollar
- Basic Personal Amount — Every Canadian claims a federal credit on the first ~$15,700 of income
- Spousal Amount — If your spouse earned less than $15,700 in 2025
- Medical Expenses — Amounts exceeding 3% of your net income or $2,635 (whichever is less)
- Charitable Donations — 15% federal credit on first $200, 29–33% on amounts above $200
- Home Office Expenses (self-employed) — Proportional share of rent, utilities, internet for home workspace
- Moving Expenses — If you moved 40+ km closer to a new job or school
- Child Care Expenses — Daycare, babysitters, camps — up to $8,000 per child under 7
- Tuition Tax Credit (students) — Eligible tuition from T2202; unused amounts transfer to parents or carry forward
- Disability Tax Credit — If you or a dependant has a severe, prolonged impairment
- First Home Buyers' Amount — $10,000 credit if you purchased your first qualifying home in 2025
- Canada Caregiver Credit — If you support a dependent with a physical or mental impairment
What Happens After You File?
After submitting your return via NETFILE, the CRA typically issues a Notice of Assessment (NOA) within two weeks. The NOA confirms the refund amount or balance owing, your RRSP deduction limit for next year, and any adjustments the CRA made to your return.
If you disagree with an assessment, you have 90 days from the date of the NOA to file a formal objection. If you receive a request for more information or a review letter, respond promptly and with documentation — or call a tax professional for guidance.
What Are the Most Common Filing Mistakes?
- Missing T-slips — Employers and institutions must issue slips by end of February. Check CRA My Account if you are missing one.
- Forgetting to report all income — Side gigs, freelance work, cash income, and tips are all taxable.
- Claiming ineligible expenses — Only expenses directly related to earning income are deductible.
- Missing spousal or family income splitting opportunities — Pension income splitting and spousal RRSP contributions can reduce your combined tax bill.
- Not carrying forward unused tuition or capital losses — These do not expire and can save significant tax in future years.
- Filing late when you owe — Penalties start immediately on April 30. File even if you cannot pay.
Should You Use a Tax Professional?
A tax professional is worth considering if you are self-employed, own rental property, have a corporation, received a CRA notice, moved provinces, immigrated or emigrated in 2025, have foreign income, or just want peace of mind. The cost of professional filing is also tax-deductible as a carrying charge if your return includes investment income.
At Taxxel, personal tax filing starts at $49 — a flat fee with no per-form charges. We file by NETFILE, provide WhatsApp support, and offer service in English, Punjabi, and Hindi.
