Do I Have to File a Tax Return in Canada?

Find out whether you are required to file a Canadian income tax return and when filing may benefit you even if not required.

The short version

  • You must file if you owe tax, if CRA asks you to, or if you sold property, including your home.
  • You also have to file to get benefits: the Canada Child Benefit, the Canada Groceries and Essentials Benefit (formerly the GST/HST credit), the Guaranteed Income Supplement and the Canada Workers Benefit.
  • If you have a spouse or common-law partner, they have to file too, for the family benefits to be calculated.
  • With zero income, filing is still usually worth hundreds or thousands of dollars, and those benefit payments are non-taxable income.

Do I Have to File Taxes in Canada?

“I didn't make anything, so I don't need to file.” It's the most expensive sentence in Canadian tax. The law only requires some people to file, but CRA pays benefits only to people who do. So the real question isn't “do I have to?” It's “can I afford not to?”

CRA's List: You Have to File If…

For the 2025 return, CRA says you should file if any of these apply. (The 2026 list is expected to be the same in substance.)

  1. CRA sent you a request to file.
  2. You have to pay tax, or you want a refund.
  3. You or your spouse or common-law partner want to start or keep receiving benefits and credits, such as the Canada Child Benefit, the Canada Groceries and Essentials Benefit, provincial benefits, or the Guaranteed Income Supplement.
  4. You want the Canada Workers Benefit, including advance payments.
  5. You and your spouse are splitting pension income.
  6. You sold or otherwise disposed of capital property, including your home, or had a taxable capital gain.
  7. You have to repay Old Age Security or Employment Insurance benefits.
  8. You still owe repayments on a Home Buyers' Plan or Lifelong Learning Plan withdrawal.
  9. Your net self-employment income plus pensionable employment income is more than $3,500, so you owe CPP contributions.
  10. You pay EI premiums on self-employment or other eligible earnings.
  11. You had a non-capital loss you want to use in other years.
  12. You want to carry forward unused tuition or transfer it.
  13. You want your income on record so it builds RRSP room for future years.

Selling your home is the one people miss most. Since 2016 every sale of a principal residence must be reported, even when no tax is owed. See the principal residence exemption.

Who Usually Gains the Most by Filing

  • Students, to bank tuition credits and build RRSP room.
  • Newcomers, because benefits start only once CRA knows you; see first tax return in Canada.
  • Parents, because the Canada Child Benefit is calculated from both parents' returns.
  • Seniors with low income, because the Guaranteed Income Supplement depends on filing.
  • Low-income workers, for the Canada Workers Benefit.
  • Newcomers to Canada, to start benefits in their first year.
  • Anyone who had tax withheld from a job they left partway through the year: often there's a refund waiting.

The amounts are in our guide to Canadian tax credits, and your own estimate is one minute away in the income tax calculator.

Haven't Filed for a While?

You can file returns for past years at any time. CRA's online filing (NETFILE) currently accepts returns back to 2018; earlier years go on paper. Refunds are generally limited to the last ten years, so old refunds expire quietly. If you owe, file now: penalties grow monthly (see filing taxes late) and interest daily. Our guide to CRA tax problems covers catching up, and find the right tax help if it's more than a year or two.

When Is It Due?

The 2026 return is due April 30, 2027, or June 15, 2027 if you or your spouse had self-employment income (with any balance still due April 30). The full calendar is on Canadian tax deadlines. Ready to file? Read how to file taxes in Canada.

Filing Questions

Do I have to file taxes if I had no income?

Not always, but you should. Filing is how CRA pays the Canada Child Benefit, the Canada Groceries and Essentials Benefit, the Guaranteed Income Supplement and provincial benefits. With a spouse or common-law partner, both of you need to file.

Do I have to file if I sold my house?

Yes. Every sale of a principal residence must be reported on Schedule 3 and Form T2091(IND), even if the whole gain is exempt.

Do students need to file a tax return?

Often not legally, but filing records tuition credits to use later and builds RRSP room, and can bring refunds of tax withheld from part-time jobs.

Is there a minimum income to file taxes in Canada?

There is no single income threshold. You must file if you owe tax or meet any of CRA's other conditions, such as selling property, owing CPP on self-employment income over $3,500, or repaying OAS or EI.

How far back can I file?

Any year. NETFILE currently accepts returns from 2018 onward; earlier years are filed on paper. Refunds are generally limited to the last ten years.
