You have to file if you owe tax, if the CRA asks you to, or if one of a short list of situations applies to you. Even when none of them do, filing is usually worth it: your return is how the CRA works out your benefit payments, your refund and your future contribution room.

## When you have to file

You must file a return for the year if any of these apply:

- **The CRA sent you a request to file.**
- **You owe tax.** If the tax taken off your pay (or paid some other way) doesn't cover your tax for the year, you file and pay the difference.
- **You sold or gave away capital property**, such as shares or real estate, including a principal residence, or you had a taxable capital gain. See [the principal residence exemption](https://taxnotes.ca/guides/principal-residence-exemption/) if it was your home.
- **You have to repay** some of your Old Age Security or Employment Insurance benefits.
- **You still owe repayments** on money you took out of an RRSP under the Home Buyers' Plan or the Lifelong Learning Plan.
- **You owe Canada Pension Plan contributions on self-employment income.** This applies when your net self-employment income plus your pensionable employment income is more than $3,500. You also have to file if you pay EI premiums on self-employment income.
- **You and your spouse or common-law partner are jointly electing to split pension income.**

## Do you actually owe tax?

Generally, anyone resident in Canada for the year can claim the basic personal amount, a non-refundable credit that lets you earn a certain amount before federal income tax applies. For 2025 the full federal amount is $16,129; it's reduced for people with high net income.

Your provincial or territorial basic personal amount depends on where you lived at the end of the year and can differ from the federal one, so the point where provincial tax starts can be different. Compare them in the [personal credit amounts table](https://taxnotes.ca/rates/personal-credits/), or get an estimate for your province with the [income tax calculator](https://taxnotes.ca/calculators/income-tax/).

## When you should file anyway

Many payments are calculated from your return, so you need to file to get them, even with little or no income:

- the Canada child benefit and related provincial and territorial payments
- the Canada Groceries and Essentials Benefit and related provincial and territorial credits
- the Guaranteed Income Supplement
- the Canada workers benefit, including its advance payments

If you have a spouse or common-law partner, they need to file too.

Filing also keeps your RRSP deduction limit and FHSA participation room up to date, lets you carry forward or transfer unused tuition amounts, records a non-capital loss you can apply to other years, and adds to your Canada training credit limit. And if too much tax was deducted from your pay, filing is how you claim the refund. The details are in [why file even with no income](https://taxnotes.ca/guides/why-file-with-no-income/).

## When it's due

For most people, the return is due April 30 of the following year, and any balance owing has to be paid by the same day.

If you or your spouse or common-law partner carried on a business during the year, the filing deadline is June 15 instead (April 30 if the business expenses were mainly for a tax shelter investment). Any balance owing is still due April 30. See [deadlines for sole proprietors](https://taxnotes.ca/guides/deadlines-for-sole-proprietors/) for the full picture.

When a due date falls on a Saturday, Sunday or a public holiday the CRA recognizes, your return is on time if the CRA receives it, or it's postmarked, by the next business day.

Filing late can lead to interest and penalties, and it can interrupt your benefit and credit payments. If the date has already passed, see [missed the filing deadline?](https://taxnotes.ca/guides/missed-the-deadline/)

## Situations with different rules

Your filing obligations can be different depending on your residency status. That includes newcomers to Canada, people leaving Canada for good or for a while, non-residents (including those with Canadian rental income), deemed residents, international students and seasonal agricultural workers. The CRA's "Who should file a tax return" page, listed in the sources below, links to each one.

If someone died during the year, their legal representative (the executor, administrator or liquidator) may have to file a return for them. See [wills, estates and the final return](https://taxnotes.ca/guides/wills-and-estates/).

## Quebec residents

Revenu Québec runs its own provincial return, with its own rules about who must file. For example, you must file it if you were resident in Quebec on December 31 and you have to pay Quebec income tax, a Québec Pension Plan contribution, a Québec parental insurance plan premium or a health services fund contribution. You also file if you disposed of capital property, or if you want to receive the solidarity tax credit, among other situations on Revenu Québec's list.

## In short

- File if you owe tax, the CRA asks you to, or one of the situations above applies.
- File anyway if you want benefits, credits or a refund, or to keep your contribution room up to date.
- The deadline is April 30, or June 15 if you or your spouse ran a business, but any balance is due April 30 either way.
