Yes, you can file tax returns for multiple years (including two years at once) in Canada, but each year must be prepared and submitted separately using the appropriate forms for that specific tax year. While you can file them at the same time, they are processed individually by the Canada Revenue Agency (CRA).
Fortunately, if you have ignored your taxes in the past, you can file taxes for multiple years in Canada. You have 10 years to file an income tax return in Canada. Before this 10-year deadline, you can request relief from the CRA to: Issue an adjustment or refund beyond the standard 10-year period.
You can file two years of tax returns, however, they must be completed separately. For example, you would have to input your 2020 tax forms in your 2020 tax return and your 2021 tax forms in your 2021 tax return.
The majority of Canadians must file taxes every year, regardless of whether they owe taxes. If you live in Canada, you must file a tax return with the Canada Revenue Agency (CRA) each year by April 30, though self-employed individuals have until June 15.
While most tax cases result in financial penalties, willful tax evasion — including failure to file for multiple years — can lead to criminal charges. If convicted under the Income Tax Act, penalties include: Fines ranging from 50% to 200% of taxes owed. Up to five years in prison in extreme cases.
Filing ITR for Previous Assessment Years
A belated return may be filed up to three months prior to the end of the relevant assessment year, or before the assessment is completed, whichever comes earlier. So, for FY 2024-25 (AY 2025-26), the ITR filing last date 2025 for belated return is 31st December 2026.
Willful failure to file a tax return is a crime, which could lead to your arrest, prosecution, and, if you are convicted, penalties including jail time and tens of thousands of dollars in fines. You will also gain a criminal record, which could have untold damage to your career and reputation.
When convicted of tax evasion: you must still pay the full amount of taxes owing, plus interest and any civil penalties assessed by the CRA. you may be fined up to 200% of the taxes evaded. you may be imposed a jail term of up to five years.
April 30, 2025: Deadline to file your 2024 personal income tax return and pay any taxes owed. June 16, 2025: If you're self-employed or have a self-employed spouse or common-law partner, your filing deadline is extended to this date. However, any taxes owed are still due by April 30, 2025.
Can you file taxes from previous years? If you didn't file a federal income tax return for the last few years, you might wonder if you're still responsible for filing those late returns. The answer is “yes” in most cases. But, if you didn't meet the filing requirements, you don't need to file a prior year's tax return.
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
You can generally file back taxes to claim a refund within three years of your original return's filing date or two years of paying the tax, whichever is later; however, for unreported income (especially significant amounts or foreign income) or failure to file, the IRS can often go back six years or even longer, requiring you to file all missing returns to avoid penalties and interest, with deadlines extended for specific exceptions like bankruptcy or large omissions.
You may get a bigger tax refund when married or filing as a common-law couple than if single. Your tax rates are unchanged, but you may be able to deduct some of your spouse's unused deductions and tax credits from your potential tax liability.
You might have to pay IRS penalties and interest if you file your federal income tax return after the April deadline, your due date isn't extended, and you end up with a tax bill. First, the IRS charges a 5% penalty per month on any tax due if your return is filed late. The penalty is capped at 25% of the tax owed.
So, while you may file or submit your tax return twice, only one return will be accepted by the IRS. Therefore, you may submit duplicate tax returns, but only one will actually be accepted and filed.
Yes, it's possible to go to jail for not filing taxes — but it's rare. The IRS usually seeks to collect money through penalties, interest, and enforcement actions like liens or levies. Jail time is reserved for willful tax evasion or fraud.
It is relatively rare for a Canadian to be convicted of tax evasion but it does happen. Some Statistics: Between 2019 and 2024 there were 135 convictions with a total of $25.1 million in fines imposed: 58 individuals received jail time totalling 108 years.
Repeated failure to report income penalty: If you fail to report income of $500 or more on your return more than once within a four-year period, the CRA can impose a penalty equal to whichever is less: 10% of the unreported income or 50% of the tax owed on that amount.
You can't get a credit or refund if you don't file the claim within 3 years of filing your original return, or 2 years after paying the tax, whichever is later, unless you meet an exception that allows you more time to file a claim.
There's no official limit to how many years you can go without filing taxes, but the IRS expects you to file if required, and the statute of limitations on the IRS assessing tax or collecting never starts until you actually file, meaning they can pursue unfiled returns from any year, even decades old. While the IRS often focuses on the last six years, waiting increases penalties and interest, and you risk losing any potential refunds after three years; proactively filing past-due returns is always best.
If you're worrying about the consequences, there's good news. You can still file your ITR for the last three years using the ITR-U form. This opportunity allows taxpayers to rectify missed or incorrect filings and stay compliant with tax regulations.
