In Canada, the statute of limitations for the Canada Revenue Agency (CRA) to reassess a personal tax return is generally three years from the date of the initial Notice of Assessment. For corporations, this is typically three years for Canadian-controlled private corporations (CCPCs) and four years for others.
The prescribed limitation period in the Income Tax Act is 10 years; this means that after 10 years, the Canada Revenue Agency is legally prevented from collecting on a tax debt.
The 10-year rule is a guideline that some campgrounds and RV parks use to restrict access to older recreational vehicles. It means that only RVs manufactured within the last 10 years are allowed to stay at the campground, or they must pass an inspection to ensure they meet appearance and safety standards.
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.
In Canada, taxpayers generally have three years from the date of the original Notice of Assessment to request a reassessment for a refund under the Income Tax Act. If no return was filed or no assessment issued, the three-year period typically starts from the end of the taxation year in question.
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.
Submitting a Claim for Refund
Generally, you must file a claim for a credit or refund within three years from the date you filed your original tax return or two years from the date you paid the tax, whichever is later.
There is no hard limit on how many years you can file back taxes. However, to be in “good standing” with the IRS, you should have filed tax returns for the last six years. If you're due a refund or tax credits, you must file the return within three years of the original due date to claim it.
If you haven't filed taxes for 20 years, the IRS can take several actions, including assessing penalties and interest, filing a substitute return on your behalf, placing a federal tax lien on your property, garnishment of wages, or even pursuing criminal penalties and criminal charges in extreme cases.
Generally, CRA can only audit someone up to four years after a tax return has been filed, although, in some cases, such as cases of suspected fraud or misrepresentation, CRA can go farther back and there is no time-limit for the re-assessment.
If you owe taxes to the CRA and don't pay, they can arrange for part of your paycheque to go straight to the government; this is known as wage garnishment. They can even seize, freeze, and sell your assets without needing to go through the courts. If you ignore their notices, the CRA may freeze your bank account.
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.
Based on this data, approximately less than 10% of Canadians aged 55 to 64 have $1,000,000 or more saved up to carry them into retirement. However, there are ways to improve your odds of getting to $1-million-plus in retirement savings, but it will take work.
The limitations vary depending on the severity and classification of the offence. While summary conviction offences have one-year limitation periods, indictable serious offences typically have no statutory limitation period. Hybrid offences can have different limitation periods based on the chosen mode of prosecution.
Generally, you must keep all required records and supporting documents for a period of six years from the end of the last tax year they relate to.
The Limitation Act says that the limitation period for simple contract debts is six years. The cause of action (when the limitation period starts running) for simple contract debts is usually when your agreement says the creditor is able to take court action against you.
If you haven't filed your Canadian taxes for three years, you could face financial and legal consequences. The good news? There are ways to fix it, like the CRA Voluntary Disclosure Program. This guide will break down what happens when you don't file, how to get back on track, and how Credit Canada can help.
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 haven't filed taxes in years, gather your financial documents (income statements, receipts) for those years, request wage and income transcripts from the IRS to ensure accuracy, and file all missing returns ASAP, as the IRS prefers compliance over pursuing criminal action, even if you can't pay immediately; file to claim refunds (within 3 years) and avoid bigger penalties, and then contact the IRS for payment options like installment agreements if needed.
Quick Answer: The IRS can go back indefinitely if you've never filed a return. While they generally require the last six years to be filed to get back into compliance, there's no statute of limitations on unfiled tax returns. This means the IRS can pursue you for older years at any time.
Keep Forever
Taxes aren't determined by age, so you will never age out of paying taxes. People who are 65 or older at the end of 2025 have to file a return for that tax year (which is due in 2026) if their gross income is $16,550 or higher.
Request a transcript from the IRS
The IRS 7-year rule primarily applies to keeping records for claiming a deduction for bad debts or losses from worthless securities, allowing a longer period to file for a credit or refund, but it's not a universal audit limit; it's often a recommended safe buffer for general record-keeping, with the standard IRS audit period usually being 3 years, extending to 6 years for substantial income omission (over 25%) or foreign income issues, and indefinitely for fraud.
Taxpayers usually have three years to file and claim their tax refunds. The three-year deadline for filing 2019 returns to claim a refund was in 2022, but the IRS postponed the deadline to July 17, 2023, due to the COVID-19 pandemic.
