The number of years you can go without filing taxes depends on many things. Because there are so many factors involved, it’s difficult to give a precise answer. However, if you haven’t filed taxes in a while, there are some things you need to know about what happens next.
You can go back and file for previous years, but you will be penalized. You will be charged compound daily interest starting May 1st of the first year you missed paying taxes. This rate might change every three months depending on prescribed interest rates.
However, if you continue not to file taxes at all, the government won’t help you out down the road. You won’t receive any benefits from programs like Old Age Security or Employment Insurance because these programs require proof that someone’s income is being taxed in order for them to collect their benefits.
Let’s get into it:

Do You Have to File a Tax Return Every Year?
Technically, you are not explicitly required to file a T1 Income Tax and Benefit Return every year if you meet all of the following conditions:
- You have no tax owing to the CRA.
- You do not want to claim a refund or tax credits.
- The CRA has not issued a formal demand for you to file.
However, even if you owe zero dollars, failing to file means missing out on vital government benefits, refundable credits, and building your RRSP contribution room. In practice, almost every Canadian resident should file annually.
What Are the Canadian Tax-Filing Deadlines?
Deadline for Most Individuals
For most Canadian residents, the annual personal income tax filing deadline is April 30 of every year.
For the 2025 tax year (filed in 2026), because April 30, 2026, falls on a Thursday, your tax return must be filed on or before April 30, 2026.
Deadline for Self-Employed Individuals
If you or your spouse/common-law partner were self-employed or operated a small business during the tax year, your tax filing deadline is extended to June 15.
For the 2025 tax year, June 15, 2026, falls on a Monday, making June 15, 2026, the official filing deadline for self-employed individuals.
How Long Do You Have to Pay Taxes in Canada?
Filing Deadline vs. Payment Deadline
It is crucial to distinguish between the filing deadline and the payment deadline.
Even though self-employed individuals have until June 15 to submit their tax returns, ALL tax balances owing for any individual must be paid by April 30, 2026. If you owe money, interest begins accruing on May 1, regardless of whether you have an extended filing deadline.
What to Do If You Cannot Pay on Time
If you cannot pay your full balance by the deadline, file your tax return on time anyway. Filing on time prevents the late-filing penalty, leaving you with only the balance owing and prescribed interest. You can set up a formal Payment Arrangement with the CRA to pay off your tax liability in manageable installments.

What Happens If You File Your Taxes Late?
Late-Filing Penalties
If you owe money and file late, the CRA applies a mandatory late-filing penalty:
- Initial Penalty: 5% of your balance owing on the deadline date.
- Additional Monthly Penalty: 1% of your balance owing for each full month the return is late, up to a maximum of 12 months.
- Repeated Late-Filing Penalty: If the CRA previously charged you a late-filing penalty for any of the 3 preceding tax years (2022, 2023, or 2024), your late-filing penalty doubles to 10% of your balance owing, plus 2% for each full month late (up to a maximum of 20 months).
Interest on Unpaid Taxes
In addition to penalties, the CRA charges compound daily interest on all unpaid balances. The CCRA’s prescribed interest rate for overdue taxes is updated quarterly. For Q1/Q2 2026, the prescribed interest rate for overdue tax balances stands at 9% (compound daily interest).
Delayed Benefits and Refunds
Missing filing deadlines directly halts income-tested benefit payments, including:
- Goods and Services Tax / Harmonized Sales Tax (GST/HST) Credit
- Canada Child Benefit (CCB)
- Guaranteed Income Supplement (GIS) or Old Age Security (OAS) top-ups
How Long Can You Legally Go Without Filing Taxes?
There is no legal grace period that permits you to skip filing if you owe tax. You are legally obligated to file on or before the statutory deadline for every tax year in which tax is payable.
While the CRA generally audits or reassesses returns within a 3-year normal reassessment period, there is no statute of limitations on unfiled tax returns or tax fraud. The CRA can legally require you to file and assess tax, penalties, and interest going back as far as records exist.
What Happens If You Have Not Filed for Several Years?
CRA Demands to File
If you fall behind by multiple years, the CRA’s automated tracking system will issue formal requests and statutory Demands to File. Ignoring these notices escalates enforcement actions.
Estimated Tax Assessments
If you ignore a Demand to File, the CRA may perform an Arbitrary Assessment (Section 152(7) Assessment). The CRA estimates your income based on third-party slips (T4, T5) without giving you credit for eligible deductions, write-offs, or business expenses, resulting in a significantly higher tax bill.
CRA Collection Actions
Unpaid assessments result in enforcement measures, including:
- Wage garnishments directly from your employer.
- Freezing bank accounts.
- Placing registered liens on real property.
Can You Go to Jail for Not Filing Taxes?
Late Filing vs. Tax Evasion
Filing late or being unable to pay your tax bill is a civil matter and will not result in jail time on its own. However, deliberately refusing to file after receiving formal CRA orders or committing tax evasion (willfully concealing income or fabricating expenses) is a criminal offence under Section 238/239 of the Income Tax Act. Prosecution can lead to fines between 50% and 200% of the tax evaded and potential imprisonment for up to 5 years.
How Far Back Can You File Tax Returns?
Filing Older Returns
You can file tax returns for previous years at any point. However, the CRA’s taxpayer relief and processing systems observe a strict statutory limit.
Under the CRA’s 10-Year Rule, the CRA only has the authority to process taxpayer relief requests, refund claims, and credit adjustments for returns within the past 10 calendar years. In 2026, the oldest tax year you can file to claim a refund or request penalty relief is the 2016 tax year.
Claiming Refunds From Previous Years
If you are owed a refund for a tax year older than 10 years (e.g., 2015 or earlier), the CRA is no longer required to issue the refund payment to you.
How to File Taxes When Records Are Missing
Finding Old Tax Slips
You can retrieve lost tax documents (such as T4, T5, or T3 slips) through:
- Your CRA My Account portal under “Tax Information Slips (T4 and more).”
- Contacting the CRA Individual Enquiries line.
- Requesting duplicate copies from past employers or financial institutions.
Reconstructing Income and Expenses
If documents are completely unavailable, you can reconstruct records using bank statements, credit card records, invoice books, or vendor receipts. An experienced accounting firm can help synthesize incomplete records into acceptable schedules.
What If You Have Unreported Self-Employment Income
Reporting Business Revenue
All gross income earned from freelancing, sole proprietorships, or gig platforms must be declared. Omitting income leads to gross negligence penalties (up to 50% of the understated tax).
Reviewing GST/HST Obligations
If your gross taxable revenues exceeded $30,000 across four consecutive calendar quarters, you were required to register for, collect, and remit GST/HST. Failing to collect GST/HST from clients does not relieve you of the obligation to pay it to the CRA out of pocket.

What Is the CRA Voluntary Disclosures Program?
When a Disclosure May Qualify
The Voluntary Disclosures Program (VDP) offers taxpayers a chance to correct inaccurate returns or file overdue returns before the CRA takes enforcement action. To qualify, an application must:
- Be voluntary (submitted before the CRA initiates an audit or enforcement contact regarding the issue).
- Be complete and accurate.
- Involve a penalty-applicable situation.
- Include information that is at least one year old.
Possible Penalty and Interest Relief
Under the VDP’s General Program, qualifying taxpayers receive:
- Full relief from criminal prosecution.
- Waiver of 100% of late-filing penalties.
- Partial interest relief (typically a 50% reduction in interest charges for back years).
How to Catch Up on Unfiled Taxes
Confirm Which Returns Are Missing
Contact the CRA or review your CRA My Account to determine the precise tax years listed as outstanding.
Gather Tax Documents
Collect all relevant income slips, receipts, logbooks, and deductions for each outstanding year.
File Returns in the Correct Order
Prepare and submit tax returns in chronological order. This ensures carried-forward amounts (such as unused RRSP contributions, tuition credits, or capital losses) apply accurately to subsequent years.
Arrange Payment With the CRA
Once assessments are issued, pay balances in full or establish a payment arrangement with CRA collections to prevent garnishment.
Can the CRA Waive Penalties or Interest?
Yes. Under Taxpayer Relief Provisions, the CRA may cancel or waive penalties and interest if extraordinary circumstances prevented you from meeting your tax obligations, such as:
- Severe illness, injury, or emotional distress.
- Natural disasters (e.g., floods, fires).
- Severe CRA processing delays or errors.
Relief requests must be submitted within 10 years of the end of the calendar year in which the tax year occurred (e.g., a request for the 2016 tax year must be submitted by December 31, 2026).
Common Mistakes When Filing Old Tax Returns
- Filing Out of Order: Submitting newer years before older years leads to incorrect carried-forward credit calculations.
- Using Current-Year Rules for Past Years: Tax rates, brackets, and credits change annually. Always use the tax forms and rules specific to the year being filed.
- Ignoring GST/HST Duties: Small business owners frequently file overdue T1 returns while forgetting corresponding GST/HST returns.
- Waiting for the CRA to Call: Waiting until the CRA contacts you eliminates your eligibility for the Voluntary Disclosures Program.
When to Hire an Accountant for Unfiled Taxes

Frequently Asked Questions About Unfiled Taxes
Can I File Several Years at Once?
Yes. You can prepare and submit tax returns for multiple years simultaneously. Ensure they are submitted chronologically so carry-forward credits are correctly applied.
Will I Be Penalized If I Do Not Owe Tax?
No. The standard late-filing penalty is calculated as a percentage of the balance owing. If you are owed a refund or have a zero balance, no late-filing penalties or interest will apply.
Can I Receive Benefits After Filing Old Returns?
Yes. Once your old tax returns are processed, the CRA will retroactively calculate and disburse any withheld benefits (such as CCB or GST/HST credits) up to the 10-year statutory limit.
What Should I Do If I Cannot Pay?
File your return on time to avoid the 5%+ late-filing penalty, then contact the CRA immediately to establish a workable payment plan based on your financial capacity.
