If you missed the April 30, 2026 filing deadline (or your June 15, 2026 self-employed deadline), you’re not alone. Whether you needed more time to gather slips, you’re self-employed and still sorting business records, or your corporation is behind on its T2, what matters now is filing as soon as you can, paying what you can, and understanding how late-filing penalties and interest are calculated.
This guide walks through what happens when you file late, how to catch up for individuals and corporations, and when to get professional help. For key dates before you’re behind, see Tax Filing Deadline Canada: Key Dates and Checklist for 2026 (Personal and Corporate).

What Happens If You File After the Deadline?
Individuals (T1)
If you owe tax and file after the deadline, the CRA generally charges a late-filing penalty:
- 5% of your balance owing, plus
- 1% of the balance owing for each full month the return is late, up to 12 months
Example: If you file three months after the deadline, the late-filing penalty is typically 8% of the balance owing (5%base + 1% × 3 months).
If this is not your first time filing late, and the CRA issued a demand to file in one of the previous three years, the penalty can increase to:
- 10% of the balance owing, plus
- 2% per full month, up to 20 months
Interest is separate from the late-filing penalty. The CRA charges compound interest daily on unpaid balances starting the day after the balance-due date. For most individuals, that is May 1 (the day after April 30, 2026). If you’re self-employed and your return is not due until June 15, 2026, interest on any tax owing still starts from the balance-due date, not from June 15.
Filing on time even when you can’t pay in full avoids the late-filing penalty (interest still applies to amounts owed). For a concise overview, see Filing Taxes Late: Potential Penalties.
Corporations (T2)
For T2 returns with tax owing, the CRA typically charges a late-filing penalty of 5% of the unpaid tax plus 1% per full month the return is late, up to 12 months. Repeat late filers who received a demand to file in a prior year can face higher rates, similar to the individual rules. Interest compounds daily on balances not paid by the due date.
Corporate payment is generally due two months after year-end (or three months for certain CCPCs), while the T2 return is due six months after year-end. Payment and filing deadlines are not the same date, and missing either can be costly. See Corporate Tax Filing Deadlines in Canada: Key Dates and Checklist for 2026 for the full corporate calendar.
Steps to File Late and Minimize Penalties (Individuals)
File as soon as you can, even if you can’t pay in full
The CRA stops the late-filing penalty clock when your return is filed. Waiting “until you have the money” usually makes the problem worse. File first, then work out payment.
Pay what you can to reduce interest
Interest applies to whatever balance remains unpaid. Every dollar you pay reduces the amount interest is calculated on, so even a partial payment helps.
Set up a payment arrangement if needed
If you can’t pay the full balance, the CRA offers payment arrangements (instalments over time). Contact the CRA or use their online options. For RHN resources on paying tax, see Make Income Tax Payments.
Correct prior-year errors
If you filed but made a mistake, or need to report income you omitted, use a T1 Adjustment or other correction process. For guidance, see Correct Your Taxes. In serious cases (unreported income over multiple years, offshore issues), ask whether a voluntary disclosure or specialized program applies before the CRA contacts you.
Filing Late for Corporations and Businesses
If your corporation missed its T2 deadline or has an unpaid balance:
- Complete and file the T2 as soon as possible
- Reconcile instalments paid versus tax owing
- Pay the balance or request a payment arrangement
- Confirm T4, T5, T3, and other information returns are filed. Each has its own penalties.
Corporate filings are harder to fix casually when shareholder loans, intercompany transactions, or multi-year arrears are involved. Large balances, several years behind, CRA notices or audits, and complex structures (trusts, partnerships, multiple provinces) are all good reasons to get professional help before you file.
Do You Still Get Benefits and Refunds?
Yes, but you must file to receive them.
- Refunds: The CRA does not charge a late-filing penalty when no tax is owing (e.g. you are due a refund). You still should file; refunds can be held or delayed if you are behind on other filings.
- Benefits and credits (GST/HST credit, Canada Child Benefit, BC credits, etc.) often depend on filing your return. Late filing can interrupt or delay benefit payments.
If you are owed money or rely on benefits, filing late is still worth doing, so file as soon as you can.
When to Get Professional Help
Consider speaking with an accountant if:
- You owe a large balance or several years are unfiled
- You’re self-employed and behind on GST/HST, instalments, or source deductions
- You received a CRA notice, audit letter, or demand to file
- You’re a corporation with complex accounts or multi-year arrears
- You’re unsure whether to use an adjustment, payment plan, or voluntary disclosure
If your situation is complicated, a quick conversation with an accountant can clarify your options before the CRA escalates.
FAQ
How do I file my taxes late?
Prepare your return (or have it prepared), file it with the CRA as soon as possible online, through a representative, or by paper where allowed, and pay what you can. If you can’t pay in full, contact the CRA about a payment arrangement. For prior-year mistakes, see Correct Your Taxes.
What are the penalties for filing late?
If you owe tax, the CRA typically charges 5% of the balance owing plus 1% per full month (up to 12 months). Repeat late filers who received a demand to file in a prior year may face 10% plus 2% per month (up to 20 months). Interest is charged separately on unpaid amounts.
Does filing late affect my refund?
There is no late-filing penalty when you have no tax owing and are due a refund, but you still need to file to receive the refund and to keep benefits and credits flowing.
What if my corporation filed late?
File the T2 immediately, pay or arrange payment, and address any missing T4, T5, or T3 slips. Corporate penalties and interest apply to unpaid corporate tax.
Next Steps
Filing late is fixable. The worst outcome is usually not filing at all. Penalties and interest keep growing, and CRA contact becomes harder to manage the longer you wait.
File your return now, pay what you can, and arrange the rest if you need to. If you run a corporation, get the T2 filed, reconcile installments, and clean up any missing information returns.
