Yes, you can file your self-employed taxes late in Canada — the CRA will accept a return filed after the June 15 deadline. But filing late with a balance owing triggers penalties and interest that compound quickly. Here is exactly what happens and how to handle it.
The Deadlines Recap
- April 30: Pay any balance owing — interest starts May 1 regardless of when you file
- June 15: File your T1 return (extended deadline for self-employed and their spouses) — filing after this triggers the late-filing penalty
What Happens If You File After June 15 With a Balance Owing
Late-filing penalty: 5% of your balance owing on June 15, plus 1% for each additional full month the return remains unfiled, up to 12 months maximum.
Examples with a $5,000 balance owing:
- Filed July 15 (1 month late): $300 penalty (6%)
- Filed August 15 (2 months late): $350 penalty (7%)
- Filed September 15 (3 months late): $400 penalty (8%)
- Filed after June 15 the following year (12 months late): $850 penalty (17% maximum)
Repeat offenders penalized in any of the 3 prior years who received a formal demand: 10% base + 2% per month, up to 20 months.
Interest: On top of any penalty, the CRA charges daily compound interest at ~7–8% on the unpaid balance from May 1. If you file June 16 with a $5,000 balance unpaid since May 1, you already owe 46 days of interest before the late-filing penalty applies.
What Happens If You File After June 15 With No Balance Owing
No late-filing penalty — the penalty is calculated on the balance owing. If you are owed a refund or have zero owing, there is no financial penalty for late filing. However:
- Your refund is delayed until the return is processed
- Canada Child Benefit, GST/HST credit, Ontario Trillium Benefit, and other benefits that depend on your filed return may be paused
- Once you file, the CRA recalculates and issues catch-up payments for months missed
Multiple Unfiled Years: What to Do
If you have missed 2 or more years of filing, the CRA’s Voluntary Disclosures Program (VDP) may provide relief:
- You come forward before the CRA contacts you about the unfiled returns
- The CRA may waive all penalties and reduce interest by up to 50%
- You still pay the original tax owing, but without the compounding penalties
- File using Form RC199 — a CPA experienced with VDP submissions can help
The Golden Rule: File Even If You Can’t Pay
If April 30 passes and you cannot pay your balance, file your return by June 15 regardless. The late-filing penalty is far more damaging than the interest on unpaid balance:
- Interest on $5,000 unpaid for 2 months at 7%: approximately $58
- Late-filing penalty on $5,000 for 2 months: $350
File on time. Contact CRA to arrange a payment plan for the balance. The CRA’s Debt Management Call Centre (1-888-863-8657) handles payment arrangements and can set up monthly payments or short-term deferrals.
Frequently Asked Questions
Is there any grace period after June 15?
No formal grace period exists. One day after June 15 is officially late. However, if June 15 falls on a weekend or public holiday, the deadline shifts to the next business day — check the CRA website for the current year’s exact date.
Can I request a deadline extension from the CRA?
The CRA does not grant individual tax filing extensions. The extended June 15 deadline for self-employed is the only extended deadline available. If extraordinary circumstances (illness, disaster) prevented you from filing, you can apply for penalty and interest relief after the fact through Form RC4288 — but this does not pre-approve late filing.
Will filing late affect my credit score?
Not directly — CRA tax debts do not automatically appear on credit reports. However, if the CRA pursues collection and registers a lien against your property (for significant, long-outstanding debts), this may affect your ability to sell or refinance. For modest balances, collections typically involve payment demands before legal action.
