The penalties, CRA’s process, and how to bounce back without losing sleep.
Let’s be honest — nobody plans to file a late tax return.
Maybe you were swamped with clients. Maybe your bookkeeping was behind. Or perhaps the tax season just slipped past you.
Now it’s after the original filing deadline, and you’re asking:
“Am I in serious trouble with the CRA?”
Take a deep breath. You’re not the first business owner to miss a filing obligation — and you won’t be the last. What matters is what you do next.
This guide breaks it down in plain English:
- What happens when you file late vs pay late in Canada
- How the CRA calculates penalties and interest
- When the CRA might take enforcement action
- What steps do I take now to reduce penalties and stress
- Special programs for late or incorrect tax returns
Late-Filing Penalties vs. Late Payment Penalties
In Canada, there are two corporate tax deadlines to consider:
- Corporate tax payment deadline (3 months after your year-end)
- Corporate tax filing deadline (6 months after your year-end)
Missing either has its consequences—but they’re different.
Late Payment Penalties
Even if you file your corporation income tax return on time, failing to pay your taxes on time triggers interest.
CRA charges compound daily interest on the unpaid balance.
The prescribed interest rate is set quarterly and typically ranges between 7–10% annually.
Key point: Unlike late-filing penalties, there’s no cap on interest—it keeps compounding until the full balance is paid.
Example: If you owe $10,000 and delay payment by 90 days with a 9% interest rate:
- Daily interest: 0.0247%
- Interest: 0.0247% × 90 × $10,000 ≈ $222
Late-Filing Penalties
If you owe a balance of tax and file late, the CRA charges a late-filing penalty:
- 5% of your unpaid balance, plus
- 1% per full additional month late, up to a maximum penalty of 12 months
That adds up to a potential 17% applicable base penalty rate for first-time late filers.
Example: If you owe $10,000 and file 3 months late:
- 5% of $10,000 = $500 (base penalty)
- 1% × 3 months = $300
- Total penalty: $800
And that’s before additional interest charges or late penalties…
Interest Charges on Late Taxes (Updated Quarterly)
The CRA charges compound daily interest on:
- Unpaid taxes
- Late-filing penalties
- Previous tax debt
As of Q2 2025, the prescribed interest rate is 8% per annum.
How Interest Accumulates:
- Calculated and compounded daily
- No penalty-free program or maximum limit
Example: Delay payment by 90 days at 8%:
- Daily interest = 0.0219%
- 90-day penalty interest: $197.10
Repeat Offender - Penalties Double
If you’ve had late tax returns before, the CRA increases your penalty for failure to file.
You’re considered a repeat offender if:
- You were assessed a late-filing penalty in the past 3 years
- You received a legal warning letter (formal demand) for this year
In that case:
- 10% base penalty, plus
- 2% per full or partial month late, up to 20 months
Over time, you could face excessive penalties of up to 50%.
Will the CRA Come After You?
Short answer: Yes — eventually. CRA uses automation to detect:
- Late returns for incorporated businesses
- Missing GST/HST remittance on time
- Unfiled payroll remittances
If flagged, the CRA may:
- Issue a substitute return (usually overestimated)
- Freeze your account with financial institutions
- Garnish income and benefit payments
- File liens
Important: Filing (even late) and contacting CRA is better than silence.
