Penalties for Late Filing Personal Returns in 2026: What ITA s.162 Actually Says

You meant to file on time.
You were waiting on a slip.
You assumed there would be no penalty because “no tax is owing.”

Then the Notice of Assessment arrives — with penalties and interest.

Under Income Tax Act (ITA) s.162, late filing penalties are statutory. They are not discretionary.

If a return is filed late and tax is owing, the penalty formula applies automatically.

Let us examine how this works — and when it becomes severe.

 

First Principle: Filing Deadline for Individuals

For most individuals:

• Filing deadline: April 30
• If self-employed (or spouse/common-law partner is self-employed): June 15
• However, any tax owing is due April 30

Filing after the applicable deadline may trigger penalties under s.162(1).

 

The Basic Late Filing Penalty (ITA s.162(1))

If you file late and have a balance owing:

The penalty is:

5% of the unpaid tax owing,
PLUS
1% of the unpaid tax for each full month late,
up to a maximum of 12 months.

This means:

Maximum basic penalty = 5% + 12% = 17% of unpaid tax

Interest is charged separately.

 

Example Scenario

Tax owing: $20,000
Filed 6 months late

Penalty calculation:

• 5% × $20,000 = $1,000
• 1% × $20,000 × 6 months = $1,200

Total penalty = $2,200

Interest is charged on both tax and penalty.

 

Repeat Failure to File (ITA s.162(2))

If CRA issued a late-filing penalty in any of the previous three taxation years:

The penalty increases significantly.

Repeat penalty:

10% of unpaid tax,
PLUS
2% per month, up to 20 months.

Maximum repeat penalty = 10% + 40% = 50% of unpaid tax

This is not minor.

 

Example: Repeat Offender

Tax owing: $50,000
Filed 8 months late
Prior late-filing penalty within 3 years

Penalty:

• 10% × $50,000 = $5,000
• 2% × $50,000 × 8 months = $8,000

Total penalty = $13,000

Plus interest.

Statutory exposure becomes material.

 

What If No Tax Is Owing?

If you are in a refund position:

The standard late filing penalty under s.162(1) generally does not apply.

However:

Other penalties may apply if:

• You failed to report income
• You were required to file specific information returns
• You are subject to special reporting rules

Filing remains important.

 

Interest Is Separate

Interest is not a penalty.

Interest:

• Applies to unpaid tax from the balance due date
• Applies to penalties once assessed
• Compounds daily

Interest continues until full payment.

 

Failure to Report Income Penalty (ITA s.163(1))

Separate from late filing:

If you fail to report income in the current year and did so in one of the prior three years:

A penalty may apply equal to:

10% of the unreported income (federal),
plus potential provincial equivalent.

This is distinct from late filing penalties.

 

Gross Negligence Penalty (ITA s.163(2))

If CRA determines:

• You knowingly or under circumstances amounting to gross negligence made a false statement or omission,

Penalty may be:

50% of understated tax.

This is significantly more serious than simple late filing.

 

Voluntary Disclosures Program (VDP)

If you have not filed returns:

You may apply under CRA’s Voluntary Disclosures Program.

If accepted:

• Penalties may be waived
• Partial interest relief may apply

But timing is critical.

Once CRA initiates enforcement, VDP may not be available.

 

Self-Employed Individuals

Self-employed taxpayers often misunderstand:

While filing deadline is June 15, any tax owing is due April 30.

Interest begins accruing after April 30 — even if filing by June 15.

Late filing beyond June 15 triggers s.162 penalties.

 

Family-Owned Enterprise Considerations

Owner-managers often:

• Defer filing pending corporate returns
• Delay personal reporting of dividends
• Wait for K-1 or foreign income slips

Late filing penalties apply regardless of business complexity.

Integrated planning ensures timely personal compliance.

 

Common Misunderstandings

“If I can’t pay, I shouldn’t file.”
File on time even if you cannot pay. Penalties apply only to unpaid tax — but filing reduces exposure.

“CRA will waive it automatically.”
Penalties are statutory under s.162.

“It’s only a small percentage.”
Repeat penalties can reach 50% of unpaid tax.

“I’ll wait until everything is perfect.”
Reasonable estimates are better than late filing.

 

Strategic Planning for 2026

Before deadline:

• File on time — even if payment plan needed
• Estimate missing slips if necessary
• Monitor repeat-filing exposure
• Coordinate personal and corporate filings
• Consider VDP if prior years missing

Tax compliance is not optional — but penalties are avoidable.

 

Final Thoughts

Under ITA s.162, late filing penalties are formula-driven and automatic when tax is owing.

The standard penalty is 5% plus 1% per month.

Repeat penalties escalate to 50% of unpaid tax.

Interest compounds separately.

For disciplined families and entrepreneurial professionals, filing on time is not merely administrative — it is financial risk management.
