Failure to Report Income in Canada: Penalties, Fixes & Legal Options

Quick Answer – What To Do First

• Don’t file a brand-new return. Correct the original one.
• Use Change my return / ReFILE online first (fastest).
• If the CRA has already contacted you, consider Taxpayer Relief (RC4288).
• For larger or multiple errors, think about the Voluntary Disclosures Program (VDP).

What Does “Failure to Report Income” Mean in Canada?

This occurs when taxable income such as employment earnings, rental income, gig or contract work, crypto gains, or foreign earnings is left off your return. Even unintentional mistakes can trigger penalties, interest, and CRA audits.

What Penalties Could You Face?

Repeated Failure to Report Income Penalty (ITA s.163(1))
This applies if you failed to report $500 or more in income this year and in any of the previous three years.

The penalty is the lesser of:

• 10% of the unreported amount (federal + provincial/territorial), or
• 50% of the difference between understated tax/overstated credits and the tax withheld.

Quebec residents typically pay only the federal penalty; non/deemed residents may be exempt provincially.

Gross Negligence Penalty
Applies when the CRA proves you knowingly or with gross negligence made a false statement or omission.

• Penalty is the greater of $100 or 50% of understated tax/overstated credits.

How to Fix Unreported Income

1. Change My Return / ReFILE (online)

   • Best for small mistakes like a missed T4 or T5.
   • Processing is usually about 2 weeks.

2. T1 Adjustment Request (paper)

   • Used if online services don’t work.
   • Much slower — can take months.

3. Voluntary Disclosures Program (VDP)

   • Best for multiple or significant unreported amounts.
   • Must be submitted before CRA contacts you.
   • May provide penalty relief, protection from prosecution, and partial interest relief.

4. Taxpayer Relief (Form RC4288)

   • Available if penalties and interest have already been assessed.
   • Can be applied up to 10 years back.
   • Current processing times: 6–8 months.
