RRSP Over-Contribution Penalty Canada 2026: $2,000 Buffer, 1% Tax & How to Fix

Updated

RRSP over-contributions trigger a 1% monthly penalty on every dollar above your limit plus the $2,000 lifetime buffer — and the clock starts ticking immediately. A $10,000 over-contribution costs $80 per month until you fix it, and if you don’t file Form T1-OVP within 90 days of year-end, CRA can add late-filing penalties on top. The most common causes are pension adjustments you didn’t account for, employer group RRSP contributions, or confusion around Home Buyers’ Plan rules. The good news: if it’s a genuine mistake and you act fast, CRA will often waive the penalty entirely.

Checking Your Room

You can also use our RRSP contribution room calculator before making a large contribution.

CRA My Account is the only source you should trust for your exact contribution room. Your Notice of Assessment from last year’s tax return shows your room as of that date, but it doesn’t reflect contributions you’ve made since. Before making any RRSP contribution — especially a large lump sum near the deadline — log in and verify. If you have an employer group RRSP, remember that your employer’s matching contributions and any pension adjustments reduce your available room, often by more than you expect.

The Bottom Line

Check CRA My Account before every RRSP contribution, especially if you have an employer group plan or pension. If you discover an over-contribution, withdraw the excess immediately using Form T3012A for a tax-free withdrawal, file T1-OVP to report the penalty, and include a letter requesting relief if it was a genuine mistake. The $2,000 buffer exists for margin of error, not as a free contribution strategy — the complexity and risk of accidentally exceeding it aren’t worth the trivial extra growth on $2,000. | Employer over-contributed | Contact payroll | | Multiple employers | Track combined | | Catch-up contributions | Check room first |
