I contributed too much to my RRSP. How do I fix it?

Arsen Accounting Services · T1 guide · Sources checked October 29, 2026

Start by checking the contribution dates and your actual available room. If an excess exists, correcting the balance and dealing with any excess-contribution tax are separate tasks. Filing your ordinary T1 return alone may not resolve both. CRA: RRSP excess contributions

Reconcile the numbers before moving money

Your RRSP deduction limit, contributions already made but not deducted, and remaining room are different figures. CRA bases the deduction limit partly on the previous year’s earned income and pension adjustments. Compare the latest assessment with records from every RRSP provider, including contributions to a spouse’s plan that you made. CRA: RRSP definitions and deduction limits

Prepare a month-by-month list rather than relying only on the total printed on an annual receipt. Include payroll contributions, employer deposits where applicable, transfers and withdrawals as separate entries. Flag any transaction you are unsure how to classify so it is reviewed before you take action.

The $2,000 cushion is not another deduction

Subject to its eligibility rules, the usual $2,000 cushion can prevent some excess amounts from attracting the monthly tax. It does not increase your RRSP deduction limit. Generally, unused contributions more than $2,000 above the limit attract 1% tax per month. Do not treat the cushion as a reason to make further deposits.

Check the withdrawal paperwork

Unused contributions can sometimes be withdrawn with an offsetting deduction, but conditions and timing matter. CRA’s process may involve Form T3012A before withdrawal or Form T746 when preparing the return. A routine withdrawal is not automatically a tax-free correction. Confirm the route that fits your contribution history. CRA: Withdrawing unused RRSP contributions

If CRA has approved the applicable T3012A, the issuer can refund the qualifying unused contributions without withholding. Without that approval, withholding generally applies. The resulting T4RSP slip still needs to be handled correctly on your return; withholding is distinct from the monthly excess tax. CRA: T4RSP refunds and withdrawals

Address the separate return and possible relief

When excess-contribution tax is payable, CRA generally requires the applicable T1-OVP return and payment within 90 days after the calendar year ends. Exact transaction months matter. A request to waive or cancel this tax requires a reasonable error and reasonable steps to eliminate the excess; approval is not automatic. CRA: RRSP excess contributions

What to gather now

• Your latest assessment and RRSP deduction-limit statement.
• Contribution and withdrawal dates from every institution.
• Prior returns showing contributions carried forward without a deduction.
• Group-plan or payroll contribution details.
• Any CRA letter, excess-tax assessment or previous correction forms.

Common questions

Can I simply claim the extra contribution next year?

A future deduction does not by itself settle a tax that arose from an earlier monthly excess. Review the contribution timeline. CRA: RRSP excess contributions

Should I withdraw before checking the amount?

Act promptly, but first reconcile what is actually excess and which withdrawal process applies. Keep the institution’s transaction confirmation for the review.
