Can CRA waive my TFSA overcontribution penalty if it was an honest mistake?
Yes, it can. Under subsection 207.06(1) of the Income Tax Act, the CRA has the discretion to waive or cancel all or part of the 1%-per-month tax on excess TFSA contributions β but only if the tax arose because of a reasonable error and you arranged to have the excess withdrawn without delay. The relief is not automatic: you have to write a detailed letter to the CRA's TFSA Processing Unit explaining what happened and why waiving the tax would be fair, and you still have to file Form RC243 and pay the tax first β a granted cancellation is then refunded.
The two conditions, unpacked
| Condition | What it means in practice |
|---|---|
| Reasonable error | A genuine misunderstanding or an error a reasonable person could make β for example, misreading the recontribution rule, relying on wrong information from a bank, or a duplicate contribution caused by an institution's mistake. Simply ignoring your limits or hoping CRA will not notice does not qualify. |
| Withdrawn without delay | You removed the excess (or arranged to) promptly once you knew about it. CRA looks at the timeline: how long the excess sat in the account after you became aware of it. |
CRA reviews each request case by case on its own facts. A prompt correction after discovering the error is consistently described as one of the strongest factors in your favour.
How to apply, step by step
- Withdraw the excess amount first. This stops the 1% monthly tax from growing and satisfies the "without delay" condition.
- File Form RC243 (TFSA Return) and pay the tax owing. The return is due by June 30 of the year after the overcontribution occurred. CRA assesses the tax first β relief, if granted, comes after.
- Write a detailed letter explaining why the tax liability arose and why it would be fair to cancel or waive all or part of it. Include a clear timeline, account statements showing the contributions and withdrawals, your TFSA room records, and any CRA correspondence about the excess. There is no prescribed CRA form for TFSA waivers β a letter is the format.
- Send it to the TFSA Processing Unit at one of these addresses, or submit it through the "Submit documents" service in CRA My Account:
Canada Revenue Agency β TFSA Processing Unit, Sudbury Tax Centre, PO Box 20000, Station A, Sudbury ON P3A 5C1
or
Canada Revenue Agency β TFSA Processing Unit, Winnipeg Tax Centre, PO Box 14000, Station Main, Winnipeg MB R3C 3M2
- Wait for CRA's decision letter. CRA will review the request and send you a letter explaining its decision. If you disagree with an assessment, you can file a formal objection (Form T400A) within 90 days β CRA itself recommends requesting the waiver first.
Important nuances
- Waiver vs cancellation: CRA defines a "waiver" as relief granted before the tax is assessed and a "cancellation" as relief from amounts already assessed. In practice, you usually pay first and get a refund if relief is granted.
- The relief only covers Part XI.01 tax β the 1%-per-month excess tax. It does not cover other penalties or taxes.
- If a waiver is granted, you may also have to withdraw any income or gains attributable to the excess, and those withdrawn amounts are included in your taxable income for the year.
- Not automatic and not guaranteed. Asking does not mean receiving β CRA exercises its discretion, and if it refuses, your recourse is the objection process and ultimately the Federal Court, which reviews whether CRA's decision was reasonable.
Frequently asked questions
Should I apply before or after CRA assesses me?
Either. You can send the letter as soon as you discover the error β you do not have to wait for a notice of assessment. But do not skip filing RC243 and paying: an unfiled return or unpaid tax weakens the request.
Does paying the tax first hurt my chances?
No β it is the expected sequence. CRA assesses the tax on the filed return, and a granted cancellation refunds it. Paying promptly also stops interest from accruing on the assessed amount.
What if the overcontribution was my bank's fault?
An institution's processing error β for example, a contribution processed twice because the first phone call was not recorded β is a classic reasonable-error scenario. Include the bank's confirmation of the error with your letter; it is some of the strongest supporting evidence you can provide.
