TFSA Overcontribution: How to Fix It Before the CRA Penalty Hits Your Account
A single $5,000 mistake in February can cost you $600 by December. The Tax-Free Savings Account penalty structure doesn't care about intent, and the 1% monthly tax starts the moment your balance crosses the contribution ceiling. Most people discover the problem in July when the CRA letter arrives, after five months of penalties have already accumulated.
Here's exactly what to do the moment you realize you've put too much into your TFSA.
Withdraw the Excess Immediately
Do not wait for the CRA letter. Do not hope the system "fixes itself" when January rolls around. The penalty clock runs every month the excess sits in the account, and waiting costs $10 per month for every $1,000 over the limit. Withdraw the full excess amount the same week you catch the mistake. This stops the bleeding.
The withdrawal itself does not restore contribution room in 2026. That room comes back on January 1st, 2027. But removing the money immediately caps the penalty at however many months have already passed. A $3,000 overcontribution discovered in March and withdrawn in March costs $30 in penalties. The same mistake withdrawn in September costs $180.
Track What the CRA Actually Knows
Log into your CRA My Account portal. The "TFSA contribution room" figure you see reflects data as of January 1st, 2026. It does not update in real time when you make deposits or withdrawals during the current year. Financial institutions report TFSA transactions to the CRA once annually, usually by the end of February.
This lag is the reason most overcontributions go unnoticed until mid-year. You deposited $7,000 in January, withdrew $4,000 in March, then redeposited $6,000 in April because you thought the withdrawal created new room. It didn't. The $6,000 in April is a $3,000 overcontribution if you started the year with only $7,000 in available room.
Keep your own spreadsheet. The portal is a starting point, not a live balance.
Calculate the Penalty Before the CRA Does
The penalty is 1% per month on the highest excess amount that existed in any month. If you overcontributed by $8,000 in February, then withdrew $3,000 in March, the penalty for February is $80. The penalty for March is $50 (1% of the remaining $5,000). The penalty for April onward depends on whether you pulled the rest out or left it sitting.
The CRA sends Form RC243-P (Proposed Tax Return for TFSA) listing the penalty amount they've calculated. You have 90 days from the date on the form to either pay or dispute it. Ignoring the form does not make it disappear.
Request Relief Only If You Have a Case
The CRA can waive the penalty under their Taxpayer Relief provisions if the overcontribution resulted from a "reasonable error" and you removed the excess "without delay." Reasonable means you misunderstood a specific rule, not that you didn't know the rules existed. Without delay means you withdrew the money the moment you became aware, not three months later.
Write a letter to your tax services office explaining what happened, when you discovered it, and when you withdrew the excess. Attach evidence: account statements, the withdrawal confirmation, anything showing you acted immediately upon learning about the mistake. Submit it with Form RC4288 (Request for Taxpayer Relief). Approval is discretionary. The CRA grants relief in cases involving direct transfers that were mishandled by financial institutions, or where their own My Account portal showed incorrect room figures that you relied on.
They do not grant relief for re-contribution traps, where you withdrew money in April and put it back in June assuming the room regenerated mid-year.
Avoid the Second Mistake
The most expensive error is treating the TFSA like a chequing account. Every in-and-out cycle creates tracking complexity and increases the odds of a math error. If you need liquidity, keep that money in a high-interest savings account outside the TFSA structure. The account is for money that stays put, not for short-term cash management.
If you're transferring a TFSA from one bank to another, the institutions must execute the move as a "qualifying transfer" on their end. Withdrawing the cash yourself and depositing it at the new bank counts as a withdrawal and a new contribution, which consumes your annual room twice. Request the transfer form. Pay the fee if the old bank charges one.
The penalty is avoidable. The correction is mechanical. Act fast, document everything, and stop using the account as a parking spot for next month's rent.
