Fixing a TFSA Overcontribution Before It Grew Worse

The situation

Ifrah worked seasonally as a farm worker outside Ottawa, and her partner Yusuf worked as a security guard. Together they rented out a self-contained unit in the lower level of their home, and the rent had let them build up a modest cushion of savings over a few years. Neither of them had a financial background, and they managed their own accounts without help from an advisor.

A Tax-Free Savings Account, or TFSA, lets a person contribute money up to a limit set each year by the government, called contribution room. Room accumulates from the year a person turns eighteen, whether or not they open an account, and unused room carries forward indefinitely. Withdrawals from a TFSA are added back to a person's available room — but only starting the following calendar year, not immediately.

That timing rule was the part Ifrah and Yusuf did not know. Earlier in the year, Ifrah had withdrawn a portion of her TFSA to cover a car repair, then a few months later deposited a larger sum from the rental account back into the same TFSA, assuming the room she had withdrawn was available again right away. It was not. Because the withdrawn amount would not count as new room until the following January, her new deposit pushed her well past what she was actually entitled to contribute that year.

What the letter revealed

Several months later, Ifrah received a letter from the Canada Revenue Agency flagging an excess TFSA contribution and proposing a tax on the amount over her limit. The tax on an excess TFSA contribution is calculated for every month the excess remains in the account, so the longer it sits uncorrected, the larger the bill grows. By the time the letter arrived, months had already passed since the overcontribution occurred, and the tax owed on that stretch of time was not something a later fix could undo.

Ifrah and Yusuf came to us confused and worried, on the recommendation of Ifrah's brother Karim, who had gone through a smaller version of the same problem a few years earlier and knew it needed a fast response. They had not tried to game the system or squeeze out extra tax-sheltered growth — they had simply misunderstood how the withdrawal-and-recontribution timing worked, which is one of the most common ways ordinary savers stumble into an overcontribution. Their total excess, once we recalculated it against her actual contribution history, came to a little under $9,500. Combined with the monthly tax that had already accrued before they contacted us, their total exposure sat under $15,000, but every additional month of delay would only add to it.

Our first job was to establish exactly how much of the deposit was genuinely excess, since Ifrah's own estimate did not match the CRA's letter. We pulled her full TFSA contribution and withdrawal history and rebuilt her room year by year, confirming the CRA's figure was close to correct but slightly overstated because it had not yet accounted for a small amount of unused room carried forward from an earlier year.

What we did

1. Reconstructed the full contribution timeline. We gathered account statements going back to the year Ifrah opened her TFSA and matched every deposit and withdrawal against the room available at each point, rather than relying on the CRA's summary figure alone. This caught the small overstatement in the agency's calculation before it became the basis for the correction.
2. Directed an immediate withdrawal of the excess amount. The monthly tax on an excess contribution continues to accrue for as long as the excess sits in the account, so the single most important step was stopping the bleeding. We advised Ifrah to withdraw the excess portion right away, which she did within days, ending any further monthly tax from accruing going forward.
3. Filed the required form disclosing the excess contribution. A taxpayer who has overcontributed to a TFSA must file a specific form with the CRA reporting the excess and the tax owing for the period it remained in the account. We prepared and filed this on Ifrah's behalf, along with the corrected calculation showing the slightly lower true excess figure.
4. Prepared a request to waive the tax on reasonable grounds. The CRA can cancel or waive the tax on an excess TFSA contribution where the excess arose because of a reasonable error and the taxpayer acted without delay to fix it once they became aware of it. We drafted a written request explaining the withdrawal-timing mistake in plain terms, attaching proof that Ifrah had withdrawn the excess within days of learning about it, and asking that the tax accruing from that point forward be cancelled.
5. Advised on record-keeping going forward. We walked Ifrah and Yusuf through how to check their available contribution room before any future deposit, including the rule that a withdrawal does not free up room again until the calendar year after it happens, so the same mistake could not recur.

The outcome

The CRA's response, which took several months to arrive, was a partial success rather than a clean win — and that was the realistic outcome from the moment the letter first arrived. The agency accepted our waiver request for the tax that would otherwise have continued accruing after Ifrah's prompt withdrawal, so no further monthly tax was charged from that point forward. But the tax that had already accrued during the months before Ifrah knew about the problem — a little over $600 — was not cancelled. The CRA's position was that the waiver applies to tax that would otherwise continue to build, not to tax that has already crystallized for a period before the taxpayer took corrective action.

Ifrah paid that amount along with the recalculated (and slightly reduced) total once our corrected figures were accepted. It was not the outcome she had hoped for when she first called, but it was a genuine improvement on where things were heading. Left unaddressed, the excess would have kept accruing tax every month it remained in the account, and a written explanation filed months later — after further delay — would have had a much weaker case for any waiver at all. Acting immediately on the withdrawal was what made the later waiver argument credible.

For Ifrah and Yusuf, the lesson landed hardest on the point they had least expected: that withdrawing money from a TFSA does not restore your ability to recontribute it in the same year. It is one of the most counterintuitive features of an account that is otherwise marketed as flexible, and it catches savers at every income level, not just those with complex finances.
