You pulled $3,000 out of your TFSA in the spring to cover a card payment. Now a bonus or a tax refund has landed, and you want to put it back.
Makes sense. It's your money. It was in there a few months ago.
Here's the catch: the CRA doesn't see it as "putting it back." It sees a brand-new contribution. And if you don't have room for it, there's a penalty.
The rule in one line
Withdrawals are tax-free, and the amount you take out is added back to your contribution room, but not until January 1 of the following year.
So money you withdraw in 2026 only becomes room again on January 1, 2027. Money withdrawn in 2026 only comes back in 2027. It doesn't matter if you took it out in February or December.
Your room at any moment, per the CRA's formula, is the current year's TFSA dollar limit, plus unused room from previous years, plus withdrawals made in the previous year, minus contributions already made. Notice what's missing: this year's withdrawals.
What the penalty actually costs
If you withdraw money and re-contribute it in the same calendar year, pushing your total contributions over your limit, you will be subject to a 1% monthly penalty on the excess amount.
That sounds small. Two things make it add up.
It's charged on the highest excess in the month, not by the day. Over-contribute $2,000 on June 3 and remove it on June 28, and you owe $20 for June. Remove it on July 2 instead, and you owe $20 for June and $20 for July. One day into a new month costs a full month.
It keeps running until you fix it. The penalty runs from the month the over-contribution occurs until the excess is withdrawn or your contribution room increases in following years.
A worked example
Say you've been maxing your TFSA for years and have no unused room. The 2026 limit is $7,000, and your room on January 1, 2026 is $109,000 if you've been eligible since 2009 and never contributed. In this example, you've used all of yours.
- March: You withdraw $3,000 to cover a credit card statement and a car repair.
- November 5: A $3,000 work bonus lands. You deposit it into the TFSA.
- You have no room, so the $3,000 is an excess.
The penalty is 1% × $3,000 = $30 a month.
- November: $30
- December: $30
- Total: $60
On January 1, your March withdrawal is added back as room, and the excess is absorbed. The math is the same one Wealthsimple uses in its own example: a $500 over-contribution left in from November through December would attract $10 in penalty (500 × 1% × 2 months).
Now picture a larger one. Someone puts back $10,000 in September. That's $100 a month. One published example with an $8,000 excess adds up to $320 over four months. Not a disaster. But it's a cost you picked up for no reason, and it's easy to miss.
When re-contributing is fine
The rule isn't "never re-deposit in the same year." It's "only if you have room."
If you've withdrawn some of your TFSA contribution and would like to replace it in the same year, you can only do so if you have contribution room left.
So if you never maxed out, and you have unused room carried forward, the deposit just uses that room. Unused contribution room carries forward indefinitely. The risk is specifically when total contributions for the year, including re-contributions, exceed the year's opening contribution room.
The tricky part is knowing your real number.
Why your room figure might be wrong
Your CRA My Account number can lag. Your previous year's contribution or withdrawal might not be reflected until after the end of February. And if you have more than one TFSA, contributions to every account count toward your limit.
That's why it's worth checking against your own records before you deposit. Count last year's withdrawals, this year's contributions, and every account you hold.
The December wrinkle
This is where the TFSA stops being a simple buffer and becomes a timing question.
A withdrawal on December 28 restores your room on January 1, a few days later. A withdrawal on January 2 restores it on January 1 of the year after, a full year later. Same money. Same account. Twelve months apart.
If you're juggling a couple of cards and a line of credit, and the TFSA is your emergency pad, that matters. Pulling cash in late December and re-depositing in early January keeps the room cycle short. Pulling it in the first week of January means that room stays gone for nearly the whole year.
Nobody can tell you which is right for your situation. But the gap between those two dates is real, and it's easy to stumble into.
If you already put it back too early
It happens. The fixes are plain:
- Withdraw the excess as soon as possible to stop the 1% monthly penalty from accumulating.
- File Form RC243 (the TFSA Return) by June 30 of the following year.
- The CRA usually sends a notice in late spring, after banks report the prior year's transactions in February.
You don't need to wait for the letter.
Treating the TFSA as a cashflow buffer
Lots of people use their TFSA as the place money waits before a bill. It's legitimate. It's tax-free, it's accessible, and it's yours.
But it's a buffer with a rule attached: what goes out doesn't come back until next year. So it helps to know, before you pull from it, whether you can afford for that room to be gone for a while. And to know what's coming in the weeks ahead so you're not pulling reactively.
That's the part cashflow tools are for. In Viktoria, you add your upcoming bills, card due dates, LOC payments and paycheques, and see the gaps before they show up. If a thin week in December is the reason you're eyeing the TFSA, you can see it coming and choose the timing, rather than reacting. Viktoria can also help you map it out if you want to talk it through. It's early access right now at viktoria.app.
