Imagine arriving in Canada in 2022, opening a Tax-Free Savings Account (TFSA) the following year and working hard to set money aside. Then a friend mentions that the cumulative TFSA contribution limit is now more than $100,000.
This sounds like great news, so you contribute $50,000, confident you have plenty of room. But months later, you receive a letter from the Canada Revenue Agency (CRA). It turns out your available contribution room was much lower, and it has assessed a 1% monthly penalty, which has been accumulating on the excess contribution.

It’s one of the most common TFSA mistakes newcomers make, and it’s an understandable one, because the rules can be confusing. But the penalties can add up quickly if you make a mistake and don’t catch it early.

How does TFSA contribution room work for newcomers?
The TFSA was introduced in 2009, and unused contribution room carries forward indefinitely for anyone who was a Canadian resident and at least 18 years old during those years.
This means that in 2026, any Canadian who has been a resident every year since 2009 and never contributed has $109,000 of cumulative room available, based on the federal government’s 2026 annual dollar limit of $7,000. However, newcomers don’t receive credit for the years they weren’t Canadian residents.
According to the CRA, you only start accumulating TFSA contribution room in the year you become a resident of Canada for tax purposes. Any years that you spend living outside of Canada before that don’t count, regardless of your age.
For example, a newcomer who became a resident in 2022 would have accumulated only the annual limits available since then: $6,000 (2022), $6,500 (2023), $7,000 (2024), $7,000 (2025), and $7,000 (2026). It works out to $33,500 in available room.'

A common TFSA mistake new arrivals make
Some newcomers make the mistake of contributing to their TFSA as if they had the full cumulative room available to long-term residents.
Recalling our hypothetical case, if a newcomer who arrived in 2022 contributed $50,000 to a TFSA in 2026, they would exceed the limit. With the actual room at $33,500, they would have an excess of roughly $16,500. The CRA charges a penalty of 1% per month on the highest excess amount in the account for each month it remains. In this case, it works out to about $165 a month, or almost $2,000 a year, until the overcontribution amount is withdrawn.

Compounding the problem, the CRA doesn’t always send a notice immediately, so your bill can grow significantly before you realize anything is wrong.

How do I check my actual TFSA room on CRA My Account?
The most reliable way to confirm your real TFSA contribution room is to log in to CRA My Account, the federal government’s online portal for individual tax information. Your TFSA contribution room and most recent contribution history appear under the RRSP and TFSA tab.
But before you rely on that figure, here are a few important things to keep in mind:
- CRA My Account updates after financial institutions report contributions. This typically happens annually, which means the number you see may not reflect the most recent deposits.
- If you’ve already made TFSA contributions earlier in the current calendar year, subtract those amounts from the displayed figure to estimate your remaining room.
- Your bank or investment platform can only track the total contributions you made through that institution. It cannot calculate your totals across different banks.
If something looks off, you can contact the CRA by telephone at 1-800-959-8281 for help with your TFSA and any other registered accounts.
What should I do if I’ve already over-contributed?
If you’ve contributed too much to your TFSA, there are two steps you should take right away.

First, withdraw the excess amount as soon as possible. The 1% monthly tax is based on the highest excess amount during each month, so removing the excess prevents the penalty from continuing to grow.
After you’ve withdrawn that amount, you must submit a TFSA return (Form RC243). This has to be done by June 30th in the year after the tax takes effect, or you could incur additional penalty charges.
If your failure to meet your tax obligations was due to circumstances beyond your control, you may also be able to request relief from the CRA. Simply being a newcomer isn’t enough on its own, but an honest mistake that you quickly fix might be viewed more favourably than one that remains unresolved.
Why is this mistake so easy to make — and what should you do now?
Unfortunately, much of the public information about TFSAs focuses on the cumulative contribution limit since 2009. Also, banks and investment platforms generally don’t block contributions that exceed your available room because they don’t know what you’ve contributed elsewhere.
Thankfully, overcontributions are usually easy to fix if you’ve caught them early. Depending on the amount, an over-contribution that is corrected within the first month or two may cost less than $100. However, left unchecked, the penalties can quickly grow into hundreds or even thousands of dollars.
Before you make your next TFSA contribution, take the following precautions:
- Log in to CRA My Account and confirm your available TFSA contribution room.
- Remember that TFSA room starts accumulating in the year you became a Canadian resident for tax purposes, not in 2009.
- If you’ve over-contributed, withdraw the excess amount as soon as possible to stop additional penalties from accruing.
- File Form RC243 by June 30 of the following year if you’re required to report an over-contribution.
- If the mistake was an honest error that you corrected quickly, consider asking the CRA to waive the tax under its taxpayer-relief provisions.
- If you have TFSAs at multiple institutions, remember that it’s your responsibility to know how much you’ve contributed in total.
Ultimately, the same rule that confuses many newcomers is also the one that protects them from future penalties. Start counting TFSA room from the year you arrived in Canada, verify your numbers with the CRA and disregard the six-figure “since inception” limits when you see them mentioned.
