Introduced by the Canadian federal government in 2009, the Tax-Free Savings Account (TFSA) has become one of the most popular registered accounts in Canada, with millions of account holders.
Its popularity is well-deserved: the TFSA is incredibly flexible. Any capital gains, interest, or dividends earned within the account grow completely tax-free, and withdrawals can be made at any time without triggering a tax bill. However, despite its simple name, many Canadians fall into costly traps. Here are four common TFSA mistakes and how to avoid them.
1. Accidentally Overcontributing
The CRA sets a strict annual limit on how much you can contribute to a TFSA (for example, the limit for 2026 is $7,000, plus any unused space carried forward from previous years). Overcontributions typically occur when people withdraw and re-deposit funds in the same calendar year.
The Rule: When you withdraw money from a TFSA, that withdrawal amount is added back to your contribution room, but only on January 1st of the following calendar year.
- If you maximize your TFSA in January, withdraw $5,000 in June, and then put that $5,000 back in September of the same year, you have overcontributed by $5,000.
- The CRA charges a penalty of 1% per month on the excess amount until it is removed.
2. Using the Account Solely for Cash Savings
The word "Savings" in TFSA is highly misleading. Many Canadians open a TFSA at their retail bank and leave the funds sitting in cash, earning negligible interest.
Because all growth in a TFSA is tax-free, you lose a massive opportunity by not holding growth-oriented assets. Instead of cash, consider utilizing your TFSA room to hold mutual funds, exchange-traded funds (ETFs), individual stocks, or guaranteed investment certificates (GICs) to benefit from tax-free compound growth over the long run.
3. Withdrawing Funds Manually to Switch Institutions
If you find a better interest rate or investment option at another financial institution, you might be tempted to withdraw all funds from your current TFSA bank account, deposit it into your personal chequing account, and then deposit it into a new TFSA account at the new bank.
Doing this counts as a new contribution. If you have already used up your contribution room for the year, this action will trigger an overcontribution penalty.
The Solution: Always ask the new financial institution to initiate a Direct Transfer (also known as an administrative transfer) on your behalf. This moves the assets directly between TFSAs without affecting your contribution room.
4. Believing Unopened Account Contribution Room is Lost
A common myth is that if you did not open a TFSA back in 2009, you have permanently lost the contribution room for those years.
In reality, TFSA contribution room accumulates automatically every year from the year you turned 18 and became a Canadian resident, regardless of whether you have opened an account. If you turned 18 before 2009 and have never contributed, you will have a massive cumulative room available. You can open an account today and utilize that full room instantly.
