TFSA: The Complete Canadian Guide

The Tax-Free Savings Account (TFSA) is one of the most powerful savings tools available to Canadian residents aged 18 or older. Contributions are made with after-tax dollars, but all investment growth — interest, dividends, and capital gains — is completely tax-free. Withdrawals are also tax-free and, crucially, do not affect your eligibility for income-tested government benefits like OAS, GIS, or the Canada Child Benefit.

The TFSA contribution limit for 2026 is $7,000. If you were 18 or older in 2009 (when the TFSA was introduced) and have never contributed, your cumulative room is $109,000. Unused contribution room carries forward indefinitely, and any amount you withdraw in a year gets added back to your room in the following January. This re-contribution feature makes TFSAs uniquely flexible for both short-term and long-term savings.

Common TFSA mistakes include over-contributing (which triggers a 1% per month penalty on the excess), withdrawing and re-contributing in the same calendar year (which counts as a new contribution against your room), and holding foreign dividend-paying stocks directly (U.S. dividends in a TFSA are subject to 15% withholding tax because TFSAs are not recognized under the Canada-U.S. tax treaty, unlike RRSPs). For maximum growth, consider holding your highest-growth investments — such as Canadian equity ETFs or Canadian dividend stocks — inside your TFSA.
