TFSA power — and red flags
Commentary this week recharged the case for maxing TFSA room as the top tax‑free engine for windfalls, but the CRA is watching overcontributions and signs of running a 'business' inside a TFSA — penalties apply immediately, so track room and correct mistakes fast ( ).
The TFSA dollar limit for 2026 is $7,000, and Canadians who have been eligible since 2009 but never contributed now have $109,000 in cumulative contribution room. (canada.ca) The CRA charges a 1% tax for each month that any excess amount remains in a TFSA, calculated on the highest excess balance for that month, and that tax applies even if the excess is withdrawn within the same month. (canada.ca) Practical example used by advisers: contributing $7,000 in January, withdrawing $4,000 in March, then re-contributing that $4,000 in June results in $11,000 of contributions in 2026 and a 1% monthly penalty on the $4,000 surplus unless unused room from prior years exists. (ca.finance.yahoo.com) If the excess contribution occurs while the account holder is a non-resident, the CRA can impose two separate 1% monthly taxes — one for the excess amount and one for the non-resident contribution rule — effectively doubling the monthly penalty. (canada.ca) The Tax Court’s 2023 ruling in Canadian Western Trust Co. (as Trustee of the Fareed Ahamed TFSA) v. The King, 2023 TCC 17, found the TFSA was “carrying on a business,” which stripped the tax-free treatment from the account’s trading income. (taxlawcanada.com) CRA guidance and recent commentary flag specific activities that trigger the business test: frequent short-term trades, foreign-currency and derivative trading, and systematic option-writing or day-trading inside a TFSA have been identified as red flags. (fool.ca) To correct an excess, taxpayers must file a TFSA return (and any required payment) by June 30 of the calendar year after the year the tax applies—for example, excesses in 2024 must be reported by June 30, 2025.
