5 TFSA mistakes that cost you thousands

TL;DR: A TFSA is not a piggy bank earning a tiny rate — it's a place for investments that grow tax-free. The five mistakes below quietly cost newcomers thousands of dollars. Almost everyone makes the fourth one.

Came from the video and commented "TFSA"? Here are all five mistakes in detail. 👇

Mistake 1 — treating a TFSA like a savings account

The most common one. A TFSA at 1–2% is a wasted tool. The power of a TFSA is that growth is never taxed — so it's logical to hold things that actually grow, not just "sit." Details in the full TFSA guide.

Mistake 2 — over-contributing past the limit

The 2026 limit is $7,000 plus your unused room. Go over, and the CRA charges a 1%-per-month penalty on the excess for as long as it's there.

⚠️ Critical for newcomers: room counts from the year you became a tax resident, not from 2009. Don't trust apps showing $102K. Verify the exact figure in CRA My Account.

Mistake 3 — contributing and withdrawing in the same year

A common myth: "I withdrew, so my room came back instantly." No. The amount you withdraw returns to your room only the next calendar year. Withdraw and re-contribute the same amount in the same year, and that's an over-contribution (see mistake 2).

Mistake 4 — holding US dividend stocks in a TFSA

The one almost everyone makes. US-stock dividends are subject to a withholding tax that a TFSA does not shield — unlike an RRSP, where the tax treaty applies. Asset location matters.

Mistake 5 — not opening the account at all

Waiting for "a better moment." Room accumulates, but time in the market does not. The best moment was yesterday; the second best is today.
