The name does not help. "Savings account" makes people think of a bank account paying a small amount of interest, and many Canadians have used their TFSA exactly that way for years. In reality it is an investment account that happens to be tax-free, and treating it as one can be worth a great deal over a lifetime.
The core idea: you contribute after-tax money, there is no deduction, and everything the account earns, whether interest, dividends or capital gains, is never taxed. Withdrawals are tax-free too.
Who Can Open One and How Much Room You Have
Any Canadian resident with a Social Insurance Number who is 18 or older (19 in some provinces) can open a TFSA. Room starts building the year you turn 18, whether or not you have an account yet. The annual limit is set by the government and indexed in $500 steps. It is $7,000 for 2026.
Because unused room carries forward forever, someone who has been eligible since the TFSA began in 2009 and has never contributed has $116,000 of room in 2026. Anyone born in 1991 or earlier is in that position, and many people have far more room than they realize.
| Item | How it works |
|---|---|
| 2026 annual limit | $7,000 |
| Total room if eligible since 2009 | $116,000 |
| Unused room | Carries forward indefinitely |
| Withdrawals | Added back to your room on January 1 of the following year |
| Tax on growth and withdrawals | None |
Your exact room is in your CRA My Account. Do not rely on your bank’s figure, because it only knows about the accounts it holds.
The Mistake That Costs Real Money
Over-contributing is the most common and most avoidable TFSA error. The penalty is 1% per month of the excess amount, for every month it stays in the account. People usually trigger it in one of two ways.
- Withdrawing and re-contributing in the same year. The room from a withdrawal does not come back until January 1. Take out $10,000 in March and put it back in June, and you have probably over-contributed.
- Moving money between institutions the wrong way. If you withdraw from one TFSA and deposit in another, that is a withdrawal and a new contribution. Use a direct transfer instead, so the room is never touched.
What You Can Hold Inside It
A TFSA can hold the same qualified investments as an RRSP: cash, GICs, bonds, mutual funds, ETFs and individual stocks. The best use depends on your goals and how soon you need the money.
- Money for a purchase or emergency in the next few years belongs in cash or a short-term GIC, where a market drop cannot hurt it.
- Money you will not need for ten years or more is where the tax-free growth does the most work, so a diversified portfolio usually belongs here.
Growth is the point. $7,000 a year invested for 25 years at 6% grows to roughly $385,000, and all of it can be withdrawn tax-free. The same amount in a savings account earning 2% grows to about $225,000. The difference is not the account, it is what is inside it.
Two Things to Watch
US dividends. The tax treaty exempts US dividend withholding inside an RRSP, but not inside a TFSA. If you hold US stocks or US-listed ETFs in a TFSA, 15% is withheld at source and you cannot get it back. For most people this is a reason to hold Canadian and global funds in the TFSA and keep US holdings in the RRSP.
Trading as a business. The CRA can treat frequent, high-volume trading in a TFSA as running a business and tax the profits. Ordinary investing is fine. Day trading is not.
Why It Matters in Retirement
TFSA withdrawals do not count as income. They do not raise your tax bracket, trigger the OAS clawback, or reduce income-tested benefits such as the Guaranteed Income Supplement. That makes the TFSA the most flexible account you have for managing your taxable income in retirement, which is the subject of our article on drawing down your RRSP and TFSA.
Passing It On
You can name your spouse as a successor holder, which lets the account continue in their name with no tax and no effect on their own room. A named beneficiary receives the value tax-free as at the date of death, but the account does not continue, and growth after that date can be taxable to them. For couples, the successor holder designation is usually the better choice, and it is worth checking that it is actually on file.
Where to Start
If you have a TFSA, check your actual room and what the account is invested in. If it is sitting in cash and you will not need the money for years, that is the first thing to look at. If you do not have one, opening it is simple, and the room you are not using is not coming back.
