Key takeaways

This lesson applies to Canada. The Tax-Free Savings Account, or TFSA, is a Canadian account, and the rules described here are the Canada Revenue Agency's. They depend on your circumstances, such as residency, and they change, so the CRA pages linked below are the final word. A TFSA is the Canadian version of the tax-free design from tax-advantaged accounts explained. Contributions are not tax deductible. In exchange, any interest, dividends or capital gains you earn inside are generally tax-free, even when you take the money out. The CRA also says you can withdraw at any time, for any reason, without affecting your eligibility for federal benefits and credits. The name is a little misleading. A TFSA is not only a savings account. It is a type of account that can hold cash, and it can also hold investments.

It all comes down to room

Your contribution room is how much you are allowed to have put in. It grows every January 1, carries forward if you do not use it, comes back after a withdrawal, and is never increased by investment gains. Almost every TFSA problem is a room problem.

How room builds. If you are a resident of Canada, your contribution room starts to build when you turn 18. Each January 1 the CRA adds that year's TFSA dollar limit. The room accumulates whether or not you open an account or file a tax return, and anything you do not use carries forward to later years. New residents start building room from the year they become resident, if they are 18 or older. Periods as a non-resident work differently, and the CRA has a separate page on them. Your room for a year is made up of four parts: that year's dollar limit, any unused room from earlier years, the amount you withdrew in the previous year, minus anything you have already contributed this year. The current dollar limit, and the total of every yearly limit since the TFSA began in 2009, are in the table below. Your own figure is in your CRA account, and it is worth checking against your own records because the CRA only receives updates from financial institutions periodically. Gains do not create room, and losses do not take it away. If you put in $12,000 and it grows to $15,000, you have not used $15,000 of room. If it falls to $9,000, you have not got $3,000 back. Room tracks the money you put in and took out, not what the investments did. Losses inside a TFSA also cannot be claimed as a capital loss on your tax return.

Withdrawals. You can take money out of a TFSA whenever you like, and you will regain the same amount as new contribution room. The catch is the timing: the amount you withdraw is only added back on January 1 of the next calendar year. If you have already used all your room this year, putting a withdrawal straight back in creates an excess amount. Over-contributing. Any excess in your TFSA is taxed every month for as long as it stays in the account, at the monthly rate shown in the table above. There is no small allowance before this starts: it applies from the first dollar of excess. The CRA's own advice is to withdraw an excess as soon as possible rather than waiting to be contacted, and you still have to file a TFSA return for it. Moving money between TFSAs yourself, by withdrawing from one and depositing in another, counts as a new contribution. A direct transfer arranged between financial institutions does not.

Worked example: putting a withdrawal back too soon

Someone has $20,000 of TFSA room at the start of a year. That is an illustrative round number, not a real limit.

Contribute in March (Room left this year: $0)$20,000
Withdraw in July (Room left this year: still $0. The $5,000 comes back next January 1.)$5,000
Put the $5,000 back in September (There was no room left, so all of it is excess)Excess of $5,000
Tax while it stays (1% of $5,000, the CRA monthly rate in the table above)$50 a month
Excess left in from September to December (4 months x $50)$200
Room on January 1 next year (The July withdrawal is added back)Next year's dollar limit + $5,000
Cost of waiting until January 1 to put it back$0

Illustrative numbers. The monthly rate is the CRA's, checked on the date shown in the table.

Adds to room
A new year's TFSA dollar limit on January 1, Room you did not use in earlier years, Last year's withdrawals, on January 1
Does not add to room
A withdrawal earlier this same year, A 30% gain on your investments, Opening a second TFSA at another bank

What a TFSA can hold. The types of investments permitted in a TFSA are generally the same as in an RRSP: cash, mutual funds, securities listed on a designated stock exchange, guaranteed investment certificates, bonds and certain shares of small business corporations. Prohibited and non-qualified investments are taxed, so the rules on what you hold matter as much as the rules on how much. Because growth inside a TFSA is not taxed, what you hold changes how much the account is worth to you. A TFSA holding only cash at a low interest rate shelters a small amount of tax. One holding investments that grow over decades shelters the tax on all of that growth, and also exposes it to the investments' ups and downs. Compounding and time shows why the years matter so much, and ETFs vs individual stocks covers two common things people hold.

Flexibility cuts both ways

Being able to withdraw tax-free at any time makes a TFSA useful for goals of any length. It also makes it easy to spend money that was meant to keep compounding. The account does not decide what the money is for. You do.

The TFSA is often compared with the RRSP, which works the opposite way round. TFSA vs RRSP compared walks through when the two come out the same and when they do not. If you are saving for a first home, FHSA explained covers the account built for that. And if you have not invested before, how to start investing covers the groundwork.

You understand how the TFSA works

You can now explain how TFSA room builds, why a withdrawal waits until January 1 to come back, and what an excess costs.

Check your understanding

You withdraw $4,000 from your TFSA in June. When does that $4,000 become contribution room again?
On January 1 of the next calendar year. The CRA adds withdrawals back to your room at the start of the following year.
Which of these increases your TFSA contribution room?
Each new year's TFSA dollar limit, from the year you turn 18 while resident in Canada. The new dollar limit is added every January 1 and accumulates even if you never open an account.
What does the CRA charge on an excess TFSA amount?
A tax every month for as long as the excess stays in the account. The monthly rate is in the table in this lesson. The longer the excess stays, the more it costs.
Can a TFSA hold investments such as funds and listed shares?
Yes, the investments permitted are generally the same as in an RRSP. The word savings in the name is misleading. Cash, funds, listed securities, GICs and bonds are generally allowed.

Common questions

Are TFSA withdrawals taxable?
Generally no. The CRA says interest, dividends and capital gains earned in a TFSA are generally tax-free, even when you withdraw. Withdrawals also do not affect eligibility for federal benefits and credits.
When can I put back money I withdrew from my TFSA?
The amount you withdraw is added back to your contribution room on January 1 of the next calendar year. Re-contributing earlier only works if you still have other unused room.
What happens if I over-contribute to my TFSA?
Any excess amount is taxed every month it remains in the account. The CRA advises withdrawing an excess as soon as possible. The current monthly rate is listed on the CRA's over-contribution page.
