The Tax Free Savings Account, and the Rule Almost Everyone Gets Wrong

Here is the unwelcome part, and it should be said before anything else. The single most common mistake with this account is not choosing the wrong investment. It is putting money back in the same year it came out, because a withdrawal does not give the room back until January.

The withdrawal rule, in the agency’s own words

Take this one slowly, because it costs people money every year.

The agency states that a contribution is applied immediately against available contribution room, reducing it by the same amount contributed. That part surprises nobody.

Then it states the other half: withdrawals will only create new available contribution room in the account the next calendar year.

The next calendar year. So money taken out in February does not free any room in March, in June, or in December. It frees room in January of the following year.

A person who withdraws and replaces in the same year has almost certainly over contributed, and the tax on an excess amount runs monthly for as long as the excess remains. That is the arithmetic, not an opinion, and it is why this section is first.

What the account is, and what it is not

The agency’s description is worth reading for what it does not say. It is a registered savings account that functions like an investment account, which can hold cash savings and investments that generate tax free income.

Nothing in that sentence mentions retirement, and nothing mentions a deduction. The agency confirms both directly: contributions are not tax deductible, income earned through interest, dividends or capital gains is generally tax free, and contributions and income are generally tax free even when a withdrawal is made.

So the trade is the reverse of a retirement plan. No relief on the way in, nothing owed on the way out.

To open one, the agency lists three conditions: be eighteen years of age or older, be a resident of Canada for income tax purposes, and have a valid social insurance number. It adds a wrinkle worth knowing in a household with a nineteen year old: some provinces and territories require a person to be nineteen to enter a contract, and the contribution room still accrues from eighteen.

Over contributing, and how it happens to careful people

The agency’s rule is short: any excess amount is taxable monthly for as long as it remains in the account, and if the over contribution is deliberate there may be additional tax consequences.

What makes this worth a section is that it rarely happens through carelessness. It happens through the withdrawal rule above, and it happens through moving an account between institutions, where a withdrawal and a fresh contribution look like a transfer to the person doing it and look like two separate transactions to the agency.

Ask the institution, in writing, whether a move is being processed as a direct transfer between accounts or as a withdrawal followed by a contribution. Those are two different events and only one of them is safe.

And get the number from the agency rather than from an institution. Your own room is tracked by the agency, and an institution only sees the part of your life that passes through its own systems.

Leaving Canada

This one catches people who move for work and keep an account open behind them.

The agency states that only residents of Canada may contribute to their account tax free, and that contributions may be made up to the date a person becomes a non resident.

After that date, a contribution is a taxable non resident contribution, and a tax applies for each month the contribution remains in the account.

Holding the account is a different question from contributing to it. If a move is coming, the question to put in writing before the move is what happens to contributions, to room, and to the account itself.

On a death, and the Quebec difference

The agency publishes two different routes, and the difference between them is large.

A successor holder is the survivor of the deceased who is named as the new holder of the account, in the contract or in the will. The agency states that the successor holder immediately becomes the new holder and assumes ownership on the death of the deceased holder. The account continues.

A designated beneficiary may be a survivor, a family member, or another person or organisation named in the contract or the will. A designated beneficiary does not pay tax on an amount received up to the fair market value of the property held in the account at the date of death. The account does not continue in the same way.

Now the part that matters in Quebec, and it is the agency’s own sentence: Quebec does not recognise the designation of successor holder for these accounts.

That is not a small administrative note. It means a Quebec household cannot rely on the mechanism that households elsewhere in Canada are routinely told to use, and that what happens to the account on a death has to be arranged another way. That is a notary’s question, and it is worth asking before it is needed.
