Successor holder or beneficiary? One line on a TFSA form

There is a box on the TFSA application that most people fill in without being told what it does. It takes ten seconds and it is worth a great deal.

The three outcomes

Successor holder — available only to a spouse or common-law partner. On your death, they simply become the account holder. The TFSA continues intact. It keeps its tax-free status, it keeps growing tax-free, and it does not use any of their own contribution room.

Beneficiary — available to anyone. The account is paid out. The value at the date of death is tax-free; any growth after that date is taxable to the recipient. If the recipient wants to keep the money sheltered, they must have their own TFSA room to put it in.

Nothing named — it falls into your estate. Probate, delay, legal fees, and exposure to creditors.

What the difference is worth

A $95,000 TFSA, and a spouse who has already used all their own room.

• Successor holder: they inherit a $95,000 tax-free account that keeps compounding tax-free forever. Nothing is lost.
• Beneficiary: they receive $95,000. It is tax-free on arrival, but they have no room to shelter it, so from that day forward every dollar of growth is taxable in a regular account.

Over twenty years, on the same investments, that gap is not small. And the only difference between the two outcomes is which box was ticked on a form.

If you are married or in a common-law relationship, successor holder is almost always the right answer.

Quebec is different

Quebec does not recognise beneficiary designations on a TFSA made through the plan document. There, the designation is made in a will. If you have any connection to Quebec, take advice specific to it.

While we are on designations

Three more that are worth ten minutes each:

• Contingent beneficiary. Who inherits if your first beneficiary dies before you. Without one, you are back to the estate.
• Naming a minor directly. In Alberta, insurance money payable to a minor generally cannot be paid to them directly and may require a trustee or court involvement. Naming a trustee for a minor beneficiary avoids a genuinely painful process at a genuinely bad time.
• Designations after a separation or divorce. These do not update themselves. A designation made in 2014 naming a former spouse stays in force until you change it, regardless of what has happened since. This is one of the more common and more upsetting mistakes in the whole field.

How to check yours

Log into each account — TFSA, RRSP, RRIF, workplace pension, group life — and look at the beneficiary section. Not the one you remember filling in. The one that is there now.

It takes about twenty minutes for a whole household and it is the highest-value twenty minutes of admin available to most people.

Where I come in, and where I do not

Through my insurance licence I can place segregated funds and annuities inside a TFSA, which carry beneficiary designation that bypasses the estate along with maturity and death benefit guarantees — at higher fees than an equivalent mutual fund. Whether that trade is worth making depends on your situation, and for a salaried employee with no creditor exposure it frequently is not.

I cannot give you legal or tax advice on your estate. For anything involving a blended family, a trust, a business, or a beneficiary with a disability, you need a lawyer as well — and I will tell you that rather than guess.
