Key takeaways
  • Assets held jointly that automatically pass to the surviving owner are not counted in the estate value for Estate Administration Tax.
  • When a parent adds an adult child to an account without payment, the law presumes the child holds the money in trust for the parent's estate unless evidence shows the parent intended survivorship.
  • Gifts to minor children start from the opposite presumption, that the transfer was a gift.

You have lost someone, and your name was on their bank account. You may be wondering whether that money is yours now, or whether it has to be listed as part of the estate and tied up in probate.

The answer often depends on why the account was joint in the first place. This article explains the general rule, the presumption that can pull a joint account back into an estate, and what to gather if the question comes up.

The general idea: survivorship versus the estate

Many joint accounts are set up so that, when one owner dies, the other owner automatically takes the money. This is called a right of survivorship. Assets held jointly that automatically become the property of the other owner or owners on death are not included in the estate value used to calculate Estate Administration Tax.

By contrast, the tax is based on the value of all assets the deceased owned at the time of death, including bank accounts held in their own name, investments and property held in another person's name. So the question is whether the money in a joint account really belonged to the survivor by survivorship, or whether it is treated as still belonging to the person who died.

The presumption that can bring the money back in

When a parent puts money into a joint account with an adult child without receiving payment (a gratuitous transfer), the law presumes the child holds that money in trust for the parent's estate. This is called a resulting trust.

The presumption is not final. It can be rebutted by evidence, on a balance of probabilities, that the parent intended the child to have the right of survivorship. In plain words, the survivor has to show it is more likely than not that the parent meant the child to keep what was left.

There is an exception for minor children. For gratuitous transfers from a parent to a minor child, the starting point is instead a presumption of advancement, meaning the transfer is presumed to be a gift.

These rules come from court decisions rather than a single statute. Accounts between spouses, or accounts that are not between a parent and a child, can raise different considerations, so a lawyer can confirm how they apply to your facts.

Why it matters for probate and tax

If the presumption is not rebutted, the money may be treated as belonging to the estate rather than to the survivor. That can affect who is entitled to it and how it is reported when the estate trustee applies for a certificate.

Where an estate certificate is needed, the Estate Administration Tax is paid as a deposit when the application is filed with the Superior Court of Justice, and the estate pays it, not the estate trustee personally. There is no tax on the first $50,000 of the estate's value, and above that the tax is $15 for every $1,000 or part of $1,000. A $500,000 estate, for example, would pay $6,750.

The estate trustee also has reporting duties. An Estate Information Return must be filed with the Ministry of Finance within 180 calendar days after the certificate is issued, listing each asset and its value on the date of death. If new assets are found or the return was wrong, an amended return is due within 60 days of becoming aware. A joint account that later turns out to belong to the estate is the kind of discovery that can trigger that duty.

Evidence that can matter

Because the presumption can be rebutted by evidence, documents and accounts of what was said can become important. The following kinds of material are commonly relevant:

No single item decides the matter. A court looks at the overall picture of what the person intended when the account was opened or the money was added.

What to do next

If beneficiaries or other family members disagree about the account, it is worth getting advice early. A lawyer can explain how the presumption may apply to your situation.

Frequently asked questions

Does a joint bank account go through probate in Ontario?

Assets held jointly that automatically pass to the other owner on death are not included in the estate value for Estate Administration Tax. However, a joint account with an adult child can be challenged under the resulting trust presumption, so it depends on the facts.

What is a resulting trust on a joint account?

It is a legal presumption that when a parent adds an adult child to an account without payment, the child holds the money for the parent's estate. The child can rebut it with evidence that the parent intended survivorship.

Is it different if the child was a minor?

Yes. For gratuitous transfers from a parent to a minor child, the starting point is a presumption of advancement, meaning the transfer is presumed to be a gift.

Does the estate trustee have to report a joint account?

The Estate Information Return lists each asset and its value on the date of death. Whether a particular joint account belongs on it depends on whether it passes by survivorship, so a lawyer or accountant can confirm in your case.
