Key takeaways
  • Jointly owned property that passes automatically to the other owner is not included in the estate value for estate administration tax.
  • A joint asset the survivor holds on resulting trust for the estate does not escape the tax.
  • Joint ownership can still be affected by support claims, the matrimonial home rules and income tax.

Many families add a child or partner to a house or bank account hoping to keep it out of probate. Sometimes that works, but it can also create problems.

This article explains when joint assets skip probate and estate administration tax in Ontario, and where the limits are. A lawyer can look at your documents and the family facts.

The general rule

Property passes to the estate trustee only if no one else has a right to take it by survivorship, and survivorship overrides the will. Ontario lists jointly owned property that passes automatically to the other owner as not counted in estate value for estate administration tax.

A house held in true joint tenancy by a surviving owner can be dealt with without a Certificate of Appointment of Estate Trustee.

Where joint ownership does not avoid the estate

Courts may look at the wording of bank documents, control and use of the funds, a power of attorney, and tax treatment to decide what the transferor intended. Financial dependency of an adult child does not create a presumption of gift, though it can be strong evidence against a resulting trust.

Estate administration tax and what is included

For applications on or after January 1, 2020, there is no tax on an estate worth $50,000 or less, though the return is still required. Above $50,000, the tax is $15 for every $1,000 (or part) of the estate's value, due when the estate certificate is issued.

What to do next

Frequently asked questions

Does a joint bank account avoid probate?

Often, but not always. Many joint accounts include survivorship, and the survivor becomes the owner. Heirs may challenge the survivor, who may need to show the deceased intended a gift.

Is estate administration tax payable on a jointly owned house?

Jointly owned property that passes automatically to the other owner is not included in estate value. If the survivor holds the asset on resulting trust for the estate, it is included.

Is it a good idea to add my child to my house?

It depends. It can bring tax consequences, because a gift of capital property is treated as a sale at fair market value. An adult child added without paying is presumed to hold the asset in trust for you, and for your estate on your death, while a gift is presumed only for a minor child. If the home is a matrimonial home that you hold jointly with a child and not with your spouse, the joint tenancy is deemed severed immediately before your death, so your share goes into your estate. Get advice first.

Can a dependant still claim against joint property?

Yes, in some cases. For a support claim, certain joint property and deposits can be deemed part of the net estate. A support application generally must be made within six months of the certificate of appointment, with some exceptions for undistributed property.
