Key takeaways
  • Paying taxes and debts is part of an estate trustee's duties.
  • A tax sale can be cancelled by anyone who pays the cancellation price within one year after the tax arrears certificate is registered.
  • If the arrears stay unpaid after one year and there is no extension agreement, the land must be offered for sale by public auction or tender.
  • If the home must be sold, a certificate should be obtained before anyone signs an Agreement of Purchase and Sale.

You are the estate trustee and, while sorting through the mail, you find notices showing the property taxes on the deceased person's home were not paid. Perhaps your parent was ill for a long time, or the bills went to an old address. Now you want to know how serious it is and how quickly you need to act.

This article explains how the municipal tax sale process works, why the one-year window matters, and practical steps to catch up. Interest rates and local procedures differ between municipalities, so you will need to confirm the figures with the municipal tax office and a lawyer.

Why the trustee has to deal with it

An estate trustee winds up the deceased's affairs, pays taxes and debts, collects the assets and distributes the residue to those entitled. Property tax on the home is one of those debts. Beneficiaries only receive what is left after debts are paid, so unpaid taxes reduce the estate.

Delay can make things worse. Ask the tax office for the current figure rather than estimating it. Ask for a written statement showing the amount owing, the years it covers and any fees added.

How a municipal tax sale works

When taxes remain unpaid, the municipality's treasurer may register a tax arrears certificate against the property. That registration starts a one-year period. During it, anyone can cancel the sale by paying the cancellation price. The payer does not have to be the owner.

If the amount is still unpaid after one year and there is no extension agreement, the land must be offered for sale by public auction or tender. A municipality and the owner can make an extension agreement that stops the sale at the end of the one-year period. Once a tax deed or notice of vesting is registered, the land is vested free of most estates and interests, except easements and restrictive covenants that run with the land.

StageWhat happens
Taxes unpaidThe municipality may register a tax arrears certificate.
Within one year after registrationAnyone can stop the sale by paying the cancellation price.
Extension agreementThe municipality and owner can agree to stop the sale at the end of the one-year period.
Unpaid after one year, no extensionThe land must be offered by public auction or tender.
Tax deed or notice of vesting registeredThe land vests free of most estates and interests, other than easements and restrictive covenants.

The rules in this area are set by municipal legislation and have been updated over time, so confirm the current wording and the exact cancellation price with the municipality and a lawyer.

Steps to catch up on the arrears

Who can sign documents or access estate funds may depend on whether a certificate of appointment has been issued. That is a practical point to confirm with a lawyer if the clock is running.

If the home will be sold

Selling is a common way to pay the taxes. Probate is normally required if the deceased owned real property that does not pass to another person by right of survivorship, and if real property must be sold, a certificate should be obtained before anyone signs an Agreement of Purchase and Sale. Getting the certificate can take time, so start early if a tax sale deadline is approaching.

Estates valued at up to $150,000 can use a Small Estate Certificate, and larger estates use a Certificate of Appointment of Estate Trustee. For certificates applied for on or after January 1, 2020, Estate Administration Tax is $0 per $1,000 on the first $50,000 and $15 per $1,000 on the rest, and the estate pays it. Ontario real estate counts at appraised date-of-death value, minus encumbrances such as mortgages or liens.

How unpaid taxes are handled at closing depends on your situation, so it is worth confirming with a lawyer.

What to do next

Frequently asked questions

Can I lose the house because of unpaid property taxes?

It is possible. If the amount remains unpaid after the one-year period following registration of a tax arrears certificate and there is no extension agreement, the land must be offered for sale by public auction or tender. Paying the cancellation price within that year can stop it.

Who can pay the arrears to cancel a sale?

Anyone can cancel the sale by paying the cancellation price within one year after registration. That includes the estate trustee or a family member, though you should keep records if a relative is to be repaid.

Can the municipality agree to wait?

A municipality and the owner can make an extension agreement that stops the sale at the end of the one-year period. Whether one is available depends on the municipality, so ask the tax office.

What interest will be charged?

The rate varies by municipality, so ask the tax office for a written statement of what is owing.
