Graduated Rate Estate: Tax Benefits for the First 36 Months in Ontario

An estate is a separate taxpayer from the person who died. Income the estate earns after death, such as rent, interest, or a gain on selling a house, is taxed somewhere, and the type of estate affects how.

If you are an estate trustee in Ontario, you may hear the term graduated rate estate. This article explains what it is, why it matters, and what changes if the estate lasts beyond three years. It is general information, and an accountant should confirm how it applies to your numbers.

What a graduated rate estate is

Under the Income Tax Act, a graduated rate estate is the estate that arose on and as a consequence of an individual's death, for up to 36 months after the death. It must:

• Be a testamentary trust.
• Show the deceased's SIN on its returns.
• Designate itself as the graduated rate estate in its first T3 return.

Only one estate can make that designation for the same individual. It is not something that simply happens without paperwork, so the first T3 return matters.

How it lowers tax

Since the 2016 tax year, a graduated rate estate is taxed at graduated rates. Other trusts created by will, and estates that are no longer graduated rate estates, generally pay the flat top federal rate. The difference can be significant. For 2026, the federal rate is 14% on taxable income up to $58,523, rising in steps to 33% above $258,482. Ontario rates apply in addition, and the province of residence on December 31 decides which provincial rates apply. Brackets change each year, and combined-rate calculations involve more than the bracket tables, so ask an accountant to run the numbers.

There are other features that can help:

• Choice of year-end: a graduated rate estate can choose a non-calendar year-end, up to one year after the date of death.
• Income paid out: amounts the estate allocates to beneficiaries are deducted from the trust's income and generally included in the beneficiaries' income, reported on T3 slips. Income the estate keeps is taxed in the estate.
• Losses: the legal representative can elect under ITA s. 164(6) to treat certain capital losses and terminal losses of a graduated rate estate as losses of the deceased for the final tax year. CRA describes the current window as the estate's first tax year, and a proposed change would extend it to the first three tax years for deaths on or after August 12, 2024. That extension is proposed, so do not rely on it without confirming its status.

What happens after 36 months

The status ends no later than 36 months after the death. The estate has a deemed year-end when it stops being a graduated rate estate. After that, it generally pays the flat top federal rate on income it keeps.

If you can complete the administration and distribute within the period, the estate's income can be taxed at the lower rates for longer. If a dispute, a hard-to-sell property or a delayed clearance certificate pushes the estate past three years, plan for the higher rate on income the estate keeps. A lawyer can tell you whether distributing some income to beneficiaries is an option on your facts.

Filing the estate's T3 return

A T3 return is generally filed for the estate if it realizes any gain or receives any payments after the death. Under the T3 Trust Guide, a return is required when, among other conditions, the trust has tax payable, has disposed of or is deemed to have disposed of capital property, or allocates income to beneficiaries and has total income from all sources of more than $500. A return may not be needed if the estate was distributed right after the death and earned no income before then.

The T3 return and any balance owing are due no later than 90 days after the trust's tax year-end. When a graduated rate estate is wound up, the final T3 return and any balance owing are due no later than 90 days after the date of the final distribution.

What to do next

• Write down the date of death, since the 36-month period and the maximum first year-end both run from it.
• Decide with your accountant what year-end to choose for the estate.
• Make sure the graduated rate estate designation is made on the first T3 return.
• Keep the estate's income and gains separate from the final return so each is reported in the right place.
• Diarize the 90-day T3 deadline after each year-end.
• If the estate may last past three years, get advice early about the tax cost of the change.
