- The legal representative can set a graduated rate estate's first tax year-end at any date up to one year after the death.
- The T3 return is generally due 90 days after the trust's year-end, so the date you pick drives your deadline.
- Graduated rate estate status lasts for up to 36 months after death, and the estate has a deemed year-end when that status ends.
- Testamentary trusts that are not graduated rate estates do not get this choice and have a December 31 year-end.
When someone dies, their executor (the estate trustee) often assumes the estate has a calendar year-end, like most individual taxpayers. For many estates that is not the rule. An estate that qualifies as a graduated rate estate can choose when its first tax year ends, and that choice affects when the T3 return is due.
This article explains what a graduated rate estate is, how the year-end choice works, and what to think about before you pick a date. It is general information, not tax advice. The right date depends on the estate's income, assets and plans, so it is worth confirming with an accountant or lawyer.
What a graduated rate estate is and why it gets a choice
A graduated rate estate, often shortened to GRE, is a special tax status for the estate of a deceased person. The estate is treated as a trust for tax purposes, and the executor files T3 trust returns for it. GRE status matters because its income is taxed at the same graduated rates as individuals.
There are conditions. An estate can only be a GRE for up to 36 months following the death, it must be a testamentary trust, and it must include the deceased's SIN on its T3 returns and designate itself as the GRE in its T3. Only one estate per individual can be the GRE.
The year-end choice comes with that status. The legal representative can set the GRE's first tax year-end at any date up to one year after death. Testamentary trusts that are not GREs have a December 31 year-end.
How the year-end drives your T3 deadline
A GRE's T3 return is due 90 days after the trust's tax year-end, or 90 days after the final distribution if the estate winds up that way. So the year-end you choose sets the filing date. A year-end soon after death means an earlier first return. A year-end further out gives more time before the first return is due, up to the one-year limit.
The deadline for the return and the deadline for any balance owing are tied together. When the estate stops being a GRE, there is a deemed year-end on that day, which can be no later than 36 months after death. The T3 and balance owing are due within 90 days of that year-end. If the estate ends by final distribution, the year ends on that date and the return is due 90 days later. Late-filing penalties can apply.
| Situation | Year-end | T3 due |
|---|---|---|
| GRE, first year | Any date you set, up to one year after death | 90 days after that year-end |
| GRE status ends (no later than 36 months after death) | Deemed year-end on the day it ceases to be a GRE | Within 90 days of that year-end |
| Estate wound up by final distribution | The date of final distribution | 90 days later |
| Testamentary trust that is not a GRE | December 31 | Based on that year-end |
Why the date matters for planning
Choosing a year-end is not only about paperwork. Because a GRE is taxed at graduated rates like an individual, how income is spread across tax years can matter. Which year-end suits the estate depends on what income it expects and when, so this is a good question to put to an accountant.
- Income timing: the estate's income after death is reported on the T3, while the deceased's income up to the date of death goes on the final personal return. For example, rental income from January 1 to the date of death goes on the final return, and rental income the estate earns after death goes on line 8 of a T3.
- Donations: GRE donations can be claimed in the year made or any of the following 5 years, or carried back, so the year-end can matter if the will includes charitable gifts.
- Sale of assets: capital property is treated as disposed of just before death at fair market value on the final return, and a later sale is taxed on the sale price less that value.
- Winding up: the 36-month limit on GRE status is a fixed outer boundary, so the estate's plan for distributing assets should be considered when choosing a date.
There is rarely one obviously correct answer. Beyond the points above, how the choice affects tax payable depends on the facts, and a tax professional can model it.

The estate's T3 year-end is separate from the deceased's final personal return. The final T1 is due April 30 of the following year for deaths from January 1 to October 31, or six months after death for deaths from November 1 to December 31. For a self-employed person the filing date is June 15, or six months after death for deaths from December 16 to 31, but payment is still due on the original date.
A Rights or Things return, where it applies, is due the later of one year after death or 90 days after the final return's assessment.
Before the estate can file a T3 electronically for the first time, the trustee needs a trust account number. You can apply online or with Form T3APP, which is not sent with the T3 return. The number must appear on every T3 return, and a $100 penalty is noted for failing to provide it.
What to do next
Treat the year-end as a decision to make early, not a detail to discover when the first return is due. These steps can help you work through it.
- Confirm the date of death and the date you were appointed, and note the one-year limit for setting the first year-end.
- List the estate's expected income, such as rent, interest, dividends or sale proceeds, and when each will arrive.
- Check whether the will includes charitable gifts, because donation timing may matter.
- Apply for the trust account number early using Form T3APP or online.
- Diarize the 36-month limit on GRE status and the 90-day T3 deadline that follows each year-end.
- Ask an accountant to compare year-end options before you commit, and keep a written record of the date you choose.
If the estate is large, has complicated assets, or beneficiaries disagree about timing or distributions, a lawyer can explain your duties as estate trustee, and an accountant can handle the tax side.
Frequently asked questions
Can every estate choose its own year-end?
No. The choice is described for graduated rate estates, where the legal representative can set the first tax year-end at any date up to one year after death. Testamentary trusts that are not GREs have a December 31 year-end.
When is the T3 return due for a graduated rate estate?
It is due 90 days after the trust's tax year-end, or after the final distribution. Late-filing penalties can apply.
How long can an estate stay a graduated rate estate?
For up to 36 months following the death. The estate has a deemed tax year-end on the day it ceases to be a GRE, and the T3 and any balance owing are due within 90 days of that year-end.
Do I need a trust account number before filing the T3?
Yes. Trustees apply online or with Form T3APP, and a trust filing for the first time needs the account number before filing electronically. The number must be on every T3 return, and a $100 penalty is noted for failing to provide it.
