Settling an estate in Ontario usually means filing four separate tax returns, each with its own purpose, deadline, and recipient: the deceased’s final T1 personal return, an optional “rights or things” return, a T3 trust return for income the estate earns after death, and the provincial Estate Information Return. The estate tax return in Ontario is not a single document but a set of federal and provincial filings, and missing any of them can produce penalties, a delayed clearance certificate, or personal liability for the trustee.
The Final T1 Return
The deceased’s final T1 covers January 1 of the year of death through the date of death. It reports the usual income — employment, pensions, investment income — but it also carries a tax event most people never encounter in life: a deemed disposition of capital property.
Under the Income Tax Act, the deceased is treated as having sold every piece of capital property immediately before death at fair market value, even when nothing was actually sold.1Canada Revenue Agency. Taxable Capital Gains on Property, Investments, and Belongings The gain or loss on each asset is fair market value at death minus the adjusted cost base. This applies to real estate, stocks, mutual funds, and other capital property.2Justice Laws Website. Income Tax Act RSC 1985, c. 1 (5th Supp.) – Section 70 For someone who owned a cottage, a rental property, or a long-held portfolio, the deemed disposition is usually where most of the final tax bill comes from. Formal appraisals are worth the cost, because an inaccurate valuation can trigger reassessment years later.
The main exception is property transferred to a surviving spouse or common-law partner. That transfer can happen at the deceased’s adjusted cost base rather than fair market value, deferring the capital gain until the survivor eventually sells or is themselves deemed to dispose of it. The rollover applies automatically unless the legal representative elects otherwise on the final return.
The final T1 is generally due April 30 of the year following the year of death. If the deceased or their surviving spouse was self-employed, filing extends to June 15, but any balance owing is still due by April 30. If death occurs late in the year (November or December), the return is due six months after the date of death.
The Optional Rights or Things Return
A second, optional return can be filed for income the deceased had earned but not yet received. CRA calls these “rights or things,” and they include unpaid salary or vacation pay for a completed pay period, declared but unpaid dividends, uncashed bond coupons, and CPP or OAS payments for the month of death that arrived after death.3Canada Revenue Agency. Prepare Tax Returns for Someone Who Died – What Returns You Need to File
Filing this return is never mandatory. It exists as a planning tool: moving eligible income off the final return and onto a separate return gives you a second set of personal tax credits (basic personal amount, age amount, and others) that can shelter that income. For a deceased person with meaningful uncollected income, the saving can reach thousands of dollars. Capital gains do not qualify.
The rights or things return is due by the later of one year after the date of death, or 90 days after CRA mails the Notice of Assessment for the final T1.
The T3 Trust Return for the Estate
Once the date-of-death returns are handled, the estate itself becomes a separate taxpayer. Income earned after the date of death — bank interest, rent from properties the estate still holds, dividends on undistributed shares — belongs to the estate and is reported on a T3 Trust Income Tax and Information Return.4Canada Revenue Agency. T3 Trust Guide – 2025 Capital gains from selling estate assets during administration also go here.5Canada Revenue Agency. Who Should File – Filing a Trust T3 Return
A T3 is required whenever the estate earns more than $500 in total income, disposes of capital property, or distributes income to a beneficiary. Even modest bank interest during a long administration can push the estate over that threshold. The T3 must be filed within 90 days after the estate’s tax year-end.6Canada Revenue Agency. When to File – Filing a Trust T3 Return Estates that qualify as a Graduated Rate Estate can pick a non-calendar fiscal year-end tied to the date of death; other trusts must use December 31.
Graduated Rate Estate Designation
For the first 36 months after death, the estate can qualify as a Graduated Rate Estate if it meets four conditions: it is a testamentary trust (funded only as a consequence of the death), it designates itself as a GRE on its first T3, it provides the deceased’s Social Insurance Number, and no other estate claims the designation for the same individual.7Justice Laws Website. Income Tax Act RSC 1985, c. 1 (5th Supp.) – Section 248
The benefit is substantial. A GRE is taxed at graduated rates, the same progressive brackets that apply to individuals, rather than the flat top marginal rate imposed on all other trusts. For an Ontario estate in 2026, that top combined rate is over 53%. An estate earning $50,000 in a year is dramatically better off at graduated rates than having every dollar taxed at the top bracket. The designation must be made on the first T3; you cannot go back and add it later, and missing it forfeits the advantage permanently.
The Ontario Estate Information Return
Separate from the CRA filings, Ontario requires anyone who receives a Certificate of Appointment of Estate Trustee (the probate certificate) to file an Estate Information Return with the Ministry of Finance.8Government of Ontario. Ontario Code – Estate Administration Tax Act, 1998 The return is required even if the estate is worth $50,000 or less and no estate administration tax is owing.9Ministry of Finance. Guide Estate Information Return Estate Administration Tax Act, 1998
This filing is about asset values at the date of death, not income. Its purpose is to let the Ministry verify that the correct estate administration tax was paid when the probate certificate was issued. You list and value every asset that formed part of the probate application: real property, bank accounts, investments, vehicles, personal property. Debts are not deducted. Only encumbrances registered against real property, such as a mortgage, reduce the reported value.
The return must be received by the Ministry of Finance within 180 calendar days after the probate certificate is issued.10Ministry of Finance. Guide Estate Information Return Estate Administration Tax Act, 1998 It can be submitted online, or sent by mail, courier, or fax to the Ministry office in Oshawa.
How the Tax Is Calculated
Estates valued at $50,000 or less pay no estate administration tax. Above that, the tax is $15 for every $1,000 (or part thereof) of estate value.11Government of Ontario. Estate Administration Tax A $500,000 estate produces $7,500 in tax. Payment is made when applying for the probate certificate; the Estate Information Return then lets the Ministry confirm the figure.
If the Ministry decides assets were undervalued or omitted, it can reassess. Failing to file, or making false or misleading statements, is an offence punishable by a fine of at least $1,000 (up to twice the tax payable if that amount exceeds $1,000), imprisonment of up to two years, or both.8Government of Ontario. Ontario Code – Estate Administration Tax Act, 1998 Formal appraisals for real estate and business interests are the practical protection against reassessment.
Assets That Bypass Probate
Not every asset the deceased owned counts toward the probate value. Jointly held property with a right of survivorship passes directly to the surviving owner. Registered accounts like RRSPs, RRIFs, and TFSAs with a named beneficiary go to that person. Life insurance proceeds payable to a named beneficiary also fall outside the estate. These assets don’t appear on the probate application and don’t attract estate administration tax. They may still trigger tax on the final T1, however. RRSPs and RRIFs in particular are deemed disposed of at fair market value on death unless rolled to a qualifying recipient.
Deadlines at a Glance
- Final T1 return: April 30 of the year following death, or June 15 if the deceased or surviving spouse was self-employed (balance still due April 30). If death occurs in November or December, the deadline is six months after the date of death.
- Rights or things return: the later of one year after death, or 90 days after the mailing date of the Notice of Assessment for the final T1.
- T3 trust return: within 90 days after the estate’s tax year-end.6Canada Revenue Agency. When to File – Filing a Trust T3 Return
- Ontario Estate Information Return: within 180 calendar days after the Certificate of Appointment is issued.10Ministry of Finance. Guide Estate Information Return Estate Administration Tax Act, 1998
Missing a CRA deadline triggers late-filing penalties and interest. Missing the Ontario return deadline is a provincial offence with its own penalty structure. Marking all four dates at the start of the administration prevents the scramble that produces mistakes.
Getting a Clearance Certificate Before Distributing
Before paying out the remaining estate to beneficiaries, the trustee should apply to CRA for a clearance certificate.12Canada Revenue Agency. After You File – Prepare Tax Returns for Someone Who Died The certificate confirms that all taxes, interest, and penalties have been paid, or that CRA has accepted security for the amount. Application only becomes possible after you have received Notices of Assessment for all filed returns and paid any outstanding balances.
Distributing without a clearance certificate is legally risky. If CRA later finds unpaid tax, the trustee is personally liable up to the value of the assets that were distributed. Processing can take several months, but the certificate is what closes the estate’s tax file with certainty.
