Final T1 return for deceased in Canada

What the final T1 return is

When a Canadian dies, the tax system does not stop with them. Someone has to file a last return covering the part of the year the person was alive, and that return is the final T1. It reports the deceased's income from January 1 of the year of death up to the date of death, the same way a normal return reports a full calendar year, but for a partial year ending at death. On top of that ordinary income, the final return carries the deemed disposition, the rule that treats the deceased as having sold their capital property at fair market value immediately before death, which is where accrued capital gains are taxed. The size of that deemed-disposition hit on a Florida property is largely set years earlier, at purchase; the estate-planning-before-buying guide shows how the ownership choice made on day one shapes the final return.

The person responsible for filing is the deceased's legal representative: the executor named in the will, the court-appointed administrator if there is no will, or, in Quebec, the liquidator of the succession. That representative signs and files the final T1, pays the tax owing from the estate, and is the point of contact with the CRA for the deceased's affairs.

The filing deadline, which depends on the date of death

The deadline for the final T1 is not a single date. It follows a death-window rule that gives the representative more time when death occurs late in the year. In the general case, if the person died between January 1 and October 31, the final return is due on April 30 of the following year, the same as an ordinary return. If the person died between November 1 and December 31, the final return is instead due six months after the date of death, which pushes the deadline past the usual April 30.

A different timetable applies when the deceased or their spouse or common-law partner was carrying on a business. In that self-employed case, the final return is generally due June 15 of the following year for deaths up to December 15, and six months after death for deaths between December 16 and December 31. Any balance of tax owing, however, is generally due earlier than the filing date, so it is prudent to estimate and pay the tax even while the return is being prepared. Late filing with a balance owing triggers a penalty of 5 percent of the balance plus 1 percent for each full month the return is late, up to 12 months.

What goes on the final return

The final T1 combines two things. First, it reports the ordinary income the person earned while alive in the year of death: employment income to the date of death, pension and investment income received, and so on. Second, it reports the deemed disposition, which converts the accrued gains on the deceased's capital property into a realized capital gain in the year of death. Half of that gain, at the 50 percent inclusion rate, is added to taxable income.

For a Canadian who owned a Florida condo, the accrued gain on that condo is part of the deemed disposition reported here, translated into Canadian dollars at the relevant exchange rates. The mechanics of how that cross-border gain is computed, and how it interacts with the US step-up in basis, are covered in the guide on the deemed disposition versus the US step-up. The final T1 is simply where that gain lands and where the Canadian tax on it is calculated.

Quebec residents: a separate provincial return

Quebec administers its own income tax separately from the rest of Canada, so a deceased person who was a resident of Quebec is not fully covered by the federal T1 alone. In addition to the final federal T1 filed with the Canada Revenue Agency, the legal representative (the liquidator of the succession) must file a separate Quebec provincial final return, the TP-1 income tax return, with Revenu Quebec. The two returns are filed in parallel: the federal T1 settles the federal tax, and the Quebec TP-1 settles the Quebec provincial tax for the part of the year the person was alive. Residents of every other province file only the federal T1, because the CRA collects their provincial tax on the same return.

Optional separate returns that can lower the tax

Beyond the single final return, the law lets a representative file one or more optional separate returns for certain kinds of income the deceased had at death. The best known is the return for rights or things, which covers amounts the person was entitled to at death but had not yet received, such as certain unpaid salary, accrued bond interest, or declared but unpaid dividends. Reporting these on a separate optional return rather than on the main final return can let the estate claim certain personal tax credits more than once and apply the lower graduated rates again, which can reduce the overall tax.

Whether the optional returns help depends entirely on the deceased's specific income, and they come with their own elections and deadlines. They are a genuine planning tool rather than a formality, and a Canadian estate with meaningful income at death should have an accountant test whether filing them produces a saving. Done well, they are one of the few ways to reduce the tax on a final return; ignored, they simply leave money on the table.

The clearance certificate: do not distribute without it

The step most representatives wish they had known about is the clearance certificate. Before the estate's assets are distributed to the beneficiaries, the legal representative should ask the CRA for a clearance certificate, on Form TX19, confirming that all amounts the deceased and the estate owe have been paid or secured. If the representative distributes the estate without one and tax later turns out to be owing, the representative can be held personally liable for the unpaid amount, up to the value distributed.

For a cross-border estate with a Florida property, this matters because the deemed-disposition tax can be substantial and is not always obvious to a family focused on the foreign asset. The prudent sequence is to file the final return, settle the tax, obtain the clearance certificate, and only then distribute. Skipping the certificate to speed up the distribution is a common and avoidable way for an executor to take on personal risk.

Deadline at a glance

Any balance of tax owing is generally due before the filing date, so estimate and pay early even if the return itself is filed later.

Worked example: computing the deadline

Suppose a retired Canadian dies on March 10, 2026, owning a Florida condo. Because the death falls between January 1 and October 31, the final T1 is due April 30, 2027, the ordinary deadline. The representative reports the deceased's income from January 1 to March 10, 2026, plus the deemed disposition of the condo, computed in Canadian dollars, and pays the resulting tax from the estate.

Now change the date to December 5, 2026. Because the death falls between November 1 and December 31, the final return is instead due six months after death, that is, June 5, 2027, rather than April 30. The later death date buys the representative extra time, but the tax on the deemed disposition is the same; only the deadline shifts. In both cases, the representative should obtain the clearance certificate before distributing the condo or its proceeds.

Common mistakes

The errors here are mostly about timing and personal liability.

The first is missing the death-window deadline, assuming every final return is due April 30 when a late-year death pushes the deadline to six months after death, or, for a self-employed person, assuming June 15 when the rule differs. The second is paying late: the balance owing is generally due before the filing date, and a late balance attracts the 5 percent plus 1 percent per month penalty plus interest. The third is forgetting the deemed disposition, filing a final return that reports only ordinary income and omits the accrued gain on the Florida property. The fourth, and the most expensive personally, is distributing the estate without a clearance certificate, which can leave the executor on the hook for unpaid tax. The fifth is ignoring the optional returns, which can lower the tax for an estate with rights or things at death.

Checklist: filing a final T1 for a deceased Canadian

1. Confirm who the legal representative is and gather the deceased's tax records.
2. Determine the filing deadline from the date of death, using the death-window rule and the self-employed variant if it applies.
3. Report income from January 1 to the date of death.
4. Report the deemed disposition, including the accrued gain on any US property, translated into Canadian dollars.
5. Test whether optional separate returns (such as rights or things) reduce the tax.
6. Estimate and pay the balance owing early to avoid penalties and interest.
7. Apply for a clearance certificate on Form TX19 and wait for it before distributing the estate.
8. For US property, coordinate any US estate tax and foreign tax credits with a cross-border professional.

FAQ

When is the final T1 due?

It depends on the date of death. For a death between January 1 and October 31, it is due April 30 of the following year. For a death between November 1 and December 31, it is due six months after the date of death. A self-employed deceased generally has until June 15, with a six-month rule for very late-December deaths.

Who has to file it?

The deceased's legal representative: the executor under the will, the administrator if there is no will, or the liquidator in Quebec. That person signs the return, pays the tax from the estate, and deals with the CRA.

Is the Florida property reported on the final T1?

Yes. The accrued gain on the Florida property is part of the deemed disposition reported on the final return, converted into Canadian dollars. The Canadian capital gains tax on that gain is calculated here, separately from any US estate tax on the same property.

What is a clearance certificate and do I need one?

It is a CRA confirmation, requested on Form TX19, that the deceased's and the estate's taxes are paid. You should obtain it before distributing the estate, because distributing without it can make you personally liable for unpaid tax up to the value you handed out.

Can I reduce the tax on the final return?

Sometimes, through optional separate returns for income such as rights or things, which can duplicate certain credits and graduated rates. Whether they help depends on the deceased's specific income, so have an accountant test them.

Is there a separate return for income earned after death?

Yes. Income the estate earns after the date of death is generally reported on a T3 trust return for the estate, often as a graduated rate estate, which is distinct from the deceased's final T1. The final T1 stops at the date of death.
