Form TP-646: Quebec estate income tax return

What form TP-646 is for

At the time of death, the patrimony becomes an estate — which, for tax purposes, is treated as a trust distinct from the deceased. Until the liquidation is complete, all income generated by that patrimony is taxable in the estate.

TP-646 is used to report this income to Revenu Québec: bank interest, rent from a property, dividends from investments, capital gains on the sale of an asset, and so on. It is the Quebec counterpart of the federal T3 return filed with the Canada Revenue Agency.

This return is distinct from the deceased’s final return (TP-1), which covers the person’s income up to the date of death. TP-646 covers the period after the death.

When the liquidator must file TP-646

TP-646 must be filed each year the estate generates enough income to cross the thresholds set in the Quebec Taxation Act. Current thresholds are updated periodically and published on the Revenu Québec website.

The most common triggers:

• The estate holds investments that generate interest or dividends.
• The estate receives rent from a property awaiting sale or transfer.
• An asset is sold and triggers a capital gain for the estate.
• Employment or pension income is received after death in the estate’s name.

If the estate generates no income (frequent when assets are quickly distributed), no TP-646 is required.

Who must file it

The liquidator of the estate is responsible for filing TP-646 and paying any resulting tax, under the general rules of the administration of the property of others (articles 1351 et seq. of the Civil Code of Quebec) and their accounting duties (articles 819-822 CCQ).

For complex estates, the liquidator may mandate an accountant, notary or tax specialist to prepare the return. Their fees are an admissible administration expense and appear in the final account.

Where to obtain the official form and guides

Revenu Québec publishes the up-to-date form and the filing guide on its official site:

• Revenu Québec — Income tax return of a trust (TP-646)

The site lists the current thresholds, deadlines and any schedules that may need to be attached.

Deadlines and consequences of late filing

TP-646 is generally due within 90 days after the end of the estate’s fiscal year. The liquidator may choose the estate’s fiscal year at the first filing, which has a strategic impact on overall taxation.

Late filing or non-filing exposes the estate to:

• Penalties for late filing.
• Interest on amounts owed.
• Personal liability of the liquidator if assets were distributed to the heirs before obtaining the clearance certificate (form MR-14.A).

For this reason, tax returns should be filed before any distribution to the heirs.

Related steps in the liquidation

TP-646 is part of a chain of tax obligations the liquidator must follow in order:

1. Deceased’s final return (Quebec TP-1 + federal T1).
2. Annual estate returns (TP-646 + federal T3) as long as the estate exists.
3. Apply for the MR-14.A clearance from Revenu Québec and federal TX19 before distributing to the heirs.
4. Final account under the Civil Code (articles 821-822 CCQ).
