Tax on Selling an Inherited Property in Ontario: What Beneficiaries Need to Know

Inheriting a property can feel like a gift — but once you decide to sell, the tax questions arrive quickly. What did you "pay" for it? Do you owe capital gains? Did the estate already pay tax? Many Ontario beneficiaries are surprised to learn that most of the tax burden on an inherited property is handled at the estate level, not when they eventually sell. Understanding how this works can help you plan, avoid double-counting, and keep the right records from day one.

The short answer: the tax on selling inherited property in Ontario depends on two events — what happened at the moment of the deceased's death, and what happens when you as the beneficiary later sell. These are separate tax events, and the rules treat them accordingly.

This guide explains both in plain language. It is not a substitute for advice from a licensed tax professional or estate lawyer — the rules are fact-specific and tax rates can change — but it will give you a solid foundation before those conversations.

What Happens at Death: The Deemed Disposition

Under the Income Tax Act (Canada), a person is treated as having sold all of their capital property at fair market value (FMV) immediately before they die. This is called a deemed disposition. The estate does not literally sell the property, but the tax system treats it as if the deceased did.

What This Means in Practice

• The deceased's terminal T1 return (the final personal income tax return filed by the estate) reports any capital gain on the property.
• The gain is calculated as the FMV at the date of death minus the deceased's original adjusted cost base (ACB) — essentially what they paid for it plus eligible improvements.
• A portion of that gain is included in the deceased's income for the year of death. The exact inclusion rate is set by the federal government and can change; confirm the current rate with the CRA or an accountant before filing.
• The estate (or its executor) is responsible for this tax, not the beneficiary. It comes out of estate assets before distribution.

This is a critical distinction. The estate pays the capital gains tax on the property's growth up to the date of death. You, as the beneficiary, inherit the property with a clean slate.

The Beneficiary's Adjusted Cost Base: The Step-Up

When you receive the inherited property, your adjusted cost base is stepped up to the FMV at the date of death. This is sometimes called the "stepped-up ACB."

Why This Matters When You Sell

When you eventually sell the inherited property, your capital gain is calculated as:

Proceeds of disposition − your ACB (FMV at date of death) − selling costs = capital gain

You do not owe tax on the appreciation that occurred during the deceased's lifetime — that was already captured in the estate's terminal return. You are only responsible for tax on any increase in value from the date of death forward.

Example (illustrative only): If the property was worth $600,000 when you inherited it, and you sell it five years later for $700,000 (less $20,000 in real estate commissions and legal fees), your gain is roughly $80,000 — not $580,000. A portion of that $80,000 is included in your income for the year of sale; the rate is set by federal law, so confirm it with an accountant.

Spousal Rollovers: Deferring the Gain

There is an important exception when property passes from a deceased spouse or common-law partner to a surviving spouse or common-law partner. Under federal tax rules, the deemed disposition can be deferred — the property is treated as transferring at the deceased's ACB rather than FMV. This means no capital gain is triggered at death.

The surviving spouse inherits the original ACB. The gain is eventually recognized when the surviving spouse sells the property or passes away themselves. This rollover happens automatically unless the estate elects out of it (sometimes beneficial for planning purposes). An estate lawyer and tax advisor should review whether the automatic rollover is the right choice for the estate.

The Principal Residence Exemption (PRE): Can the Beneficiary Use It?

The Principal Residence Exemption can eliminate or reduce capital gains tax on the sale of a property that qualifies as your principal residence. If you inherit a property and move in and use it as your principal residence, you may be able to designate it as such for the years you actually lived there.

You cannot retroactively claim the PRE for years before you owned the property, and the PRE calculation is prorated to the number of years it was your qualifying principal residence versus total years of ownership since your step-up ACB date. Given the complexity of PRE designations on inherited properties, professional advice is strongly recommended before filing.

Multiple Beneficiaries and Co-Ownership

When two or more people inherit a property together, each co-owner holds an undivided interest. Each beneficiary's ACB is based on their proportionate share of the FMV at the date of death. When the property sells, each reports their proportionate share of the gain (or loss) on their own return. Disagreements about whether and when to sell can lead to co-ownership disputes — a topic worth addressing in an estate plan before problems arise.

Ontario-Specific Note: Probate Fees Are Not Income Tax

Ontario levies Estate Administration Tax (EAT) — commonly called probate fees — on the value of an estate that goes through the probate process. EAT is calculated on the total estate value and is paid by the estate. It is not income tax and is not a capital gains tax. It is a separate provincial fee and does not affect your ACB or your tax bill when you sell the property later. Many beneficiaries confuse the two; they are entirely different obligations under different legislation (Estate Administration Tax Act, 1998 for probate; the Income Tax Act for capital gains).

Practical Steps for Beneficiaries

• Get a professional appraisal at the date of death. This is the single most important step. A qualified appraiser's report establishes the FMV that becomes your ACB and the estate's deemed disposition value. Without it, you may face a CRA audit with no reliable number to support your position.
• Keep all records. Hold on to the appraisal, the probate documents, the estate's T1 terminal return and any T3 trust returns, and your own eventual sale records. These documents form the paper trail for any future CRA review.
• Track capital improvements. If you renovate or improve the property after you inherit it, those costs can be added to your ACB, reducing your eventual gain. Keep receipts.
• Confirm the current inclusion rate. The portion of a capital gain included in income is set by federal law and has changed before. Do not assume any specific number — check with the CRA or an accountant before filing in the year of sale.
• Work with both an estate lawyer and an accountant. The legal and tax sides of an inherited property intersect in ways that require both professionals. Getting advice early — ideally before the estate is distributed — prevents costly mistakes.
