Inherited a House in Canada? Live In, Rent, or Sell: The 2026 Tax Math on an $850K Home

A Scarborough bungalow bought for $260K in 1996 and worth $850K when the last parent dies generates a $590K capital gain on paper — and in most cases, $0 of tax. The principal residence exemption wipes the gain on the terminal return, and you inherit the house with a fresh $850K cost base. That's the part almost every beneficiary gets right. The part they get wrong is what happens next: whether you move in, rent it out, or sell decides whether the next $130K of growth is tax-free, taxed at up to 26.76%, or never accrues at all. Here's the math on all three paths.

The Starting Point All Three Paths Share: The Date-of-Death Reset

Under section 70(5) of the Income Tax Act, the deceased is deemed to have sold the house at fair market value on the date of death. Any accrued gain lands on their terminal return at the current 50% inclusion rate — the tiered increase proposed in 2024 was cancelled in March 2025 and never took effect (the full history is in our guide to the 2026 inheritance tax law changes). If the house was the deceased's principal residence for every year they owned it, the exemption eliminates the gain entirely; the executor claims it on Form T1255.

What you receive is a property with an adjusted cost base equal to its date-of-death value. This is the single most misunderstood number in inherited real estate: your parents' $260K purchase price is irrelevant to you. Your tax clock starts at $850K.

Path 1: Move In — the Tax-Free Path With One Expensive Catch

If you move into the inherited house and designate it your principal residence, every dollar of growth from the date of death onward is tax-free when you eventually sell. On paper this is the cleanest outcome in Canadian tax: a stepped-up cost base plus the principal residence exemption going forward.

The catch is section 40(2)(b): one property per family unit per year. You, your spouse or common-law partner, and your unmarried minor children collectively get one principal residence designation for each calendar year. If you already own a home in Mississauga and move into the inherited Scarborough house while keeping the first one, you are not doubling your exemption — you are choosing, year by year, which property's growth is sheltered and which accrues a taxable gain.

How to choose when you own two properties

Designate the property with the higher expected gain per year of ownership, not the one you happen to sleep in. A beneficiary whose own condo is appreciating at $15K/year while the inherited detached house appreciates at $40K/year should generally sell the condo (using the exemption on it up to the sale, with the "plus 1" rule bridging the overlap year) and designate the house going forward. Keeping both long-term guarantees somebody pays capital gains eventually — the only question is on which property and at what size.

One more scenario worth naming: if you were already living in the house with your parent — the classic adult-child caregiver arrangement — nothing about the deemed disposition evicts you. The estate claims the exemption to the date of death, you take the stepped-up base, and your own designation clock starts immediately. If that's you, the answer is genuinely reassuring: keep living there, designate it, and the tax outcome is as good as it gets.

Path 2: Rent It Out — Income Now, a Tax Bill Later, and the CCA Trap

Renting the house converts it to an income property, and two separate tax meters start running.

Meter one: rental income. Net rent — gross rent minus property tax, insurance, interest, repairs, condo fees — is taxed at your full marginal rate on Form T776. In Ontario in 2026, a beneficiary with $120K of taxable income pays roughly 43.41 cents of each additional rental dollar; at the top bracket it is 53.53 cents. Suppose the Scarborough house nets $24,000/year after costs: that is roughly $10,400 of tax annually for the $120K earner. Rent gets none of the favourable treatment capital gains get.

Meter two: capital growth. Every dollar the property appreciates beyond the date-of-death value is now a taxable capital gain at 50% inclusion, because a rental cannot be your designated principal residence. Hold it five years while it grows from $850K to $980K, and the $130K gain adds $65K to your taxable income in the year you sell — roughly $28,200 of tax in the 43.41% bracket, up to about $34,800 at Ontario's top rate (26.76% of the full gain). Split between two siblings, each reports half.

The change-of-use elections most beneficiaries have never heard of

The Income Tax Act treats switching a property between personal and income use as a deemed sale at fair market value — even though no money changes hands. Two elections control the timing, and using them well is worth real money:

• Subsection 45(2) — you lived in it, now you want to rent it. A signed letter filed with your return for the year of the change defers the deemed disposition and lets you keep designating the house as your principal residence for up to four more years while it is rented — provided you designate no other property and stay a Canadian resident. For a beneficiary who moves in, then gets relocated for work two years later, this election keeps the exemption alive through the rental years.
• Subsection 45(3) — you rented it, now you want to move in. The mirror election defers the deemed disposition at move-in and lets you designate the property as your principal residence for up to four years before you occupied it. Filed by the earlier of 90 days after a CRA demand or the return deadline for the year you finally sell.

Path 3: Sell — Usually the Least Taxed and the Most Underrated

Because your cost base reset at death, a sale within months typically produces almost no taxable gain: an $850K house sold for $860K nine months later, minus roughly $40K of realtor commission and legal costs, nets a capital loss on paper. The tax anxiety most families feel about selling an inherited home is aimed at a gain the estate already extinguished.

Two selling questions actually matter:

• Estate sale or personal sale? If the executor sells before distributing, the (small) post-death gain or loss is reported on the estate's T3 return; sell after transfer and it lands on your personal return. Where a small post-death loss exists, realizing it in the estate's first taxation year can offset terminal-return gains — a timing decision worth an hour with the estate accountant before listing. Either way, probate comes first: no certificate, no title transfer, no closing.
• The flipping rule does not catch you. The residential anti-flipping rule deems gains on housing held under 365 days to be fully taxable business income — but dispositions arising from the death of the taxpayer or a related person are explicitly excepted. Selling in month six is still a capital disposition from the stepped-up base.

For the Ontario mechanics — probate documents, listing while the estate is open, the step-by-step timeline from death certificate to closing — the selling an inherited house in Ontario guide covers the province-specific detail. And once proceeds land, the deployment question (TFSA room first, then FHSA, then the non-registered overflow) is its own decision — mapped in how to deploy an inheritance in Canada.

The Three Paths, Side by Side

How I'd Actually Decide

Strip out the sentiment and the decision usually reduces to two questions. First: would you buy this house today at its appraised value? Keeping it — as a home or a rental — is economically identical to buying it at $850K, because that is the capital you are choosing not to redeploy. If the honest answer is no, sell; the stepped-up base makes this the cheapest moment you will ever have to exit. Second, if you keep it: does it beat what the money would earn elsewhere, after tax? A rental netting $24K on $850K of trapped equity is a 2.8% pre-tax yield with fully-taxable income and a taxable-growth meter running — the appreciation has to carry the case.

I'll also push back on the default most families drift into: renting it out "for now" because nobody can face a decision. That path collects the worst of everything — landlord obligations, fully-taxed income, a growing embedded gain, and, if someone claims CCA along the way, a burned election. The exceptions are real: a house with genuinely strong rental economics, or a sibling who will plausibly move in within the four-year s. 45(3) window. But "we'll figure it out later" is a tax strategy, and it is the most expensive one on this page. A planned outcome beats a drifted one — pick a path within the first year, while the stepped-up base still makes every option cheap to execute.
