Inheritance Tax Planning in Canada: What Your Estate Will Actually Owe

Leaving an inheritance in Canada does not trigger a government inheritance tax bill. It can still trigger a large one, just under a different name, and it lands on the deceased rather than the beneficiary. Deemed disposition treats everything they owned as sold at fair market value the moment before they died, and that capital gain shows up on their own final tax return, before anyone inherits a thing.

Inheritance tax planning is the work of managing that bill in advance, so it costs the estate as little as possible and lands on nobody unprepared.

The mechanism is called deemed disposition. The CRA treats a person as having sold all their capital property, non-registered investments, real estate other than a principal residence, business shares, at fair market value immediately before death. Any gain between what was paid and what it is worth becomes a capital gain on the deceased’s final, or terminal, tax return, taxed at the standard 50 percent inclusion rate.

A person who bought shares for $200,000 that are worth $500,000 at death has a $300,000 capital gain landing on that one return, all at once, with no ability to spread it across future years.

When capital property or registered accounts transfer to a surviving spouse or common-law partner, the deemed disposition rule does not apply. The property moves at its original cost, not its market value, so no capital gain is triggered at all. The same $500,000 in shares that would have created a $300,000 gain instead passes to the spouse at the original $200,000 cost base, with the tax deferred until the spouse eventually sells or dies without their own spousal rollover to lean on. This rollover applies automatically under the Income Tax Act unless the executor specifically elects out of it, and it covers both non-registered capital property and registered accounts.

RRSPs and RRIFs are treated even more harshly than other capital property when there is no spousal rollover. The entire account balance is included as income on the deceased’s final return, not just the growth. A $350,000 RRSP with no qualifying beneficiary can push that return into the highest tax bracket, and the estate can lose well over half of it to combined federal and provincial tax before anything reaches the people it was meant for.

Two exceptions soften this. A spouse or common-law partner named as beneficiary can roll the RRSP or RRIF directly into their own registered account, deferring tax until they withdraw it. A financially dependent child or grandchild, generally meaning their income was below the basic personal amount, or they depend on the deceased due to a mental or physical infirmity, may also qualify for a transfer, though the rules are narrower than for a spouse.

TFSAs work differently again. Naming a spouse as successor holder, not simply beneficiary, lets the account continue tax-free in their hands, growth and all. Naming anyone else as beneficiary pays out the balance tax-free as a lump sum, but the account itself ends there. Getting that one designation wrong, successor holder versus beneficiary, is a common and entirely avoidable mistake.

Probate fees are not income tax. They are a provincial charge to validate a will, calculated on the value of whatever passes through the estate, and they vary enormously by province.

Assets with a named beneficiary, RRSPs, RRIFs, TFSAs, life insurance, generally bypass probate entirely and are not included in this calculation, which is one more reason correct beneficiary designations matter beyond just the tax treatment itself.

Life insurance proceeds paid to a named beneficiary are received tax-free and bypass probate. Estates are often asset-rich and cash-poor at exactly the moment a large deemed-disposition tax bill comes due, particularly where a business, a cottage, or a concentrated investment portfolio makes up most of the value. A life insurance policy sized to cover the expected tax liability gives an estate the cash to pay that bill without forcing heirs to sell the asset itself under time pressure.

Inheritance tax planning in Canada is not about avoiding a tax that does not exist. It is about managing deemed disposition, structuring RRSP and TFSA beneficiary designations correctly, and accounting for probate before any of it becomes urgent.
