Claim credits to reduce your tax bill
There may also be certain credits available under the Canada-
US Tax Treaty to reduce the resulting tax liability in the year of
death, including a unified credit, a marital credit and a Canadian
credit for US estate taxes.
Unified Credit
For 2023, Canadians may be eligible for a unified credit of up to
US$5.11 million that can be applied against a tentative US
estate tax liability. This credit effectively shelters US$12.92 million
of a taxable estate. The unified credit must be pro-rated based on
the ratio of US situs assets to worldwide assets as follows:
US Situs Assets x Unified Credit =
Prorated Unified Credit Worldwide Assets**
** The denominator is based on US estate tax principles and includes amounts
such as the value of life insurance proceeds and a principal residence.
Marital Credit
In addition, a “marital credit” is also available that can almost
double the unified credit if US property is transferred to a spouse
upon death. The marital credit is limited to the lesser of:
– The pro-rated unified credit, or
– Tax otherwise payable on qualified property transferred to
a spouse
Where individuals who are married and transfer all US property
to a spouse upon death, then no estate tax should be payable,
as long as the value of the deceased’s taxable estate is
US$23.98 million or less.
Note that where assets are jointly held, the first joint tenant to die
is deemed to own 100% of the property, unless the executor can
show that the surviving joint tenant paid for their share with their
own money. This rule applies to property held as joint tenants
with right of survivorship but does not apply to property held as
tenants in common.
Canadian Credit for US Estate Taxes
You may be able to apply a credit for US estate taxes paid
against your Canadian federal income tax on US source income
in the year of death. This credit includes gains on the shares
of US corporations.
2023 US estate tax exclusion thresholds
US estate tax is calculated at graduated rates (see the Appendix)
on the fair market value of an individual’s “taxable estate” as
follows:
US Situs Assets:
US$60,000
If the value of your US situs assets is
US$60,000 or less upon death, you are
not liable for US estate tax, regardless of
the value of your worldwide assets.
If the value of your US situs assets is
greater than US$60,000 upon death,
your estate must file a US estate tax
return, even if no tax is payable.
Worldwide Assets:
US$12.92 million
If the value of your worldwide assets is
US$12.92 million or less when you die,
you are not liable for US estate tax,
regardless of the value of your US situs
assets. You still must file a US estate tax
return to claim Canada-US treaty
benefits if the value of your US situs
assets is greater than US$60,000.
US Situs Assets &
Worldwide Assets
If the value of your US situs assets is
greater than US$60,000 and the value
of your worldwide assets is greater than
US$12.92 million, you may have a US
estate tax liability when you die. You
must file a US estate tax return to claim
Canada-US treaty benefits of the Treaty
and calculate your tax liability.
Note: The estate tax exclusion (and unified credit) will return to
pre-2018 levels beginning January 1, 2026. The exclusion
amount will be reduced to US$5.49 million (from US$12.92
million) (adjusted for inflation).
The US estate tax return (Form 706-NA), along with any estate
tax payable, must be filed nine months after the date of death
(although a six-month extension to file the return is available).
The deadline to pay estate tax can also be extended, but interest
accrues while the amount remains unpaid.

Note that the basis of property held at death is adjusted to fair market value for US income tax purposes even if no estate tax is payable.
