Cross-Border Gift Tax: How Canada and the US Tax Gifts Between Family Members in Different Countries

Canada and the US handle gifts in fundamentally different ways. The US has a gift tax: when you give property or money to someone, the donor (not the recipient) may owe tax on the transfer. Canada has no gift tax, but it achieves a similar result through deemed disposition rules (you are treated as having sold the property at FMV when you give it away, triggering capital gains tax) and attribution rules (income earned on the gifted property may be taxed back to the donor). When a gift crosses the border, both systems can apply to the same transfer, and the reporting obligations multiply.

How does the US gift tax work?

The US gift tax applies to the donor, not the recipient. When a US person (citizen or resident) gives property or money to anyone (other than a spouse who is a US citizen), the gift is potentially subject to gift tax.

Annual exclusion: The first $19,000 (2025, indexed for inflation) per recipient per year is excluded from gift tax. A married couple can give $38,000 per recipient per year ($19,000 each, or $38,000 with gift-splitting on Form 709). No gift tax return is required for gifts within the annual exclusion (unless gift-splitting is elected, which requires Form 709 regardless of amount).

Lifetime exemption: Gifts above the annual exclusion reduce the donor’s lifetime unified credit. The unified credit for 2025 shelters $13.99 million of cumulative lifetime gifts and estate transfers. A US person who gives $100,000 to a child uses $81,000 of the lifetime exemption ($100,000 minus $19,000 annual exclusion). No gift tax is owed until the cumulative lifetime gifts exceed $13.99 million.

Gift tax rate: 40% on gifts exceeding the lifetime exemption. In practice, very few people owe gift tax because the $13.99 million exemption is so large. The One Big Beautiful Bill Act made this exemption permanent at $15 million for 2026, eliminating the sunset that would have dropped it to approximately $7 million.

Gifts to non-citizen spouses: The unlimited marital deduction (which allows unlimited tax-free gifts between US-citizen spouses) does not apply to gifts to a non-citizen spouse. Instead, the annual exclusion for gifts to a non-citizen spouse is $190,000 (2025). Gifts above this amount use the donor’s lifetime exemption.

Reporting: Gifts above the annual exclusion (or any gift requiring gift-splitting or involving certain trusts) are reported on Form 709 (United States Gift Tax Return), due April 15 of the year following the gift.

How does Canada handle gifts?

Canada has no gift tax. A gift is not a taxable event for the recipient. But two rules ensure the donor does not escape tax:

Deemed disposition (ITA 69(1)(b)): When a taxpayer disposes of property by way of gift, the taxpayer is deemed to have received proceeds equal to the FMV of the property at the time of the gift. If the property has accrued gains, the donor pays capital gains tax on the deemed proceeds minus the adjusted cost base. This applies to gifts of appreciated property (stocks, real estate, art) but not to gifts of cash (cash has no gain).

Attribution rules: When a taxpayer transfers property to a spouse (ITA 74.1) or a related minor child (ITA 74.2), any income or capital gains earned on the transferred property is attributed back to the transferor (the donor). This prevents a high-income spouse from gifting investments to a low-income spouse or child to shift the tax on investment income.

The attribution rules have exceptions. They do not apply to transfers at FMV (a genuine sale, not a gift), to transfers to adult children (over 18), or to income earned on reinvested income (the “second generation” income). The prescribed-rate loan strategy (ITA 74.5(2)) can avoid attribution: the high-income spouse lends money to the low-income spouse at the CRA prescribed rate, the low-income spouse invests the loan proceeds, and only the interest on the loan is attributed back (not the investment returns, as long as the interest is paid by January 30 of the following year).

What happens when a US person gives a gift to a Canadian?

A US citizen or resident who gives a gift to a Canadian resident faces US gift tax rules on the donor side. The annual exclusion ($19,000) and lifetime exemption ($13.99 million) apply. If the gift exceeds the annual exclusion, Form 709 is required.

The Canadian recipient owes no Canadian tax on receiving the gift (Canada has no gift tax, and a gift received is not income). But if the gift is from a non-arm’s length person (like a parent), the Canadian recipient’s cost base for the property is the donor’s cost base (for capital gains purposes), not the FMV. This means any gain that accrued before the gift will be taxed when the Canadian recipient eventually sells the property.

If the US donor is also a Canadian resident (a US citizen living in Canada), the Canadian deemed disposition rule also applies to the donor, triggering Canadian capital gains tax on the transfer.

What happens when a Canadian gives a gift to a US person?

A Canadian resident who gives a gift to a US person faces Canadian deemed disposition rules (capital gains on appreciated property) and potentially the attribution rules (if the gift is to a spouse or minor child).

The US recipient owes no US income tax on receiving the gift (gifts are excluded from income under IRC 102). But if the gift is from a “foreign person” (non-US person) and exceeds $100,000 in a calendar year, the US recipient must report it on Form 3520, Part IV. The reporting threshold is $100,000 aggregate from a single foreign person (or from related foreign persons treated as one).

Failure to report a foreign gift on Form 3520: 5% of the gift per month, up to 25% of the total gift value. For a $200,000 gift, the maximum penalty is $50,000. This penalty applies even though no tax is owed on the gift itself. It is purely a reporting penalty.

What about gifts of cash?

Cash gifts are simpler because there is no capital gain (cash has no ACB or basis issue):

• US donor to Canadian recipient: The US donor uses the annual exclusion ($19,000) and lifetime exemption. No Canadian tax consequences for the recipient.
• Canadian donor to US recipient: No Canadian tax on the donor (cash has no gain, so deemed disposition produces no tax). The US recipient reports on Form 3520 if the aggregate exceeds $100,000.
• US citizen in Canada giving cash to a Canadian spouse: The US gift tax non-citizen spouse annual exclusion is $190,000 (2025). Below that amount, no Form 709 required. No Canadian tax consequences on either side (cash gift, no gain, attribution rules do not create income from cash sitting in a bank account; they apply to investment income earned on the gifted amount).

What about gifts of US real property?

A gift of US real property (a Florida condo, for example) triggers US gift tax rules on the donor. If the donor is a non-citizen non-resident (a Canadian who owns the condo), the gift of US-situs real property is subject to US gift tax even though the donor is not a US person, because US real estate is US-situs property under IRC 2511. Non-citizens get no lifetime exemption for gifts (unlike the estate tax, where the treaty provides a prorated credit). The only exclusion is the $19,000 annual exclusion, which does not help for a property worth hundreds of thousands of dollars.

This means a Canadian who gives a US condo to a child faces US gift tax at 40% on the value above $19,000, with no lifetime exemption. This is one of the most punitive cross-border gift scenarios and should be avoided through planning (sell the property and gift the cash, or transfer the property at death where the treaty prorated credit applies).

The Canadian side: the donor faces deemed disposition at FMV, triggering Canadian capital gains tax on the accrued gain.

What about gifts between spouses?

Both spouses are US persons: The unlimited marital deduction applies. No gift tax, no Form 709 (unless one spouse is not a citizen, in which case the $190,000 enhanced annual exclusion applies).

US person to Canadian spouse (not a US citizen): The $190,000 enhanced annual exclusion applies. Gifts above this amount use the US donor’s lifetime exemption. On the Canadian side, the attribution rules apply: income earned on the gifted property is attributed back to the US donor for Canadian tax purposes (ITA 74.1). This can create a mismatch where the US taxes the Canadian spouse on the investment income and Canada attributes the same income back to the US donor.

Canadian person to US person spouse: No Canadian gift tax. Deemed disposition applies if the gift is appreciated property (but the spousal rollover under ITA 73(1) allows the transfer at cost, not FMV, deferring the gain until the recipient spouse sells). The US recipient reports on Form 3520 if the aggregate exceeds $100,000.
