Donating Across the Border: How Article XXI Lets a Canadian Deduct a US Charity, and Vice Versa, With Limits

A Canadian who donates to a US charity gets no Canadian donation credit under domestic law, because the recipient is not a registered Canadian charity. An American who donates to a Canadian charity gets no US deduction, because the recipient is not a US 501(c)(3). Article XXI of the treaty changes both results, but only up to the donor's income from the other country, and it adds one broader rule: donations to a university the donor or a family member attended are creditable against all income.

Key takeaways

• Canadian donor, US charity: the donation qualifies for the Canadian donation credit under Article XXI, limited to the donor's US-source income for the year (with the usual 75% of net income cap applied to that US-source income). Donations to a US university the donor or a family member attended qualify against all income.
• US donor, Canadian charity: the donation is deductible on the US return under Article XXI, limited to the donor's Canadian-source income, with the same university exception. The Canadian charity must be one that would qualify as a 501(c)(3) if it were US-based.
• Cross-border filers with income in both countries often have room under the limits; single-country donors usually do not.
• Donor-advised funds and cross-border foundations can route gifts to qualify domestically.
• Canada's credit is a non-refundable credit at 15% federally on the first $200 and 29% (33% for top-bracket donors) above, plus provincial credits; the US deduction is an itemized deduction at the donor's marginal rate, subject to AGI limits.

The Canadian side

Canadian residents claim donation credits for gifts to qualified donees: registered Canadian charities, Canadian municipalities, the UN, certain foreign universities on a prescribed list, and, under the treaty, US charities. The treaty provision allows the credit for gifts to a US organization that would be a registered charity if it were Canadian, but caps the eligible amount at the donor's US-source income. A Canadian with US rental income, US employment income, or US dividends has room; a Canadian with no US income has none.

The university exception: gifts to a US college or university at which the donor or a member of the donor's family is or was enrolled are creditable against all income, not just US-source income, without regard to the treaty limit. Many US universities are also on Canada's prescribed list of foreign universities, which produces the same result domestically.

The US side

US taxpayers who itemize can deduct gifts to Canadian charities under Article XXI, limited to Canadian-source income, provided the Canadian charity is a registered charity that would qualify under section 501(c)(3). The same university exception applies for Canadian universities the donor or family attended. Americans living in Canada with Canadian employment income have substantial room; Americans in the US with no Canadian income have none.

The US deduction is subject to the usual AGI limits (60% for cash to public charities) and is available only to itemizers; since the 2017 standard deduction increase, most taxpayers do not itemize, and the cross-border deduction matters mainly to high donors.

Structures that work

• Canadian-registered affiliates. Many large US charities and universities have Canadian registered "friends of" organizations; a gift to the Canadian affiliate is fully creditable in Canada regardless of US-source income.
• US 501(c)(3) affiliates of Canadian charities. The reverse structure for Americans.
• Donor-advised funds. A Canadian donor-advised fund can make grants to qualified foreign charities under CRA rules; a US donor-advised fund can grant to foreign charities through equivalency determination or expenditure responsibility.
• Gifts of appreciated securities. Canada eliminates the capital gain on gifts of publicly listed securities to registered charities; the US allows a deduction at fair market value without recognizing the gain. Cross-border gifts of securities to a foreign charity do not get the Canadian gain elimination unless the recipient is a qualified donee.

Worked example

A Toronto executive with $40,000 of US rental income and a US-citizen spouse wants to give $25,000 to a Boston hospital foundation and $10,000 to her US alma mater.

• Hospital. Creditable in Canada under Article XXI up to 75% of $40,000 US-source income: $30,000 room; the full $25,000 qualifies. Canadian credit roughly $11,000 at Ontario rates.
• University. Creditable against all income under the university exception; the full $10,000 qualifies without using US-source-income room.
• US spouse. If the spouse itemizes on a US return, the gifts are deductible domestically as gifts to US charities.
• Alternative. If the hospital has a Canadian registered affiliate, giving through it removes the US-source income limit entirely.

Practitioner note

Cross-border donors rarely check whether the recipient has a registered affiliate on their side of the border, and it is the single easiest way to make a gift fully creditable. We check before the gift is made; afterward there is nothing to do but apply the treaty limit.
