Cross-border charitable giving: Canada and US

Donating to charity should be straightforward, but the moment the gift crosses the Canada-US border, the tax rules get complicated. Canada uses a non-refundable tax credit system for charitable donations. The US uses an itemized deduction. And neither country automatically recognizes the other’s charities for tax purposes.

The Canada-US Tax Treaty bridges some of that gap through Article XXI, but it comes with conditions that catch donors off guard. This guide breaks down how charitable giving works in each country, what the treaty does (and doesn’t do), and how to structure cross-border donations so you actually get the tax benefit you’re expecting.

How does Canada’s donation tax credit work?

Canada provides a non-refundable tax credit for donations to registered charities, calculated at tiered federal rates with additional provincial credits on top. The system rewards larger gifts with higher credit rates, and unused credits carry forward for five years.

Under ITA 118.1, the federal donation tax credit applies at three rates. The first $200 of annual donations earns a 15% credit. Amounts above $200 earn a 29% credit. If your taxable income puts you in the top bracket (above $235,675 for 2024), the rate on amounts over $200 bumps up to 33%.

Provincial credits add another layer. In Ontario, for example, you get 5.05% on the first $200 and 11.16% on the rest. Combined with the federal credit, a high-income Ontario donor effectively recovers about 50 cents on every dollar donated above $200. That’s a meaningful offset, though it’s a credit against tax owing, not a refund if you don’t owe enough.

There’s a ceiling. You can only claim donations up to 75% of your net income in any given year under ITA 118.1(1). Donations that exceed that limit carry forward for up to five years. In the year of death and the preceding year, the limit rises to 100% of net income, which often opens room to claim large bequests.

One thing people miss: the credit only applies to gifts made to “qualified donees,” a defined list that includes registered Canadian charities, the Crown, municipalities, and certain other entities. A US 501(c)(3) is not on that list by default, no matter how well-known the organization.

How does the US charitable deduction work?

The US treats charitable contributions as an itemized deduction on Schedule A, reducing taxable income rather than providing a direct credit against tax. You only benefit if your total itemized deductions exceed the standard deduction.

Under IRC 170, the deduction’s value depends on your marginal tax rate. A donor in the 37% bracket saves 37 cents per dollar donated. Someone in the 24% bracket saves 24 cents. This is structurally different from Canada’s credit system, where the rate is fixed regardless of your bracket (though Canada’s top-bracket 33% rate does add a bracket-dependent element).

AGI limits cap how much you can deduct in a given year. Cash donations to public charities are limited to 60% of AGI. Donations of capital gain property to public charities are limited to 30% of AGI. Gifts to private foundations face a 30% limit for cash and 20% for appreciated property. Excess donations carry forward for five years under IRC 170(d).

The standard deduction creates a practical threshold. For 2024, it’s $14,600 for single filers and $29,200 for married filing jointly. If your total itemized deductions (including charitable gifts, mortgage interest, state taxes, and so on) don’t exceed those amounts, your donations provide zero federal tax benefit. This is why “bunching” donations into alternating years has become a common strategy.

Similar to Canada, the deduction only applies to donations made to qualifying organizations, primarily 501(c)(3) entities. A Canadian registered charity doesn’t qualify unless the treaty opens the door.

What does Treaty Article XXI actually do?

Article XXI of the Canada-US Tax Treaty allows taxpayers in one country to claim tax benefits for donations made to charities in the other country, but only to the extent of income sourced from that other country. It’s a bridge, not a blanket pass.

Here’s how it works in practice. If you’re a US resident and you donate to a Canadian registered charity, you can claim that donation as a charitable deduction on your US return, but only up to the amount of your Canadian-source income. So if you earned $20,000 from Canadian sources and donated $5,000 to a Canadian charity, you can deduct the $5,000. If you had no Canadian-source income, the treaty doesn’t help.

The same principle works in reverse. A Canadian resident who donates to a US 501(c)(3) can claim the donation tax credit on their Canadian return, limited to their US-source income. The CRA treats the organization as if it were a registered Canadian charity, but only for that capped amount.

There’s one notable exception. For donations to certain organizations that the “competent authorities” of both countries have agreed to recognize (primarily colleges, universities, and hospitals near the border), the income-source limitation is relaxed. These “dual-qualified” organizations get more favorable treatment under the treaty.

For a deeper look at the treaty’s structure, see our guide to the Canada-US Tax Treaty.

What are dual-qualified charities?

Dual-qualified charities are organizations recognized as tax-exempt in both Canada and the US, which means donations to them can generate tax benefits in either country without the usual income-source limitations that apply under the treaty.

The most common examples are universities and hospitals that operate near the border or have a significant donor base in both countries. The University of Toronto, McGill University, and several large Canadian hospitals appear on the IRS’s list of recognized foreign organizations. Similarly, US institutions like the University of Michigan or the Mayo Clinic are recognized by the CRA as qualified donees for Canadian donors.

For these organizations, the treaty’s income-source cap is effectively relaxed. A US donor can claim a deduction for a gift to a qualifying Canadian university even without Canadian-source income, as long as the organization meets the treaty’s criteria. The practical advantage is significant: you get the tax benefit without having to calculate and prove foreign-source income.

The challenge is confirming whether a specific organization qualifies. The IRS maintains a Tax Exempt Organization Search tool, and some treaty-eligible foreign organizations appear there. For Canadian donors, the CRA’s list of qualified donees is the starting point, but treaty-eligible US organizations aren’t always listed explicitly. In practice, you may need to check the organization’s status with both tax authorities or review specific treaty protocols.

Why don’t cross-border donations just work?

Each country’s tax system only recognizes its own approved charities by default. The CRA won’t give you a donation credit for a gift to the American Red Cross, and the IRS won’t give you a deduction for a gift to the Canadian Red Cross, unless you can invoke the treaty.

This catches people off guard, especially dual citizens and cross-border workers who support organizations in both countries. You might write a check to your alma mater across the border, get a receipt, claim it on your return, and then receive a reassessment stripping the credit or deduction. The CRA is particularly strict about this. If the organization isn’t on their qualified donee list and you can’t demonstrate treaty eligibility, the credit is denied.

Documentation gaps compound the problem. A Canadian official donation receipt doesn’t contain all the information the IRS requires for a US filing. An IRS-compliant acknowledgment letter doesn’t satisfy CRA receipt requirements. If you’re filing in both countries (as many cross-border individuals do), you may need two different documents from the same charity for the same gift.

There’s also a timing issue. Canada and the US have different rules about when a donation is “made” for tax purposes. Credit card gifts, pledges, and gifts of property can create mismatches between the two countries’ recognition dates. Getting the year wrong means the benefit lands on the wrong return, or doesn’t land at all.

What receipts do you need for each country?

Canadian official donation receipts must include specific information prescribed by CRA regulations: the charity’s name and registration number, the donor’s name and address, the date and location of the gift, the eligible amount, a description of any advantage received, and the charity’s signature. Missing any required element can void the credit.

For cash donations, the receipt is usually straightforward. For gifts in kind (property donations), the receipt must also state the appraised fair market value and include a description of the property. The CRA’s requirements are laid out in Regulation 3501 of the Income Tax Regulations.

The IRS has its own set of rules. For cash donations of $250 or more, you need a contemporaneous written acknowledgment from the charity stating the amount, whether any goods or services were provided in return, and a good-faith estimate of their value. “Contemporaneous” means you must have it by the earlier of your filing date or the return’s due date (including extensions).

Non-cash donations over $500 require Form 8283, and donations of non-cash property over $5,000 generally require a qualified appraisal. The threshold drops for publicly traded securities, which don’t need an appraisal since the FMV is readily determinable from market data.

What happens when you donate appreciated property?

Donating property that has gone up in value (stocks, real estate, artwork) triggers different rules in each country. The tax treatment of the built-in gain is the key difference, and it can make or break the economics of a cross-border gift.

In Canada, donating capital property to a charity triggers a deemed disposition at fair market value under ITA 69(1)(b)(ii). You’re treated as if you sold the property at FMV and then donated the cash proceeds. The resulting capital gain is included in income (at the prevailing inclusion rate), but the donation credit offsets the extra tax. For publicly listed securities donated directly to a registered charity, Canada goes further: the capital gains inclusion rate drops to zero under ITA 38(a.1). This makes donating appreciated public company shares one of the most tax-efficient charitable giving strategies available in Canada.

Special categories of property get enhanced treatment. Ecological gifts (donations of ecologically sensitive land) and certified cultural property enjoy a zero inclusion rate on any resulting capital gain, and the 75% net income limit doesn’t apply to them.

In the US, donating appreciated capital gain property held for more than one year to a public charity gives you a deduction equal to the full fair market value, with no recognition of the built-in gain under IRC 170(e). The AGI limit is 30% instead of 60%, but there’s no capital gains tax on the transfer. For publicly traded securities, this creates a double benefit: you avoid capital gains tax and get a deduction at FMV.

Short-term property (held one year or less) and ordinary income property are limited to a deduction of your cost basis, not FMV. This distinction matters for founders holding stock with a low basis, where timing the holding period around the one-year mark can significantly change the tax outcome.

How do corporate donations differ?

Canadian and US corporations face different charitable giving frameworks, and the cross-border layer adds another set of constraints. The basic mechanics diverge at the structural level.

Canadian corporations can claim a deduction (not a credit) for charitable donations under ITA 110.1. The limit is 75% of net income, consistent with the individual rules. Unused donations carry forward five years. The deduction reduces taxable income, so the tax savings depend on the corporation’s effective tax rate. Combined federal and provincial rates typically range from about 12% to 26%, depending on the province and whether the small business deduction applies.

US corporations deduct charitable contributions under IRC 170(b)(2), with an annual limit of 10% of taxable income (computed before the charitable deduction and certain other adjustments). Excess contributions carry forward five years. C corporations that donate inventory for the care of the ill, needy, or infants may qualify for an enhanced deduction under IRC 170(e)(3).

Cross-border corporate donations face the same treaty limitations as individual donations. A Canadian corporation donating to a US 501(c)(3) can only deduct the gift to the extent of its US-source income. A US corporation donating to a Canadian registered charity faces the corresponding restriction. For multinational companies with operations in both countries, this is usually workable. For a purely domestic company making a one-off cross-border gift, the treaty may not help at all.

Pass-through entities (S corporations in the US, partnerships in both countries) pass the deduction or credit through to their owners, who then face the individual-level rules and limitations discussed above.

What about private foundations?

Private foundations operate under heavily regulated frameworks in both countries, and the rules differ enough to create real traps for cross-border philanthropy. Both regimes share the same basic concern (ensuring charitable dollars actually reach charitable purposes) but take different approaches to enforcement.

In Canada, private foundations must meet a “disbursement quota” under ITA 149.1: they’re required to spend a minimum percentage of their assets on charitable activities or gifts to qualified donees. As of 2023, the quota is 5% of assets not used directly in charitable activities. Failure to meet the quota can result in penalties or revocation of charitable status. Canadian private foundations can give to other registered charities but face restrictions on gifts to non-qualified donees, which generally includes foreign charities unless specifically approved.

US private foundations must distribute at least 5% of their net investment assets annually under IRC 4942. The penalty for failure is a 30% excise tax on the undistributed amount. US foundations can make grants to foreign organizations, but they must exercise “expenditure responsibility” under IRC 4945(h) (verifying the funds are used for charitable purposes) or confirm the foreign grantee is equivalent to a US public charity through an equivalency determination.

Cross-border grants between foundations introduce additional scrutiny. A Canadian private foundation granting to a US charity needs to confirm the recipient is a qualified donee (or rely on the treaty). A US private foundation granting to a Canadian charity must complete expenditure responsibility or an equivalency determination. Neither process is impossible, but both require advance planning and proper documentation. Skipping these steps can trigger excise taxes in the US or jeopardize charitable status in Canada.

How does donating to a US university work?

This is one of the most common cross-border donation scenarios: a Canadian resident (often an alumnus) wants to donate to a US college or university and claim the donation credit on their Canadian return.

If the university is a dual-qualified organization under the treaty, the donor can claim the credit without worrying about the income-source limitation. Many major US universities (Harvard, Stanford, MIT, and others) maintain treaty-eligible status. The donor claims the donation on their Canadian return as if the gift were made to a Canadian registered charity, using the same credit rates and carryforward rules.

If the university isn’t dual-qualified, the donor needs US-source income to claim the credit under Article XXI. This might come from US employment, US rental property, US investment income, or a US pension. The credit is capped at the Canadian tax attributable to that US-source income. If the donor has no US-source income, the donation provides no Canadian tax benefit at all.

In either case, the donor needs a receipt that meets CRA requirements. Most major US universities will issue a receipt suitable for Canadian tax filing if you ask, but smaller institutions may not be familiar with the requirements. It’s worth requesting the receipt in advance and specifying what information you need.

Some Canadian donors route their gifts through organizations like the US-Canada Foundation or similar intermediaries that hold registered charity status in both countries. This can simplify the documentation, though you should verify the intermediary’s status with both the CRA and IRS before relying on this approach.

What if a US resident donates to Canada?

A US resident donating to a Canadian registered charity faces the mirror image of the rules above. The treaty can unlock the deduction, but the income-source limitation applies unless the Canadian organization is dual-qualified.

If you’re a US resident with Canadian-source income (rental income from a Canadian property, Canadian pension income, or income from Canadian employment), you can deduct your donation to a Canadian registered charity on your US return under Article XXI, up to the amount of your Canadian-source income. The donation is treated as if it were made to a US 501(c)(3) for deduction purposes, subject to the same AGI limits and documentation requirements.

Without Canadian-source income, you need a dual-qualified charity. Canadian hospitals and universities near the border are the most common examples. If the organization qualifies, the income-source limitation falls away and you can deduct the gift like any domestic charitable contribution.

A common mistake: assuming that because you pay Canadian tax (say, through withholding on Canadian pension income), the charitable deduction automatically applies. The treaty requires Canadian-source income, not just Canadian tax liability. The two usually go together, but they’re not the same thing, and the distinction matters when you’re calculating the cap.

Also keep in mind that the donation must meet US documentation standards to support the deduction. A Canadian official donation receipt alone won’t satisfy the IRS. You’ll need a written acknowledgment that conforms to IRC 170(f)(8) requirements, and for non-cash gifts over $500, you’ll need Form 8283 as well.

How should dual citizens handle donations?

Dual citizens filing in both countries have the most complex planning landscape, but also the most opportunities. Every donation potentially generates benefits on two returns, and the key is structuring gifts to maximize the combined benefit.

The first step is identifying which charities are recognized in both countries. Donations to dual-qualified organizations (treaty-eligible universities, hospitals, and certain cross-border charities) are the simplest case. You claim the donation credit on your Canadian return and the itemized deduction on your US return for the same gift. There’s no income-source limitation to worry about.

For donations to charities recognized in only one country, the treaty’s income-source rule determines whether you can claim the benefit on the other country’s return. A dual citizen living in Canada with US-source investment income can donate to a US 501(c)(3) and claim the credit on their Canadian return up to the Canadian tax on that US-source income. On their US return, they claim the deduction normally since the US recognizes its own 501(c)(3) organizations without any treaty needed.

One pitfall dual citizens face: the foreign tax credit interaction. If you claim a donation credit in Canada that reduces your Canadian tax, you may have less Canadian tax available to offset against your US tax through the foreign tax credit. The donation saves you tax in one country but may increase your net tax in the other. The combined benefit is still positive in most cases, but it’s rarely as large as adding the two benefits together would suggest.

Timing matters too. If you bunch donations into one year for US itemized deduction purposes, make sure the Canadian 75% net income limit doesn’t create a carryforward that complicates things. Coordinating the two countries’ carryforward rules (both allow five years) requires planning, especially in years when income fluctuates.

Consider donating appreciated securities directly whenever possible. Both countries offer significant tax advantages for in-kind donations of publicly traded shares: zero capital gains inclusion in Canada, no gain recognition plus FMV deduction in the US. For a dual citizen holding appreciated stock, this is almost always better than selling and donating cash.

How can you plan cross-border gifts effectively?

Effective cross-border charitable giving comes down to three things: choosing the right charities, documenting properly, and coordinating the tax treatment across both returns. Here’s a practical framework.

Choose dual-qualified organizations when possible. If the charity you want to support is recognized in both countries, you avoid the income-source limitation entirely. Ask the organization about their treaty status before making a large gift. Major universities and hospitals typically know their status. Smaller charities may not.

Calculate your foreign-source income before committing. If you’re relying on the treaty’s income-source rule, know your number. Canadian-source income for a US resident includes Canadian employment income, rental income from Canadian property, Canadian pensions, and Canadian investment income. Get this figure right before you donate, not after.

Get the right receipts. Ask for documentation that covers both countries’ requirements if you’re filing in both. A CRA-compliant official donation receipt and an IRS-compliant written acknowledgment are different documents with different required elements. Large cross-border charities will often provide both if you ask.

Consider donating appreciated securities directly. Both countries offer significant tax advantages for in-kind donations of publicly traded securities: zero capital gains inclusion in Canada under ITA 38(a.1), no gain recognition plus FMV deduction in the US. If you hold appreciated stock and want to give, this is almost always better than selling and donating cash.

Watch the AGI and net income limits. The US 60% AGI limit for cash (30% for appreciated property) and Canada’s 75% net income limit can create carryforwards. If your donation is large relative to your income, model the multi-year impact before giving.

Don’t forget the foreign tax credit interaction. For anyone filing in both countries, the donation credit or deduction in one country may reduce the foreign tax credit available in the other. The net benefit is still positive, but the combined savings are rarely as simple as adding the two countries’ benefits together. Model the full cross-border impact, not just one return.

Coordinate with your cross-border tax advisor. The interaction between donation credits, deductions, and foreign tax credits is genuinely complex. A mistake doesn’t just reduce your benefit; it can trigger reassessments and penalties if the CRA or IRS determines you claimed a credit or deduction you weren’t entitled to.
