Form 1116 Foreign Tax Credit: How U.S. Taxpayers in Canada Can Claim Foreign Taxes

If you are a U.S. citizen or other U.S. taxpayer living in Canada, you may find yourself paying income tax to both Canada and the United States. This could raise an important question: If I already paid Canadian income tax, do I have to pay U.S. tax on the same income again? Not necessarily.

The U.S. Foreign Tax Credit can provide relief when qualifying foreign income taxes are imposed on income that is also subject to U.S. tax. For many taxpayers, the credit is calculated using Form 1116, Foreign Tax Credit (Individual, Estate, or Trust). The IRS explains that the foreign tax credit can generally be claimed for qualifying foreign income taxes paid or accrued to a foreign country when the applicable requirements are met.

For U.S. taxpayers living in Canada, this can make Form 1116 an important part of the cross-border tax return.

What is Form 1116?

Form 1116, Foreign Tax Credit, is a U.S. tax form used by individuals, estates, and trusts to calculate the foreign tax credit when the taxpayer has qualifying foreign taxes. The purpose of the credit is to reduce the effect of double taxation. For example, imagine a U.S. citizen living in Ontario who earns employment income from a Canadian employer.

The income may be taxable in Canada because the individual is a Canadian resident. At the same time, the U.S. generally taxes its citizens on worldwide income. Without some form of relief, the same income could potentially be subject to income tax in both countries. The foreign tax credit can help address this overlap.

Who can use Form 1116?

Form 1116 is generally used by an individual, estate, or trust that paid or accrued certain qualifying foreign taxes. However, not every foreign tax qualifies for a credit, and not every taxpayer who paid foreign tax needs to file Form 1116.

The IRS provides a limited exception for certain taxpayers with qualifying passive-category foreign income and relatively small amounts of foreign taxes. Under the current rules, an individual may be able to claim the credit without Form 1116 when all qualifying foreign-source gross income is passive-category income, the income and foreign taxes are reported on qualifying payee statements, and total creditable foreign taxes do not exceed $300 ($600 for married filing jointly).

For many U.S.-Canada cross-border taxpayers, however, Form 1116 is an important part of the foreign tax credit calculation.

What Canadian taxes can potentially qualify?

The foreign tax credit is not a credit for every type of tax paid to Canada. Generally, the IRS allows a credit for qualifying foreign income, war profits, and excess profits taxes, or certain taxes imposed in lieu of such taxes.

For a U.S. taxpayer living in Canada, Canadian income tax may potentially qualify. For example, a Canadian resident who pays Canadian income tax on employment income may potentially have qualifying foreign income taxes for purposes of the U.S. foreign tax credit. However, the analysis should be performed carefully.

The amount withheld or paid does not automatically equal the amount that is creditable for U.S. purposes. For example, if a taxpayer is entitled to a refund of foreign tax under Canadian law or an applicable treaty, the excess may not be creditable in the United States.

How does the foreign tax credit work?

The basic idea is relatively simple: Foreign income is subject to U.S. tax → qualifying foreign income tax is paid → foreign tax credit may reduce the U.S. tax attributable to foreign income. But the actual calculation is more complicated because the credit is subject to a foreign tax credit limitation.

The IRS explains that the credit generally cannot exceed the U.S. tax attributable to the taxpayer's foreign-source taxable income. The limitation is calculated using foreign-source taxable income relative to total taxable income. This means that you cannot necessarily claim an unlimited credit simply because you paid a large amount of Canadian tax.

Suppose a U.S. taxpayer living in Canada has:

• U.S. tax before foreign tax credit: $8,000

• Qualifying Canadian income taxes: $10,000

It would be incorrect to assume that the taxpayer automatically receives a $10,000 U.S. tax credit and gets a $2,000 refund.

The foreign tax credit is subject to limitations. The taxpayer's actual allowable credit depends on the foreign-source income and the applicable foreign tax credit limitation.

Why isn't the credit always equal to the Canadian tax paid?

This is one of the most important concepts to understand. The foreign tax credit is designed to prevent double taxation, but it is not generally an unrestricted dollar-for-dollar reimbursement of foreign taxes.

The IRS limits the credit to the U.S. tax attributable to foreign-source taxable income. Consequently, two taxpayers who each pay $10,000 of Canadian income tax could potentially have different U.S. foreign tax credits.

The calculation depends on their income, its source, deductions, income category, and other applicable rules.

What are the income categories on Form 1116?

Form 1116 separates foreign income into different separate categories, because different types of foreign income can be subject to different foreign tax credit limitations. Common categories include:

• Passive category income

• General category income

• Certain other specialized categories of income

For many individuals living in Canada, employment or business income may fall into a different category from interest and dividend income. This matters because foreign taxes generally cannot simply be pooled together and used against any U.S. tax liability the taxpayer chooses. The IRS instructions require separate foreign tax credit calculations for the applicable categories of income.

What if I have Canadian employment income?

Canadian employment income is one of the most common situations for U.S. citizens living in Canada.

Suppose David is a U.S. citizen living in Ontario and working for a Canadian employer. He earns CAD $100,000 of employment income and pays Canadian income tax. David generally needs to report the income on his U.S. tax return because U.S. citizens are generally subject to U.S. tax on worldwide income. He may then be able to claim a foreign tax credit for qualifying Canadian income taxes, subject to the applicable rules and limitations.

The calculation may involve determining the U.S.-dollar amount of both the income and the foreign taxes and allocating income and taxes to the appropriate foreign tax credit category.

What if I paid Canadian tax through payroll withholding?

Canadian employees often have income tax withheld from their paycheques throughout the year. These amounts can ultimately become part of the Canadian income tax liability. However, taxpayers should distinguish between income tax and other amounts withheld from Canadian employment income. For example, Canadian payroll deductions can include:

• Federal income tax

• Provincial income tax

• CPP contributions

• EI premiums

These amounts do not all receive the same treatment for U.S. foreign tax credit purposes.

The foreign tax credit generally applies to qualifying foreign income taxes, not simply every amount deducted from a Canadian paycheque. This is particularly important when preparing a U.S. return for someone who has Canadian employment income.

What if I paid U.S. tax and Canadian tax?

This is common for cross-border taxpayers. For example, a U.S. citizen living in Canada could have:

• Canadian employment income

• U.S. investment income

• Canadian investment income

• U.S. rental income

• Canadian rental income

Different items of income can have different sources and different tax treatment in each country. The foreign tax credit analysis therefore needs to consider which foreign tax relates to which foreign-source income. It is not always appropriate to take the total Canadian tax paid and simply apply it against the taxpayer's entire U.S. tax liability.

What about Canadian dividends and investment income?

Canadian interest and dividends can create additional foreign tax credit considerations. The U.S. tax treatment of investment income may differ from the Canadian treatment. For example, Canadian dividends may be subject to Canadian tax while also being subject to U.S. tax for a U.S. citizen living in Canada.

Foreign taxes related to investment income may potentially qualify for the foreign tax credit, subject to the applicable rules. Because passive income generally falls into the passive category for Form 1116 purposes, it is important to keep investment income and related foreign taxes properly identified.

What about Canadian capital gains?

Capital gains can be more complicated. Canada and the United States do not always calculate taxable capital gains exactly the same way. A taxpayer may therefore have:

• One amount of taxable gain for Canadian purposes

• A different amount of taxable gain for U.S. purposes

• Canadian tax attributable to the gain

• U.S. tax attributable to the gain

The foreign tax credit calculation must take these differences into account. The amount of Canadian tax paid does not automatically become an equal U.S. foreign tax credit.

What about Form 2555?

Form 1116 is often confused with Form 2555, Foreign Earned Income. They are different tax provisions. Form 1116 is used to calculate a foreign tax credit for qualifying foreign taxes.

Form 2555 is used to claim the Foreign Earned Income Exclusion when the taxpayer meets the applicable requirements. The foreign tax credit generally reduces U.S. tax, while the Foreign Earned Income Exclusion removes qualifying foreign earned income from U.S. taxable income. These rules also interact.

The IRS states that if you elect to exclude foreign earned income or foreign housing costs, you cannot claim a foreign tax credit for taxes on the income that is excluded. Therefore, taxpayers should not assume that using both forms automatically maximizes their tax savings.

Form 1116 vs. Form 2555

The better approach depends on the taxpayer's circumstances.

Can unused foreign tax credits be carried over?

Yes, in some circumstances. A taxpayer may have foreign taxes available for credit but be unable to use the entire amount in the current year because of the foreign tax credit limitation.

The IRS states that unused foreign taxes may generally be carried back to the previous tax year and forward for up to 10 tax years, subject to the applicable rules. This means that a taxpayer should not necessarily assume that foreign taxes that cannot be used this year are permanently lost.

The carry back and carryover rules can be particularly important for taxpayers whose foreign income and U.S. tax liability fluctuate from year to year.

What exchange rate should be used?

U.S. tax reporting generally requires amounts to be converted into U.S. dollars. This includes foreign income and foreign taxes.

The IRS instructions for Form 1116 provide specific currency-conversion rules. For foreign taxes paid, the conversion generally uses the exchange rate in effect on the date the foreign tax was paid or withheld. Different rules can apply when foreign taxes are reported on an accrual basis. This is important for Canadian taxpayers because Canadian tax records are generally maintained in Canadian dollars.

A taxpayer should therefore maintain documentation showing how Canadian-dollar amounts were converted into U.S. dollars for the U.S. return.

What happens if Canadian tax is later refunded?

Suppose a taxpayer claims a U.S. foreign tax credit based on Canadian taxes paid and later receives a refund of some of those Canadian taxes. The foreign tax credit may need to be adjusted.

The IRS instructions state that when foreign taxes for which a credit was claimed are later refunded, the taxpayer generally must account for the foreign tax redetermination and may need to file an amended U.S. return. This is another reason why the foreign tax credit should be based on the taxpayer's actual foreign tax liability rather than simply the amount temporarily withheld.

What if I am a Canadian resident who paid U.S. tax?

This is where an important distinction must be made. Form 1116 is a U.S. tax form.

If you are a Canadian resident and are claiming a Canadian foreign tax credit for U.S. income taxes, you generally look to the Canadian foreign tax credit rules rather than using Form 1116.

For Canadian residents, the CRA explains that the federal foreign tax credit is generally calculated using Form T2209, Federal Foreign Tax Credits, when qualifying foreign income taxes have been paid on income reported on the Canadian return. Therefore:

·       U.S. tax return → potentially Form 1116

·       Canadian tax return → potentially T2209

The direction of the tax credit matters. This distinction is particularly important for U.S.-Canada cross-border taxpayers who file returns in both countries.

U.S.-Canada example

Let's consider Sarah. Sarah is a U.S. citizen who lives in Ontario and works for a Canadian company. During the year:

• She earns Canadian employment income.

• She pays Canadian income tax.

• She files a Canadian T1 return.

• She is also required to file a U.S. Form 1040.

Sarah reports her Canadian employment income on her U.S. return. Because the same income may be subject to tax in both countries, she examines whether the Canadian income taxes she paid qualify for the U.S. foreign tax credit. If eligible, she may use Form 1116 to calculate the credit. The amount of the credit is then subject to the applicable foreign tax credit limitation. Sarah's result cannot be determined simply by comparing the Canadian tax paid with the U.S. tax shown on her return.

The foreign-source income and the applicable U.S. tax attributable to that income must be considered.

Common mistakes with Form 1116

Mistake 1: Treating all Canadian taxes as creditable

Not every Canadian tax or payroll deduction is automatically a qualifying foreign income tax.

Mistake 2: Assuming the credit equals Canadian tax paid

The foreign tax credit is subject to a limitation.

Mistake 3: Combining all foreign income

Different categories of foreign income can be subject to separate foreign tax credit limitations.

Mistake 4: Ignoring currency conversion

Canadian-dollar income and taxes generally need to be translated into U.S. dollars using appropriate exchange-rate rules.

Mistake 5: Claiming a credit for taxes on excluded income

If foreign earned income is excluded under Form 2555, the related foreign taxes generally cannot also be claimed as a foreign tax credit for that excluded income.

Mistake 6: Confusing Form 1116 with Canada's foreign tax credit

Form 1116 is for the U.S. tax return. Canadian residents claiming a Canadian foreign tax credit generally use the Canadian rules, including Form T2209 for the federal calculation where applicable.

The bottom line

For U.S. taxpayers living in Canada, the Form 1116 foreign tax credit can be an important mechanism for reducing double taxation when qualifying Canadian income taxes are also subject to U.S. tax. However, the credit is not simply a dollar-for-dollar refund of every Canadian tax paid. The taxpayer must determine:

• Which foreign taxes qualify

• Which income those taxes relate to

• The appropriate foreign income category

• The applicable foreign tax credit limitation

• The appropriate currency conversion

• Whether unused credits can be carried to another year

• Whether Form 2555 or other provisions affect the calculation

And remember the direction of the credit: U.S. taxpayer claiming a credit for qualifying Canadian income taxes on the U.S. return → Form 1116 may apply. Canadian resident claiming a credit for qualifying U.S. income taxes on the Canadian return → Canadian foreign tax credit rules, including T2209 where applicable, may apply.

For U.S.-Canada cross-border taxpayers, getting the foreign tax credit calculation right can make a significant difference in the overall tax result.
