Do US Citizens in Canada Have to File US Taxes?

In many cases, yes. Living in Canada does not automatically end a US citizen's federal tax filing obligations. The United States generally taxes US citizens on worldwide income, even when they live abroad.

That does not necessarily mean paying income tax twice. Depending on the facts, mechanisms such as foreign tax credits, exclusions, and provisions of the US–Canada tax treaty may reduce or coordinate overlapping taxation.

The important distinction is that having a US filing obligation is not the same thing as owing US tax.

This guide explains the main issues US citizens living in Canada should understand and when a cross-border tax review may make sense.

Do US Citizens Living in Canada Have to File a US Tax Return?

US citizens living abroad are generally subject to the same basic federal income tax filing rules as US citizens living in the United States.

Whether you are required to file a federal income tax return in a particular year depends on factors such as your worldwide income, filing status, age, and other circumstances.

Moving to Canada, becoming a Canadian tax resident, or earning all of your income in Canada does not by itself eliminate your US filing obligations.

For many Americans living in Canada, the practical result is that they may have reporting obligations in both countries even when their final US tax liability is reduced by credits, exclusions, or treaty rules.

If you need help determining what applies to your specific situation, see our US tax filing guidance for US citizens living in Canada.

Will You Pay Tax in Both the US and Canada?

Living in Canada can create tax obligations in both countries, but that does not automatically mean the same income will be fully taxed twice.

The result depends on factors such as tax residency, the source and type of income, treaty provisions, and which country has the primary right to tax a particular item.

Canadian Tax Residency

Canada generally taxes residents on worldwide income. Whether and when someone becomes a Canadian tax resident is fact-specific and can depend on residential ties and other circumstances.

This means a US citizen living in Canada may be subject to worldwide-income reporting rules in both countries at the same time.

Foreign Tax Credits

Foreign tax credits can help coordinate tax paid to one country against tax that may otherwise be due to the other country.

For example, a US citizen who pays Canadian income tax on Canadian-source income may, depending on the circumstances, be able to claim a US foreign tax credit for qualifying Canadian taxes paid.

The calculation is not always one-to-one. Different rules can apply depending on the type and source of income, so the presence of a foreign tax credit does not mean every cross-border situation produces a zero US balance.

The US–Canada Tax Treaty

The United States and Canada have an income tax treaty that contains rules intended to coordinate taxation between the two countries.

The treaty can affect items such as residency, pensions, investment income, employment income, and other cross-border situations.

Treaty treatment depends heavily on the facts. It should not be assumed that every type of income will receive the same result.

What US Forms May Apply to Americans Living in Canada?

A standard US income tax return may not be the only filing requirement for a US citizen living in Canada.

Depending on the person's circumstances, additional international information-reporting forms may apply.

Form 1040

Form 1040 is the individual federal income tax return used by US taxpayers to report income from worldwide sources when a filing requirement applies.

Income earned in Canada is not automatically excluded simply because it was earned outside the United States.

FBAR

The Report of Foreign Bank and Financial Accounts, commonly known as the FBAR, is a separate reporting requirement administered through the US Treasury's Financial Crimes Enforcement Network.

A US person generally has an FBAR filing requirement when the aggregate value of reportable foreign financial accounts exceeds US $10,000 at any time during the calendar year.

This threshold applies to the combined value of relevant foreign accounts, not $10,000 per account.

Canadian bank and investment accounts can therefore create an FBAR filing requirement even when the accounts do not generate significant taxable income.

FATCA and Form 8938

Form 8938 is another foreign financial asset reporting requirement that can apply when specified foreign financial assets exceed the applicable thresholds.

The thresholds depend on factors including filing status and whether the taxpayer is considered to be living abroad.

FBAR and Form 8938 are different reporting regimes. Filing one does not automatically eliminate the need to file the other.

Other International Reporting

Depending on the assets and entities involved, other US international information returns may also apply.

Examples can include reporting related to foreign corporations, foreign trusts, certain gifts, and other foreign financial interests.

This is one reason cross-border tax situations can become significantly more complex than a standard domestic US tax return.

What About Canadian Bank and Investment Accounts?

Canadian financial accounts can have different reporting and tax consequences in the United States.

Examples may include:

Canadian checking and savings accounts
brokerage and investment accounts
registered savings or retirement accounts
joint financial accounts
accounts over which the US person has signature authority

The fact that an account is tax-preferred or registered in Canada does not necessarily mean the United States treats it the same way.

Before making investment or retirement decisions, it is often useful to understand how both countries may view the account.

What If You Have Not Filed US Taxes for Several Years?

Some US citizens move to Canada without realizing that US filing obligations may continue.

Others may have filed US tax returns but later discover that foreign bank accounts or other international forms were not reported correctly.

If that applies to you, the right response depends on your individual circumstances.

The IRS has streamlined filing compliance procedures that may be available to certain taxpayers whose failures were non-willful. Eligibility depends on specific requirements and should not be assumed automatically.

Before filing several years of late returns or amended returns without a plan, consider having the situation reviewed so that the appropriate filing approach can be identified.

Have your filing history reviewed before taking corrective action.

Common Mistakes US Citizens in Canada Make

Common misunderstandings include:

assuming that becoming a Canadian resident automatically ends US tax filing obligations
assuming that filing a US return always means paying US income tax
forgetting that Canadian bank and investment accounts may create separate reporting requirements
treating FBAR and FATCA as if they were the same filing
assuming Canadian tax-preferred accounts automatically receive identical US tax treatment
waiting until an IRS notice arrives before reviewing missed filings
using tax advice designed only for Canadian taxpayers without considering US consequences

Many cross-border problems are easier to manage when they are identified before a transaction, move, investment decision, or filing deadline.

When Should You Get Cross-Border Tax Help?

A professional cross-border review may be particularly useful if you:

recently moved from the United States to Canada
are planning to move to Canada
have not filed US tax returns for one or more years
have Canadian bank or investment accounts
own Canadian property
own or operate a business in either country
receive income from both the United States and Canada
have retirement or investment accounts in both countries
are unsure whether previous US filings were complete

US–Canada tax issues often involve several rules at the same time. The objective is not simply to file more forms, but to understand which rules actually apply to your situation.

Frequently Asked Questions

Do US citizens living in Canada have to file US taxes every year?

US citizens living abroad remain subject to US federal filing rules. Whether a return is required in a particular year depends on factors such as worldwide income, filing status, age, and other circumstances.

Do I pay taxes twice if I live in Canada and am a US citizen?

Not necessarily. Foreign tax credits, treaty provisions, and other rules can help coordinate taxation between the two countries. The result depends on the type and source of income and the taxpayer's circumstances.

Do Canadian bank accounts need to be reported to the US?

They may. For example, an FBAR may be required when the aggregate value of reportable foreign financial accounts exceeds US $10,000 at any time during the calendar year. Other reporting requirements may also apply.

What is the difference between FBAR and FATCA?

FBAR and FATCA are separate reporting regimes with different rules and thresholds. A taxpayer may be required to file one, both, or neither depending on the facts.

What happens if I have not filed US taxes while living in Canada?

The appropriate solution depends on the circumstances and whether prior non-compliance was willful or non-willful. Certain taxpayers may qualify for IRS streamlined filing procedures, but eligibility should be reviewed before taking action.
