If you are a U.S. citizen, you are generally subject to U.S. federal income tax filing requirements even if you live permanently in Canada. U.S. citizens are generally required to report their worldwide income on their U.S. tax return.
Canada, however, generally taxes individuals based on tax residency rather than citizenship. If you are considered a Canadian tax resident, you generally report your worldwide income on your Canadian tax return.
As a Canadian-American dual citizen living in Canada, you may therefore need to file:
While the same income may need to be reported in both countries, this does not necessarily mean that you will pay tax twice.
Canada and the United States have a comprehensive income tax treaty designed, among other things, to coordinate taxation between the two countries and reduce double taxation.
Depending on your circumstances, you may be able to use:
For many U.S. citizens living in Canada, foreign tax credits play an important role because Canadian income tax paid can often be credited against U.S. tax on the same income.
The Foreign Earned Income Exclusion is not always the most advantageous option. In particular, U.S. tax cannot generally be offset with a foreign tax credit for foreign taxes attributable to income that has been excluded using Form 2555.
In addition to filing an income tax return, U.S. citizens living in Canada may have separate foreign financial account and asset reporting obligations.
You generally must file an FBAR (FinCEN Form 114) if the aggregate maximum value of your foreign financial accounts exceeds US$10,000 at any time during the calendar year.
This is an aggregate threshold. For example, several Canadian accounts with balances below US$10,000 individually can still create an FBAR filing requirement if their combined value exceeds the threshold.
The FBAR is filed separately from your U.S. federal income tax return.
You may also need to file Form 8938, Statement of Specified Foreign Financial Assets, under FATCA.
Unlike the FBAR, Form 8938 has different reporting thresholds depending on factors such as:
For U.S. taxpayers who qualify as living abroad, the thresholds are substantially higher than the standard thresholds for taxpayers living in the United States.
FBAR and Form 8938 are separate reporting requirements, and some taxpayers may be required to file both.
Canadian registered accounts can receive very different treatment under Canadian and U.S. tax law.
RRSPs and RRIFs receive special treatment under the Canada-U.S. tax framework. Eligible U.S. taxpayers generally receive U.S. tax deferral on income accumulating inside qualifying Canadian retirement plans, and special IRS guidance eliminates certain information-reporting requirements that previously applied to these accounts.
However, RRSPs and RRIFs may still need to be considered for other reporting requirements, including FBAR and potentially Form 8938.
A Tax-Free Savings Account (TFSA) is tax-free in Canada, but it does not receive the same general U.S. tax treatment as an RRSP.
Investment income and capital gains earned inside a TFSA may therefore be taxable in the United States even though they are tax-free in Canada.
The investments held inside the TFSA may also create additional U.S. reporting requirements depending on what the account owns.
This difference is particularly important for Canadian-American dual citizens who assume that all Canadian registered accounts receive similar treatment in both countries.
Canadian mutual funds and certain Canadian ETFs can create particularly complex U.S. tax consequences.
For U.S. tax purposes, many non-U.S. investment funds may be classified as Passive Foreign Investment Companies (PFICs). Ownership of a PFIC can trigger Form 8621 reporting and special U.S. tax rules.
PFIC rules can result in significantly more complicated reporting and, in some circumstances, unfavorable U.S. taxation. Dual citizens should therefore consider the U.S. tax implications before purchasing Canadian mutual funds or similar investments.
Owning or controlling shares of a Canadian corporation may also create additional U.S. reporting obligations.
Certain U.S. citizens who are officers, directors, or shareholders of foreign corporations are required to file Form 5471, Information Return of U.S. Persons With Respect to Certain Foreign Corporations.
Whether Form 5471 is required depends on factors such as the percentage owned, changes in ownership, and the type of foreign corporation.
Additional U.S. tax rules may also apply to certain foreign corporations owned by U.S. shareholders.
Cross-border tax compliance involves more than simply determining whether additional tax is owed.
Many U.S. international forms are information-reporting forms, meaning a filing obligation can exist even when there is little or no U.S. income tax payable.
Failure to file required international information returns can result in significant penalties. This makes it particularly important for Canadian-American dual citizens to identify their filing obligations before assuming that no U.S. tax payable means no U.S. filing is necessary.
Being a Canadian-American dual citizen creates additional tax and reporting responsibilities, but proper planning can often prevent double taxation and unnecessary complications.
The key is understanding how the two tax systems interact, taking advantage of available foreign tax credits and treaty provisions, and identifying additional reporting requirements for Canadian accounts, investments, corporations, and registered plans.
