U.S. Taxes in Canada: A Guide for Expats and Dual Citizens

If you’re a U.S. citizen or dual citizen living in Canada, understanding your tax obligations on both sides of the border is essential. The U.S. tax system is unique in that it taxes citizens based on worldwide income, no matter where they live. This can create complications for Americans residing in Canada, leading to confusion and concerns about double taxation. 

To help you navigate these challenges, this guide covers the key points you need to know about filing U.S. taxes while living in Canada, along with helpful government resources to ensure you remain compliant. 

 Do You Need to File U.S. Taxes While Living in Canada? 

The short answer is yes. As a U.S. citizen or Green Card holder, you must file a U.S. tax return every year, regardless of your country of residence. This requirement applies even if all your income is earned in Canada and you pay Canadian taxes. 

According to the IRS, “if you are a U.S. citizen or a resident alien living outside the United States, your worldwide income is subject to U.S. income tax, regardless of where you live.”

Additionally, if you meet Canada’s tax residency rules, you are also required to report your worldwide income to the Canada Revenue Agency (CRA). Typically, if you are in Canada for 183 days or more in a calendar year, or you have significant residential ties (like a home or family), you are considered a Canadian tax resident.

How to Avoid Double Taxation 

Filing taxes in two countries doesn’t necessarily mean you’ll be taxed twice on the same income. Thanks to the Canada-U.S. Tax Treaty, there are provisions that prevent double taxation: 

1. Foreign Tax Credit (FTC) 

You can claim a credit on your U.S. tax return for income taxes paid to Canada, reducing your U.S. tax liability.
➡️ IRS – Foreign Tax Credit (Form 1116) 

2. Foreign Earned Income Exclusion (FEIE) 

You may be able to exclude up to $126,500 USD (for 2024) of foreign-earned income from your U.S. taxes if you meet certain residency requirements.
➡️ IRS – Foreign Earned Income Exclusion (Form 2555) 

Using these tools properly often means you won’t owe additional U.S. taxes, but filing is still mandatory, even if your final U.S. tax bill is $0. 

 

What Tax Forms Do U.S. Expats in Canada Need? 

When filing U.S. taxes from Canada, these are some of the key forms to know: 

  • Form 1040 – U.S. Individual Income Tax Return (every U.S. citizen must file this). 
  • Form 2555 – To claim the Foreign Earned Income Exclusion (FEIE). 
  • Form 1116 – To claim the Foreign Tax Credit (FTC). 
  • Form 8938 – To report foreign financial assets if they exceed certain thresholds. 

 

Common Mistakes to Avoid 

Filing U.S. taxes from Canada can be tricky, and expats often make these mistakes: 

  • Not filing at all – Many assume they don’t need to file if they owe no U.S. tax. This is incorrect. 
  • Incorrect currency conversion – All amounts must be reported in USD, using the exchange rate for the year. 
  • FBAR non-compliance – Failing to report foreign bank accounts can lead to heavy fines, even if the accounts hold modest sums. 
  • Overlooking Tax Treaty Benefits – Not using the Foreign Tax Credit or Foreign Earned Income Exclusion could lead to unnecessary taxes. 

 

Real Estate and Capital Gains for U.S. Expats in Canada 

If you own property in Canada and sell it, you may face capital gains taxes in both Canada and the U.S.. However, the Primary Residence Exclusion in the U.S. may help reduce your U.S. capital gains tax if the home was your primary residence for at least 2 out of the last 5 years. 

It’s important to accurately report the fair market value of the property in U.S. dollars when filing your U.S. tax return. 

 

Reporting Canadian Bank Accounts and Investments 

As a U.S. citizen in Canada, you must report your Canadian financial accounts if the combined value exceeds $10,000 USD at any time during the year. This includes: 

  • Bank accounts 
  • Investment accounts 
  • Certain pension plans 

This is done through FBAR reporting (FinCEN Form 114), separate from your regular tax return. 

Additionally, Form 8938 may be required if your total foreign assets exceed $200,000 USD (for single filers living abroad). 

 

The Canada-U.S. Tax Treaty 

The Canada-U.S. Tax Treaty plays a crucial role in simplifying tax obligations and preventing double taxation. It clarifies residency rules, defines taxing rights on different income types, and provides reduced tax rates or exemptions in certain cases. 

Reading the treaty itself can be helpful if you’re dealing with complex cross-border financial matters. 

Filing Deadlines for U.S. Expats in Canada 

  • U.S. Tax Deadline: April 15 (Automatic extension to June 15 for expats) 
  • Canadian Tax Deadline: April 30 (June 15 for self-employed individuals) 

It’s recommended to start early to ensure you have all documents ready and avoid last-minute issues. 

 

Best Practices for U.S. Expats in Canada 

✅ Keep Records – Maintain detailed records of your income, tax payments, and currency conversions.
✅ Stay Updated – Tax laws change; check IRS and CRA websites regularly.
✅ Consult a Cross-Border Tax Professional – Tax filing can get complex when dealing with two countries.
