U.S. Tax Accounting

For American citizens living in Canada, U.S. tax accounting means navigating two tax systems at once — the IRS in the United States and the CRA in Canada. Filing two sets of returns with different rules, deadlines, and compliance requirements is complex, and the penalties for getting it wrong can be severe.

At Filing Taxes, our experienced Toronto-based accountants handle the full process of U.S. tax accounting in Canada — from preparation and filing to planning and IRS correspondence — so you can live and work across borders with total confidence.

At Filing Taxes, we integrate both your personal and corporate tax interests into a single, clear strategy that cuts through the complexity and gives you one less thing to worry about.

Whether you are a high-net-worth individual, a business owner, or an expat managing international obligations, our accountants in Toronto provide the forward-thinking advice and hands-on support you need to stay fully compliant with both the IRS and CRA.

Back-Filing US Taxes — IRS Expat Tax Amnesty Program

If you have not filed US tax returns for previous years, the IRS Expat Tax Amnesty Program may allow you to catch up without facing penalties — provided your past non-filing was non-wilful. To qualify, you generally need to file the last 3 years of federal tax returns, provide 6 years of FBAR (Foreign Bank Account Reports), and pay any tax owed.

Our Toronto accountants guide you through the entire back-filing process efficiently and accurately, fulfilling all US tax filing requirements, maintaining compliance, and reducing double taxation wherever possible. This service pairs seamlessly with our non-resident tax services for clients with broader Canadian obligations as well.

How to File a US Tax Return from Canada

Filing a US tax return from Canada requires either a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN). If you do not have either, our team can assist you in applying for an ITIN before filing begins.

You will also need the correct US tax return forms — which vary depending on your residency status, income type, and whether you are filing as an individual or corporation. Once prepared, your return must be submitted to the IRS within the required timeframe to avoid late penalties. Our personal tax accountants and corporate tax specialists manage every step of this process on your behalf.

US Tax Return Forms — Which One Do You Need?

Choosing the correct US tax return form is critical to filing accurately and avoiding IRS penalties. Our Toronto accountants verify exactly which forms apply to your situation before preparing anything.

The most common forms we work with include:

Form 1040 — US Individual Income Tax Return The standard federal return for US citizens, green card holders, and US residents including those who pass the substantial presence test. Used to report gross income, claim deductions, and apply tax credits.

Filing a US Tax Return as a Non-Resident

As a non-resident, you must file a US tax return if you are engaged — or considered to be engaged — in trade or business in the United States during the tax year. You must also file if you have US-sourced income on which tax was not fully withheld at the source, or if you want to claim a refund of excess withholding or deductions such as rental property expenses.

While Canadian non-residents are generally exempt from US tax obligations under certain conditions, specific income thresholds and treaty provisions can change that. Our accountants carefully assess your full situation to determine your US filing status and prepare your return with maximum accuracy and minimum liability.
