Frequently Asked Questions
Questions answered by our cross-border accountants in Toronto.
How do you avoid double taxation between the US and Canada?
It depends. Canadian residents pay tax on worldwide income, and the IRS may tax your US income too. The US-Canada Tax Treaty prevents double taxation through foreign tax credits. A cross-border tax advisor helps you structure things right.
How can I avoid double taxation on foreign income in Canada?
Claim foreign tax credits for US taxes paid, use treaty elections, and structure your entities correctly. Smart Canada US tax planning with a cross border accountant ensures you keep more of what you earn.
What is the double tax treaty between Canada and the US?
An agreement that determines which country taxes what income and at what rate. It provides lower withholding rates, foreign tax credits, and permanent establishment rules. Proper Canada US tax compliance means using the treaty to your advantage.
What does a cross-border accountant do?
A cross-border accountant handles Canada US tax compliance in both countries: Form 1120-F for Canadian companies earning in the US, Form 1120 for US corporations, and treaty elections on Form 8833. They also help with entity structure and permanent establishment risks.
What is the 183-day rule for Canadians in the US?
If you’re in the US for 183+ days in a year (or hit the three-year formula), you could be seen as a US tax resident. This changes how your income is taxed and which treaty benefits apply. We provide international tax advice in Toronto to help business owners navigate this.
What is a permanent establishment under the US-Canada Tax Treaty?
A fixed place like an office, warehouse, or employees who regularly close deals in the other country. If your Canadian company has one in the US, those profits can be taxed by the IRS (even with the treaty).
What are the US-Canada tax treaty withholding rates?
Dividends are 5% (if you own 10%+ voting stock) or 15%. Interest is usually 0%. Royalties are mostly 0%. You only get these rates by filing the right forms. Good Canada US tax planning stops you from overpaying.
Do Canadian citizens need to comply with FATCA?
FATCA targets US citizens and residents, not Canadians directly. But if your Canadian business has US accounts or shareholders, banks may report under FATCA. US subsidiaries may require Form 5471 or 8865. Proper US tax preparation in Canada helps you avoid penalties.
What is the 90% rule for non-residents in Canada?
This rule allows non-residents to claim extra credits and deductions if 90%+ of their worldwide income comes from Canada. For US owners running Canadian operations, it can lower your Canadian tax bill. Our non resident tax advisor in downtown Toronto uses this for effective Canada US tax compliance.
My Canadian company has US clients. Do I need to file anything with the IRS?
If you earn US-source income, you may need Form 1120-F. Whether you owe tax depends on the treaty and permanent establishment status. Even if no tax is due, filing keeps deduction options open. Talk to a cross border tax accountant in Toronto for US tax preparation in Canada.
How much does a cross-border tax advisor charge?
Our fees are $3000 to $5000/month per entity. It depends on your situation and needs. Book a free call with our Canada US tax CPA for more information.
