Both sides of the border, coordinated
Handled here
Running a business or holding income across the Canada-US border adds a layer most local accountants don't handle well. Tax treaties, foreign reporting forms, and dual filing deadlines all interact.
We work with Mississauga businesses and individuals who have cross-border operations, US-source income, or an entity set up outside Canada, keeping both sides of the filing compliant.
What's Included
Tap each part of the engagement to see what it covers.
Tax Treaty Application
We apply the Canada-US treaty and other relevant agreements so income isn't taxed twice on the same dollar.
Why Work With This Team
We handle both sides
Cross-border filing means understanding two systems at once, not just the Canadian half.
Treaty-based planning
We apply tax treaties actively, not as an afterthought once a double-taxation problem has already appeared.
Focused on the numbers, not a sales pitch
The goal is a compliant filing on both sides of the border, not an upsell into services you don't need.

Frequently Asked Questions
Do I need to report foreign property to CRA?
Yes, if the total cost of specified foreign property exceeds $100,000 CAD, you file form T1135.
Can I be taxed on the same income in two countries?
Tax treaties are designed to prevent that, but only if applied correctly. Filings are structured to use those treaty provisions properly.
What documents do you need to start a cross-border filing?
T-slips or their US equivalent, details of foreign accounts or property, and any existing tax filings from the other country involved.
