Treaty-first thinking.
We consider the Canada–U.S. tax treaty alongside each country's rules, so filing decisions account for both systems.
One focus. Both sides of the border.
Two countries.
One coordinated approach.
Canada USA Tax brings more than 25 years of hands-on tax practice to people and businesses with obligations in Canada and the United States.
A return filed correctly in one country can still leave obligations in the other. We look at the whole picture: your residency, income, accounts, and filing history on both sides of the border.

Clarity at every step.
Every engagement begins with understanding where your obligations sit — and what needs to be filed in each country.
Answers you can follow.
You'll understand why a form is being filed and how it fits your situation, including disclosure requirements that may not involve tax owed.
Support beyond April.
A move, a new account, or a job offer can change your tax position. We help you plan throughout the year.
