If you earn income in both Canada and the U.S., tax season can get complicated quickly.

‍

With the CRA’s April 30th deadline approaching, here’s what cross-border filers need to know.

‍

1. You May Have to File in Both Countries

‍

U.S. citizens and green card holders must file a federal return with the IRS, regardless of where they live.

‍

Canadians with U.S. income may also have to file depending on source and type of income.

‍

2. Don’t Rely on Online Tax Softwares Alone

‍

Automated software can’t handle cross-border credits, tax treaty interpretations, or FBAR filings. One small mistake can lead to big penalties or double taxation.

‍

3. Use the Canada–U.S. Tax Treaty‍

‍

The tax treaty helps determine which country gets taxing rights and provides ways to offset taxes paid to the other country. But it needs to be applied properly and documented.

‍

4. Work With a Cross-Border Specialist

‍

Filing in two systems isn’t just about compliance—it’s about strategy. A specialist can help you coordinate filings, reduce taxes, and stay ahead of both CRA and IRS changes.

‍

April 30th is the Canadian filing deadline. U.S. federal returns are due April 15th unless extended.

‍

Don’t wait, cross-border filings take longer.
