U.S. & Cross-Border Tax

The moment a Canadian business or individual touches the United States — making sales there, opening a location, holding property, or signing U.S. customers and contracts — the tax picture stops being purely Canadian. U.S. federal and state rules, cross-border reporting and the Canada–U.S. tax treaty all come into play, often at once. RN Canada helps Alberta and British Columbia businesses and individuals navigate that, coordinating the cross-border position and working with U.S.-licensed specialists where complex U.S. filings require them.

What's included

• Cross-border assessment. Working through whether your U.S. activity creates U.S. federal or state tax obligations, and what Canadian and cross-border reporting goes alongside them.
• Treaty coordination. Planning how the Canada–U.S. tax treaty applies to your situation — relief from double taxation, withholding and the conditions that have to be met to claim it.
• Cross-border structuring. Considering how a business or investment is structured on both sides of the border, so the arrangement is efficient and compliant rather than creating avoidable exposure.
• Reporting coordination. Bringing the Canadian return and the cross-border reporting into one coordinated picture, so nothing falls between the two systems.
• Specialist coordination. Engaging U.S.-licensed specialists for complex U.S. filings, with RN Canada coordinating the overall position so the two sides stay aligned.

How we work

Cross-border tax goes wrong most often when the two countries are handled separately and the pieces do not fit. We work the other way: starting from your facts, mapping the obligations that exist on each side, planning the treaty position, and keeping the Canadian and U.S. work coordinated. For complex U.S. filings, we bring in U.S.-licensed specialists whose licence and expertise are required, and we coordinate that work rather than hand you off to it — so you deal with one connected approach.

We keep this work qualitative and grounded in your specific situation. Cross-border thresholds, rates and rules change and turn on facts, so we identify the obligations that apply and plan around them rather than quoting figures that may not fit your case. The framework is the Canada–U.S. tax treaty and the reporting rules of each country; the analysis is yours.

Who it's for

This service fits Alberta and BC businesses selling into, or expanding into, the United States; companies with U.S. operations, property or subsidiaries; and individuals with U.S. citizenship, residency, property or income who also have Canadian obligations. It suits anyone whose tax position now straddles the border and who wants the two sides coordinated rather than managed in isolation, where gaps and double taxation tend to appear.

How RN Canada helps

We assess your cross-border position, plan the treaty and reporting approach, prepare and coordinate the work, and bring in U.S.-licensed specialists for the complex U.S. filings that require them — keeping the whole picture aligned. Because we also handle your Canadian corporate and personal tax, the U.S. and Canadian sides are planned together. For the Canadian side specifically, see corporate and personal tax.
