Business and Corporate Tax
Cross-border structure and compliance for companies expanding between Canada and the United States.
Entity Selection and Expansion Planning
The preferred structure depends on ownership, activities, financing, profit expectations, treaty access, state or provincial exposure, repatriation plans, and exit strategy. We compare alternatives before formation or restructuring.
- Canadian corporation entering the United States
- US corporation establishing Canadian operations
- Subsidiary, branch, partnership, or direct-operation comparisons
- LLC classification and Canadian hybrid-entity concerns
- Permanent establishment and income-sourcing analysis
- Cross-border financing and payment flows
E-Commerce and Amazon Sellers
Inventory, employees, contractors, sales volume, marketplace activity, and other contacts might create state registration, sales tax, income tax, franchise tax, or gross-receipts obligations.

- Sales tax registration and filing coordination

Foreign ownership and related-party transactions often create special US reporting obligations. A foreign-owned disregarded entity might need a pro forma Form 1120 with Form 5472 even when it has little or no operating activity.
Cross-Border Payments

- Canadian Part XIII and Regulation 105 considerations
