Common questions.

Where do we meet?

Virtually, or in person at our office about 15 minutes from Square One.

My e-commerce store sells into the US. Do I owe US tax?

Possibly — US state sales tax has economic nexus thresholds (commonly US$100,000 in sales or 200 transactions per state), and income tax exposure depends on how you operate. We review your footprint and tell you plainly what applies.

Can you work with my existing Canadian accountant?

Yes — we can handle just the US side and coordinate with them, or take on both sides as one engagement.
