Focused tax services, done properly
We keep our practice deliberately narrow: tax and tax advisory. Every engagement is handled by a CPA who works in this area every day.
Tax preparation & compliance
Canadian personal (T1) and corporate (T2) returns, plus US individual returns for clients with US filing obligations.
Learn more →Canada–US cross-border tax
Dual filers, US citizens in Canada, and Canadians with US income or assets: FBAR/FATCA, departure/arrival tax, ITIN, treaty positions.

Planning for cross-border moves, structuring, and specific tax questions, grounded in current Canadian and US tax law.
Learn more →Cross-border tax is where we spend our time
Moving between Canada and the United States creates overlapping filing obligations in both countries. We help individuals and businesses meet those obligations correctly and plan ahead for the tax consequences.
