cross-border and Canadian tax, handled with professional care
A CPA-led advisory firm focused on US–Canada cross-border tax, personal and corporate tax preparation, and tax advisory for individuals and businesses with ties on both sides of the border.
Led by Elena Serebryany, CPA, CA (Ontario) & US CPA (Florida) — IRS Certifying Acceptance Agent.
Focused tax services, done properly
We keep our practice deliberately narrow — tax and tax advisory — so 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 →US–Canada cross-border tax
Dual filers, US citizens in Canada, and Canadians with US income or assets — FBAR/FATCA, departure/arrival tax, ITIN, treaty positions.
Learn more →Tax advisory & planning
Planning for cross-border moves, structuring, and specific tax questions — grounded in current Canadian and US tax law.

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.
