WHY CHOOSE ADIAN
Why Incorporated Business Owners Choose Adian CPA
What sets us apart — and what it means for you.
Big 4 audit background
Every return is prepared to the standard of a senior CPA — not delegated to a junior. You get technical accuracy, not assembly-line filing.
Fixed-fee engagements
You know the fee before we start. No hourly billing, no surprise invoices. Scope is confirmed in writing before any work begins.
Canadian domestic tax only
We do not take on engagements outside our expertise. If your situation involves US tax or international matters, we will tell you immediately and refer you to the right firm.
T1 and T2 prepared together
Where we handle both returns, your salary/dividend split, RRSP room, and personal integration are reviewed together — not in isolation.
Technical depth on CCPC matters
RDTOH, GRIP, CDA, SBD, TOSI, s.85 rollovers — we work with these daily. Our service pages and client communications reflect that depth.
Written tax plans, not verbal advice
Every tax planning engagement delivers a written plan with ITA section references. You have a documented basis for implementation.
SERVICE AREAS
We Serve Incorporated Businesses Across Canada
Adian Professional Corporation provides T2 corporate tax, compilation, and tax planning services to incorporated businesses and CCPCs in all Canadian provinces and territories except Quebec. Quebec corporations require a separate provincial CO-17 return filed with Revenu Québec — we do not hold registration to file Quebec provincial corporate returns.
While our office is in Mississauga, Ontario, all engagements are conducted remotely. We work with clients from British Columbia to Newfoundland. You provide year-end records digitally; we prepare, review, and file electronically. Geography is not a barrier.

Quebec not served: Quebec corporations are subject to a separate provincial corporate tax return (CO-17) filed with Revenu Québec. We do not file Quebec provincial corporate returns. If your corporation has a Quebec permanent establishment, we are not the right firm.
