Do you speak Tamil or Sinhala?
Yes — most of our clients are served in Tamil, and we also serve clients in Sinhala. You can do everything, from the first call to the final review, in English, Tamil or Sinhala.
How much does a personal tax return cost?
Basic personal returns start at $75 per person. Extras like rental income are priced up front (rental adds $60) — see the pricing page for the full list. You'll always know the fee before we start.
What should I bring?
Your slips (T4, T5, T4A…), last year's Notice of Assessment, receipts for deductions (RRSP, medical, donations, childcare), and rental or business records if they apply. Not sure? Call us — we'll tell you exactly what your situation needs.
Can you fix past years or handle CRA letters?
Yes. We file adjustments for previous years, catch up unfiled returns, and respond to CRA reviews, audits, and disputes on your behalf.
Do I need an appointment?
Walk-ins are welcome, but during tax season an appointment saves you waiting. Book online in one minute, or call and we'll set a time.
