I was facing plenty of problems with the CRA. My previous accountant messed up my bookkeeping and HST. Expertax helped me re-organize my books, and get back on track. They are very professional and understood my situation. Thanks Expertax!

I was looking for a business plan to start my new clinic. Expertax helped me with my business plan, getting a loan from the bank, and now doing my bookkeeping and payroll every month. A-Z service with no fuss!
Their knowledgeable staff helped me save taxes with my corporation and personal files. Also their monthly financial statements help me track my company’s progress. Best accounting office I’ve dealt with and referred a few friends and family over!

I was referred to Expertax by a friend for an Audit I had. Their professional and timely work saved me and my company. They take the time to understand my line of work and how my company operates. Not like the other accounting firms, they don’t treat you like a client; they welcome you to the Expertax family!
