Questions
Asked before almost every first meeting
More answers on prices, deadlines and working with the CRA are on the FAQ page.
All questionsAre your prices fixed?
Monthly packages are fixed fees agreed in your engagement letter. One-off services are quoted before we start. Prices are in Canadian dollars and HST is added.
When is my personal tax return due?
April 30 for most people; June 15 if you or your spouse or common-law partner were self-employed. Any balance owing is due April 30 either way.
Can you take over from my current accountant?
Yes. With your permission we request last year's working papers and returns from your previous accountant and pick up from there.
Why do you add HST?
Accounting services are taxable supplies. In Ontario the HST rate is 13%, so a $595 monthly package is $672.35 including HST.
