I recommend Olha Vozna as a very professional accountant. She helps me with my tax returns and GST filings, does everything quickly and clearly, and always explains all the details. I am very satisfied with her work.
I had a consultation and was very impressed with the quality of service. All my questions about self-employment, international taxes, CPP contributions, and GST registration were answered in detail and in a way that was easy to understand. The information was clear, practical, and tailored to my situation, which gave me much more confidence moving forward. I truly appreciated the professionalism, patience, and ability to explain complex topics in simple terms. It was a very valuable and informative meeting, and I would highly recommend these services to anyone looking for reliable tax and accounting advice in Canada.

How sales tax works here
Alberta is the only province with no PST or HST. You only ever charge the 5% federal GST β there's no separate provincial sales tax to register for, collect or file. On a $100 sale that's $5 GST and $105 in total.
You generally have to register for GST once your taxable sales pass $30,000; below that it's optional. Basic groceries and many health and financial services are zero-rated or exempt, so a real invoice can differ from a flat 5%.
FAQ
No β Alberta has never had a provincial sales tax. You only deal with the 5% federal GST, which is why Alberta's total sales tax is the lowest in the country.
Generally once your taxable sales pass $30,000 β measured over a single calendar quarter or the last four consecutive quarters. Under that you're a "small supplier" and registering is optional. The $30,000 counts your worldwide taxable sales and those of anyone you're associated with, not your profit.
Switch the calculator to "Take GST/HST out of a total" and enter the tax-included amount. It divides by one plus the combined rate to find the price before tax, then shows the tax on top.
