Sales tax
Sales tax registration is decided by what you do rather than what you earn, and by whether you supply goods or services. Both of those are widely misreported, and getting either wrong means registering with the wrong authority.
Sales tax registration
The turnover threshold that does not exist, the federal and provincial split that decides where you register, and the biometric deadline that removes you from the list.
Selling online
The 1% and 2% collected before the money reaches you, why an IT exporter is outside it, and the final-tax default that can cost a small seller more than the profit.
Sales tax return
Two deadlines rather than one, what happens to your input tax when a supplier does not file, and the penalties that went up fivefold in 2026.
