What counts as taxable sales (high-level)
Many goods and services are taxable, but some may be exempt or zero-rated. Categories can be complex, so do not guess. Use official Revenu Quebec guidance to confirm.
When QST matters for self-employed (high-level)
- Freelancers invoicing clients in Quebec.
- Online sellers shipping to Quebec customers.
- Trades or services performed in Quebec.
- Mixed sales where some items are taxable and others are not.
Whether QST applies depends on official rules and your situation.
Registration basics (high-level)
Registering generally means you charge QST/GST on taxable sales, remit tax, and keep detailed records. In Quebec, GST and QST often move together in practice, but confirm your specific obligations.
What to track (most valuable section)
- Sales invoices (date, customer, taxable amount)
- Tax collected (GST/QST)
- Purchase receipts with tax paid
- Refunds, credits, or adjustments
- Separate business bank account (recommended for clarity)
- Filing and payment confirmations
ITCs/ITRs explained (simple)
Registrants may recover eligible tax paid on business purchases through input credits or refunds. Eligibility depends on official rules and documentation.
