What's included
Canadian & US tax coverage
GST, HST, PST (BC, SK, MB), QST (QC), and all 45 US sales-tax states. Rates are maintained by Sour Sync — always current.
Calculated per order
Tax is calculated at checkout based on the buyer's shipping address — not a flat rate. Your buyers are charged exactly the right amount.
Tax shown on receipts
Every buyer receipt breaks out the tax amount separately. Your Business Number / GST# is printed on invoices for compliance.
CRA & IRS ready
Transaction records include jurisdiction, rate, and amount for each sale. Export for your accountant or feed into your preferred bookkeeping tool.
Zero configuration
Enter your province/state and Business Number in Settings → Taxes. Sour Sync handles the rest — no rate tables to maintain.
Rate updates included
When governments change tax rates, Sour Sync updates automatically. You'll never collect the wrong amount because of a stale rate table.
Included in every plan. Free.
No add-on required. Automatic tax calculation at checkout is built into every Sour Sync store — from day one.
