Sales tax summary and the GST/HST return

Tax collected against tax paid, and the CRA line numbers.

Reports → Sales tax shows tax collected on invoices against tax paid on bills, and the net owing — the figure you remit. On Business and Enterprise the GST/HST return lays the same figures out by CRA line number and exports to Excel for your accountant.

Rates are set in Settings → Books & tax; each invoice and bill line carries its own rate, so mixed taxable and non-taxable work on one document is fine.
