Section 14 - Change in rate of tax in respect of supply of goods or services.

Change in tax rate determines time of supply by reference to invoice or payment dates, whichever is earlier.

Change in rate of tax fixes the time of supply by reference to invoice and payment timings: for supplies before the rate change, the earlier of invoice or payment after the change governs, except where one of those events occurred before the change in which case that earlier event controls; for supplies after the change, outcomes depend on whether invoice or payment occurred before or after the change with the relevant event date determining time of supply. The 'date of receipt of payment' is the earlier of accounting entry or bank credit, and a bank credit more than four working days after the change is treated as the receipt date.
