What is a tax point in UK VAT?
HMRC's VAT time of supply manual explains that the tax point is the time when a supply of goods or services is treated as taking place for VAT. It is also called the time of supply. The same manual states that identifying the correct tax point is important for knowing which VAT accounting period includes the tax due on your supplies and for other rules such as partial exemption (HMRC, VAT time of supply manual, accessed 2026).
- Drives which VAT Return period includes output tax on a supply
- Interacts with valid VAT invoices and payment records
- Can be earlier than delivery if you invoice or are paid in advance
- Differs from commercial "due date" wording on an invoice
Example
You deliver fitted shelving on Tuesday and raise a VAT invoice the following Monday within the fourteen-day window. For many businesses the tax point moves to the invoice date rather than the Tuesday delivery, unless you have opted out of that treatment where HMRC allows.
