UK VAT on exports: zero rating and proof of export (Notice 703)
UK businesses can zero rate goods they export outside the UK, but only if the goods leave within the time limit and the business holds valid proof of export. HMRC VAT Notice 703, last updated on 4 March 2026, sets out the conditions; without the evidence, the supplier must account for VAT at the UK rate.

Direct and indirect exports
In a direct export the UK supplier arranges the transport and sends the goods out of the UK. In an indirect export the overseas customer, or its agent, collects the goods from the supplier and arranges the export. Both can be zero rated if the conditions are met, but goods for the customer's own non-commercial use carried in accompanied baggage cannot be zero rated as an indirect export.
The time limit starts at the time of supply, which in most cases is the earlier of the date the goods are sent or taken away and the date full payment is received. Goods must normally leave the UK and evidence must be obtained within 3 months, or 6 months where the goods are first processed or incorporated into other goods.
What the evidence must show
- The supplier.
- The customer.
- An accurate, non-contradictory and full description of the goods, including quantities.
- A value consistent with the invoice.
- The export destination.
- The mode of transport and the route of the export movement.
Post, courier and ex works sales
For goods sent by post or courier, evidence depends on the service: a certificate of posting for letter post, customs declarations and collection receipts for parcels, and for couriers usually the air waybill number on the invoice or a track-and-trace confirmation. Replacement or photocopied evidence must be marked 'Duplicate evidence of export' and authenticated and dated by the issuing company.
Ex works sales are risky because the customer controls the export: if it does not send the evidence, the supplier still owes the VAT. HMRC suggests writing the evidence requirements into the sales contract and taking a deposit equal to the VAT that would be due.
Step by step
- Decide whether the sale is a direct or an indirect export.
- File the export declaration and keep the departure confirmation with the MRN or DUCR.
- Collect authenticated transport documents that match the invoice.
- Check that the goods leave and the evidence is in hand within 3 months of the time of supply.
- For ex works sales, put the evidence requirement in the contract and consider a deposit equal to the VAT.
- Keep the proof of export for 6 years and have it ready for a VAT officer.
Documents you usually need
- Export declaration and departure confirmation (MRN or DUCR)

Common problems and how to avoid them
What to do: Account for VAT at the UK rate; if the evidence arrives later, zero rate the supply and adjust in the period you receive it.
What to do: The supplier is liable for the VAT; use contract terms and a deposit equal to the VAT for future ex works sales.
What to do: Evidence must give an accurate, non-contradictory description and a consistent value; ask for corrected documents.
What to do: A replacement or photocopy must be marked 'Duplicate evidence of export', authenticated and dated by the issuing company.
