Invoice Requirements for the United Kingdom (Cross-Border)

The UK levies VAT at 20% with detailed VAT-invoice rules but no e-invoicing mandate; post-Brexit exports also need a customs commercial invoice.

E-invoicing: Not mandatory VAT 20% Complexity: Low

The UK applies VAT (standard rate 20%) but has no e-invoicing mandate as of 2026. A compliant VAT invoice must show a unique sequential number, the supplier's VAT registration number, the tax point (supply date), a description of the goods or services, the net amount, and the VAT rate and amount per rate, plus the total. For cross-border B2B services the reverse charge usually applies and the invoice should be annotated accordingly. Since Brexit, goods moving to or from Great Britain also require a customs commercial invoice (HS codes, Incoterms, origin, weights). Retain invoices for 6 years.
