United Kingdom Plans Mandatory E-Invoicing for B2B and B2G Transactions by 2029

• The UK plans to make e-invoicing mandatory from April 2029 for VAT invoices in B2B and B2G transactions.
• The new requirement will apply to structured, machine-readable electronic invoices, not PDF invoices sent by email.
• HMRC and the Department for Business and Trade will publish an implementation roadmap at Budget 2026, with full guidance, standards, technical specifications, and legislation due by the end of 2027–2028.
• The reform is intended to create a common framework for exchanging invoice data, but the final technical format and transmission rules have not yet been set.
• The mandate is expected to affect both sales and purchase invoices and will be developed with input from businesses and software providers.
