United Kingdom Budget 2025 Introduces Mandatory VAT E-Invoicing from April 2029

The UK government has confirmed that, from 1 April 2029, all businesses will be required to issue VAT invoices in a specified electronic format.
On 26 November 2025, the government published Budget 2025open_in_new, setting out a major milestone in the country’s tax digitalisation strategy.

What the announcement confirms

• Mandatory electronic VAT invoices for all UK businesses from 1 April 2029.
• A detailed implementation roadmap to be published at Budget 2026 following stakeholder consultation.
• Reform is positioned as part of a broader investment into HM Revenue and Customs.

Policy objectives

The reform is expected to:

• Reduce administrative burdens
• Improve reporting accuracy
• Accelerate payment cycles
• Help close the VAT gap

The measure also aligns the UK with international developments, particularly the EU’s VAT in the Digital Age initiativeopen_in_new, which introduces cross-border e-invoicing requirements from July 2030.

What happens next

A full technical framework, including format standards, reporting mechanisms, and transition phases, will be developed during 2026. Businesses will have a multi-year preparation window before the 2029 go-live date.
