What is the UK Making Tax Digital B2B e-invoicing mandate for 2029?
Effective: 2029-04-01 · Authority: HM Revenue & Customs (HMRC)
The United Kingdom will enforce mandatory B2B and B2G e-invoicing for all VAT-registered businesses starting April 2029. Operating on a decentralized 4-corner exchange model, the mandate eliminates paper and PDF invoices in favour of structured, machine-readable data. Real-time reporting (RTR) is not included in the initial 2029 mandate but may be explored in later phases.
Who does the UK 2029 e-invoicing mandate apply to?
The April 2029 mandate covers all VAT-registered businesses in the UK for B2B and B2G invoice exchanges:
- All VAT-registered businesses — no turnover threshold exclusion
- Both B2B (business-to-business) and B2G (business-to-government) transactions
- Structured, machine-readable invoice formats replacing paper and PDF
- Decentralized 4-corner exchange model — no centralized government routing portal
How does the UK 4-corner e-invoicing model work?
The UK's decentralized 4-corner model routes structured invoices between trading partners via certified Access Points: Supplier → Supplier's Access Point → Buyer's Access Point → Buyer. The UK government plans a decentralized interoperable network rather than a single central portal, contrasting with France's PPF architecture.
