Mandatory VAT E-Invoicing from 1 April 2029: What HMRC's New Roadmap Means for Your Business
HMRC and the Department for Business and Trade published a roadmap on 28 October 2026 confirming that all VAT-registered businesses must be able to issue and receive VAT invoices as e-invoices from 1 April 2029, using the Peppol network.

From 1 April 2029, every VAT-registered business in the UK will need to be able to issue and receive VAT invoices as e-invoices. HMRC and the Department for Business and Trade set out the timetable in a roadmap published on 28 October 2026, alongside the Autumn Budget, and confirmed the UK will use the Peppol network.
A PDF emailed to a customer will not count. An e-invoice is structured data sent between systems, so most businesses will meet the rule through their accounting software rather than by changing how they work day to day.
What the roadmap confirms
The roadmap says: "From 1 April 2029, VAT-registered persons (including public sector bodies) will need to be able to issue and receive VAT invoices as e-invoices." The key points are:
- Scope. Supplies between VAT-registered businesses in the UK where a VAT invoice is needed, plus VAT-registered public bodies. Overseas businesses registered for UK VAT are treated the same as UK businesses.
- Out of scope. Sales to consumers and transactions that do not need a VAT invoice, though these can be e-invoiced voluntarily. Cross-border e-invoicing is not required.
- Exemptions. These are described as narrow. The main one is for digitally excluded people, modelled on the existing Making Tax Digital for VAT criteria.
- Network. The UK will use Peppol as its framework. Businesses will normally connect through their software provider's certified Peppol Access Point, and HMRC will become the UK Peppol Authority.
The Budget's Overview of Tax Legislation and Rates (measure 1.58) gives HMRC the legal power to make regulations "requiring VAT invoices to be issued and received in a prescribed electronic format".
The timetable to 2029
The roadmap sets out the main steps:
- Spring 2027: Finance Bill legislation expected to become law, and public technical consultations on UK e-invoicing standards and Access Point certification.
- October 2027 to April 2028: final requirements published, covering scope, exclusions, standards, business identifiers and service-provider rules.
- By April 2028: details of the digital exclusion exemption and updated VAT guidance.
- Summer 2028: readiness testing with software providers.
- Autumn 2028 or early 2029: secondary legislation expected.
- 1 April 2029: go-live.
The roadmap says there are no planned changes to the requirements after April 2028 unless stakeholder feedback makes them necessary.
A separate consultation on digital reporting
HMRC has also opened a consultation on e-invoicing digital reporting, which closes on 20 January 2027. It asks whether the structured data created by e-invoicing could be used for defined purposes, such as helping businesses correct errors earlier, speeding up VAT repayment checks and cutting information requests. HMRC states that "No decision has been taken to introduce digital reporting" and that it has no preferred model. It also says digital reporting would not mean HMRC automatically receives every e-invoice. Businesses, accountants and software providers can respond.
Help for small businesses
The roadmap says many small businesses will be able to e-invoice through existing accounting or Making Tax Digital software, and that several software providers have committed to include e-invoicing at no extra cost. Businesses that are not VAT-registered will be able to use e-invoicing without registering for VAT. Guidance will come through GOV.UK and the Business Growth Service.
What to do now
This section is editorial guidance.
- Ask your software provider. Check whether your accounting or invoicing tool plans to support Peppol e-invoicing and whether it will charge extra.
- Clean up customer and supplier data. E-invoices rely on accurate business identifiers, so make sure VAT numbers and company details are correct.
- Avoid building on spreadsheets. If you invoice from Word or Excel templates, plan a move to software well before 2029.
- Have your say. If digital reporting would affect your business, the consultation is open until 20 January 2027.
