Key takeaways
- From 1 April 2029, VAT-registered persons, including public bodies, must be able to issue and receive VAT invoices as e-invoices unless an exemption applies.
- The government will publish full scope, exemptions and standards 12 to 18 months before the start, giving at least 12 months to prepare.
- A public technical consultation on e-invoicing standards opens in spring 2027. The UK will use Peppol as the core interoperability framework.
- A separate consultation on digital reporting of e-invoice data closes on 20 January 2027. No decision to introduce it has been taken.
- Many accounting software providers are expected to include e-invoicing in their existing packages.
VAT e-invoicing becomes mandatory in the UK on 1 April 2029. On 28 October 2026 the government published an implementation roadmap that sets out the decisions and consultations between now and then. The roadmap confirms the start date, says Peppol will be the core interoperability framework and promises detailed rules at least 12 months before the requirement begins.
What the requirement is
E-invoicing is the exchange of structured invoice data directly between a buyer’s and a supplier’s financial systems. From 1 April 2029, VAT-registered persons, including public sector bodies, must be able to issue and receive VAT invoices as e-invoices. The government intends the requirement to apply broadly. Exemptions will be tightly defined.
E-invoices will not be required for transactions where no VAT invoice is needed, such as exempt, zero-rated or out-of-scope supplies. A commercial e-invoice can still be sent voluntarily. They will also not be required where a digitally excluded or exempt person cannot do e-invoicing.
Key dates
| When | What happens |
|---|---|
| 28 October 2026 | Roadmap published; digital reporting consultation opens |
| 20 January 2027 | Digital reporting consultation closes |
| Spring 2027 | Public technical consultation on proposed UK e-invoicing standards |
| About October 2027 to April 2028 | Full scope, exemptions, standards and obligations published, 12 to 18 months before the start |
| End of 2027 | Guidance for digitally excluded VAT-registered persons |
| 1 April 2029 | VAT e-invoicing requirement starts |
The government says the 12 to 18 month notice gives an implementation period of at least 12 months, so software providers can build, test and release their products.
Standards: Peppol
At Tax Update 2026 the government announced that the UK will adopt Peppol as the core interoperability framework. Peppol lets organisations on different software exchange e-invoices securely through certified Access Points. The roadmap lists common standards, reliable ways to identify the parties to an invoice, governance, software readiness, support for smaller businesses and safeguards for privacy and security as the foundations.
Exemptions and digital exclusion
Exemptions will cover digitally excluded persons and technical points where existing VAT rules on invoicing are incompatible with e-invoicing. MTD for VAT already has criteria for an exemption where it is not reasonable or practical to use computers, software or the internet, for reasons such as age or health. The roadmap says a similar approach is being developed for e-invoicing, with guidance by the end of 2027.
Digital reporting consultation
HMRC opened a consultation on e-invoicing digital reporting on 28 October 2026. It closes on 20 January 2027 and asks businesses, agents and software providers about the opportunities, risks, costs and safeguards. The consultation states that the government has not taken any decisions on whether digital reporting should be introduced or how it might operate.
What the government says it will do for businesses
- Many SMEs will not need separate e-invoicing software. Several providers already offer e-invoicing, including through software used for MTD.
- Several software providers have committed to include e-invoicing in their core package at no additional cost once the requirement applies.
- Free or low-cost digital invoicing products are available for businesses without suitable software.
- Larger or more complex businesses may prefer bespoke solutions integrated into their ERP and accounting systems.
Link to late payment
The roadmap says late payments cost the UK economy £11 billion a year and close 38 businesses every day. Small businesses spend an average of 86 hours a year chasing payments. Industry research cited by the government suggests the smallest businesses could save five hours and forty minutes a week through e-invoicing. The government ties e-invoicing to the Commercial Payments Bill. See our post on the Commercial Payments Bill.
What advisers should do
- Ask clients’ software providers about e-invoicing plans. Find out whether it will be included in existing packages.
- List clients who invoice the public sector. Public bodies are within scope.
- Plan for the 2027 consultations. Standards and digital reporting both affect practice workflows.
- Track exemptions. Clients who may count as digitally excluded should be identified early.
- Read the VAT detail. Our Budget 2026 e-invoicing post covers the Budget measure and costings.
