The Government’s push towards mandatory electronic invoicing is intended to modernise the UK tax system—but many small businesses still appear unclear about what the changes actually involve.
At the Autumn Budget, Chancellor Rachel Reeves confirmed that all VAT-registered businesses will be required to issue invoices electronically from April 2029. The move forms part of a wider effort to digitise tax reporting and improve efficiency across the system.
Yet despite the scale of the change, awareness among SMEs remains surprisingly low.
Research commissioned by HMRC and carried out by IFF Research found that many smaller businesses have little understanding of e-invoicing requirements ahead of the rollout. Among 800 SMEs surveyed across sectors including manufacturing, transport and business services, a quarter said they were “not at all familiar” with the term “e-invoicing,” while 69% claimed they had never used it.
Perhaps more strikingly, 91% said they had not seen any HMRC guidance on the upcoming changes.
The findings have fuelled concerns that smaller firms may not have enough time or support to prepare—particularly given the lack of a phased introduction tailored to businesses with limited digital resources.
However, the picture is not entirely straightforward. The Association of Taxation Technicians noted that some respondents who initially said they did not use e-invoicing later described systems and processes that effectively met the definition. In several cases, those responses were later reclassified.
That suggests awareness may be lagging behind actual adoption.
Encouragingly, 59% of SMEs said they were at least somewhat familiar with e-invoicing, while 29% reported previous use. Among businesses already using digital invoicing systems, Sage emerged as the most common platform, used by 46% of respondents, followed by Xero at 17% and QuickBooks at 9%.
Still, gaps remain. Around 5% of businesses reported using no accounting software at all, with the highest concentrations found in manufacturing and construction—sectors where digital adoption can vary widely.
The transition to e-invoicing is still several years away, but the research highlights a growing challenge for policymakers: modernising the tax system is not just about introducing new rules, but ensuring businesses understand them and have the tools to adapt.
For SMEs, the message is becoming clearer. While many may already be closer to compliance than they realise, preparation—and awareness—will be key as the 2029 deadline approaches.
