E-invoicing if you are
not VAT registered

Most sole traders are not VAT registered. If that is you, the headlines about "mandatory e-invoicing from 2029" are less alarming than they sound. The mandate attaches to VAT invoices, and a business that is not VAT registered does not issue them. The government said so directly in its response to the 2025 consultation. But there is more to it than "it does not apply", and this guide covers the parts that still matter.

Why you are outside the mandate

A VAT invoice is a specific document. Only a VAT-registered business can issue one, because it shows the business's VAT registration number and the VAT charged. If you are not registered, you issue ordinary invoices, with no VAT and no VAT number. The guide on invoicing without a VAT number covers what they must show. Since the mandate as announced is for "all VAT invoices", your ordinary invoices are not covered.

Notice the careful wording in the government's response: businesses "not required" to register "and choose not to be registered". If your turnover goes over the £90,000 threshold, you must register, and your invoices become VAT invoices. If you register voluntarily, the same applies.

Your obligations by situation

Qualifying income for MTD for Income Tax is your gross income from self-employment and property, before expenses. Turnover for VAT is your VAT taxable turnover. They are different measures, so check each. The MTD requirement checker and the VAT registration checker do the sums.

The chart shows why many small businesses will meet Making Tax Digital well before they meet e-invoicing. A sole trader with £35,000 of income is in MTD from April 2027 but, unless they register for VAT, outside the e-invoicing mandate.

What still affects you

Being outside the mandate does not mean e-invoicing passes you by entirely:

• Your VAT-registered customers. From April 2029 their own systems will be built around receiving invoices as data. Your ordinary invoices are not VAT invoices, so the mandate does not require you to change, but a customer used to e-invoices may find a PDF invoice slower to process. How ordinary invoices from unregistered suppliers fit into customers' systems is not yet set out.
• Invoices you receive. Suppliers do not need to issue VAT invoices to customers who are not VAT registered, according to HMRC's VAT guide. Whether suppliers will send you e-invoices, PDFs or both will depend on their systems and the final rules.
• Public sector customers. Some public bodies already prefer or require e-invoices through their procurement systems, whatever your VAT status.
• Your growth. If you are heading for the VAT threshold, you are heading into the mandate.

Should you adopt e-invoicing anyway?

Nothing obliges you to, but some small businesses may find reasons to:

The government's case for e-invoicing leans heavily on late payment: industry research quoted in its response found a 20% reduction in late payments on adoption. Late payment hits small suppliers hardest, so if your customers can receive e-invoices, there may be a benefit even without an obligation.

If you register for VAT

Registration changes the picture. From your registration date you charge VAT and issue VAT invoices to VAT-registered customers, and from April 2029 those must be e-invoices. You must register if your taxable turnover over the last 12 months goes over £90,000, or you expect it to go over £90,000 in the next 30 days alone. You can also register voluntarily below the threshold, which some businesses do because most of their customers can reclaim the VAT. If you are weighing voluntary registration, factor in that e-invoicing will come with it. The guide on who is in scope covers VAT-registered businesses in detail.

Making Tax Digital is the bigger change for most

For most sole traders who are not VAT registered, the change that matters sooner is Making Tax Digital for Income Tax. It requires digital records and quarterly updates through compatible software once your qualifying income passes the threshold. The two regimes point the same way: records kept in software, not spreadsheets and paper. Choosing software that handles your invoicing and your MTD obligations together means that, if you ever register for VAT, the move to e-invoicing is a setting, not a new system. The guide on e-invoicing and MTD explains how they relate.

Two worked examples

Priya, a freelance illustrator, earns £28,000 a year from publishers and design agencies and is not VAT registered. She is outside the e-invoicing mandate, because she issues ordinary invoices. Her qualifying income is below the £30,000 MTD threshold for April 2027 but above the £20,000 threshold for April 2028, so under the announced thresholds MTD for Income Tax reaches her from April 2028. She will meet MTD long before e-invoicing, and only meets e-invoicing if she registers for VAT.

Tom, a joiner, turns over £84,000, mostly from homeowners with some work for a local builder. He is outside the mandate today, and his qualifying income puts him in MTD for Income Tax already. A couple of large jobs could push his turnover over £90,000. If he registers for VAT after April 2029, his invoices to the builder become VAT invoices, and they must be e-invoices. His invoices to homeowners stay outside the mandate. Choosing software now that can do e-invoicing later saves him a second switch.

What the government has promised small businesses

The consultation response returns repeatedly to small businesses. It says ensuring simple, low-cost solutions for small and micro businesses will need to be a priority, that the government wants a diverse and competitive market offering affordable e-invoicing products, and that support for businesses will be a key part of the implementation roadmap. It also notes that, as with Making Tax Digital, it expects products at a range of price points, and that several MTD providers focused on small businesses already offer e-invoicing. None of this is a funding commitment, and the detail is due with the Budget 2026 roadmap.

Getting your invoicing ready anyway

Good habits now make any future change painless:

1. Invoice from software, so each invoice already exists as structured data.
2. Use a clear numbering sequence. The invoice number generator sets one up.
3. Keep customer details accurate, including legal names, addresses and, for business customers, their VAT numbers where they have them.
4. Record payments against invoices, so you can see what is outstanding.
5. Keep an eye on your turnover against the VAT threshold.

Keeping records either way

Whatever your VAT status, the record-keeping rules for your own tax do not change with e-invoicing. As a sole trader you must keep records of your income and expenses, including copies of your invoices, for at least 5 years after the 31 January submission deadline of the relevant tax year. Under Making Tax Digital, those records must be digital. The guide on how long to keep invoices covers the detail, and most sole traders use cash basis accounting, where income counts when you are paid rather than when you invoice.

Common questions

Will HMRC see my invoices? The mandate is about VAT invoices exchanged between businesses, and the government has said there will be no real-time reporting in 2029. Your ordinary invoices are not affected.

Do I need to tell anyone I am not VAT registered? No. Your ordinary invoices simply do not show a VAT number or charge VAT, and customers can see that.

Could the scope change? The mandate as announced covers VAT invoices. Some respondents suggested thresholds or exemptions, and the details are due in the Budget 2026 roadmap. The e-invoicing hub will record any change.

Is a PDF invoice still fine for me? For a business that is not VAT registered, the mandate does not change the invoices you issue. A clear PDF invoice with everything required remains fine. What e-invoicing means is explained in the glossary.
