What to include on a UK VAT invoice
UK businesses use invoices every day to request payment and support tax records. When you are VAT registered, invoices also underpin VAT accounting — so the fields on the document matter for HMRC, your clients, and Making Tax Digital (MTD) workflows.
This guide explains what UK invoices and VAT invoices usually need to include. It is general information, not tax advice. Check GOV.UK or speak to an accountant if you are unsure what applies to your business.
Quick answer
GOV.UK says invoices should include a unique identification number, your company name and address, the customer name and address, a clear description of what you are charging for, the supply date, the invoice date, the amount charged, VAT amount if applicable, and the total amount owed.
If you are VAT registered, you must charge VAT on taxable supplies unless exempt, show your VAT registration number, and display VAT separately on invoices where required.
Standard UK invoice fields
Whether or not you charge VAT, a clear UK invoice usually includes:
- Unique invoice number — sequential and unique for your records
- Your business name and address — and contact details
- Customer name and address — the billing entity
- Description of goods or services — specific enough to identify the supply
- Supply date — when goods or services were provided (or an indication if different from invoice date)
- Invoice date — when the invoice was issued
- Amounts — unit prices, quantities, subtotals
- VAT — only if you are VAT registered and VAT applies
- Total amount owed — the figure the customer must pay
- Payment terms — when and how to pay

VAT invoice requirements
When your business is VAT registered, GOV.UK requires you to:
- Charge VAT on taxable goods and services (unless exempt or outside scope)
- Show your VAT registration number on invoices
- Show VAT separately on invoices where required (full VAT invoices for most B2B supplies)
Do not add VAT to invoices if you are not VAT registered. Doing so can create serious compliance problems.
Full vs simplified VAT invoices
Most business-to-business supplies use a full VAT invoice with all standard fields and VAT shown separately. In limited circumstances simplified invoices may be allowed for supplies under £250 — see HMRC VAT Notice 700 and your accountant for detail.
Sole traders and limited companies
Sole traders trading under a business name may need to include:
- The business name used
- Your own name
- An address where legal documents can be delivered to you
Limited companies should show the full company name as registered at Companies House, the company address, and company registration number where required on invoices and stationery.
Record keeping and HMRC
HMRC expects you to keep records that support the figures in your tax returns. Invoices are central evidence for:
- Sales income and dates
- VAT charged on supplies
- Customer identity for B2B supplies
Organised invoice numbering, consistent descriptions, and archived PDFs make year-end and VAT periods less stressful — especially when your accountant asks for a clean trail.
Making Tax Digital (MTD) context
Making Tax Digital for VAT requires VAT-registered businesses to keep digital records and submit VAT Returns using compatible software.
Clear invoices support MTD because they document:
- What you supplied
- When you supplied it
- How much VAT you charged
InvoiceFeed is not positioned as MTD filing software. It helps with everyday invoicing — creating professional invoices, storing clients, and tracking payment status. Use GOV.UK and your accountant to choose MTD-compatible filing tools.
