What is UK Invoice Generator?
A UK invoice generator creates professional invoices compliant with HMRC requirements. For UK businesses, VAT (Value Added Tax) is the primary tax consideration. If your taxable turnover exceeds the VAT registration threshold of £90,000, you must register for VAT and include your VAT registration number on all VAT invoices. The standard VAT rate is 20%, with a reduced rate of 5% applying to certain goods and services. The Making Tax Digital (MTD) initiative requires VAT-registered businesses to keep digital records and submit VAT returns through compatible software. HMRC requires businesses to retain invoice records for a minimum of 6 years.
How to use
- Enter your business name and address. If VAT-registered, add your VAT registration number in the Tax ID field.
- Fill in your client's name and billing address. For B2B clients, note their VAT number if reverse charge applies.
- Add line items with clear descriptions, quantities, and unit prices — amounts exclude VAT at this stage.
- Set the tax rate to 20% for standard-rated supplies, 5% for reduced-rate, or 0% for zero-rated goods.
- Review the VAT amount and total including VAT in the invoice preview.
- Download as PDF and send to your client — retain a copy for your own HMRC records.
Why it matters
A VAT invoice must contain specific mandatory fields — including your VAT number, the VAT amount charged, and the supply date — for HMRC to accept it as valid for a VAT reclaim. For B2B clients who are themselves VAT-registered, receiving a proper VAT invoice is essential: without it, they cannot reclaim input tax on their VAT return. An invoice missing required fields can result in the VAT reclaim being denied, creating a downstream dispute with your client. Correct VAT invoicing is not just good practice — it is a legal requirement for VAT-registered UK businesses.
Pro tip
If your annual turnover is below the £90,000 VAT registration threshold, you are not required to register for VAT — but you can choose to register voluntarily. For businesses primarily serving other VAT-registered businesses, voluntary registration can actually enhance credibility and allows you to reclaim VAT on your own business expenses. Run the numbers: if your input VAT (VAT you pay on purchases) is significant, voluntary registration may benefit you even below the threshold.
