Under HMRC rules, a VAT-registered UK business must give a VAT invoice showing a unique invoice number, the date, its name, address and VAT registration number, the customer's name and address, a description of what was sold, the price excluding VAT, the VAT rate and the VAT amount. For a retail sale of £250 or less (including VAT) it can give a simplified invoice instead, with fewer details.
This is general information, not tax advice. VAT rules and thresholds are set by HMRC and change periodically — confirm current requirements at gov.uk or with an accountant before relying on this for compliance.

Who Needs to Issue VAT Receipts?
Only VAT-registered businesses can — and generally must — issue VAT invoices/receipts for taxable sales. A business below the VAT registration threshold doesn’t charge VAT (unless it has registered voluntarily) and shouldn’t show a VAT breakdown on its receipts, since it isn’t registered to collect it.
Full VAT Invoice vs. Simplified VAT Invoice
HMRC distinguishes between two formats:
Full VAT invoice
Required for most B2B transactions and higher-value sales. Must include the buyer’s name and address, a unique invoice number, the seller’s VAT number, the tax point (date of supply), a description of goods/services, the quantity, the price excluding VAT, the VAT rate, and the VAT amount.
Simplified VAT invoice
Permitted for retail supplies under a certain value threshold (commonly used by shops and restaurants). Requires fewer details — typically the seller’s name, address and VAT number, the date, a description of the goods, and the total including VAT, with the VAT rate shown.
What a Standard VAT Receipt Should Include
- Unique, sequential invoice/receipt number
- Seller’s business name, address and VAT registration number
- Date of supply (tax point)
- Description of goods or services
- Net amount (excluding VAT)
- VAT rate applied (standard, reduced, or zero-rated)
- VAT amount, shown separately
- Total amount including VAT
Common Mistakes UK Businesses Make
- Charging VAT without being VAT-registered, or forgetting to display the VAT number once registered
- Not separating the VAT amount clearly from the net price
- Using the wrong VAT rate for a specific good or service (standard, reduced, or zero-rated all apply to different categories)
- Missing the tax point date, which determines which VAT period the transaction falls into
Using a Receipt Generator for VAT-Compliant Receipts
Our free receipt generator covers the universal fields — itemized goods/services, tax rate and total, shown separately — which map directly onto VAT receipt requirements. VAT-registered businesses should add their VAT number in the business details or notes field to keep every receipt compliant — our itemized retail and restaurant templates are both built with this exact tax breakdown.
Full VAT Invoice: The Complete Checklist
HMRC’s record-keeping guidance (VAT Notice 700/21) lists what a full VAT invoice must show:
- A unique, sequential invoice number
- The time of supply (tax point)
- The date of issue, if different from the time of supply
- Your business name, address and VAT registration number
- The customer’s name and address
- A description that identifies the goods or services
- For each item: the quantity, the VAT rate and the price excluding VAT
- The total amount excluding VAT
- The rate of any cash discount offered
- The total VAT charged, in sterling
Simplified VAT Invoice (£250 or Less)
If a supply is £250 or less including VAT, you can give a simplified invoice instead. It only needs:
- Your name, address and VAT registration number
- The time of supply (tax point)
- A description of the goods or services
- For each VAT rate: the total payable including VAT, and the VAT rate charged
Simplified invoices can’t be used for exempt supplies. Many shops, cafés and trades use them for everyday sales.
Worked Example: VAT at 20%
| Price excluding VAT | VAT at 20% | Total including VAT | |
|---|---|---|---|
| Bathroom tiling (labour) | £400.00 | £80.00 | £480.00 |
| Tile adhesive | £25.00 | £5.00 | £30.00 |
| Total | £425.00 | £85.00 | £510.00 |
Because this sale is over £250, the customer should receive a full VAT invoice. To work backwards from a VAT-inclusive price at 20%, divide by 1.2: £120 including VAT is £100 plus £20 VAT.
Registration Threshold and Record Keeping
You must register for VAT when your taxable turnover for the last 12 months goes over £90,000. Until you are registered, you must not charge VAT or show a VAT number on your receipts. Once registered, keep your VAT records — including copies of the invoices you issue — for at least 6 years. Records can be kept digitally.
Do I need to charge VAT if I’m not registered?
No — and you shouldn’t show a VAT breakdown on receipts if you’re not VAT-registered, since you have no VAT number to charge against.
What’s the current VAT registration threshold?
This threshold is set by HMRC and reviewed periodically — check gov.uk for the current figure rather than relying on any fixed number, since it does change.
Can I issue a simplified VAT invoice for any sale?
No — simplified invoices are generally only permitted for retail supplies under a specific value threshold; larger or B2B transactions typically require a full VAT invoice.
Is a digital VAT receipt acceptable to HMRC?
Yes — HMRC accepts digital VAT records as part of its Making Tax Digital requirements, as long as the receipt contains all required fields and is properly retained.
Do VAT invoice numbers have to be sequential?
Yes. HMRC requires a sequential number, based on one or more series, that uniquely identifies each invoice. You can run separate series (for example per branch) as long as each number is unique.
