VAT Receipt vs VAT Invoice: What’s the Difference?

Quick answer: A VAT invoice is a legal document that proves VAT was charged — it carries the supplier's VAT number, the rate applied and the VAT amount, and it is the primary evidence HMRC accepts for reclaiming input tax. A VAT receipt is proof that money was paid. A till receipt can double as a VAT invoice, but only if it shows the supplier's VAT number, the VAT rate and the VAT charged — and only for supplies of £250 or less including VAT. Above £250 you need a full VAT invoice; a payment confirmation, a bank statement or a pro forma invoice will never do the job on its own.

The difference in one sentence

An invoice asks for payment and records the VAT; a receipt confirms payment has been made. Almost every mistake with VAT receipts comes from treating the two as interchangeable. A receipt tells HMRC you paid somebody. A VAT invoice tells HMRC how much of what you paid was VAT, who charged it and on what supply — and that is what your input tax claim depends on.

VAT Notice 700/21 puts it plainly: the VAT invoices you receive are "the primary evidence for you to recover VAT you have incurred as input tax". A receipt is not mentioned as evidence at all. A till receipt that carries the right fields is a VAT invoice in HMRC's eyes — but one that lacks the VAT fields is, for reclaim purposes, just proof you spent money.

What a VAT invoice is

A VAT invoice is an invoice that contains the information the VAT rules require; most ordinary commercial invoices already meet the test. Only a VAT-registered business can issue one, and if you are registered you must issue one whenever you supply standard-rated or reduced-rated goods or services to another VAT-registered person, normally within 30 days of the supply.

A full VAT invoice must show eleven things, set out in section 4 of Notice 700/21:

1. A sequential number, based on one or more series, that uniquely identifies the document
2. The time of supply — the tax point — and the date of issue, where it differs
3. Your name, address and VAT registration number
4. The name and address of the person the goods or services were supplied to
5. A description identifying the goods or services supplied
6. Per line: the quantity, the VAT rate and the amount payable excluding VAT
7. The gross total amount payable, excluding VAT
8. The rate of any cash discount offered
9. The total amount of VAT chargeable, expressed in sterling
10. The unit price

Two fields do most of the work: the VAT registration number, which lets HMRC link the supplier to the transaction and confirms the person charging VAT was entitled to charge it, and the VAT amount in sterling, which is the figure your customer puts in Box 4. Miss either one and the document cannot support an input tax claim. Our VAT invoice guide walks through the same rules with a full example invoice.

There are narrow exceptions: no invoice is needed if it would only cover exempt or zero-rated sales within the UK, where your customer operates a self-billing arrangement or you issue authenticated receipts, or for gifts of goods on which VAT is due and sales under a second-hand margin scheme. Our VAT tax point guide explains how the time of supply on the invoice decides which return period the VAT falls into.

What a VAT receipt is

A receipt confirms payment: a till receipt, a card-machine slip, an email saying "payment received", or a stamped invoice marked "paid". It answers one question — did the money change hands? — with a date, an amount and the name of the business that took the money.

The confusion starts because "receipt" means two things. In everyday speech, any proof of payment is a receipt. In VAT practice, a till receipt from a VAT-registered retailer is often also a simplified VAT invoice, because it carries the supplier's VAT number, the VAT rate and the total including VAT. But a card-machine slip showing only the total and the last four digits of your card is a receipt and nothing more: it proves you paid £48, not that £8 of it was VAT. HMRC cannot accept it as evidence of input tax.

That is the test for any receipt you hold: does it show the supplier's VAT number, the VAT rate and the VAT charged? If it shows all three, it can support a reclaim. If it shows none of them, it cannot.

VAT receipt vs VAT invoice at a glance

When a receipt is enough to reclaim VAT

For supplies of £250 or less including VAT, HMRC lets the supplier issue a simplified VAT invoice instead of a full one — the document most people mean when they say "VAT receipt". It must show the supplier's name, address and VAT registration number, the time of supply, a description that identifies the goods or services, and — for each VAT rate that applies — the total amount payable including VAT, shown in sterling, and the VAT rate charged. Exempt supplies must not be included.

That is what a proper supermarket till receipt, petrol station receipt or stationery shop receipt looks like: the VAT number at the top, the rate against each line or in a VAT summary at the foot, and the total including VAT. If your receipt looks like that, you can reclaim the VAT on it without asking for anything else.

Worked example — the till receipt. You buy printer paper and ink for the office. The till receipt totals £120 including VAT at 20%, and it shows the shop's VAT number and the 20% rate. The VAT in the total is £120 × 1/6 = £20, so £20 goes in Box 4 and £100 is the net cost. The receipt is a simplified VAT invoice, and that is all the evidence you need. Not sure of the VAT inside a receipt total? Check it with our VAT calculator before you put it in Box 4.

The £250 limit is the line that matters. A hotel bill of £300 including VAT is over it, so a simplified invoice is not available: the VAT in the total is still £300 × 1/6 = £50, but you cannot reclaim it from a till-style receipt alone. You need a full VAT invoice, or a modified VAT invoice showing VAT-inclusive values, with your name and address on it. Ask at checkout — hotels issue them routinely, and asking later is slower once the stay is closed off.

When a receipt is NOT enough

A receipt fails as VAT evidence whenever it is missing the VAT fields. The common cases:

• A card-machine slip, bank statement or payment confirmation email. These prove payment, not VAT. A bank statement shows a payee and an amount, never a VAT number or a rate, and a "thank you, your payment of £600 has been received" email is a receipt, not a VAT invoice — unless it also carries the supplier's VAT number, the rate and the VAT amount.
• A receipt from a business that is not VAT-registered. A sole trader under the £90,000 registration threshold charges no VAT, so there is no VAT to reclaim — and a receipt from them cannot show a VAT number that does not exist. If a receipt does show a VAT number, check it: our guide to checking a VAT number explains how to verify one on GOV.UK.
• A receipt for a supply over £250. The simplified-invoice route closes at £250 including VAT, so a receipt alone cannot carry a claim above that figure.
• A pro forma invoice. This one catches people out regularly, and it has its own section below.

If you have reclaimed VAT on a document that turns out not to be a valid VAT invoice, correct it: net errors of £10,000 or less can be adjusted on your next return, and larger errors must be disclosed to HMRC separately — our correcting VAT errors guide explains the bands.

Pro forma invoices: not VAT invoices at all

A pro forma invoice looks like an invoice, carries prices and a total, and is often sent before the goods are delivered or the work is done — to get approval, release a budget or request a deposit. It is not a VAT invoice, and HMRC does not accept it as evidence for input tax: pro forma invoices are "not, therefore, acceptable evidence", and a pro forma should be clearly described as such, preferably endorsed "This is not a VAT invoice".

If you receive a pro forma, you can pay against it, but the VAT cannot go on your return until the supplier sends a proper VAT invoice. If you issue one, the obligation is yours: once payment arrives or the supply is made, you must issue a full VAT invoice — normally within 30 days — and the pro forma does not discharge that duty. Do not post a pro forma into your accounts as a sale: it is a preview, not a supply, and booking it early reports revenue and VAT liability before they are due.

The 30-day rule, with dates

A VAT invoice must normally be issued within 30 days of the date of supply. A receipt carries no such deadline, because it is not a VAT document — it is issued when payment happens. A late invoice is a problem for your customer, because their right to reclaim depends on holding it.

Worked example — the 30-day deadline. You deliver goods to a VAT-registered customer on Friday 13 November 2026. The 30 days run from the date of supply, so the VAT invoice must be issued by Sunday 13 December 2026. If the customer pays in advance instead — say on Tuesday 10 November 2026 — the payment itself creates the tax point, and the invoice must be issued by Thursday 10 December 2026. Either way, the clock runs from the earlier of supply and payment, not from the end of the month.

The 30-day rule is about issuing the invoice, not the tax point, which is fixed by the supply or the payment; a late invoice does not move it. Our VAT tax point guide works through the full rules, including deposits, continuous supplies and the 14-day invoice rule.

What to do if you only have a receipt

If a purchase matters for VAT and all you hold is a receipt, work through this in order. First, check the receipt for the VAT fields — supplier VAT number, VAT rate, VAT amount. If all three are there and the total is £250 or less including VAT, you already hold a simplified VAT invoice: file it and move on. Second, if the total is over £250, ask the supplier for a full VAT invoice promptly, while the transaction is fresh in their system. Third, if the supplier is not VAT-registered, there is nothing to reclaim — the whole amount is a business expense, but no VAT element exists. Fourth, if the supplier cannot or will not issue a VAT invoice, do not reclaim the VAT: claiming input tax without one is an error HMRC can disallow. Claim the net amount as an expense instead. Fifth, keep everything for six years — invoices, credit notes and receipts are all VAT records.

One more point: if you pay in cash and a VAT invoice has already been issued, you can ask for a dated receipt for the cash payment, and the supplier must give you one. Keep both together: invoice for the VAT, receipt for the payment.

Common mistakes with VAT receipts and invoices

1. Reclaiming VAT from a card-machine slip. It proves payment, not VAT. Without a VAT number and a rate, there is no claim.
2. Reclaiming VAT on a pro forma invoice. A pro forma is a quote, not a VAT invoice. Wait for the real invoice.
3. Using a till receipt for a purchase over £250. The simplified-invoice route stops at £250 including VAT. Ask for a full invoice.
4. Accepting an invoice with no VAT number, or issuing one late. Your customer cannot reclaim on a numberless invoice, and a late invoice delays their reclaim.
5. Showing VAT when you are not registered. Only VAT-registered businesses can issue VAT invoices. Under the £90,000 threshold and unregistered, your invoices must not show VAT or a VAT number.
6. Throwing the receipt away once the invoice arrives. The invoice is the VAT evidence; the receipt is the payment evidence. Together they are the audit trail. Keep both for six years.
