Are you registered for VAT? If so, it might be a good time to review the format of your VAT invoices. VAT invoice requirements are highly specific. If you don’t put the right information on VAT invoices, it can scupper your attempts to claim for VAT input tax.

This is a lesson learned by one firm. According to, HMRC disallowed a claim for £14,667. The reason? The invoice didn’t include ‘a description sufficient to identify the goods or services supplied’.

Issuing VAT invoices 

It may be obvious, but only VAT registered businesses can issue VAT invoices. If you are thinking of registering for VAT, you can find more information here. Remember, if your VAT taxable turnover is over £90,000 you must register for VAT. If you have any queries about what constitutes VAT taxable turnover, please speak to your THP account manager.

When you issue VAT invoices, you must:

  • Issue either paper or electronic invoices – and keep copies
  • Keep copies of invoices you cancel or produce in error
  • Keep all invoices for items you buy.

So far, so good. But are there VAT invoice requirements you need to follow?

Current VAT invoice requirements 

Depending on the transaction, you can issue one of three types of VAT invoice: a full invoice, a simplified invoice or a modified invoice.

A full VAT invoice is the most detailed and is what you’ll issue in most situations. However, you can issue a simplified invoice for supplies under £250 (including VAT). If your customer agrees, you can issue a modified invoice with VAT inclusive values rather than VAT exclusive amounts. These are for supplies over £250.

So what information needs to go on the three different types of VAT invoice? You can read chapter and verse in the Value Added Tax Regulations 1995 (available here). HMRC also publishes a much simpler table, which we’ve reproduced below.

Worth bearing in mind…

HMRC not only stresses that you can’t reclaim VAT with an invalid invoice, but also that you can’t reclaim it with a pro-forma invoice, statement or delivery note. Also, if you use the Cash Accounting Scheme, you must stamp invoices with the date and the amount of cash paid. There are also different record keeping rules for the VAT Margin Scheme.
