Invoicing and VAT in the UK

In the UK and most of the EU there are rules on what must appear on a sales invoice if you are registered for VAT. Obviously those rules vary from one country to another, and you will need to check with your local inland revenue service, but there are some general rules that you should observe.

In the UK, VAT on sales is known as Output tax. That has always seemed an odd label to me since the tax is coming in to the business!, but the Inland Revenue see it one step further in that it will then go OUT from you to them.

It will come as no surprise then that VAT on purchases is called Input tax. If you are VAT registered, then you can reclaim that VAT, but this is where the rules come into play.


In order to claim the VAT, you will need to make sure the supplier’s invoice is valid. This is the minimum it must have:

  • Valid EU VAT Number
  • Supplier’s name and address
  • Description of goods/services
  • Tax Point (date of sale)

The above is known as a simplified VAT invoice and is only valid if the supply is £250 or less. It is up to you to check the VAT rate for the items you have bought. For example, if the goods were exempt, then even though you have the VAT number you cannot claim the VAT (because there isn’t any). If in doubt always ask for a modified or full invoice (see below).


Then there is the modified invoice. The legislation says you can issue this ‘if your customer agrees’. What they mean is, if your customer doesn’t mind an invoice that shows the total VAT for each rate rather than a complete breakdown item by item.

These are the things you need to show in addition to the simplified items above:

  • VAT inclusive total for each VAT rate
  • The total VAT for each VAT rate
  • The VAT exclusive total for each VAT rate

In other words you must show the exclusive and inclusive totals plus the VAT totals for each rate of VAT included in the transaction (eg. standard, reduced and exempt).

Full Invoice

In addition to the above, a full VAT invoice must include:

  • Customer’s name and address
  • Invoice number
  • Invoice date (if different to the Tax Point – which is the actual time of supply)
  • The unit price or rate and quantity of items supplied
  • Cash discount rate or amount
  • A total for each rate (so it is obvious how much of the invoice is zero rated for example)

The Tax Point is crucial. It is the date of the time of supply and it could be different from the Invoice Date. The reason is that the VAT must be accounted for by both customer and supplier at the same rate, and that can only happen if both are using the same date.

The rules state that if you are a retailer then you do not need to issue a VAT receipt (of any type) unless you are asked to do so by the customer. If any supplier fails to issue an invoice having been asked for one, a fine or other penalty can be issued by HMRC.
