2. VAT invoices

Only VAT-registered businesses can issue VAT invoices and you must:

issue and keep valid invoices (these can be paper or electronic)
keep copies of all the invoices you issue even if you cancel them or produce one by mistake

You can’t reclaim VAT using an invalid invoice, pro-forma invoice, statement or delivery note.

Valid invoices

You’ll use a full VAT invoice for most transactions. You can use:

a modified invoice for retail supplies over £250
a simplified invoice for retails supplies under £250 - and for other supplies from 1 January 2013

Include the following on your invoice, depending on which type you use.

Invoice information	Full invoice	Simplified invoice	Modified invoice
Unique invoice number that follows on from the last invoice	Yes	Yes	Yes
Your business name and address	Yes	Yes	Yes
Your VAT number	Yes	Yes	Yes
Date	Yes	No	Yes
The tax point (or ‘time of supply’) if this is different from the invoice date	Yes	Yes	Yes
Customer’s name or trading name, and address	Yes	No	Yes

(1) If items are charged at different VAT rates, then show this for each.

There are different invoice rules if you use a VAT Margin Scheme or trade internationally.

If you use the Cash Accounting Scheme you have to stamp an invoice with the amount of cash paid and the date.

Usually VAT invoices must be sent within 30 days of the date of supply or the date of payment (if you’re paid in advance).

You don’t have to show all amounts on your invoices in sterling. But if there’s any VAT due you must show this in sterling.

To convert to sterling you can:

use the market selling rate at the time of supply
use the European Central Bank’s rate - from 1 January 2013
use HMRC’s period rates of exchange - the rates usually stay the same for each calendar month
apply to HMRC to use a different method to account for the VAT

There are different rules if you use the Tour Operator’s Scheme.
