VAT: Credit notes – what are they and how are they treated?

By   18 April 2023

VAT Basics

There can be confusion about credit notes and how they are used and accounted for, so I thought it worthwhile to pull together, in one place, an overview of the subject.

What are credit notes for?

A VAT credit note is a document issued by a supplier to a customer. It amends or corrects a previously issued invoice. Invoices are documents which evidence a taxable supply. The credit note is documentary evidence of a change to that supply, or of a decrease in the consideration for that supply. A reduction in consideration may be as a result of; cancellation, discount, refund, prompt payment, bulk order or other commercial reasons.

Why are VAT credit notes important?

The information given on a credit note is the basis for establishing the adjusted VAT figure on the supply of taxable goods or services. It also enables the customer to adjust the figures for the total VAT charged to them on their purchases.

If a business issues a credit note showing a lesser amount of VAT than is correct, it is liable for the deficiency.

Legislation

The UK Law that covers credit notes is found in VAT Regulations 1995, Regulations 15, 24 and 38 of. Regulation 24A defines the term “increase (or decrease) in consideration”.

Conditions of a valid credit note

Requirements for a credit note to be considered valid:

  • be issued to the customer
  • correct a genuine mistake or overcharge
  • reflect an agreed reduction in the value of a supply
  • give value to the customer
  • not be issued for a bad debt
  • be issued in good faith

HMRC also require for credit notes to:

  • be issued within 14 days of the decrease in consideration
  • contain all the details specified in Notice 700, Paragraph 18.2.2.

Accounting

HMRC has issued guidance on how to correct VAT errors and make adjustments or claims – VAT Notice 700/45.

When you issue a credit note you must adjust:

  • the records of the taxable supplies you have made
  • your output tax

The accounts or supporting documents must make clear the nature of the adjustment and the reason for it.

Where the adjustment is not in respect of an error in the amount of VAT declared on a VAT return, you should make any VAT adjustment arising from the issue or receipt of a credit or debit note in the VAT account in the accounting period in which the decrease in price occurs.

This will be the accounting period where the refunded amount is paid to the customer.

If you have charged an incorrect amount of VAT and have already declared it on a VAT return you can only correct an error in your declaration by adopting the appropriate method of error correction procedures.

Specific cases

Credits and contingent discounts

When a business allows a credit or contingent discount to a customer who can reclaim all the tax on the relevant supply, it does not have to adjust the original VAT charge – provided both it and its customer agree not to do so. Otherwise, both parties should both adjust the original VAT charge. A business should issue a credit note to its customer and keep a copy.

Prompt payment discounts

If the discount is taken up within the specified time you may adjust the consideration and amount of VAT accounted for by issuing a credit note. If you choose not to use a credit note, the original invoice must have the following information:

  • the discount terms (which must include, but need not be limited to, the time by which the discounted price must be paid)
  • a statement that the customer can only recover as input tax the VAT paid to the supplier

VAT rate change

Where a VAT invoice showed VAT at the old higher rate, then a credit note should be issued for the element of overcharged VAT. However, there is no way to charge VAT at the lower rate if:

  • VAT invoices for supplies were issued before the lower rate took effect, and
  • the supplies were actually made (delivered or performed) before then.

In such circumstances, VAT cannot be saved by issuing a credit note for the old VAT invoice and then issuing a new invoice charging VAT at the lower rate.

The deadline for issuing a credit note following a rate change is 45 days. Any credit notes issued after this 45-day deadline are invalid, so the old higher rate would apply to the affected supplies.

Case law – further reading

There is a significant amount of case law on credit notes as this is an area that often creates disputes. Some of the most salient cases are:

  • British United Shoe Machinery Company Ltd (1977 VATTR p187)
  • Silvermere Golf and Equestrian Centre Ltd (1981 VATTR p 106)
  • Robin Seamon Brindley Macro (MAN/83/100)
  • Highsize Ltd (LON 90/945)
  • Kwik Fit (GB) Ltd (1992 VATTR p427)
  • British Telecommunications plc (LON/95/3145)
  • The Robinson Group of Companies Ltd (MAN/97/348)
  • General Motors Acceptance Corporation UK Ltd (GMAC)(LON/01/242)

NB: A business can only reduce the output VAT on its return if it has made an actual refund. This could be by making a payment to the customer or offsetting the credit against other invoices.

Finally

Failing to issue a credit note is a mistake that needs to be corrected under the error correction procedures.
