Following a consultation HMRC have published ‘Revenue and Customs Brief 6: Changes in accounting for VAT after prices are altered’ to explain new rules for adjustments to VAT after changes in the price of goods or services.

The prices businesses charge for goods and services can be changed and this may be occur long after VAT has been accounted for on the supply.

HMRC say some businesses are trying to use the current rules to gain a tax advantage by making VAT adjustments for reductions in price without actually refunding customers and by attempting to treat errors as price adjustments so that they may avoid the relevant time limits.

Under the new rules, from 1 September 2019:

There are also new debit and credit note requirements and provisions to avoid double accounting where a debit/credit note equivalent document has been provided by the supplier to the customer before 1 September 2019.

HMRC updated their guidance for the change in September 2019 saying "HMRC recognises that changes to systems may take time" but without stating whether they would be applying a light touch to enforcing the new rules.
