We raised some sales invoices in November 2008 with VAT charged at 17.5%, for services to be delivered in December 2008. The invoices have already been paid. Do we have to take any action now because of the decrease in the standard VAT rate to 15% from 1 December 2008?
You don’t have to make any adjustments to your invoices if you don’t want to, as the VAT was correctly accounted for in November. However, you may issue a credit note if you wish to amend the original invoices to show services supplied in December at 15% VAT. This will only be worthwhile where your customers are unable to reclaim the full amount of the VAT charged.
