The standard rate of VAT was temporarily reduced to 15 per cent on 1 December 2008 and it will return to 17.5 per cent on 1 January 2010.
For any sales of standard-rated goods or services that you make on or after 1 January 2010 you must charge VAT at the rate of 17.5 per cent. If you have a cash business and calculate your VAT using the VAT fraction you must revert to the VAT fraction of seven fortysevenths from 1 January 2010.
The change only applies to the standard VAT rate. There are no changes to sales that are zero-rated or reduced-rated for VAT.
