Under the expected transitional provisions, if a supply of goods or services takes place on or after 1 July 2020, any invoice issued for any consideration received before 1 July 2020 may be considered under the 5% tax bracket for the purposes of calculating the time and tax of supply for VAT, and consequently, the supply will be subject to 15% VAT.
If an invoice is issued before 1 July 2020 for a supply that is to be performed after 1 July 2020, without including the 15% VAT applicable to the goods or services being supplied under that invoice, the supplier must issue an additional invoice specifying the additional amount of (15%-5%) VAT.
