Input tax incurred in the making of exempt supplies is not claimable generally except if the De Minimis Rule is satisfied. The De Minimis Rule allows GST-registered businesses to claim input tax on exempt supplies.
On 10 July 2018, the Inland Revenue Authority of Singapore (IRAS) has made available a new calculator for partially exempt businesses to compute the amount of input tax claimable for each accounting period and input tax adjustment for the longer period.
This calculator is designed for only one longer period and GST group registrants may use the consolidated figures for all entries within the group for each quarter.
The calculator is for businesses that are under quarterly filing only. It is not applicable for businesses that have obtained approval to use a special/fixed input tax recovery formula.
The calculator (ver. 1) can be accessed from the IRAS website.
