The repurchase rate (repo rate) has decreased from 6.75% to 6.50% on 19 July 2019.
As from August 2019, the ‘low or interest free loan/debt’ fringe benefit should be calculated by using the new ‘official interest rate’.
The ‘official interest rate’ as defined in section 1 of the Income Tax Act:
= repo rate + 1%
= 6.50% + 1%
= 7.50%
