Reduced GST interest rates provide staged relief and conditional late-fee waivers for specified tax periods under revised notifications. Notifications amend earlier reliefs by prescribing staged interest relief for specified GST tax periods: for taxpayers above Five Crore aggregate turnover an initial zero-interest window followed by a reduced interest rate until the notified cut-off after which normal interest applies; for taxpayers below Five Crore a longer zero-interest window followed by reduced interest until the end of the relief period and normal interest thereafter. The notifications also conditionally waive late fee where returns are filed by prescribed dates, with late fee otherwise payable from the original due date until filing.
