Under Section 50 of CGST Act, interest on delayed payment of GST is 18% per annum on the outstanding tax amount. It is calculated on a daily basis from the due date to the actual payment date. Formula: Tax × 18% ÷ 365 × number of days.

Can late fee be waived for GSTR-3B?

The government occasionally issues amnesty schemes to waive or reduce GST late fees via notifications. However, interest u/s 50 on tax payment delay is generally not waived. Check the latest CBIC notifications for any active amnesty scheme.
