Late filing
Return filing is mandatory under GST. Even if there is no transaction, you must file a Nil return.
- You cannot file a return if you don’t file previous month/quarter’s return.
- Hence, late filing of GST return will have a cascading effect leading to heavy fines and penalty.
Late fee & Interest
- Interest is 18% per annum. It has to be calculated by the tax payer on the amount of outstanding tax to be paid. Time period will be from the next day of filing to the date of payment.
- Late fee is Rs. 100 per day per Act. So it is 100 under CGST & 100 under SGST. Total will be Rs. 200/day. Maximum is Rs. 5,000. There is no late fee on IGST.
- For delayed filing of NIL returns, late fee reduced from Rs 200 per day to Rs 20 per day.
- Late fees for GSTR-3B of July, Aug and Sept waived. Any late fees paid for these months will be credited back in Electronic Cash Ledger under ‘Tax’ and can be utilized to make GST payments.
