What is the late fee for GSTR 3B?

As per Section 47 of the CGST Act, late fees are a daily penalty levied for filing GST returns late. Only cash is allowed for payment of the late fee. Taxpayers are unable to use the Input Tax Credit, or ITC, which is available in the electronic credit ledger, as a method of paying for GST late fees.

Even though there are no sales or purchases and no GST liabilities to disclose in the GSTR-3B, the late fee is still charged if nil returns are filed late.

Late fees for GSTR-3B can be paid in the subsequent month. You cannot file the current month’s return before paying the previous month’s late fees.
