Late Fees, Interest Rates, and Penalties for Missing GST Return Deadlines in 2026

The Cost of Non-Compliance: GST Penalties & Late Fees

Missing GST return deadlines (GSTR-1, GSTR-3B, or CMP-08) triggers automated, unavoidable statutory penalties administered by portal algorithms under Sections 47 and 50 of the CGST Act.

Statutory Late Fee Matrix (Section 47):

• For Taxpayers with Tax Liability: ₹50 per day of delay (₹25 CGST + ₹25 SGST) up to maximum statutory caps based on turnover.
• For Nil Return Filers: ₹20 per day of delay (₹10 CGST + ₹10 SGST) up to a maximum of ₹500 per return.
• Annual Return (GSTR-9) Late Fee: ₹50 to ₹200 per day depending on aggregate turnover.

Statutory Interest on Unpaid Tax (Section 50):

In addition to late fees, interest at 18% per annum is charged on the net tax liability paid in cash through electronic cash ledgers from the due date until the actual date of payment.

Severe Consequences: GSTIN Suspension & E-Way Bill Blocking

Failing to file GSTR-3B for two consecutive tax periods automatically blocks your E-Way Bill generation on the portal. Extended non-compliance for six months empowers the jurisdictional officer to initiate suo moto cancellation of your registration.
