GST Delay payment interest order due date

For GST delay payment of interest, due dates vary based on the type of taxpayer and return forms. Here are some key due dates to keep in mind: - *GSTR-1 (Monthly)*: 11th of the next month - *GSTR-1 (Quarterly)*: 13th of the month succeeding the quarter - *GSTR-3B (Monthly)*: 20th of the next month - *GSTR-3B (Quarterly)*: 22nd or 24th of the month succeeding the quarter - *GSTR-4 (Annual)*: 30th of June succeeding the financial year (for FY 2024-25) - *GSTR-9 (Annual)*: 31st December of the next financial year Interest is applicable on late payment of GST liability, calculated on the net tax liability after reducing the input tax credit claims. The interest rate is 18% per annum, and it's essential to pay the interest to avoid further penalties.

 Interest under Section 50 of the CGST Act applies at 18 percent per annum for delayed payment of any tax liability. Interest is calculated from the day after the due date until the actual date of payment, on the tax amount remaining unpaid.

For GSTR-3B: If you file and pay by June 20, 2026 for May 2026, no interest applies. If you pay late, interest at 18 percent per annum is computed on a daily basis. On a tax liability of Rs 1 lakh, each day of delay costs approximately Rs 49 in interest.

Late fee additionally applies at Rs 50 per day under Section 47, up to a maximum of Rs 10,000 for nil returns and 0.25 percent of turnover for others.

For demand orders under Section 73 or 74: The period for the department to issue a demand notice is 3 years from the due date of the annual return for the relevant year in non-fraud cases, and 5 years in fraud cases. Interest accrues from the original due date of the return, not from the date of the demand order.
