Under GST laws, delay in filing returns attracts late fees and interest penalties. Keeping track of deadlines is crucial to avoiding compliance warnings and preserving input tax credits.
For GSTR-3B & GSTR-1, the late fee is Rs. 50 per day of delay (Rs. 25 CGST + Rs. 25 SGST) where tax is payable. For Nil tax returns, it is reduced to Rs. 20 per day (Rs. 10 CGST + Rs. 10 SGST).
If tax liability is not cleared on or before the due date, interest at 18% per annum is payable on the net tax liability (the tax paid by cash ledger). No interest is charged on Nil returns.
