GST Late Fee & Interest Calculator
Late fee (₹/day capped) plus 18% annual interest on delayed GST payment — the cost of missing a return deadline.
Formula
Two penalties stack: a per-day late fee (CGST + SGST, so the real per-day is double the single component, capped) plus 18% annual interest on the net cash tax delayed. Interest runs on the tax paid by cash ledger, not the ITC-set-off portion. File nil returns on time too — the ₹20/day fee still accrues.
Caps and amnesty schemes change — verify the current notification. Not financial advice — for informational and analytical use only. Verify all figures with a qualified professional before acting on them.
