How to use GSTR-3B Liability & Payment Calculator
Reconcile output tax, RCM and utilisable ITC by tax head, then check interest and late fees.
Inputs and definitions
Return period, output tax, reverse-charge liabilities and verified eligible available credit, separately for IGST, CGST, SGST/UTGST and cess.
Method and formula
For each head, output tax plus RCM less legally utilised ITC gives net cash tax. Reverse charge is cash-only; cess credit pays cess only, and CGST/SGST credits cannot pay each other. Reconcile existing cash-ledger balances separately from any new deposit.
Illustrative example
If output tax is ₹1,600, RCM is ₹120 and legally utilised ITC is ₹1,600, net cash tax is ₹120. Any further unused eligible credit remains carried forward; it does not pay the reverse charge.
Scope and limitations
Review the relevant period, supplied facts, official sources and any conditions beside the result.
These examples explain the method. The interactive result depends on the selected facts and period, and is not a filing or an eligibility confirmation.
