Add or extract GST with CGST/SGST or IGST breakdown.
Enter amount and your applicable GST rate. Choose tax-inclusive/exclusive and CGST plus SGST/UTGST or IGST, then review and export CSV.
An exclusive 1,000 amount at a user-entered 18% gives 180 tax and 1,180 total; the intra-state split is 90 plus 90.
Rates are user inputs, not current product classifications. Verify place of supply and applicable rules. Excludes exemptions, cess, reverse charge and registration validation. Half-up currency rounding; split shares reconcile to total tax.
