Formulas for 40% GST
Under GST 2.0 rules: - Exclusive (Add Tax): GST = (Base × 40) / 100. Total = Base + GST. Example: ₹10,000 base + ₹4,000 GST = ₹14,000. - Inclusive (Remove Tax): Base = Total / (1 + 0.40) = Total / 1.40. GST = Total - Base. Example: ₹10,000 gross = ₹7,142.86 base + ₹2,857.14 GST. - Split: 40% intra-state GST splits into 20% CGST and 20% SGST. Inter-state transactions apply 40% IGST.
