Tax under composition vs regular scheme. The GST Composition Scheme Calculator takes annual turnover, composition rate, gst rate you would charge under the regular scheme, input tax credit available under the regular scheme and returns regular net gst minus composition tax plus tax payable under composition (from your own pocket), output gst collected under the regular scheme, net gst payable under the regular scheme. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Indian tax rules change with each Finance Act and GST Council meeting. The rates here follow the current published rules, but confirm the figures on the official portals or with a chartered accountant before filing or invoicing. Use the worked example below to check the maths against your own figures.
How the GST Composition Scheme Calculator works
Composition dealers pay a small flat rate on turnover but cannot charge GST to customers or claim input credit, so the tax comes out of their margin. The regular scheme collects tax from customers and offsets purchases, which suits B2B businesses with registered buyers.
Worked example
With the example values (annual turnover of ₹5,000,000, composition rate "1% – traders and manufacturers", gst rate you would charge under the regular scheme of 18%, input tax credit available under the regular scheme of ₹300,000), the regular net gst minus composition tax is ₹550,000.00; tax payable under composition (from your own pocket) ₹50,000.00, output gst collected under the regular scheme ₹900,000.00, net gst payable under the regular scheme ₹600,000.00. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.
Assumptions and limits: Composition is available up to ₹1.5 crore turnover (₹50 lakh for services) and not for inter-state sales or e-commerce operators.
