GST Composition Scheme Calculator — Section 10 Relief for Small Businesses
The composition scheme under Indian Goods and Services Tax is a simplified tax mechanism enacted under Section 10 of the CGST Act, 2017. Designed to alleviate compliance pressure on small traders, manufacturers, restaurant operators, and service providers, it replaces monthly return filings with a straightforward quarterly payment system.
Enrolled businesses pay a nominal, fixed percentage of their aggregate turnover instead of computing detailed input tax credits (ITC). Quarterly tax payments are remitted through Form CMP-08, followed by a single annual return via Form GSTR-4.
Our free online composition calculator enables taxpayers and tax consultants to instantly compute quarterly CMP-08 liabilities and confirm eligibility against statutory turnover thresholds under the composition scheme under gst.
GST Composition Scheme Limit & Eligibility Thresholds (2026)
To qualify for the gst composition scheme, a business's aggregate annual turnover in the preceding financial year must remain strictly within statutory ceiling limits:
| Business Category | Normal States | Special Category States | CGST Section |
|---|---|---|---|
| Manufacturers & Traders | ₹1.50 Crore | ₹75 Lakhs | Section 10(1) |
| Restaurants (Non-Alcoholic) | ₹1.50 Crore | ₹75 Lakhs | Section 10(1)(b) |
| Service Providers & Mixed Suppliers | ₹50 Lakhs | ₹50 Lakhs | Section 10(2A) |
The general gst composition scheme limit for goods suppliers is ₹1.50 Crore. In 8 Special Category States (Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Uttarakhand), the limit is ₹75 Lakhs. For service providers, Section 10(2A) sets a uniform ceiling of ₹50 Lakhs nationwide.
Applicable Tax Rates Under the GST Composition Scheme
Tax rates under gst composition are substantially lower than regular GST slabs, structured as follows:
Manufacturers & Traders
0.5% CGST + 0.5% SGST. Traders pay 1% on taxable turnover, while manufacturers pay on aggregate turnover.
Restaurants (Non-Alcoholic)
2.5% CGST + 2.5% SGST on total turnover for food and beverage outlets not serving liquor.
Service Providers
3% CGST + 3% SGST under Section 10(2A) for eligible service businesses up to ₹50 Lakhs turnover.
Our composition calculator automatically calculates the exact CGST and SGST bifurcation for direct entry into your CMP-08 statement.
