What is the Composition Scheme?

The Composition Scheme is a simplified compliance route for small taxpayers under GST. Instead of paying tax at normal rates on every invoice and filing detailed monthly returns, a composition dealer pays a fixed percentage of turnover as tax and files a simple quarterly statement (CMP-08) plus one annual return (GSTR-4). It dramatically reduces the compliance burden for small businesses.

Eligibility — Turnover Limits

Type of BusinessAggregate Turnover Limit
Traders & Manufacturers (goods)₹1.5 crore (₹75 lakh in special category states)
Service providers (separate scheme u/s 10(2A))₹50 lakh

The limit is based on aggregate turnover (PAN-India, all GSTINs) in the preceding financial year.

Manufacturers & Traders0.5%0.5%1% of turnover

Service providers (u/s 10(2A))3%3%6% of turnover

Note: traders pay 1% on the turnover of taxable supplies only, whereas manufacturers pay 1% on total turnover.

Key Restrictions on Composition Dealers

  • Cannot collect GST from customers — the tax is paid out of the dealer's own pocket.
  • Cannot claim Input Tax Credit on purchases.
  • Cannot make inter-state outward supplies (sales must be within the state).
  • Cannot supply through e-commerce operators that collect TCS.
  • Cannot supply non-taxable goods (e.g., alcohol, petrol).
  • Must issue a Bill of Supply instead of a tax invoice, and display "composition taxable person" on signboards and bills.

Who Cannot Opt for Composition?

  • Manufacturers of ice cream, pan masala, tobacco, aerated water and certain notified goods
  • Inter-state suppliers
  • Casual taxable persons and non-resident taxable persons
  • Businesses supplying through e-commerce operators liable to collect TCS

How to Opt In

A new registrant chooses composition at the time of registration (Form REG-01). An existing regular taxpayer opts in by filing Form CMP-02 before the start of the financial year. On opting in, ITC on stock held must be reversed via Form ITC-03.

Filing CMP-08 (Quarterly)

CMP-08 is a simple quarterly statement-cum-challan used to declare turnover and pay the composition tax. Due dates:

QuarterDue Date
Apr–Jun (Q1)18 July
Jul–Sep (Q2)18 October
Oct–Dec (Q3)18 January
Jan–Mar (Q4)18 April

Late filing of CMP-08 attracts interest at 18% p.a. on the tax due, plus late fee. You must pay the tax in cash via challan before filing.

Filing GSTR-4 (Annual)

GSTR-4 is the annual return for composition dealers, due by 30 June following the end of the financial year. Its key tables:

  • Table 4: Inward supplies (purchases), including those under reverse charge.
  • Table 5: Summary of self-assessed tax already paid through CMP-08 during the four quarters (auto-reconciled).
  • Table 6: Tax rate-wise outward supplies and inward supplies attracting RCM — the actual annual liability.
  • Table 7: TDS/TCS credit received.
  • Table 8: Tax payable and paid; any shortfall between Table 6 and Table 5 must be paid.

Late fee for GSTR-4 is ₹50 per day (₹25 CGST + ₹25 SGST), capped at ₹2,000 (₹500 for a nil return).
