GST Composition Scheme: Complete Guide on Eligibility, Tax Rates, Compliance Forms and Business Suitability

Understanding the Core Concept

The GST composition scheme, anchored in Section 10 of the Central Goods and Services Tax Act, offers eligible small businesses an alternative to the regular GST compliance framework. Rather than navigating the full machinery of tax invoices, input tax credit reconciliation, and monthly return filings, a composition dealer operates on a fundamentally simpler model — pay a fixed percentage of turnover, file a brief quarterly statement, and submit one consolidated annual return.

This simplicity is not without a cost. The scheme is structured as a deliberate trade-off. On one side sits a low effective tax rate and minimal compliance burden; on the other sits the inability to collect GST from buyers, the loss of all input tax credit entitlements, and categorical bars against certain business activities including inter-State outward supplies and sales through e-commerce platforms that deduct tax at source.

The composition scheme genuinely suits businesses that are small, geographically contained, and operationally straightforward. It works against businesses that are growing aggressively, depend on credit chains, or conduct trade across State boundaries. Understanding precisely where a given business falls on that spectrum is the central purpose of this guide.

Eligibility Based on Turnover Thresholds

The first filter for eligibility is aggregate turnover in the preceding financial year. Crucially, the applicable limit varies depending on both the nature of the business and the State in which it is registered.

Turnover Limits at a Glance

The lower Rs. 75 lakh threshold is applicable to Uttarakhand and the notified North-Eastern States. The Rs. 50 lakh cap under Section 10(2A) covering service providers applies uniformly across the entire country regardless of State.

The Service-Supply Concession for Goods Dealers

A question that arises frequently is whether a goods dealer who occasionally renders services gets disqualified from the scheme. The answer is no, provided the service component remains within prescribed bounds. The law permits a composition dealer in goods to also supply services, so long as such services do not exceed 10% of the previous year's turnover or Rs. 5 lakh, whichever is the higher figure. Exceeding that boundary is what triggers disqualification — not the mere presence of some service activity.

How Aggregate Turnover is Computed

A frequent misunderstanding involves treating the turnover threshold as State-specific. It is not. Aggregate turnover is calculated on a PAN-wide, all-India basis, consolidating business activity across every State and Union Territory.

The components included in aggregate turnover are:

• Taxable outward supplies
• Exempt supplies
• Export supplies (whether of goods or services)
• Inter-State supplies between distinct persons registered on the same PAN

The components excluded from the calculation are:

• The GST itself (CGST, SGST, IGST, and Compensation Cess)
• Inward supplies on which tax is paid under reverse charge mechanism by the recipient

Illustrative Calculation:

Consider Mr. Sharma, a trader in Pune whose business figures for the year are as follows — taxable domestic sales of Rs. 45 lakh, exempt supplies of Rs. 18 lakh, export turnover of Rs. 22 lakh, and inter-State branch transfers of Rs. 12 lakh. His aggregate turnover for eligibility purposes works out to Rs. 45 lakh + Rs. 18 lakh + Rs. 22 lakh = Rs. 85 lakh — comfortably within the Rs. 1.5 crore ceiling applicable to traders in Maharashtra.

The All-or-Nothing Rule for Multiple Registrations

The PAN-based aggregation also drives a critical operational consequence. Where the same PAN holds registrations in more than one State, the composition option cannot be exercised selectively. Either all registrations move into composition, or all of them remain under the regular scheme. Partial or branch-level adoption is not permitted under the law.

Categories of Persons Barred from the Scheme

Irrespective of turnover, certain categories of persons are statutorily excluded from the composition scheme:
