GST Composition Scheme 2026: A Complete Guide for Small Businesses

Running a small business in India often means navigating GST compliance designed for enterprises ten times your size. The composition scheme simplifies taxation by offering lower rates and minimal filing requirements for eligible businesses.

But the scheme carries restrictions that many business owners overlook before opting in. And opting in without understanding those restrictions can cost more than it saves.

This guide covers exactly who can opt into the GST composition scheme, what tax rates apply, how CMP-08 and GSTR-4 filings work, and where the scheme’s limitations matter most, including how lenders read composition status when evaluating business creditworthiness.

What Is the GST Composition Scheme?

The GST composition scheme is an alternative tax compliance mechanism under Section 10 of the CGST Act, 2017. It allows eligible small businesses to pay GST at a fixed, lower rate on their turnover instead of calculating tax invoice by invoice on every transaction.

To understand how regular GST registration differs from composition in terms of obligations and eligibility, our registration guide covers the full process. Under the regular GST framework, a business must maintain detailed records of every purchase and sale, reconcile input tax credit, and file monthly returns. For a business doing ₹30–40 lakh in annual turnover, that level of compliance infrastructure is disproportionate.

The composition scheme addresses this by replacing the full compliance cycle with a flat turnover-based tax and two simplified filings per year. The tradeoff is significant: composition dealers cannot collect GST from customers, cannot claim input tax credit, and cannot make inter-state supplies.

Understanding these tradeoffs is as important as understanding the benefits.

Who Can Opt Into the Composition Scheme?

The GST Council has revised eligibility primarily based on annual turnover thresholds since 2017.

For manufacturers and traders: Businesses with an aggregate annual turnover of up to ₹1.5 crore in the preceding financial year can opt into the composition scheme. Whereas, for businesses in Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Uttarakhand, the threshold is ₹75 lakh.

For service providers: A separate composition-like scheme, often called the CGST Rule 7 or “composition for service providers”, allows businesses supplying services (other than restaurant services) with turnover up to ₹50 lakh to pay tax at 6% (3% CGST + 3% SGST) on total turnover. Notification No. 2/2019-CT(R) introduced this as a separate provision from Section 10, though commonly grouped under composition.

For restaurant services: Restaurants not serving alcohol can opt under Section 10(1)(b) and pay at 5% on turnover.

The turnover limit is aggregate, meaning it covers all registered businesses under the same PAN across India, not just one registration.

Who Is Excluded from the Composition Scheme?

Several categories of businesses cannot opt in regardless of their turnover:

• Businesses engaged in the supply of services (other than restaurant services and the Rule 7 scheme) cannot use the Section 10 composition route
• Businesses making any inter-state outward supply of goods are ineligible
• Businesses supplying goods through e-commerce operators liable for TCS under Section 52 cannot opt in.
• Exclude manufacturers of notified goods such as ice cream, pan masala, tobacco products, and aerated beverages.
• Casual taxable persons and non-resident taxable persons cannot opt in
• Businesses with any registration in states outside their principal place of business that do not also opt for composition cannot selectively apply the scheme to one registration

If any of these conditions apply, the business must operate under the regular GST framework regardless of turnover.

Tax Rates Under the Composition Scheme

One of the scheme’s central advantages is its rate simplicity. Rather than applying different rates to different goods or services, composition dealers pay a uniform rate on their total turnover.

**Category**	**Total Rate**	**CGST**	**SGST**
Manufacturers (other than notified goods)	1%	0.5%	0.5%
Traders (dealers in goods)	1%	0.5%	0.5%
Restaurant services (not serving alcohol)	5%	2.5%	2.5%
Service providers (Rule 7 scheme)	6%	3%	3%

These rates apply to turnover, not to value-added. This is a key distinction. A regular GST dealer pays tax only on the margin (after offsetting input tax credit). A composition dealer pays on the full turnover, even if margins are thin.

To appreciate how the flat composition rate versus standard GST slabs compares, where rates range from 1% to 28% depending on the product category, our full rate guide provides the complete slab-wise breakdown. For a trader buying goods at ₹90 and selling at ₹100, the effective regular GST burden might be ₹1.80 (18% of ₹10 margin).

For a trader buying goods at ₹90 and selling at ₹100, the effective regular GST burden might be ₹1.80 (18% of ₹10 margin). The composition tax would be ₹1 (1% of ₹100 turnover). On paper, composition appears cheaper, and often is for high-margin businesses. For low-margin businesses, the calculation may tip the other way.

The tax paid under the composition scheme is borne entirely by the dealer. Do not charge or show GST on invoices to customers.

Compliance Obligations: CMP-08 and GSTR-4

The compliance reduction under the scheme is real. Where regular taxpayers file monthly GSTR-1 and GSTR-3B returns, composition taxpayers file CMP-08 instead of the regular GSTR-3B, a quarterly self-declaration with no invoice-level detail required. Composition dealers are required to file just two types of returns:

CMP-08: Quarterly Tax Payment Statement

CMP-08 replaced the earlier GSTR-4 quarterly return. It is a self-declaration of tax payable for each quarter, filed by the 18th of the month following the end of each quarter.

• Q1 (April–June): Due by 18 July
• Q2 (July–September): Due by 18 October
• Q3 (October–December): Due by 18 January
• Q4 (January–March): Due by 18 April

CMP-08 does not require itemised invoice details. The dealer simply declares the total turnover for the quarter and calculates tax accordingly. Payment must be made at the time of filing.

GSTR-4: Annual Return

GSTR-4 is an annual return consolidating the full year’s turnover and tax payments. Composition taxpayers file GSTR-4 in place of GSTR-9; our guide on the annual GSTR-4 that composition taxpayers must file also provides useful context on what the regular GSTR-9 requires, especially if you transition out of the composition scheme. It is due by 30 April of the financial year following the year of composition. So for FY 2024–25, GSTR-4 must be filed by 30 April 2025.

GSTR-4 auto-populates data from CMP-08 submissions and inward supply data from GSTR-2B (for purchases from regular dealers). The dealer must verify and supplement as needed.

Composition dealers need not maintain detailed purchase registers for ITC, as they cannot claim ITC. However, they must maintain records of goods manufactured, traded, or services supplied, along with stock registers.

How to Opt In and Opt Out

Opting In

A new business registered under GST can opt for composition at the time of registration by selecting the relevant option. Existing registered businesses can opt in at the beginning of any financial year by filing Form CMP-02 before 31 March of the preceding year on the GST portal (gst.gov.in).

On opting in, the business must also file Form ITC-03 to reverse any input tax credit already accumulated on stock held on the date of transition.

Opting Out

A composition dealer must exit the scheme if:

• Turnover crosses the applicable threshold during the year
• The business begins making inter-state supplies
• The business starts dealing in excluded categories of goods or services
• The business voluntarily wishes to switch to regular GST

On crossing the threshold, the dealer must file Form CMP-04 within seven days. Once you cross the threshold, operate as a regular taxpayer, issue full invoices, collect GST, and file monthly returns.

Any business that exceeds the threshold and does not switch in time is liable to pay the differential tax (as if it were a regular dealer from the date of crossing), plus interest and penalties.

Composition Scheme vs Regular GST: A Direct Comparison

**Parameter**	**Composition Scheme**	**Regular GST**
Annual turnover eligibility	Up to ₹1.5 crore (goods)	No upper limit
Tax rate	1–6% on turnover	5–28% on value-added
Input tax credit	Not available	Available
Inter-state supply	Not permitted	Permitted
E-commerce supply	Not permitted	Permitted
GST is charged on the invoice	Not permitted	Mandatory
Returns filed per year	CMP-08 (4) + GSTR-4 (1)	GSTR-1 + GSTR-3B (monthly/quarterly)
Compliance burden	Low	Moderate to high
Suitable for	Low-margin, local, B2C businesses	Businesses with high ITC or B2B customers

The right choice depends heavily on the business model. A local kirana store serving end consumers with no inter-state ambitions is a strong composition candidate. A manufacturer selling to other businesses, who need to claim ITC from their purchases, is not, because buyers cannot claim ITC from a composition dealer’s invoice.

Limitations That Every Business Must Understand

The scheme’s restrictions go beyond what the headline rates communicate.

No input tax credit on purchases. Every purchase a composition dealer makes from a regular GST dealer carries embedded tax that the composition dealer cannot recover. Over a year, this becomes a meaningful cost, particularly for businesses with high purchase volumes relative to turnover.

No GST collection from customers. The tax is an out-of-pocket cost for the dealer. This is structurally fine for B2C businesses, but it creates problems when selling to GST-registered businesses, who cannot claim input credit from a composition dealer. This effectively makes composition dealers less attractive suppliers for B2B buyers, which can limit market reach.

No inter-state sales. Growth often requires selling to customers in other states. The composition scheme prohibits this entirely. Any inter-state outward supply forces an immediate exit from the scheme.

No e-commerce operator-based sales. Selling through platforms like Amazon, Flipkart, or Meesho, where TCS provisions under Section 52 apply, is prohibited. This excludes composition dealers from a significant and growing sales channel.

Loss of composition status is retroactive in some cases.If a business violates composition conditions, authorities apply tax, interest, and penalties from the violation date, not discovery.

What Composition Status Tells a Lender

For lenders using GST data in credit evaluation, particularly in working capital and supply chain finance, a borrower’s composition registration provides specific signals.

Revenue ceiling: A composition dealer’s turnover is capped below ₹1.5 crore by definition. This is useful for loan sizing, but it also means GST filings provide a cleaner, low-fraud revenue picture than a regular dealer’s returns (since composition dealers cannot inflate ITC claims or manipulate sales/purchase mismatches).

Business model constraints: Interstate sales prohibition and e-commerce restrictions indicate the business is local or hyperlocal. This affects the addressable market, growth ceiling, and collateral risk.

Compliance pattern: CMP-08 filing regularity, whether the dealer files on time each quarter, is a meaningful proxy for operational discipline. A business with consistent on-time CMP-08 filings over 8–12 quarters demonstrates basic financial management even without audited statements.

Transition events: A dealer who recently crossed the composition threshold and switched to regular GST suggests a growth event. This is a positive signal, but it also means the lender must reassess the full compliance history under the new regime before extending credit.

Fineye’s GST intelligence layer reads composition registration status, filing history, and threshold transitions automatically, allowing lenders to calibrate credit parameters without manual GST portal lookups for each applicant.

Key Takeaways

• The GST composition scheme allows eligible small businesses to pay a flat 1–6% tax on turnover, replacing complex monthly returns with quarterly CMP-08 payments and one annual GSTR-4 return.
• Limit eligibility to businesses with turnover up to ₹1.5 crore (goods) or ₹50 lakh (services). Exclude inter-state suppliers, e-commerce sellers, and dealers in notified goods.
• Composition dealers cannot collect GST from customers, cannot claim input tax credit, and cannot make inter-state outward supplies- three restrictions that can significantly limit business scalability.
• The scheme is most appropriate for low-margin, B2C, locally-operating businesses; B2B sellers and growth-stage businesses typically benefit more from the regular GST framework.
• Exceeding the turnover threshold mid-year requires immediate exit from the scheme and retrospective regular GST compliance from the date of crossing.
• For lenders, composition status is a reliable indicator of business scale, model type, and compliance discipline, and transitions out of the scheme signal growth events worth examining closely.

Frequently Asked Questions

Conclusion

The GST composition scheme delivers what it promises: simpler compliance and lower direct tax outgo for eligible small businesses. But its value depends entirely on the business model it is applied to.

For a kirana store, a local manufacturer, or a small restaurant, the scheme eliminates compliance overload and reduces the need for a dedicated accountant. For a business with B2B buyers, interstate ambitions, or plans to sell through e-commerce platforms, the restrictions are structurally incompatible with growth.

The decision to opt in should be made with a full understanding of both the savings and the ceiling it imposes. And the decision to exit, when turnover grows or when buyers start demanding ITC-eligible invoices, should happen proactively, not reactively.

As GST compliance data becomes a standard input in lending and due diligence, the composition scheme’s clean filing structure and predictable tax pattern make it unexpectedly useful, not just as a compliance mechanism, but as a credibility signal for small businesses seeking formal credit access. Bookmark the full GST compliance calendar for all compliance due dates applicable to composition taxpayers, including CMP-08 quarterly deadlines and the GSTR-4 annual filing date, so no deadline catches you off guard.
