GST Composition Scheme: Limits, Rates, Eligibility and How to Opt In (FY 2027-28)

The GST Composition Scheme lets a registered business pay a flat percentage of turnover (1%, 5% or 6%, depending on what you do) instead of the normal GST rates, file one return each quarter, and skip most invoicing and ledger work. In exchange, you give up input tax credit, cannot charge GST to customers, and must stay inside the turnover limit (₹1.5 crore for goods, ₹50 lakh for services in most states).

The scheme is a bargain for some businesses and a trap for others. This page covers who qualifies, what you pay, what changes in your day-to-day compliance, and how to file CMP-02 before the window closes.

Key takeaways

Goods traders and manufacturers pay 1% of turnover, restaurants without alcohol service pay 5%, and eligible service providers pay 6%.
Eligibility is tested on last financial year's turnover. To start FY 2027-28, file CMP-02 by 31 March 2027.
You cannot claim input tax credit, cannot collect GST from buyers, and cannot make inter-state sales.
Crossing the limit during the year ends your eligibility on that day, and you must file CMP-04 within 7 days.
Selling mainly to GST-registered businesses is the single biggest reason composition backfires.

What the GST Composition Scheme is

The scheme sits in Section 10 of the CGST Act, 2017, and the government built it for taxpayers whose compliance cost would otherwise swallow a large part of their margin. Under the normal system, you charge GST on each sale, claim credit for GST on purchases, and pay the difference after filing monthly or quarterly returns. Under composition, you pay a fixed slice of your turnover and nothing else. There is no credit calculation.

Because you pay the tax out of your own pocket rather than collecting it, your selling prices have to absorb the GST cost. That one fact explains most of the scheme's advantages and most of its drawbacks.

GST composition scheme limit

Two thresholds apply, and both look at your aggregate turnover in the preceding financial year, calculated on a PAN basis across India. All GST registrations under one PAN are counted together, and every one of them must opt in or none can.

Who you are Turnover limit (preceding FY) Legal basis
Manufacturer, trader of goods, or restaurant ₹1.5 crore Section 10(1)
Service provider (not restaurant) ₹50 lakh Section 10(2A)
Business in a notified special category state ₹75 lakh for goods State-specific notification

Commentary on the scheme puts the goods limit at ₹1.5 crore, dropping to ₹75 lakh in certain special category states. Check the notification for your own state before relying on the higher figure.

Aggregate turnover includes taxable sales, exempt sales and exports, and leaves out the GST charged and any tax you pay under reverse charge. Include every stream. A trader who also earns commission income through a second registration under the same PAN must add both.

One more rule catches people mid-year. The composition option lapses on the day your turnover for the year goes past the limit, and no grace period exists. Track your running total monthly, not at year-end.

Composition scheme tax rates

You pay the rate on your turnover in the state, split equally between CGST and SGST (or UTGST in union territories).

Business type Total rate CGST + SGST Example turnover Annual tax
Manufacturer or trader of goods 1% 0.5% + 0.5% ₹80 lakh ₹80,000
Restaurant (no alcohol service) 5% 2.5% + 2.5% ₹40 lakh ₹2,00,000
Service provider under 10(2A) 6% 3% + 3% ₹30 lakh ₹1,80,000

Older guides still mention a 2% manufacturer rate. That rate, along with the earlier blanket ban on e-commerce supplies and the 30 April GSTR-4 date, appears in superseded guidance that keeps circulating. The current manufacturer rate is 1%.

A goods dealer who also provides some services stays on the goods rate as long as the services are incidental. As I read Notification 2/2019-Central Tax, the cap is the higher of ₹5 lakh or 10% of the previous year's turnover. Confirm the wording against the notification for your case.

Tax is due on all turnover, including sales you made at a discount or gave as free samples where GST law treats them as supplies. Exempt supplies are the exception and sit outside the taxable turnover base.

Who is not eligible for the composition scheme

A turnover under the limit is necessary but not sufficient. You cannot opt in if you:

Make inter-state outward supplies of goods or services. This covers courier-dispatched orders to other states and, in practice, exports.
Supply goods not taxable under GST (petrol and liquor for human consumption are the usual examples).
Are a casual taxable person or a non-resident taxable person.
Manufacture ice cream, pan masala or tobacco products.
Supply services through an e-commerce operator. Goods suppliers have been allowed to stay in composition since 1 October 2023, but only for intra-state sales. The operator must block inter-state supplies by a composition dealer, collect tax at source and report in GSTR-8.
Have more than one registration under the same PAN and want to opt in with only some of them.
Do not meet the turnover test for the previous year.

For service businesses, the intra-state requirement is the one that most often closes the door. A consultant with one client in another state fails it.

If an officer finds you opted in without qualifying, expect the department to demand tax at regular rates and possibly a penalty. Section 10(5) and the demand provisions of Sections 73 and 74 apply. Getting eligibility right at the start costs far less than defending it later.

Composition scheme vs regular scheme

Point Composition Regular
Tax payable Fixed % of turnover Output tax less input credit
Input tax credit Not available Available
Charge GST on invoices No, issue a bill of supply Yes, tax invoice
Returns each year 4 CMP-08 + 1 GSTR-4 Monthly or quarterly GSTR-1 and 3B, plus annual return
Inter-state sales Not allowed Allowed
Turnover cap Yes None
Buyer gets ITC on your sale No Yes

Whether composition is cheaper is a question about your customers, not your rate. Consider a retailer selling packaged goods at a printed MRP. Selling prices are fixed, so the retailer keeps the whole sale value and pays 1% of it. Under the regular scheme, GST is carved out of the MRP and passed on. That is the situation composition suits best, and it is my own illustration of the mechanics, not a statistic.

Now consider a wholesaler selling to GST-registered shops. Those shops want credit on what they buy. A composition supplier cannot give it, so buyers drift to registered competitors, or demand a price cut equal to the credit they lose. For this business, the 1% rate rarely compensates.

Also factor in purchases. Under composition, GST paid on inputs becomes a pure cost. A manufacturer with heavy input purchases from registered suppliers should model both routes before deciding.

Compliance rules once you are in

Composition changes how you bill and what you display, not just what you pay.

Bill of supply, not tax invoice. Charge no GST on it.
Mandatory wording. Each bill of supply should carry the words "composition taxable person, not eligible to collect tax on supplies." The same wording goes on a notice at your premises.
Reverse charge. You still pay GST at normal rates on any reverse-charge purchase.
Quarterly payment. File CMP-08 with the payment by the 18th after each quarter: 18 July, 18 October, 18 January and 18 April.
Annual return. GSTR-4 moved from 30 April to 30 June of the following financial year starting FY 2024-25 (Notification 12/2024-Central Tax). Interest runs from the quarterly date, whatever date you file the annual return.
No e-invoicing. Composition dealers are outside the e-invoice requirement.

Keep purchase bills, stock registers and a running turnover sheet. The scheme is light, but the department can still ask how you computed your limit.

CMP-02 opt-in process

You file Form GST CMP-02 to move from the regular scheme to composition.

Timing. File before the financial year starts. For FY 2027-28, the last date is 31 March 2027. Anyone who misses the window must file regular returns and pay at normal rates for the year. New registrants can elect composition on the registration application itself.

Steps on the GST portal:

1

Log in at gst.gov.in with your credentials.

2

Go to Services → Registration → Application to Opt for Composition Levy.

3

Select the financial year and choose your business category.

4

Tick the declarations on eligibility and confirm that every registration under your PAN is opting in.

5

Verify with EVC or DSC and submit. Note the ARN.

After switching:

ITC-03 reverses credit on stock and capital goods held on the day you switch. The deadline is 60 days.
CMP-03 declares the stock position. File within 90 days of the start of the scheme.
You cannot claim credit on inputs from the switch date.

Opting out: CMP-04 and ITC-01

You can leave voluntarily or because you lose eligibility. Either way, file CMP-04. If you are leaving because you crossed the limit or broke an eligibility rule, the deadline is 7 days from that event. After exit, you issue tax invoices and file GSTR-1 and GSTR-3B.

To claim credit on stock held at the date of exit, file ITC-01. Do it promptly, and keep your purchase invoices ready.
