GST Composition Scheme: Is 1% GST Worth Giving Up Input Tax Credit?
Published 30 June 2026 · GST & TDS
Priya runs a small grocery shop in Jaipur. Her annual turnover is ₹60 lakh — enough to require GST registration, but well within the ₹1.5 crore ceiling for the Composition Scheme. Her accountant told her she could either file monthly GSTR-1 and GSTR-3B under the regular scheme, or pay a flat 1% on turnover under composition. Priya had one question: which one actually costs less? The answer depends less on the tax rate and more on how much ITC her business can actually claim.
Composition vs Regular: Priya's Break-Even Calculation
Under the Composition Scheme, Priya pays 1% GST on her entire ₹60L turnover = ₹60,000 per year. She files a quarterly CMP-08 challan and an annual GSTR-4. She does not collect GST from customers and cannot claim ITC on her purchases.
Under the Regular Scheme, groceries attract 5% GST. Priya collects 5% GST on sales = ₹3,00,000 from customers. She can claim ITC on purchases from GST-registered suppliers. If 80% of her goods come from registered suppliers at 5% GST: ITC = 5% × ₹48L = ₹2,40,000. Net GST payable = ₹3,00,000 − ₹2,40,000 = ₹60,000.
Same cash outflow. But the regular scheme means monthly filing (GSTR-1 by 11th, GSTR-3B by 20th), reconciling GSTR-2B, maintaining detailed records for every invoice. The composition scheme means one quarterly payment and a simple annual return. For identical tax liability, composition wins on compliance cost and time.
When Composition Wins vs When Regular Wins
| Business Type | Turnover | ITC Available | Composition GST | Regular Net GST | Winner |
|---|---|---|---|---|---|
| Grocery (5% GST, 80% taxable inputs) | ₹60L | ₹2.4L | ₹60,000 | ₹60,000 | Tie — composition wins on compliance |
| Restaurant (5% GST, 50% inputs exempt) | ₹50L | ₹25,000 | ₹75,000 | ₹2.5L − ₹0.25L = ₹2.25L | Composition wins |
| Manufacturer (18% GST, high inputs) | ₹1Cr | ₹10L | ₹2L (at 2%) | ₹18L − ₹10L = ₹8L | Composition wins on cash — but check customer ITC needs |
For the restaurant example, the minimal ITC (just 50% of inputs are GST-taxable) means the regular scheme yields very little credit. The regular scheme GST liability of ₹2.25L is nearly three times the composition tax of ₹75,000. Composition is the clear winner — unless the restaurant's customers are primarily corporate accounts needing GST invoices.
The Customer ITC Problem: Why B2B Businesses Cannot Use Composition
Here is the constraint that eliminates composition for many businesses: a composition taxpayer cannot issue a tax invoice. They issue a "Bill of Supply" instead. Their customers — if GST registered — cannot claim ITC on purchases from a composition taxpayer.
If Priya's grocery shop primarily sells to consumers (individuals buying vegetables and staples for home), this does not matter. Consumers cannot claim ITC regardless. But if Priya starts selling bulk supplies to restaurants, caterers, or other businesses who want to claim ITC on their purchases, those customers will prefer to buy from regular GST taxpayers. Priya's composition status makes her less attractive as a supplier to businesses.
This is why composition is primarily viable for B2C (consumer-facing) businesses: retail shops, small restaurants, neighbourhood services. Wholesalers, distributors, manufacturers whose customers are businesses — composition cuts off a critical part of their commercial offering.
Eligibility: Who Can and Cannot Use Composition
Composition is available for businesses with aggregate annual turnover up to ₹1.5 crore (₹75 lakh for special category states including Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, Uttarakhand, Himachal Pradesh, and J&K).
Not eligible: businesses that supply goods across state lines (inter-state supply), sellers on e-commerce platforms (Amazon, Flipkart, etc.), manufacturers of notified goods (tobacco, pan masala, ice cream), service providers (except restaurants up to ₹50L turnover), and anyone who is part of a GST group where any member is ineligible.

Compare Composition vs Regular Scheme →What Most Business Owners Get Wrong About the Composition Scheme
The most common misconception: composition always means less tax. As the grocery example shows, that is only true when your ITC eligibility is low. A manufacturer buying heavily from registered suppliers at 18% GST might find the regular scheme yields a lower net tax than the 2% composition rate on high turnover.
The second misconception: that composition is permanent. You can voluntarily switch to the regular scheme mid-year if your business crosses the turnover limit or if you want to serve B2B customers. You must intimate the tax authority using Form GST CMP-04. Once you opt out of composition, you cannot re-enter in the same financial year.
Composition is correctly understood as a compliance simplification tool, not a tax minimisation tool. The real benefit is fewer filings, no GSTR-2B reconciliation, and quarterly (not monthly) payment. For a small business owner who spends 2–3 hours a month on GST compliance, composition might save more in accountant fees than in actual tax.
Frequently Asked Questions
What is the GST Composition Scheme?
A simplified GST scheme for small businesses with turnover up to ₹1.5 crore (₹75L for special category states). Instead of tracking ITC and paying 5/12/18/28% GST on each transaction, composition taxpayers pay a flat rate: 1% for traders, 2% for manufacturers, 5% for restaurants. But they cannot collect GST from customers or claim ITC on purchases.
Who is eligible for the GST Composition Scheme?
Businesses with aggregate annual turnover up to ₹1.5 crore (₹75L for J&K, Himachal Pradesh, Uttarakhand, Manipur, Mizoram, Tripura, Nagaland, Arunachal Pradesh, Meghalaya, Sikkim). Not eligible: inter-state suppliers, e-commerce sellers, service providers (except restaurants up to ₹50L), and those supplying non-taxable goods.
What are the disadvantages of the Composition Scheme?
Cannot collect GST from customers (the tax is from your own pocket). Cannot claim Input Tax Credit. Cannot sell outside your state. Cannot supply exempted goods that are separately tracked. Must display "Composition Taxable Person" on invoices. File quarterly returns (CMP-08) instead of monthly GSTR-1/3B.
When is the Composition Scheme financially better?
When your ITC eligibility is small relative to your turnover. Example: a retailer buying tax-exempt goods or buying from unregistered suppliers gets minimal ITC. Their effective tax under regular scheme may be higher than 1% on turnover. For high-ITC businesses (manufacturers with significant raw material GST), regular scheme usually wins.
Can a service provider opt for the Composition Scheme?
Limited. Service providers (excluding restaurants) cannot opt for the regular Composition Scheme. They can opt for the CGST Rules 7 composition for service providers (up to ₹50L turnover) at 6% GST — 3% CGST + 3% SGST. This was introduced to include service businesses in simplified compliance, but with a higher rate than goods composition.
Are your customers primarily consumers (B2C) or businesses who need GST invoices for their own ITC claims — because the answer determines whether the composition scheme is viable for you?
