Composition Scheme vs Regular GST: Side-by-Side Comparison

Introduction

You have just crossed ₹40 lakh in sales as a trader, or ₹20 lakh if you sell services. Now you must register for GST. But the government gives you a choice: the composition scheme or regular GST. Which one saves you money? Which one lets you do what you want? This article answers that question. We will walk through both schemes side by side so you can see exactly what each one means for your shop, your paperwork, and your pocket.

Regular GST vs Composition Scheme: What Is the Real Difference?

Think of regular GST and composition scheme as two different contracts with the tax department. With regular GST, you collect tax from your customers, file detailed returns every month, and claim back the tax you paid on your purchases (called input tax credit or ITC). With the composition scheme, you pay a flat rate on your sales, skip detailed returns, and you do not get to claim back any tax you paid. That is the core trade-off.

Let us say you own a kirana shop. Under regular GST, if a customer buys ₹100 of biscuits from you, you add the GST tax rate (usually 5%) and charge ₹105. You keep the ₹5, and later file a form saying you collected it. But you also paid tax when you bought those biscuits from your wholesaler. The government lets you subtract that tax from the ₹5 you collected. So you might owe only ₹2 after the deduction. This is ITC—a refund or credit for tax you already paid up the chain.

Under the composition scheme, you do not do any of this. You pay a flat rate (say, 1% for traders) on your ₹100 of biscuits sales each month. So you owe ₹1. No detailed return, no claiming back tax you paid on wholesale purchases, no ITC. Simpler, but you lose the refund benefit.

The composition scheme has a turnover cap: ₹1.5 crore per year. If you exceed that, you must switch to regular GST. Also, certain kinds of businesses cannot use composition at all—for example, e-commerce platforms, restaurants that serve alcohol, and importers. And if you use composition, you cannot make supplies across state lines (inter-state supplies of goods), and you cannot issue invoices that claim ITC to your customers.

With regular GST, there is no turnover cap (as long as you cross the registration threshold). You can supply goods and services anywhere in India, and if your customer is GST-registered, they can claim ITC on your invoice. You file two forms every month: GSTR-1 (what you sold) and GSTR-3B (what you owe), plus a detailed annual return.

When Composition Saves You Money (and When It Does Not)

Composition is usually cheaper if your business has high expenses and low profit margin. Imagine a small textile manufacturer. She buys raw cloth for ₹100,000, pays GST (say 5%), adding ₹5,000 to her cost. She sells finished cloth for ₹120,000. Under regular GST at 5%, she collects ₹6,000 tax from customers. She deducts the ₹5,000 she paid on purchases, so she owes the government ₹1,000. Her actual tax rate on profit is quite low.

Under composition at 1%, she pays flat 1% on ₹120,000 = ₹1,200. Close to regular, but the calculation is simpler.

Now imagine a consultant earning ₹50,000 a month and has almost no business expenses. Under regular GST at 18%, she collects ₹9,000 from clients. She has no purchases to claim ITC against (or very little), so she owes close to the full ₹9,000. Under composition at 6% (the rate for eligible services), she pays ₹3,000. Much lower. Composition wins.

But here is the catch: you cannot grow past ₹1.5 crore turnover in composition. If your kirana shop does ₹1.6 crore sales next year, you must switch to regular GST immediately. You cannot claim ITC for the previous year either—you lose it. For businesses planning to scale, regular GST might be safer from the start, even if it costs more today.

A Simple Example

Meet Ramesh, a stationery shop owner. His turnover last year was ₹50 lakh—well under the ₹1.5 crore composition cap. He buys stock worth ₹30 lakh and sells it for ₹50 lakh. His profit is ₹20 lakh before tax.

Under Regular GST (5% rate for most stationery):

• Monthly sales: ₹4.17 lakh
• Tax collected from customers: 5% of ₹4.17 lakh = ₹20,850 per month
• Monthly purchases: ₹2.5 lakh
• Tax paid on purchases: 5% of ₹2.5 lakh = ₹12,500 per month
• Tax owed to government: ₹20,850 − ₹12,500 = ₹8,350 per month
• Annual tax to government: ₹8,350 × 12 = ₹1,00,200

Under Composition Scheme (1% rate for traders):

• Monthly sales: ₹4.17 lakh
• Flat tax due: 1% of ₹4.17 lakh = ₹4,170 per month
• Annual tax to government: ₹4,170 × 12 = ₹50,040
• No ITC claim, no detailed return filing

Ramesh saves ₹50,160 in tax by choosing composition. Plus, he files one simple return per quarter instead of monthly detailed forms. His paperwork drops from hours to minutes. The trade-off: if he wants to supply goods to another state, or if his turnover creeps past ₹1.5 crore, he must switch out and cannot claim back years of tax already paid.

Who This Applies To

Choose composition if:

• Your turnover is between the registration threshold (₹40 lakh for goods, ₹20 lakh for services) and ₹1.5 crore
• You make mostly intra-state (same-state) supplies
• Your customers are retail shoppers or small traders, not large GST-registered businesses
• You have high business expenses but want simpler compliance
• You want to avoid filing detailed monthly returns

Stick with regular GST if:

• You plan to grow beyond ₹1.5 crore in the next few years
• You supply to other states (inter-state sales of goods)
• Your customers are large businesses that need to claim ITC on your invoices
• You run a restaurant with alcohol, an e-commerce platform, or an import business
• You have very low business expenses and keep most of your sales as profit

Check Your GST Position

Before you decide, check: did your annual turnover cross ₹40 lakh (for goods) or ₹20 lakh (for services)? If you are in a special category state, the limit is ₹10 lakh for both.

Once you know where you stand, read the composition scheme eligibility guide or speak to a CA about whether composition or regular GST fits your business model and growth plans.

Conclusion

Composition scheme is simpler and often cheaper if you have high expenses, stay within ₹1.5 crore, and sell mainly within your state. Regular GST gives you flexibility to grow, supply nationally, and lets your customers claim ITC—but it costs more admin time and money upfront. The right choice depends on your turnover, your customers, and where you want to be in three years. There is no one-size-fits-all answer.
