Composition scheme or regular GST: how a small shop should decide

Every small business that registers for GST hits the same fork: pay a flat 1% under the composition scheme, or charge GST and claim credits under the regular one. The usual advice is that composition is simpler, and it is. For some shops it also costs more. Here is how to tell which kind you are.

The two ways to pay GST

Under the regular scheme you charge GST on every sale, claim back the GST you paid on your purchases (input tax credit), and pay the government the difference. You issue tax invoices and file monthly or quarterly returns.

Under the composition scheme you pay a small flat percentage of your turnover instead, and that is the end of the calculation. You do not charge GST to your customers, you do not claim any credit on purchases, and you file far less. The price of that simplicity is a list of things you are no longer allowed to do.

Who can choose composition

  • Turnover: up to ₹1.5 crore in the previous financial year if you sell goods, or ₹75 lakh in some special category states. For services the limit is ₹50 lakh.
  • Only within your state: you cannot make sales to other states.
  • Not through e-commerce operators that collect tax at source, such as the big marketplaces, for goods.
  • Not for a few notified goods, such as ice cream, pan masala and tobacco products.

The rates are a share of turnover, not of profit:

  • 1% for manufacturers and traders (0.5% CGST + 0.5% SGST)
  • 5% for restaurants that do not serve alcohol
  • 6% for service providers who qualify

Which one costs you less?

What you actually pay depends on two things: the GST rate on what you sell, and how much you add on top of what you paid for it.

Take a shop where prices are fixed (MRP, or whatever the street charges), so the customer pays the same amount either way. Look at one ₹100 sale.

Shop A: groceries at 5%, bought for ₹90

Regular: GST inside the sale ₹4.76, minus GST inside the purchase ₹4.29

Pays ₹0.48

Composition: 1% of ₹100

Pays ₹1.00

Shop B: electronics accessories at 18%, bought for ₹70

Regular: GST inside the sale ₹15.25, minus GST inside the purchase ₹10.68

Pays ₹4.58

Composition: 1% of ₹100

Pays ₹1.00

The pattern holds generally. Composition saves money when your margin is wide and your goods carry a high rate. With thin margins on low-rate goods, the regular scheme is usually cheaper, because the tax you pay is only on the small amount you add.

These are simplified figures. They leave out your other costs, such as rent and transport, and the GST on those, which you can claim back under the regular scheme and cannot under composition. Run your own numbers for a normal month, with your accountant if you have one.

The question that settles it for many shops

Before the arithmetic, ask who buys from you. A registered business that buys from you wants a tax invoice so it can claim the GST back. A composition dealer cannot give one: you issue a Bill of Supply with no GST on it, and the buyer gets no credit.

For a kirana selling to families, that makes no difference. For a wholesaler selling to other shops, or a workshop doing jobs for companies, it can lose you customers, because buying from you costs them more than buying from a regular dealer.

What the paperwork looks like

Composition

  • CMP-08 every quarter, by the 18th of the month after the quarter: a short statement and the tax payment.
  • GSTR-4 once a year: an annual return summing up the quarters.
  • Bills of supply for your sales.

Regular

  • GSTR-1 (your sales) and GSTR-3B (the tax summary and payment), monthly or quarterly depending on your turnover and the scheme you pick.
  • Tax invoices with the GST split out, and matching your purchases against what your suppliers have reported.

If you are on composition and your turnover crosses the limit during the year, you move to the regular scheme from that day. Keep an eye on it, especially in a good festive season.

How to switch

To move to composition, an existing registered business files form CMP-02 on the GST portal before the start of the financial year, so by 31 March for the year starting 1 April. A new business can choose it while registering. To leave composition, you can opt out during the year, and you must leave once you cross the limit or start doing something the scheme does not allow, such as selling to another state.

Whichever you choose, Invoiceo makes the right document. In your business settings, set GST registration to Composition and your invoices become bills of supply, without a GST line. Leave it off and you get tax invoices with CGST, SGST or IGST worked out. You can try both in the free GST invoice generator under “More options”.

Questions people ask

Can a composition dealer sell to customers in another state?

No. Outward supplies to other states are not allowed under the scheme. If you start selling to other states, you have to move to the regular scheme. Buying from other states is fine.

Can I claim input tax credit under composition?

No. The GST you pay on purchases becomes part of your cost. That is one of the reasons composition can cost more for a shop with thin margins.

Do composition dealers need a GSTIN on their bills?

Yes. You are still registered and have a GSTIN, and it goes on your bills of supply. What you do not do is charge GST on them.

Did the 2025 GST rate changes change the composition rates?

The September 2025 changes reorganised the main GST rates on goods and services. The composition rates of 1%, 5% and 6% of turnover were not part of that change. Rates can change at any GST Council meeting, so check the CBIC site for the current figures.
