Key Takeaways

The composition scheme trades tax rate for capability: a low flat rate on turnover and quarterly filing, in exchange for no GST on invoices, no ITC, and no interstate sales.
Eligibility caps at ₹1.5 crore turnover for goods dealers (₹75 lakh in certain NE states), with a separate 6% scheme for service providers up to ₹50 lakh. Restaurants qualify only if they do not serve alcohol.
Composition taxpayers file CMP-08 quarterly and GSTR-4 annually, not GSTR-1 and GSTR-3B. Crossing ₹1.5 crore mid-year forces an auto-exit with back taxes.
It suits a single-state, local, B2C shop whose customers never ask for ITC, and it traps anyone planning interstate sales, marketplace listings, or B2B clients who need credit.

The GST composition scheme promises small business owners the simplest possible GST life - 1% tax, quarterly filing, almost no paperwork. For the right business, it's a gift. For the wrong one, it locks you out of ITC, e-commerce, and interstate sales.

This guide explains the GST composition scheme in 2026 - who qualifies, who should opt in, and who should run the other way.

What is the GST composition scheme?

The composition scheme lets eligible small businesses pay GST at a low flat rate on turnover and file returns quarterly, instead of monthly. You cannot charge GST on your invoices, cannot claim ITC, and cannot sell across state borders.

Who is eligible?

Dealers in goods (not interstate)
Restaurants not serving alcohol
Service providers up to ₹50 lakh turnover (separate scheme)

Who is NOT eligible?

E-commerce sellers on Amazon, Flipkart, Meesho
Manufacturers of ice cream, pan masala, tobacco
Casual and non-resident taxable persons
Suppliers of non-taxable goods

Manufacturers: 1% (0.5% CGST + 0.5% SGST)
Traders: 1%
Restaurants (no alcohol): 5%
Service providers under special scheme: 6%

Benefits of opting in

Common mistakes with composition

Crossing ₹1.5 Cr mid-year - auto-exit with back taxes

Frequently Asked Questions

Is composition scheme good for small shops?

Yes if they sell within one state, cash or local B2C only, and don't need ITC. See GST for shop owners.

Can freelancers opt for composition?

Service providers have a separate 6% scheme up to ₹50 lakh. See GST for freelancers.

Can I switch from composition to regular?

Yes, file CMP-04 during the financial year or automatically when turnover exceeds ₹1.5 Cr.

Do I need to file GSTR-1 under composition?

No. Composition taxpayers file CMP-08 quarterly and GSTR-4 annually.

Can composition dealers claim input tax credit?

No. That is the primary drawback.

Is composition scheme available for Pvt Ltd?
