The Composition Dealer Who Charged GST on His Bill — A Mistake That Costs More Than the Tax

A kirana shop owner in Pune opted for the Composition Scheme to keep his GST filings simple. Business was good, so he started printing "GST @ 1%" on his customer bills and collecting it on top of his prices. He thought he was being compliant. In reality, he had broken one of the clearest rules in the scheme — and exposed himself to a demand for the entire amount he had wrongly collected, plus penalty.

This is one of the most common and most expensive mistakes composition dealers make. Let's fix it.

The Correct Rule, Simply Explained

The Composition Scheme under Section 10 of the CGST Act lets small businesses pay GST at a low flat rate on turnover — typically 1% for traders and manufacturers, 5% for restaurants (not serving alcohol), and 6% for eligible service providers under the special composition route.

The trade-off is simple: you pay a low rate out of your own pocket, but you cannot pass that tax on to your customers.

Section 10(4) is unambiguous — a composition taxpayer is not allowed to collect any tax from the recipient. And under Section 31(3)(c), a composition dealer must issue a Bill of Supply, not a tax invoice. The bill must carry the words "composition taxable person, not eligible to collect tax on supplies."

So the GST you owe is funded from your margin, not charged separately on the bill. Equally, a composition dealer cannot claim input tax credit on purchases — the low rate already accounts for that.

Four Practical Tips for Composition Dealers

1. Switch your billing format to a Bill of Supply

Ask your software or accountant to change the document type. Remove the tax columns. Add the mandatory declaration line about being a composition taxpayer. A Pune trader paying 1% on a Rs 50 lakh turnover owes Rs 50,000 from his own pocket — he should price his goods to absorb this, not show it as a line item.

2. Display your status at your place of business

The rules require you to display "composition taxable person" on a notice board at your principal and additional places of business. This keeps you transparent and avoids confusion for B2B buyers who might otherwise expect ITC.

3. File CMP-08 quarterly and GSTR-4 annually

Composition dealers don't file the regular monthly returns. You pay tax through Form CMP-08 every quarter and file the annual return in Form GSTR-4. Mark these dates so you never miss them.

4. Watch your turnover limit and ineligible activities

The scheme is generally available up to Rs 1.5 crore turnover (Rs 75 lakh in some special category states). You cannot opt in if you make inter-state outward supplies, supply through an e-commerce operator that collects TCS, or deal in goods like ice cream, pan masala, and tobacco that are excluded.

FAQ of the Day

"I'm a composition dealer who sells only within my state. Can I sell to a customer in another state?"

No. Making inter-state outward supplies disqualifies you from the Composition Scheme. The moment you ship goods to a buyer in another state, you breach the eligibility condition and must move to the regular scheme. You can still buy from other states — the restriction applies only to outward supplies.

What NOT to Do

• Do not issue a tax invoice or show GST separately on your bills. If you collect tax you are not entitled to, the department can demand you deposit every rupee collected, with interest and penalty.
• Do not claim input tax credit on your purchases — it is simply not available under this scheme.
• Do not assume you can keep the scheme forever. If your turnover crosses the limit mid-year, you must shift to the regular scheme and start charging GST normally from that point.
• Do not forget the declaration line on your Bill of Supply — its absence is a documentation defect.
