Not every small business needs to deal with monthly GST returns, tax invoices with itemised tax lines, and full input tax credit reconciliation. The GST composition scheme was designed as a simplified alternative for eligible small taxpayers who are willing to trade input tax credit and inter-state flexibility for lower compliance effort and a flat, turnover-based tax payment.
This guide explains who can opt in, what changes once you do, and how composition returns work - so you can decide whether it fits your business.
What the composition scheme actually changes
Under the composition scheme, instead of charging GST on every invoice line and computing tax liability supply-by-supply, an eligible taxpayer pays tax as a fixed percentage of their turnover, reported and paid periodically. In exchange, the taxpayer gives up the right to collect tax separately from customers and cannot claim input tax credit on purchases.
Who can opt for the composition scheme
Eligibility is generally based on aggregate turnover in the preceding financial year staying within a specified limit, and this limit differs for goods suppliers versus certain categories of service providers. Because this limit is revised periodically by the GST Council, always check the current turnover limit on the GST portal before opting in.
Who typically cannot opt in
- Businesses making inter-state outward supplies
- Sellers supplying goods through an e-commerce operator that is required to collect tax at source - this is particularly relevant if you sell through marketplaces
- Manufacturers of certain notified goods
- Casual taxable persons and non-resident taxable persons
- Service providers beyond the specific limit carved out for a small services composition option (restaurants serving food, other than those serving alcohol, are usually treated as an exception within goods-oriented composition rules)
This last point matters a great deal for the typical OneBooks GST audience: if you sell across India through Amazon, Flipkart, Meesho, or similar platforms, you will generally not be eligible for the composition scheme, because marketplace sales usually involve inter-state supply and TCS-collecting e-commerce operators. Composition tends to suit small, single-state retailers, traders, and eligible restaurants rather than marketplace-first sellers.
Composition tax rates by category
Rates are structured as a small flat percentage of turnover and differ by category - broadly, manufacturers and traders fall into one bracket, restaurant services (not serving alcohol) into another, and the separate small-service-provider composition option into a third. Because these percentages can change, confirm the current applicable rate for your category on the GST portal rather than relying on a fixed figure.
| Category | Nature of business | Return to file |
|---|---|---|
| Traders / manufacturers | Supply of goods within one state | Quarterly statement-cum-payment (CMP-08) + annual GSTR-4 |
| Restaurants (non-alcohol) | Restaurant/catering services | Quarterly statement-cum-payment (CMP-08) + annual GSTR-4 |
| Eligible small service providers | Services under the separate composition option for services | Quarterly statement-cum-payment (CMP-08) + annual GSTR-4 |
What composition dealers cannot do
- Cannot show GST separately on the invoice - instead of a tax invoice, a composition dealer issues a Bill of Supply
- Cannot collect tax from the customer
- Cannot claim input tax credit on purchases
- Cannot make inter-state outward supplies of goods
- Must mention that they are a composition taxable person not eligible to collect tax, on the Bill of Supply and at their place of business, as required
Returns and the compliance calendar
Composition taxpayers file a simplified quarterly statement (commonly referred to as CMP-08) to pay tax for the quarter, and an annual return (GSTR-4) summarising the year. This is considerably lighter than the monthly GSTR-1 and GSTR-3B cycle that regular taxpayers follow - see our GST return filing calendar for how the regular-scheme cycle compares.
Switching between composition and regular scheme
A taxpayer usually opts into the composition scheme at the start of a financial year. If turnover crosses the eligibility limit during the year, switching out to the regular scheme becomes mandatory from that point. Moving between schemes has knock-on effects - for example, stock held on the date of transition may need a specific declaration, and input tax credit treatment changes depending on the direction of the switch. These transition filings are procedural but easy to miss, so plan the switch with your accountant rather than leaving it to the last date.
Composition vs regular scheme - a quick comparison
| Aspect | Composition scheme | Regular scheme |
|---|---|---|
| Return frequency | Quarterly payment + annual return | Monthly/periodic GSTR-1 and GSTR-3B |
| Input tax credit | Not available | Available, subject to conditions |
| Inter-state sales | Not permitted | Permitted |
| Marketplace selling | Generally not eligible | Standard route for most sellers |
| Tax shown on invoice | Not shown separately (Bill of Supply) | Shown as CGST/SGST/IGST on tax invoice |
| B2B buyer appeal | Lower - buyer cannot claim ITC on your supply | Higher - buyer can claim ITC |
Is composition the right fit for you
Composition tends to work well for small, single-state businesses with simple operations and mostly retail or B2C customers who do not need an ITC-bearing tax invoice. If your growth plan includes selling across states, listing on marketplaces, or serving B2B customers who expect input tax credit, the regular scheme - paired with proper accounting software to keep invoicing and records organised - is usually the better long-term fit.
A practical way to think about the trade-off
Consider a single-state trader with steady local retail sales and a handful of B2B customers who occasionally ask for GST-inclusive invoices with credit. Under composition, this trader pays a flat percentage of turnover with minimal return filing, but cannot pass on an ITC-bearing invoice to those B2B customers, which can make competing for that segment harder over time. The same trader under the regular scheme takes on monthly filing and full invoicing discipline, but can serve both retail and B2B customers, claim credit on purchases, and expand to other states or marketplaces without switching schemes later. Neither option is universally better - the right choice depends on your customer mix, growth plans, and appetite for compliance work, and it's worth revisiting the decision each year rather than assuming your first choice should be permanent.
Invoicing discipline under composition
Because composition dealers cannot issue a tax invoice with GST shown separately, it's worth being deliberate about your Bill of Supply format so it still looks professional and complete - business name, GSTIN, address, a serial number, description of goods or services, and the total value, even without a tax breakup. Buyers sometimes query why no GST is shown; a brief note on the document referencing your composition status can pre-empt that confusion.
Frequently asked questions
What is the turnover limit for the composition scheme?
The limit differs for goods and for the separate services composition option, and it is revised periodically. Check the current limit on the GST portal before opting in.
Can restaurants opt for the composition scheme?
Restaurants supplying food and non-alcoholic beverages are generally eligible under the composition rules applicable to that category, subject to the turnover limit. Confirm current eligibility on the GST portal.
Can I sell on Amazon or Flipkart under the composition scheme?
Generally no. Composition taxpayers are typically barred from supplying through e-commerce operators required to collect tax at source, which covers most major marketplaces.
What return do composition dealers file?
Composition taxpayers file a quarterly statement-cum-payment (commonly CMP-08) and an annual return (GSTR-4), instead of the monthly return cycle regular taxpayers follow.
Can I switch back to composition after opting out?
Yes, subject to conditions and the standard rule that composition can generally be opted into from the start of a financial year, provided you remain within the eligibility limit. Verify the current procedure on the GST portal.
How OneBooks GST handles it
OneBooks GST is built around exactly this cycle. It imports sales data, prepares GSTR-1, parses bank statements, and exports to Tally XML, Miracle, Profit NX, Excel and CSV.
Because OneBooks GST keeps each GSTIN in its own organisation context, a business registered in several states can work through one registration at a time.
