Is 1% composition GST cheaper than regular GST? The answer depends on what your customer will pay, how much eligible input tax credit (ITC) your purchases create, and whether you can legally use the scheme. A composition taxpayer generally pays a small percentage of turnover but cannot charge GST separately or claim ITC. A regular taxpayer charges the applicable GST and may offset eligible input tax against output tax. Comparing 1% with 18% alone therefore gives the wrong answer.
Quick answer: Composition can be attractive for an eligible local B2C trader selling at a fixed tax-inclusive consumer price with modest input costs. Regular GST often works better when business customers expect a creditable tax invoice, input credits are substantial, or composition eligibility is unavailable. The worked numbers below are assumptions, not a recommendation for any GSTIN.
Our composition scheme guide covers eligibility and opting in. This article focuses on the commercial comparison: actual cash left after purchases and tax under two realistic pricing arrangements. You can estimate a flat levy in the Composition Scheme Calculator; it does not compare your full profit or establish eligibility on its own.
The legal differences that change the maths
| Question | Composition scheme | Regular GST |
|---|---|---|
| Tax on outward supply | Prescribed percentage of turnover for the eligible category | GST at the applicable rate on taxable supply |
| Tax charged separately to buyer? | No; issue a bill of supply | Usually shown on a tax invoice, subject to invoicing rules |
| Supplier ITC on purchases? | No | Eligible ITC may offset output tax, subject to Section 16 and other conditions |
| Can a registered buyer claim ITC from this seller’s document? | No creditable tax invoice from a composition supplier | Potentially, if the buyer meets its own ITC conditions |
| Ordinary compliance | Quarterly CMP-08 payment statement and annual GSTR-4 | GSTR-1 and GSTR-3B, monthly or QRMP where eligible |
| Inter-State outward supply | Generally not permitted under the composition conditions | May be made with the applicable IGST treatment |
The GST Portal welcome kit explains the no-ITC, no-separate-tax and bill-of-supply restrictions and the quarterly/annual filing pattern. The CBIC composition rules prescribe the bill-of-supply wording and withdrawal procedure. A buyer’s ability to claim ITC on a regular invoice is a separate legal test; it is never automatic merely because tax appears on the invoice.
For the commonly used categories, the composition levy is 1% for eligible traders/manufacturers, 5% for qualifying restaurant services, and a separate 6% route for eligible service or mixed suppliers up to ₹50 lakh. The standard goods/restaurant threshold is generally ₹1.5 crore preceding-year PAN-based aggregate turnover, with ₹75 lakh in specified special-category states. Categories, exclusions, turnover treatment and current notifications must be checked before comparing tax. The CBIC GST update and GST Portal welcome kit describe these limits and rates.
Example 1: a local B2C trader with a fixed customer price
Assume an eligible intra-State trader sells only goods that attract 18% GST under the regular scheme. Over one comparison period:
- Customers will spend ₹10,00,000 in total, whichever scheme the shop uses. This is the fixed tax-inclusive price under regular GST.
- The shop pays suppliers ₹6,00,000 in total, including assumed 18% GST on eligible purchases.
- All ₹91,525 of the purchase GST would satisfy ITC conditions if the shop were regular. Ignore stock changes, expenses other than purchases, RCM, exempt sales and income tax.
- Under composition, assume the shop’s relevant turnover for the 1% levy is ₹10,00,000 and no GST is separately charged.
| Cash and tax for the same customer spend | Composition | Regular GST |
|---|---|---|
| Cash collected from customers | ₹10,00,000 | ₹10,00,000 |
| Supplier invoice paid, including GST | ₹6,00,000 | ₹6,00,000 |
| Output GST contained in customer price | Not separately charged | ₹1,52,542 |
| Eligible purchase ITC | Not allowed | ₹91,525 |
| Net GST paid after credit, or composition levy | ₹10,000 | ₹61,017 |
| Illustrative cash left before other costs | ₹3,90,000 | ₹3,38,983 |
Under the regular scheme, ₹10,00,000 ÷ 1.18 gives a taxable sale value of about ₹8,47,458 and output GST of about ₹1,52,542. The ₹6,00,000 purchase invoice contains about ₹91,525 of assumed eligible GST, leaving roughly ₹61,017 to pay. Composition instead leaves purchase GST embedded in cost and requires a ₹10,000 levy. With the same consumer price and purchase cash cost, composition leaves about ₹51,017 more in this narrow example.
That result reverses when margins are thinner or credits are larger. Keep the same ₹10,00,000 fixed customer price but suppose eligible purchase invoices total ₹9,50,000 including 18% GST. The pre-tax cash spread is ₹50,000. Composition would leave ₹40,000 after its ₹10,000 levy. Regular GST would leave about ₹42,373 after the net GST calculation, assuming all purchase ITC is eligible. The regular scheme is ahead by about ₹2,373. The point is the method: compare money left after tax, not only the headline GST rate.
These are rounded illustrations. Confirm the product’s actual rate with the GST Rate Finder and check invoices/credits against your books; the assumed 18% may not fit your goods or dates.
Example 2: a B2B customer who can use a tax invoice
Now assume the same trader sells at a ₹10,00,000 price before GST to a registered buyer that is willing and eligible to pay ₹1,80,000 GST on top and claim its own ITC. Keep the ₹6,00,000 tax-inclusive supplier invoice and assumed ₹91,525 eligible input credit.
The regular seller collects ₹11,80,000, pays ₹6,00,000 to the supplier and roughly ₹88,475 net GST (₹1,80,000 output less ₹91,525 input credit). That leaves about ₹4,91,525 before other costs. A composition seller cannot add GST to a creditable tax invoice. If the buyer agrees to pay only ₹10,00,000 total for the same goods, the composition seller’s cash left after the supplier bill and 1% levy is ₹3,90,000. On these different buyer-price assumptions, regular GST is ahead by about ₹1,01,525.
Do not treat the B2C and B2B examples as interchangeable. If the buyer negotiates a lower before-tax price, cannot claim ITC, or the supplier’s purchase credit is blocked, the result changes. Ask what price the customer will actually pay, not merely what rate the seller will report.
A simple decision worksheet
Before using the Composition Scheme Calculator, collect these five inputs for one consistent period:
- Sales by customer type: B2C, B2B, taxable, exempt and any inter-State outward sales. A composition option may be unavailable for the business model.
- Actual selling price: Record whether the quoted customer price includes GST under the regular scheme. A fixed retail shelf price is different from a B2B price quoted plus GST.
- Purchases and usable ITC: Separate invoice GST from amounts that are actually creditable. Check Section 16 conditions, blocked credits and relevant reversals; our GSTR-2B mismatch guide explains one reconciliation risk.
- Composition turnover and rate: Use the correct category and turnover base. Do not apply 1% to a service supplier or assume every restaurant is eligible.
- Compliance and growth: Allow for the filing workload, B2B customer requirements and the chance of crossing a threshold mid-year. See the CMP-08 guide and GST Due Dates Calendar.
Calculate the composition levy with our Composition Scheme Calculator. Calculate output GST on a chosen taxable value or reverse-calculate a tax-inclusive price with the GST Calculator. Then subtract eligible ITC and compare after-tax gross margin using the same customer-price assumption. Neither tool decides the legal availability of composition or a specific ITC claim.
Filing and switching considerations
Composition taxpayers file CMP-08 quarterly and GSTR-4 annually under the ordinary scheme. Regular taxpayers file GSTR-1 and GSTR-3B, monthly or under QRMP when eligible; QRMP is still a regular-taxpayer scheme, not composition. A taxpayer already registered under the regular scheme generally opts into composition from the beginning of a financial year through the prescribed portal process, subject to eligibility. Do not assume an immediate mid-year switch. If composition conditions cease to be met, the CBIC rules describe withdrawal and the move to regular tax. See our composition eligibility guide for the broader checklist.
Frequently asked questions
Is composition tax always cheaper because it is only 1%?
No. The 1% applies only to an eligible trader/manufacturer category and is paid without purchase ITC. A regular business may offset eligible ITC and may charge GST separately to a buyer. Compare after-tax margin under realistic pricing.
Can a composition dealer collect the 1% from customers as GST?
No. A composition taxpayer cannot collect GST separately and issues a bill of supply rather than a regular tax invoice. The levy is a cost the seller must account for in pricing.
Can a B2B buyer claim ITC from a composition seller?
No creditable GST is separately charged on the composition seller’s bill of supply. The buyer’s ITC analysis differs when buying from a regular supplier that issues a valid tax invoice.
Does a regular GST seller always receive all purchase ITC?
No. ITC depends on the statutory conditions and the nature of the purchases. Blocked or unreconciled credit can materially change the comparison.
What if my regular sale is priced ₹10 lakh including 18% GST?
Then the taxable value is about ₹8,47,458 and output GST about ₹1,52,542, not ₹1,80,000. Use a reverse GST calculation for an inclusive price.
Can a composition dealer sell goods to another state?
Composition has a general restriction on inter-State outward supplies. Inter-State purchases are a different question. Check the current scheme conditions before choosing it for an online or cross-border sales model.
Is QRMP the same as composition?
No. QRMP changes the return/payment frequency for an eligible regular taxpayer. It does not create the composition no-ITC or bill-of-supply rules.
Can a regular taxpayer switch to composition in the middle of a year?
An already-registered regular taxpayer ordinarily opts from the start of the next financial year via the prescribed process. A newly registering business has a separate choice at registration. Verify the GST Portal workflow and eligibility before acting.
