GST registration and the choice of the composition scheme are separate decisions. First establish whether your business must register; if it does, check whether it qualifies for composition. Regular taxpayers generally follow GSTR-1 and GSTR-3B filing arrangements, while composition taxpayers use quarterly CMP-08 payments and annual GSTR-4 reporting. Composition can reduce filing complexity, but it also limits how you invoice, claim input tax credit and supply goods or services.
What is the difference between regular GST and the composition scheme?
Regular GST is the normal framework for registered taxpayers. The composition levy is an optional, simplified route for registered businesses that satisfy its conditions. It is not an exemption from deciding whether registration is required, and it is not available to every small business.
| Area | Regular taxpayer | Composition taxpayer |
|---|---|---|
| Eligibility | Registration depends on the applicable GST liability rules. A registered person may use composition only if eligible. | Must meet the applicable turnover, business-category and supply restrictions; limits can depend on state and business facts. |
| Outward-supply reporting | GSTR-1 applies to taxpayers covered by the filing rules, including nil filing for an applicable period with no business activity. | Excluded from GSTR-1. |
| Returns and payments | GSTR-1 and GSTR-3B under the applicable filing arrangement; eligible taxpayers may use QRMP. | Quarterly self-assessed tax payment through CMP-08 and annual GSTR-4 under the composition process. |
| Customer document | Tax invoice when required under invoice rules. | Bill of supply; GST is not collected separately from the customer under the scheme. |
| Input tax credit | May claim eligible credit subject to statutory conditions. | Cannot claim input tax credit on purchases. |
| Supply restrictions | Normal GST framework applies, subject to the Act and rules. | Includes restrictions such as limits on inter-State outward supplies and other conditions. |
The choice matters especially when your customers are GST-registered businesses: they may value eligible input tax credit shown on a regular tax invoice. A composition taxpayer cannot pass that credit through. Review the applicable rules and restrictions for your business before opting in. GST Portal; CBIC GST.
Does a small business have to register before choosing composition?
Registration liability comes first. A small business should determine whether registration is required under the rules that apply to its turnover, supplies, location and other circumstances; size alone does not mean that every business must register. Composition is a route for eligible registered persons, not a way to avoid registration when it is due.

The GST Portal describes a common registration application flow for normal and composition applicants, with an option to indicate composition. It also says the effective date for a normal taxpayer’s registration depends on filing within the applicable period after liability arises. Registration is taxpayer-specific, so do not assume that one business’s answer applies to another. Check the portal’s current registration guidance and get professional advice if the facts are mixed or cross-state. GST Portal registration guide.
Who may qualify, and what turnover figures should you check?
Composition eligibility depends on more than a turnover figure: the applicable state, business category, supply mix and statutory exclusions or restrictions can change the result. The CBIC’s 2019 update reported a ₹1.5 crore goods threshold, a ₹75 lakh limit for specified states, and a separate ₹50 lakh threshold for certain service suppliers under a scheme introduced for services. These are dated published figures, not a complete current eligibility determination. Check current law, rules and notifications before relying on them. CBIC GST.
- Turnover and state: Confirm the limit and state-specific treatment currently applicable to your business.
- Business category and supply mix: Check whether your activity and the kinds of supplies you make are permitted.
- Customer geography: Assess restrictions on inter-State outward supplies and whether your customer base fits the scheme.
- Customer credit needs: Consider whether business customers need eligible input tax credit that composition treatment cannot provide.
Because rules and notifications may change, a threshold summary—particularly a 2019 summary—should not substitute for a fact-specific check against current CBIC and GST Portal material. Consider a tax professional where turnover, services, multiple states or mixed supplies make eligibility unclear.
What returns and payments does each route involve?
Regular taxpayers: GSTR-1, GSTR-3B and possibly QRMP
GSTR-1 reports outward supplies. Where it applies, the GST Portal says it must be filed even for a nil period with no business activity; composition taxpayers are excluded. The portal describes ways to prepare GSTR-1, including online entry, an offline returns tool and third-party applications through GST Suvidha Providers. Regular taxpayers also use GSTR-3B under their applicable filing arrangement. GST Portal returns guidance.
QRMP is an optional arrangement for eligible regular taxpayers. The portal describes quarterly filing of GSTR-1 and GSTR-3B alongside monthly tax payments. Its guidance gives a ₹5 crore turnover ceiling, but includes date-specific examples; verify current eligibility and conditions on the portal rather than treating that figure as timeless advice. GST Portal QRMP guidance.
Composition taxpayers: quarterly CMP-08 and annual GSTR-4
Composition taxpayers use CMP-08 for quarterly self-assessed tax payments and furnish GSTR-4 annually under the official composition process. This is a simpler reporting cadence, not a no-filing or no-payment arrangement. Confirm current due dates and portal requirements, since deadlines and workflows may change. GST Portal returns guidance.
What document should you give customers, and can you collect GST?
Regular taxpayers use a tax invoice when required under the invoice rules. Composition taxpayers issue a bill of supply and do not collect GST separately from customers under the scheme. If you use paper stationery, a bill-of-supply book can help organize those documents, but it is not a compliance guarantee: check that its fields meet current requirements.

It may not be. Composition has restrictions that include limits on inter-State outward supplies, so a business selling across state borders should verify whether its actual supply pattern is permitted before opting in. Also consider whether registered business customers need eligible input tax credit: composition taxpayers cannot claim credit on purchases or provide customers with credit through a regular GST tax invoice. If either geography or customer credit needs are central to the business, compare the restrictions and commercial effects before choosing.

How to make the decision
- Determine registration liability. Check the current rules for your turnover, supplies, location and circumstances; do not start by assuming that every small business must register.
- Test composition eligibility. Verify current turnover limits, state treatment, business category, supply mix and exclusions against current CBIC and GST Portal guidance.
- Map your customers and sales. Check where you make outward supplies and whether any inter-State restrictions affect your business.
- Compare the operating routine. Regular treatment involves the applicable GSTR-1 and GSTR-3B arrangement, with QRMP potentially available to eligible taxpayers; composition involves quarterly CMP-08 and annual GSTR-4.
- Evaluate the customer and purchase impact. Compare bill of supply and no separately collected GST under composition with regular invoicing, and account for the loss of input tax credit under composition.
- Confirm before opting in. Use current statutory and portal materials, and seek professional advice when eligibility or cross-state facts are not straightforward.
