Regular GST vs Composition Scheme: Key Differences & Which to Choose (2026)

Regular GST vs Composition Scheme: Which One Should Your Business Choose in 2026?

This guide breaks down both schemes in plain language, compares them side by side, and helps you decide which one fits your business — based on how GST actually works under the CGST Act, 2017.

What Is the Regular GST Scheme?

The Regular Scheme is the standard, default way of paying GST in India. Every business that registers under GST is placed here unless it specifically opts for the Composition Scheme.

Under this scheme, you:

• Charge GST on every invoice at the rate applicable to your goods or service (commonly 5%, 12%, 18%, or 28%)
• Collect that GST from your customer and deposit it with the government
• Claim Input Tax Credit (ITC) on the GST you pay to your suppliers
• Can sell across state lines and through e-commerce platforms without restriction
• File returns monthly (or quarterly under the QRMP scheme for smaller taxpayers), plus an annual return

Picking between the Regular GST Scheme and the Composition Scheme is one of those decisions that looks small on paper but quietly shapes how your business runs for years. It decides your tax rate, how much paperwork lands on your desk every month, whether you can sell outside your home state, and even how seriously bigger buyers take your invoices.

We get asked about this constantly by first-time GST registrants, so here's the plain-language version — what each scheme actually means, where they differ, and how to figure out which one fits your business, based on what Section 10 of the CGST Act and the GST portal actually say.

The Regular Scheme, In Plain Terms

Think of the Regular Scheme as GST's default setting. Unless you deliberately opt into something else, this is where every new registration lands.

Here's what it involves in practice:

• You charge GST on each sale at whatever rate applies to your product or service — usually 5%, 12%, 18%, or 28%
• That tax gets collected from the customer and handed over to the government
• You can claim back the GST you've already paid on your own purchases (this is Input Tax Credit, and it matters more than people expect)
• Selling to another state or through an online marketplace is completely fine
• Returns go in monthly, or quarterly if you're on the QRMP scheme, plus one annual filing

One thing worth knowing: there's no turnover ceiling here. A shop making ₹8 lakh a year and a factory making ₹80 crore can both sit in the Regular Scheme, side by side.

The Composition Scheme, created under Section 10 of the CGST Act, is an optional, simplified route meant for small taxpayers. Instead of charging GST slab-wise on every sale, you pay a small flat percentage of your total turnover directly to the government.

Key features:

• A fixed, low tax rate instead of standard slab rates

• You cannot show GST separately on your invoice or collect it from the customer — it comes out of your own margin
• No Input Tax Credit on purchases
• Only intra-state (within your own state) supply is allowed
• Much lighter compliance — a small number of filings a year instead of monthly returns

And the Composition Scheme?

The Composition Scheme comes from Section 10 of the CGST Act, and it exists for one reason — to take the compliance load off small businesses. Instead of applying GST slab rates to every invoice, you pay a flat percentage of your total turnover, full stop.

A few things define it:

• A low, fixed rate instead of 5–28% slabs
• No showing GST on your bill, and no collecting it from the customer — whatever you owe comes out of your own pocket
• Zero Input Tax Credit
• Sales restricted to within your own state
• A lighter filing calendar — a handful of filings a year instead of a dozen-plus

It's a genuinely useful option if your business is small, local, and doesn't lean heavily on ITC anyway.

Who's Actually Eligible?

Turnover in the previous financial year decides this, and the limit shifts depending on what you sell:

• Makes inter-state outward supplies
• Sells through an e-commerce operator who collects tax at source
• Manufactures notified goods such as ice cream, pan masala, or tobacco products
• Is a casual taxable person or a non-resident taxable person
• Supplies goods that are not taxable under GST

You're ruled out of the Composition Scheme if you:

• Supply goods or services across state lines
• Sell through an e-commerce platform that collects tax at source
• Manufacture certain notified goods — pan masala, tobacco, and ice cream fall in this bucket
• Operate as a casual or non-resident taxable person
• Deal in goods that fall outside GST altogether

And if your turnover crosses the limit mid-year, the scheme doesn't just quietly end — you're required to file Form GST CMP-04 within seven days and move to the Regular Scheme from that point.

Tax Rates, Side by Side

On paper, Composition looks like the cheaper option every time. In practice, it depends heavily on your margins and how much ITC you'd otherwise be claiming — which brings us to the part that actually decides most people's choice.

This is where the two schemes genuinely diverge in impact on your bottom line.

Under the Regular Scheme, when you buy raw materials, inventory, or services and pay GST on them, you can claim that amount back as Input Tax Credit and set it off against the GST you collect from customers. In effect, you only pay tax on the value you add, not on the full sale price.

Under the Composition Scheme, you get no such credit. The GST you pay on your purchases becomes a straight cost that adds to your expenses, and on top of that, you still pay the flat composition rate on your total sales.

For example: a trader buying goods worth ₹10 lakh and paying 18% GST on them (₹1.8 lakh) cannot recover that amount under the Composition Scheme — it simply adds to the cost of goods. A regular taxpayer in the same position would adjust that ₹1.8 lakh against output tax liability.

Input Tax Credit — the Part That Actually Matters

This is where the two schemes really part ways.

Under the Regular Scheme, GST paid on your purchases — raw material, stock, services, equipment — comes back to you as credit, which you set off against the tax you collect. You're effectively taxed only on the value you've added, not the whole sale price.

Under Composition, none of that applies. GST on your purchases just becomes a cost, full stop, and you still pay the flat composition rate on top of your total sales.

A quick example makes this clearer: say a trader buys ₹10 lakh worth of goods and pays 18% GST on them — that's ₹1.8 lakh. A Composition dealer can't recover a rupee of that; it just sits in their cost of goods. A Regular taxpayer, on the other hand, adjusts that same ₹1.8 lakh against what they owe in output tax.

Which is exactly why Composition tends to work better for businesses with low input costs and healthy margins — small retail, local services — and worse for anyone buying a lot of taxable inputs, like manufacturers or B2B traders.

Filing and Paperwork

This is the Composition Scheme's biggest selling point, honestly.

If you're running things without a dedicated accounts team, five filings a year versus twenty-four-plus is a real difference in time and in what you pay your CA.

Under the Composition Scheme, you issue a Bill of Supply, not a tax invoice, because you are not permitted to collect GST from customers. This matters for B2B relationships: a GST-registered buyer cannot claim ITC on a Bill of Supply, which makes composition dealers less attractive to business customers who want to recover input tax.

Invoices and How Customers See You

Composition dealers issue a Bill of Supply — not a tax invoice — because charging GST separately isn't allowed. That has a real downside for B2B relationships: a GST-registered buyer can't claim ITC against a Bill of Supply, so composition dealers often look less attractive to business customers trying to recover their own input tax.

Regular taxpayers issue a standard tax invoice with GST broken out, which lets B2B buyers claim their own credit. For businesses that sell mostly to other businesses rather than individual consumers, this one point often settles the whole decision.

What About Selling Across States or Online?

This catches a surprising number of small businesses off guard:

• Composition Scheme: Intra-state sales only. No selling to another state, and no selling through marketplaces like Amazon or Flipkart, since they're required to collect tax at source.
• Regular Scheme: No restriction at all — sell anywhere in India, on any platform.

If online selling or expansion beyond your home state is even a possibility down the line, Composition will box you in. That alone eliminates it for most e-commerce sellers before anything else gets weighed.

Full Comparison, One Table

Composition Scheme — Pros

• Lower, predictable tax rate

• Minimal paperwork and fewer return filings
• Lower compliance cost (less dependency on accountants)

Composition Scheme — Cons

• No ITC, which raises your effective cost of purchases

• Cannot sell interstate or on e-commerce platforms
• Less attractive to B2B/GST-registered buyers
• Growth is capped by the turnover threshold

Regular Scheme — Pros

• Full ITC benefit reduces effective tax burden

• No restriction on turnover, geography, or sales channel
• Builds credibility with B2B customers and larger clients
• Necessary for businesses planning to scale

Regular Scheme — Cons

Where Each One Wins and Where It Doesn't

Composition Scheme keeps your tax rate low and predictable, and cuts down the paperwork to almost nothing — but you lose ITC entirely, you're stuck selling within your state, B2B buyers tend to look past you, and growth bumps straight into the turnover ceiling.

Regular Scheme gives you full ITC, no cap on turnover or geography, and credibility with bigger, GST-registered clients — but it demands proper bookkeeping, more frequent filings, and usually some professional help to stay compliant.

There's no universal right answer — it depends on how your business actually operates:

Choose the Composition Scheme if you:

• Run a small, local business selling mainly to individual consumers (kirana store, boutique, salon, small restaurant)

• Operate within a single state only
• Have turnover comfortably under the applicable limit
• Want to minimise compliance effort and don't claim much ITC anyway

Choose the Regular Scheme if you:

• Sell to other GST-registered businesses (B2B)

• Plan to sell online, through marketplaces, or across state borders
• Have significant purchases on which you'd want to claim ITC
• Expect your turnover to grow past the composition threshold

As a rule of thumb: the Composition Scheme favours simplicity, the Regular Scheme favours scalability. If growth, interstate supply, or B2B credibility matter to you, the Regular Scheme is usually the better long-term choice, even with the extra compliance.

So, Which One Should You Pick?

Go with Composition if you run a small, local operation — a kirana store, a salon, a neighbourhood restaurant — sell mostly to individual customers within one state, stay well under the turnover limit, and don't have much ITC to claim in the first place.

Go with Regular if you sell to other GST-registered businesses, want the option to sell online or across state lines, have meaningful purchases you'd want credit on, or expect to outgrow the composition threshold before too long.

A simple way to remember it: Composition is built for simplicity, Regular is built for scale. If growth, interstate reach, or B2B trust matter to you, Regular is almost always the better long-term call, extra paperwork and all.

Switching Between the Two

Moving from Regular to Composition means filing Form GST CMP-02 on the GST portal before the financial year starts — generally by 31st March — to opt in for the year ahead.

Going the other way is easier: you can voluntarily opt out any time using Form GST CMP-04. It also kicks in automatically the moment your turnover crosses the limit, and you then have seven days to file it.

One more thing to keep in mind — once you move to Regular, you'll need to file Form ITC-01 to claim credit on existing stock, semi-finished goods, and capital assets, since that window to claim it doesn't stay open indefinitely.

1. Can a service provider opt for the Composition Scheme? Yes. Since 2019, service providers (and businesses supplying both goods and services) with turnover up to ₹50 lakh in the preceding financial year can opt for the composition scheme for services, at a 6% rate.

2. Is GST registration compulsory for the Composition Scheme? Yes. You must first be registered under GST and then separately opt in for the Composition Scheme by filing Form CMP-02.

3. Can a composition dealer issue a tax invoice? No. A composition dealer must issue a Bill of Supply, since GST cannot be charged separately to the customer.

4. What happens if a composition dealer's turnover exceeds the limit mid-year? The scheme lapses automatically from the day the limit is crossed. The taxpayer must file Form CMP-04 within seven days and start complying with Regular Scheme rules, including charging GST and filing regular returns, from that date.

5. Can a composition taxpayer claim Input Tax Credit? No. Businesses under the Composition Scheme cannot claim ITC on purchases, which is one of the biggest trade-offs of the scheme.

Quick Answers to Common Questions

Can a service provider use the Composition Scheme?

Yes. Since 2019, service providers — and businesses offering a mix of goods and services — with turnover up to ₹50 lakh in the previous year can opt in at a 6% rate.

Do I need GST registration before opting for Composition?

Yes, always. You register under GST first, then file Form CMP-02 separately to opt into Composition.

Can a composition dealer issue a tax invoice?

No — only a Bill of Supply, since charging GST separately to customers isn't permitted under this scheme.

What happens if turnover crosses the limit partway through the year?

The scheme lapses from that exact day. You'll need to file Form CMP-04 within seven days and start following Regular Scheme rules — charging GST, filing returns — from then on.

Can a composition taxpayer claim ITC?

No. That's the single biggest trade-off of choosing this scheme.

Can I sell on Amazon or Flipkart under Composition?

No. Anyone selling through an e-commerce operator that collects tax at source is automatically ineligible.

Both schemes exist for different kinds of businesses, and GST law does not intend one to be "better" than the other in absolute terms. A small neighbourhood store and a growing B2B manufacturer have very different compliance capacities and very different needs from their GST structure — which is exactly why the Composition Scheme and Regular Scheme coexist.

If you are still unsure which scheme fits your business, or you need help with GST registration, switching schemes, or filing returns correctly, LegalDevIndia's GST advisory team can review your business model and recommend the right structure before you register.

The Bottom Line

Neither scheme is objectively "better" — they're built for different kinds of businesses. A local shop and a growing B2B manufacturer have completely different compliance capacity and completely different needs, which is exactly why both options exist side by side under GST law.
