Do I need GST for a small business in India?

The short answer

Most small businesses in India do not need GST registration to begin. You’re only required to register once your turnover crosses a threshold, or once you do one of a few specific things (sell across state lines, or sell on certain online marketplaces) that make it mandatory regardless of how small you are. If none of those apply, you can run a legitimate small business without GST.

Because the rules are wrapped in jargon, let’s make each case plain.

The turnover thresholds

For ordinary businesses operating within their own state, GST registration becomes compulsory once annual turnover crosses:

• ₹40 lakh for a business supplying goods (in most states).
• ₹20 lakh for a business supplying services (in most states).
• Lower limits, ₹20 lakh for goods and ₹10 lakh for services, apply in special-category (mostly north-eastern and hill) states.

Below these limits, an in-state business is generally not required to register. So a home baker, a local tuition teacher or a neighbourhood boutique earning under the threshold usually has no GST obligation at all.

When GST is mandatory regardless of turnover

Some situations require GST from day one, even if you’ve earned ₹0 so far. The main ones:

• Selling across state lines (inter-state supply), shipping a product to a customer in another state generally triggers mandatory registration.
• Selling through e-commerce marketplaces, platforms like Amazon and Flipkart typically require a GSTIN before you can list. (Recent rules relax this for some small sellers of exempt goods selling only within their own state, but it varies by platform and category, so always confirm with the marketplace.)
• Certain other cases, for example businesses liable under reverse charge, or non-resident taxable persons.

This is the single biggest surprise for new online sellers: you can’t usually wait for the ₹40 lakh threshold if you want to sell on the big marketplaces. Plan for GST from the start if that’s your channel.

When you genuinely don’t need it

You can normally skip GST if all of the following are true: your turnover is under the threshold, you sell only within your own state, and you sell directly (your own shop, WhatsApp, Instagram, or your own website) rather than through a marketplace that mandates it. Plenty of profitable home and local businesses operate happily in this zone for years.

That said, your other registrations still matter. A free Udyam (MSME) registration and a current account are worth getting regardless, see our guide on how to register a business in India.

Should you register voluntarily?

Sometimes registering before you have to makes sense. With GST you can claim input tax credit on your purchases, sell to companies that only buy from GST-registered suppliers, and sell across states or on any marketplace without restriction. The trade-off is compliance: regular returns to file and records to keep.

If your turnover is small and your costs are low, the composition scheme (open to businesses up to ₹1.5 crore turnover) lets you pay GST at a low flat rate with far simpler returns, though you can’t claim input credit or, generally, sell inter-state or via e-commerce under it. Weigh the credit and credibility against the paperwork.

How to register (it’s free)

GST registration is free and online at the official GST portal. You’ll need your PAN, Aadhaar, a business address proof, bank details and a photo; for a company or LLP, the incorporation documents too. A GSTIN is usually issued within a few working days.
