GST for Small Business in India

A small business in India must register for GST once its turnover crosses ₹40 lakh for goods or ₹20 lakh for services in a year. A few states have lower limits: ₹20 lakh for goods in Telangana, Uttarakhand, Puducherry and three north-eastern states, and ₹10 lakh for both in Manipur, Mizoram, Nagaland and Tripura. Below the limit, GST is optional, unless you sell goods to another state, sell through some e-commerce routes, or fall in another case where registration is compulsory.

Once registered, you have three main jobs:

Very small businesses can choose the composition scheme instead. They pay a flat 1%–6% of turnover and file less, but cannot claim input tax credit or sell across state lines.

The GST registration limit is based on your aggregate turnover for the financial year. It covers all your taxable, exempt and export sales across India under one PAN, before GST.

The ₹40 lakh goods limit applies only if you sell goods within your own state and supply no taxable services. If you sell both goods and services, the lower ₹20 lakh limit applies to your total turnover.

Service providers must register once their aggregate turnover crosses ₹20 lakh in a year (₹10 lakh in Manipur, Mizoram, Nagaland and Tripura). This covers consultants, freelancers, agencies, tutors, contractors and every other service business.

Unlike goods, services sold to clients in other states do not force you to register below the limit. A designer in Pune billing clients in Delhi and Bengaluru can stay unregistered until total turnover crosses ₹20 lakh.

Sellers of goods must register once turnover crosses ₹40 lakh a year in most states, or ₹20 lakh in Telangana, Puducherry, Uttarakhand, Meghalaya, Sikkim and Arunachal Pradesh. The ₹40 lakh limit applies only if all sales are within your state. A seller who ships goods to even one customer in another state must register from the first sale, whatever the turnover.

No. Below the registration limit, GST is optional for most small businesses. But registration is compulsory from the first rupee of turnover if you:

• sell goods to another state
• sell goods through an e-commerce platform in more than one state, or across state lines
• must pay tax under reverse charge, for example as a registered tenant renting commercial property from an unregistered landlord
• are a casual taxable person, such as a stall at an exhibition in another state
• supply goods or services on behalf of others as an agent, or work as an input service distributor

Many businesses below the limit register voluntarily, because business customers want a GSTIN on the invoice so they can claim input tax credit. If most of your customers are consumers who cannot claim credit, staying unregistered lets you price without adding GST on top.

If your turnover is below ₹20 lakh, you do not need GST registration for services or goods sold within your state, unless one of the compulsory cases above applies. You cannot charge GST on your bills without a GSTIN; collecting "GST" without registration is an offence.

If your turnover is likely to cross the limit during the year, apply within 30 days of crossing it. Tax is due on sales from the date you become liable to register.

Not always. Since 1 October 2023, a small seller can sell goods on Flipkart, Amazon, Meesho and similar platforms without GST registration, if turnover is below the state's registration limit, all sales are within one state and no goods go to other states. The seller needs a PAN and an enrolment number from the GST portal, which the platform asks for in place of a GSTIN.

To sell to buyers across India through the platform, you need full GST registration.

No. Udyam (MSME) registration does not need a GSTIN if your business is not required to register for GST. The same applies to a current account and a Mudra loan: banks accept other business proof, such as the Udyam certificate or a shop and establishment licence. If your business is already GST-registered, you must give the GSTIN.

GST registration is free and done online on gst.gov.in. No fee is charged by the government; consultants charge only for their service.

From 1 November 2025, applicants whose monthly output tax on sales to registered businesses is ₹2.5 lakh or less can opt for registration within 3 working days of Aadhaar authentication (Rule 14A). Other low-risk applicants also get registration in 3 working days under Rule 9A. Applications sent for physical verification take longer.

Freelancers must register for GST once their total income from services crosses ₹20 lakh in a year (₹10 lakh in four north-eastern states). Income from foreign clients counts toward this limit.

Once registered:

A freelancer earning ₹25 lakh a year, all from foreign clients, must register because turnover is above ₹20 lakh, but with an LUT pays no GST on that income.

GST has three main rates since 22 September 2025: 5%, 18% and 40%. The old 12% and 28% slabs were removed. Some items are exempt, and gold has a special 3% rate.

The rate depends on the item's HSN code (goods) or SAC code (services), not on the size of your business. Restaurants charge 5% but cannot claim input tax credit.

To add GST, multiply the price by (1 + rate). To find the GST inside a GST-inclusive price, multiply it by rate ÷ (100 + rate).

Within your state, the GST splits equally into CGST and SGST: ₹900 + ₹900 on the example above. To another state, the whole ₹1,800 is IGST. Do the sums instantly in the GST Calculator.

Input tax credit (ITC) means the GST you paid on business purchases is deducted from the GST you collect on sales, so you pay tax only on the value you add.

A registered trader in one month:

ITC is allowed only when all of these hold: you have the supplier's tax invoice, you have received the goods or services, the invoice appears in your GSTR-2B, and the supplier has paid the tax. You must also pay the supplier within 180 days, or reverse the credit.

ITC is blocked on cars (with exceptions such as dealers and driving schools), food and catering, beauty and health services, club memberships, construction of your own building, and anything for personal use.

The composition scheme lets a small business pay GST at a flat 1%–6% of turnover and file one quarterly payment and one annual return, instead of monthly returns. In exchange, you cannot charge GST to customers, cannot claim input tax credit and cannot sell to other states.

It suits a shop, restaurant or local service business that sells mostly to consumers. It does not suit a business whose customers are registered businesses, because they cannot claim credit on your bills.

A goods business under the scheme may also earn service income of up to 10% of turnover or ₹5 lakh, whichever is higher. Opt in on Form CMP-02 before the financial year starts.

A kirana store with ₹60 lakh annual turnover pays ₹60,000 a year (₹15,000 a quarter) under the scheme. That comes out of its own margin, because a composition dealer issues a bill of supply and cannot add GST.

Ice cream, pan masala and tobacco manufacturers cannot opt in. Since 1 October 2023, composition dealers can sell goods through e-commerce platforms, but cannot supply services through them.

A regular GST taxpayer files GSTR-1 (sales) and GSTR-3B (summary and payment) every month, or every quarter under the QRMP scheme if turnover is up to ₹5 crore, plus an annual return.

Since the July 2025 tax period, the tax liability in GSTR-3B is auto-filled from your GSTR-1 and cannot be edited, so correct mistakes through GSTR-1A before filing GSTR-3B.

Filing GSTR-3B or GSTR-1 late costs ₹50 a day (₹20 a day for a nil return), plus 18% a year interest on tax paid late.

Interest is charged only on tax paid in cash, not on tax set off against input tax credit. ₹50,000 of tax paid 30 days late costs ₹740 in interest; filing 15 days late adds a ₹750 late fee.

Returns more than three years past their due date can no longer be filed on the portal, a rule that applies from the July 2025 tax period.

Residential rent is exempt from GST when you rent a home to live in. Commercial rent attracts 18% GST.
