What is the GST registration threshold for small businesses?

The GST registration threshold for goods suppliers is ₹40 lakh annual turnover (₹20 lakh for special category states). For service providers, the threshold is ₹20 lakh (₹10 lakh for special category states). However, certain businesses must register regardless of turnover: interstate suppliers, e-commerce sellers, importers, casual taxable persons, and those making supplies under reverse charge.

What is a GSTIN and how many digits does it have?

GSTIN (Goods and Services Tax Identification Number) is a unique 15-digit alphanumeric code assigned to every GST-registered business. The format is: 2-digit state code + 10-digit PAN + 1-digit entity number + 1 'Z' + 1 check digit. For example: 07AAAAA0000A1Z5 (Delhi). The GSTIN must be mentioned on all tax invoices.

What GST returns do I need to file after registration?

The main GST returns are: (1) GSTR-1: Monthly/quarterly return of outward supplies (sales). Filed by the 11th or 13th of the following month. (2) GSTR-3B: Monthly summary return of sales, ITC and tax payment. Filed by the 20th of the following month. (3) GSTR-9: Annual return, filed by 31 December. (4) Composition dealers file GSTR-4 annually and CMP-08 quarterly.

What is the GST Composition Scheme?

The Composition Scheme allows small businesses with turnover up to ₹1.5 crore (₹75 lakh for services) to pay GST at a flat rate (1% for manufacturers, 5% for restaurants, 6% for service providers) without the burden of monthly return filing. Composition dealers cannot claim input tax credit and cannot sell across state borders.

Can I have multiple GSTINs?

Yes. If your business operates in multiple states, you need a separate GSTIN for each state. A business can also obtain multiple GSTINs within the same state if it has multiple business verticals (different types of businesses). Each GSTIN requires separate registration, separate accounts and separate return filing.

What happens if I don't register for GST when mandatory?

Operating without mandatory GST registration is an offence under the GST Act. Penalties include: (1) Penalty of 10% of the tax amount (minimum ₹10,000). (2) In case of deliberate evasion: 100% of the tax amount or ₹10,000, whichever is higher. (3) Demand and recovery of unpaid tax plus interest at 18% per annum.

What is Input Tax Credit (ITC) and how does it benefit me?

Input Tax Credit (ITC) allows you to claim credit for GST paid on your business purchases against your GST liability on sales. For example: If you pay ₹18,000 GST on raw materials and collect ₹30,000 GST on sales, you only pay ₹12,000 net to the government. This prevents cascading of taxes and reduces the effective tax burden.

How long does GST registration take?

After filing the GST REG-01 application, the GST officer has 7 working days to approve or raise queries. If Aadhar OTP authentication is done at the time of application, approval can come within 3 working days. Total time from document submission to GSTIN is typically 3–7 working days with our expert assistance.
