How Does GST Registration Work: A Complete Guide for Businesses

GST registration is the process by which a business obtains a unique Goods and Services Tax Identification Number (GSTIN) from the tax authorities. Under the Central Goods and Services Tax Act, 2017, any business whose aggregate turnover in a financial year exceeds ₹40 lakh (₹20 lakh for special category states) must register. For businesses engaged exclusively in the supply of goods, the threshold is ₹40 lakh; for service providers, it is ₹20 lakh. Additionally, certain categories of suppliers must register regardless of turnover, including persons making inter-state taxable supply, casual taxable persons, non-resident taxable persons, agents of a principal, and e-commerce operators.

The registration requirement applies to the supplier of goods or services. If you are a manufacturer, trader, or service provider, you must evaluate your turnover in the preceding financial year. The aggregate turnover includes all taxable supplies, exempt supplies, exports, and inter-state supplies. If your turnover crosses the threshold, you must apply within 30 days from the date you become liable. Failure to register can result in penalties and interest.

The GST registration process works entirely online through the GST portal (www.gst.gov.in). You do not need to visit any office. The process involves the following steps:

1. Access the portal: Go to the GST portal and click on "Services" > "Registration" > "New Registration".
2. Enter basic details: Provide your PAN, mobile number, and email address. You will receive a Temporary Reference Number (TRN) via SMS and email.
3. Complete the application: Log in using the TRN and fill Part B of the application. This includes business details, promoters/partners/directors information, principal place of business, additional places of business, bank account details, and the goods or services you supply.
4. Upload documents: Attach scanned copies of required documents such as PAN card, Aadhaar card, proof of business registration (e.g., Certificate of Incorporation), address proof, bank statement or cancelled cheque, and photographs of promoters.
5. Submit and verify: Submit the application using a Digital Signature Certificate (DSC) or Electronic Verification Code (EVC). For companies and LLPs, DSC is mandatory.
6. ARN generation: Upon successful submission, an Application Reference Number (ARN) is generated. You can track the status using this ARN.

The GST officer will verify the application. If no discrepancies are found, the registration certificate is issued within 7 working days. If the officer requires additional information, they will issue a notice, and you must respond within 7 working days.

The documents required depend on the type of business entity. For all entities, the following are commonly needed:

• PAN card of the business or the proprietor
• Aadhaar card of the proprietor or partners/directors
• Proof of business registration: Certificate of Incorporation (for companies), Partnership Deed (for partnerships), or any other registration document
• Address proof of the principal place of business: Electricity bill, property tax receipt, rent agreement, or municipal khata copy
• Bank account details: First page of bank passbook or a cancelled cheque
• Photographs of the proprietor, partners, or directors
• Digital Signature Certificate (for companies and LLPs)

For a proprietorship, the PAN of the proprietor is used. For a partnership or LLP, the PAN of the entity is required. If the business is a company, the PAN of the company is needed. The documents must be in PDF or JPEG format, and the file size should not exceed 1 MB per document.

The GST registration process is designed to be completed within 7 working days from the date of submission of the complete application. However, this timeline can extend if the GST officer raises queries. In practice, most registrations are processed within 2 to 3 weeks. There is no fee for applying for GST registration. The entire process is free of cost on the GST portal.

If you engage a tax consultant or a chartered accountant to assist with the application, they may charge a professional fee. This fee varies depending on the complexity of your business structure and the volume of documents. Typically, the professional fee ranges from ₹500 to ₹5,000. You should confirm the fee before engaging a professional.

Once your GST registration is approved, you will receive a GST Registration Certificate in Form GST REG-06. This certificate contains your GSTIN, which is a 15-digit alphanumeric number. The first two digits represent the state code, the next ten digits are your PAN, the thirteenth digit is the entity code (based on the number of registrations in a state), the fourteenth digit is "Z" by default, and the last digit is a checksum.

After registration, you must:

• Display the GSTIN on your business premises
• Issue tax invoices with the GSTIN
• File GST returns regularly (monthly or quarterly, depending on your turnover)
• Maintain proper books of accounts
• Collect GST from customers and deposit it with the government

You are also required to file a nil return even if you have no business activity during a period. Failure to file returns can lead to cancellation of registration and penalties.

If your business is approaching the turnover threshold or you are starting a new venture, you should assess your liability for GST registration. The process is straightforward, but errors in documentation or application can cause delays. Consult a qualified chartered accountant or tax professional to ensure your application is complete and accurate.
