GST Registration: A Practical Guide for New Businesses

For many new businesses, GST registration is one of the first formal steps after choosing a business structure. Some businesses are required to register from day one, others only once they cross a turnover limit, and some choose to register voluntarily because their customers expect it. Understanding which group you fall into helps you avoid both unnecessary compliance and penalties for registering late.

When registration is based on turnover

Most businesses become liable to register once their aggregate turnover in a financial year crosses the threshold that applies to them. Currently, the threshold is generally higher for businesses that supply only goods than for those that supply services, and lower limits apply in certain special category states. Aggregate turnover is usually calculated on an all-India basis for the same PAN, and includes taxable, exempt and export supplies.

Because the thresholds and the list of special category states can change, check the current figures for your state and type of supply before relying on them. It also helps to track turnover monthly, so you know well in advance when you are approaching the limit.

When registration is compulsory regardless of turnover

Certain businesses are generally required to register even if their turnover is small. Common examples include:

• Businesses making inter-state taxable supplies of goods, subject to limited exceptions
• Sellers supplying goods through e-commerce platforms that collect tax at source
• Casual taxable persons, such as those setting up a temporary stall at an exhibition in another state
• Persons required to pay tax under the reverse charge mechanism
• Input service distributors and persons required to deduct or collect tax at source under GST
• Non-resident taxable persons making taxable supplies in India

Service providers selling through online platforms, and small suppliers of services across state lines, have seen specific relaxations in recent years. The exact scope of these relaxations should be confirmed against the current rules.

Should you register voluntarily?

A business below the threshold can choose to register. The main advantages are that you can claim input tax credit on your purchases and that business customers who want to claim credit themselves may prefer to buy from registered suppliers. The trade-off is that once registered, you must charge GST on taxable sales, issue proper tax invoices and file returns on time, even in months with no activity.

If most of your customers are individual consumers who cannot claim credit, voluntary registration may raise your effective prices without much benefit. If most are businesses, it often makes commercial sense. Think through your customer base before deciding.

Documents to prepare

The exact list depends on the type of business, but you will generally need:

• PAN of the business, or of the proprietor in the case of a sole proprietorship
• Identity and address details of the proprietor, partners or directors, along with photographs
• Constitution documents, such as a partnership deed, LLP agreement or certificate of incorporation
• Proof of the principal place of business, such as an electricity bill or property tax receipt, plus a rent agreement or consent letter from the owner if the premises are not owned
• Bank account details, such as a cancelled cheque or bank statement
• Authorisation for the person signing the application, where applicable
• A digital signature certificate for companies and LLPs

Mismatches between names, addresses and PAN records are one of the most common reasons for queries, so check that details are consistent across all documents before you apply.

How the application process works

1. Part A: you enter basic details such as PAN, mobile number and email on the GST portal. After verification, a temporary reference number is generated.
2. Part B: you complete the full application, including business details, promoters, place of business, goods or services supplied and bank details, and upload documents.
3. Authentication: the application is signed and, where opted for, Aadhaar authentication is completed. Applicants who do not opt for authentication, or who are flagged on risk parameters, may be subject to physical verification of premises or biometric verification at a facilitation centre.
4. Review by the officer: the tax officer may approve the application or raise a query. Queries must be answered within the prescribed time, or the application may be rejected.
5. Registration certificate: once approved, a GSTIN is issued and the certificate can be downloaded from the portal.

Timelines are set by the rules and depend on verification and any queries raised. The final decision rests with the tax authority.

Composition scheme: a simpler option for some

Small businesses within a prescribed turnover limit may be able to opt for the composition scheme. It generally allows tax to be paid at a lower fixed rate on turnover with simpler return filing, but composition taxpayers cannot collect GST from customers or claim input tax credit, and certain businesses and supplies are excluded. It suits some local traders and manufacturers but not businesses that sell mainly to other registered businesses.

What changes after you are registered

• Your GSTIN should be displayed at your place of business and shown on invoices.
• Invoices must contain the details prescribed under GST rules.
• Returns must be filed for every period, including nil returns when there is no activity. Late filing generally attracts late fees and interest.
• Changes to address, partners, directors or business activity must be updated through an amendment application.
• If you close the business, registration should be formally cancelled rather than left inactive.

Before you proceed

GST thresholds, compulsory registration categories, verification procedures and return requirements are revised from time to time through notifications and circulars. Confirm the current position on the official GST portal or seek advice specific to your business before applying.
