The indirect taxation system in India has changed with the introduction of the Goods and Services Tax (GST), which has established a single tax system. GST registration is also among the most important statutory compliances of any business in India. As a startup, trader, manufacturer, service provider, or online seller, it is necessary to understand GST registration to conduct business legally.
This blog explains the registration of a business under GST in India in detail, including eligibility, types, documents, the process, benefits, penalties, and most pitfalls.
What is GST Registration?
A business is registered under the Goods and Services Tax Act and is assigned a GST Identification Number (GSTIN). A GSTIN is a 15-digit unique identification number for all registered taxpayers.
After registration, the business is legally empowered to collect GST on behalf of its customers, claim input tax credit, file GST returns, and comply with open-ended GST laws in India.
Significance of GST Registration to Business
Registration for GST is critical to ensuring that businesses operate within the law and that their operations run smoothly.
It not only gives the business legal status as a registered supplier, but also enables tax to be collected on behalf of the government, allows input tax credit to be claimed, boosts credibility with customers and vendors, and enables smoother inter-state trade.
In the absence of GST registration, businesses can be penalised, face legal cases, and be deprived of business opportunities.
Who is to be Registered Under GST?
Some businesses are required to register for GST regardless of their turnover.
Companies that have an aggregate annual turnover of Rs.40 lakh or more in the case of goods and Rs.20 lakh or more in the case of services will be required to register under GST. In the case of special category states, the threshold is smaller.
Registration under GST is also mandatory for businesses that engage in inter-state supply, e-commerce merchants, individuals who supply via online marketplaces, casual taxable individuals, non-resident taxable individuals, and other persons who need to deduct or collect tax under GST.
A business with less than the threshold limit can also choose to apply voluntary GST registration so as to enjoy tax incentives and build market reputation.
Types of GST Registration in India
GST law offers various registrations depending on the nature and form of business.
- Regular GST Registration: The most common type of registration for manufacturers, traders, and service providers is this one. Companies in this category are required to pay GST at the relevant rates and submit frequent returns.
- Registration of Composition Schemes: The composition scheme can be used by small businesses with a turnover of up to Rs.1.5 crore. In this scheme, GST is paid at a lower fixed rate, with no input tax credit available to the business.
- Registration of casual taxable persons: This registration applies to business ventures that are usually temporary in operation in a different state, such as trade fairs, exhibitions, or seasonal businesses.
- Registration of a non-resident taxable person: This applies to a foreign individual or entity that supplies goods or services in India without a permanent place of business.
Document Needed for GST Registration
The successful registration of the GST requires proper documentation.
For business information, PAN card, certificate of incorporation, or partnership deed, address evidence of the business location is required. For owners, partners, or directors, PAN cards, Aadhaar cards, photographs, and address proof are required.
Details of the bank accounts, including cancelled cheques or bank statements, are also needed. Businesses and LLPs are required to submit a certificate of digital signature, and individuals can check it via an Aadhaar OTP.
Step-by-Step GST Registration Process in India
- GST registration is a web-based process conducted via the GST portal.
- Part A of the registration form is then completed by the applicant with basic information such as PAN, email ID, and mobile number.
- Once OTP verification is complete, Part B of the application is filled with business information, promoter information, bank information, and documents are uploaded.
- After the application has been received, the GST department confirms the information.
- The GSTIN and registration certificate are electronically issued in case they are found satisfactory.
- This process typically takes 3 to 7 working days.
Advantages of GST Registration
Registration for GST offers a number of benefits to businesses, regardless of their size.
GST can be collected by registered businesses, and customers can claim input tax credits on purchases. It makes it easy to trade among states and sell online. GST registration also enhances a business’s credibility, making it easier to secure loans and gain clients, as well as build long-term trust.
For startups, GST registration provides a solid foundation for further development and compliance.
Penalties on Non-Registration under GST
Failure to register under GST, where necessary, will be heavily penalised.
A fine of 10 per cent of the tax amount to pay or Rs. 10,000, whichever is greater, can be paid. The punishment for deliberate tax evasion can include 100 per cent of the tax liability, plus interest and legal repercussions.
Early GST registration will protect businesses from unwarranted financial and legal risks.
Common Mistakes to Avoid During GST Registration
Some common errors include an incorrect business address, a lack of harmonisation of PAN and Aadhaar information, a wrongly selected business constitution, invalid bank information, and a wrong GST scheme. This results in delays, notice or rejection of the application due to such mistakes.
Professional assistance also guarantees correct filing and easy approval.
Conclusion
Online GST registration is not just a tax formalism; it is a mandatory legal requirement for business operations in India. It is mandatory, enhances credibility and offers numerous tax advantages. Whether it is optional or compulsory, registering for GST on time safeguards the business against fines and enables sustainable growth.
To make GST registration and compliance hassle-free, it is always a good idea to seek the services of professionally qualified lawyers.
