GST Registration in India: Documents, Fees & Online Application Guide

Goods and Services Tax (GST) has become an essential part of India’s taxation system since its introduction. For every business that crosses the prescribed turnover limit or engages in interstate supply, GST registration in India is mandatory. Without proper registration, businesses cannot legally collect GST from customers or claim input tax credits.

If you are planning to start a business or expand an existing one, understanding the complete process of GST registration, required documents, fees, and online application is crucial. This guide by Mohit S. Shah & Co. will help you navigate the process step by step.

What is GST Registration in India?

GST registration is the process by which a business obtains a unique GSTIN (Goods and Services Tax Identification Number). This 15-digit number is issued by the government after successful registration. It acts as a recognition that the business is authorized to collect GST and avail benefits under GST laws.

Many new business owners are confused about whether GST is applicable to them. The general rule is that any business with turnover above the threshold limit (₹20 lakh for services and ₹40 lakh for goods, with variations for certain states) must register.

If you are unsure about eligibility, it is best to consult a professional chartered accountant in Mumbai who can guide you through the process.

Who Should Apply for GST Registration in India?

Not all businesses require GST registration, but several categories are mandated to register regardless of turnover.

You should apply for GST number in India if you fall into one of these categories:

  • Businesses with turnover above the prescribed threshold.

  • E-commerce sellers or operators.

  • Businesses supplying goods or services across state borders.

  • Agents or input service distributors.

  • Casual taxable persons or non-resident taxable persons.

  • Businesses required to pay tax under reverse charge mechanism.

Documents Required for GST Registration in India

Applying for GST requires careful preparation of documents. Incorrect or incomplete documents are one of the main reasons for application rejection. Below is the checklist:

  1. PAN Card of Business or Applicant

  2. Proof of Business Registration (Partnership deed, Incorporation certificate, etc.)

  3. Identity Proof of Promoters/Partners (Aadhar, PAN, Passport, Voter ID)

  4. Address Proof of Promoters/Partners

  5. Business Address Proof (Electricity bill, rent agreement, NOC from owner if rented)

  6. Bank Account Details (Cancelled cheque or bank statement)

  7. Photographs of Promoters/Owners

  8. Digital Signature Certificate (DSC) for companies and LLPs

Preparing these documents in advance can save you time and avoid unnecessary delays.

Step-by-Step Online Application Process

Though GST registration is applied online, many businesses face challenges due to technical issues, document mismatches, or improper filings. Here’s the step-by-step process simplified:

Step 1: Prepare Documents

Gather all the documents mentioned above.

Step 2: Submit Application Online

Fill in the GST REG-01 form with business details, promoter details, and bank details.

Step 3: Verification by GST Authorities

Authorities will review your application and request additional documents if required.

Step 4: Issue of GSTIN

Once approved, you will receive a GSTIN and GST registration certificate.

This process might sound straightforward, but in reality, many applications get rejected. That is why consulting professionals like Mohit S. Shah & Co., a trusted CA firm in Mumbai, can ensure a smooth approval without delays.

GST Registration Fees in India

Government charges for GST registration are zero – meaning there is no official government fee for registering under GST. However, professional charges may apply if you hire a consultant or a chartered accountant firm in Mumbai to handle the process.

Considering the complexities involved, hiring a CA is a smart investment. Mistakes in application can lead to rejections and compliance issues, which may cost much more than professional fees.
