Goods and Services Tax (GST) has been one of the most transformative tax reforms in India’s history. Introduced on July 1, 2017, GST aimed to unify the complex web of indirect taxes into a single, transparent, and streamlined system. While GST simplifies taxation in the long term, the initial registration and ongoing compliance requirements can be daunting for many businesses — especially startups and MSMEs.

As Chartered Accountants, we’ve worked with hundreds of businesses, helping them navigate the nuances of GST with confidence. In this blog, we’ll walk you through everything you need to know about GST registration and compliance support, demystify the process, and explain how professional assistance can save your business time, money, and legal trouble.

What is GST Registration?

GST registration is a legal obligation for businesses whose aggregate turnover exceeds the prescribed threshold limits. Upon registration, businesses receive a GSTIN (Goods and Services Tax Identification Number), which is essential for collecting GST from customers, availing input tax credit (ITC), and filing returns.

Threshold Limits for GST Registration (as of 2025)

Note: Voluntary registration is also allowed below these thresholds.

Why Is GST Registration Important?

1. Legal Recognition of your business under GST law

2. Authorization to Collect GST and pass on tax benefits to customers

3. Eligibility for Input Tax Credit, reducing your overall tax liability

4. Improved Business Credibility with clients, vendors, and banks

5. Mandatory for E-commerce Sellers, exporters, and interstate suppliers
   
   

Documents Required for GST Registration

• PAN of the business or applicant

• Aadhaar card

• Proof of business registration (Partnership Deed / Certificate of Incorporation)

• Address proof of business (Electricity bill / Rent agreement)

• Bank account statement or canceled cheque

• Digital Signature Certificate (for companies and LLPs)

2. Payment of GST Liabilities

• By the 20th of the following month (for regular taxpayers)

• Includes IGST, CGST, SGST based on transaction type
  
  
  

3. Reconciliation of ITC

• Matching purchase invoices with GSTR-2B

• Rectifying mismatches to avoid ITC denial and penalties
  
  
  

4. Responding to Notices

• GST officers may issue Notices (SCNs) for non-compliance, mismatches, late filing, etc.

• Timely response and documentation are crucial
