Introduction
GST Registration is the process by which a business or individual obtains a unique 15-digit Goods and Services Tax Identification Number (GSTIN) from the Government of India. Under the GST Act, 2017, any business whose aggregate turnover exceeds the prescribed threshold must register for GST. A2Z Accounting & Tax Firm provides end-to-end online GST registration services starting at ₹999, with GSTIN delivery in 3–7 business days.
GST (Goods and Services Tax) is India's unified indirect tax system that replaced multiple taxes like VAT, Service Tax, Excise Duty, and CST. Registration under GST is mandatory for businesses exceeding turnover thresholds, inter-state suppliers, e-commerce operators, and entities making taxable supplies.
What is GST Registration?
GST Registration is the legal process of enrolling a business under the Goods and Services Tax regime with the Central and State tax authorities. Upon successful registration, the government assigns a 15-digit GSTIN (Goods and Services Tax Identification Number) which is mandatory for collecting tax, claiming Input Tax Credit (ITC), and filing GST returns.
The GSTIN structure is: 22AAAAA0000A1Z5 — where the first 2 digits represent the state code, the next 10 digits are the PAN, followed by entity number, alphabet, and check digit.
GST Registration is governed by Section 22 to Section 30 of the CGST Act, 2017 and the corresponding state GST Acts.
Why is GST Registration Important?
- Legal Compliance — Operating without GST registration when liable is a punishable offence under the GST Act with penalties up to 100% of the tax due.
- Input Tax Credit (ITC) — Only registered businesses can claim Input Tax Credit on purchases, reducing their overall tax burden.
- Interstate Business — GST registration is mandatory for any business making inter-state supplies, regardless of turnover.
- E-commerce Selling — Platforms like Amazon, Flipkart, and Meesho require sellers to have a valid GSTIN before listing products.
- Government Tenders — Most government contracts and tenders require a valid GSTIN as a mandatory eligibility criterion.
