What Is a GSTIN and Why Does It Matter?
GSTIN (Goods and Services Tax Identification Number) is a unique 15-character alphanumeric number assigned to every business registered under India's Goods and Services Tax regime. Introduced along with GST on July 1, 2017, the GSTIN replaced the earlier VAT TIN, Service Tax Number, and Central Excise Registration under a unified national tax identity.
Every business with an annual turnover exceeding ₹20 lakh (₹10 lakh in special category states) must obtain a GSTIN. Businesses making inter-state supplies, e-commerce operators, TDS/TCS deductors, and casual taxable persons also require mandatory registration irrespective of turnover.
The GSTIN is critical for Input Tax Credit (ITC) — the mechanism that prevents cascading taxation by allowing businesses to offset tax paid on purchases against tax collected on sales. To claim ITC, your supplier's GSTIN must be active, correctly stated on the invoice, and the supplier must file their GSTR-1 returns diligently.
