Who needs GST, which documents to keep ready, and how long registration actually takes — a practical guide for first-time business owners.
GST registration is one of the first compliance steps for most Indian businesses. Whether you sell products online, provide services across states, or simply cross the turnover threshold, a GSTIN is your ticket to legally operating at scale.
Who needs registration? Businesses with turnover above ₹40 lakh for goods (₹20 lakh in special-category states), service providers above ₹20 lakh, e-commerce sellers regardless of turnover, and anyone doing inter-state supplies.
Documents you should keep ready: PAN and Aadhaar of the proprietor or partners, photographs, proof of business premises (electricity bill or rent agreement), a bank statement or cancelled cheque, and your business registration certificate if you are a company or LLP.
The actual filing takes minutes on the portal — the waiting is in the verification. With Aadhaar authentication enabled, most clean applications receive their GSTIN within 3-7 working days. Departments raise queries when addresses don't match or premises proof is old, so professional review before filing saves weeks.
Once registered, remember the monthly rhythm: GSTR-1 by the 11th and GSTR-3B by the 20th (for monthly filers). Missing these attracts ₹50/day late fee per return — a completely avoidable cost.
