GST Registration Guide for Indian Businesses (2026)
Who needs GST, what the thresholds and slabs are, the documents required and how to register — explained simply for founders and SMEs.
Do you need GST registration?
Registration is mandatory once your turnover crosses the prescribed threshold (different for goods, services and special-category states), and for some categories like inter-state supply and ecommerce from the start. Voluntary registration can also help you claim input tax credit.
Understand the slabs
GST in India has slabs of 0%, 5%, 12%, 18% and 28% depending on the product or service. Knowing your slab is essential for pricing and invoicing correctly.
Documents you need
Typically PAN, proof of business, address proof, bank details and photographs. Keep them ready before you start the application.
How to register
Apply on the GST portal, submit documents, complete verification and receive your GSTIN. Many businesses use a CA to avoid errors that delay approval.
After registration
File the right returns on time (GSTR-1, GSTR-3B etc.), maintain proper invoices and claim input tax credit correctly. The BharatOS GST Helper explains each step so you stay compliant.
