GST Registration

What to know

To complete your GST registration, you need several key documents. You will need a PAN Card for the applicant or authorized signatories. A passport-sized photo of the owner is also required. You must provide a valid phone number and email ID. Proof of business address is essential. This can be a rent/lease agreement, property tax receipt, municipal khata copy, or an electricity bill. Bank account details, like a cancelled cheque or bank statement, are also necessary. The specific documents needed change based on the business structure. This includes a sole proprietorship, partnership firm, or company, as the Goods and Services Tax Network outlines. For example, a partnership firm needs a partnership deed. A company needs a Certificate of Incorporation and a Board Resolution. These documents ensure proper verification and compliance with GST rules.

Keep the business banking separate from the personal from day one, because the same paperwork is what a lender or an issuer will ask for later. A dedicated card makes the input-credit trail far easier to reconcile — see best business credit cards.

The time for GST registration changes, but recent updates aim for faster processing. The Central Goods and Services Tax (Fourth Amendment) Rules, 2025, are effective November 1, 2025. They let GST registration be approved electronically within three working days. This quick process uses data-based risk checks. Standard processing can take up to seven working days if a GST officer raises a query. After submitting Form GST REG-01, applicants get a reference number by email and mobile. They then complete the second part of the form. They upload documents and wait for the Certificate of Registration. This new rule helps businesses start operations faster. It reduces delays often seen in manual verification processes. The government aims to improve ease of doing business through these changes. Businesses can track their application status online using the reference number provided.

GST registration turnover limits differ greatly by state and business type. For most goods suppliers, the annual aggregate turnover limit is ₹40 lakh. However, for service providers, this limit is ₹20 lakh. Special category states have lower limits. These include North-Eastern states, Jammu & Kashmir, Himachal Pradesh, and Uttarakhand. Their limits are often ₹10 lakh or ₹20 lakh. Certain businesses must register no matter their turnover. This includes e-commerce sellers, agents of suppliers, and input tax distributors. Those falling under the reverse charge mechanism also must register. Non-resident taxable persons and casual taxable persons have specific registration needs. For instance, a non-resident taxable person must register for GST even if their turnover is zero. They must do this before starting any business operations in India. This ensures all types of businesses comply with the tax system.

GST is only one of the liabilities a registered business carries. Income tax on the profits is separate, and once the liability is large enough it has to be paid through the year rather than at the end of it — estimate both with the income tax calculator and the advance tax calculator.
