Every registered business under the Goods and Services Tax (GST) law in India has a responsibility to maintain compliance. One of the most crucial annual compliances is filing the GSTR-9 – the annual GST return.

What is GSTR-9?

GSTR-9 is the annual GST return to be filed once every financial year by registered taxpayers. It consolidates the details of outward supplies, inward supplies, input tax credit (ITC), and tax paid as declared in monthly/quarterly returns (GSTR-1, GSTR-3B, etc.) during the year.

It ensures accurate reconciliation of GST data and helps the government monitor tax compliance.

As per GST law, the following taxpayers must file GSTR-9:

• All regular taxpayers registered under GST.
• Businesses with aggregate turnover exceeding ₹2 crore (mandatory).
• Businesses with turnover below ₹2 crore (optional, but recommended for compliance score).

Exempt from Filing GSTR-9

• Composition taxpayers (they file GSTR-9A instead).
• Casual taxpayers.
• Non-resident taxpayers.
