Understanding GSTR-2B: A Comprehensive Guide for Businesses (2026 Edition)
Introduction
GSTR-2B has become one of the most important tools in GST compliance for businesses in India. It is a monthly auto-generated Input Tax Credit (ITC) statement that helps taxpayers determine how much ITC they can claim accurately.
Unlike earlier systems, GSTR-2B provides a fixed (snapshot) of ITC, making reconciliation easier and reducing errors in GST filings.
What is GSTR-2B?
GSTR-2B is a static, auto-drafted statement that shows eligible and ineligible ITC for a specific tax period. It is generated based on data filed by suppliers in:
- GSTR-1
- GSTR-5 (non-resident taxpayers)
- GSTR-6 (Input Service Distributor)
It includes invoice-wise details of inward supplies and ITC availability.
👉 Once generated, GSTR-2B does not change, even if suppliers later update their returns.
