Introduction

In the GST ecosystem, Input Tax Credit (ITC) is one of the most powerful tools available to businesses to reduce their tax burden. However, with increasing scrutiny, data analytics, and strict compliance rules, claiming ITC in 2026 is no longer straightforward.

Many businesses lose significant money due to incorrect ITC claims, mismatches, or non-compliance, leading to GST notices, penalties, and blocked credits.

This complete guide on ITC rules for 2026 will help you understand eligibility, conditions, restrictions, and practical strategies to maximize ITC while staying fully compliant.

1. What is Input Tax Credit (ITC)?

Input Tax Credit (ITC) means the tax that a business pays on purchases can be set off against its output GST liability.

🔹 Simple Example:

• GST paid on purchase = ₹10,000
