New Income Tax Audit Amendments 2026–27
Full Breakdown of Rules, Transition & Compliance Updates
📌 Introduction
Assessment Year 2026–27 marks a pivotal transition in India’s tax landscape. It represents the shift from the long-standing Income-tax Act, 1961 to the newly implemented Income Tax Act, 2025. While the new framework has officially come into effect from April 2026, tax audits for income earned during FY 2025–26 continue to follow the provisions of the old law.
This overlap creates a unique compliance situation for taxpayers and professionals, where understanding the distinction between current and future rules becomes critical. This guide simplifies all key amendments, helping you stay compliant and avoid costly errors.
⚠️ Key Clarification

- ✔ Tax audit must be filed using Forms 3CA / 3CB / 3CD
- ✔ New Form 26 is NOT applicable for AY 2026–27
- ✔ Form 26 applies from Tax Year 2026–27 onwards
