Brief note on broad or qualitative changes proposed:

- Introduction of “Tax Year” terminology replacing “Assessment Year”.

- Enhanced reporting of transactions covered under sections 185, 186 and 188 of Income Tax Act, 2025.

- Redundant sections 40(A)(5)(c), 40(A)(6), 40A(8) of I T Act, 1961 are removed since these sections have already been omitted from the Act long back. Also, these sections do not find place in the new ITA, 2025.

- Since form 6B has not been amended for many years, therefore, certain items from Form 3CD have been borrowed to make the form more relevant and necessary changes have been made.

- Simplified and standardized tabular formats have been used wherever necessary.

Challenges and Solutions:

Since earlier Form 6B had not been revised for many years, the structure has now been updated using the format of Form 3CD, introducing simplified tabular reporting. Presently even though Form No. 6B is e-form, only Special Auditors certificate is uploaded online and Special Audit Report along with annexures is being submitted through e-mail or offline mode. In this regard, simplified and standardized tabular formats have been used wherever necessary. Therefore, Special Audit Report along with annexures also can be submitted through online mode in future.

Common Changes Made Across Forms:

1. To make Forms system-friendly and enable e-filing and uploading, certain anomalies found due to grouping of Name, Address and PAN have been separated into different boxes.
2. Assessment / Financial / Previous year or years have been replaced with Tax year or years, wherever appearing in the Form/Annexure.
3. Sections, Clauses and Schedules changed as per the Income-tax Act, 2025.
4. Currency symbol “Rs.” has been replaced with “₹”.
