New Tax Audit Form 26 Expands Stock Reporting Requirements in 2026-27

Tax Audit 2026-27 – Quantitative Details of Stock, Purchases & Sales – Scope Significantly Expanded

Under the existing Form 3CD, Tax Auditors are required to report quantitative details of principal items of Purchases, Sales, and Opening & Closing Stock for both trading and manufacturing entities. However, this reporting was limited to quantity alone, value was not required.

The New Tax Audit Form No. 26, applicable from Tax Year 2026-27, changes this fundamentally.

The scope has now been extended to include the value of principal items of Purchases, Sales, and Stock — in addition to quantity as per Clause 53 of New Tax Audit Form 26 which replaces Form 3CD. This is a significant enhancement, both in terms of disclosure and the work effort involved.

What does the existing ICAI Guidance Note say? (Relevant even now)

While we await the ICAI’s Guidance Note specifically on Form 26, the existing Guidance Note on Form 3CD provides useful principles that will likely continue to apply:

• Trading and manufacturing entities should maintain quantitative records of principal items of stores, raw materials, and finished goods.
• Where stock records are not properly maintained – owing to the nature, volume, or variety of transactions – the Tax Auditor must apply the concepts of materiality and practicality while reporting.
• Quantitative details need to be reported only where it is practicable to do so, having regard to the records maintained by the assessee.
• Such details are also required in respect of by-products.

“Principal items” means items constituting more than 10% of aggregate purchases, consumption, or turnover, as the case may be – though this will always depend on the facts of each case.

The Bottom Line for Practitioners:

The scope of work for Tax Auditors has increased manifold under the Income Tax Act 2025 and Rules 2026. Firms will need to:

• Strengthen their teams and internal infrastructure
• Educate clients on maintaining proper quantitative and value-wise records
• Update audit checklists and engagement letters to reflect the enhanced disclosure requirements under Form 26

The time to prepare is now – not in September.
