Clause 8a of Tax Audit Report: Form 3CD Reporting for Concessional Tax Regimes Under Section 115BAA/115BAC
Updated: 4 days ago
Under Section 44AB of the Income-tax Act, 1961, tax audit reporting begins with foundational disclosures regarding the taxpayer's legal identity and tax computation regime. Among these initial requirements, Clause 8a of Form 3CD requires statutory tax auditors to verify and report whether the assessee has exercised the option for concessional taxation regimes under Sections 115BA, 115BAA, 115BAB, 115BAC, 115BAD, or 115BAE.
Update — 28 September 2026: CBDT changed the specified ordinary AY 2026–27 tax-audit report deadline from 30 September to 21 October 2026 and the related audited return deadline from 31 October to 21 November 2026. Section 92E / Form 3CEB cases retain a separate timeline. Official Income Tax Department announcement.
Selecting a concessional tax regime is not merely a tax-rate choice—it permanently alters the assessee's tax profile by extinguishing Minimum Alternate Tax (MAT) obligations, disallowing accelerated capital allowances, and causing accumulated MAT credit balances to lapse.
In this technical audit advisory, PGT & Associates (Chartered Accountants, Ahmedabad) provides a structured breakdown of Clause 8a compliance, statutory form verification protocols (Form 10-IC and Form 10-IEA), forgone incentive reconciliations, and an audit checklist for Assessment Year 2026-27.
1. Statutory Architecture of Clause 8a (Form 3CD)
Clause 8a was inserted into Form 3CD to ensure that tax auditors certify the validity of the taxpayer's concessional regime election prior to the electronic filing of the audit report.
The clause requires the auditor to answer:
"Whether the assessee has opted for taxation under section 115BA / 115BAA / 115BAB / 115BAC / 115BAD / 115BAE?"
(If yes, please indicate the relevant section).

2. Section 115BAA for Corporates: Audit Verification Protocols
For corporate entities audited under Form 3CA-3CD, Section 115BAA remains the primary concessional election:
Verification of Form 10-IC Filing
Under Section 115BAA(5), the option must be exercised by filing Form 10-IC electronically on or before the due date specified under Section 139(1) for furnishing the return of income:
Prior Year Exercise: If Form 10-IC was filed in an earlier assessment year, the option continues to apply to all subsequent years automatically. The auditor must verify the original Form 10-IC acknowledgement receipt and e-filing date.
Current Year Exercise: If opting for the first time in AY 2026-27, the auditor must obtain management confirmation that Form 10-IC has been or will be filed before the 31st October 2026 deadline.
Irrevocability: Once exercised, the option cannot be withdrawn in any subsequent financial year.
3. Disallowed Deductions & Foregone Tax Incentives
When verifying tax computations under Clause 8a, auditors must ensure that all prohibited deductions under Section 115BAA(2) have been added back in full:
Deductions Analysis under Section 115BAA
Strictly Prohibited Allowances:
Additional Depreciation under Section 32(1)(iia)
SEZ Unit Profit Deductions under Section 10AA
Weighted Scientific Research Deductions under Section 35
Chapter VI-A "Heading C" Deductions (Sections 80-IA, 80-IB, 80-IC, 80-IE)
Permitted Deductions Retained:
Normal Block Depreciation under Section 32(1)(ii)
Inter-Corporate Dividend Deductions under Section 80M
Employment Generation Incentives under Section 80JJAA
Routine allowable business expenditures under Sections 30 to 37
The Treatment of Brought-Forward Losses
Under Section 115BAA(2)(b), any brought-forward loss or unabsorbed depreciation from an earlier assessment year that is attributable to additional depreciation or prohibited deductions is not allowed to be set off. Such loss lapses permanently and cannot be carried forward.
4. Minimum Alternate Tax (MAT) Impact: Section 115JB & MAT Credit
Opting for Section 115BAA carries profound consequences for Minimum Alternate Tax (MAT):
Complete MAT Exemption: Under Section 115JB(5A), the provisions of Section 115JB do not apply to a company that has exercised the option under Section 115BAA. The company is completely relieved from MAT computations and Form 29B certifications.
Permanent Lapse of Accumulated MAT Credit: Under Section 115JAA, any accumulated unutilized MAT credit existing on the date of transition cannot be set off against the tax liability under Section 115BAA. The entire MAT credit balance lapses.
Audit Recommendation: Auditors should review the assessee's opening Balance Sheet. If substantial MAT credit is available, management must document a commercial feasibility model demonstrating why adopting 115BAA was commercially beneficial despite forfeiting the MAT asset.
5. Non-Corporate Assessees: Section 115BAC Reporting in Form 3CD
Following amendments to Section 115BAC, the concessional regime is now the default tax regime for Individuals, HUFs, and Association of Persons:
Form 10-IEA Requirements for Business Assessees
If an individual or HUF deriving income from business or profession wishes to compute income under the old tax regime (to claim Chapter VI-A deductions or housing loan interest under Section 24), they must electronically submit Form 10-IEA on or before the due date under Section 139(1) (31st October 2026 for audit cases).
Under Clause 8a, the tax auditor must examine the filed Form 10-IEA to confirm whether the assessee has validly opted out of the default regime.
6. Audit Verification Checklist for AY 2026-27
Before certifying Clause 8a of Form 3CD, tax audit teams should execute the following verification steps:
[ ] Inspect Form 10-IC Acknowledgement: Corroborate the electronic filing acknowledgement number and date of Form 10-IC on the Income Tax e-Filing portal.
[ ] Board Resolution Verification: Verify that the Board of Directors passed a valid resolution approving the exercise of option under Section 115BAA prior to filing Form 10-IC.
[ ] Clause 18 Depreciation Cross-Check: Ensure that depreciation schedules under Clause 18 of Form 3CD do not include any claim for additional depreciation under Section 32(1)(iia).
[ ] Clause 33 Chapter VI-A Audit: Confirm that deductions under Sections 80-IA, 80-IB, 80-IAC, and 80-IE are omitted, while retaining permissible claims under 80JJAA and 80M.
[ ] MAT Credit Balance Verification: Ensure that forfeited MAT credit is written off in the profit and loss account or adjusted against retained earnings in accordance with Ind AS 12.
