Statutory Due Dates for AY 2026-27 (FY 2025-26)

Under Section 44AB of the Income-tax Act, 1961, an eligible assessee must get their accounts audited by an independent Chartered Accountant and electronically furnish the audit report on or before the specified date. The specified date is defined as one month prior to the due date for furnishing the return of income under Section 139(1).

• Tax Audit Report Due Date (General Assessees): 30th September 2026

• Income Tax Return (ITR) Due Date for Audited Assessees: 31st October 2026

• Tax Audit Report Due Date (Transfer Pricing / Form 3CEB Cases): 31st October 2026

• ITR Due Date for International / Specified Domestic Transaction Cases: 30th November 2026

Filing the Tax Audit Report on the Income Tax e-Filing Portal (https://www.incometax.gov.in) requires both the certifying Chartered Accountant and the taxpayer's authorized signatory to approve and digitally verify the report using Digital Signature Certificates (DSC).

Section 44AB Applicability Thresholds for AY 2026-27

Determining whether a business or professional is required to undergo a tax audit depends on gross turnover, receipts, and cash transaction ratios:

1. Business Assessees (Section 44AB(a))

• Standard Threshold: Total sales, turnover, or gross receipts exceeding Rs. 1 Crore in FY 2025-26.

• Enhanced Digital Threshold (Rs. 10 Crores): If aggregate cash receipts (including loans, capital, and sales) and aggregate cash payments (including expenses, capital expenditure, and loan repayments) do not exceed 5% of total receipts and payments respectively, the audit threshold is raised to Rs. 10 Crores.

2. Professional Assessees (Section 44AB(b))

• Standard Threshold: Gross receipts in profession exceeding Rs. 50 Lakhs.

• Presumptive Taxation Relief (Section 44ADA): The threshold is enhanced to Rs. 75 Lakhs where aggregate cash receipts do not exceed 5% of gross receipts.

3. Presumptive Taxation Opt-Out (Section 44AD(4) & 44AB(e))

• Under Section 44AD, eligible resident individuals, HUFs, and partnership firms with turnover up to Rs. 2 Crores (or Rs. 3 Crores where cash receipts are within 5%) can declare 8% or 6% profits.

• The 5-Year Lock-In Rule: If an assessee declares profits on a presumptive basis under Section 44AD in one year and subsequently declares profits lower than the presumptive percentage in any of the next 5 assessment years, they are locked out of Section 44AD for the subsequent 5 consecutive assessment years and are statutorily required to maintain books under Section 44AA and obtain a tax audit under Section 44AB(e).

Choosing the Right Audit Form: Form 3CA vs. Form 3CB

The tax audit report consists of two distinct components: the audit certificate and the statement of particulars (Form 3CD).

• Form 3CA: Applicable to assessees whose accounts are already required to be audited under any other law (such as companies governed by the Companies Act, 2013, or societies governed by Cooperative Societies Acts). The auditor's role is to report whether the financial statements match the statutory audit and verify Form 3CD particulars.

• Form 3CB: Applicable to assessees not subjected to mandatory audit under any other law (such as sole proprietorships, partnerships, or LLPs not crossing statutory company audit limits). The Chartered Accountant provides a full independent true-and-fair view audit opinion on the Balance Sheet and Profit and Loss Account alongside certifying Form 3CD.

• Form 3CD: The comprehensive statement of particulars containing 44 statutory clauses detailing accounting policies, inventory valuation, statutory liabilities, and transaction reporting.

Key Form 3CD Clauses Requiring Rigorous Audit Review for AY 2026-27

1. Clause 8 - Applicable Sub-clause of Section 44AB

Auditors must explicitly record whether the audit is conducted under Section 44AB(a), 44AB(b), 44AB(c), 44AB(d), or 44AB(e), especially where the assessee claims the benefit of the Rs. 10 Crore digital turnover limit.

2. Clause 14 - Inventory Valuation & Section 145A

Inventory valuation must adhere to Section 145A and the ICAI Accounting Standards (AS 2 / Ind AS 2). All taxes, duties, cesses, or fees actually paid or incurred to bring goods to their present location and condition must be appropriately integrated into valuation, with reconciliation of any deviation from books.

3. Clause 21(a) - Capital, Personal & Section 40(a) Disallowances

Scrutiny of expenditures charged to the Profit & Loss Account to identify items of personal or capital nature, and non-compliance with TDS provisions under Section 40(a)(ia) (30% disallowance for non-deduction/non-payment of resident TDS) and Section 40(a)(i) (100% disallowance for non-resident payments).

4. Clause 26 & Section 43B(h) - MSME Timely Payments

Section 43B(h) mandates that any sum payable to a Micro or Small Enterprise registered under the MSMED Act, 2006 beyond the time limit specified in Section 15 of that Act (maximum 15 days, or up to 45 days pursuant to written agreement) is allowed as a tax deduction only in the year of actual payment. Unpaid amounts at fiscal year-end are added back to taxable income, making vendor classification and payment tracking critical.

5. Clause 31 - Acceptance & Repayment of Loans/Deposits (Section 269SS & 269T)

Auditors must audit transactions involving acceptance or repayment of loans, deposits, or specified advances in cash exceeding Rs. 20,000, ensuring compliance with Section 269SS and Section 269T.

6. Clause 34 - Comprehensive TDS/TCS Reconciliation

Clause 34 requires an extensive reconciliation across three critical sub-clauses:

• Clause 34(a): Verification whether the assessee was liable to deduct or collect tax, total amounts subjected to deduction, amounts deducted at specified rates, and amounts deducted at lower/zero rates.

• Clause 34(b): Verification whether quarterly statements (Form 24Q, Form 26Q, Form 27Q, Form 27EQ) were furnished within statutory timelines and contained complete information.

• Clause 34(c): Verification whether interest under Section 201(1A) or Section 206C(7) was payable, calculated accurately, and duly remitted to the government treasury.

Consequences of Non-Compliance: Section 271B Penalty

Failure to get accounts audited or submit the tax audit report by the 30th September 2026 due date attracts statutory penal proceedings under Section 271B of the Income-tax Act, 1961:

• Penalty Amount: A sum equal to 0.5% of total sales, turnover, or gross receipts, or Rs. 1,50,000, whichever is lower.

• Reasonable Cause Protection: Under Section 273B, penalties under Section 271B may be waived if the taxpayer successfully proves genuine reasonable causes, such as sudden illness of the auditor/assessee, natural calamities, or unforeseen systemic portal failure.
