Tax Audit under Section 44AB: Turnover Limits, 5% Cash Rule & Filing Checklist (AY 2026-27)

By CA Reshma Jadhav, FCA · Satara · Sat Jun 20 2026 05:30:00 GMT+0530 (India Standard Time)

Under Section 44AB of the Income Tax Act, 1961, business entities and professionals crossing statutory turnover thresholds must have their accounts audited by a practising Chartered Accountant. With statutory audit reports due by 30th September 2026 and audited returns by 31st October 2026 for AY 2026-27, understanding your exact audit applicability is essential to prevent penalties under Section 271B.

1. Who is Liable for a Tax Audit u/s 44AB?

The primary purpose of a tax audit is to verify the books of account maintained by a taxpayer, report statutory compliance, compute taxable income accurately, and minimize tax evasion. The statutory thresholds for FY 2025–26 (AY 2026–27) depend on your business classification and transaction mode:

2. Understanding the “₹10 Crore Turnover” 5% Cash Rule

The Finance Act increased the business tax audit limit from ₹1 Crore to ₹10 Crore to promote digital transactions. However, this concession comes with a strict twin test that catches many businesses in Satara, Karad, and Pune off guard:

The Twin Test: Both conditions must be satisfied simultaneously:

1. Aggregate Cash Receipts $\le 5%$ of Total Receipts (including turnover, loans, capital introduction, advances, and asset sales).
2. Aggregate Cash Payments $\le 5%$ of Total Payments (including purchases, expenses, loans repaid, drawings, and capital expenditure).

Real-Life Trap for Local Businesses

If a trader in Satara has a turnover of ₹4 Crore, conducts 98% of sales via RTGS and UPI, but pays ₹35 Lakh in cash for labor, petty expenses, or unorganized purchases (representing 9% of total outflows), the ₹10 Crore exemption is lost immediately. The trader is compulsorily subject to tax audit under the standard ₹1 Crore threshold.

3. Audit Report Forms: Form 3CA vs Form 3CB

A tax audit report is uploaded electronically on the Income Tax e-Filing portal under the digital signature of the Chartered Accountant:

• Form 3CA: Applicable when the taxpayer is already required to have their accounts audited under any other law (for example, Private Limited Companies, Public Limited Companies, or Banks audited under the Companies Act, 2013).
• Form 3CB: Applicable to taxpayers whose accounts are not audited under any other law (such as Sole Proprietorships, Partnership Firms, and individuals).
• Form 3CD: The comprehensive 44-clause detailed statement of particulars that accompanies both Form 3CA and Form 3CB. It reports depreciation, related-party transactions, GST reconciliations, disallowances under Section 40(a), 40A(3) cash expenditure, and Section 43B statutory dues.

4. Key Clauses in Form 3CD Every Business Owner Must Review

1. Clause 21(d) — Disallowance of Cash Payments (Section 40A(3)): Any business payment made in cash exceeding ₹10,000 to a single person in a single day is 100% disallowed and added back to taxable business income.
2. Clause 26 — Statutory Liabilities under Section 43B: Unpaid GST, employee PF/ESIC contributions, or interest to banks not deposited before the return filing due date cannot be deducted as expenditure.
3. Clause 22 — MSME Delayed Payments (Section 43B(h)): Amounts due to registered Micro and Small enterprises remaining unpaid beyond 15 days (or 45 days where written agreement exists) are disallowed as expenses for the year.
4. Clause 44 — Breakup of Total Expenditure in GST: Full reporting of total expenditure into exempt supplies, composition supplies, registered entities, and unregistered entities.

5. Penalty for Not Conducting or Late Filing of Tax Audit (Section 271B)

If a taxpayer required to obtain a tax audit fails to do so or fails to furnish the report by the statutory due date (30 September 2026 for AY 2026–27), the Assessing Officer may levy a penalty under Section 271B of the Income Tax Act, 1961:

$$\text{Penalty} = \min\left(0.5% \text{ of Total Turnover or Gross Receipts}, \text{ ₹1,50,000}\right)$$

In addition to the monetary penalty:

• Losses cannot be carried forward to subsequent years (Section 80).
• Exorbitant additions may be made during faceless scrutiny assessments.
• Interest accrues under Section 234A on any outstanding tax liability.

6. Document Checklist to Prepare for Your Tax Audit

To complete your tax audit without last-minute panic, compile the following records for your Chartered Accountant:

• Complete Tally / ERP financial books closed up to 31 March
• Bank statements for all current, savings, and OD/CC accounts with reconciliation statements
• GST returns (GSTR-1, GSTR-3B, GSTR-9) and annual turnover reconciliation
• Fixed asset purchase bills and depreciation register
• Sundry debtors and sundry creditors balance confirmations
• Year-end physical inventory valuation sheet signed by the proprietor/partner
• TDS quarterly statements (24Q, 26Q) and Form 26AS/AIS
• Details of loans accepted and repaid with PAN of lenders (Clause 31 compliance)
