Tax Audit Under Section 44AB: Applicability, Due Date & Penalties
Quick Answer
Section 44AB of the Income Tax Act, 1961 mandates tax audit for businesses with turnover exceeding Rs.1 crore (or Rs.10 crores if cash transactions do not exceed 5% of total transactions) and professionals with gross receipts exceeding Rs.50 lakhs. The audit report must be filed in Form 3CA-3CD (for entities already audited under another law) or Form 3CB-3CD (for others) by 30th September of the assessment year. Failure attracts a penalty under Section 271B of 0.5% of turnover or Rs.1,50,000 (whichever is lower). At Virtual Auditor, we conduct tax audits across all entity types — proprietorships, partnership firms, LLPs, and companies — ensuring full compliance with ICAI guidance notes and CBDT notifications on Form 3CD reporting.
Definition — Tax Audit (Section 44AB): An audit of the accounts of a person carrying on business or profession, conducted by a chartered accountant as defined in Section 288(2), when the total sales, turnover, or gross receipts of the business exceed the prescribed threshold, or when the gross receipts of the profession exceed the prescribed limit, or when the assessee claims profits lower than the deemed profit under presumptive taxation provisions (Sections 44AD, 44ADA, 44AE).
Definition — Form 3CD: The Statement of Particulars required to be furnished under Section 44AB, containing 44 clauses covering detailed information about the assessee’s business operations, accounting policies, tax-specific adjustments, compliance with TDS/TCS provisions, GST reconciliation, and other prescribed disclosures. Form 3CD is common to both Form 3CA and Form 3CB audit reports.
Applicability of Tax Audit: Who Needs It?
Section 44AB Clauses — Complete Breakdown
Section 44AB contains multiple clauses, each triggering the audit requirement in different circumstances:
| Clause | Applicable To | Threshold / Condition |
|---|---|---|
| 44AB(a) | Business | Total sales/turnover/gross receipts exceed Rs.1 crore (Rs.10 crore if cash receipts and payments each <= 5%) |
| 44AB(b) | Profession | Gross receipts exceed Rs.50 lakhs |
| 44AB(c) | Business (44AD/44ADA/44AE opt-out) | Assessee claims profit lower than deemed rate under Section 44AD, 44ADA, or 44AE and income exceeds basic exemption limit |
| 44AB(d) | Business (44AD opt-out lock-in) | Assessee opted out of Section 44AD and is within the 5-year lock-in period |
| 44AB(e) | Profession (44ADA opt-out) | Assessee claims profit lower than 50% of gross receipts under Section 44ADA and income exceeds basic exemption limit |
The Rs.10 Crore Enhanced Threshold
The Finance Act 2020 introduced a significant relaxation: the turnover threshold for tax audit was enhanced from Rs.1 crore to Rs.10 crores for businesses where:
- Aggregate of all amounts received in cash during the previous year does not exceed 5% of total receipts, AND
- Aggregate of all payments made in cash during the previous year does not exceed 5% of total payments
This enhancement was designed to reduce compliance burden for businesses that conduct substantially all transactions through banking channels. The 5% cash condition must be met for both receipts and payments — failure on either count reverts the threshold to Rs.1 crore.
Expert Insight — CA V. Viswanathan, FCA, ACS, CFE (IBBI/RV/03/2019/12333)
The Rs.10 crore threshold has effectively exempted the majority of digital-first businesses from tax audit. However, the 5% cash condition requires careful monitoring throughout the year — a single large cash receipt or payment near the year-end can breach the threshold and trigger the audit requirement. At Virtual Auditor, we advise businesses with turnover between Rs.1 crore and Rs.10 crores to maintain a real-time cash transaction tracker. We also note that “cash” for this purpose means physical cash — transactions through RTGS, NEFT, UPI, credit/debit cards, and cheques are all considered non-cash. The definition does not extend to demand drafts purchased with cash, which creates a grey area that has been litigated in some cases.
Forms for Tax Audit: 3CA-3CD vs 3CB-3CD
Form 3CA — Audit Report (Statutory Audit Already Conducted)
Form 3CA is used when the assessee is required to get their accounts audited under any other law — most commonly:
- Companies: Audited under Section 143 of the Companies Act, 2013
- Cooperative societies: Audited under the respective State Cooperative Societies Act
- LLPs: Audited under the LLP Act, 2008 (if turnover exceeds Rs.40 lakhs or contribution exceeds Rs.25 lakhs)
Form 3CA contains the auditor’s report confirming that the statutory audit has been conducted, along with observations and qualifications (if any). The tax auditor may be the same chartered accountant who conducted the statutory audit, or a different one.
Form 3CB — Audit Report (No Statutory Audit)
Form 3CB is used when the assessee is not required to get accounts audited under any other law. This applies to:
- Proprietorship businesses
- Partnership firms (not being LLPs with turnover/contribution below the LLP audit thresholds)
- Individuals and HUFs carrying on business or profession
Form 3CB contains the chartered accountant’s independent audit report on the true and fair view of the accounts, along with the balance sheet and profit and loss account.
Form 3CD — Statement of Particulars (Common to Both)
Form 3CD is the substantive document containing 44 clauses of detailed reporting. Key clauses include:
- Clause 8-12: Books of account, nature of business, registration details
- Clause 13: Section 145 — method of accounting (cash/mercantile) and any change during the year
- Clause 14-17: Method of valuation of closing stock, capital gains-related details
- Clause 18: Particulars of depreciation allowable under Section 32
- Clause 21: Amounts debited to profit and loss account that are disallowable under Sections 33AB, 33ABA, 33AC, 35, 35ABB, 35AC, 35AD, 35CCA, 35CCB, 35D, 35DD, 35DDA, 35E
- Clause 26: Amounts inadmissible under Section 40 (interest, salary to partners, etc.)
- Clause 27: Amounts inadmissible under Section 40A (cash payments exceeding Rs.10,000, etc.)
- Clause 30-30C: Deductions under Chapter VI-A
- Clause 34: TDS/TCS compliance — whether tax has been deducted/collected at source as required
- Clause 36A: Compliance with Section 269SS and 269T (cash loan/deposit restrictions)
- Clause 44: GST turnover reconciliation — comparison of turnover reported in GST returns with turnover reported in financial statements
Due Date for Tax Audit Report
Filing Timeline
| Category of Assessee | Tax Audit Report Due Date | ITR Filing Due Date |
|---|---|---|
| Person subject to tax audit under Section 44AB (not requiring TP report) | 30th September of AY | 31st October of AY |
| Person required to furnish transfer pricing report under Section 92E | 31st October of AY | 30th November of AY |
| Person not subject to audit (for reference) | Not applicable | 31st July of AY |
The tax audit report is filed electronically on the income tax e-filing portal by the chartered accountant. The assessee must first add the CA on the portal (using the CA’s membership number and UDIN), and the CA uploads the audit report, which the assessee then accepts or rejects on the portal.
Revised Tax Audit Report
A revised tax audit report can be filed before the due date if errors are discovered in the original report. After the due date, revision is permitted only in cases where the ITR itself is being revised under Section 139(5), or where the AO requires specific corrections during assessment proceedings.
Penalty Under Section 271B
Quantum and Discretion
Section 271B provides that if any person required to get a tax audit fails to do so before the specified date, the Assessing Officer may direct the person to pay a penalty of:
- 0.5% of the total sales, turnover, or gross receipts, or
- Rs.1,50,000
whichever is lower.
Key aspects of Section 271B penalty:
- Discretionary, not mandatory: The section uses the word “may” — the AO has discretion to levy or waive the penalty.
- Reasonable cause defence: Section 273B provides that no penalty under Section 271B shall be imposed if the assessee proves that there was reasonable cause for the failure. Courts have accepted various grounds as reasonable cause — illness of the assessee, natural calamity, non-availability of the CA, disruption in the e-filing portal, etc.
- No double penalty: Penalty under Section 271B is for failure to get accounts audited or failure to furnish the audit report. It does not overlap with the penalty for late filing of ITR under Section 234F.
Expert Insight — CA V. Viswanathan, FCA, ACS, CFE (IBBI/RV/03/2019/12333)
In our experience at Virtual Auditor, Section 271B penalties are increasingly being levied by AOs in cases where the audit report is filed even a few days late. The reasonable cause defence requires proper documentation — a mere verbal claim is insufficient. We advise our clients to maintain contemporaneous records of any genuine reasons for delay (medical certificates, proof of portal downtime, correspondence with the CA showing timely engagement). For businesses approaching the Rs.1 crore threshold in the last quarter, we conduct a mid-year review to determine whether tax audit will be applicable, allowing sufficient time for the CA to complete the audit well before the September deadline.
Tax Audit for Presumptive Taxation Opt-Out
Section 44AB contains specific provisions triggered when an assessee opts out of or declares lower income under presumptive taxation:
- Section 44AB(e) — 44AD opt-out: If a business assessee declares profits below 8% (or 6%) of turnover under Section 44AD, and the total income exceeds the basic exemption limit, tax audit is mandatory regardless of turnover. A business with Rs.40 lakhs turnover but declaring profits below the deemed rate must get a tax audit done.
- Section 44AB(e) — 44ADA opt-out: Similarly, if a professional declares profits below 50% of gross receipts under Section 44ADA, and total income exceeds the basic exemption limit, tax audit is mandatory regardless of whether gross receipts exceed Rs.50 lakhs.
- Five-year lock-in (Section 44AD): An assessee who opted for Section 44AD and then opted out faces mandatory book-keeping and audit requirements for the subsequent five assessment years under Section 44AD(4).
Key Compliance Points for Form 3CD
Clause 44: GST Reconciliation
Clause 44 of Form 3CD, introduced by CBDT Notification No. 33/2018, requires reconciliation of the turnover reported in GST returns (GSTR-1/GSTR-3B) with the turnover reported in the audited financial statements. The clause requires breakdown of differences arising from:
- Unbilled revenue (accrued income not yet invoiced under GST)
- Unadjusted advances (advance receipts on which GST was paid but income not yet recognised)
- Deemed supplies (stock transfers, branch transfers) reported in GST but not in P&L
- Exempted and nil-rated supplies not captured in P&L turnover
Clause 34: TDS/TCS Compliance
Clause 34 requires the tax auditor to report whether the assessee has deducted or collected tax at source as required under the provisions of Chapter XVII-B and XVII-BB. Non-compliance reported in Clause 34 can trigger separate penalty proceedings under Sections 271C and 271CA, and interest demands under Section 201(1A).
Clause 36A: Section 269SS/269T Compliance
Clause 36A reports instances where the assessee has accepted loans, deposits, or specified sums in cash exceeding Rs.20,000, in contravention of Section 269SS, or has repaid such amounts in cash exceeding Rs.20,000, in contravention of Section 269T. Reporting in Clause 36A can trigger penalty under Section 271D (for 269SS violations) and Section 271E (for 269T violations), both equal to 100% of the amount involved.

Frequently Asked Questions
1. Can a CA firm audit its own client’s tax audit if the same firm prepares the accounts?
The Income Tax Act does not explicitly prohibit the same CA or CA firm from preparing the accounts and conducting the tax audit. However, the ICAI ethical standards and the Companies Act, 2013 (for companies) impose restrictions on auditing entities where the auditor has prepared the financial statements. For companies, Section 144 of the Companies Act prohibits the statutory auditor from performing accounting and book-keeping services. For non-company entities (proprietorships, firms), the ICAI recommends maintaining professional independence, though no statutory bar exists.
2. Is tax audit required for a company irrespective of turnover?
No. Companies are not automatically subject to tax audit under Section 44AB merely by virtue of being companies. A company is subject to tax audit only if its turnover exceeds Rs.1 crore (or Rs.10 crore with the 5% cash condition). However, all companies are mandatorily subject to statutory audit under Section 143 of the Companies Act, 2013, irrespective of turnover. The statutory audit and tax audit are separate requirements — a company with turnover below Rs.1 crore requires statutory audit but not tax audit.
3. Can the tax audit report be revised after the due date?
There is no specific provision in the Income Tax Act allowing revision of the tax audit report after the due date. However, the CBDT has clarified that if the ITR is revised under Section 139(5), the tax audit report may also be revised to reflect the changes. In practice, the e-filing portal permits uploading a revised tax audit report (with appropriate justification) before the assessment is completed. The Assessing Officer has the discretion to accept or reject the revised report.
4. What is the UDIN requirement for tax audit?
The ICAI mandates that every tax audit report must carry a Unique Document Identification Number (UDIN) generated from the ICAI UDIN portal. The UDIN must be generated within 60 days from the date of signing the audit report (15 days for initial generation, with a 45-day grace period for regularisation). Tax audit reports uploaded on the e-filing portal without a valid UDIN are flagged for non-compliance, and the ICAI may take disciplinary action against the CA.
5. Does turnover for Section 44AB include GST collected?
The ICAI Guidance Note on Tax Audit (revised 2022) clarifies that “turnover” for Section 44AB purposes should be the exclusive turnover — i.e., net of GST. Since GST collected is not income of the assessee (it is collected on behalf of the government and remitted), it should not be included in the turnover for determining the applicability of Section 44AB. However, if the assessee follows an inclusive method of accounting (where GST is included in the sales figure and shown as an expense), the gross figure may be considered. The safer practice is to compute turnover exclusive of GST.
6. Is tax audit applicable to a loss-making business?
Yes. The applicability of tax audit under Section 44AB(a) depends solely on the turnover threshold, not on profitability. A business with Rs.5 crore turnover and a net loss is still required to get a tax audit if the cash transaction condition is breached (i.e., if cash receipts or payments exceed 5%). The loss does not exempt the assessee from the audit requirement. The only exception is under Section 44AB(e), where the opt-out audit for presumptive taxation is not triggered if the assessee’s total income does not exceed the basic exemption limit.
