Tax Audit for Private Limited Companies : Rules, ICAI Guidelines, and Extended Due Date
Introduction
A Tax Audit ensures that the financial statements of a Private Limited Company meet the requirements of the Income Tax Act. It becomes mandatory under Section 44AB once turnover or receipts exceed specified limits. With ICAI’s restrictions on the number of audits per Chartered Accountant and CBDT’s extension of the deadline for AY 2025-26, it is important for companies to stay updated.
Tax Audit Process for Private Limited Companies
-
Appoint a Chartered Accountant with available capacity under ICAI limits.
-
The CA prepares Form 3CA/3CB and Form 3CD based on company records.
-
The report is uploaded on the Income Tax Portal using DSC.
-
The company’s authorized signatory accepts the report.
-
The audit report is linked to the company’s Income Tax Return (ITR).
Applicability of Tax Audit
| Category | Applicability |
| Business (General) | Turnover above ₹1 crore |
| Business where cash receipts do not exceed 5% of aggregate receipts and cash payments do not exceed 5% of aggregate payments | Tax-audit threshold increases from ₹1 crore to ₹10 crore; audit is required when turnover exceeds the applicable threshold. |
| Professional Services | Gross receipts above ₹50 lakhs |

Extended Due Date for AY 2025-26
For AY 2025-26, the tax-audit report due date was first extended from 30 September 2025 to 31 October 2025 and was subsequently extended to 10 November 2025. Use 10 November 2025 as the final applicable extended date for the affected audit cases.
This extra month gives companies more time, but it is still advisable to complete the audit early to avoid technical glitches or last-minute errors.
ICAI Limit on Tax Audits
The Institute of Chartered Accountants of India (ICAI) has capped the number of tax audits a Chartered Accountant can undertake at 60 per year, effective from 1st April 2026.
-
This applies to both individual CAs and partners in firms.
-
Audits conducted under presumptive taxation schemes are not counted in the limit.
-
Revised reports do not reduce the audit count.

Penalty for Non-Compliance
If a company fails to file the Tax Audit Report on time:
-
A penalty of 0.5% of turnover or ₹1,50,000 (whichever is lower) may be levied under Section 271B.
-
Relief is possible under Section 273B for genuine reasons such as natural disasters, illness, or technical issues.
