Private Company Tax Audit AY 2026-27: Limits & Due Date

ITAI Blogger

August 21, 2026

For FY 2025-26 and AY 2026-27, a private limited company may need two different audits: a statutory audit under the Companies Act, 2013 and a tax audit under Section 44AB of the Income-tax Act, 1961. The statutory audit generally applies to every company, while the income tax audit depends mainly on turnover, cash receipts and cash payments.

For most private companies carrying on business, the key rule is simple:

Tax audit is generally required when business turnover exceeds ₹1 crore.
The threshold increases to ₹10 crore when both cash receipt and cash payment conditions are satisfied.
The company must file Form 3CA along with Form 3CD because its accounts are audited under company law.
The expected tax audit report due date for AY 2026-27 is 30 September 2026, and the income tax return due date for an audited company is generally 31 October 2026, subject to any CBDT extension.

When is a Private Company Eligible for Audit in AY 2026-27 for ITR-6?

A private company filing ITR-6 becomes liable for an income tax audit under Section 44AB mainly when its business turnover crosses the applicable threshold.

Standard ₹1 crore tax audit limit

A private company carrying on business must obtain a tax audit if its sales, turnover or gross receipts exceed ₹1 crore during FY 2025-26.

The threshold is based on business turnover and not on the company’s profit. Therefore, a company reporting a loss may still require a tax audit if its turnover crosses the limit.

For example:

Business turnover during FY 2025-26	Tax audit under Section 44AB
₹85 lakh	Generally not required only because of turnover
₹1 crore exactly	Generally not required under the “exceeds” test
₹1,20,00,000	Required, subject to other provisions
₹12 crore	Required

This is the main answer to the question, “When is a private company liable for tax audit under Section 44AB for AY 2026-27?”

The relevant provisions are available in the Income-tax Act, 1961.

₹10 Crore Tax Audit Limit for Private Companies: Cash Receipts and Payments

The tax audit threshold for a business can increase from ₹1 crore to ₹10 crore if the company satisfies both cash transaction conditions under Section 44AB.

The ₹10 crore limit applies when:

Aggregate cash receipts do not exceed 5% of total receipts, and
Aggregate cash payments do not exceed 5% of total payments.

Both conditions must be satisfied. Meeting only one condition is not enough.

Example 1: Company qualifies for the ₹10 crore threshold

A private company reports the following for FY 2025-26:

Total business receipts: ₹8 crore
Cash receipts: ₹12 lakh
Total payments: ₹6 crore
Cash payments: ₹18 lakh

Cash receipt percentage:

₹12 lakh ÷ ₹8 crore × 100 = 1.5%

Cash payment percentage:

₹18 lakh ÷ ₹6 crore × 100 = 3%

Since both percentages are within 5%, the company may use the enhanced ₹10 crore tax audit limit. If its turnover is ₹8 crore, it would generally not require a tax audit solely under Section 44AB(a).

Example 2: Company does not qualify for the ₹10 crore threshold

Assume another company has:

Total receipts: ₹6 crore
Cash receipts: ₹40 lakh

Cash receipts are 6.67% of total receipts. Since the cash receipt condition exceeds 5%, the company cannot use the ₹10 crore threshold.

If its turnover exceeds ₹1 crore, it will generally require a tax audit.

Important points about the 5% test

The company should calculate the percentage using the complete financial year’s transactions. It should also maintain clear records of:

Cash sales and cash collections
Cash advances received
Cash purchases
Cash expenses
Cash payments to suppliers and employees
Payments made through banking channels
Receipts through account-payee instruments and electronic modes

The company should not assume that a low cash balance automatically satisfies the test. The law examines aggregate receipts and aggregate payments, not only the closing cash balance.

Private Company Tax Audit Limit AY 2026-27: Which Threshold Applies?

The following table summarises the applicable turnover limits for a private limited company carrying on business:

Situation	Applicable turnover threshold
Cash receipts or cash payments exceed the permitted 5% condition	₹1 crore
Cash receipts and cash payments are both within 5%	₹10 crore
Turnover exceeds the applicable threshold	Tax audit generally required
Turnover is below the applicable threshold	Tax audit generally not required under the normal turnover test

The threshold applies to business turnover or gross receipts. A company should not automatically combine unrelated receipts without analysing whether they form part of business turnover.

For example, a company may need to separately evaluate:

Sale of goods
Service income
Job-work receipts
Export turnover
Commission income
Reimbursement receipts
Interest and other non-operating income

The correct classification depends on the nature of the company’s activities and accounting records.

ITR-6 Tax Audit Applicability for Private Limited Company AY 2026-27

A private limited company generally files its income tax return using ITR-6, unless it is required to file ITR-7 because of income covered by specific charitable or religious trust provisions.

The ITR-6 tax audit process usually involves the following:

The company prepares its financial statements for FY 2025-26.
The statutory auditor audits the accounts under the Companies Act.
A chartered accountant prepares and uploads the tax audit report.
The company approves the report on the income tax e-filing portal.
The company files ITR-6 using the audit details and financial information.
The company verifies the return electronically or through the permitted verification process.

The Income Tax Department’s e-filing portal provides the applicable forms, filing utilities and tax audit reporting functionality.

Does every private company filing ITR-6 require a tax audit?

No. Filing ITR-6 does not automatically mean that a company requires a tax audit under Section 44AB.

However, every private company normally has to comply with its statutory financial statement audit requirements under company law. The company must then determine separately whether Section 44AB applies.

This distinction is important because many taxpayers incorrectly treat the following as the same:

Statutory audit under the Companies Act
Tax audit under the Income-tax Act
Filing of ITR-6

They are separate compliance requirements.

Private Company Statutory Audit Versus Income Tax Audit AY 2026-27

Statutory audit under the Companies Act

A company’s statutory auditor examines whether its financial statements present a true and fair view and comply with applicable accounting and company law requirements.

The statutory audit generally covers:

Balance Sheet
Statement of Profit and Loss
Cash Flow Statement, where applicable
Statement of Changes in Equity, where applicable
Notes to accounts
Books and supporting records
Compliance with applicable provisions of the Companies Act

The Ministry of Corporate Affairs administers the Companies Act, 2013.

Tax audit under Section 44AB

A tax audit focuses on information relevant to income tax compliance. It reports prescribed details such as:

Turnover and gross receipts
Profit or loss
Depreciation
Disallowable expenses
Related-party payments
Tax deducted at source
Loans and deposits covered by Section 269SS
Repayments covered by Section 269T
Cash transactions
GST and other indirect tax details, where relevant
Computation of taxable income adjustments

The tax auditor reports these details in Form 3CD.

A private company may therefore have a statutory audit even when it does not have an income tax audit obligation under Section 44AB.

Form 3CA and Form 3CD for Private Limited Company

A private limited company whose accounts are already audited under another law must generally submit:

Form 3CA: Audit report under Section 44AB where accounts are audited under another law
Form 3CD: Statement of particulars required under Section 44AB

Since a company’s accounts are ordinarily audited under the Companies Act, Form 3CA and Form 3CD are generally relevant for an audited private limited company filing ITR-6.

Form 3CA versus Form 3CB

The distinction is as follows:

Form	When used
Form 3CA	Accounts are audited under another law, such as the Companies Act
Form 3CB	Accounts are not audited under any other law
Form 3CD	Detailed statement of tax audit particulars accompanying Form 3CA or 3CB

The tax auditor uploads the applicable report electronically. The company must review and accept or approve it through its e-filing account.

The company should ensure that the figures in Form 3CD agree with:

Audited financial statements
General ledger
Trial balance
GST returns
TDS returns
Bank statements
Fixed asset register
Income tax computation

Differences between these records can result in notices, clarification requests or additional compliance.

Private Company Tax Audit Due Date for AY 2026-27

For FY 2025-26 and AY 2026-27, the expected due dates are:

Compliance	Expected due date
Tax audit report in Form 3CA and Form 3CD	30 September 2026
ITR-6 for an audited company	31 October 2026
ITR-6 where transfer pricing report applies	30 November 2026

The tax audit report is generally due one month before the income tax return due date.

A company covered by transfer pricing provisions under Section 92E will generally have an earlier audit-related compliance deadline and a later return filing deadline. Such companies should separately track:

Form 3CEB
International transactions
Specified domestic transactions, where applicable
Accountant’s report under transfer pricing provisions
ITR-6 filing date

The official income tax due-date guidance should be checked for any notification extending these dates.

Tax Audit Exemption for Private Limited Company Under Section 44AB

A private limited company may not need a tax audit under the normal Section 44AB turnover test when:

Its business turnover does not exceed ₹1 crore, or
Its turnover does not exceed ₹10 crore and both cash receipt and cash payment conditions are satisfied.

However, this does not exempt the company from its statutory audit under the Companies Act.

The company may also have other reporting obligations even when a tax audit is not required. These may include:

Annual financial statements
Board’s report
Annual return
Tax return in ITR-6
TDS returns
GST returns
Transfer pricing documentation, where applicable
Maintenance of books of account
Tax deduction and collection compliance

A company should also review whether any special provision triggers audit or reporting requirements independently of the ordinary turnover threshold.

Frequently Asked Questions

Is tax audit mandatory for a private company with turnover below ₹1 crore?

Usually, no, if the company is not covered by another specific audit condition under Section 44AB. However, the company’s statutory audit under the Companies Act generally continues to apply.

Is tax audit required if turnover is ₹5 crore but all transactions are digital?

Not automatically. The company can generally use the ₹10 crore threshold only when both aggregate cash receipts and aggregate cash payments do not exceed 5% of the respective totals.

Does a company with a loss need a tax audit?

Yes, potentially. Tax audit applicability is generally linked to turnover and specified conditions, not merely to whether the company earned a profit.

Can a private company use Section 44AD to avoid tax audit?

A private limited company generally cannot claim the presumptive taxation scheme under Section 44AD because that provision is not designed for companies. It should not use Section 44AD as a tax audit exemption without checking eligibility.

Which form does a private company file with ITR-6?

A private company requiring a tax audit will generally use Form 3CA and Form 3CD because its accounts are audited under the Companies Act. Form 3CB is generally relevant where accounts are not audited under another law.

What is the tax audit due date for a private company for AY 2026-27?

The expected tax audit report due date is 30 September 2026. The expected ITR-6 due date for an audited company is 31 October 2026, unless the tax authorities announce a change.

Summary

For AY 2026-27, a private company carrying on business generally requires an income tax audit when its turnover exceeds ₹1 crore. The threshold increases to ₹10 crore only when both cash receipts and cash payments remain within 5% of total receipts and payments. The company normally files Form 3CA, Form 3CD and ITR-6, while its statutory audit remains a separate Companies Act requirement. Private companies should calculate the ₹1 crore or ₹10 crore private company tax audit limit for FY 2025-26, complete Form 3CA and Form 3CD by the applicable date, and file audited ITR-6 for AY 2026-27 within the prescribed deadline.
