ITR-6 Filing for Private Companies in AY 2026-27

ITAI Blogger

August 20, 2026

For a private limited company, filing the correct income tax return is essential for maintaining statutory compliance, claiming eligible deductions and avoiding late fees. Filing of ITR-6 by private companies in AY 2026-27 applies to most companies that do not claim exemption under Section 11 of the Income Tax Act, 1961.

For FY 2025-26, corresponding to AY 2026-27, companies must generally file their return electronically using a Digital Signature Certificate (DSC). A company requiring tax audit will also need to submit the applicable audit report before filing ITR-6.

ITR-6 applicability for Indian private companies

ITR-6 is applicable to a private limited company, public company or other company that is not claiming exemption under Section 11. The return covers income from business, investments, capital gains, house property and other sources.

A private company generally uses ITR-6 if it:

Is incorporated under the Companies Act, 2013 or an earlier company law.
Earns income from business or profession.
Has no income exempt under Section 11.
Has opted for the concessional tax regime under Section 115BAA or Section 115BAB.
Has income from interest, rent, capital gains, dividends or investments.
Has carried-forward business or capital losses.
Has deducted tax at source or paid advance tax.

A company claiming income-tax exemption under Section 11 generally uses ITR-7 instead of ITR-6. This distinction is important because filing the wrong form can lead to a defective return notice.

The Income Tax Department provides the official applicability and filing information through its ITR-6 guidance.

Does a private limited company with no income need to file ITR-6?

Yes. A private limited company may need to file a return even if it has no taxable income or has incurred a loss. Filing is particularly important where the company:

Has incurred a business loss that it wants to carry forward.
Has received income on which tax was deducted.
Has entered into specified financial transactions.
Wants to claim a refund.
Is subject to mandatory company return filing requirements.
Has received a notice requiring a return.

A loss can generally be carried forward only when the company files its return within the prescribed due date, subject to the conditions under the Income Tax Act. Therefore, a loss-making private company should not assume that filing is unnecessary.

ITR-6 due date for private companies AY 2026-27

For FY 2025-26, the normal ITR-6 due date for private companies AY 2026-27 is generally:

Category of company	Due date for AY 2026-27
Private company requiring tax audit	31 October 2026
Company required to furnish Form 3CEB under Section 92E for transfer pricing	30 November 2026
Belated return, subject to statutory limits	31 December 2026

The due date can change if the Central Board of Direct Taxes issues an extension notification. Companies should check the Income Tax Department tax calendar and CBDT notifications before final submission.

The 31 October deadline normally applies because companies are required to get their accounts audited under company law and may also require a tax audit report under Section 44AB. A company involved in international or specified domestic transactions requiring Form 3CEB generally gets the 30 November deadline.

Is the tax audit report due before ITR-6?

Yes. Where tax audit applies, the audit report must generally be furnished electronically before filing the income tax return. The statutory tax audit report is usually due one month before the income tax return due date.

For a company with a 31 October 2026 return deadline, the tax audit report deadline is generally 30 September 2026, unless the Government extends it.

ITR-6 filing for a private limited company under Section 115BAA

Many domestic private companies choose the concessional tax regime under Section 115BAA. This provision allows an eligible domestic company to pay tax at an effective rate of approximately 25.17%, including applicable surcharge and health and education cess, subject to the conditions of the section.

The base income tax rate under Section 115BAA is 22%. A 10% surcharge and 4% health and education cess apply in the normal case.

A company opting for Section 115BAA must file Form 10-IC electronically within the prescribed time. The option is generally exercised on or before the due date for filing the return under Section 139(1).

Important conditions under Section 115BAA

A company opting for Section 115BAA must consider the following:

It must be a domestic company.
It must not claim certain specified deductions and incentives.
It must comply with the conditions relating to depreciation.
The option is generally irrevocable after exercise.
Minimum Alternate Tax provisions do not apply in the usual manner after opting for the regime.
Existing MAT credit may not be available for set-off after exercising the option.

The company should compare the normal tax regime with Section 115BAA before filing Form 10-IC. A company with substantial eligible deductions, brought-forward losses or MAT credit should evaluate the long-term impact instead of choosing the concessional rate automatically.

The official provisions relating to the concessional regime are available in Section 115BAA of the Income Tax Act.

Documents required for ITR-6 filing AY 2026-27

The company does not usually attach financial statements or supporting documents to the ITR. However, it must maintain the records supporting the figures reported in the return.

The key documents required for ITR-6 filing AY 2026-27 include:

Corporate and accounting records

Certificate of incorporation and company Permanent Account Number.

Fixed asset register.
Details of depreciation under the Income Tax Act.

ITR-6 filing with tax audit report for a private company

A private company whose accounts are audited under the Companies Act may need a tax audit under Section 44AB as well. The applicable report is generally:

Form 3CA with Form 3CD when the company is already required to get its accounts audited under another law.
Form 3CB with Form 3CD when the company is not required to get its accounts audited under another law but tax audit applies.

Most private limited companies fall under the first category because company law requires statutory audit of their accounts.

The tax auditor uploads the report using the auditor’s login and DSC. The company must then accept or approve the report from its e-filing account. The audit report details must match the information entered in ITR-6.

Common tax audit and ITR-6 mismatches

Check the following before filing:

Turnover in Form 3CD matches turnover in ITR-6.
Net profit or loss agrees with the audited accounts.
Depreciation under the Income Tax Act is correctly entered.
GST turnover reconciliation explains differences between books and GST returns.
Disallowances under Sections 40(a)(ia), 40A(2), 43B and other provisions are correctly reported.
Related-party transaction details are consistent.
TDS payable and TDS claimed match the company’s records.
Brought-forward losses match earlier income tax returns.
Form 10-IC and the tax regime selected in ITR-6 are consistent.

Practical example of ITR-6 filing

Suppose ABC Private Limited has the following figures for FY 2025-26:

Business turnover: ₹2,40,00,000
Book profit before tax: ₹18,00,000
Depreciation under the Income Tax Act: ₹3,00,000
TDS credit: ₹1,20,000
Advance tax paid: ₹2,00,000
