What is ITR-6 and When is it Applicable?
\n\nITR-6 is the income tax return form specifically designed for companies registered under the Companies Act, 2013 or the Companies Act, 1956. Unlike individual taxpayers who file ITR-1, ITR-2, or ITR-3, every company conducting business in India—regardless of profitability—must file ITR-6 to report its financial performance and tax liability to the Income Tax Department.
\n\nThe form captures comprehensive financial data including revenue from operations, capital gains, income from other sources, deductions claimed, taxes paid through TDS and advance tax, and carried forward losses. For Assessment Year 2026-27 (corresponding to Financial Year 2025-26), the Income Tax Department has released both the online filing option and the downloadable Excel utility to facilitate corporate tax compliance.
\n\nWho is NOT Required to File ITR-6?
\n\nCompanies claiming exemption under Section 11 of the Income Tax Act—which covers charitable and religious trusts or institutions—are exempt from filing ITR-6. These entities must file ITR-7 instead. Additionally, Limited Liability Partnerships (LLPs) are required to file ITR-5, not ITR-6, as they are treated differently under tax law despite having some corporate characteristics.
\n\nWho Should File ITR-6 for Assessment Year 2026-27?
\n\nThe following categories of companies are mandatorily required to file ITR-6:
\n\n- \n
- Private Limited Companies: All private companies incorporated under the Companies Act, whether they have earned profits or incurred losses during FY 2025-26 \n
- Public Limited Companies: Listed and unlisted public companies operating in India must file ITR-6 irrespective of turnover or profit margins \n
- Foreign Companies: Foreign companies having a permanent establishment (PE) or business operations in India are liable to file ITR-6 for income attributable to Indian operations \n
- Companies Under Liquidation: Even companies undergoing winding-up or liquidation proceedings must file returns until final dissolution \n
- Dormant Companies: Companies with no significant accounting transactions but still registered under the Companies Act must file a NIL return using ITR-6 \n
- Section 8 Companies: Not-for-profit companies registered under Section 8 of the Companies Act that do not claim Section 11 exemption must use ITR-6 \n
Understanding your filing obligation is critical. Use the Income Tax Calculator to estimate your company's tax liability before starting the ITR-6 filing process.

\n\n| Company Type | \nDue Date for AY 2026-27 | \nApplicable Section | \nPenalty for Delay | \n

Consequences of Missing the Deadline
\n\nFailing to file ITR-6 by the due date triggers multiple penalties:
\n\n- \n
- Late Filing Fee (Section 234F): ₹10,000 flat penalty for companies, regardless of tax liability \n
- Interest on Unpaid Tax (Section 234A): 1% per month or part of month on the tax amount remaining unpaid from the due date until the date of filing \n
- Loss of Carry Forward: Losses other than business loss and depreciation cannot be carried forward if return is filed after the due date \n
- Prosecution Risk (Section 276CC): Willful non-filing can lead to prosecution with rigorous imprisonment ranging from 6 months to 7 years depending on tax evasion amount \n
Common Mistakes to Avoid While Filing ITR-6
\n\nBased on patterns observed in assessment proceedings and notices issued by the Income Tax Department, here are critical errors to avoid:
\n\n1. Mismatch with Form 26AS
\n\nOne of the most common reasons for scrutiny notices is discrepancy between TDS claimed in ITR-6 and TDS reflected in Form 26AS. Always cross-verify every TDS entry before filing. The automated Form 26AS / TDS Fetch Tool helps identify mismatches instantly.
\n\n2. Incorrect Depreciation Calculation
\n\nCompanies often confuse depreciation rates under Companies Act (for financial reporting) with rates prescribed under Income Tax Act (for tax computation). ITR-6 requires depreciation as per Income Tax Act rates specified in the relevant schedule. Maintain a separate depreciation register for tax purposes.
\n\n3. Missing Foreign Asset Disclosure
\n\nSchedule FA (Foreign Assets) is mandatory for companies holding foreign assets, foreign bank accounts, or having signing authority in overseas accounts. Non-disclosure attracts penalty of ₹10 lakh under Section 271FA. Even if your company has divested foreign holdings during the year, disclosure is required.
\n\n4. Overlooking Advance Tax Requirements
\n\nCompanies with tax liability must pay advance tax in four installments during the financial year. Interest under Section 234B and 234C applies if advance tax is short-paid or paid late. Calculate your quarterly tax obligation accurately using the Income Tax Calculator to avoid interest charges that can add up to 3% of your tax liability.
\n\n5. Invalid Digital Signature
\n\nITR-6 cannot be e-verified using Aadhaar OTP; it mandates Digital Signature Certificate (DSC). Ensure your DSC is valid, not expired, and registered with the e-filing portal under your company's PAN. Invalid or expired DSC leads to return rejection.
\n\nSpecial Considerations for AY 2026-27 ITR-6 Filing
\n\nTax Regime for Companies
\n\p>Unlike individual taxpayers who can choose between old and new tax regimes, companies have specific tax rate structures. Domestic companies can opt for the concessional 22% tax rate under Section 115BAA (plus surcharge and cess) provided they don't claim certain deductions and incentives. Companies must carefully evaluate which regime minimizes their tax liability for FY 2025-26.\n\nDividend Distribution Tax (DDT) Abolished
\n\nSince the Finance Act 2020, DDT has been abolished and dividends are now taxable in the hands of shareholders under Section 194 (TDS on dividends). Companies must ensure they've correctly deducted TDS on dividend payments made during FY 2025-26 and reported these in their quarterly TDS returns.
\n\nMinimum Alternate Tax (MAT) Provisions
\n\nCompanies showing book profits but claiming exemptions resulting in NIL or low taxable income may be subject to Minimum Alternate Tax under Section 115JB at 15% (plus surcharge and cess) on book profits. MAT credit can be carried forward for 15 years and adjusted against future regular tax liability. Ensure accurate MAT computation and credit claim in ITR-6.
\n\nFrequently Asked Questions
\n\nWhich companies are required to file ITR-6 for AY 2026-27?
\n\nAll companies incorporated in India or operating through Indian subsidiaries must file ITR-6, except those claiming exemption under Section 11 of the Income Tax Act (charitable and religious trusts). This includes private limited companies, public limited companies, foreign companies with permanent establishments in India, and companies under liquidation. Limited Liability Partnerships (LLPs) file ITR-5, not ITR-6.
\n\nWhat is the last date to file ITR-6 for Assessment Year 2026-27?
\n\nFor companies not requiring a tax audit, the ITR-6 deadline is October 31, 2026.

\n\nLate filing of ITR-6 attracts a penalty under Section 234F: ₹10,000 if filed after the due date. Additionally, interest under Section 234A is charged at 1% per month on unpaid tax from the due date until payment. Companies filing after December 31, 2026 cannot carry forward certain losses except business loss and depreciation. Repeated non-filing can lead to prosecution under Section 276CC with imprisonment up to 7 years.
\n\nWhat documents are mandatory for ITR-6 filing in 2026?
