What is the due date for ITR-6 filing for AY 2026-27?

For AY 2026-27, ITR-6 is due 31 October 2026 for companies requiring tax audit under Section 44AB. Companies with international or specified domestic transactions falling under Section 92E transfer pricing have until 30 November 2026. The corresponding tax audit report (Form 3CA-3CD or 3CB-3CD) must be filed by 30 September 2026, one month before the ITR due date. Belated ITR under Section 139(4) is allowed till 31 December 2026 with a Section 234F fee.

Who can file ITR-6 for AY 2026-27?

ITR-6 is filed by every company under Section 2(17) of the Income Tax Act 1961 - Pvt Ltd, Public Ltd, OPC, foreign companies, and producer companies - except those claiming Section 11 exemption. Charitable trusts, Section 8 companies registered under Section 12A, and religious institutions file ITR-7 instead. Filing is mandatory regardless of profit, loss, or zero revenue. ITR-6 must be e-filed with a valid Director, MD, or CFO DSC.

What is the difference between Section 115BAA and Section 115BAB?

Section 115BAA offers domestic companies a concessional 22 percent basic tax rate with effective 25.168 percent (including 10 percent surcharge and 4 percent cess) and exempts them from MAT under Section 115JB. Section 115BAB applies only to new domestic manufacturing companies set up after 1 October 2019 commencing manufacture before 31 March 2024, with 15 percent basic rate and 17.16 percent effective rate. Both regimes block most Chapter VI-A deductions including Section 80-IAC.

How much does company ITR-6 filing cost with Patron?

Patron Accounting company ITR filing starts at Rs 2,999 for basic Pvt Ltd or OPC with turnover under Rs 5 crore and no transfer pricing. Mid-size Pvt Ltd with Section 115BAA opt-in starts at Rs 9,999. DPIIT startup with Section 80-IAC claim starts at Rs 14,999. Transfer pricing cases with Form 3CEB start at Rs 35,000. NIL ITR for dormant companies is Rs 1,999. Tax audit fees are quoted separately.

How does Section 80-IAC startup tax holiday work?

Section 80-IAC allows DPIIT-recognised Pvt Ltd companies and LLPs to claim 100 percent deduction of profits from eligible business for 3 consecutive AYs out of the first 10 years from incorporation. Eligibility requires Pvt Ltd or LLP structure (not partnership firm), incorporation between 1 April 2016 and 1 April 2030, turnover under Rs 100 crore, and a separate IMB (Inter-Ministerial Board) certificate beyond DPIIT recognition. Only about 3,700 of 207,135 DPIIT-recognised startups hold IMB approval - a 1.8 percent conversion rate.

Can I opt for Section 115BAA and still claim Section 80-IAC?

No. Section 115BAA explicitly disallows deductions under Sections 80-IA, 80-IAB, 80-IAC, and most Chapter VI-A provisions except Sections 80JJAA and 80M. The election under Section 115BAA is irrevocable once made by filing Form 10-IC. For DPIIT-recognised startups with IMB certification, claiming 80-IAC under standard tax rates is usually more beneficial than 115BAA - run a 10-year projection before electing.

Is MAT applicable to all companies for AY 2026-27?

Minimum Alternate Tax under Section 115JB applies at 15 percent of book profit when regular tax is lower than 15 percent of book profit. MAT does not apply to companies opting for Section 115BAA or Section 115BAB. The excess of MAT over regular tax is available as MAT credit under Section 115JAA for set-off in subsequent years for 15 years. Foreign companies with India PE are also liable for MAT on income attributable to the PE.

Is DSC mandatory for company ITR-6 filing?

Yes. ITR-6 can only be e-filed with a valid Class 2 or Class 3 Digital Signature Certificate of the Managing Director, Director, or CFO. Alternative verification methods such as Aadhaar OTP, net banking EVC, or bank account EVC are not permitted for companies. An expired DSC at the time of filing makes the return invalid. The DSC must match the PAN of the authorised signatory registered with the Income Tax e-filing portal.

Our DPIIT SaaS startup was about to opt into 115BAA on auditor advice. Patron ran a 10-year projection showing we'd lose Rs 82 lakh in 80-IAC across the next 3 profitable years. Filed with 80-IAC instead.

Company ITR-6 Filing for AY 2026-27

📌 TL;DR - ITR Filing for Companies Services at a Glance

ITR Filing for Companies in India uses Form ITR-6 under Section 139 of the Income Tax Act, 1961. For AY 2026-27, audit cases are due 31 October 2026 and transfer pricing cases 30 November 2026. Tax rates range from 15 percent under Section 115BAB for new manufacturing companies to 22 percent under Section 115BAA and 30 percent under standard rates, with MAT at 15 percent under Section 115JB. The new Income Tax Act 2025 applies from Tax Year 2026-27 returns due in 2027 - existing Sections 115BAA, 115BAB, 80-IAC, 115JB carry forward into the new Act.

ITR Filing for Companies covers every domestic and foreign company incorporated under the Companies Act, 2013 or earlier Companies Act, 1956. Form ITR-6 is mandatory for all companies except those claiming exemption under Section 11 of the Income Tax Act 1961 (charitable trusts and Section 8 companies file ITR-7). Tax regime selection between standard rates and the concessional Section 115BAA (22 percent) or Section 115BAB (15 percent for new manufacturing) regimes determines effective tax outflow, MAT applicability under Section 115JB, and eligibility for deductions including the Section 80-IAC startup tax holiday.

Patron Accounting has filed 3,000+ company ITRs across Pvt Ltd, OPC, public limited, DPIIT-recognised startups, and foreign company structures with India Permanent Establishment. The firm coordinates statutory audit, tax audit under Section 44AB, MAT computation, transfer pricing under Section 92E with Form 3CEB and Schedule TPSA, and Section 80-IAC year-selection strategy under a single corporate tax engagement. With offices in Pune, Mumbai, Delhi, and Gurugram and 15+ years of corporate compliance practice, every ITR-6 filing comes with 10-year regime projection (Section 115BAA vs Standard + 80-IAC + MAT), MAT credit tracking under Section 115JAA across the 15-year window, and 12 months of post-filing Section 143(1), 143(2), 142(1) and 148 notice support at no extra cost.

What Is Company ITR-6 Filing

Company ITR Filing is the annual return filed by a company under Section 139(1) of the Income Tax Act, 1961, declaring total income, tax liability, MAT (Minimum Alternate Tax), and deductions for a financial year. Form ITR-6 is used for all companies except those claiming Section 11 exemption (which file ITR-7 instead).

Filing is mandatory for every company defined under Section 2(17) - Pvt Ltd, Public Ltd, OPC, foreign company with Indian source income, producer companies - regardless of whether the company has profit, loss, or zero revenue. There is no exemption threshold for companies under Section 139(1). The return must be e-filed with a valid Digital Signature Certificate (DSC) of a Director, Managing Director, or CFO. Aadhaar OTP, net banking EVC, and bank account EVC are not permitted for company filings.

Three corporate tax regimes are available for AY 2026-27. The Standard regime applies a 25 percent rate (if previous year turnover was up to Rs 400 crore) or 30 percent otherwise, with full MAT applicability and all Chapter VI-A deductions available. Section 115BAA offers a concessional 22 percent basic rate (effective 25.168 percent with surcharge and cess) and exempts the company from MAT, but blocks most Chapter VI-A deductions including Section 80-IAC. Section 115BAB offers a 15 percent rate (effective 17.16 percent) but is limited to new domestic manufacturing companies set up after 1 October 2019 and commencing manufacture before 31 March 2024.

Key Terms for ITR Filing for Companies:

ITR-6: Income Tax Return form for companies (not claiming Section 11 exemption). Mandatory e-filing with DSC; cannot be filed with Aadhaar OTP or net banking EVC.

Section 115BAA: Concessional 22 percent tax rate for domestic companies; effective rate 25.168 percent including 10 percent surcharge and 4 percent cess. Filed via Form 10-IC before ITR due date. Election is irrevocable; blocks most Chapter VI-A deductions; exempt from MAT.

Section 115BAB: 15 percent tax rate for new domestic manufacturing companies set up after 1 October 2019 and commencing manufacture before 31 March 2024. Filed via Form 10-ID. Effective rate 17.16 percent.

MAT (Minimum Alternate Tax): 15 percent of book profit under Section 115JB Explanation 1. Does not apply to companies opting for Section 115BAA or Section 115BAB. MAT credit under Section 115JAA carries forward for 15 years for set-off against future normal tax.

Section 80-IAC: 100 percent deduction of profits for 3 consecutive AYs out of the first 10 years from incorporation for eligible DPIIT-recognised startups with IMB certification.

Form 3CEB: Transfer pricing accountant report for international transactions and specified domestic transactions under Section 92E. Due 31 October 2026 for AY 2026-27.

Form 10-IC and Form 10-ID: Statutory regime opt-in forms for Section 115BAA and Section 115BAB respectively. Must be filed before the Section 139(1) ITR due date. One-time, irrevocable election.

DPIIT and IMB: Two separate startup approvals. DPIIT (Department for Promotion of Industry and Internal Trade) recognition makes a startup eligible for various benefits. IMB (Inter-Ministerial Board) certification is a separate, mandatory approval to claim Section 80-IAC tax holiday - only about 1.8 percent of DPIIT-recognised startups hold IMB.

Our Process

7-Step ITR-6 Filing Procedure

The Patron workflow runs on the Income Tax e-filing portal with mandatory DSC verification, audit co-ordination, regime arbitrage memo and MAT computation. Each step is owned by a named senior corporate tax CA with documented hand-off, ensuring Form 10-IC/10-ID, Form 3CEB and Form 3CD are filed within their respective statutory windows.

Step 1

Audit Coordination

Receive audited financials (Schedule III balance sheet, P and L, cash flow, notes) and Form 3CD tax audit report from the statutory auditor. Reconcile Form 3CD with books and GST 9C. Tax audit report due 30 September 2026, one month before ITR.

Audit reconciled 3CD aligned

Common Company ITR-6 Mistakes and How We Avoid Them

Challenge	Impact	How Patron Accounting Solves It
Switching to Section 115BAA before exhausting 80-IAC	Section 115BAA blocks Section 80-IAC, 80-IA, 80-IB deductions. Many founders opt into 115BAA for a 3 percent rate cut and forfeit Rs 30 to 100 lakh of 80-IAC tax holiday. The election is irrevocable.	Patron runs a 10-year tax projection comparing standard plus 80-IAC plus MAT credit vs 115BAA. Both paths modelled before filing Form 10-IC.
MAT credit lost on Section 115BAA opt-in	Companies with accumulated MAT credit under Section 115JAA lose it when opting for 115BAA. CBDT Circular 29/2019 confirms MAT credit becomes unusable.	Patron computes MAT credit balance against expected normal tax for the next 5 years before recommending regime switch. Credit utilisation schedule overlaid on regime decision.
Transfer pricing errors triggering Section 271AA/271G penalties (up to 2 percent of transaction value)	Form 3CEB filed late, Schedule TPSA mismatches with the master file, or missing Section 92D documentation triggers penalty up to 2 percent of the transaction value under Sections 271AA and 271G.	Patron co-ordinates the Section 92E accountant, Form 3CEB filing, Schedule TPSA reporting and Section 92D documentation review end to end.
DPIIT startup claiming 80-IAC without IMB certification	DPIIT recognition alone is NOT sufficient for 80-IAC. The Inter-Ministerial Board (IMB) certificate is a separate, mandatory approval. Only about 3,700 of 207,135 DPIIT-recognised startups hold IMB approval.	Patron pre-screens IMB application 6 to 9 months before the planned 80-IAC claim year. Filing without IMB certification results in disallowance at Section 143(3) scrutiny.
Low-profit year selection for 80-IAC	Taxpayers choose Year 4, 5, 6 of incorporation for 80-IAC instead of waiting for Year 7, 8, 9 when profits typically peak. The year selection is irrevocable once filed in ITR-6.	Patron 80-IAC year-selection memo locks in the most tax-efficient 3-year window based on profit projections, board-approved budgets and growth trajectory.
Section 79 shareholding test failure for closely-held companies	Closely-held company carry-forward losses lapse under Section 79 if more than 49 percent of voting power changes hands. Common in VC funding rounds without Section 79 carve-out.	Patron tracks shareholding changes across funding rounds. Section 79(2) carve-outs (death, gift, amalgamation, demerger, eligible startup ESOP) documented to preserve carry-forward.
DSC mismatch or expiry at filing time	An expired DSC, or DSC issued to a different PAN than the e-filing portal registration, makes ITR-6 invalid. Aadhaar OTP and net banking EVC are not permitted for companies.	Patron pre-files DSC validity check 30 days before the Section 139(1) due date. DSC-PAN match verified against e-filing portal registration.
Schedule FA, Schedule TR, Schedule TPSA omissions	Companies with foreign subsidiaries or step-down entities frequently miss Schedule FA disclosure. Schedule TR foreign tax credit not co-ordinated with Form 67. Schedule TPSA misaligned with Form 3CEB.	Patron schedule-completeness checklist covers all 25+ ITR-6 schedules. Foreign asset reconciliation done against consolidation working papers.

Pvt Ltd or OPC - turnover under Rs 5 crore, no TP, no startup deduction	Standard ITR-6 with audit coordination, regime arbitrage, MAT computation, Schedule III reconciliation	Rs 2,999

Pvt Ltd - turnover Rs 5 crore to Rs 50 crore, Section 115BAA opt-in	Includes Form 10-IC filing, 10-year regime projection, MAT credit reconciliation pre-election	Rs 9,999

Foreign Company with Permanent Establishment in India	PE determination, DTAA relief, Form 67 FTC, withholding tax reconciliation, MAT on PE income	Rs 45,000
Tax Audit only (Section 44AB) - quoted separately	Form 3CA-3CD or 3CB-3CD tax audit report; charged separately from ITR filing fee	From Rs 15,000
Patron Accounting Professional Fees	Standard starting price for basic Pvt Ltd or OPC ITR-6; transfer pricing study reports and CBC reports quoted separately based on transaction value and complexity	Starting from INR 2,999 (Excl. GST and Govt. Charges)
