Filing an income tax return is mandatory for every startup-even those that are pre-revenue, loss-making, or in stealth mode. But for startups that have navigated the DPIIT recognition and Section 80-IAC certification process, the ITR is where you actually claim the tax holiday and lock in the financial benefit. Filing incorrectly-or late-can permanently forfeit the 80-IAC exemption for that year, eliminate loss carry-forward eligibility, and trigger notices that consume founder time for months.
This guide covers every startup-specific ITR rule and relaxation in 2026: the Section 80-IAC claim mechanics in ITR-6, the impact of angel tax abolition on ITR disclosures, ESOP perquisite deferral reporting, the Section 79 loss carry-forward relaxation, new Schedule 80-IAC in the revised ITR-6, and the Tax Year transition under the IT Act, 2025. For startups managing income tax return filing (know more), getting these startup-specific elements right is the difference between Rs 15+ lakh in tax savings and a wasted opportunity.
Six Startup-Specific Rules in 2026
1. Section 80-IAC: 100% Profit Exemption (3 Years Out of 10)
The most powerful startup tax incentive. DPIIT-recognised startups (Pvt Ltd or LLP) with IMB certification can claim 100% deduction on profits for any 3 consecutive financial years within the first 10 years of incorporation.
| Parameter | Detail |
|---|---|
| Eligible entities | Private Limited Company or LLP only. Partnerships NOT eligible. |
| Incorporation window | After 1 April 2016, before 1 April 2030 (extended by Budget 2025) |
| Turnover limit | Annual turnover must not exceed Rs 100 crore in any FY since incorporation |
| How to claim in ITR | File ITR-6 (companies) or ITR-5 (LLPs). Complete Schedule 80-IAC (new). Attach IMB certificate reference. Claim deduction under Chapter VIA. |
| Strategic tip | Choose 3 profitable years, not early loss-making years. You have a 10-year window to optimise. |
| Approvals as of May 2025 | Over 3,700 startups approved out of 1.5 lakh+ DPIIT-recognised. 187 approved in April 2025 alone. |
For entities using tax audit services (know more), the tax auditor must verify 80-IAC eligibility and ensure the claim is correctly reflected in Form 3CD.
2. Angel Tax Abolished (Section 56(2)(viib))
From FY 2025-26 onwards, angel tax has been abolished for all classes of investors-domestic and foreign. This means:
- No Schedule 56(2)(viib) disclosures required in the ITR for share premium received
- No valuation report or Form 2 declaration needed for angel tax exemption
- Investments at any premium are accepted without triggering income tax on the startup
- The DPIIT 2026 notification formally omits all angel tax references
ITR impact: Startups that previously reported share premium under “Income from Other Sources” with an exemption claim no longer need to make this disclosure for FY 2025-26 onwards. However, the share premium must still be correctly recorded in the balance sheet and financial statements.
3. ESOP Perquisite Deferral (Section 192(1C))
Employees of eligible startups (DPIIT-recognised + Section 80-IAC certified) benefit from deferred TDS on ESOP perquisites. In the ITR, this affects:
- Year of allotment: The ESOP perquisite may not appear in Form 16 if TDS is deferred. The startup need not include deferred perquisite in the employee’s salary TDS.
- Year of trigger event: When the deferral triggers (48 months / sale / cessation), the perquisite must be reported in that year’s Form 16 and the employee’s ITR.
- Startup’s ITR: The startup must track deferred ESOP perquisites as a contingent TDS liability in its books and disclose them in notes to financial statements.
4. Section 79: Loss Carry-Forward Relaxation
Normal companies can carry forward losses only if 51% or more of voting power is held by the same shareholders. For DPIIT-recognised startups, Section 79 is relaxed:
- Startup relaxation: Losses can be carried forward even if shareholding changes (founder dilution, VC investment rounds) as long as ALL original shareholders continue to hold shares (even if their percentage decreases).
- Practical impact: Series A/B/C fundraising dilutes founders but does NOT prevent loss carry-forward as long as no original shareholder exits completely.
- ITR reporting: In ITR-6, the startup must disclose the shareholding pattern and confirm Section 79 compliance. The DPIIT recognition number must be quoted.
5. Self-Certification on 9+3 Laws
While not directly an ITR matter, self-certification on 9 labour laws and 3 environmental laws reduces the compliance burden that indirectly affects ITR preparation-fewer inspection findings, fewer contingent liabilities to disclose.
6. Reduced IP Filing Fees
DPIIT-recognised startups pay 80% reduced patent fees and 50% reduced trademark fees. These reduced costs are deductible business expenses in the ITR, lowering taxable income. For startups managing company registration (know more) alongside IP strategy, claiming these expenses in the ITR is a minor but cumulative benefit.
Step-by-Step ITR Filing for Startups
- Complete books of accounts and get them audited. Statutory audit under Companies Act (mandatory for all companies). Tax audit under Section 44AB (if turnover exceeds Rs 1 crore / Rs 10 crore). The audit report must be filed before the ITR.
- Reconcile financial statements with GST and TDS data. Revenue per books vs GSTR-9 vs ITR must match. TDS credits (Form 26AS/AIS) must reconcile with books. Discrepancies trigger notices. For startups using professional accounting services (know more), this reconciliation is a standard pre-filing step.
- Compute total income. Income under all heads: business income, capital gains (share sales, asset disposal), other sources (interest, dividends). Apply depreciation. Carry forward and set off losses (Section 79 compliance for startups).
- Apply Section 80-IAC deduction (if eligible). If the startup has IMB certification and is claiming the tax holiday for this year, deduct 100% of eligible business profits under Chapter VIA. Complete Schedule 80-IAC in ITR-6 with DPIIT recognition number and IMB certificate details.
- Compute tax liability. Apply corporate tax rates (25% for companies with turnover ≤ Rs 400 crore, or 22% under Section 115BAA). Add surcharge and cess. Credit TDS, advance tax, and self-assessment tax. For startups under 80-IAC: tax on non-exempt income only (capital gains, other sources).
- File ITR-6 (companies) or ITR-5 (LLPs) on the e-filing portal. Complete all applicable schedules. Upload audit reports (UDIN mandatory). Digitally sign with DSC. Submit.
- E-verify within 30 days. Use DSC, Aadhaar OTP, net banking, or EVC. Without verification, the ITR is treated as not filed.
- Maintain documentation. Keep DPIIT certificate, IMB approval, board resolutions, audited financials, tax audit report, ESOP records, shareholding pattern, and Section 79 compliance documentation. These may be requested during assessment. For startups managing GST registration (know more) alongside ITR, GST return data should reconcile with the ITR turnover disclosure.
New in ITR-6 for 2026: Startup-Specific Schedules
| New/Updated Schedule | What It Requires |
|---|---|
| Schedule 80-IAC (New) | DPIIT recognition number, IMB certificate number, date of approval, eligible business details, profit computation for exemption, 3-year selection window details. |
| Startup Recognition Disclosure | DPIIT recognition status (Yes/No), recognition number, date of recognition. |
| Form-2 Declaration Disclosure | Whether Form-2 declarations have been filed by the startup (relevant for share capital transactions). |
| MSME Dues Disclosure | Amounts payable to Micro and Small Enterprises beyond the prescribed 45-day timeline. Affects deductibility of the expense. |
| GST Turnover Reporting | Disclosure of turnover/gross receipts as reported in GST returns-must reconcile with ITR revenue figure. |
Due Dates for Tax Year 2026-27
| Deadline | Applicable To |
|---|---|
| 31 July 2026 | Companies/LLPs NOT subject to tax audit (turnover below audit threshold) |
| 31 October 2026 | Companies/LLPs subject to tax audit (most startups with turnover > Rs 1 crore or requiring audit under Companies Act) |
| 30 November 2026 | Companies required to furnish transfer pricing report (international transactions) |
| 31 December 2026 (belated) | Belated return filing-penalty applies, loss carry-forward forfeited |
Critical for 80-IAC startups: Late filing invalidates the 80-IAC claim for that year. You cannot claim the tax holiday in a belated return. File on time or lose the exemption permanently for that year.
Common Mistakes Startups Make in ITR Filing
Mistake 1: Not filing ITR because the startup has no revenue. Every company and LLP must file ITR even with zero revenue and zero income. NIL returns are mandatory. Non-filing triggers Section 234F penalty (up to Rs 5,000), risk of MCA strike-off, and inability to carry forward losses.
Mistake 2: Claiming 80-IAC in loss-making years. The 80-IAC exemption is 100% of profits. If there are no profits, there’s nothing to exempt. Claiming in loss years wastes one of the 3 available years. Choose profitable years strategically.
Mistake 3: Not completing Schedule 80-IAC in ITR-6. Even if you have the IMB certificate, the claim must be made in the ITR by completing the Schedule 80-IAC with all required details. Simply having the certificate is not enough-the deduction must be claimed in the return.
Mistake 4: Filing late and losing loss carry-forward. Business losses (except house property losses) cannot be carried forward if the return is filed after the due date. For pre-profit startups, timely filing preserves losses worth crores that can be set off against future profits.
Mistake 5: Not reconciling TDS credits with Form 26AS/AIS. Startups often have TDS deducted by clients, banks, and on payments received. Not reconciling Form 26AS/AIS with the ITR creates credit mismatch notices. Download AIS before filing and ensure all credits are claimed.
Key Takeaways
ITR filing for startups in 2026 involves six special rules: Section 80-IAC tax holiday (100% profit exemption for 3 years, only Pvt Ltd/LLP, IMB certification required, claim in Schedule 80-IAC), angel tax abolition (no more Section 56(2)(viib) disclosures from FY 2025-26), ESOP perquisite deferral (track and report when trigger event occurs), Section 79 loss carry-forward relaxation (shareholding change allowed if all original shareholders remain), self-certification on 9+3 laws, and reduced IP filing fees as deductible expenses.
The IT Act, 2025 introduces the Tax Year concept (replacing Assessment Year), new ITR-6 schedules (Schedule 80-IAC, Startup Recognition Disclosure, MSME Dues, GST Turnover Reporting), and IT Rules 2026 form renumbering. The due date for audit-subject companies is 31 October 2026. Late filing forfeits both the 80-IAC exemption and loss carry-forward-the two most valuable startup tax benefits.
For startups, the ITR is not just compliance-it is the vehicle for claiming the tax holiday, preserving loss carry-forward, and building a clean compliance record that investors verify during due diligence. Over 3,700 startups have 80-IAC certification, but many fail to correctly claim the exemption in the ITR. Professional ITR filing ensures these startup-specific elements are handled correctly.
