Indian income tax / Startup tax incentives
Section 80-IAC: 100% Tax Deduction for Eligible Startups
Section 80-IAC of the Income-tax Act, 1961 provided a 100% deduction of qualifying business profits for three consecutive assessment years, chosen within the first ten years of an eligible startup. It applied to qualifying companies and limited liability partnerships (LLPs), subject to incorporation dates, turnover limits, certification and other conditions.
What was Section 80-IAC?
Section 80-IAC was a profit-linked incentive for an eligible startup conducting an eligible business. Unlike a deduction for startup investment or expenditure, it operated on the profits and gains derived from the qualifying business. The deduction was subject to the overall statutory framework for computing income and to the applicable restrictions incorporated from Section 80-IA.
Deduction amount and period
| Feature | Amended Section 80-IAC position under the 1961 Act |
|---|---|
| Deduction | 100% of profits and gains from eligible business, subject to conditions |
| Duration | Any three consecutive assessment years |
| Choice of years | Within ten years beginning with the year of incorporation |
| Entity type | Eligible company or limited liability partnership (LLP) |
| Incorporation | On or after 1 April 2016 but before 1 April 2030 |
| Turnover ceiling | Not exceeding Rs. 100 crore in the previous year relevant to the assessment year of the claim |
| Certification | Certificate of eligible business from the Inter-Ministerial Board of Certification |
The three years must be consecutive, not simply the three highest-profit years. A startup may elect a qualifying three-year block within the ten-year statutory window; losses and other restrictions can affect the actual deduction.
Eligibility conditions for startup tax deduction
1. Eligible legal form and incorporation
For Section 80-IAC, an eligible startup had to be a company or LLP incorporated within the statutory date range. An ordinary partnership firm or sole proprietorship did not qualify merely because it was recognised as a startup under another government scheme. The incorporation date condition was extended by the Finance Act, 2025 to cover incorporations before 1 April 2030.
2. Eligible business
The statutory definition included a business engaged in innovation, development or improvement of products, processes or services, or a scalable business model with high potential for employment generation or wealth creation. The applicant had to establish that its activities fell within the definition and that the profits arose from that eligible business.
3. Rs. 100 crore turnover limit
The statutory turnover threshold was Rs. 100 crore for the previous year relevant to the assessment year for which the deduction was claimed. This is distinct from the wider DPIIT startup-recognition turnover thresholds, which may differ. Recognition as a startup does not by itself establish eligibility for the tax deduction.
4. Inter-Ministerial Board certificate
The entity had to hold a certificate of eligible business from the notified Inter-Ministerial Board (IMB) of Certification. DPIIT recognition and IMB tax certification are not interchangeable. A CBDT clarification dated 13 January 2025 states that the benefit is available from IMB approval and that the selected three consecutive years must fall within the ten-year window and on or after the year of certification.
5. No splitting or reconstruction of existing business
Under subsection (3), the startup generally could not be formed by splitting up or reconstructing an existing business, subject to the specific statutory exception involving re-establishment or revival under Section 33B.
6. Restriction on previously used machinery
A startup generally could not be formed by transferring previously used machinery or plant to the new business. The law provided specific exceptions for certain imported machinery used outside India and a deeming relaxation where previously used machinery or plant transferred did not exceed 20% of the total value of machinery or plant used in the business.
Important statutory definitions
Eligible business
A business of an eligible startup involving innovation, development or improvement of products, processes or services, or a scalable business model with high potential for employment generation or wealth creation.
Eligible startup
A qualifying company or LLP engaged in eligible business, meeting the incorporation-date, turnover and IMB-certificate conditions in the statute.
Limited liability partnership
An LLP within the meaning of Section 2(1)(n) of the Limited Liability Partnership Act, 2008.
Gross total income
Broadly, total income computed before allowing deductions under Chapter VI-A, subject to the applicable statutory definition and computation provisions. A profit-linked deduction cannot be treated as an unconditional cash grant or as a deduction from turnover.
How to apply and claim the benefit
- Confirm that the entity is a company or LLP incorporated within the statutory dates and conducting an eligible business.
- Obtain DPIIT startup recognition through the applicable official process.
- Apply for IMB certification for Section 80-IAC through the Startup India portal and retain the approval documents.
- Check the turnover ceiling, eligible-business profit computation and machinery/reconstruction conditions for each proposed deduction year.
- Select three consecutive qualifying years within the ten-year incorporation window, respecting the timing of IMB approval and any applicable transitional law.
- Maintain audited financial records and furnish the applicable audit report and return particulars as required by the governing law and filing procedure.
Subsection (4) incorporated Section 80-IA(5) and (7) to (11), including separate eligible-business profit computation, audit and transfer-pricing or related-party safeguards. Tax-return filing requirements must be checked for the relevant tax year.
Example: calculating the 100% deduction
Assume a qualifying company was incorporated in financial year 2021-22, received its IMB certificate in time and elected a valid block of three consecutive assessment years. If its eligible-business profits were Rs. 40 lakh, Rs. 65 lakh and Rs. 90 lakh in those three years, the indicative deductions could be Rs. 40 lakh, Rs. 65 lakh and Rs. 90 lakh, respectively, subject to the applicable tax law, loss adjustments, eligible-income computation and all statutory conditions. The total indicative deduction across the block would be Rs. 1.95 crore. The figures do not imply that unrelated income is deductible.
DPIIT recognition versus Section 80-IAC eligibility
DPIIT startup recognition serves a broader government policy framework, whereas the income-tax deduction imposed its own legal-form, turnover, IMB certification and timing requirements. As explained by the Income Tax Department's startup taxation guidance, an entity recognised by DPIIT does not automatically qualify for the Section 80-IAC profit deduction.
Income-tax Act, 2025 and claims after 1 April 2026
The Income-tax Act, 2025 replaced the 1961 Act with effect from 1 April 2026. This article preserves the history and amended rules of Section 80-IAC under the 1961 Act; it does not assert that the same section number or every condition remains unchanged in the new statute. For tax year 2026-27 and later, consult the operative startup deduction provisions, definitions, commencement rules and transitional arrangements in the 2025 Act, and confirm the current prescribed forms and certification procedures.
