Section 80-IAC of the Income Tax Act provides a 100% deduction of profits from business for any three consecutive Assessment Years out of ten years from the year of incorporation, for eligible startups — those incorporated between April 1, 2016 and April 1, 2025 (extended annually), with a DPIIT certificate, turnover below ₹100 crore in any year. The deduction effectively means zero corporate income tax on the startup's profits for those three years. The reason most startups miss it: they assume that a startup generating losses in early years is not "profitable enough to need this." The correct insight is the opposite — you must plan which 3 years to apply the deduction to maximise the tax saved, based on projected profitability.
Section 80-IAC, Income Tax Act
Where the gross total income of an assessee, being an eligible start-up, includes any profits and gains derived from eligible business, there shall, in accordance with and subject to the provisions of this section, be allowed, in computing the total income of the assessee, a deduction of an amount equal to one hundred per cent of the profits and gains derived from such business for three consecutive assessment years out of ten years beginning from the year in which the eligible start-up is incorporated.
Statutory Reference
Strategic 80-IAC Year Selection
Year 1–3 (Loss Phase)
Apply 80-IAC in years when profit is zero or minimal — you claim the deduction but save nothing. Wasteful allocation. Do not use 80-IAC in loss-making years.
Year 3–5 (First Profitability)
If modest profits in these years and higher profits expected later: consider deferring 80-IAC to the higher-profit years. The deduction is most valuable when the marginal tax rate is highest.
Year 5–7 (Peak Revenue)
Typically the highest-impact 80-IAC window. If the startup reaches ₹10+ crore in annual profit, the 25.17% effective corporate tax rate on ₹10 crore = ₹2.5 crore saved per profitable year. Three years = ₹7.5 crore.
Claiming 80-IAC blindly in Year 1 of profitability is a common mistake. If profits are small in Year 1 but large in Years 3–5, the deduction should be deferred. The 10-year window gives you strategic latitude — use it.

How to Activate 80-IAC for Your Startup
- Confirm DPIIT recognition — the exemption is conditional on a valid DPIIT certificate at the time of claiming the deduction.
- Apply for Inter-Ministerial Board (IMB) certification (a separate step from DPIIT recognition required for 80-IAC).
- Build a 5-year profit forecast to determine the optimal 3-year window for the deduction.
- File the return with the deduction claim along with the required audit report in Form 10CCB.
- If your startup has already passed the incorporation date threshold and you have not applied for DPIIT + IMB certification yet: the window may still be open — check immediately.
- Sami Tax has processed 80-IAC applications for 20+ startups, including navigating the IMB certification process which requires a detailed business case presentation.
