Section 80-IAC and R&D Deductions: The Tax Assumptions That Cost Founders the Most

I assumed DPIIT recognition automatically meant my startup was tax-exempt. It doesn't. Section 80-IAC of the Income Tax Act, 1961 gives eligible startups a 100% tax deduction on profits for any 3 consecutive years within their first 10 years of incorporation — but it requires a completely separate application, reviewed and approved by an Inter-Ministerial Board (IMB), on top of DPIIT recognition. The eligibility bar is real: the entity must be a Private Limited Company, LLP, or (as of a February 2026 notification) a Cooperative Society, incorporated after April 1, 2016, with turnover below the revised ₹200 crore threshold, and genuinely working on innovation rather than a copied business model. According to DPIIT's own disclosures, only around 1.8% of the 2.07 lakh recognised startups in India have actually secured the exemption — it is selective, not automatic. Separately, startups spending on in-house research and development can claim a weighted deduction under Section 35(2AB) for eligible R&D expenditure, and DPIIT-recognised startups issuing shares at fair value are exempt from Angel Tax under Section 56(2)(viib), provided the declaration is filed correctly. This piece breaks down what each provision actually covers, the documents the IMB wants to see, and the assumptions that get founders' applications rejected.
