Budget 2026-27 extended the 100% profit-linked tax deduction for DPIIT-recognised startups (incorporated from April 2016) by 5 years under Section 80-IAC. Deep-technology startups operating in AI, biotechnology, and semiconductors received an extended 15-year tax holiday window (up from 10 years). Angel tax, abolished in July 2024, was permanently confirmed as removed. Three separate ₹10,000 crore funds were announced for startups, MSMEs, and biopharma innovation, plus ₹2,000 crore for existing support infrastructure. The budget also offered R&D credits under Section 35(2AB) and grants for AI and 5G development. DPIIT issued new notification redefining startup and deep tech startup recognition criteria, formally recognising deep tech as a distinct category.
