DPIIT + 80-IAC — the two-step tax holiday
DPIIT recognition is the entry ticket — it's a self-declaration process on startupindia.gov.in with a short product write-up, revenue potential, IP status and incorporation certificate. Recognition is usually granted in 5–15 working days and unlocks angel-tax exemption (56(2)(viib)), 9 labour law self-certifications, fast-track patent examination and access to government tenders reserved for startups.
80-IAC is separate and needs an Inter-Ministerial Board (IMB) certificate. Only recognised startups qualify. If granted, the startup can claim 100% deduction of business profits for any 3 consecutive assessment years out of its first 10 years — most founders time this for years 4-6 when revenue kicks in. Applications go through startupindia.gov.in → IMB approval takes 3-6 months.
