General guidance, not legal advice. Every notice is different: go by the section, dates and instructions in the notice itself. Check its DIN with the Authenticate notice/order service on the income tax portal. Section numbers here are from the Income-tax Act, 1961; the Income-tax Act, 2025, in force from 1 April 2026, numbers them differently, so a newer notice may cite another section.
