Gift taxation rules for individuals and HUFs cover cash, property valuation, exemptions, and agreement-date valuation relief. Gift receipts by an individual or Hindu undivided family are taxable as income from other sources where money is received without consideration above the prescribed threshold, or where immovable property or other specified property is received without consideration or for inadequate consideration beyond the threshold. For immovable property, stamp duty value governs taxability, with provision for using the agreement-date value where consideration is paid through specified banking or electronic modes before the agreement date, and for valuation reference where stamp duty value is disputed. The rule excludes gifts from relatives and other specified exempt sources, and defines property and relative for the purpose of gift taxation.
