What this means
Section 43CA of IT Act 1961 (where a builder transfers unsold stock at less than stamp duty value, stamp duty value is deemed PGBP income; 110% safe harbour) maps to Section 45 of IT Act 2025. The 110% safe harbour for builders is retained. Verify on the income-tax portal before filing.
Change type — Section renumbered
The section number changed when the IT Act 1961 was reorganised into the IT Act 2025. The substance, rates, thresholds, and conditions are preserved. Any reference to the old section number in contracts, certificates, or returns before 1 April 2026 remains valid under the transitional provisions in §536.
Effective date
