What this means
Section 72 of IT Act 1961 (unabsorbed business losses carried forward for 8 assessment years; set off only against PGBP income; return must be filed to carry forward) maps to Section 108 of IT Act 2025. The 8-year carry-forward limit and mandatory return filing condition are 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
This change takes effect from 1 April 2026 (Tax Year 2026-27 onwards). For income earned before 1 April 2026, the old Section 72 continues to apply under the transitional provisions of Section 536 of the IT Act 2025. Returns for FY 2025-26 (AY 2026-27) are filed under the IT Act 1961 — old section numbers apply.
