Specified income tax exemption protects welfare board receipts subject to non-commercial operations, unchanged income character, and return-filing compliance. Tax exemption is granted to the Kerala Headload Workers Welfare Board, Kochi, for specified income under Section 10(46) of the repealed Income-tax Act, 1961, pursuant to the saving and transitional provisions of the Income-tax Act, 2025. Exempt income includes government grants and loans, statutory levies, registration fees, employer deposits, member contributions, specified wages, and related interest. The Board must not undertake commercial activity, must retain the same activities and income character, and must file the prescribed income-tax return. Non-compliance may result in penal action and withdrawal of exemption.
