Tax rate amendment sets distinct rates for specified units and for co operative societies under the income tax provision. Amendment replaces a sub clause in section 115JF to fix distinct tax rates: units falling within the first specified class under section 115JC(4) are assigned a lower prescribed rate, and co operative societies within the second specified class under section 115JC(4) are assigned a higher prescribed rate; the substitution takes effect from the commencement of the fiscal year beginning 1st April, 2023.
