Deduction under Section 35AC: government approved social welfare projects specified with capped allowable costs for tax relief. The Central Government, on the Committee's recommendation, approves institutions and specifies eligible projects or schemes under Section 35AC, listing for each the estimated project cost and the maximum portion of that cost allowable as deduction; the tabular approval sets project descriptions, cost ceilings (including corpus where specified) and applies for the stated three year financial period, subject to later substitutions recorded in the notification notes.
