Deduction for investment in new equity shares allows a fifty-percent cost deduction with recapture on early disposal. A new deduction permits eligible individual, HUF and certain co-owned associations to claim fifty percent of the cost of qualifying equity shares acquired from taxable income, subject to an aggregate cost ceiling and specification where the ceiling is exceeded. 'Eligible issue of capital' requires a first-time public issue by a public company carrying specified business objects or approved housing-finance activity, public subscription, and compliance with prescribed conditions; converted private companies and premium issues are excluded. Deduction is limited to shares subscribed via public offer, promoter reservation, or purchase from underwriters, with a five-year recapture taxing half the cost if transferred within that period, and such costs excluded from capital-gains allowances.
