Deduction for retirement, insurance and housing contributions conditioned by prescribed limits and taxed on premature withdrawal. The Schedule prescribes deductible payments for life insurance premiums, annuity and pension contributions, provident and recognised funds, unit-linked and notified mutual fund investments, specified deposits and bonds, tuition fees for two children, and payments toward purchase or construction of a residential house, subject to notification, naming, and instrument-specific limits. It sets percentage and instrument-based eligibility limits for insurance premiums and pension contributions, excludes loan repayments from 'contribution,' and provides reversal rules whereby deductions previously allowed are disallowed and treated as income if contracts are terminated, participation ceases prematurely, property is transferred within prescribed holding periods, or subscribed securities are disposed of within a short timeframe, with specified taxation mechanics on withdrawal or receipt.
