Income from Other Sources deductions: specified allowances, strict conditions, and express disallowances for dividend and fund income. Deduction under the head 'Income from Other Sources' allows specified deductions for interest on securities, employee contributions to welfare funds, rental and hiring income, family pension, residual revenue expenditure, interest on compensation, commuted pension from specified funds, and death-cum-retirement gratuity. The provisions also impose conditions such as crediting employee contributions by the return-filing due date, restricting residual deductions to revenue expenditure wholly and exclusively incurred for earning the income, and applying fixed or full deductions in specified cases. Dividend income and certain mutual fund or specified company income are subject to express disallowance rules.
