Accumulation for charitable purposes: prescribed-form filing required to claim exemption on accumulated income before return due. Exemption is available where income is accumulated or set apart for specific charitable or religious purposes in India provided a prescribed statement identifying purpose and period is furnished before the prescribed deadline, the accumulated sums are invested in specified modes, and not donated to another trust; periods during which application was prevented by court order are excluded. Failure to furnish the statement or to file the return by the due date results in denial of the accumulation benefit and taxation of the income.
