Deduction restriction for political contributions bars deductions for cash donations under section 80GGC, effective next assessment year. The Bill inserts a proviso disallowing any deduction under the relevant provision in respect of sums contributed by way of cash to political parties or electoral trusts, thereby restricting deductible contributions to non-cash modes of payment; the amendment takes effect from 1 April 2014 and applies to assessment year 2014-15 and subsequent years.
