Deferred tax on specified securities: payable on earliest of sale, employment cessation, or prescribed holding period expiry. The amendment creates a deferred payment rule under the notice-of-demand framework for income from specified securities and sweat equity shares allotted or transferred by a current employer that is an eligible start-up, making tax or interest payable on the earliest of a prescribed holding-period expiry, the sale of the shares by the assessee, or the assessee ceasing employment with the employer who allotted or transferred the shares.
