Direct payment of income-tax requires assessee liability when tax is not deducted and prescribes a timeline for startup equity. Income-tax is payable directly by the assessee when tax is not deducted at source or not deducted in accordance with this Chapter; for specified securities or sweat equity allotted or transferred by an eligible start-up employer, the assessee must pay tax directly within a defined short period after the earliest of a statutory time limit, sale of the security, or cessation of employment; a person required to deduct tax who fails to deduct or remit, where the assessee also fails to pay, is deemed an assessee in default.
