100. (1) Where any private company is wound up ¹[or has discontinued business for three successive years] and any tax assessed on the company, whether before, or in the course of, or after its liquidation, in respect of any income of any income year cannot be recovered, every person who was, at any time during the relevant income year, a director of that company, shall, notwithstanding anything contained in ²[the Companies Act, 1913 (VII of 1913) or কোম্পানী আইন, ১৯৯৪ (১৯৯৪ সনের ১৮ নং আইন)], be jointly and severally liable to pay the said tax and shall, for the purposes of recovery thereof, be deemed to be an assessee in respect of such tax; and the provisions of this Ordinance shall apply accordingly.

(2) Notwithstanding the provisions of sub-section (1), the liability of any person thereunder in respect of the income of a private company shall cease if he proves to the Deputy Commissioner of Taxes that non-recovery of tax from the company cannot be attributed to any gross neglect, misfeasance or breach of any duty on his part in relation to affairs of the company.
