Wealth-tax settlement applications trigger strict timelines for notice, reports, orders, payment terms and interest on unpaid tax. Section 22D requires the Settlement Commission on receipt of a section 22C application to issue notice, hear the applicant and within prescribed periods either reject or allow the application - failing which it is deemed allowed - send copies of orders to the applicant and Commissioner, call for Commissioner's reports within fixed timelines, declare applications invalid only after hearing, direct further enquiries if necessary, and finally pass settlement orders specifying terms including tax, penalty or interest, payment manner, voidance for fraud, interest on unpaid tax and a six-month rectification window.
