Penalty waiver and prosecution immunity available when tax is paid and cooperation given, unless prosecution had already begun. Rule 44DAC authorises the Dispute Resolution Committee to waive or reduce penalties or grant immunity from prosecution subject to conditions and recorded reasons, only if the applicant has paid the tax due on returned income in full if available and cooperated with the Committee; immunity is barred where prosecution commenced before the application and may be withdrawn if the recipient fails to comply with imposed conditions.
