Undisclosed foreign assets can be declared for pre 2016 taxable income within a government notified compliance window. Section 59 permits a person to make a declaration for any undisclosed asset located outside India acquired from income chargeable to tax for assessment years prior to the year beginning 1 April 2016, on or after commencement of the Act but before a date to be notified by the Central Government, subject to the Chapter. The remedy applies where the person failed to furnish a return under section 139, failed to disclose the asset in a return furnished before commencement, or where the asset escaped assessment due to omission or failure to make a return or to disclose material facts.
