Any alien described in subdivision (i) or (ii) of this subparagraph who is in default in making return of, or paying, income tax for any taxable year shall, in addition, file with the district director any returns which have not been made as required and pay to the district director the amount of any tax for which he is in default. Upon compliance by an alien with the foregoing requirements of this subparagraph, the district director shall execute and issue to the alien the certificate of compliance attached to Form 2063. The certificate of compliance so issued shall be effective for all departures of the alien during his current taxable year, subject to revocation upon any subsequent departure should the district director have reason to believe that such subsequent departure would result in jeopardy. The statement required of a resident alien under this subparagraph, if made before January 21, 1961, with respect to a departure after January 20, 1961, may be made on a Form 1040C in lieu of a Form 2063.
Upon compliance by the alien with the foregoing requirements of this subdivision, and the payment of any income tax for which he is in default, the district director shall execute and issue to the alien the certificate of compliance on the duplicate copy of Form 1040C. The certificate of compliance so issued shall be effective for all departures of the alien during his current taxable year, subject to revocation by the district director upon any subsequent departure if the taxable period of the alien is terminated on such subsequent departure.
Upon compliance with the foregoing requirements of this subdivision, and payment of the income tax required to be shown on the returns filed pursuant to (a) and (b) of this subdivision and of any income tax due and owing for prior years, the departing alien will be issued the certificate of compliance on the duplicate copy of Form 1040C. The certificate of compliance so issued shall be effective only for the specific departure with respect to which it is issued. A departing alien may postpone payment of the tax required to be shown on the returns filed in accordance with (a) and (b) of this subdivision until the usual time of payment by furnishing a bond as provided in § 301.6863-1 .
