§ 7448. Extension of time for payment

(a) If the Commissioner finds that the payment on the due date of any part of the amount determined by the executor as the tax imposed by this subchapter would result in undue hardship to the estate, he or she may extend the time for payment for a reasonable period not in excess of five years from the date prescribed by section 7447 of this title.

(b) For good cause shown, the Commissioner may extend the time for the payment of any tax liability, but the taxpayer shall pay, at the time the tax liability is paid, without assessment or demand, interest computed at the rate per annum established from time to time by the Commissioner pursuant to section 3108 of this title on the unpaid amount of that tax liability from the time when the liability was originally due to the time of payment. However, no interest shall be required in the case of an extension granted in case of hardship under subsection (a) of this section. (Added 1969, No. 269 (Adj. Sess.), § 1, eff. date, see note under § 7401 of this title; amended 1979, No. 105 (Adj. Sess.), § 16; 1981, No. 191 (Adj. Sess.), § 7.)
