Revenue Ruling 2020-08 suspends Rev. Rul. 71-533 pending reconsideration of whether the ten-year limitations period provided by section 6511(d)(3)(A) of the Internal Revenue Code applies to claims for refund or credit of an overpayment resulting from a foreign tax credit (FTC) carryback arising as a result of a net operating loss (NOL) carryback from a subsequent year.  As part of this reconsideration, Rev. Rul. 68-150 is also being reconsidered and is suspended with respect to adjustments that arise from a change to the FTC limitation, including as the result of the correction of mathematical errors or the application of an NOL carryback.
