26 U.S. Code § 27. Taxes of foreign countries and possessions of the United States
2018—Pub. L. 115–141 amended section generally. Prior to amendment, section consisted of subsecs. (a) and (b) relating to the foreign tax credit under section 901 and the tax credit under section 936, respectively.
1976—Pub. L. 94–455 designated existing provisions as subsec. (a) and added subsec. (b).
For provisions that nothing in amendment by Pub. L. 115–141 be construed to affect treatment of certain transactions occurring, property acquired, or items of income, loss, deduction, or credit taken into account prior to Mar. 23, 2018, for purposes of determining liability for tax for periods ending after Mar. 23, 2018, see section 401(e) of Pub. L. 115–141, set out as a note under section 23 of this title.
 So in original. Probably should be followed by a period.
