On June 8, 2021, Governor Kim Reynolds signed 2021 Iowa Acts, Senate File 608. Division II of that legislation made extensive changes to Iowa’s composite return and nonresident withholding requirements for pass-through entities and their nonresident members. These changes apply to tax years beginning on or after January 1, 2022 (“tax year 2022”). This guidance describes those changes. The Department will update tax forms and administrative rules in the near future to implement the composite return changes enacted in Senate File 608 and described in this guidance.
For information on Iowa’s composite return and nonresident withholding requirements for pass-through entities and their nonresident members in effect before tax year 2022, see the IA 1040C (composite individual income tax return for nonresidents), as well as Iowa Administrative Code rule 701—chapter 48 (composite returns) and Iowa Administrative Code rule 701—46.4 (withholding on nonresidents).
