A bill for an act relating to unemployment insurance taxes on employers. (Formerly SF 504, SSB 1173.) Effective date: 07/01/2025.
Summary
Senate File 607 revises Iowa’s unemployment insurance tax system for employers. The bill lowers the amount of wages subject to unemployment insurance contributions by changing the taxable wage base from 66 2/3 percent to 33 1/3 percent of the statewide average weekly wage, which reduces the payroll amount on which employers pay unemployment taxes. It also changes the starting contribution rates for newly subject employers, including different treatment for nonconstruction employers versus construction and landscaping employers, and updates the unemployment reserve fund ratio thresholds and contribution rate tables used to set employer tax rates.
The bill also makes technical and structural changes to how experience-rated employer contribution rates are calculated, including revised benefit ratio rank tables and related formulas. In addition, it adds a policy statement that any employer savings from the act should be used either to increase employee salaries or benefits or to offset seasonal unemployment through alternatives to unemployment benefits. The bill is effective July 1, 2025.
Impact
SF 607 amends Iowa Code chapter 96, which governs unemployment insurance taxes and employer contribution rates. Its main legal effect is to reduce the taxable wage base and alter the rate-setting framework for employers, which should lower unemployment insurance tax liability for many employers and change how the Department of Workforce Development calculates contribution rates, reserve fund ratios, and benefit ratio ranks. The bill affects employers generally, with specific provisions for newly covered nonconstruction, construction, and landscaping employers.
Sentiment
The available voting history suggests the bill had meaningful support but also notable opposition. It passed the Senate Ways and Means Committee 11-5, indicating support from a majority of committee members but not unanimity. On the floor, the bill ultimately passed both chambers, but the recorded votes on amendments and final passage show a divided legislature, with several close or split votes before final approval. Overall, the sentiment appears generally favorable among supporters of employer tax relief, while a substantial minority opposed or sought to modify the bill.
Contention
The main point of contention appears to be the size and structure of the unemployment insurance tax reduction, especially the reduction in the taxable wage base and the revised contribution rate tables. Opponents likely objected to lowering employer contributions and changing the reserve fund calculations, which could affect the unemployment insurance trust fund’s revenue and long-term solvency. The differing votes on amendments suggest disagreement over how the bill should be adjusted before passage, while supporters appear to have favored reducing employer costs and providing savings that could be redirected to wages, benefits, or seasonal employment needs.
