Employer's Unemployment Insurance Tax Account
IWD's Unemployment Insurance (UI) Division maintains an account for each employer covered by the Iowa Employment Security law. Your business will be assigned an employer account number at the time your liability status is established. This number should appear on all correspondence and forms that you submit to Iowa Workforce Development. New accounts are created online at www.myiowaui.org.
Unemployment Insurance Tax Rate Tables
Iowa law stipulates that UI taxes may be collected from employers under four different tax rate tables, and each tax rate table has 9 rate brackets (or ranks). Rates vary from 0.000% to 5.400%.
The tables were established to help maintain the stability of the UI Trust Fund. As such, a formula in the law mandates movement to a table that collects more revenue when the balance in the UI fund is low and movement to a table collecting less revenue when the balance is high.
The rate table effective for any given year is applicable to all participating employers. The table in effect for all private employers for 2026 is Table D, the lowest rate allowed by law.
New Employers
With the exception of new construction employers, new employers are assigned the rate from rank 4 of the table in effect (the rank is not to go below 1.000%). New construction employers are assigned the rate from rank 9 of the table in effect. The Historical Unemployment Insurance Tax Rate Table provides current and past rate information.
Employer Notification of UI Tax Rates
Rate tables are updated annually. During November, a Notice of Tax Rate is mailed to each employer indicating the tax rate to be use for the coming year.
Employers have 30 days to appeal their Notice of Tax Rate if they believe an error occurred in calculating the rate. The following links provide additional information on the rate computations and appeal rights:

State Unemployment Tax Act Avoidance
State Unemployment Tax Act (SUTA) avoidance (or "dumping") is a form of tax avoidance or UI tax rate manipulation through which employers dump higher UI taxes by attempting to obtain a lower rate.
SUTA dumping involves the manipulation of an employer’s UI tax rate and/or payroll reporting to owe less in UI taxes.
