Iowa UI Contribution Rate Table and Average Tax Rate
Iowa Law requires Iowa Workforce Development to establish a tax table for each year. The unemployment insurance rate table trigger formula is primarily based on the UI trust fund balance and covered wage growth. The formula is designed to enable the trust fund to keep pace with potential liabilities as covered unemployment and wages grow. This dataset contains the contribution rate table and the average tax rate for employers subject to the Iowa Unemployment Insurance system.
The average contributions rates are computed based on the combined total of contributions to the Unemployment Insurance Trust Fund and the Iowa Unemployment Compensation Reserve Fund. The average tax rates can vary within a given rate table due to fourth quarter lag, different rates of taxable wage growth, changes due to appeals, etc.
