Iowa is dramatically simplifying its income tax — moving to a 3.8% flat rate by 2025, down from a prior 9-bracket system. One of the most employer-friendly states in the Midwest. Rippling handles IA DOR, Iowa Workforce Development, and workers’ comp compliance.
Iowa is a major Midwestern economy with strengths in agriculture, food processing, manufacturing, financial services (Des Moines is a major insurance hub), and a growing technology sector. Iowa is dramatically reducing its income tax: the prior 9-bracket system (top rate 8.53%) is being phased out, with a 3.8% flat rate effective January 1, 2025. Iowa has no state-mandated paid family leave and is a right-to-work state. Des Moines and Cedar Rapids are the primary employer markets.

Iowa has dramatically simplified from a 9-bracket system (top 8.53%) to a flat rate. IA withholding remitted to IA DOR. Annual IA W-2 reconciliation.
Final Pay: Iowa requires final pay on the next regularly scheduled payday. Accrued vacation: Iowa Wage Payment Collection Law treats promised vacation as wages if the employer’s policy provides for payout. A written forfeiture policy is generally enforceable in Iowa.
Iowa is eliminating its prior 9-bracket income tax system (top rate 8.53%) and replacing it with a flat rate: 4.4% for 2024 and 3.8% from January 1, 2025. This makes Iowa one of the most dramatic tax simplification stories in recent US state tax history. The 3.8% flat rate will be among the lowest in states with an income tax. Rippling updates Iowa withholding annually as the rate changes.
Des Moines is the insurance capital of the US, hosting the headquarters of Principal Financial, Nationwide, EMC Insurance, and dozens of other major insurers. The financial services and insurance sector drives strong professional employment demand in Des Moines, with salaries benchmarking to the broader Midwest financial services market rather than general Iowa averages.
Iowa requires workers’ compensation coverage for most employers with employees. Employers may purchase through private insurers or apply for self-insurance approval. The Iowa Division of Workers’ Compensation administers the system. Iowa’s workers’ comp system is considered moderately employer-friendly.
Iowa’s minimum wage is $7.25/hour — matching the federal minimum. Iowa preempted local minimum wage ordinances in 2017 (several Iowa counties had enacted local minimums). The federal floor applies statewide.
