A $100,000 salary in Iowa pays a 3.8% flat state tax on taxable income on top of federal income tax and FICA. The federal 22% marginal bracket applies to a significant portion of taxable income at this level, sitting above the 12% bracket threshold. Iowa transitioned from a progressive structure to a 3.8% flat rate in recent reforms. Many Iowa school districts levy a small income surtax computed as a percentage of state liability, which the calculator engine models in approximate form for Des Moines Public Schools. The calculator below lets you adjust filing status, 401(k) and HSA contributions, and other inputs to see how the take-home shifts.

$100,000 in Iowa FAQ

How is $100,000 after taxes calculated for Iowa?

The calculation applies 2026 federal brackets (top marginal 22% at this income), FICA at 7.65% up to the Social Security wage base of $184,500 in 2026 plus 1.45% Medicare on all wages, and Iowa's 3.8% flat state income tax. The standard deduction of $16,100 for single filers is applied before federal brackets, and Iowa applies its own standard deduction or personal exemption before state brackets where modeled.

What if I contribute to a 401(k) or HSA at this income?

Traditional 401(k) and HSA contributions reduce both federal and Iowa taxable income. At the federal 22% bracket plus Iowa's 3.8% state rate at the top of taxable income, every $1,000 of pre-tax contribution saves approximately $258 in combined tax. The 2026 employee 401(k) limit is $24,500 ($32,500 with the age 50-plus catch-up), and HSA limits are $4,400 self-only or $8,750 family.
