Iowa Paycheck Calculator 2026

A paycheck in Iowa passes through the same federal deductions as anywhere else: federal income tax based on the W-4 you filed, Social Security at 6.2% up to the $184,500 wage base, and Medicare at 1.45% on every dollar with no ceiling. On top of those, Iowa applies a single state income tax rate of 3.8% to your taxable wages, so the state slice is easy to estimate once you know your gross pay.

What makes the Iowa side simple is the absence of brackets. Whether you earn $40,000 or $400,000, the marginal and effective state rate is the same 3.8% after the standard deduction, which is $16,100 for a single filer. Iowa runs no state disability insurance and no paid-family-leave payroll tax, so you won't see those line items. Pre-tax contributions, such as 401(k) deferrals up to $24,500 and health premiums, shrink the wages that both federal and state tax touch, which is the main lever most workers have over net pay.

On a $60,000 salary, Iowa's flat 3.8% income tax comes to about $1,628 a year for a single filer after the state's own deductions and exemptions — on top of $4,590 in federal FICA, which is the same in every state. 7 of the 42 states that tax income have a lower top rate than Iowa's 3.8%.

The state minimum wage is $7.25/hr , matching the federal floor of $7.25 — about $15,080 a year at 40 hours a week. There is no state disability or paid-family-leave deduction, so nothing beyond income tax and FICA comes out at the state level. Local jurisdictions add their own layer on top — see the note below.
