How do I convert an hourly wage to an annual salary in Iowa?

Multiply your hourly rate by the hours you work per week, then by 52 weeks. For example, $25 per hour at 40 hours per week is $25 × 40 × 52 = $52,000 gross per year. This tool does that and then subtracts Iowa state income tax and FICA to show your real take-home pay.

What is Iowa's income tax rate?

Iowa moved to a flat individual income tax of 3.8% for tax year 2025, replacing its old graduated brackets. The flat rate applies to taxable income after the standard deduction, so a worker's effective state rate is a little below 3.8% once the deduction is counted.

Does Iowa have local income taxes?

Some Iowa school districts levy a school district surtax, which is a percentage of your state income tax, not your income. This calculator models only the statewide flat income tax plus FICA, so add any district surtax separately if it applies to you.

What is FICA and why is it deducted?

FICA is the federal payroll tax for Social Security (6.2% up to the annual wage base) and Medicare (1.45% on all wages, plus 0.9% above $200,000). It is the same in every state and is withheld from every paycheck on top of income tax.

Does this include federal income tax?

No. This calculator shows Iowa state income tax and FICA only. Your federal income tax withholding depends on your W-4, filing status, and credits, so your actual paycheck will be lower than the figure shown here once federal tax is withheld.

Need to turn an hourly wage into a yearly salary and see what actually lands in your Iowa paycheck? This calculator annualizes your hourly rate, then applies Iowa’s flat 3.8% income tax, the standard deduction, and FICA (Social Security + Medicare) to estimate real take-home pay per year, month, and bi-weekly period.

How it works

First the tool builds gross annual salary from your hourly inputs:

Gross annual = hourly rate × hours per week × 52

Then it computes Iowa state tax on income after the standard deduction and federal FICA:

Iowa tax = (gross − standard deduction) × 3.8% FICA = Social Security (6.2% to wage base) + Medicare (1.45% + 0.9% surtax over $200k) Net = gross − Iowa tax − FICA

Iowa’s 2025 reform replaced graduated brackets with a single 3.8% rate, so the state portion is straightforward. Federal income tax is not modeled here because it depends on your W-4.

Notes and tips

Overtime and bonuses are not modeled — enter your base hours for a clean annualized figure.
Some Iowa school districts add a surtax (a percentage of your state tax). Add it separately if it applies.
The Social Security wage base caps the 6.2% tax, so very high earners see a slightly higher net rate above the cap.
To see take-home for a different schedule, divide the annual net by your number of pay periods (26 bi-weekly, 24 semi-monthly, 12 monthly).

Worked example

A worker earns $25/hour at 40 hours/week:

Gross annual = $25 × 40 × 52 = $52,000
Iowa tax = ($52,000 − standard deduction) × 3.8%
FICA = $52,000 × 7.65% = $3,978
Net is the remainder after Iowa tax and FICA

Note: Estimate only, not tax advice. Federal income tax is not included. Verify rates with the Iowa Department of Revenue (tax.iowa.gov).
