- The flat rate is scheduled to decline further in coming years.

Federal income tax withholding (2026)
Federal income tax withholding is calculated using the annualization method from IRS Publication 15-T. Your per-period gross pay is annualized, reduced by the standard deduction ($16,100 single / $32,200 married / $24,150 head of household in 2026), and then taxed at the applicable bracket rates. The resulting annual tax is divided by your number of pay periods.
2026 federal tax brackets
| Taxable Income (Single) | Rate |
|---|---|
| $0 – $12,400 | 10% |
| $12,400 – $50,400 | 12% |
| $50,400 – $105,700 | 22% |
| $105,700 – $201,775 | 24% |
| $201,775 – $256,225 | 32% |
| $256,225 – $640,600 | 35% |
| Over $640,600 | 37% |
FICA: Social Security & Medicare
FICA taxes are the same in every state. Social Security is withheld at 6.2% on wages up to $184,500 (2026 wage base). Once your wages reach that cap in a calendar year, Social Security withholding stops. Medicare is withheld at 1.45% with no wage cap. An additional 0.9% applies to wages above $200,000 (single) or $250,000 (married).
Pre-tax deductions and your paycheck
Traditional 401(k) contributions and employer-sponsored health insurance premiums (Section 125/cafeteria plan) reduce your federal and state taxable income, lowering your income tax withholding. However, 401(k) contributions do not reduce FICA (Social Security and Medicare) wages. Health insurance premiums under a Section 125 plan do reduce FICA wages. Use the "Show deductions" section above to model your specific situation.
Frequently asked questions
- A single filer earning $65,000 in Iowa takes home approximately $52,492 per year in 2026 — about $4,374 per month, or $2,018.93 per biweekly paycheck. That reflects $5,620 in federal income tax, $4,973 in FICA (Social Security and Medicare), and $1,915 in Iowa state income tax. Pre-tax deductions like a 401(k) or health insurance would change these numbers.
- Iowa has a flat state income tax rate of 3.8%. After the state's deductions, a single filer pays about $1,345 on a $50,000 salary, $2,295 on $75,000, and $3,245 on $100,000. Use the calculator above to see your exact per-paycheck withholding.
- Iowa does not have a statewide local income tax layer. Your paycheck deductions consist of federal income tax, Social Security, Medicare, and Iowa state income tax — no additional local income taxes are withheld at the state level.
- Start with your gross pay per paycheck. Subtract: (1) federal income tax based on your filing status and 2026 brackets; (2) Social Security at 6.2% up to the $184,500 wage base; (3) Medicare at 1.45%; (4) Iowa state income tax. Any pre-tax deductions like 401(k) or health insurance reduce your taxable income further. The calculator above does this math instantly.
- Iowa's 3.8% flat income tax applies to wages and salaries. Whether Iowa taxes Social Security retirement benefits depends on your specific situation — check the Iowa Department of Revenue for current exemption rules. Paycheck withholding (what this calculator estimates) applies only to wages, not retirement benefits.
- Iowa does not require additional state payroll contributions beyond state income tax withholding. Some states (notably California, New Jersey, and New York) require workers to contribute to state disability insurance (SDI) or paid family leave (PFL) programs — Iowa is not one of them.
