This Iowa paycheck calculator 2026 shows your IA take-home pay under Iowa's new flat 3.8% income tax, plus 2026 federal income tax and FICA. A single filer earning $70,000 in Iowa takes home about $56,027 a year — roughly $2,155 per biweekly paycheck. Enter your gross pay below and this Iowa net pay calculator breaks down your 2026 paycheck for hourly or salary workers.
Your real Iowa paycheck is gross pay minus four things: Iowa state income tax, federal income tax, Social Security and Medicare (FICA), and any pre-tax deductions or local taxes. This tool calculates all of them with the verified 2026 numbers so you can see exactly where your money goes and plan a budget around your actual take-home rather than your headline salary.
This Iowa paycheck calculator annualizes your pay, applies Iowa's flat 3.8% to determine your state tax, then layers on the 2026 federal income tax and the 7.65% FICA tax, dividing the result back to your chosen pay frequency. Switch between salary and hourly, pick your pay frequency and filing status, and the breakdown updates instantly.
| Deduction | Basis (2026) | On $70,000 salary |
|---|---|---|
| IA state income tax | flat 3.8% | $2,048 |
| Federal income tax (single) | 2026 brackets | $6,570 |
| FICA | 7.65% | $5,355 |
| Net take-home | $56,027 |
A single Iowa resident earning $70,000 keeps about $56,027 a year, or roughly $2,155 per biweekly paycheck — an effective tax rate near 20.0%.
The table below shows Iowa's 2026 income tax rates as they apply to your taxable income. Select your filing status in the calculator and it applies the correct schedule automatically.
| Taxable income / item | Rate (2026) |
|---|---|
| All taxable income (2026) | 3.80% flat |
| Phased down from 2023 | 6.00%+ graduated |
| Retirement income (55+) | Exempt |
Iowa now conforms to the federal standard deduction ($16,100 single / $32,200 married for 2026) as part of its move to a flat tax, so the calculator subtracts the federal standard deduction before applying Iowa's 3.8% rate. Iowa also fully exempts retirement income for taxpayers 55 and older.
Pre-tax payroll deductions reduce your Iowa taxable wages just as they reduce federal taxable wages: traditional 401(k), 403(b), and 457 contributions, HSA and FSA contributions, and employer health premiums all come out before the flat 3.8% Iowa tax applies. Iowa retirees 55 and older get an additional break - their retirement-plan distributions are fully exempt from Iowa tax.
Hourly workers can switch the pay type to "Hourly" and enter their rate and weekly hours. The calculator annualizes (rate × hours × 52), applies the Iowa state tax plus federal tax and FICA, then divides back to your pay frequency. A $25/hour full-time worker ($52,000/year) nets roughly ~$42,598 a year in Iowa after all taxes, or about ~$1,638 per biweekly paycheck. Part-time and variable-hours workers can lower the hours-per-week field to see how a shorter schedule changes both gross and net pay; the effective tax rate falls as income drops because less of your pay reaches the higher federal and state brackets.
Federal income tax uses the 2026 brackets and the $16,100 single / $32,200 joint standard deduction. FICA is the standard 7.65% — 6.2% Social Security up to the $184,500 wage base, plus 1.45% Medicare with no cap (and 0.9% additional Medicare on wages over $200,000). These apply identically in every state; Iowa's tax is the state-specific line that sets your take-home apart.
The table below shows approximate Iowa take-home pay for common salaries, for a single filer in 2026. Use it as a quick reference, then run your exact numbers in the calculator above for a precise figure that accounts for your filing status and pay frequency.
| Annual salary | Approx. IA net (single) | Per biweekly check |
|---|---|---|
| $50,000 | ~$41,067 | ~$1,580 |
| $70,000 | ~$56,027 | ~$2,155 |
| $90,000 | ~$69,337 | ~$2,667 |
| $120,000 | ~$89,302 | ~$3,435 |
Figures assume single filer status, the 2026 federal brackets, and standard FICA. Your actual paycheck may vary with pre-tax deductions, additional withholding, dependents, and any local taxes. Notice how the effective tax rate rises with income: a higher salary pushes more of your earnings into the 22% and 24% federal brackets and, where applicable, into Iowa's upper rates, so each additional dollar is taxed more heavily than the first.
Two fully worked 2026 examples for a single Iowa filer, one salaried at $70,000 and one hourly at $25/hour (40 hours a week, about $52,000 a year). Each line shows how gross pay is reduced by the Iowa state income tax, the 2026 federal income tax, and FICA to arrive at net take-home:
| Item | Salary ($70,000/yr) | Hourly ($25/hr, 40 hrs) |
|---|---|---|
| Annualized gross | $70,000 | $52,000 |
| State income tax | $2,048 | $1,364 |
| Federal income tax | $6,570 | $4,060 |
| FICA (7.65%) | $5,355 | $3,978 |
| Net per year | $56,027 | $42,598 |
| Net per biweekly check | $2,155 | $1,638 |
The salaried worker keeps more in absolute dollars, but the hourly worker keeps a slightly higher percentage of pay because a smaller income reaches into the higher federal brackets. This is why two people in Iowa with different incomes can have meaningfully different effective tax rates even under the same state rules.
Iowa withholds supplemental wages such as bonuses at a flat 3.8% state rate for 2026, matching the flat income tax, plus the 22% federal supplemental rate and 7.65% FICA. Overtime is taxed as ordinary income at 3.8%. Iowa's flat structure makes bonus withholding simple and predictable compared with the old graduated system.
Withholding on a bonus is not your final tax. If too much is withheld, the excess comes back as a larger refund (or a smaller balance due) when you file your Iowa and federal returns. If you receive a large bonus, you can use this calculator to estimate your full-year Iowa take-home by adding the bonus to your annual gross.
Iowa has no broad local income tax, but many Iowa school districts levy a small surtax calculated as a percentage of your state income tax (often 0%-20% of the state tax, varying by district). This is modest - typically a few dollars per paycheck - and the calculator focuses on the 3.8% state tax and federal tax. Check your district's surtax rate for an exact figure.
Iowa completed a dramatic income-tax overhaul: under Senate File 2442 (2024), Iowa moved to a single flat 3.8% rate in 2025, down from a graduated system that once topped 8.98%. Iowa also exempts all retirement income (pensions, IRAs, 401(k) distributions) for residents age 55 and older, making it attractive to retirees. For workers, the flat 3.8% rate on income above the federal standard deduction keeps Iowa's effective burden low - a single $70,000 earner keeps about $56,027.
| State | State income tax on $70,000 | Approx. net (single) |
|---|---|---|
| South Dakota (no income tax) | $0 | ~$58,075 |
| Iowa (3.8% flat) | ~$2,048 | ~$56,027 |
| Illinois (4.95% flat) | ~$2,800 | ~$55,300 |
| Missouri (4.70% flat) | ~$2,345 | ~$55,730 |
The comparison above shows how Iowa's 2026 income tax stacks up against nearby states on a $70,000 single salary. No-income-tax states leave the most in each paycheck, while Iowa sits where its rate structure places it among neighbors.
Iowa uses Form IA W-4 (Employee Withholding Allowance Certificate) to set your state withholding alongside the federal W-4. Claiming allowances reduces the tax withheld each pay period, while requesting extra withholding raises it. Accurate elections matter so you neither over-withhold (an interest-free loan to the state) nor under-withhold (risking a balance due). The calculator uses standard assumptions; your actual withholding depends on your form elections.
Self-employed Iowa residents owe the same flat 3.8% state income tax on net business income, plus federal self-employment tax (15.3%) and federal income tax. Because no employer withholds, you generally pay through quarterly estimates. This calculator is built for W-2 employees; self-employed filers should also budget for quarterly payments to avoid penalties.
For the most accurate result, enter figures straight from your own documents. Pull your gross pay and pay frequency from a recent pay stub, your filing status from your latest tax return, and any pre-tax deductions (retirement, health, HSA) from your benefits enrollment. Small differences — especially filing status and pre-tax contributions — can change your take-home by hundreds or thousands of dollars a year. The calculator uses verified 2026 federal brackets, the $184,500 Social Security wage base, and Iowa's current rules, so matching the inputs to your situation gives a reliable estimate you can plan around.
A few practical tips for Iowa workers: if your pay varies, run the calculator at both your typical and your highest pay period to see the range; if you are weighing a raise or a job offer, compare net (not gross) figures, because the after-tax gain is what actually reaches your bank account; and if you contribute to a 401(k) or HSA, remember those reduce the income the calculator taxes, so your real take-home on the same salary will be higher than a no-deductions estimate. Reviewing your withholding once or twice a year keeps your refund or balance due close to zero.
Why 2026 figures matter: tax brackets, standard deductions, and the Social Security wage base change yearly, and several states (including Iowa) adjusted rates for 2026. Using a calculator built on the correct 2026 numbers — rather than a prior-year tool — matters because the differences compound across a full year of pay. This page reflects the 2026 federal standard deductions ($16,100 single / $32,200 joint), the 2026 bracket thresholds, the $184,500 Social Security wage base, and Iowa's latest published rates, so the estimate stays current for the 2026 tax year.
About $56,027 a year for a single filer in 2026, or roughly $2,155 per biweekly paycheck. That reflects about $6,570 federal tax, $5,355 FICA, and about $2,048 Iowa state income tax, for an effective rate near 20.0%.
Iowa uses a flat 3.8% for 2026. Iowa charges a flat 3.8% rate for 2026 (down from a graduated system topping 8.98%), applied after the federal standard deduction. Retirement income for residents 55+ is exempt.

Federal tax does not depend on your state. On $70,000 a single filer owes about $6,570 in 2026 federal income tax after the $16,100 standard deduction, plus $5,355 FICA. Only the Iowa state income tax is Iowa-specific.
It uses the verified 2026 federal tax brackets, the $16,100 single / $32,200 joint federal standard deduction, the $184,500 Social Security wage base, and Iowa's current state tax rules. It is an estimate for planning, not tax advice - your real paycheck depends on pre-tax deductions, withholding elections, and local taxes.
