Iowa taxes wages at a flat 3.8% state rate in 2026 — the same rate whatever you earn — on top of federal income tax and FICA. Single filers get a standard deduction of $16,100. Use the calculators below to see your exact 2026 take-home pay in Iowa, check the sales tax on a purchase, and estimate a mortgage payment with Iowa property taxes factored in.

Estimate take-home pay after federal tax, FICA and your state’s income tax for the 2026 tax year.
How it works: the 2026 federal standard deduction ($16,100 single, $32,200 married filing jointly) comes off your salary first, then the 2026 federal brackets (10%–37%). FICA is applied properly: 6.2% Social Security on the first $184,500 of wages (2026 wage base), 1.45% Medicare on all wages, plus 0.9% additional Medicare on wages above $200,000 single / $250,000 married filing jointly. State tax applies each state’s own standard deduction/exemptions, then its brackets or flat rate. Local income taxes are not included — many cities and counties (e.g. New York City, Philadelphia, most of Ohio, Maryland counties, Indiana counties, Kentucky) levy their own payroll taxes on top of the state tax.

The statewide base sales tax rate in Iowa is 6% in 2026. Cities and counties can add their own local tax on top of the base rate — enter any local add-on below to see the full tax and total price.

Estimate the sales tax and total price using each state’s base rate (2026), plus any local add-on.
State base rates are the 2026 state-level rates (local add-ons excluded). Actual combined rates vary widely by city and county — many localities add 1–5%. Five states have no statewide sales tax (Alaska, Delaware, Montana, New Hampshire, Oregon), though some localities still levy local taxes.
Mortgage calculator for Iowa homes
The average effective property tax rate in Iowa is about 1.39% of a home’s value per year. When you use the mortgage calculator below, enter roughly that percentage of the home price in the yearly property tax field for a realistic Iowa monthly payment.
Mortgage Payment Calculator
Work out your monthly principal & interest payment, total interest and the true total cost of your loan.
How it works: your loan amount (price minus down payment) is repaid in equal monthly instalments using the standard amortisation formula, so early payments are mostly interest and later ones mostly principal. Property tax and insurance, if entered, are simply spread evenly across each month. Your actual rate and payment will depend on your lender, credit profile and the deal you choose.
9%. That was Iowa’s top income tax rate not long ago, spread across nine brackets. Now? One flat rate, 3.80%, and the state doesn’t even start with your salary — it starts with your federal taxable income. So the federal standard deduction does the heavy lifting before Iowa gets a look-in. But don’t celebrate too fast. Iowa gives with one hand and takes with the other, and the taking happens on your house.
Income tax in Iowa in 2026
The rate is 3.80%, flat, in effect since 2025. That’s the finish line of a multi-year phase-down that dismantled the old nine-bracket system piece by piece.
Here’s the part that trips people up. Iowa begins with federal taxable income. If you’re single, the federal standard deduction of $16,100 is already gone from the number Iowa taxes. You don’t claim a separate Iowa standard deduction. It’s baked in. Itemized on your federal return? That flows through too.
And there’s no personal exemption deduction. Instead you get a $40 credit — small, almost symbolic, but it’s a credit, so it knocks $40 straight off the bill rather than off your income. Dependents and other situations can bring extra credits. The $40 is the one nearly everyone gets.
One consequence worth knowing: two Iowans on identical salaries can owe different amounts. Pre-tax retirement contributions change federal taxable income, and Iowa follows that number wherever it goes. For most standard-deduction wage earners, though, the formula is dead simple.
Worked example: $75,000 salary, single filer
Step 1 — Taxable income. Because Iowa starts from the federal figure, you subtract the federal standard deduction of $16,100 from $75,000. State taxable income: $58,900.
Step 2 — State tax. $58,900 × 3.80% = $2,238.20. Knock off the $40 credit and you land at $2,198.20. That’s an effective rate of roughly 2.9% of gross pay.
Step 3 — Federal tax. After the same $16,100 deduction, federal income tax comes to $7,670.00.
Step 4 — FICA. Payroll taxes total $5,737.50 — $4,650.00 for Social Security plus $1,087.50 for Medicare.
Step 5 — Take-home. $75,000 − $2,198.20 − $7,670.00 − $5,737.50 = $59,394.30 per year, about $2,284.40 bi-weekly. That’s before health insurance, retirement contributions, or anything else your employer pulls out.
Sales tax in Iowa
The state rate is 6.00%. On a $1,000 purchase, that’s $60.
But you’ll rarely pay exactly that. A 1% local option tax applies in most of Iowa, so the combined rate at most checkouts is 7%. Budgeting for a fridge, a car repair, a laptop? Use 7%. The 6% figure is technically correct and practically misleading.
Property tax in Iowa
Here’s the catch. Iowa’s average effective property tax rate is 1.39% — a statewide average, and well above what most states charge. A $300,000 home carries about $4,170 per year.
Read that against the worked example above. The property tax on that house is nearly double the state income tax on a $75,000 salary. Local services lean hard on property owners here, and your real bill swings with county, city, and school district levies, plus assessments and rollbacks. Moving to Iowa for the low income tax? Fine. Just price the house tax into the decision from day one.
Frequently asked questions
When did Iowa switch to a flat tax?
2025. The single 3.80% rate completed a phase-down from nine brackets with a top rate near 9%.
So there’s no Iowa standard deduction at all?
Not a separate one, no. Iowa starts from federal taxable income, so the $16,100 federal standard deduction for a single filer in 2026 is already reflected in the number Iowa taxes.
What does the $40 credit actually do?
It cuts your final bill by $40. Not your income — your bill.
Why did I pay 7% sales tax when the state rate is 6%?
Because most Iowa localities add a 1% local option tax on top of the 6.00% state rate. Combined, most shoppers pay 7%.
Are Iowa property taxes genuinely high, or is that exaggerated?
Genuinely high. The statewide average effective rate is 1.39%, about $4,170 a year on a $300,000 home. Your mileage will vary by locality — sometimes a lot — but the average isn’t a scare story.
