  • About This Answer

    Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions. Also, we separately calculate the federal income taxes you will owe in the 2020 - 2021 filing season based on the Trump Tax Plan.

    How Income Taxes Are Calculated

    • First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
    • Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer as well as dependents such as one’s spouse or children.
    • Based on your filing status, your taxable income is then applied to the the tax brackets to calculate your federal income taxes owed for the year.
    • Your location will determine whether you owe local and / or state taxes.

Taxes in Iowa

Iowa State Tax Quick Facts

  • Income tax: 0.33% - 8.53%
  • Sales tax: 6% - 7%
  • Property tax: 1.53% average effective rates
  • Gas tax: 30 cents per gallon of regular gasoline, 32.5 cents per gallon of diesel

Earlier this decade, Iowa enacted one of the largest tax cuts in the state’s history. While that cut was largely focused on commercial property owners, it also lowered residential property taxes across the state. Even so, with an effective property tax rate of 1.53%, Iowa’s property taxes are the 11th-highest in the country.

The state’s income tax system features one of the highest top rates, which at 8.53% ranks among the highest states. But it also has one of the lowest bottom rates. Earners in Iowa’s bottom tax bracket pay a rate of just 0.33%. The sales tax in Iowa, meanwhile, ranges from 6% to 7% when including local rates, which is near the national average.

A financial advisor in Iowa can help you understand how these taxes fit into your overall financial goals. Financial advisors can also help with investing and financial plans, including retirement, homeownership, insurance and more, to make sure you are preparing for the future.

Iowa Income Taxes

The Hawkeye State’s income tax system has nine income brackets, with marginal rates between 0.33% and 8.53%.

$33,520 - $50,2806.25%
$50,280 - $75,4207.44%
$75,420+8.53%

These rates are assessed on Iowa taxable income, which is income after all deductions have been subtracted. In Iowa, you may claim itemized deductions even if you claimed the standard deduction on your federal return. However, you can instead choose to claim the Iowa standard deduction: $2,130 for single filers and married persons who are filing separately, and $5,240 for married persons filing jointly and heads of household.

After determining their Iowa state tax liability, many Iowa taxpayers must pay a school district surtax. This is equal to a percentage of Iowa taxes paid, with rates ranging from 0% to 20%. So, for example, if your Iowa tax liability is $1,000, and your school district surtax is 15%, you would pay an additional $150. The table below shows the school district surtaxes for all Iowa school districts that collect a surtax.

Iowa Tax Credits

Iowa offers several types of tax credits to state taxpayers. The Earned Income Tax Credit is available to Iowa residents who have an income below a threshold that varies depending on your number of dependents. The credit is worth 15% of the amount of your federal credit.

The Child and Dependent Care Credit is equal to up to 75% of the federal credit. The percentage diminishes with higher levels of income and is zero for taxpayers with income of $45,000 or higher. Taxpayers who do not claim that credit may claim the Early Childhood Development Credit, which is equal to 25% of the first $1,000 of certain expenses paid for children ages three though five.

The Tuition and Textbook Credit is available to taxpayers with a dependent who is in school, from kindergarten through grade 12. The credit is 25% of the first $1,000 paid for tuition and books.

Iowa Sales Tax

The base sales tax rate in Iowa is 6%, but many counties collect an additional “local optional” tax of 1%, meaning the actual rate collected in most places is 7%. A few counties do not collect that additional tax on a county-wide basis, but some cities within those counties do.

Iowa taxes all tangible personal property (with a few exceptions) as well as most services. Some examples of the types of services that are taxed in Iowa are haircuts, television subscriptions, dating services, exterminators, dry cleaning, shoe repair, Turkish baths and vehicle repair.

The most significant exception to the sales tax in Iowa is food. Most items you can find in a grocery store or market are not taxable. For example, bread, fish, frozen foods, fruit, tea and butter are all exempt. Food prepared for immediate consumption and candy are all taxable, however. Prescription drugs and many non-prescription medications are also tax-exempt. No tax is collected on insulin, nebulizers, oxygen or diabetic testing devices.

Clothing is also exempt during Iowa’s annual sales tax holiday. During the first Friday and Saturday in August, clothing and footwear costing less than $100 can be purchased sales tax-free.

Iowa Property Tax

Property taxes in Iowa are based on a variety of factors. State and local governments calculate the overall rate for residential homes in a certain tax district based on the total value of homes in that area and the total amount of revenue the tax needs to generate. That rate is then applied to the assessed value of each home. This means that rates can go up or down from year to year, even if your own home’s value does not change.

The average property tax paid in Iowa is around $2,430 a year. That is slightly lower than the national average, but because Iowa home values are also lower than the national average, the average effective property tax rate (annual taxes as a percentage of home values) ranks much higher. The average effective property tax rate in Iowa is 1.53%, higher than all but 10 other states.

If you’re thinking about buying a home in the Hawkeye State or looking into refinancing a property, our Iowa mortgage guide lays out the most important information about mortgage rates, the different kinds of loans and details about each county.

Iowa Inheritance Tax

While there is no estate tax in Iowa, inheritances left to certain beneficiaries may be taxed. If the decedent’s estate has a net value below $25,000, there is no tax. Likewise, surviving spouses, lineal descendants (children, step-children, grandchildren, great-grandchildren), lineal ascendants (parents, step-parents, grandparents, great-grandparents) are all exempt from the tax.

Other beneficiaries pay rates that vary depending on their relation to the deceased. Brothers and sisters pay between 5% and 10%, with any inheritance over $150,000 facing the top rate. Nieces, nephews, aunts, uncles and all unrelated beneficiaries pay between 10% and 15%, with all inheritances over $100,000 facing the top rate.

Starting with the 2021 tax year, Iowa is repealing its state inheritance tax. This is scheduled to happen on Jan. 1, 2025, with rates gradually decreasing over time.

Iowa Gasoline Tax

The gas tax in Iowa is 30 cents per gallon of regular fuel and 32.5 cents per gallon of diesel. These are both a bit above national averages.

Iowa Cigarette Tax

Iowa has a cigarette tax of $1.36 per pack.

Iowa Capital Gains Tax

Both long- and short-term capital gains are taxed at the full Iowa income tax rates, depending on your income tax bracket.

Iowa Alcohol Tax

Excise taxes on alcohol in Iowa vary depending on the type of alcohol being sold. Liquor faces a rate of $12.49 per gallon, while the tax on beer is much lower at 19 cents per gallon.

  • The Iowa state flag is similar to the French flag. This is because the state was originally a part of French Louisiana.
  • Agricultural crops cover 60% of Iowa’s land area.
  • Every four years the Iowa Caucuses receive significant national attention because they are the first event in the process to select presidential candidates.
