The Iowa Income Tax
Iowa collects a state income tax at a maximum marginal tax rate of %, spread across tax brackets. Like the Federal Income Tax, Iowa's income tax allows couples filing jointly to pay a lower overall rate on their combined income with wider tax brackets for joint filers.
Notably, Iowa has the highest maximum marginal tax bracket in the United States. You can learn more about how the Iowa income tax compares to other states' income taxes by visiting our map of income taxes by state.
All single filers with a gross income of over $9,000 per year must file an Iowa tax return, and those filing as a couple or head of household must file if they earned over $13,500. Nonresidents must file a Nonresident Income Tax Return if they earned over $1,000 of income in Iowa over the filing period. Special filing limits also exist for seniors, dependents or military servicemen.
Iowa allows some local jurisdictions, like school districts, to charge a local surtax on top of the Iowa Income Tax. You can find more details about this surtax below.
Unlike the Federal Income Tax (which is due on April 15th), Iowa taxpayers have an extra 15 days to submit their Iowa tax return, which is due on April 30th of every year. If April 30th falls on a weekend, the tax due date is pushed up to the following Monday.
If you cannot pay your whole income tax bill, you are encouraged to submit a partial payment with your income tax return. Even if you cannot pay, you must still file. If you pay less then 90% of your tax debt on the due date, you will be charged a late fee of 5% or 10% (depending on whether you submitted your tax return, with or without a payment, on time).
Iowa Earned Income Tax CreditIf you want to claim an Warned Income Tax Credit (EITC) on your Iowa tax return, you must be have received the EITC on your Federal Tax Return. As of 2010, if you have received the EITC on your federal return, you can claim 7% of your Federal credit as a refundable credit on your Iowa income tax return.
Iowa Local School SurtaxAnother tax to keep in mind when filing your Iowa tax return is the local school surtax, which is collected by over 80% of Iowa's school districts. School districts in Iowa are permitted collect a surtax of up to 20% of the state income tax you pay (not 20% of your reported income), and these rates vary by school district. The average surtax is 0.3% (weighted by income, according to Tax Foundation data), and total of 297 Iowa school districts impose an income tax surcharge.
For example, if your local school district has a 5% surtax and you paid $1,000 in state income tax you will owe an additional $50 surtax to your local school district. In addition to school districts, municipalities may also impose an additional Local Option surtax to fund emergency medical services. You can access a full list of Iowa's school districts, with their 2012 local surtaxes, here.
There are 142 days left until Tax Day, on April 16th 2025. The IRS will start accepting eFiled tax returns in January 2020 - you can start your online tax return today for free with TurboTax .
