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 Credit

If 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 Surtax

Another 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.

Iowa State Income Tax Deductions

Income tax deductions are expenses that can be deducted from your gross pre-tax income before determining your taxable income.

Iowa Standard Deduction

The Iowa standard deduction is $1,900.00 for individuals and $4,670.00 for married couples filing jointly. The standard deduction may be chosen instead of filing an itemized deduction on your Iowa tax return.

Iowa Personal Exemptions

Iowa's personal income tax exemptions include a personal exemption of $40.00. You can deduct one single exemption from your gross income if you are responsible for supporting yourself financially.

Iowa Dependent Deduction

Iowa has a dependent exemption of $40.00. You may claim one dependent exemption for each of the children, relatives, or others who live with and are supported by you as described § 152 of the IRC (Internal Revenue Code).

Iowa Itemized Deductions

Iowa allows itemized deductions, and you can claim the same itemized deductions on your Iowa tax return as you do on your Federal tax return. You must choose between itemizing your deductions and choosing the Iowa standard deduction, so it's generally only worth itemizing your deductions if your itemized total is more then the Iowa and Federal standard deductions.
