Iowa standard tax deduction
Iowa no longer has its own standard deductions and will instead follow the federal standard deduction. Taxpayers must use the same filing status on their Iowa tax return that they used on the federal tax return. Married taxpayers also can no longer file separately on a combined return.

Iowa School District Surtax
As an Iowa resident, it’s important to understand the school district surtax when dealing with state income taxes. This surtax generates revenue that directly benefits the school district where the taxpayer resides. The amount owed is based on the taxpayer’s total state income tax, which is then multiplied by the surtax rate specific to their district. Each district has a different rate, but all rates fall within the range of 0% to 20%.
Example: If a taxpayer’s total state income taxes are $1,000, and they live in a school district with a 10% surtax, the school district surtax is $100.
