Iowa standard tax deductions
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 a resident of Iowa, the school district surtax is another detail to understand when it comes to state income taxes. The surtax generates revenue that goes directly to the school district the taxpayer resides in. The amount paid is based on the taxpayer’s total individual state income tax. That amount is multiplied by the district’s surtax rate to calculate the amount owed. Each district’s rate varies, but all are within 0-20%.
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.
