What to do next

How it works

The calculator starts from your income after pre-tax contributions, takes federal taxable income as the base, subtracts Iowa's standard deduction and personal exemptions where they exist, and applies a flat 3.8% state income tax. Personal credits come off the tax. Iowa allows a personal credit of $40 and federal taxable income as the starting point.

Things to keep in mind

Some cities or counties in Iowa levy their own income or wage tax, which is not included here. Itemized deductions and state-specific credits are not applied, so filers with large deductions will owe less than shown.

Some Iowa rules, such as high-income phase-outs or special rates on certain income, are left out of this estimate. The state revenue department's own calculator or instructions have the full detail.
