Iowa withholds income tax at one rate, 3.8%, on every dollar of taxable wages after a standard deduction of $16,100 for a single filer ($32,200 for a joint return).
The calculator withholds from Iowa's 2025 rate schedule. At the default $75,000 salary, each extra $1,000 of pay adds $35.72 of Iowa tax a year.
Some Iowa school districts levy a surtax on state income tax that is not included here.
