How 1099 income is taxed in Iowa
Iowa has a flat income tax of 3.8% on all taxable income. Your net profit from freelancing is added to any other income and taxed at these rates, on top of federal self-employment tax and federal income tax.
Before the rates apply, Iowa gives a standard deduction of $16,100 for single filers ($32,200 married filing jointly).
Iowa also gives a personal tax credit of $40 ($80 for married couples), which reduces the tax directly.
On the federal side, every self-employed person pays self-employment tax of 15.3% on 92.35% of net profit (12.4% Social Security up to $184,500 and 2.9% Medicare), and federal income tax on profit after deducting half of the self-employment tax, the standard deduction and, for most freelancers, the 20% QBI deduction.

Paying estimated taxes in Iowa
Because no one withholds tax from 1099 income, you normally make quarterly estimated payments to the IRS and to Iowa. The IRS deadlines for 2026 are April 15, June 15 and September 15, 2026, and January 15, 2027. Most states use the same or very similar dates, but check Iowa's department of revenue for its exact deadlines and how to pay online.
A simple habit: move the "set aside per month" amount from the calculator into a separate savings account every time you get paid. See the federal side in more detail with our quarterly estimated tax calculator, or work out what to charge with the hourly rate calculator.
