Iowa has been in the middle of a dramatic tax overhaul. A 2022 law set the state on a path to a flat 3.90% income tax by 2026, down from a top rate of 8.53% just a few years earlier. The reform also phases out taxation of retirement income and eliminates the state’s inheritance tax. Combined with moderate property and sales taxes, Iowa’s tax competitiveness is improving rapidly, particularly for retirees and higher earners.

Iowa Income Tax Rates (2026)

Iowa is transitioning to a flat income tax:

Tax Rate	Taxable Income Range
3.90%	All taxable income (flat rate)

The transition schedule: 2023 — four brackets, top rate 6.00%; 2024 — 5.70% flat; 2025 — 4.40% flat (projected); 2026 — 3.90% flat. Actual implementation depends on revenue triggers being met.

Iowa’s standard deduction is ~$2,210 for single filers and ~$5,450 for married filing jointly — considerably lower than the federal amounts. Iowa also allows a personal exemption credit of ~$40 per person.

Federal tax deduction: Iowa previously allowed a deduction for federal income taxes paid, but this was eliminated as part of the 2022 tax reform, effective 2023.

Sales Tax

Component	Rate
State base rate	6.00%
Local option	0%–1%
Average combined rate	~6.94%

Most Iowa jurisdictions impose the 1% local option sales tax, making the typical combined rate 7.00%.

Exempt from sales tax: Most unprepared food (groceries), prescription medications, and medical devices. Iowa exempts most clothing from sales tax (no special reduced rate needed — clothing is simply not taxed).

Property Tax

Metric	Amount
Average effective rate	~1.43%
National average	0.99%
Rank	Among the 10 highest nationally

Iowa property taxes are significantly above the national average. Residential property is assessed at 100% of market value, though a rollback factor reduces the taxable value to approximately ~46%–54% of assessed value for residential properties.

Homestead credit: A credit applied to the property taxes on the first ~$4,850 of homestead value. The credit amount is set annually by the state.

Military exemption: An exemption of ~$1,852 of assessed value for qualifying veterans.

Example: A home with a market value of $250,000, rolled back to ~$130,000 taxable value, at a typical levy rate of ~$27 per $1,000, pays approximately ~$3,510 per year.
