A $10,000 crypto gain realized in Iowa attracts about $380 in Iowa tax — a marginal rate of 3.80% — for someone otherwise earning the state median of $85,480. Federal capital-gains tax applies on top.

Iowa taxes capital gains as ordinary income, so the gain stacks on your other income and is taxed at the rate that band falls in. Figures use 2026 Iowa rules and 2026 federal rules, single filer. Holding period decides the federal rate.

Crypto capital-gains tax in Iowa

Iowa moved to a flat 3.8% individual income tax starting tax year 2025, down from a 5.7% top rate in 2024. Iowa taxable income starts from federal taxable income, so the federal standard deduction is effectively built in (approximated here). Retirement income is fully excluded for taxpayers 55 and older, and many localities levy school-district surtaxes not included in this estimate.

Iowa taxes capital gains and crypto as ordinary income, so they face the same flat 3.8% rate as wages.

Common questions

How are crypto gains taxed in Iowa?
Iowa has one rate for everything, so this estimate adds crypto gains to your other income and taxes them at the flat 3.8% that applies to wages for 2026, after a $16,100 standard deduction ($32,200 joint). Any Iowa subtraction or exclusion for long-term gains is not applied here.
How much Iowa tax would a $10,000 crypto gain cost?
About $380. That is the 3.8% flat rate applied to the gain once it is stacked on Iowa's $85,480 median household income (2024), and it is on top of federal capital-gains tax.
Does a bigger gain face a higher Iowa rate?
No — Iowa's rate is flat, so this estimate applies 3.8% to the gain whatever its size: $380 on a $10,000 gain and $3,800 on a $100,000 one. Only your federal rate changes as the gain grows.

Crypto tax rules are complex and Iowa state treatment is simplified here — verify with the state Department of Revenue and a tax professional. Iowa's flat 3.8% is applied with the $16,100 standard deduction for a single filer — not itemized deductions or any Iowa tax credit. It also excludes any local, county, or school-district tax your municipality may add.
