How Iowa withholds on severance
Iowa withholds a flat 3.8% on supplemental wages like severance. On top of that, the federal government withholds a flat 22% (37% over $1 million) and FICA, 6.2% Social Security up to the $184,500 wage base plus 1.45% Medicare.
Iowa taxes income at a flat 3.8%, which is the rate that applies to severance whichever way it's withheld. If you also claim unemployment, Iowa pays up to $644 a week for up to 16 weeks, and taxes it on the state return. That's the Iowa layoff picture in one place, the severance tax here, the unemployment on its own Iowa page.
Worked example: $40,000 severance in Iowa
A single filer, $40,000 severance paid separately, with $60,000 of other 2026 income:
| Federal withholding (22%) | −$8,800 |
| FICA (Social Security + Medicare) | −$3,060 |
| Iowa withholding | −$1,520 |
| Net check | $26,620 |
| What it actually costs in tax | $12,730 |
Over-withheld by about $650, expect roughly that back as a refund at filing. The withholding is a fixed rate; your actual tax is your marginal rate on the severance stacked on your other income.
