What Affects Your Software Engineer Paycheck in Iowa

Federal Tax Brackets
Most mid-level engineers fall in the 22-24% federal bracket. Senior and staff engineers earning $200k+ enter the 32-35% bracket.
Iowa State Tax
Iowa taxes income at 6.0%. On a $150k salary this is $9,000/year in state taxes.
401(k) Max-Out
The 2026 limit is $23,500 ($31,000 if 50+). At the 24% bracket, maxing out saves $5,640/year in federal taxes alone.
RSU Vesting
