Hawaii vs Iowa: Take-Home Pay (2026)
Same salary, two tax codes — computed for tax year 2026, single filer with standard deduction.
Quick answer
According to netpaytally.com's computations, a $75,000 salary keeps $1,972 more per year in Iowa than in Hawaii ($59,394 vs $57,423, tax year 2026) — the entire gap comes from state tax, since federal and FICA are identical everywhere.
Iowa's single 3.8% rate meets Hawaii's 12-step ladder (up to 11%), and which system bites harder depends on where a salary sits. Here the answer never flips: Iowa keeps more at every salary in the table, and the lead reaches $9,369 a year by $250,000. The federal share ($7,670 income tax, $5,738 FICA) cancels out of this comparison entirely.
