Quick answer
According to netpaytally.com's computations, a $75,000 salary keeps $669 more per year in Iowa than in Idaho ($59,394 vs $58,726, tax year 2026) — the entire gap comes from state tax, since federal and FICA are identical everywhere.
Both states run single-rate systems, so this entire comparison collapses to 5.3% (Idaho) against 3.8% (Iowa). No bracket climbs, no surprises at higher pay: the distance stays close to $150 per $10,000 of salary all the way up the table, and $669 a year at $75,000. The federal share ($7,670 income tax, $5,738 FICA) cancels out of this comparison entirely.
