- What is the effective tax rate on $40,000 in Iowa?
- The combined effective rate is 16.9%. That's the share of gross pay lost to federal, state, Social Security and Medicare. Marginal rate is higher because federal brackets are progressive — only the top slice of income is taxed at the highest bracket.
- Why does take-home in Iowa look moderate compared to neighbors?
- Iowa's top state rate is 3.80%. Federal tax is identical in every state — the gap between states on this page is entirely state income tax. Eight states have no income tax (AK, FL, NV, SD, TN, TX, WA, WY); the rest range from ~3% to ~13.3%.
- Does this estimate include 401(k), health insurance or local taxes?
- No. This is a top-line federal + state + FICA estimate for a single W-2 filer taking the standard deduction. 401(k) pre-tax contributions, employer health premiums, HSA, and city or county income taxes (e.g., NYC, Philadelphia) reduce take-home further. For an exact paycheck, use a payroll service or a CPA.
