Home affordability in Idaho
Using the 28% rule (housing costs ≤ 28% of gross pay) at a 6.75% 30-year fixed mortgage, reserving 25% of the housing budget for taxes + insurance + HOA, your max affordable home price is about $269,813.

Common questions
- How much of a $100,000 salary do I keep in Idaho?
- About $73,696 after federal income tax, Idaho state tax (5.93%, flat), Social Security and Medicare. That works out to roughly $6,141 per month or $2,834 every two weeks for a single filer in 2025.
- What is the effective tax rate on $100,000 in Idaho?
- The combined effective rate is 26.3%. 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 Idaho look moderate compared to neighbors?
- Idaho's top state rate is 5.93%. 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.
