Local context: Idaho
Housing economics in Idaho. The median home value runs 29.9% above the U.S. baseline for Idaho is $465,000 per Zillow's home-value index. Effective property tax sits at 0.69% of assessed value, below the 0.99% national average tracked by the Tax Foundation. Lenders in Idaho have quoted 6.30% on the 30-year fixed product over the trailing four-week window per Freddie Mac PMMS — the prevailing posted rate before any borrower-specific lock-ins.
Income and tax climate. Median household income in Idaho reaches $81,650 per the ACS five-year vintage, pulling above the $78,538 U.S. median. Idaho's top marginal state income tax bracket lands at 5.70% — compared to the volume-weighted national average around 4-5%. State sales tax sits at 6.00% before local add-ons; combined rates in metro areas frequently push 1-3 percentage points higher. BEA's Regional Price Parity scores Idaho at 92.2 (national = 100), meaning a dollar in Idaho buys 108¢ — more goods and services than the same dollar nationally.
How Idaho's tax structure plugs into the calculator. Federal brackets are the same in every state, but the state-level overlay changes the marginal and effective rates that actually leave your paycheck. The income tax, paycheck, capital gains, and self-employment calculators all factor Idaho's top marginal rate, standard deduction, and (where applicable) local payroll levies into the take-home math. Sales tax surfaces in cost-of-living comparisons rather than in income calculators. Property tax shows up only on real-estate calculators. Each calculator on this page uses the Idaho numbers above where the rule applies and federal-default values everywhere else.

How we compute these figures — methodology
This page combines three inputs: (1) the calculator formulas themselves, which run client-side so no inputs leave your browser; (2) Idaho financial constants from primary public datasets; and (3) national benchmarks for comparison. The Idaho data uses property tax effective rate (0.69%), median home value ($465,000), and 5.70% top marginal state income tax — all from the sources listed below.
Refresh cadence: state tax brackets are reviewed annually after legislative sessions. Property-tax rates, ZHVI home values, insurance premiums, and BEA RPP cost-of-living indices are reviewed annually against primary sources. Page-level dateModified matches the most recent data retrieval date shown above.
Known limits: statewide averages mask large intra-state variance — county-level property tax and metro-level home prices differ significantly. For precise per-city figures, click through to individual calculator pages.
