Idaho Financial Snapshot (2026) — Capital Gains Tax Calculator
Bracket stack and standard deduction are the primary inputs for the capital gains tax calculator in Idaho. Every row cites a primary public dataset. Numbers reflect the most recent vintage available; refresh cadence is documented in the methodology.
How the Capital Gains Tax Calculator Math Works Under Idaho Law
Your Idaho capital gains tax calculator stacks federal and state income tax onto FICA (Social Security 6.2% + Medicare 1.45%). Idaho's 2026 structure is graduated, with a top marginal rate of 5.70%[1]. Standard deduction for single filers: $15,000. Married filing jointly: $30,000.
| Taxable income (single) | Marginal rate |
|---|---|
| $0 – $4,673 | 0.00% |
| $4,673+ | 5.70% |
Calc-specific note: Federal LT rate (0/15/20%) stacks on top of Idaho's ordinary-income rate — there's no separate state capital gains bracket.
Worked example — Idaho
A Idaho investor realising $69,750 in long-term capital gains (15% on a $465,000 position) pays 15% federal ($10,463) plus 5.70% state ($3,972) = $14,435 combined. The 3.8% NIIT may apply above $200k MAGI.

Sales tax surfaces in cost-of-living comparisons rather than in income calculators. Property tax shows up only on real-estate calculators.
