How Idaho taxes your paycheck
Idaho taxes wages at a single flat rate of 5.3%, so every dollar of taxable income is taxed the same way no matter how much you earn. Before the rates apply, Idaho allows a standard deduction of $16,100 for single filers and $32,200 for married couples filing jointly.
The rate applies only to taxable income above $4,811 for single filers ($9,622 for joint filers).
On a $75,000 salary, a single filer owes about $2,867 in Idaho income tax for 2026, an effective state rate of 3.82%.
| Rate | Single: taxable income | Married filing jointly: taxable income |
|---|---|---|
| 5.3% | over $4,811 | over $9,622 |

How Idaho compares with neighboring states
On a $75,000 salary, Idaho's income tax is the 33rd-lowest of the 50 states and DC (1st = lowest), counting the 9 states that don't tax wages at all.
Among neighboring states, Nevada takes the least state income tax on $75,000 ($0) and Oregon the most ($5,733).
What this estimate leaves out
State disability insurance and paid family-leave contributions and local income taxes are not included, and the federal figures assume the standard deduction with no credits such as the Child Tax Credit. Head-of-household and married-filing-separately returns use the state's single schedule, which a few states set separately.
