Before you use this estimate
This model assumes a full-year resident of Idaho, ordinary employee wages and all workdays physically in Washington. Check exemption eligibility before treating a work-state amount of $0 as your own result. Withholding is a prepayment, not final tax liability. Other income, a move during the year, remote work and separate local taxes or credits can change the result.

Tax guide and official sources: live in Idaho, work in Washington
Official agency starting points: Idaho tax agency (opens in new tab) · Washington tax agency (opens in new tab). These directory links identify the selected states' agencies, not your filing obligations. Check their individual-tax guidance and forms for the year you are filing.
This is the usual filing pattern, not a determination that you must file. Filing thresholds, age or dependent status, other income and withholding refunds can change which returns you need.
How this $100,000 estimate adds up
These steps follow the selected home, work state, salary and filing status. They reconcile the model's annual liability, not the amounts withheld from your paycheck.
| Step | Washington work state | Idaho home state |
|---|---|---|
| Tax before the modeled other-state credit | $0 | $4,192 |
| Modeled other-state credit subtracted | $0 | $0 |
| Tax after that credit | $0 | $4,192 |
Total: $0 + $4,192 = $4,192 a year. Amounts are rounded for display. Work-state wage exemptions, when applicable, are already reflected in the first row; they are not an other-state credit.
No other-state credit is subtracted in this selected scenario. Included county components stay in these amounts; excluded local taxes and credits stay excluded. Federal income tax, payroll programs and refund eligibility are outside this reconciliation.

Frequently asked questions
Do I pay Washington income tax if I live in Idaho?
No. Your work state has no tax on wages, so you pay only your home state.
Do I have to file taxes in both Idaho and Washington?
Usually you file only one state return (a resident return in Idaho), though some states still require a nonresident return to get a refund of any wrongly withheld tax.
Will I be taxed twice?
No. Washington doesn't tax these wages at the state level; the modeled Idaho tax is about $4,192 on $100,000. Local taxes need a separate check.
