Live in Wyoming, work in Idaho
Your home state has no income tax, so there is no credit to offset the work state's tax. You pay the work state as a nonresident.

Before you use this estimate
This model assumes a full-year resident of Wyoming, ordinary employee wages and all workdays physically in Idaho. 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.

Official agency starting points: Wyoming tax agency (opens in new tab) · Idaho 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 | Idaho work state | Wyoming home state |
|---|---|---|
| Tax before the modeled other-state credit | $4,192 | $0 |
| Modeled other-state credit subtracted | $0 | $0 |
| Tax after that credit | $4,192 | $0 |
Total: $4,192 + $0 = $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.
State tax at different salaries
| Wages | To ID | To WY | Modeled total | If you worked in WY |

What to do

- Keep a record of the days you work in each state, especially if you sometimes work from home.
Frequently asked questions
Do I pay Idaho income tax if I live in Wyoming?
Yes. Idaho taxes wages earned there by nonresidents. On $100,000 that's about $4,192.
Do I have to file taxes in both Wyoming and Idaho?
Usually you file only one state return (a nonresident 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. Wyoming has no income tax, so there is no resident state income tax on these wages; you pay Idaho's nonresident tax, about $4,192 on $100,000. Local taxes need a separate check.
