Commuter taxes 2026

Live in Idaho, work in Oregon

Without wage reciprocity, the work state may tax wages earned there. Your home state generally offers a limited credit for eligible tax paid on the same income. Filing requirements, credit limits and local taxes need a separate check.

Before you use this estimate

This model assumes a full-year resident of Idaho, ordinary employee wages and all workdays physically in Oregon. 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.

State income tax: $7,148 a year

Modeled annual state income tax for living in Idaho and working in Oregon: about $7,148 on $100,000 of wages, $2,956 more than if you worked in Idaho.

Limits of this estimate:

Oregon uses provisional withholding-based 2026 planning inputs; confirm the final annual-return parameters.
Idaho's zero-rate band uses the published 2025 annual-schedule fallback; confirm the final 2026 annual schedule.

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.

Modeled state income tax for Idaho residence and Oregon work
Step	Oregon work state	Idaho home state
Tax before the modeled other-state credit	$7,148	$4,192
Modeled other-state credit subtracted	$0	$4,192
Tax after that credit	$7,148	$0

Total: $7,148 + $0 = $7,148 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.

The modeled credit is applied in Idaho, the home state. Actual eligibility and credit limits require the state instructions. 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.

From paycheck withholding to your returns

Withholding: Give Oregon payroll the 2026 Form OR-W-4 for Oregon-source wages. Idaho residence alone does not exempt those wages from Oregon withholding. Review Idaho resident withholding or estimates separately; the resident credit is an annual-return calculation.
Returns: Prepare Oregon nonresident Form OR-40-N first, then Idaho resident Form 40 with Form 39R, Part C. Include Form 39R and a copy of the Oregon return with the Idaho filing. The linked annual-return instructions are the 2025 editions; use final forms for the tax year being filed.
Credit or refund: Idaho gives its resident the limited credit for eligible Oregon tax on wages taxed by both states. Claim it on Idaho Form 40 using Form 39R, not as a reverse credit on Oregon's nonresident return. The credit cannot exceed the Idaho tax attributable to the doubly taxed income; the two states' income definitions and other credits can change the limit.

Worked example: $100,000 of wages

Single filer, full-year resident of Idaho, all work performed in Oregon, no other income, standard deductions and modeled personal exemptions. Before credit, Idaho tax is $4,192. Modeled Idaho credit: $4,192. Pay $7,148 to Oregon and $0 to Idaho, modeled total $7,148.

The Oregon planning estimate before any home-state credit is $7,147.75. Idaho's pre-credit estimate is $4,191.72, so the modeled Idaho credit is $4,191.72 and Idaho state tax after it is $0; the total remains $7,147.75. Oregon uses provisional 2026 withholding-based inputs ($2,910 single deduction and $263 credit), while its estimated-return guide lists $2,900 and $260. Idaho uses the 2026 federal standard deduction and the published 2025 $4,811 zero-rate-band fallback. Confirm final 2026 annual instructions. Idaho's refundable food-tax credit, $10 Permanent Building Fund amount and other special adjustments are outside this comparison.

Annual liability, not paycheck withholding or a refund estimate. Federal tax, payroll programs, other local taxes, special credits and part-year residency are excluded. Local income taxes not included.

Remote-work and local exceptions

All wages in this example come from work physically performed in Oregon by a full-year Idaho resident. Days worked at home in Idaho are not Oregon employee services merely because the employer is based in Oregon; keep actual work-location records. Other income, changed residence and special compensation require separate allocation. Oregon local income taxes and payroll programs are excluded.

Official forms and instructions

Source audit 2026-10-20. Use the return and instructions for the year you are filing; a current-forms link may still show a prior-year return. Official sources checked; not independently reviewed.

What to do

Keep a record of the days you work in each state, especially if you sometimes work from home.

Working from home for an Oregon employer

Oregon has a "convenience of the employer" rule. Limited rule: applies only to nonresidents in managerial roles for Oregon employers. Not a general remote-worker rule.

Local income taxes

Oregon: For 2026, Metro Supportive Housing Services tax is 1% of Metro taxable income above $128,000 Single or $205,000 joint. Multnomah County Preschool for All tax is 1.5% above $125,000 Single or $200,000 joint, with an additional 1.5% above $250,000 Single or $400,000 joint. These separate local taxes can apply to district residents and nonresidents on income earned in the district; they are excluded here. Oregon's separate Statewide Transit Tax is 0.1% on Oregon residents' wages regardless of where they work and on nonresidents' wages for services performed in Oregon; this payroll tax is also excluded from the commuting state-income-tax estimate.

Frequently asked questions

Do I pay Oregon income tax if I live in Idaho?

Yes. Oregon taxes wages earned there by nonresidents. On $100,000 that's about $7,148.

Do I have to file taxes in both Idaho and Oregon?

Prepare Oregon nonresident Form OR-40-N first, then Idaho resident Form 40 with Form 39R, Part C. Include Form 39R and a copy of the Oregon return with the Idaho filing. The linked annual-return instructions are the 2025 editions; use final forms for the tax year being filed.

Will I be taxed twice?

The modeled state credit reduces overlap on eligible wages; separate local taxes or sourcing differences can still leave additional tax. Idaho credits the tax you pay Oregon, so your total is about $7,148 on $100,000, compared with $4,192 if you also worked in Idaho. Local city or county taxes may still apply.
