Before you use this estimate
This model assumes a full-year resident of Oregon, ordinary employee wages and all workdays physically in California. 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.
Which state gives the credit: Not wage reciprocity: reverse-credit arrangement. Eligible Oregon residents report the income on their home-state return, then claim the limited credit for Oregon state income tax on the California nonresident return. Prepare the home-state return first. Do not claim the same credit in both states.

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 | California work state | Oregon home state |
|---|---|---|
| Tax before the modeled other-state credit | $4,911 | $7,148 |
| Modeled other-state credit subtracted | $4,911 | $0 |
| Tax after that credit | $0 | $7,148 |
Total: $0 + $7,148 = $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 California, the work state. Do not subtract it again in Oregon. 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 CA | To OR | Modeled total | If you worked in OR |
|---|---|---|---|---|
| $50,000 | $0 | $3,204 | $3,204 | $3,204 |
| $75,000 | $0 | $5,055 | $5,055 | $5,055 |
| $100,000 | $0 | $7,148 | $7,148 | $7,148 |
| $150,000 | $0 | $12,805 | $12,805 | $12,805 |
| $250,000 | $0 | $22,705 | $22,705 | $22,705 |
Single filer, all wages earned in California, 2026 state tax rules, standard deductions. Local income taxes not included.
From paycheck withholding to your returns
- Withholding: California payroll may withhold on California-source wages. Check Oregon resident withholding or estimates separately; the California credit is an annual-return calculation, not an automatic payroll exemption.
- Returns: Prepare Oregon resident Form OR-40 first, then California Form 540NR with Schedule S. California's credit claim requires the supporting Oregon return and follows Schedule S's limits.
- Credit or refund: For eligible Oregon-resident ordinary wages, California gives the limited credit for Oregon tax on income taxed by both states. Claim it on the California nonresident return, not a second credit on Oregon's resident return; county or city tax is not eligible for California's credit.
Worked example: $100,000 of wages
Single filer, full-year resident of Oregon, all work performed in California, no other income, standard deductions and modeled personal exemptions. Before credit, California tax is $4,911. Modeled California credit: $4,911. Pay $0 to California and $7,148 to Oregon, modeled total $7,148.
Oregon uses provisional 2026 withholding-based inputs, including the $2,910 single deduction and $263 personal credit; confirm final annual-return instructions. California uses the published 2026 indexed inputs. Neither amount includes every special credit, local tax or return-level adjustment.
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 here are earned physically in California by a full-year Oregon resident. Oregon home-working days are not California employee services merely because the employer is based there. Hybrid allocation, changed residence and other income need separate checking; local taxes are excluded.

What to do
- Keep a record of the days you work in each state, especially if you sometimes work from home.
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.
Special credit rules
- CA: Not wage reciprocity: reverse-credit arrangement. Eligible Oregon residents report the income on their home-state return, then claim the limited credit for Oregon state income tax on the California nonresident return. Prepare the home-state return first. Do not claim the same credit in both states.
Frequently asked questions
Do I pay California income tax if I live in Oregon?
California taxes eligible wages earned there before credit. In this $100,000 example its tax before credit is about $4,911, and its modeled tax after the eligible credit for Oregon state tax is $0. Prepare the Oregon return first; credit limits, other income and local taxes need a separate check.
Do I have to file taxes in both Oregon and California?
Prepare Oregon resident Form OR-40 first, then California Form 540NR with Schedule S. California's credit claim requires the supporting Oregon return and follows Schedule S's limits.
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. California credits the tax you pay Oregon, so your total is about $7,148 on $100,000, compared with $7,148 if you also worked in Oregon. Local city or county taxes may still apply.
