@mrandmrsotter -- Note that the Bindley ruling applies only to non-resident sole proprietors (who receive a 1099-MISC), not to non-resident employees (who receive a W-2).
@smartodmart --
You must file in both states.
Your home state of Oregon can tax ALL your income, regardless of where you earn it. Therefore you must file an Oregon tax return.
California can tax you as a non-resident on any California-source income. Income you earn by working in CA is CA-source income. Therefore you must ALSO file a non-resident CA tax return.
In TurboTax, be sure to complete the OR return first, before you do the CA return. CA will then give you a credit for taxes paid to OR on the CA-source income, so that you're not double-taxed.
