Hello and thank you for using Just AnswerYou will be considered as a Nonresident of California and you will need to file a nonresident return reporting all the potion of the income that you earn in CA.
Nonresidents must file a return if they have any California source income and their income from all sources is more than the filing requirement amounts for residents.
Please let me know if you need clarification.
The portion you receive for the work in CA is the amount that will be taxable to CA. If you earn total $100,000 from all work everywhere and of that $33,000 was earned because of your work in CA, then $33,000 is what is taxable to CA. Now Illinois will tax you on all of it and you can get a credit for the taxes paid to CA on your Illinois return.Nonresidents must look to total income from all work just to see if they have earned enough that they have to file a return but just the CA portion is taxable to CA.
No, as I advised you earlier, Illinois will tax you on all income because you are a resident of Illinois. Ca will tax you only on portion you earned while actually in CA. Illinois will allow you a credit for the taxes paid to CA on the CA portion.
Not at all. I would rather you understand the situation fully then have a quick interaction.
Best wishes and thank you again.
