California Non-Resident Return Required for Washington S-corp with CA source income?

[landers-megan]

Had an individual come to me who is a resident of Alaska and an owner in a Washington S-corp.  The S-corp has income apportioned to California due to services performed in California and an employee in California and received a CA K-1.  I'm not familiar with California, but individual came to me for consult because his tax preparer told him he had to file as a California non-resident for the  CA pass-through share of items and individual's stance is that is not the case.  I've poured through FTB materials and am not confident enough to answer.  Anyone willing to lend advice?

If the S Corp K-1 has CA source income, I see no reason why your client should not file a CA nonresident return.
