Out of state internship (NY and WA) for CA resident

Hi There,

We live in CA, the children go to college in CA. Last summer, two children interned out of state.

One did a summer internship in NY, was issued a W2 with NY state tax. I assume she is consider a part-year resident for NY with form IT-203 required. Does her part-year resident NY make her a part-year CA resident with form 540NR?

My other daughter did a summer intern in Washington. Her W2 shows no Washington State income nor w/h but a fraction for federal income is being reported as CA income. I believe WA has no state income tax. Do I not need to file a state return for WA then? Does the WA summer internship make her a part-year CA resident with form 540 NR?

Thank you in advance for your help.
