State tax filing

That is good to know.  Thank you.  My scenario is a bit different.  The employee lives in WA state and works part time in California and pt in WA.  I have a couple of questions.  Is this employees wages subject to CA personal income tax?  Also, how can I process multistate payroll using QuickBooks online?  I do not think it is possible to process one payperiod with two work locations.  Thanks.
