My son lived and worked in Oregon for the full year. Part way through the year he went to work for a new company that was based in CA and was not set up to handle Oregon income tax withholding. It took quite awhile for them to get this set up and as a result his W-2 shows $18K of CA income and $500 withholding as well as Oregon income and withholding. The company is not able to issue a W-2 showing any other amounts.
Since he was neither a CA resident or employed in CA, he shouldn't technically owe any CA income taxes. What is the best way to handle this? I haven't finished his federal taxes yet to have an idea what would happen if I just use the 540NR form and apportion it the way the W-2 shows it.
I'm using TurboTax and think I may have clicked some box that asked if he had earned any income in another state and checked the NO box. The program is using total federal income to calculate OR taxes even though I filled in both OR and CA income and withholding shown on his W-2. This is technically correct.
There doesn't seem to be a way on a 540NR to made the adjustment on income and my experience with CA is that they really don't want to give up anything.
Any help unraveling this would be appreciated.
