State taxes on out-of-state short-term contract
Hi,
Here's my situation.
Facts:
I am a consultant for company X (W-2 arrangement),which is based in New Jersey, where I was hired for a 6-month contract in New Jersey to perform work for one of their clients--company Z. I am a current resident of Arizona where I have a house and I plan on returning after the contract and getting work back in Arizona as soon as possible.
My work load is demanding enough that I do not have time to fly back and forth and I am therefore staying at an Extended Stay Hotel close to company Z and renting a car and receiving a per-diem to help offset expenses.
Issue:
Company X is withholding NJ state income taxes and not AZ state income taxes in my paychecks.
Question:
Since I am on a short-term assignment (less than 12 months) is it correct for them to withhold New Jersey income taxes in my paycheck? And if this is the case, do I need to file a partial-year return with AZ and NJ for this tax year? Or do I have to pay both Arizona and New Jersey state income taxes for income on this work arrangement?
Thanks for your help.
