My son lives in PA but works in NJ. He received two W-2's for the job. Which state does he submit a state tax return in?

[JessicaJ · Accepted solution]

He should only have to file PA if no NJ taxes were withheld.  According to the state of NJ:

Pennsylvania residents who receive compensation from New Jersey sources are not subject to New Jersey income tax on those earnings.

If you are a Pennsylvania resident and your employer withheld New Jersey income tax from your wages, you must file a New Jersey nonresident return to obtain a refund.
