All of your income is taxable to Pennsylvania, regardless of what state it was earned in.
You must file a New Jersey nonresident tax return if all income for the entire year was more than the filing threshold amount for your filing status. The 2018 filing threshold is $10,000 for single and married filing separately and $20,000 for all others.
