It depends but if you have to file a federal income tax return and you have VA sourced income (if you performed work in VA than you would have VA sourced income), you will need to file a VA nonresident state income tax return to report your VA income only.
You will also
need to file an NJ resident state tax return (for all income from all sources
including VA wages). You will get a state income tax credit in NJ for any VA
state income taxes that you paid on your nonresident VA state income tax return.
You
will want to work on your nonresident VA state income tax return first. You
will then take a tax credit from your nonresident VA state income taxes on your
resident NJ state income tax return. (Please note that you will only get a tax
credit for your VA state income taxes up to the amount of NJ state income taxes
that would have been paid if the income was earned in NJ). The credit for
taxes paid to another state section will be at the end of your residence
state's interview process.
Just
follow the TurboTax guide when working on your states (remembering to do your
nonresident state return first) and TurboTax will do all the calculations and
credits to your resident states return.
