It depends on your state of residence.
No - If you are a NJ or PA permanent resident and you are working at a NJ office/branch located in NJ but the company's headquarters is in NY.
In this instance, you will only need to file a NJ resident state income tax return.
Yes - If you are a NJ permanent resident and you are working remotely in NJ for a NY based company.
When it comes to filing state taxes, you will report
income in the state were the work is performed However, NY is one of the few
states that will also require you to file in NY if you work remotely but the
company is based in NY.
You will also need to report your wages in the state
where you are a permanent resident (if that state has a personal state income
tax filing requirement).
So if
you worked in NY or if you worked remotely for a company is located in NY but you are a resident of
another state, you will need to file a NY nonresident state income tax return
to report your NY-source income. (If NJ is not your state of residence and you
worked in NJ , then you will file a NJ nonresident state income tax return to
report NJ-source income and an resident state income tax return. This does not apply to PA residents under the wage reciprocal agreement.)
You
will then be able to get a tax credit on your resident state income tax
return for taxes paid on your nonresident state income tax return. (In
TurboTax, this information usually is listed towards the end of your resident
state tax return)
You
will want to work on your non-resident state tax return first. You will then
take a tax credit from your non-resident return on your resident state tax
return. (Please note that you will only get a tax credit for your nonresident
income taxes paid up to the amount of resident income taxes that would have
been paid if the income was earned in your resident state).
Just
follow the TurboTax guide when working on your states (remembering to do your
non-resident state return first) and TurboTax will do all the calculations and
credits to your resident states return
