Frequently Asked Questions

What is the NY convenience rule?

For an NJ resident working remotely for a NY employer, New York's 'convenience of the employer' rule can affect the sourcing of work-from-home days. Apply the rule to the actual employer requirements, work locations, and tax year rather than assuming a remote day is sourced to either state. Employer necessity and New York's bona fide employer-office test require separate fact review.

Do NJ and PA have a reciprocal agreement?

Yes, but only for qualifying employee compensation. NJ and PA generally do not impose state personal income tax on that compensation when earned by a resident of the other state. The agreement does not cover self-employment, business, rental, or investment income, and PA local earned-income tax or Philadelphia wage tax requires separate analysis.

How does the credit for taxes paid to other states work?

If you are a NJ resident and pay tax to another state on income earned there, NJ allows a credit on Schedule NJ-COJ. The credit equals the lesser of the actual tax paid to the other state or the proportional NJ tax on that income. This prevents double taxation.
