I am a NJ resident and I have a NJ-based S corporation. My S corporation gets paid (for the services I am rendering while residing in NJ) on a K1 from a New York City-based company. Am I liable for NY taxes under those circumstances? Thanks!

" My S corporation gets paid (for the services I am rendering while residing in NJ) on a K1 from a New York City-based company.

Howver, you can (claim credit) or are eligible for a credit against the income tax you owe to NJ.
