S-corporation transacting business in NJ - regardless where it is originally registered - will be under NJ jurisdiction
Please be aware that in NJ - a corporation must file Form CBT-2553 to elect to be treated as a New Jersey S corporation.
A corporation which is an S corporation for Federal purposes but does not elect S corporation status for State purposes would be subject to the corporate tax rates for ordinary corporations.

Correspondingly - income passed to you as a shareholder of S-corporation that is from NJ sources will be taxed for you on NJ state level.
