Requires combined groups to be determined on world-wide basis under corporation business tax.

This bill requires corporations in New Jersey that file combined tax returns to calculate their total income on a worldwide basis rather than limiting calculations to income generated within the state. The law mandates that companies include the full net income of all their foreign branches and subsidiaries, adjusting these figures to align with U.S. accounting standards and converting them into U.S. dollars. It also updates how partnership income is counted within these groups and clarifies rules for foreign corporations with existing tax treaties to ensure consistent reporting across all entities in the group.
