1. How New Jersey Apportionment & Economic Nexus Impact ASC 740 Tax Provisions
For multi-state C-Corporations and SaaS companies selling into New Jersey (NJ), exceeding $100,000 in annual NJ-sourced receipts (or maintaining remote W-2 employees inside the state) establishes nexus under New Jersey's Corporation Business Tax. Under 100% Single Sales apportionment and Market-Based rules, SaaS subscription revenue is sourced to New Jersey based on where the customer receives the benefit of the software.

- IRC §174 R&D Capitalization Rule in New Jersey: New Jersey conforms to the federal TCJA mandatory 5-year amortization of domestic research and experimental (R&E) expenditures under IRC §174. No state subtraction modification is permitted.
