New Jersey does not have a standard deduction. It uses a personal exemption system instead.
Critical difference: New Jersey does NOT start from federal AGI or federal taxable income. NJ has its own gross income definition (NJ Gross Income) with its own categories of income.
NJ Gross Income includes income from 18 categories defined in N.J.S.A. 54A:5-1, including:

Tier 2 rules — requires judgment
| Rule ID | Situation | Guidance |
|---|---|---|
| NJ-T2-01 | Multi-state income: Taxpayer earns income in another state | NJ taxes worldwide income of residents. Credit for taxes paid to other states available. Complex for NY/NJ commuters — verify convenience-of-the-employer issues. |
| NJ-T2-02 | NY/NJ commuter tax interaction | NJ residents working in NY pay NY tax on NY-source income and get a credit on their NJ return. However, NJ may challenge the credit if the NY tax was based on the convenience-of-the-employer rule. |
| NJ-T2-03 | Business income categorization | NJ's 18 income categories can create allocation issues for self-employed taxpayers with mixed income types. Review whether income should be "net profits from business" or another category. |
| NJ-T2-04 | PTET/BAIT election | NJ's Pass-Through Business Alternative Income Tax allows certain pass-throughs to pay entity-level tax. Not applicable to sole proprietors but relevant for multi-member LLCs. |
| NJ-T2-05 | Federal conformity for depreciation | Verify NJ's current position on federal bonus depreciation and OBBBA changes. NJ's non-conformity with certain federal provisions may require separate depreciation schedules. |
