New Jersey 2026 Tax Changes — What Residents & Business Owners Must Know
Starting January 1, 2026, major federal tax changes take effect as key provisions of the Tax Cuts and Jobs Act (TCJA) expire and updated rules continue under the One Big Beautiful Bill Act (OBBBA).
New Jersey residents — who already face one of the highest state tax burdens in the country — will feel these federal changes more than most states because federal AGI flows directly into New Jersey’s tax system.
- W-2 earners across Newark, Jersey City, Hoboken, Paterson, Elizabeth, and the suburbs
- Commuters working in New York or Philadelphia
- Self-employed professionals, freelancers, and contractors
- LLCs and S-Corps operating in New Jersey
- Real estate investors and rental property owners
- Families with children
- Retirees drawing taxable retirement income
- Dual-income households in dense metro areas
Below is the full New Jersey–specific breakdown of what changes in 2026.
Key Federal Changes Affecting New Jersey Residents
Standard Deduction Shrinks
TCJA temporarily increased the standard deduction, but OBBBA did not extend it.
In 2026, the deduction drops significantly:
This is especially impactful in New Jersey, where high living costs make deductions critical.
Federal Tax Brackets Increase
With the end of TCJA’s lower brackets, 2026 federal tax rates rise:
New Jersey residents — especially those earning $80K–$400K — will see a significant increase in federal tax liability.
Residents in high-cost areas such as Bergen, Essex, Hudson, and Middlesex counties are especially affected.
QBI Deduction Made Permanent Under OBBBA
- LLCs
- S-Corps
- Sole proprietors
- Contractors and freelancers
- Qualified rental operations
This is a major win for New Jersey’s dense population of self-employed and high-income service professionals.
However, updated 2026 QBI rules include new income thresholds and stricter documentation requirements.
Child Tax Credit Shrinks
- from about $2,000
- to roughly $1,000 per child
Refundability also decreases, which affects many New Jersey families with high childcare costs.
Marriage Penalty Returns
TCJA temporarily eased the marriage penalty; OBBBA left that provision to expire.
In 2026:
- Married couples will reach higher brackets more quickly
- Combined incomes reduce credit eligibility sooner
- Many NJ metro-area dual-income households will feel the impact immediately
This affects a very large percentage of households in suburban counties.
