Self-Employed Tax Calculator — New Jersey (2026)
Self-employed in New Jersey? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and New Jersey state income tax. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. New Jersey uses a progressive income tax with 7 brackets running from 1.40% up to 10.75%, applied after a state standard deduction of $0.

Self-employment tax vs New Jersey income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
New Jersey then taxes essentially the same profit figure at 1.40%–10.75%. On $80,000 of net profit that adds roughly $2,615 to the bill.
New Jersey has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Deductions that matter for New Jersey freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax, and New Jersey tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable pharma contractor in Newark.
Working for yourself in New Jersey
New Jersey's economy leans on pharma, finance, and logistics, which shapes the contractor market around Newark — and your fixed costs. With one-bedroom rent near $1,900, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
New Jersey's 10.75% top rate above $1M is tied with DC for one of the highest US sub-national income tax rates outside California.
Local and payroll taxes New Jersey adds on top
Employee contributions for temporary disability, family leave and unemployment add roughly 0.4% of wages. That deduction sits outside the federal and state income tax lines, so build it into your own budget on top of the numbers above.
New Jersey has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
Nobody withholds these for you when you are self-employed in New Jersey. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from New Jersey
New Jersey holds income-tax reciprocity agreements with Pennsylvania. If you commute between them, your wages are taxed only by your state of residence — file the exemption certificate with your employer so the wrong state is not withheld from every paycheck.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Newark resident spending part of the year at a client site in Pennsylvania may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your New Jersey tax bill
New Jersey charges a 6.625% state sales tax, homeowners pay an average effective property tax of 2.23% of market value, and the minimum wage in force during 2026 is $15.92 an hour.
6.625% statewide, halved in designated Urban Enterprise Zones.
Income tax is only one part of a state's take. New Jersey recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. New Jersey exempts Social Security and allows a pension exclusion up to $100,000 for filers 62+ under income limits.
New Jersey vs Pennsylvania on the same salary
On a $90,000 salary, a single filer keeps about $68,538 a year in New Jersey against roughly $69,382 in Pennsylvania — a difference of $844, or $70 a month.
Effective combined rates are 23.8% in New Jersey and 22.9% in Pennsylvania. Set that gap against living costs: index 114 here versus 95 there, with property tax at 2.23% and 1.49% respectively.
