Quarterly Estimated Tax Calculator — New Jersey (2026)
If you earn income in New Jersey without withholding — freelancing, contracting, rentals, dividends — the IRS expects payment four times a year, not once. This calculator turns your expected 2026 net profit into a per-quarter number covering self-employment tax, federal income tax and New Jersey state tax. 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.

2026 due dates and safe harbor
Federal estimated payments are due April 15, June 15, September 15 of 2026 and January 15 of 2027. You avoid penalties by paying either 90% of the current year's liability or 100% of last year's (110% if prior-year AGI exceeded $150,000) — the safe-harbor rule.
New Jersey runs its own estimated-payment schedule that usually mirrors the federal dates. On $90,000 of net profit the New Jersey portion alone is about $800 per quarter.
Underpayment penalties
The IRS charges interest-style penalties per quarter you fall short, currently around 7–8% annualized. Paying late in the year does not fix an early-quarter shortfall unless you use the annualized income method on Form 2210.
Irregular income is common in pharma work around Newark: if Q1 is slow and Q4 is huge, the annualized method usually beats four equal payments.
Paying as a New Jersey taxpayer
Pay federally through IRS Direct Pay or EFTPS, and New Jersey through the state revenue department's online portal — keep confirmation numbers for both.
New Jersey has no separate city or county income tax, so the state figure above is the full sub-federal income tax you pay.
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.
