New Jersey runs a progressive state income tax with 7 brackets, topping out at 10.75% for the highest earners. Lower-income filers pay a much smaller marginal rate; the effective rate rises with income because only the portion of wages within each band is taxed at that band's rate. New Jersey's state standard deduction is $1,000 for single filers and $2,000 for married couples filing jointly in 2026.
Self-employed and 1099 filers in New Jersey owe the 15.3% federal self-employment tax (12.4% Social Security up to the wage base, 2.9% Medicare with no cap) on net earnings, plus federal income tax and New Jersey state tax up to 10.75%. On $100,000 of gross 1099 income with $15,000 of deductible business expenses, the estimated total tax burden in New Jersey is about $23,402.97, leaving roughly $61,597.03 take-home (effective rate 27.53%). New Jersey freelancers also generally need to make quarterly estimated payments to the IRS and New Jersey Division of Taxation to avoid underpayment penalties.
Data current as of 2026; verify with New Jersey Division of Taxation (https://www.nj.gov/treasury/taxation/taxtables.shtml) before relying on these figures for filing.

On $75,000 of gross 1099 income (single filer, $11,250 in deductible business expenses, 2026), a New Jersey freelancer owes about $9,007.59 in self-employment tax, $4,929.54 in federal income tax, and $1,726.57 in New Jersey state tax — total roughly $15,663.71 (effective rate 24.57%).

Self-employment tax in New Jersey (and everywhere in the US) is 15.3% on the first portion of net earnings: 12.4% Social Security (capped at the annual wage base) plus 2.9% Medicare (no cap, plus 0.9% additional Medicare above $200,000 single). It is calculated on net earnings × 92.35% to mirror the FICA tax employees would pay. New Jersey does not levy a separate self-employment tax, but state income tax up to 10.75% still applies to net business income.
Yes. If you expect to owe at least $1,000 in federal tax after withholding, the IRS requires quarterly estimated payments (April, June, September, January). New Jersey also requires quarterly state estimated payments to avoid underpayment penalties; due dates generally mirror the federal schedule.
New Jersey is workable for freelancers, though state income tax up to 10.75% reduces take-home compared with no-income-tax states. Other factors matter: cost of living, sales tax on services (varies by state), health insurance market, and local business license costs. New Jersey's $560,000 median home price is also part of the calculus.
Common federal deductions for New Jersey self-employed filers include: home-office (simplified $5/sqft or actual expense method), health-insurance premium deduction (above-the-line), self-employment tax deduction (half of SE tax), retirement contributions (SEP-IRA, Solo 401(k)), business mileage (70¢/mile for 2026), startup costs (up to $5,000 first year), and the Qualified Business Income (QBI) deduction (up to 20% of qualified income, subject to thresholds). New Jersey generally conforms to most federal business deductions for state purposes, with state-specific add-backs.
On $100,000 gross 1099 income with $15,000 expenses, estimated total tax is $23,402.97 in New Jersey vs $24,541.77 in Delaware. New Jersey comes out lower by about $1,138.81 per year for this scenario.
