New Jersey self-employment tax, explained
New Jersey's progressive brackets climb quickly for the self-employed — the 6.37% rate starts at just $75,000 of taxable income for single filers, well before most freelancers expect to hit a near-top bracket.
Self-employment (SE) tax is the same everywhere — 15.3% of 92.35% of your net profit, split between Social Security (12.4%, up to the annual wage base) and Medicare (2.9%, uncapped). What changes by state is the income tax layer on top: New Jersey has a progressive income tax with a top rate of 10.75%, applied to your taxable income after federal deductions. For filing status, New Jersey's tax uses separately-scaled brackets for joint filers that aren't simply double the single-filer thresholds.

Frequently asked questions
What is the New Jersey state income tax rate for 1099 income?
New Jersey has a progressive income tax with a top rate of 10.75%. Its tax uses separately-scaled brackets for joint filers that aren't simply double the single-filer thresholds. See the "New Jersey self-employment tax, explained" section above for how it applies to your specific numbers.
How is self-employment tax calculated?
Self-employment tax is 15.3% of your net self-employment earnings (92.35% of net profit): 12.4% Social Security up to the annual wage base, plus 2.9% Medicare on all net earnings. If your combined income exceeds the Additional Medicare Tax threshold for your filing status, an extra 0.9% applies above that threshold.
What's the difference between self-employment tax and income tax?
Self-employment tax funds Social Security and Medicare — it's the self-employed equivalent of the payroll taxes an employer would otherwise split with you. Federal (and state) income tax is separate, calculated on your taxable income after deductions like the standard deduction and the QBI deduction.
