How the New Jersey 1099 tax calculator works
A 1099 freelancer in New Jersey pays up to three taxes on the same profit: federal self-employment tax, federal income tax, and New Jersey income tax. All of them are figured on net profit, meaning what clients paid you minus deductible business expenses.
Self-employment tax is the Social Security and Medicare tax an employer would normally split with you. As a freelancer you pay both halves on Schedule SE, on 92.35% of your net profit:
Federal income tax then applies to what is left after three deductions: half of your self-employment tax, the standard deduction ($16,100 single, $32,200 married filing jointly in 2026) and, for most freelancers, the 20% qualified business income (QBI) deduction:
- SE
- Self-employment tax: Social Security plus Medicare on 92.35% of net profit
- QBI
- Qualified business income deduction: up to 20% of business profit, capped at 20% of taxable income
High earners also owe the 0.9% Additional Medicare Tax on self-employment earnings above $200,000 (single) or $250,000 (joint). The QBI deduction starts to phase out once taxable income passes $201,750 (single) and is gone $75,000 later; the calculator phases it out as for a business with no employees. For a specified service business, such as consulting, only the applicable percentage of the income counts in that range as well (IRC 199A(d)(3)), so the deduction shrinks faster; switch it on in the calculator. It also applies the $400 minimum deduction that starts in 2026 for anyone with at least $1,000 of qualified business income.
The estimate leaves out deductions that depend on your situation, such as the new deduction for people 65 and older (up to $6,000 each, 2025 through 2028) and the deduction for qualified tips.
New Jersey income tax
New Jersey has 7 income tax brackets, topping out at 10.75%. Before applying its rates, New Jersey allows a $1,000.00 personal exemption ($2,000.00 joint). The calculator subtracts those amounts from your federal AGI, applies the rates below and then subtracts any credits:
| Bracket | Single | Married filing jointly |
|---|---|---|
| 1 | 1.4% over $0.00 | 1.4% over $0.00 |
| 2 | 1.75% over $20,000.00 | 1.75% over $20,000.00 |
| 3 | 3.5% over $35,000.00 | 2.45% over $50,000.00 |
| 4 | 5.525% over $40,000.00 | 3.5% over $70,000.00 |
| 5 | 6.37% over $75,000.00 | 5.525% over $80,000.00 |
| 6 | 8.97% over $500,000.00 | 6.37% over $150,000.00 |
| 7 | 10.75% over $1,000,000.00 | 8.97% over $500,000.00 |
| 8 | — | 10.75% over $1,000,000.00 |
Local income taxes: Some jurisdictions in New Jersey levy payroll, flat-rate wage, or interest and dividend taxes. The calculator leaves them out.
State figures come from the Tax Foundation's table of 2026 rates and brackets, updated for laws passed later that apply to all of 2026. Confirm with the New Jersey Division of Taxation (opens in a new tab) before you file.
Worked example: New Jersey freelancers at three incomes
Here is the 2026 estimate for a single freelancer in New Jersey with no other income, taking the standard deduction and the QBI deduction:
| Net profit | Self-employment tax | Federal income tax | New Jersey income tax | Total | Effective rate |
|---|---|---|---|---|---|
| $50,000 | $7,064.78 | $2,667.29 | $1,019.59 | $10,751.66 | 21.5% |
| $100,000 | $14,129.55 | $8,235.00 | $3,730.02 | $26,094.57 | 26.1% |
| $150,000 | $21,194.33 | $16,413.30 | $6,690.01 | $44,297.64 | 29.5% |
At $100,000 of profit, self-employment tax is the largest single piece at $14,129.55, more than federal income tax of $8,235.00. New Jersey adds $3,730.02, bringing the total to $26,094.57, or $6,523.64 a quarter. Of the 50 states and D.C., New Jersey has the 30th-lowest state income tax bill at this income.
New Jersey vs. neighboring states
Taxes are one factor in where you live and work, and they change sharply across state lines. Here is the same $100,000 single freelancer in New Jersey and nearby states:
| State | State income tax | Total tax | Take-home pay |
|---|---|---|---|
| Pennsylvania | $2,853.11 | $25,217.66 | $74,782.34 |
| New Jersey | $3,730.02 | $26,094.57 | $73,905.43 |
| New York | $4,442.93 | $26,807.48 | $73,192.52 |
| Delaware | $4,792.72 | $27,157.27 | $72,842.73 |
Pennsylvania comes out lowest at $25,217.66 and Delaware highest at $27,157.27, a difference of $1,939.61 a year. Remember that a state's total tax burden also includes sales and property taxes, and that you generally owe income tax where you live and work, not where your clients are.
Every state's figure for one example freelancer is in the 1099 tax by state table, which you can sort and download.

Quarterly estimated taxes for New Jersey freelancers
No employer withholds tax from 1099 income, so the IRS expects you to pay during the year using Form 1040-ES. For 2026, the four payments are due April 15, June 15 and September 15, 2026, and January 15, 2027. You generally avoid an underpayment penalty if your payments cover at least 90% of this year's tax or 100% of last year's (110% if last year's AGI was above $150,000).
New Jersey income tax is paid separately. The New Jersey Division of Taxation has its own estimated payment forms; most states use the same quarterly dates as the IRS. The "Quarterly payments" view above splits your estimate into equal federal and state installments you can schedule now.
Ways to lower the bill
- Track every business expense. Software, equipment, a dedicated home office and business mileage all reduce net profit, which lowers all three taxes at once.
- Deduct self-employed health insurance and retirement contributions. A SEP-IRA or solo 401(k) can shelter a large share of freelance income from income tax.
- Keep the tax money separate. Moving your set-aside percentage into a high-yield savings account as each payment arrives earns interest until the quarterly due date.
The bottom line
A New Jersey freelancer's 1099 tax bill is mostly federal: on $100,000 of net profit, self-employment tax is $14,129.55 and federal income tax $8,235.00, with $3,730.02 of New Jersey income tax on top. All in, that is $26,094.57, or 26.1% of profit.
Set aside about that share of every payment, pay the IRS and the state each quarter, and rerun the New Jersey 1099 tax calculator when your income changes.
