| State | State income tax | Total tax | Set aside | vs New Jersey |
|---|---|---|---|---|

What's different about New Jersey for the self-employed
- New Jersey taxes business profit without the federal deduction for half of self-employment tax, and it does not allow SEP or solo 401(k) deductions. This estimate adds the half back.
- No tax is due if New Jersey gross income is $10,000 or less ($20,000 joint or head of household). No local income taxes on individuals.
- Businesses registered to collect sales tax must file the quarterly Sales and Use Tax return (Form ST-50) every 3 months even if no tax was collected; returns are due by the 20th day of the month after the period ends.
New Jersey estimated payments and deadlines
New Jersey collects its own estimated income tax with Form NJ-1040-ES, separately from the IRS. Required if you expect to owe more than $400 in New Jersey Income Tax when you file, after withholding and credits.
