New Jersey has no standard deduction; it subtracts a $1,000 personal exemption (tax year 2025) (New Jersey Division of Taxation — 2025 NJ-1040 instructions, line 6 (regular exemptions)). The deductible half of self-employment tax is not priced: New Jersey taxes net profits from business (NJ-1040 line 18) under its own rules, and its 2025 NJ-1040 instructions do not mention the deductible half of self-employment tax.

Frequently Asked Questions
How much New Jersey income tax is due on $70,000 of self-employment profit?
The calculator's New Jersey line is $2,375; New Jersey's own deduction or credit brings it to $2,320.
Does New Jersey expect its self-employed to pay tax during the year?
Yes, at this page's $70,000: the $2,320 New Jersey tax is over the $400 line, so unless at least 80% of it ($1,856, about $464 a quarter) is paid through estimated payments or withholding by the end of the year, the return can owe installment interest, figured on Form NJ-2210 and entered on line 52.
Where does business income go on the New Jersey return?
Schedule NJ-BUS-1, Part I, carries each business's net profit to NJ-1040 line 18, with a copy of the federal Schedule C attached. A loss puts nothing on line 18, but it may qualify for the alternative business calculation adjustment on Schedule NJ-BUS-2 (line 35), as may a loss that schedule carries forward from an earlier year. Self-employed health insurance is deducted through the medical expense worksheet (Worksheet F, line 5) onto line 31 (2025 NJ-1040 instructions, read 2026-10-22).
