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.
