State Tax Day - Current, S.13, New Jersey—Personal Income Tax: Reduced Business Deduction For High-Income Taxpayers Enacted, (Jul 2, 2026)
New Jersey has modified the state's personal income tax alternative business calculation adjustment by adjusting eligibility. Retroactive to tax years beginning on or after January 1, 2026, the percentage that a taxpayer can subtract from taxable income is determined as follows:
a taxpayer with gross income of no more than $500,000 for the tax year can subtract from taxable income 50% of the business increment;
a taxpayer with gross income of more than $500,000, but no more than $1,000,000 for the tax year can subtract from taxable income 25% of the business increment; and
a taxpayer with gross income over $1 million for the tax year cannot subtract any percentage of the business increment.
Previously, all eligible taxpayers could deduct 50% of the business increment, regardless of income.
