Modifies eligibility for alternative business calculation adjustment allowed under gross income tax.

This bill modifies New Jersey's gross income tax by introducing income limits for a specific tax adjustment that allows businesses to offset losses in one category against gains in another. Under the new rules, taxpayers with gross income of $500,000 or less will retain the ability to deduct 50 percent of their calculated business increment from their taxable income. For those earning between $500,000 and $1 million, the deduction is reduced to 25 percent, while individuals with gross income exceeding $1 million will no longer be eligible for any deduction. The legislation also clarifies that losses from this calculation can be carried forward for up to 20 taxable years to offset future income.
