Re-establishes 6.37 percent as top marginal gross income tax rate.

This bill amends New Jersey's income tax code to re-establish 6.37% as the top marginal tax rate for high-income earners. It specifically sets this rate for taxpayers with taxable income over $150,000 for married couples filing jointly (or over $75,000 for single filers) for taxable years beginning on or after January 1, 2023. The bill restores a tax rate that was in effect from 2004 to 2005, before being replaced with higher rates. This change affects the highest income brackets while leaving lower tax rates unchanged.
