Allows gross income tax credit for volunteer firefighters.

This bill creates a $500 tax credit against New Jersey's gross income tax for eligible volunteer firefighters. To qualify, a taxpayer must have been an active member of a volunteer fire company or part-paid fire department for three consecutive years (including the current tax year and the two prior years). The credit applies to New Jersey gross income tax liability but cannot reduce the tax below zero. It directly benefits volunteer firefighters who meet the service requirements, providing a financial incentive for their service.
