Provides 50 percent sales and use tax exemption for certain businesses in impacted municipalities during ongoing public highway project.

This bill provides a 50% exemption from New Jersey's sales and use tax for qualifying retail businesses operating in municipalities affected by ongoing public highway projects. It directly affects small businesses with a fixed location (such as shops or charter boat services) located in areas where highway construction, repair, or maintenance is underway. Businesses must apply to the Division of Taxation for approval, and the exemption applies only during the "relief period" - the time between a project's start and completion. The exemption automatically ends when the highway project concludes, as notified by the Commissioner of Transportation to the Tax Division.
