N.J. Stat. § 54:4-1.14
The Legislature finds and declares that since 1979 New Jersey has lost a major share of its manufacturing jobs and manufacturing plants and this trend has persisted throughout periods of economic recovery and periods of recession. The Legislature also finds that New Jersey's manufacturing sector, notwithstanding the recent losses, continues to be an important source of relatively high-paying employment for a large portion of the work force and an essential foundation for the rest of the economy, serving as a larger multiplier of jobs in the economy than any other sector. The Legislature further finds that in order to retain manufacturing jobs it is in the interest of the business community, municipalities and the State of New Jersey to maintain a policy regarding the taxation of business personal property which is historically consistent, equitable and competitive with neighboring states and which creates and maintains reasonable incentives for manufacturing interests to exist and thrive in New Jersey. The Legislature, therefore, declares that it is the policy of the State, through this act, to refine the definitions of real property and personal property in order to reaffirm the broad exclusion from local property taxes of business personal property used or held for use in business.
