Beleaguered New Jersey property tax payers could get a break under a plan being considered by lawmakers to limit property taxes to a percentage of their household income or by restricting how much property value is taxed. The Legislature has been studying property tax reform options for about two months, with lawmakers giving themselves until Nov. 15 to recommend changes that would be enacted by the end of the year. The average New Jerseyan pays about $6,000 in property taxes, twice the national average. In recent years, the tax has increased about 7 percent annually. If implemented, the plan revealed Tuesday by legislative leaders called a “property tax circuit breaker” in other states could either limit property taxes to a percentage of household income or restrict the percentage of property value upon which property taxes are calculated. The idea is called a circuit breaker because it shuts off property tax bills, much like a circuit breaker shuts off electrical current, when they’re about to overload a household. New Jersey properties are taxed at 100 percent of their assessed value. Income isn’t considered when determining how much property taxes a property owner pays in New Jersey, except for special breaks offered to senior citizens and veterans. Other states have adopted circuit breakers to make property taxes fairer by tying them to income, helping those most burdened by property taxes. The Institute on Taxation and Economic Policy, which studies tax issues, said 35 states have some form of circuit breaker, but use them differently.
