I live in New Jersey where the average total per-pupil cost in NJ 2017-2018 was $21,866. That is higher than most states. The majority of the revenue to pay for it comes from property taxes. New Jersey is an economically diverse state with among the richest towns in the country and towns that are very poor indeed, yet all our municipal school districts rely on local property taxes. The state’s average residential school tax bill in 2018 was $4,610 per household, about 52% of the total municipal tax bill. The rest pays for municipal services.
To relieve the unfair tax burdens created when economically depressed communities are unable to equitably fund public schools, the State collects an income tax, part of which is distributed to school districts that need financial assistance. The school aid formulas, however, are subjected to considerable political pressures resulting in unsatisfactory, often hotly disputed results. The overall funding complexities of how property taxes and state aid are calculated are nearly impossible to sort out and massively confusing for most taxpayers to fathom. No methods for directly comparing school taxes across municipal districts are perfect, but one of the better ways uses the "equalized tax rate".
The equalized tax rate is what a homeowner’s tax rate would look like if every house in NJ was assessed at 100 percent of what it will get on the open market. The equalized tax rate is a guide to compare homeowners' real tax burden across different towns. The average equalized tax rate in New Jersey was 2.287 percent in 2018. With this method and that median figure in mind, I grouped together five counties with the highest equalized tax rates (pays more per $100 in assessed property value) and the five counties with the lowest equalized tax rate. I then looked at the differences between these groups. It isn’t the greatest method, but it does bring out some of the inequities of property taxes.
The group of the five counties with the highest equalized tax rates in New Jersey is comprised of Camden (3.5%), Gloucester (3.2%), Passaic (3.0%), Warren (3.0%), and Cumberland (2.9%). The average of these five tax rates is 3.2 percent.
The group of five counties with the lowest equalized tax rates is comprised of Hudson (1.8%), Ocean (1.8%), Monmouth (1.8%), Bergen (2.2%), and Morris (2.2%). The average of these five tax rates is 1.9 percent.
The high tax rate group has less family income, $62,000 per year on average. The lower tax rate group has an average family income of $75,000 per year. The average value of homes in the high tax rate group is lower, $252,000, which is 72% less valuable than the average home value in the low tax rate group, which is $433,000.
Multiplying the average home values by the tax rate in the high tax rate group suggests a property tax bill of $7,762 per year and a tax bill of $8,486 in the low tax rate group. The difference in property taxes between the wealthier and poorer groups is only 9.3%, yet the difference in family income is 21% more income in the low tax rate group. Also, residential properties are 72% less valuable in the high tax rate/low-income group than in the wealthier-low tax rate group.
The argument has been made that the wealthier communities have fewer, but more expensive homes, and therefore homeowners pay more in property taxes. This is true in actual dollars per year, but it is not true in terms of property taxes bills as a percentage of family income or of the wealth, or future equity both groups will acquire in the years that their children are in school. As a form of wealth tax, local property taxes place a much higher burden on less wealthy communities. The band-aid we apply in New Jersey to fix the inequities, state aid to supplement educational costs in poorer communities, is a poor substitute for a more equitable school funding plan.
