Property Tax Bills Across Middlesex County, New Jersey
Property tax bills in Middlesex County are based on the assessed value of a home and the local tax rate set by taxing authorities. The bill is determined by multiplying the home’s assessed value by the applicable rate, so homeowners with higher-valued properties generally pay more.

With a median home price of $167,900, property taxes can still be substantial. The typical bill in the county is well above the national median property tax bill of $2,400, which means many homeowners face a larger annual expense than the average U.S. homeowner.
