What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Middlesex County, NJ

Middlesex County’s effective property tax rate of 2.098% lands squarely at New Jersey’s statewide median, ranking it 11th among the state’s 21 counties — a middle-of-the-pack position in one of the nation’s most heavily taxed states. That rate is far above the national median of 0.794%, so homeowners here pay roughly two and a half times what a comparable property would owe elsewhere in the country. On a median home value of $462,900, the annual real-estate tax bill comes to $9,712. With median household income at $111,549 and per-capita income of $50,601, that levy absorbs a meaningful share of earnings. Communities such as Edison, Plainfield, and Avenel reflect the county’s mix of suburban and urban settings. Buyers weighing a move to central New Jersey should expect property taxes to be a significant, ongoing cost rather than an afterthought.

Frequently asked questions

What is the property tax rate in Middlesex County, NJ?
The effective rate is 2.10% — meaning the median tax bill equals about 2.10% of the median home value.
How much are property taxes on a median home?
On the median home ($462,900), the estimated annual bill is about $9,712.
Is Middlesex County's rate high or low?
Compare it to the state median of 2.10% and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Middlesex County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Middlesex County assessor within the local deadline, typically with comparable sales as evidence.
