The four different Millburn tax rates you'll find online
Search for Millburn's property tax rate and you will find several different numbers. Nobody is lying. Here is what each one actually measures, and how to work out a real bill.
This comes up in almost every buyer conversation, usually with real frustration: why does every website tell me a different tax rate for Millburn?
Nobody is lying to you. The numbers measure different things, and almost nobody explains which is which.
The formula that actually produces your bill
New Jersey property tax is arithmetic, not a mystery:
Annual tax = (Assessed Value ÷ 100) × General Tax Rate
If a home is assessed at $800,000 and the general tax rate is $2.019 per $100 of assessed value, the annual bill is $16,152. That is the number the tax collector uses.
The three things people confuse
- General tax rate. Dollars per $100 of assessed value. This is the number you multiply by. It is set annually by the municipality.
- Effective tax rate. Tax as a percentage of market value. Lower than the general rate, because assessments in New Jersey generally run below market value.
- Equalization ratio. Assessed value as a share of market value, set by the county. This is not a tax rate at all — it is the bridge between the other two.
Why the equalization ratio exists
New Jersey does not reassess every home every year. That means the assessed value on the books can drift well below what a house would actually sell for. If the ratio in a district is around 78%, assessed values are running at roughly 78% of market — so a house that would sell for $1,000,000 might be assessed near $780,000.
That single fact explains why an "effective rate" and a "general rate" look so different. They are dividing the same tax bill by two different denominators.
The mistake that costs people money
Buyers routinely take a published rate, multiply it by the purchase price, and get a number that is far too high. The rate applies to the assessed value, not the asking price. If assessments are running below market, that estimate can be off by a wide margin.
Always start from the assessed value on the tax record, and compare towns using the effective rate if you want a fair comparison between municipalities.
This is general information, not tax or legal advice, and not an appraisal. Tax rates, assessments and equalization ratios change annually and vary by municipality. Confirm current figures with the Millburn Township tax collector and the Essex County board of taxation before relying on them.
