If you are buying a home in Monmouth County in 2026, property taxes should be part of your monthly budget from day one. In New Jersey, the number that matters is not just the list price. It is the relationship between a home’s assessed value and the local tax rate. The State of New Jersey says the general tax rate is the figure used to compute the tax bill, and it is expressed as dollars per $100 of taxable assessed value.
The most recent official statewide tables available as of April 2026 are the 2025 certified tax rate and average residential tax bill reports. For Monmouth County, the 2025 average residential tax bill was $11,664, with an average residential assessment of $782,446.
What buyers need to know first
A lower tax rate does not always mean a lower tax bill. Some Monmouth County towns have very low effective tax rates, but home values and assessments there are much higher. That is why buyers shopping in towns near the shore or in luxury markets can still see very large annual tax bills.
That also means two homes with the same sale price can carry very different taxes depending on the town, the assessment, and whether the property was recently reassessed.
Monmouth County property tax snapshot for 2026 buyers
Here is the clearest way to think about Monmouth County taxes right now.
The countywide average residential tax bill is $11,664. Towns above that number will often feel heavier on carrying costs, while towns below that number may offer more breathing room for buyers who are focused on monthly affordability.
Among Monmouth County municipalities in the 2025 state tax rate table, some of the lowest effective tax rates were Spring Lake at 0.444, Deal at 0.435, Allenhurst at 0.528, Sea Girt at 0.520, and Avon by the Sea at 0.710. Some of the highest effective tax rates were Keansburg at 2.429, Roosevelt at 2.417, Allentown at 2.360, Matawan at 2.263, and Union Beach at 2.254.
Towns where buyers often see higher tax bills
If you are searching in higher end markets, it is common to see larger annual property tax numbers even when the rate looks modest.
Deal had an average residential tax bill of $25,585 in the 2025 state report. Rumson came in at $23,607. Allenhurst was $19,654. Fair Haven was $18,950. Colts Neck was $17,589. Holmdel was $15,893. These towns also had comparatively high average residential assessments, which helps explain the larger bills.
This is one reason buyers moving from another county or another state can be surprised. A town with strong schools, larger lot sizes, or a prime coastal location may still feel expensive to carry even if the headline tax rate looks reasonable.
Towns where buyers may find lower annual tax bills
Several Monmouth County towns posted lower average residential tax bills in the latest official report.
Keansburg had an average residential tax bill of $7,478. Tinton Falls was $8,456. South Belmar, now Lake Como in the tax tables, was $8,254. Freehold Borough was $8,842. Highlands was $8,985. Aberdeen was $9,027.
That does not automatically make those towns cheaper overall. Home prices, flood exposure, commuting needs, and inventory all matter too. But for buyers watching their monthly payment closely, these towns may deserve a closer look.
A few buyer friendly examples
Middletown Township had an average residential tax bill of $11,666, almost exactly in line with the county average. Marlboro Township was higher at $12,779. Manalapan Township was $11,343. Howell Township was $9,885. Wall Township was $10,477. Red Bank was $10,937. Long Branch was $12,635.
For many buyers, this is where comparison shopping gets real. A home in one town may have a similar price tag to a home in another, but the annual tax difference can still change your monthly payment by hundreds of dollars.
How to estimate taxes on a specific home
New Jersey’s Division of Taxation explains that the general tax rate is applied per $100 of assessed value. In simple terms, you can estimate taxes by dividing the assessed value by 100 and multiplying by the general tax rate.
For example, if a home is assessed at $500,000 in a town with a general tax rate of 1.824, the estimated tax bill would be about $9,120. That is only an estimate, but it is a good starting point when comparing listings.
Why tax bills can vary even inside the same town
Property taxes are based on assessed value, not just the current market price. New Jersey notes that properties are assessed locally and submitted annually to the county board of taxation. That means a buyer should always verify the current assessment and the latest tax record for the exact property, rather than relying only on countywide averages.
This matters even more in Monmouth County because home values vary widely from inland neighborhoods to waterfront communities. A town average is useful for planning, but it is never a substitute for checking the actual tax bill on the property you want to buy.
The bottom line for 2026 buyers
For buyers entering the Monmouth County market in 2026, the smartest approach is to compare both home price and annual taxes together. The latest official data shows a county average residential tax bill of $11,664, but real town to town differences are significant. Some buyers will find lower carrying costs in places like Keansburg, Tinton Falls, or Freehold Borough, while others shopping in Deal, Rumson, Fair Haven, Colts Neck, or Holmdel should expect much higher tax bills.
