New Jersey Farmland Assessment for Landowners: What Luxury Property Owners in Morris and Somerset Counties Should Know

For landowners in high-value markets like Morris and Somerset Counties, where estate and acreage properties often include a blend of residential, wooded, and open land, this program can provide meaningful tax savings when portions of the property are actively devoted to agriculture.  The program applies only to land used for qualifying agricultural or horticultural purposes. Homes, landscaped areas, pools, and septic fields do not qualify. This allows many luxury property owners to benefit from the program while maintaining their residence and landscaped portions separately

Farmland assessment, in plain English

New Jersey’s farmland assessment allows land that is actively used for agriculture to be assessed at its agricultural value instead of full market value. It is designed to encourage ongoing agricultural use and can lower your annual property tax bill while your land qualifies. The program is created by state statute and administered by your local tax assessor.

Eligibility and Requirements

To qualify, a landowner must generally prove that at least five acres of their property are actively devoted to agriculture or horticulture. When a home is present, at least one acre is typically excluded from that total, meaning six or more acres may be required for most estate properties.

Agricultural activity must take place annually or periodically, and income must be generated from what is grown or produced on the property. The law sets a minimum annual income threshold, typically $500 for the first five acres with small incremental amounts for each additional acre, depending on the land’s classification.

Properties that are more than 50% wooded must also have an approved Forest Management Plan (also called a Woodland Management or Forest Stewardship Plan). This plan documents the property’s forest characteristics, wildlife and soil conditions, and a 10-year schedule of activities proving that the land is being managed for agricultural purposes through sustainable forestry practices.

Costs, Savings, and Long-Term Considerations

The local tax assessor determines the precise value of the qualifying acreage. On average, cropland may be assessed at roughly $800 per acre, pastureland at about $200 per acre, and woodland at $150 per acre or less, depending on the municipality.

While this can translate to substantial annual savings, landowners should also consider management costs such as forestry services, agricultural inputs, or time spent on documentation.
Farmland Assessment is not automatic — it requires continued effort, organization, and compliance to maintain.

Why It Matters for Luxury Property Owners

For luxury buyers and sellers in Morris and Somerset Counties, Farmland Assessment offers both financial and lifestyle benefits.
Sellers can highlight qualifying acreage as a value-enhancing feature that reduces carrying costs, while buyers can leverage the program to maintain scenic acreage with tax efficiency.

Beyond the numbers, Farmland Assessment reflects a commitment to environmental stewardship, aligning beautifully with the timeless appeal of New Jersey’s rural landscapes.

Roll-back taxes and how to plan for them

If the land stops qualifying for farmland assessment, municipalities often impose roll-back taxes. This recaptures the difference between what you paid under farmland assessment and what you would have paid at full market assessment for a statutory look-back period, sometimes with interest. The look-back period and calculation are set by state statute and local practice. Do not assume a specific number of years. Confirm details with the Township assessor and consult a qualified professional before changing use.

Ways to reduce roll-back risk

• Keep a consistent, well-documented agricultural activity year after year.
• Use a written commercial lease if you rent to a bona fide farmer and retain documentation of production and sales.
• If you expect a future conversion to non-agricultural use, include potential roll-back taxes in your budgets and timelines.
• Explore conservation options or preservation programs if long-term agriculture aligns with your goals.
• Discuss scenarios with the municipal assessor before subdividing, building, or converting any portion of the land.
