How Much Does Farm Assessment Reduce Taxes in NJ?

New Jersey’s Farmland Assessment Act can cut the land portion of your property tax bill by 97% or more, and a farm assessment tax reduction in NJ works by replacing the land’s market value on the tax rolls with a much lower agricultural productivity value. For 2026, qualifying cropland is assessed at roughly $100 to $1,250 per acre depending on soil quality and county, while that same land might carry a market value of $50,000, $100,000, or considerably more.¹ In a state where the average property tax bill already exceeds $10,000, the gap between those two numbers is where the savings live.

What the Reduction Looks Like in Real Numbers

Every New Jersey property tax bill is the assessed value multiplied by the local tax rate. For most owners, assessed value tracks what a willing buyer would pay. The Farmland Assessment Act swaps that market figure for a productivity value set annually by the State Farmland Evaluation Advisory Committee (FEAC), reflecting what the soil can grow rather than what a developer would build on it.²

Put real numbers on it. Ten acres of cropland in Burlington County carries a 2026 farmland assessment of about $800 per acre, or $8,000 total.³ If that same land sits in a growing suburb where market value runs $75,000 per acre, standard assessed value would be $750,000. At a typical New Jersey tax rate, annual taxes on the farmland-assessed parcel land in the neighborhood of $175, while the market-assessed version could exceed $16,000. That is the difference between farming being viable and being priced off your own land.

What Gets Reduced and What Doesn’t

The reduction applies only to land, not to buildings. Your farmhouse, barns, equipment sheds, and any other structures continue to be taxed at their full market value. The residential lot immediately under and around the house is also carved out and taxed at market rates.² What drops is the acreage devoted to agriculture, horticulture, or managed woodland, which in most farms is the biggest piece of the tax bill.

The 2026 FEAC Rates and How They’re Set

FEAC publishes new productivity values every year, broken down by county, soil quality, and land use. Your municipal assessor matches the soil types on your property (mapped by the Rutgers Cooperative Soil Survey) to one of five soil groups and then looks up the corresponding rate.⁴

Group A (very productive): the best farmland in the area. Cropland values in 2026 run about $840 to $1,248 per acre depending on county.
Group B (good): reliably productive soil, typically $700 to $1,080 per acre for cropland.
Group C (fair): lower yields from drought, excess moisture, or shallow soil.
Group D (poor): usually too wet, stony, or dry for permanent cultivation.
Group E (very poor): often found in pasture or woodland, with cropland values as low as $104 per acre.

Land use matters as much as soil quality. Harvested cropland gets the highest per-acre assessment, followed by cropland pastured, then permanent pasture, then woodland. Appurtenant woodland, meaning timber tied to the farm operation, sits at the bottom, sometimes as little as $35 to $57 per acre.¹ The assessor cross-references your soil group with your land use category, arrives at the per-acre value, and multiplies by the local tax rate.

Who Qualifies

Planting a garden won’t do it. You have to meet every one of these standards, and the assessor will check.

Minimum acreage: at least five acres actively devoted to farming or horticulture. The land under and around the farmhouse does not count toward the five.⁵
Two-year history: the land must have been in agricultural or horticultural use for at least two consecutive years immediately before the tax year you’re applying for.
Gross sales on the first five acres: at least $1,000 per year, averaged over the two preceding years. This includes crop and livestock sales, federal soil conservation payments, and fees for breeding, raising, or boarding livestock.²
Additional acreage: each acre beyond five must generate another $5 in gross sales.
Woodland and wetland exception: for acreage above five classified as woodland or wetland, the threshold drops to $0.50 per acre.²

Land managed under a woodland management plan has its own rule. If your first five acres are managed forest rather than traditional cropland or pasture, the minimum gross sales threshold for those acres is $500 rather than $1,000.²

Income figures aren’t casual estimates. You need documentation: receipts, invoices, and copies of Schedule F from your federal tax return. Keep them organized by year. When an assessor questions eligibility, the paper trail is the first thing they ask for.

How to Apply

The application form is FA-1, available from your municipal tax assessor.⁶ If your property includes managed woodland, you also complete a Woodland Data Form (WD-1), which requires certification from a professional forester that the woods are being managed under a written plan.

Along with the forms, submit an activity map showing which parts of the property are used for crops, livestock, pasture, woodland, and residential purposes. Attach income documentation covering the two preceding years.

The August 1 Deadline

Your completed FA-1, supporting documents, and activity map must be filed with the municipal assessor by August 1 of the year before the tax year you want the reduced assessment.⁶ Late applications are denied. This is not a soft deadline. The only statutory exception is illness: if a physician certifies that you were physically unable to file on time, the assessor may extend the deadline to September 1.⁵ No other excuse qualifies under the statute — not a family emergency, not a postal delay, not confusion about the date.

Missing the deadline is painful but not permanent. You can apply the following year for the next tax year. The cost is one year of full market-value taxes on land that would otherwise be assessed at a fraction of that amount.

Inspections

After you file, expect the assessor to visit. They’re looking for evidence of actual agricultural activity: active cultivation, livestock, managed timber, maintained pasture. A field that has clearly gone fallow or a barn with no animals will raise questions. The inspection is how the municipality confirms that the paper application matches reality before certifying the lower rate.

If Your Application Is Denied

If the assessor denies farmland assessment, you must receive a written notice by November 1 explaining the reasons and informing you of your right to appeal.⁷ The process has two levels.

County Board of Taxation: file Appeal Form A-1 with the county board by the following April 1. This is the first step and the one most owners take.
Tax Court of New Jersey: if the county board rules against you, you can appeal that decision to the state Tax Court.

Common reasons for denial include insufficient gross sales documentation, land that has not been in agricultural use for the required two years, and acreage that falls below five acres once the farmhouse lot is excluded. If the denial letter cites a documentation shortfall, gather stronger records before appealing. The county board wants proof.

Rollback Taxes When You Stop Farming

Converting farm-assessed land to residential, commercial, or any other non-agricultural use triggers rollback taxes. The rollback equals the difference between what you paid under farmland assessment and what you would have paid at full market value, calculated for the year of the change plus the two preceding tax years, a three-year recapture.⁸

On a property where farmland assessment saved $15,000 a year, the rollback could easily exceed $45,000. It catches people off guard when they sell to a developer or subdivide part of their acreage.

The rollback is triggered by the change in land use, not by a change in ownership. Sell the farm to another farmer who continues the operation, and no rollback applies. There is also a statutory exemption: land acquired by the state, a local government, a qualifying tax-exempt nonprofit, or the Palisades Interstate Park Commission for recreation and conservation purposes is not subject to rollback taxes.⁸ Selling development rights or donating a conservation easement should not trigger the penalty the program was designed to prevent.
