Conservation easements: how they work, what they cost you, and the tax rules

Published September 30, 2026 · Easements.com research desk · Editorial advisor Joshua Cole, Attorney (ND)

A conservation easement is a voluntary, recorded agreement in which a landowner gives up some development rights, typically to a land trust or government agency, to protect farmland, habitat, scenic views or water quality. The owner keeps the land and can usually keep farming, living on or selling it, but every future owner is bound by the restrictions.

What gets restricted

Each easement is negotiated, so terms vary widely. Common restrictions limit subdivision, new houses, commercial uses and mining, while reserving existing homes, agriculture and sometimes a small number of future building sites. The holder monitors the land, usually annually, to confirm compliance.

Federal tax treatment

Donating a qualified conservation easement to a qualified organization can support a federal income tax deduction under Internal Revenue Code section 170(h), provided the easement is perpetual and serves a recognized conservation purpose. The IRS has flagged abusive syndicated conservation easement transactions, and it requires a qualified appraisal and specific documentation.

Selling an easement instead of donating it

Some programs pay for easements. The USDA Natural Resources Conservation Service's Agricultural Conservation Easement Program helps fund purchases of easements on working farmland and wetlands, often in partnership with state programs and land trusts.

Effect on value and property taxes

Because development rights are removed, a conservation easement usually lowers the market value of the land. That reduction is what an appraiser measures for a tax deduction: the difference between the value before and after the easement is placed.

Local property tax treatment varies. Some states direct assessors to account for the easement's restrictions, which can lower the assessed value, and many rural parcels already qualify for agricultural use assessment regardless of an easement. Ask the county assessor how easement-restricted land is valued in your jurisdiction.

Estate planning is another reason owners choose conservation easements. A lower value can reduce estate tax exposure, and federal law contains a separate exclusion for certain land subject to a qualified conservation easement. These rules are technical and change, so owners typically work with a tax advisor and the land trust together.

Finally, think about the long run. The easement will outlast you and any buyer. Choose a holder with the resources to monitor and defend it, and make sure the reserved rights leave room for the way the next generation may want to use the land.

Buying land with a conservation easement

The easement will appear in the title commitment. Read the full recorded document, not a summary, and ask the holder for the baseline documentation report and the most recent monitoring report. Confirm that the house, barn or use you plan fits within the reserved rights.

Get the baseline report showing conditions at the time of the grant.
Ask the holder about any past violations or pending approvals.
Expect a lower price than comparable unrestricted land.
