What a conservation easement is
A conservation easement is a voluntary legal agreement between a landowner and a qualified land trust or government entity under which the landowner permanently restricts certain uses of their property — typically development — in exchange for a charitable deduction. The landowner keeps title and can continue using the land, but has given up specific development rights permanently.
The deduction is the difference between the property's FMV before the easement (with development rights) and FMV after (without development rights), as determined by a qualified appraisal. Under IRC Section 170(h), the donation must meet specific requirements: the land trust must be a qualified organization, the restriction must be permanent, and the conservation purpose must qualify (preservation of natural habitat, scenic open space, historical structures, or public recreation).
How the deduction works
Conservation easement deductions can be substantial — often 30–100% or more of the land's pre-easement value, depending on the development potential being surrendered. The deduction is a charitable contribution on Schedule A, subject to AGI limitations: generally limited to 50% of AGI per year, with a 15-year carryforward for the excess (or up to 100% of AGI for qualified farmers and ranchers).
Example: A 100-acre parcel with $2 million in development value donates an easement. If FMV drops to $500,000 after the easement, the deduction is $1.5 million. At a 37% combined rate, the tax savings over the carryforward period could approach $550,000.
IRS scrutiny and syndicated easements
The IRS has placed syndicated conservation easements on its "dirty dozen" list of tax scams for several years. These are promoter-marketed transactions where investors purchase land partnerships primarily to claim inflated easement deductions, often 4:1 or higher ratios of deductions to investment. The IRS has disallowed many such transactions and imposed penalties.
Legitimate conservation easements — donations made for genuine conservation purposes on land you own, valued by a qualified independent appraisal — remain a valid tax strategy. The scrutiny is aimed at fabricated or inflated valuations. Get a reputable appraiser, use a recognized land trust, and work with a tax attorney experienced in conservation transactions.
Frequently asked questions
How much is a conservation easement deduction worth?
The deduction equals the reduction in FMV caused by the easement restriction, determined by a qualified appraisal. There is no fixed ratio — it depends entirely on the land's development potential.
What is a qualified land trust?
A nonprofit organization under IRC 501(c)(3) whose primary purpose is to preserve land for conservation. The National Land Trust Alliance has a database of accredited land trusts.
Are syndicated conservation easements legal?
Some promoter-marketed syndicated transactions have been declared listed transactions by the IRS and disallowed. Legitimate owner-donor easements remain valid but require rigorous documentation and defensible appraisals.
