Conservation Easements: Real Deduction, Real IRS Scrutiny
How giving up development rights on land creates a charitable deduction, why syndicated versions became one of the most litigated tax shelters, and the 2022 limits that now apply.

A conservation easement is a permanent restriction on land — surrendering development rights — donated to a qualified land trust or government. The donor deducts the value of the rights given up, measured before and after the restriction. For a landowner who truly means to preserve the land the deduction is real; syndicated versions are treated as abusive shelters.

How does the deduction work?
| Element | Rule |
|---|---|
| Qualified property | Real property, including farmland, timberland, open space, historic structures |
| Recipient | A qualified organization — a land trust or government unit — that will enforce the restriction |
| Conservation purpose | Habitat, open space, outdoor recreation, or historic preservation, with public benefit |
| Perpetuity | The restriction must last forever; mortgage holders must subordinate; the deed must meet technical requirements that have defeated many deductions |
| Value | Appraised difference between the land's highest-and-best-use value before and its restricted value after |
| Substantiation | Qualified appraisal, Form 8283 signed by the appraiser and donee, baseline documentation of the property's condition |
| Income limit | 50 percent of adjusted gross income (100 percent for qualifying farmers and ranchers), with a 15-year carryforward |
What went wrong with syndicated easements?
Promoters bought land, sold partnership interests to investors, obtained appraisals valuing the land at many times the purchase price (based on hypothetical development), and donated easements producing deductions of four or five dollars for every dollar invested. The IRS designated these arrangements listed transactions in Notice 2017-10 (issued December 2016) — reissued as final regulations in October 2024 after courts set the notice aside on procedural grounds — litigated hundreds of cases, and generally won on valuation and on technical deed defects. Congress responded in the SECURE 2.0 Act of 2022: for contributions after December 29, 2022, a partnership's or other pass-through entity's easement is not a qualified conservation contribution if it exceeds 2.5 times the sum of each partner's relevant basis (basis allocable to the property), unless it is made at least three years after the entity acquired the land and every partner acquired its interest, the entity is a family partnership, or the easement preserves a certified historic structure. Promoters have faced criminal charges.
What does a legitimate donation look like?
Land the owner has held for years, an appraisal at a defensible value by an appraiser with no stake in the outcome, a land trust that actually monitors and enforces, and a conservation purpose the public can see. A deduction that reflects the value actually given up — a fraction of the land's value, not a multiple of its cost.
What are the audit risks even for a real donation?
Appraisal challenges, deed language that fails the perpetuity test (such as allowing proceeds on extinguishment to be allocated improperly), missing baseline documentation, and donee acknowledgment defects. These are curable with care before the deed is recorded, not after.
Frequently asked questions
Can an easement on a business's property qualify?
Yes, if the property and purpose qualify; the business deducts through its owners if a pass-through.
Does the deduction reduce the land's basis?
Yes, proportionally, which affects gain on a later sale of the restricted land.
Does a historic facade easement still qualify?
Yes, on certified historic structures, though the IRS examines valuations closely because local preservation rules often already restrict the facade.
What if the land trust later releases the easement?
Perpetuity is a requirement at donation; the deed must provide that extinguishment can occur only by court order with proceeds shared with the donee.

The IRS explains: “A legitimate conservation easement often reflects long-standing ownership, an accurate and property-specific valuation, and compliance with the rules governing qualified conservation contributions.” — Internal Revenue Service, Conservation easements, https://www.irs.gov/charities-non-profits/conservation-easements
The statute provides: “A contribution by a partnership (whether directly or as a distributive share of a contribution of another partnership) shall not be treated as a qualified conservation contribution for purposes of this section if the amount of such contribution exceeds 2.5 times the sum of each partner’s relevant basis in such partnership.” — Legal Information Institute, Cornell Law School, 26 U.S. Code § 170 - Charitable, etc., contributions and gifts, https://www.law.cornell.edu/uscode/text/26/170
