The Conservation Easement Tax Deduction: How Trump Wrote Off $21 Million on Land He Still Owns.

A real estate investor sitting on a few hundred acres of undeveloped land near a growing town has a quiet problem: the land is worth far more than they paid, and selling it triggers a large capital gain. One option that keeps coming up is the conservation easement tax deduction. You keep the land, you give up the right to develop it, and you claim a charitable deduction for the value of what you gave away. Done right, it is one of the most powerful deductions in the code. Done wrong, it is one of the most heavily litigated.

The most famous user of this deduction is also the most polarizing. In December 2015, Donald Trump donated a conservation easement on part of his Seven Springs estate in Westchester County, New York, and claimed a $21.1 million charitable deduction. He had already used the same move in 2014 at his Los Angeles golf club, giving up the right to build 16 homes on a hillside driving range and claiming a roughly $25 million deduction while continuing to use the land as a range. Both deductions later became a focus of New York Attorney General Letitia James's civil fraud case. Reuters documented the golf-range deal in detail. The strategy itself is legal. The fight is almost always about the number.

A conservation easement is a permanent restriction you place on your own land, recorded against the deed, that limits how the property can be developed. You donate that restriction to a qualified organization, usually a land trust or a government body, and under IRC §170(h) the donation counts as a qualified conservation contribution. You keep title to the land and you keep using it within the limits of the easement. What you give away is the development right, and the deduction equals the drop in the land's value caused by giving it up.

Three conditions in §170(h) make or break it. The interest has to be a qualified real property interest, the recipient has to be a qualified organization, and the easement has to serve a genuine conservation purpose that is protected in perpetuity. Perpetuity is the one that sinks most deductions. If the easement deed lets the restriction be lifted, or fails to guarantee the land trust its proportionate share of proceeds when the easement is ever extinguished, the IRS disallows the entire deduction, not just part of it. The Tax Court has voided multimillion-dollar deductions over a single defective clause.

The deduction is the difference between the land's value at its highest and best use and its value once the easement restricts it. That gap is an appraisal opinion, and appraisal opinions can be stretched. Trump's Seven Springs appraisal from Cushman & Wakefield valued the estate around $56.5 million, while local assessors pegged it near $20 million. At the golf club, Trump valued the driving range parcel at about $900,000 in a 2013 property tax appeal, then signed an easement a year later supporting a roughly $25 million deduction. Inconsistent numbers like these are exactly what the IRS and state regulators look for.

This is why the substantiation rules are strict. For any noncash gift over $5,000, IRC §170(f)(11) requires a qualified appraisal by a qualified appraiser, and you attach Form 8283 to the return. For a conservation easement the appraisal must establish the before-and-after fair market value, and it has to be dated no earlier than 60 days before the donation. A thin or aggressive appraisal is the single most common reason these deductions collapse on audit. The same valuation discipline shows up in other niche deductions, like the Augusta rule for renting your home to your business, where the defensible number is the whole game.

The deduction earned its bad reputation through syndicated deals. Promoters would buy land, obtain an aggressive appraisal claiming the development value was many times the purchase price, donate an easement, and pass an inflated deduction through a partnership to investors who had bought in days earlier. The IRS labeled these syndicated conservation easement transactions as listed transactions in Notice 2017-10, then the Tax Court struck that notice down in Green Valley Investors, LLC v. Commissioner, 159 T.C. No. 5 (2022), for skipping the required notice-and-comment process. Treasury came back with final regulations in October 2024 (T.D. 10007) that re-listed the deals through proper rulemaking, so participants and promoters must report them or face penalties.

Congress acted too. The Charitable Conservation Easement Program Integrity Act, signed December 29, 2022, added IRC §170(h)(7): a partnership or S corporation gets no deduction at all if the easement value exceeds 2.5 times the partners' combined relevant basis, for contributions made after December 29, 2022. There are narrow carve-outs, including a three-year holding period and family-owned pass-throughs. The 2.5x rule does not touch an individual donating an easement on land they have owned for years, which is the legitimate version of what Trump did. It is aimed squarely at the syndicated shelters.

One more change lands in 2026. The One Big Beautiful Bill Act added a 0.5% of AGI floor on itemized charitable deductions and caps the benefit at 35% for top-bracket donors, both effective for the 2026 tax year. A conservation easement deduction still works, but a high earner now loses the first half-percent of AGI in deductions and values the rest at 35 cents on the dollar rather than 37. For a household weighing whether to shelter land or sell it, that shifts the math, the same way the other strategies high W-2 earners use to cut their tax bill have to be re-run under the new rules.
