Real Estate Tax Calc
What happened
On October 22, 2026, the United States Tax Court issued Lontrac Enterprises, LLC v. Commissioner, T.C. Memo. 2026-108, cutting a claimed conservation easement deduction from approximately $74.5 million to $500,000. Chief Judge Urda wrote the opinion.
The facts follow a pattern common to syndicated conservation easement (SCE) promotions. Investors contributed roughly $8.8 million to acquire partnership interests in Lontrac, which owned 288.8 acres of rural land in Tennessee. In December 2014 the partnership donated a perpetual conservation easement on the property to Foothills Land Conservancy. Offering materials had projected substantial federal and state tax benefits far exceeding the amount invested.
The taxpayer\'s appraiser valued the easement at $74.5 million by assuming the land\'s highest and best use was a commercial stone-quarrying operation. The court rejected that premise. Chief Judge Urda found the land\'s actual highest and best use was recreational and rural residential — a conclusion supported in part by the fact that the property had been listed for sale at roughly $2.96 million for approximately five years without attracting a buyer at that price.
The court also sustained a 40% gross valuation misstatement penalty under IRC § 6662(h). The 40% rate (versus the standard 20%) applies when the claimed value of donated property exceeds 200% of its correct value — a threshold cleared comfortably here given the $74.5 million claim against a $500,000 correct figure. Following the decision, the IRS issued a reminder about its continuing enforcement in conservation easement cases at IRS.gov. A detailed case summary is available from Current Federal Tax Developments.
Why it matters to real estate investors
Syndicated conservation easements have appeared on the IRS Dirty Dozen list of abusive tax schemes for several consecutive years. The IRS formally designated them as listed transactions in Notice 2017-10, requiring disclosure by both promoters and investors. Lontrac is one of many similar cases; the IRS and courts have prevailed in the overwhelming majority of them.
The pattern repeats: an inflated appraisal based on speculative development scenarios — mining, resort development, commercial subdivision — is rejected in favor of actual market evidence. The 40% gross valuation misstatement penalty is then sustained because the discrepancy between claimed and correct value typically exceeds the 200% threshold.
For investors who participated in an SCE deal, the risk has multiple layers: (1) full disallowance of the charitable deduction, (2) the 20% or 40% valuation-misstatement penalty on the resulting underpayment, (3) interest on the underpayment accruing from the original filing year, and (4) potential exposure under § 6700 for organizers and advisors who structured the deal. Even investors who were passive limited partners — not the promoter or appraiser — bear these risks because partnership deductions flow through to every partner\'s individual return.
The IRS has hundreds of SCE cases in its enforcement pipeline, and investors who relied on 4:1 or higher projected write-off ratios relative to their cash investment have found courts largely unsympathetic.
How a legitimate conservation easement deduction is supposed to work
It helps to understand the genuine rule the abusive deals distort. Under IRC § 170(h), a landowner who permanently gives up certain development rights by granting a qualified conservation contribution can claim a charitable deduction. Three elements must all be present: (1) a qualified real property interest — typically a perpetual restriction on the use of the land, i.e. the easement itself; (2) a gift to a qualified organization, such as a governmental unit or a land trust that is a § 501(c)(3) with the commitment and resources to enforce the restriction; and (3) a protection granted exclusively for conservation purposes — outdoor recreation, protection of a natural habitat, preservation of open space, or preservation of a historically important land area or certified historic structure.
Two words do most of the work: perpetual and exclusively. The restriction, and the conservation purpose behind it, must be protected forever. A large share of the deductions the courts have thrown out failed not on valuation but on technical perpetuity defects — most famously the proceeds regulation at Reg. § 1.170A-14(g)(6), which governs how sale proceeds are divided if a court ever extinguishes the easement. If the deed lets the donor claw back the value of post-donation improvements, the IRS argues the conservation purpose is not protected in perpetuity.
On the paperwork side, the donor must obtain a qualified appraisal from a qualified appraiser and attach Form 8283 (Noncash Charitable Contributions), Section B, to the return. When the claimed deduction for donated property exceeds $500,000, the qualified appraisal itself must be attached under § 170(f)(11)(D). None of these requirements are controversial when a real landowner donates a real easement; the problems arise when the structure is built to manufacture a deduction many times the cash anyone put in.
The before-and-after valuation method — and the gap in Lontrac
Easements are valued under the before-and-after method in Reg. § 1.170A-14(h)(3): the fair market value of the property immediately before the easement, minus its fair market value immediately after. The ‘before’ figure rests on the land's highest and best use, and the courts apply a demanding four-part test — the proposed use must be legally permissible, physically possible, financially feasible, and the most profitable, each supported by real market evidence rather than a consultant's hypothetical.
Walk through the Lontrac numbers with that framework. Investors put roughly $8.8 million into the partnership. The clearest piece of market evidence was that the 288.8-acre tract had sat listed for sale near $2.96 million for about five years with no buyer — strong real-world proof that the land was worth a few million dollars, not tens of millions. On those facts a ‘before’ value of roughly $3 million and an easement value around $500,000 is defensible. The taxpayer's appraiser instead assumed the highest and best use was a commercial stone quarry, pushing the ‘before’ value to about $75 million and the deduction to $74.5 million — roughly 8.5 times the cash invested.
The court rejected the quarry premise because there was no market evidence that anyone would actually operate — or pay quarry prices for — this particular parcel. That is the recurring fault line in these cases: a deduction far larger than what a willing buyer would ever pay for the underlying land signals an appraisal built backward from a target tax benefit. When the speculative use collapses, the inflated value collapses with it, and only the modest real easement value survives.
The 2.5x basis limit that reshaped partnership easements
Lontrac's donation happened in 2014, but anyone looking at a conservation easement deal today runs into a rule that did not exist then. The SECURE 2.0 Act, enacted December 29, 2022, added IRC § 170(h)(7). For a qualified conservation contribution made by a partnership, S corporation, or other pass-through entity, no deduction is allowed to the extent the contribution exceeds 2.5 times the sum of each partner's or shareholder's relevant basis in the entity. It applies to contributions made after December 29, 2022.
The math is the point. A partnership whose partners have, say, $8.8 million of relevant basis can now support at most about $22 million of easement deduction — not $74.5 million. The provision was written specifically to break the inflated write-off ratios that defined syndicated deals, and it does so mechanically, before any appraisal fight even begins. A promotion advertising a deduction that is five, eight, or ten times invested capital generally cannot clear this limit at all under current law.
There are narrow statutory exceptions — among them certain contributions by family partnerships, contributions where the entity has held the property for more than three years, and certain donations preserving a certified historic structure. The exact contours are technical and fact-specific, so confirm whether any exception applies with independent counsel rather than relying on a promoter's summary.
The penalty stack: what a disallowed easement actually costs
Full disallowance of the deduction is only the first layer of exposure. The valuation-misstatement penalties under § 6662 escalate with the size of the overstatement: a 20% substantial valuation misstatement penalty applies when the claimed value is at least 150% of the correct value (§ 6662(e)), rising to a 40% gross valuation misstatement penalty when the claimed value is 200% or more of the correct value (§ 6662(h)) — the rate the court sustained in Lontrac. On top of that runs interest on the underpayment from the original due date of the return, which in these multi-year cases often rivals the tax itself.
A simplified, illustrative example shows the leverage working against the investor. Suppose you contributed $100,000 in cash and received a $400,000 flow-through deduction — a 4-to-1 ratio. In the 37% bracket, that deduction reduced your federal tax by about $148,000. If the deduction is fully disallowed, you owe that $148,000 back, plus a 40% gross valuation misstatement penalty of about $59,200 on the underpayment, plus interest accruing from the original filing date. That is more than $207,000 of federal exposure, before state tax and years of compounding interest, on a $100,000 investment — a net loss even though the deal was sold as a profit.
The exposure is not limited to investors. Promoters and appraisers who structure or substantially overvalue these transactions face their own penalties under § 6700 (promoting abusive tax shelters) and § 6694 (understatement by a return preparer), and appraisers can be penalized under § 6695A. Because the deductions flow through a partnership, every partner — however passive — shares the investor-side consequences.
Listed-transaction status and the disclosure trap
Syndicated conservation easements are not merely risky — many are listed transactions, a category of reportable transaction the IRS has flagged as potentially abusive. The agency first described them in Notice 2017-10. In Green Valley Investors, LLC v. Commissioner (2022), the Tax Court held that Notice 2017-10 was invalid because the IRS issued it without the notice-and-comment rulemaking the Administrative Procedure Act requires. The IRS responded by finalizing regulations in 2024 (Reg. § 1.6011-9) that re-identify substantially similar deals as listed transactions through proper rulemaking.
Listing carries hard disclosure duties. Participants must file Form 8886 (Reportable Transaction Disclosure Statement) with their return and with the IRS Office of Tax Shelter Analysis, and material advisors must file Form 8918 and keep investor lists under § 6112. Two consequences bite hardest: failing to disclose a listed transaction triggers a stand-alone penalty under § 6707A, and under § 6501(c)(10) the statute of limitations stays open until one year after the required disclosure is finally made — so an undisclosed deal can be examined and assessed long after the usual three-year window would have closed.
Red flags and common mistakes
Most of the warning signs are visible before anyone signs. The tax benefit is advertised as the main return — a projected write-off that is a large multiple (3:1, 4:1, or more) of the cash you put in — rather than genuine conservation. The appraisal rests on a speculative highest and best use (a quarry, mine, resort, or dense subdivision) with no buyer, permit, or operator actually in hand. The land was acquired shortly before the donation at a price far below the appraised ‘before’ value, and you are pressed to commit quickly near year-end.
The common mistake is treating a promoter's appraisal and legal opinion as independent assurance. They are not: the appraiser and advisor are typically paid by the deal and share exposure if it unwinds. Relying on them is also unlikely to establish the reasonable-cause, good-faith defense to penalties, because courts expect a taxpayer claiming a very large benefit to seek genuinely independent advice. None of this means conservation easements are off-limits — a real landowner who donates a real easement on property they intend to keep, with a market-supported appraisal and a clean deed, claims a legitimate deduction every year. The abuse is the inflated-appraisal, deduction-as-product structure, not conservation itself.
What to do
If you have already participated in a syndicated conservation easement and claimed a deduction, consult an independent tax attorney (separate from the advisor who promoted the deal) about statute-of-limitations exposure, disclosure obligations, and any available settlement options. The IRS has periodically offered settlement initiatives for SCE participants; specific terms and availability change, so verify current options with qualified counsel.
If you are evaluating an investment that advertises conservation easement deductions as the primary return driver — particularly where the projected write-off is several times your cash investment — exercise extreme caution. Legitimate charitable deductions for conservation easements exist, but courts have consistently rejected structures where the primary purpose is tax benefit rather than genuine conservation.
If you are looking for legally sound depreciation-based tax strategies for investment real estate, the landscape under current law is favorable without the legal risk of SCE promotions. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025 (per IRS Notice 2026-11), and a cost segregation study can identify the building components eligible for that immediate expensing. These strategies are governed by clear IRS rules and do not carry the speculative-appraisal and listed-transaction risk that defines SCE promotions.

Frequently asked questions
What is a syndicated conservation easement and why does the IRS challenge them?
A syndicated conservation easement (SCE) is a transaction in which investors buy interests in a partnership that then donates a permanent restriction on land use to a land trust. The partnership claims a large charitable contribution deduction based on an appraisal, and that deduction flows through to partners. The IRS challenges them because appraisals in these deals routinely rely on speculative highest-and-best-use scenarios to inflate the claimed value far beyond market reality. The IRS designated SCEs as listed transactions in Notice 2017-10, requiring mandatory disclosure by promoters and participants.
Does the Lontrac ruling affect investors in other conservation easement deals?
The decision is binding only on Lontrac\'s partners, but it reinforces the pattern courts have applied across many similar cases: speculative highest-and-best-use appraisals are rejected in favor of realistic market value, and the 40% gross valuation misstatement penalty is regularly sustained when the claimed value is more than twice the correct value. Investors in other SCE deals face the same legal framework and substantially the same risks.
What is the 2.5x basis rule for partnership conservation easements?
Added by the SECURE 2.0 Act effective for contributions made after December 29, 2022, IRC § 170(h)(7) disallows a conservation easement deduction claimed by a partnership, S corporation, or other pass-through entity to the extent the contribution exceeds 2.5 times the sum of each partner's or shareholder's relevant basis in the entity. It directly caps the inflated write-off ratios that defined syndicated deals, with narrow exceptions for certain family partnerships, property held more than three years, and certain certified historic structures. Confirm whether any exception applies with independent counsel.
How is a conservation easement's value determined for tax purposes?
Easements are valued under the before-and-after method of Reg. § 1.170A-14(h)(3): the property's fair market value immediately before the easement minus its fair market value after. The before value turns on the land's highest and best use, which must be legally permissible, physically possible, financially feasible, and the most profitable, each supported by real market evidence rather than a hypothetical. The donor must obtain a qualified appraisal and file Form 8283, Section B; when the claimed deduction exceeds $500,000, the appraisal itself must be attached to the return.
What penalties apply if the IRS disallows a conservation easement deduction?
Beyond losing the deduction and owing back the tax it saved, a taxpayer typically faces a valuation-misstatement penalty under IRC § 6662 — 20% when the claimed value is at least 150% of the correct value, or 40% when it is 200% or more — plus interest on the underpayment from the original due date. Failing to disclose a listed transaction adds a penalty under § 6707A, and promoters, advisors, and appraisers face separate exposure under §§ 6700, 6694, and 6695A.
Are all conservation easement donations considered abusive?
No. A genuine conservation easement — where a landowner permanently restricts development on property they intend to keep, donates it to a qualified land trust, and supports the deduction with a market-based appraisal and a properly drafted deed — is a legitimate charitable contribution under IRC § 170(h). The IRS and courts target syndicated promotions that use speculative appraisals to generate a deduction many times the cash invested, not conservation donations themselves.
