In 2016, a partnership claimed a $180.2 million tax deduction after placing an easement on 236 Mississippi acres; the US Tax Court valued the deduction at about $2.2 million

The US Tax Court dramatically reduced a $180.2 million charitable contribution deduction claimed by a partnership after it placed a conservation easement on 236 acres of land in Mississippi.In Hancock County Land Acquisitions, LLC v. Commissioner, T.C. Memo. 2026-28, the court determined that the conservation easement was worth approximately $2.18 million, rather than the $180.177 million claimed on the partnership’s 2016 tax return. The analysis was detailed in a March 26, 2026 report by Ed Zollars, CPA, on Current Federal Tax Developments.The case involved a syndicated conservation easement (SCE) transaction involving undeveloped land in Hancock County, Mississippi, within a buffer zone surrounding the John C. Stennis Space Center.The court also disallowed most of the partnership's claimed business expenses and upheld penalties related to the overvaluation and other deductions.How the Mississippi land deal was structuredThe 236-acre property was carved out of a larger 1,698-acre tract that had been bought and sold several times between 2003 and 2013. Those transactions established historical prices ranging from $895 to $7,479 per acre.By March 2015, the undeveloped 236-acre property was held by WMAH, which was solely owned by Shale Support Holdings, LLC.In early 2016, Shale Support retained Webb Creek Capital Management Group, LLC, a promoter of syndicated conservation easement transactions, to structure the deal.The transaction followed a common SCE structure. Argive was established as the investment company, while Hancock County Land Acquisitions, LLC (HCLA) served as the property company.Argive raised $23,374,575 from investors and used $18,247,575 to acquire a 97% interest in HCLA. Investors were offered a promised charitable contribution tax deduction of $7.477 for every dollar invested.On August 2, 2016, HCLA granted a conservation easement over the property to Atlantic Coast Conservancy.Partnership claimed $180.2 million deductionTo determine the value of the easement, an appraiser used a discounted cash flow model based on a hypothetical frac sand mining operation.Using that appraisal, HCLA claimed a $180,177,000 charitable contribution deduction on its 2016 Form 1065.The partnership also claimed $6,128,493 in ordinary business expense deductions, including management fees, legal and professional expenses and a roughly $1.68 million tax-loss insurance premium.The IRS disallowed the deductions and asserted both a 40% gross valuation misstatement penalty and a 20% accuracy-related penalty.Taxpayer abandoned its original $180 million valuationAt trial, the taxpayer changed its approach and did not attempt to defend the original $180 million appraisal.Judge Lauber noted that Argive, acting as the tax matters partner, "did not seek to defend that outlandish valuation at trial."Instead, the taxpayer argued that the amount investors paid to acquire their interest in HCLA should be used to determine the property's value before the easement.Argive contended that the $18.2 million investment transaction demonstrated a pre-easement fair market value of at least $18.63 million, or $78,962 per acre.The court rejected that argument.Court says investors were buying tax deductionsUnder federal tax rules, fair market value is generally based on what a willing buyer would pay a willing seller, with neither party being forced to buy or sell and both having reasonable knowledge of the relevant facts.For conservation easements, the value is generally determined using the before-and-after approach: the property's fair market value before the easement, minus its value after the easement.The court found that the investor transaction did not represent an arm's-length purchase of the underlying land.Judge Lauber wrote, "The investors were not purchasing land; in substance, they were purchasing tax deductions."The court also found that Webb Creek and Shale Support were not negotiating the property's market value with investors. Instead, the transaction involved dividing the approximately $24 million raised from investors.As a result, the court did not treat the partnership interest purchase price as evidence of the property's fair market value.Frac sand mining was not financially feasibleThe court also rejected the taxpayer's proposed highest and best use of the property.For valuation purposes, the highest and best use must be legally permissible, physically possible, financially feasible and maximally productive.The court found that frac sand mining did not meet the financial feasibility requirement in August 2016.The market for sand and gravel was depressed, oil prices had fallen and the number of active drilling rigs had declined. The court also considered the absence of proven profitability from the property's predecessor and the decision to pursue a conservation easement rather than mine the property.Instead, the court determined that the property could be used for recreation, timber harvesting, agriculture and possible future development as an exploratory mineral property.Comparable sales point to a much lower valueRather than relying on the discounted cash flow model, the court relied heavily on comparable property sales.One important 2016 transaction involved a highly comparable 500-acre tract that sold for $8,000 per acre. Other nearby properties had sold for prices reaching $14,000 per acre.Based on the comparable sales and its own assessment of the evidence, the court determined that the 236-acre property's before-easement value was $10,000 per acre, or $2.36 million.The stipulated value after the easement was $177,000.That left HCLA with an allowable conservation easement deduction of $2.183 million.In other words, the court reduced the claimed $180.177 million deduction by more than $178 million.Court rejects $1.68 million tax insurance deductionThe court separately examined the partnership's business expense deductions.HCLA had claimed a $1,688,944 tax-risk insurance premium, arguing that the insurance protected the partnership against business risks.The court disagreed, finding that the policy primarily protected individual investors against the loss of anticipated tax benefits if the IRS disallowed the conservation easement deduction.The expense therefore was not an ordinary and necessary expense of HCLA's business and was not deductible under Section 162.The court also rejected most of the partnership's professional and consulting expenses because they were related to the syndication and promotion of partnership interests, making them nondeductible syndication expenses under Section 709.However, the court allowed a $25,000 appraisal fee, finding that the appraisal was required to substantiate the charitable contribution deduction.40% valuation penalty upheldThe court also upheld the 40% gross valuation misstatement penalty.The claimed easement value of $180.177 million was more than twice the correct value determined by the court. Federal tax law provides for the 40% penalty in cases involving such gross valuation misstatements.The court also rejected a reasonable-cause defense for the valuation penalty because the tax code does not permit such a defense for certain gross valuation misstatements involving charitable contribution property.A separate 20% accuracy-related penalty was upheld in connection with the disallowed Section 162 deductions.Tax preparer's involvement weakened reasonable-cause defenseThe taxpayer argued that it had reasonably relied on its return preparer.The court rejected that argument because the accountant was also an investor in the syndicated conservation easement transaction and had actively promoted the deal.That involvement meant the accountant did not have the independence and objectivity necessary for the taxpayer to establish reasonable reliance on professional advice.Another case involving syndicated conservation easementsThe Tax Court characterized the case as "a syndicated conservation easement (SCE) case with a familiar fact pattern."The transaction featured several elements seen in other conservation easement cases, including separate investment and property companies, a large tax deduction promised to investors and an aggressive appraisal based on a hypothetical development use.The court's treatment of the partnership interest purchase price also reinforces that an investor's contribution to an SCE structure does not necessarily establish the fair market value of the underlying real estate.Here, the court concluded that the transaction was driven primarily by the anticipated tax benefits rather than an arm's-length negotiation over the value of the 236-acre property.Final rulingThe US Tax Court ultimately determined that HCLA was entitled to a $2.183 million conservation easement deduction, compared with the $180.177 million deduction it originally claimed.The court also disallowed most of the partnership's claimed business expenses and upheld the 40% gross valuation misstatement penalty and 20% accuracy-related penalty.Catch the latest World News and Live updates.
