Conservation Easement Deductions: What Is Legitimate and What the IRS Attacks

A conservation easement donation is a legitimate charitable deduction under IRC Section 170(h) when a landowner permanently restricts development on their own property and donates that restriction to a qualified organization. A syndicated conservation easement, where investors buy into a partnership that donates an inflated easement and passes back a deduction several times their investment, is a different thing entirely. It is a listed transaction, subject to a statutory disallowance rule, and the IRS has prevailed in the overwhelming majority of litigated cases.

The Legitimate Version

Section 170(h) allows a deduction for a qualified conservation contribution, which requires three elements:

1. A qualified real property interest, typically a perpetual restriction on the use of the land
2. A qualified organization, generally a land trust or government unit with the commitment and resources to enforce the restriction
3. A conservation purpose, meaning public recreation or education, protection of a natural habitat, preservation of open space with public benefit, or preservation of a historically important structure

A farmer who permanently gives up development rights on land that will stay a farm, and takes a deduction reflecting the honest difference in value, is doing exactly what Congress intended. Deduction limits are favorable: generally 50 percent of AGI with a 15 year carryforward, and 100 percent of AGI for qualified farmers and ranchers.

The Version That Draws Enforcement

In a syndicated deal, a promoter assembles investors into a partnership that acquires land, obtains an appraisal asserting a very high value based on a hypothetical development that was never going to happen, donates an easement, and allocates a charitable deduction often four to nine times what each investor contributed.

The IRS designated these as listed transactions in Notice 2017-10, placed them on the annual Dirty Dozen list repeatedly, and has litigated aggressively. Courts have overwhelmingly sided with the government, frequently on both valuation and technical defects in the easement deed itself.

The Statutory Rule That Ended Most of These

The SECURE 2.0 Act of 2022 added Section 170(h)(7), which disallows a partnership level conservation easement deduction that exceeds 2.5 times the sum of the partners' adjusted bases in the partnership. The rule applies to contributions made after December 29, 2022.

This removed the economics from the syndicated model. A deal promising a 4.5 to 1 deduction cannot deliver it. Narrow exceptions exist for family partnerships, property held three years or more, and certified historic structures, and those exceptions are where remaining promoter activity has migrated.

Penalty Exposure

Penalty	Amount	When it applies
Accuracy related, substantial valuation misstatement	20% of underpayment	Claimed value 150% or more of correct value
Gross valuation misstatement	40% of underpayment	Claimed value 200% or more of correct value
Reportable transaction understatement	20% or 30%	Listed transaction not properly disclosed
Failure to disclose on Form 8886	Up to $100,000 individual	Participation in a listed transaction

Add interest running from the original due date, plus the professional cost of a multi year examination and possible Tax Court litigation. The reasonable cause defense based on reliance on an appraisal has been rejected repeatedly where the appraisal was procured by the promoter.

Substantiation Requirements That Fail Deals on Technicalities

Many easement cases are lost without ever reaching valuation, because the paperwork was defective:

• Qualified appraisal by a qualified appraiser, meeting every element of the regulations
• Form 8283 Section B, signed by both appraiser and donee
• Contemporaneous written acknowledgment from the donee, obtained before the return is filed
• Cost basis disclosure on Form 8283, an omission courts have treated as fatal
• A perpetuity compliant deed, particularly the extinguishment clause governing what the donee receives if the easement is ever terminated. Improper proceeds formulas have sunk many otherwise defensible donations.
• Baseline documentation establishing the property's condition at the time of donation
• Form 8886 if the transaction is listed or substantially similar

How to Tell the Two Apart

Legitimate donation	Warning signs
You already owned the land, often for years	Land acquired shortly before donation
Deduction roughly matches real value given up	Deduction is a multiple of your cash investment
You chose the appraiser	Promoter supplied the appraiser
Conservation is the actual objective	Marketed by projected tax savings ratio
Established land trust with stewardship funding	Land trust formed or funded by the promoter
Valuation based on realistic highest and best use	Valuation assumes development that was never feasible

If You Already Participated

Do not simply wait. Options include filing Form 8886 disclosure if it was not filed, amending to remove the deduction to limit penalty exposure, and getting independent representation rather than relying on counsel selected by the promoter, whose interests diverge from yours once an examination begins.

Better Tools for the Same Objective

If the goal is a large deduction against high income, there are strategies with far better risk adjusted outcomes:

• Cost segregation paired with bonus depreciation
• Defined benefit and cash balance plans
• Donor advised funds and appreciated securities gifts
• PTET elections for pass through owners
• Charitable remainder trusts where philanthropy is genuinely intended

None of these promise a four to one deduction, because nothing legitimate does.
