Conservation easements sit at the intersection of environmental policy and tax planning. When a landowner donates a qualified conservation easement, they give up certain property rights (typically the right to develop the land) in exchange for a charitable deduction that can offset income for up to 16 years (the year of donation plus 15 carryforward years). Under IRC 170(h), the contribution must be a “qualified conservation contribution,” which means it must be a restriction on the use of real property granted in perpetuity to a qualified organization exclusively for one of four conservation purposes. The deduction is based on the difference between the property’s before-easement and after-easement appraised values, which means the landowner retains ownership of the property and can continue to use it for any purpose not restricted by the easement (farming, ranching, timber harvesting, personal use, and often limited residential use are typically preserved). For landowners with significant acreage, the deduction can be worth millions of dollars. However, the IRS has been challenging aggressive easement valuations (where the claimed deduction far exceeds the actual reduction in property value), particularly in the context of syndicated easement transactions where investors buy into partnerships that hold property and claim inflated deductions.

✓Key takeaway

Conservation easement deduction rules:

Rule	Details
Deduction amount	FMV before easement minus FMV after easement
AGI limit (general)	50% of AGI (30% for appreciated capital gain property donated to a private foundation)
AGI limit (qualified farmers/ranchers)	100% of AGI
Carryforward	15 years (16 total including the donation year)
Must be perpetual	The restriction must last forever
Qualified organization	Land trust, government entity, or other IRC 501(c)(3) organization with a conservation purpose
Qualified appraisal required	By a qualified appraiser, attached to the return
Form 8283	Noncash charitable contribution form; must be filed with the return

Four qualified conservation purposes (IRC 170(h)(4)):

Purpose	Examples
Outdoor recreation or education for the general public	Public hiking, fishing, hunting access
Protection of natural habitats	Wetlands, forests, wildlife corridors
Preservation of open space (scenic or pursuant to government policy)	Farmland preservation, viewshed protection, urban greenbelts
Preservation of historically important land or structures	Battlefield preservation, historic buildings, archaeological sites

How does a conservation easement deduction work?

Hypothetical example

Round numbers. A farmer owns 500 acres of farmland with a combined appraised value of $3,000,000. The farmer places a conservation easement on the property, permanently restricting development while allowing continued agricultural use.

Easement valuation:

Item	Amount
Before-easement FMV (highest and best use: development potential)	$3,000,000
After-easement FMV (restricted to agricultural use only)	$1,500,000
Easement value (charitable deduction)	$1,500,000

The farmer retains full ownership and can continue farming. The restriction only eliminates the development potential.

Deduction usage (qualified farmer, 100% AGI limit):

Year	AGI	Deduction Used	Remaining Carryforward
Year 1	$200,000	$200,000 (100% of AGI)	$1,300,000
Year 2	$220,000	$220,000	$1,080,000
Year 3	$180,000	$180,000	$900,000
Year 4	$210,000	$210,000	$690,000
Year 5	$230,000	$230,000	$460,000
Year 6	$200,000	$200,000	$260,000
Year 7	$190,000	$190,000	$70,000
Year 8	$200,000	$70,000	$0
Total deducted		$1,500,000
Total tax savings (average 30% effective rate)		$450,000

For a non-farmer (50% AGI limit):

Year	AGI	Deduction Limit (50% of AGI)	Deduction Used	Remaining
Year 1	$400,000	$200,000	$200,000	$1,300,000
Year 2	$400,000	$200,000	$200,000	$1,100,000
Year 3	$400,000	$200,000	$200,000	$900,000
…
Year 8 (15-year carryforward ends after Year 16)

With a 50% AGI limit, a taxpayer with $400,000 AGI uses $200,000/year, needing 7.5 years to fully deduct $1,500,000.

IRS crackdown: Syndicated conservation easements

The IRS has designated syndicated conservation easements as listed transactions (Notice 2017-10). These are arrangements where:

Feature	Details
Partnership purchases property	Often at a price significantly below the appraised easement value
Investors buy partnership interests	Primarily for the tax deduction, not the property
Inflated appraisal	The easement value is appraised at 2.5x or more of the investors’ total investment
Result	Investors claim deductions far exceeding their economic investment
IRS position	These are abusive tax shelters; deductions are disallowed and 40% penalties (IRC 6662A) are applied

Example of a syndicated easement:

Item	Amount
Partnership purchases property for $500,000
Easement appraised at $4,000,000
10 investors each invest $50,000	Total invested: $500,000
Each investor claims 1/10 of the $4,000,000 deduction	$400,000 deduction each
Investor’s tax savings (37% x $400,000)	$148,000
Investor’s cash investment	$50,000
”Return” on investment	296% (in tax savings alone)

The IRS has won numerous cases challenging these arrangements, including the Sixth Circuit’s decision in Hewitt v. Commissioner and the Tax Court’s decisions in multiple syndicated easement cases. Penalties include:

Penalty	Amount
40% gross valuation misstatement penalty (IRC 6662(h))	40% of the tax underpayment
Listed transaction penalty (IRC 6662A)	30% of the understatement (75% if not disclosed)
Failure to report listed transaction (Form 8886)	$10,000 per failure ($200,000 if related to a listed transaction involving a tax shelter)
Promoter penalties (IRC 6700)	Against the promoters organizing the syndication

Legitimate conservation easements (how to protect the deduction):

Best Practice	Why
Use a qualified, independent appraiser	Appraisal must be defensible; avoid appraisers who work for the easement promoter
Ensure the conservation purpose is genuine	The land must have real conservation value (not just a tax-motivated transaction)
Work with an established land trust	National Land Trust Alliance accredited organizations have the strongest track record
Baseline documentation report	Detailed report documenting the property’s condition at the time of the easement
Keep the deduction proportional to the actual restriction	A deduction of 2.5x+ the cost basis is a red flag
File Form 8283 with a qualified appraisal	Required for all noncash charitable contributions over $5,000
Disclose the transaction	If the deduction exceeds 2.5x the investment, disclosure as a listed transaction may be required
