Background: What Are Conservation Easements & the Problem

A conservation easement allows a property owner to give up certain building or land-use rights—like preventing development—in exchange for a charitable deduction. But recent decades have seen promoter-led syndicated easement deals that use inflated appraisals to generate big deductions. Courts have rejected many, letting only around 6% of the claimed deductions.(irs.gov)

What’s the IRS Settlement Offer?

Announced May 13, 2026, the IRS launched a time-limited settlement opportunity (IR-2026-65) for conservation or historic preservation easement cases.(irs.gov) Key features:

  • Partnerships can settle without paying upfront; liability is collected later.
  • Charitable deduction not allowed; instead, the IRS allows an “other deduction” roughly equal to out-of-pocket costs.
  • Gross valuation misstatement penalty: 10% during the first 90 days after each taxpayer gets a settlement letter; rises to 20% in the subsequent 45-day window. After that, full penalties (~40%) if going to court.(irs.gov)

Who Qualifies & Who Doesn’t

Eligible:

  • Syndicated partnerships in easement cases not tried or on appeal yet.
  • Cases where prior offers expired or were rejected.
  • Some that weren’t eligible before.
    Not eligible:
  • Cases already tried and awaiting opinions.
  • Cases on appeal.
  • Ones set for immediate trial (within 30 days of notice).
  • Cases already settled or tied to other decisions.
  • Nexus with test cases still unsettled.(irs.gov)

Risks vs Rewards: Evaluate with Context

BenefitRisk
Avoid large reductions court may impose (typically disallowing ~94% of claimed deductions).Still substantial penalties and interest accrue even under settlement.
Less legal cost and faster resolution rather than drawn-out litigation.No charitable deduction–you won’t benefit from favorable tax treatment; you get only costs.
Certainty and closing the case on known terms.If you decline, worst outcomes likely: deduction ~5-7%, penalty ~40%.

Examples & Timing

  • A partnership claims a $1,000,000 deduction. Under settlement, your “other deduction” might be around $200,000 (just the actual costs). With 10% penalty during the 90-day window, you’d owe penalty on underpayment portion. After 135 days, penalties are much higher.
  • If IRS sends settlement letters on May 15, you have until ~August 13 (90 days) to accept the most favorable terms. After that, terms worsen. Timely decision matters.

What You Should Do Now

  1. Check status: Determine if your easement case qualifies for settlement—file status, trial set, appeal status.
  2. Act quickly after letter: 90-day window has large advantages—lower penalties.
  3. Consult experts: Appraisers, tax litigators or attorneys with experience in conservation easement cases—uncertainties in valuation and legal precedent remain large.
  4. Maintain documentation: Appraisals, out-of-pocket costs, legal fees—critical for computing “other deductions.”

Bottom line: If you’re involved in a qualifying easement dispute, this settlement opportunity offers a safer alternative to steep court penalties—but only if you meet eligibility criteria and act within strict deadlines.
