IRS Offers New Settlement Window for Syndicated Conservation Easement Cases: What Investors Should Consider
The IRS has announced a new time-limited settlement opportunity for eligible partnerships involved in syndicated conservation easement and historic preservation easement disputes. For investors still involved in these cases, the offer deserves careful review.
The settlement terms are not generous in the ordinary sense. The IRS continues to disallow the claimed charitable contribution deduction and allows only an “other deduction” generally tied to the partnership’s approximate out-of-pocket costs. But compared with the government’s litigation position, the offer may materially reduce penalty exposure and provide a more predictable resolution.
For many investors, the practical question is no longer whether the IRS views these transactions as abusive. It does. The question is whether a particular partnership has meaningful litigation defenses that justify rejecting the offer and continuing the case.
The New IRS Settlement Offer
On May 13, 2026, the IRS announced a new settlement initiative for eligible taxpayers involved in conservation easement or historic preservation easement disputes. The IRS stated that prior settlement initiatives had resolved 405 cases, with 32% of offers accepted, but that more than 1,100 conservation easement cases remain pending, including approximately 740 docketed cases in Tax Court and 400 cases in examination.

For eligible partnerships, the IRS will issue individualized settlement correspondence. During the first 90 days after the settlement letter is issued, the general terms are:
No charitable contribution deduction is allowed.
An “other deduction” is allowed in an amount determined by the IRS, generally equal to the partnership’s approximate out-of-pocket costs.
A 10% gross valuation misstatement penalty applies.
Interest accrues as required by law.
The partnership is not required to pay at the moment it elects into the initiative.
Docketed cases are resolved by stipulated decision.
Non-docketed BBA cases are resolved by closing agreement or similar document.
No extension of the 90-day period is available.
After the initial 90-day window closes, eligible partnerships have an additional 45 days to settle on generally similar terms, except that the gross valuation misstatement penalty increases to 20%. After the total 135-day period expires, the IRS states that cases will be resolved before court decision only based on hazards of litigation, which generally means a charitable contribution deduction of approximately 5% to 7% of the claimed deduction and a 40% gross valuation misstatement penalty.
Why This Offer Matters
The IRS’s position is blunt. It states that, in recent litigation, the government has consistently prevailed, with the Tax Court allowing on average only 6% of the original claimed deduction and generally imposing a 40% gross valuation misstatement penalty, plus interest.
That litigation record is the main reason the offer deserves attention. The early settlement window preserves a deduction for approximate out-of-pocket costs and limits the valuation penalty to 10%. If the case proceeds and is lost, the investor may face a much larger tax adjustment, a 40% penalty, and interest running from the original due date of the return.
The settlement offer does not eliminate tax, penalty, or interest exposure. But it may reduce the downside compared with a full litigation loss.
A Simple Cost Comparison
Assume an investor contributed $100,000 to a syndicated conservation easement partnership and was allocated a $430,000 charitable contribution deduction.
Under the 10% settlement framework, the charitable deduction is disallowed, but the investor may effectively retain a deduction for approximate out-of-pocket cost. If the investor’s cost-based deduction is $100,000, the net disallowed deduction is $330,000. At a 37% marginal federal rate, that produces $122,100 of additional tax. A 10% penalty on that tax is $12,210. Before interest, the total is $134,310.
If the investor rejects the offer and loses in litigation, assume only 5% of the claimed $430,000 deduction is allowed. That leaves $408,500 of disallowed deduction. At a 37% federal rate, the tax is $151,145. A 40% penalty is $60,458. Before interest, the total is $211,603.
In that example, the litigation-loss outcome is approximately 57% more expensive before interest.
The actual comparison depends on the investor’s tax rate, claimed deduction, cash investment, year at issue, penalty exposure, state tax consequences, payment history, and whether the partnership has viable defenses. But the example illustrates why investors should not evaluate the settlement offer solely by comparing it to the original tax benefit claimed. The relevant comparison is often the settlement cost versus the probable cost of losing.
Litigation Risk Is Partnership-Specific
Not every syndicated conservation easement case is the same. Some partnerships may have stronger procedural defenses than others. Certain cases have resulted in taxpayer victories based on untimely partnership adjustments, penalty approval failures, or Administrative Procedure Act challenges to IRS listed-transaction guidance.
Those procedural victories matter. They may eliminate penalties or, in some cases, resolve the case entirely. But they are not the same as winning on the underlying valuation or technical easement merits.
The IRS has also moved to address some of the procedural issues that previously helped taxpayers. After the Tax Court’s decision in Green Valley Investors, LLC invalidated Notice 2017-10 on Administrative Procedure Act grounds, Treasury and the IRS finalized regulations re-designating certain syndicated conservation easement transactions as listed transactions.

The IRS also updated its conservation easement page in May 2026, warning that promoter-driven syndicated transactions often involve inflated valuations and that courts have repeatedly rejected abusive arrangements.

The result is a mixed picture. Some partnerships may have real procedural defenses. But investors should be careful not to assume that one taxpayer victory in one case applies to every partnership.
Penalty Approval Issues Should Still Be Reviewed
Penalty approval remains an important issue. Internal Revenue Code § 6751(b) generally requires written supervisory approval of certain penalties before assessment. In syndicated conservation easement cases, penalty approval has been a significant litigation issue.
On May 1, 2026, the Treasury Inspector General for Tax Administration issued a report titled “Procedures Are Needed to Prevent Backdating Penalty Approvals.” TIGTA stated that, after the Tax Court’s LakePoint decision, the IRS and the Office of Chief Counsel reviewed 1,268 syndicated conservation easement cases for compliance with § 6751(b). TIGTA found cases with backdated, missing, or otherwise deficient penalty approval documentation and stated that backdating penalty approvals undermines confidence in the fairness and integrity of tax administration.

For investors, this means penalty defenses should not be ignored. A partnership may have a penalty approval issue, even if the underlying deduction is weak. But penalty defenses are document-specific and timeline-specific. Investors should not assume that a penalty will be removed merely because other syndicated easement cases had penalty approval problems.
Interest May Be the Hidden Cost
Interest may be one of the largest components of the ultimate liability. The IRS settlement terms expressly state that interest accrues as required by law. Because many syndicated conservation easement cases involve old tax years, interest may run from the original due date of the return until the liability is paid.
That timing can make the economics much worse than the tax and penalty numbers suggest.
Investors should consider whether a deposit under IRC § 6603 may reduce further interest exposure while the case is pending. A properly designated § 6603 deposit can suspend the running of underpayment interest on a potential underpayment to the extent the deposit covers the amount ultimately due. This is not the same as conceding the issue, and it is not the same as making an ordinary payment. The designation and procedure matter.

Investors should also consider whether any interest abatement or refund arguments may apply. In particular, the developing COVID-era disaster postponement issues under IRC § 7508A, including Abdo and Kwong arguments, may be relevant for some taxpayers. These arguments are unsettled and should be separately evaluated, but they may matter where substantial interest accrued during the COVID-19 disaster period.
TEFRA and BBA Cases May Be Handled Differently
The IRS announcement distinguishes between TEFRA and BBA partnership cases.
For TEFRA cases, generally involving tax years 2017 and earlier, investors should expect IRS notices stating the amount owed by each investor after settlement and after the Tax Court decision becomes final.
For BBA cases, generally involving tax years 2018 and later, the partnership may be responsible for payment if it did not elect to push out the liability. If the partnership cannot pay, investors may later receive IRS notices reflecting amounts owed as a result of the settlement adjustments. If the partnership elected to push out the liability, it must furnish statements to investors and the IRS, and investors must take those adjustments into account.
This distinction matters because an investor may not control the partnership’s settlement decision, payment posture, push-out election, or documentation. Investors should obtain the partnership’s settlement letter, procedural history, tax year information, and counsel’s analysis before deciding how to vote or respond.
What Investors Should Ask Before Voting
Before accepting or rejecting the settlement offer, investors should evaluate several questions:
What tax year is involved?
Is the case governed by TEFRA or BBA?
What deduction was claimed?
What was the investor’s actual cash investment?
What deduction will the IRS allow for out-of-pocket costs?
What additional federal tax would result under the settlement?
What penalties apply under the 90-day, 45-day, and post-window outcomes?
How much interest has accrued?
Would a § 6603 deposit reduce additional interest exposure?
Are there state tax consequences?
Does the partnership have credible valuation, deed, appraisal, procedural, statute-of-limitations, or penalty approval defenses?
Has the partnership already lost or won related motions?
Is the case docketed in Tax Court?
Is trial scheduled?
Has the IRS issued a final partnership adjustment or final partnership administrative adjustment?
Were penalties timely approved under § 6751(b)?
Are there COVID-era interest arguments that should be preserved?
Investors should also compare the settlement cost with the downside of a trial loss. The decision is not just legal. It is economic.
The Practical Takeaway
The IRS’s renewed syndicated conservation easement settlement initiative is not a broad concession. The IRS continues to disallow the claimed charitable contribution deduction and continues to impose penalties and interest. But the early 90-day window may materially reduce penalty exposure compared with a litigation loss.
For many investors, the core question is whether the partnership has case-specific defenses strong enough to justify rejecting the offer. Procedural defenses, penalty approval issues, statute problems, or unique valuation facts may matter. But investors should weigh those defenses against the Tax Court’s generally unfavorable record for syndicated easement partnerships, the possibility of a 40% penalty, and years of accruing interest.
