Key Takeaways
How the conservation easement deduction works, who qualifies for it, what the perpetuity condition costs, and where the deduction gets disallowed.
- The statute requires the restriction to be “granted in perpetuity” and the conservation purpose to be “protected in perpetuity”, so the limitation is permanent by law rather than by choice
- An IRS document puts the ceiling at 50 percent of the donor’s contribution base with a 15-year carryforward, and 100 percent for a qualified farmer or rancher
- The deduction needs a signed qualified appraisal by a qualified appraiser and Form 8283, paid for by the donor before any deduction exists
- Where the donor is an ultimate member of a partnership or S corporation, Publication 526 says the contribution is not treated as qualified and no one may claim a deduction
- Congress wrote three exceptions to that disallowance and the 2024 listed-transaction regulation declines to adopt any of them
A conservation easement tax deduction is a charitable contribution deduction for giving away the right to develop your own land. You keep the title, you keep possession, and a qualified organization holds an enforceable restriction on what can be done with the ground from then on.
The deduction is real and the IRS has spent a decade litigating the aggressive end of it. What gets lost is that the condition making the deduction available is the same condition making the land permanently harder to sell.
This post walks the statute and current IRS guidance in order: what qualifies, who qualifies, the ceiling, the appraisal, and the two places the deduction gets taken away. It is information, not tax or legal advice. Whether your parcel qualifies is a question for a CPA and an attorney licensed where the land sits, before you sign anything.
Quick verdict: The deduction works and the rules are knowable. Price the perpetuity before the deduction, because the restriction binds every future owner of the parcel while the deduction is capped by your own income and expires as a carryforward after fifteen years.
What is a conservation easement tax deduction?
It is a charitable deduction for the value of a development right you give up permanently. The donation is not of land but of a restriction on land you keep.
Under 26 U.S.C. 170(h), the statute calls this a qualified conservation contribution, and it has to satisfy three conditions at the same time. The gift must be a qualified real property interest. It must go to a qualified organization. And it must be made exclusively for conservation purposes.
Miss any one of the three and there is no deduction. Not a reduced deduction, none.
The effect on the parcel is what sellers discover later. The restriction is recorded so the holder can enforce it, which means it is there for whoever owns the ground next. That is a specific marketing problem, and the guide to sell problem land covers how constrained parcels move.
Who qualifies for the conservation easement deduction?
Three things have to line up: the interest, the recipient, and the purpose. The purpose test is where an ordinary parcel either fits or fails.
The qualified real property interest can be your entire interest other than a qualified mineral interest, a remainder interest, or, the one this post is about, “a restriction (granted in perpetuity) on the use which may be made of the real property.” The qualified organization must be a governmental unit or a qualifying public charity, not any nonprofit that will take it.
The conservation purpose list is a closed set of four. Preserving land for outdoor recreation or public education. “(ii) the protection of a relatively natural habitat of fish, wildlife, or plants, or similar ecosystem,”. “(iii) the preservation of open space (including farmland and forest land)” where it is for scenic enjoyment or under a governmental conservation policy “and will yield a significant public benefit, or”. Preserving a historically important land area or a certified historic structure.
Read that list against your own parcel honestly. Timber ground can fit the open space and habitat tests, and what the asset is worth drives the appraisal, which the guide to timber land value sets out. Land whose only claim is being undeveloped has a harder case, because the open space test wants scenic enjoyment or a stated public policy plus a significant public benefit, not the absence of buildings.
Why does the deduction require perpetuity?
Because the statute says so twice, in two different places, and the IRS treats it as the foundation of the whole provision.
The first instance is inside the definition of the interest itself: the restriction must be “granted in perpetuity.” The second is a separate test on the purpose, where “A contribution shall not be treated as exclusively for conservation purposes” “unless the conservation purpose is protected in perpetuity.”
The IRS’s own introduction to conservation easements, published at irs.gov in January 2020, reduces it to five words: “Perpetuity is a fundamental requirement.” The same document calls what is created “Permanent restrictions on use of land or buildings”, and notes the restrictions must be “enforceable by the donee organization”, for example “by recordation in land records.”
That is the trade, stated without decoration. A one-time deduction, capped by your income, for a permanent restriction recorded against the parcel that no future owner can undo. A restriction of this kind can both preserve and limit recreational use, and the guide to recreational land value shows how much of a parcel’s price that use carries.
How much can you actually deduct?
Up to 50 percent of your contribution base, with fifteen years to use the excess, and 100 percent if you are a qualified farmer or rancher.
Those figures come from the IRS document cited above, dated January 2020: “An individual may deduct a qualified conservation easement contribution up to 50% of the individual’s contribution base”, where “Contribution base of an individual is generally adjusted gross income”, and “For conservation easements, the carryover period is 15 years.” For capital gain property generally the limit is “generally limited to 30% of an individual’s contribution base”, so a conservation contribution gets a higher ceiling than an ordinary donation of appreciated property.
The date on that document matters and is disclosed here on purpose. The same figures sit in section 170(b)(1)(E), but the readily fetchable 2011 edition of that paragraph contains a clause stating it “shall not apply to any contribution made in taxable years beginning after December 31, 2011.” The provision survived that date, which is why the IRS stated the same figures in 2020 and still organizes Publication 526 around them. The old text does not say so. Publication 526 for 2025 still organizes the deduction the same way, with conservation contributions under a 50 percent limit and farmers and ranchers under a 100 percent limit. Confirm the current figures against the current publication with your CPA before you file.
Note what the ceiling does. It caps the deduction against your income, so a restriction worth far more than half your income cannot be deducted at that value in any one year, and the unused part expires after fifteen.
What appraisal does the IRS require?
A signed qualified appraisal by a qualified appraiser, with Form 8283 attached to the return. You pay for it first, and the deduction does not exist until the valuation does.
Publication 526 (2025) states the substantiation requirement as “A signed qualified appraisal, performed by a qualified appraiser“, filed on “Form 8283, completed as specified in the Instructions for Form 8283.” The IRS’s training document lists the records an examiner asks for, calling them the five key documents for audit, among them the appraisal, the contemporaneous written acknowledgment, and the baseline documentation report.
Two consequences follow. The appraisal is an out-of-pocket cost incurred before any tax benefit, and the valuation is what the IRS litigates, which is the subject of the regulation cited further down. What a county says a parcel is worth and what a market says are different questions, and the guide to assessed value vs market value separates them.
Why are partnership easement deductions disallowed?
Because Congress wrote a rule aimed squarely at them, and in current IRS guidance it does not reduce the deduction, it removes it.
Publication 526 for 2025 puts it in one sentence. Where the taxpayer is an ultimate member of a partnership or S corporation, “the contribution is not treated as a qualified conservation contribution and no one may claim a deduction.” The publication then says “There are three exceptions to the section 170(h)(7) disallowance rule”, and identifies them as a contribution outside the three-year rule period, a family pass-through entity, and a certified historic structure.
The structure being shut down is simple: investors buy into an entity, the entity donates an easement, and the deduction passed through is a multiple of what each investor paid in.
What makes a syndicated easement a listed transaction?
Promotional material offering a deduction of two and a half times what the investor puts in. That is the trigger, and it is deliberately separate from whether the deduction survives.
Treasury published final regulations on 8 October 2024, TD 10007 at 89 FR 81341, identifying syndicated conservation easement transactions as listed transactions at 26 CFR 1.6011-9, effective the same day. The test is whether the taxpayer received material offering a deduction the amount of which “equals or exceeds an amount that is two and one-half times the amount of the taxpayer’s investment”, a threshold the preamble calls “a bright line”.
Now the part that catches people. Congress wrote three exceptions to the deduction disallowance. The regulation does not adopt them. The preamble states that the final rules do not, in its words, “include any exceptions for transactions described in section 170(h)(7)(C) through (E)”, and that a transaction is “nevertheless a listed transaction with respect to any partner” who received the offering material.
So a deal can fall inside one of Congress’s three exceptions, keep its deduction, and remain a listed transaction with the disclosure obligations and penalty exposure that carries. The exception that saves the deduction does not save you from the reporting regime. The two figures measure different quantities: the statutory disallowance looks at the contribution, the regulation at what a promoter offered against what an investor paid.
One more detail worth carrying: the same document records that “Notice 2017-10 is obsoleted for transactions occurring after October 8, 2024.” Guidance still pointing to that notice as the operative authority is pointing at something superseded.
What does the easement do to the land afterward?
It stays. The restriction is recorded against the parcel and granted in perpetuity, so the next owner takes the land with the limitation already on it and without the deduction.
That split is the structural fact to understand before signing. The deduction is personal to the donor, capped by the donor’s income, used up within fifteen years. The restriction is attached to the ground, enforceable by the holder, permanent. The person who receives the benefit and the people who live with the burden are not the same people.
For a buyer this is a diligence item, not a deal-breaker. A restricted parcel can be a good purchase at the right price, and the restriction may protect exactly what a recreational buyer wants. What it changes is the buyer pool and the price, because the development option that would set the ceiling has been removed.
The clearest case is where land passes down. An heir can inherit acreage already restricted by a donation someone else deducted, and the guide to sell inherited land deals with the sale side of that.
Is a conservation easement deduction worth it on vacant land?
It depends on whether you want the land preserved for its own sake, because the costs below come out of the deduction before anything is left over.
Add up what the donation requires. A qualified appraisal paid up front. Legal drafting of the instrument. A holder willing to take it and monitor it. A conservation purpose that fits the statutory list. And a permanent reduction in what the parcel can ever be used for.
Set that against the ceiling. The deduction is limited by a percentage of your contribution base, so a modest income absorbs a large valuation slowly, and the carryforward runs out. For an owner whose goal is value out of the ground, the comparison is the net from a sale, and the guide to cost to sell land prices that side.
The donation makes sense where the owner wants the restriction for its own sake, intends to hold the land anyway, has a parcel that clearly meets a conservation purpose, and has income large enough that the ceiling does not waste the valuation.
What should you verify before donating or buying?
Work the qualification question before the valuation question, because a parcel that fails the statutory tests cannot be rescued by a good appraisal.
- Confirm which of the four conservation purposes your parcel meets, in the statute’s words rather than a brochure’s paraphrase.
- Verify the holder is a qualified organization under 170(h)(3), meaning a governmental unit or a qualifying public charity, not any nonprofit willing to accept it.
- Read the perpetuity language in the draft instrument. The restriction must be granted in perpetuity and the purpose protected in perpetuity. Both are conditions of the deduction.
- Budget the qualified appraisal as a cost, not a formality. It is paid before the deduction exists and the valuation is what gets litigated.
- Ask a CPA how the ceiling applies to your actual income, including whether the fifteen-year carryforward is long enough to absorb the valuation.
- If any pass-through entity is involved, ask about section 170(h)(7) first. The deduction may be disallowed outright, and clearing one of the three exceptions does not clear the listed-transaction rules.
- If you are buying restricted land, get the recorded instrument and read the restrictions, because they bind you and you get no deduction for them.
None of this is tax or legal advice, and the qualification question in particular turns on facts about your parcel that no article can assess.

Frequently Asked Questions
How much is a conservation easement tax deduction worth?
The deduction equals the value of the restriction given up, established by a signed qualified appraisal from a qualified appraiser. An IRS document puts the annual ceiling at 50 percent of the donor’s contribution base, which is generally adjusted gross income, with a 15-year carryforward and 100 percent for a qualified farmer or rancher. Confirm current figures with a CPA.
Does a conservation easement have to be permanent?
Yes. Section 170(h) requires the restriction to be “granted in perpetuity” and separately requires that the conservation purpose be “protected in perpetuity.” The IRS states that perpetuity is a fundamental requirement. A time-limited restriction does not support a qualified conservation contribution, and the limitation stays recorded against the parcel for every later owner.
Can a partnership claim a conservation easement deduction?
Often not. IRS Publication 526 for 2025 says that where the taxpayer is an ultimate member of a partnership or S corporation, the contribution is not treated as a qualified conservation contribution and no one may claim a deduction. Three exceptions exist under section 170(h)(7), covering the three-year rule period, family pass-through entities, and certified historic structures.
What is a syndicated conservation easement?
A deal where investors buy into a pass-through entity that donates an easement and passes out deductions larger than what each investor paid in. Final regulations effective 8 October 2024 identify these as listed transactions at 26 CFR 1.6011-9 where promotional material offers a deduction of at least two and a half times the investment.
Can you build on land with a conservation easement?
It depends entirely on the recorded instrument, which may reserve a building envelope or may bar structures altogether. The restriction is a private agreement enforceable by the holder, so the document controls, and it is separate from zoning. Get the recorded easement before you buy and read what it reserves, then confirm permitting with the county.
