Valuation Discounts for Estate and Gift Taxes: Rules and Penalties

Valuation discounts for estate and gift taxes lower the taxable value of a transferred interest when that interest is hard to sell or carries no control, often by 20% to 40% or more. The federal estate and gift tax still tops out at 40% on transfers above the basic exclusion, which for 2026 is $15,000,000 per individual after the One, Big, Beautiful Bill raised the threshold and made it permanent.¹ Even with that exemption, families holding closely held businesses, investment partnerships, or significant real estate can face a taxable estate where a well-supported discount saves millions. The IRS allows these discounts when they reflect real economic limits on the transferred interest, and challenges them hard when the structure looks built for tax reduction rather than a genuine business reason.

Why Discounts Exist

Estate and gift tax is calculated on the fair market value of what is transferred, defined as the price a willing buyer and willing seller would agree on, with neither compelled and both reasonably informed.² For public stock, that price is a lookup. For a 15% interest in a family LLC that owns apartment buildings, it takes professional judgment.

The gross estate includes all property the decedent owned at death, real or personal, tangible or intangible, and for unlisted securities the statute directs appraisers to consider comparable public companies.³ Valuation is an estimate grounded in market realities, and those realities include the practical disadvantages of owning an interest that can’t be sold easily or controlled at all. That gap between a mathematical share of net asset value and what a real buyer would pay is where discounts live.

The Lack of Marketability Discount

Marketability discounts address one problem: an interest in a private entity can’t be sold on a stock exchange. A prospective buyer of a minority stake in a family partnership may hold the interest for years before any liquidity event, and there’s no certainty a buyer can be found at all. That reduces what the interest is worth compared to its proportional share of the entity’s net assets.

Appraisers quantify the discount using empirical studies of restricted stock and pre-IPO transactions, where the price gap between freely tradable and restricted shares provides a benchmark. Restricted stock studies commonly show discounts of 20% to 35%, and pre-IPO studies often indicate higher figures. The specific transfer restrictions in the operating or partnership agreement drive where the number lands. An agreement that flatly bars transfers without unanimous consent supports a larger discount than one requiring only a managing partner’s approval.

Marketability discounts also apply to controlling interests in private entities. A 70% owner of a private company still can’t sell on an exchange. The discount shrinks for a controlling interest because the owner can force a sale or liquidation, but it doesn’t vanish.

The Lack of Control Discount

Also called a minority interest discount, this one compensates for the powerlessness of a non-controlling stake. Someone with a 20% limited partnership interest cannot force distributions, cannot compel a sale of assets, cannot hire or fire management, and cannot dissolve the entity. They depend on whoever controls the entity to make decisions that may or may not benefit them.

The size of the control discount depends on the specific rights the minority holder lacks under the governing documents. No voting rights, no ability to demand distributions, and no right to force liquidation together justify a larger discount than a structure where the holder retains some voice in major decisions. Appraisers look at publicly traded closed-end funds or comparable private transactions to measure the gap between controlling and non-controlling value.

The two discounts address different problems, and the IRS watches carefully for double-counting. Marketability is about finding a buyer at all. Control is about what the buyer can do once they own the interest. An appraiser who attributes the same limitation to both discounts hands the IRS an easy adjustment argument.

Which Assets Qualify

The most common candidates are equity interests in closely held corporations, partnerships, and LLCs. These entities have few owners and no public market, which triggers both factors. A non-managing LLC interest or a limited partnership interest is the classic case: illiquid and powerless by design.

Fractional interests in real estate also qualify. A 40% undivided interest in a commercial building means the recipient co-owns with others but can’t sell the whole building, can’t control its management, and would need to bring a partition suit to force a sale. The cost, delay, and uncertainty of that process pull the interest’s value below its mathematical share.

Families often consolidate marketable securities, real estate, or other passive assets into a single entity and then transfer non-controlling interests to younger generations. The discount applies to the entity interest, not to the underlying assets. A 25% limited partnership interest in a family entity holding $10 million in publicly traded stock is not worth $2.5 million, because the recipient cannot reach in and sell the shares. They own an illiquid, non-controlling partnership interest. This structural layering is widely accepted but draws heavy scrutiny, so the entity needs a real business purpose, proper formation, and ongoing operational formalities.

What Can Wipe Out the Discount

Two provisions do most of the damage when the IRS challenges a discount: Section 2036 and Section 2704.

Section 2036 and Retained Control

Section 2036 pulls transferred property back into the taxable estate at full fair market value, with no entity-level discount, if the decedent retained the right to income from the property or the right to control who enjoys it, for life or until death.⁴ This is the single biggest threat to a discount claim, because it doesn’t reduce the discount, it eliminates the transaction.

The escape hatch is Section 2036(a)’s own exception for a bona fide sale for adequate and full consideration.⁴ To qualify, the entity transfer needs a legitimate non-tax business purpose, such as centralized management, creditor protection, or consolidating family investment decisions. Courts have applied the exception generously when the facts show genuine operations and rejected it when the entity is a title-holding shell for the decedent’s personal assets.

The behaviors that trigger a Section 2036 challenge form a predictable pattern: paying personal expenses out of entity funds, retaining unilateral power to dissolve, commingling entity and personal accounts, or creating the entity on a deathbed. In Estate of Fields v. Commissioner (2024), the Tax Court denied all discounts for a family limited partnership created less than a month before the decedent died, finding no substantial non-tax purpose and effective retained control until death.

Section 2704 and Applicable Restrictions

Chapter 14 of the Internal Revenue Code carries special valuation rules aimed at families deflating taxable values through creative structures.⁵ Section 2704(b) targets restrictions on liquidation rights within family-controlled entities. It requires the IRS to disregard certain “applicable restrictions” when valuing a transferred interest if the transfer is to a family member and the family collectively controlled the entity immediately before the transfer.⁶ An applicable restriction is one that limits the entity’s ability to liquidate and that the family has the power to remove after the transfer. If the family wrote a partnership agreement barring liquidation but could collectively vote to change it tomorrow, the IRS can ignore that restriction when calculating the discount.

Two exceptions matter. A restriction imposed by federal or state law survives Section 2704(b), as does a commercially reasonable restriction from financing with an unrelated lender.⁶ Default state law limitations on partnership liquidation generally cannot be disregarded, which is why entity choice and state of formation carry real weight.

What a Defensible Appraisal Looks Like

A discount without a formal written appraisal will not survive audit. The appraisal must be prepared by a qualified appraiser with verifiable education and experience in the specific type of property. Under federal regulations, that means either professional or college-level coursework in the relevant property type plus at least two years of experience, or a recognized designation from a professional appraisal organization demonstrating competency.⁷ Accredited Senior Appraiser (ASA) from the American Society of Appraisers or Member of the Appraisal Institute (MAI) both satisfy the designation route.

The analytical framework comes from Revenue Ruling 59-60, the longstanding guidance on valuing closely held business interests. The appraiser analyzes the company’s history, financial condition, earning capacity, economic outlook, and the specific terms of the interest being transferred. Three approaches typically come into play:

Income approach: value based on the present worth of expected future cash flows, discounted for risk.
Market approach: comparison to similar publicly traded or privately sold companies.
Asset approach: net value of the entity’s assets, adjusted for the nature of the interest transferred.

After arriving at an enterprise-level or pro-rata value, the appraiser applies the marketability and control discounts separately, each with its own supporting analysis. The marketability figure must reference empirical data from restricted stock or pre-IPO studies. The control figure must tie back to the specific rights withheld by the governing documents. The appraisal states the final fair market value after discounts and attaches to Form 706 for estates or Form 709 for gifts.

Fees vary widely. Simple entities may run a few thousand dollars; complex multi-entity structures with diverse holdings can reach well into five figures. An unsupported or poorly reasoned appraisal can result in the IRS disallowing the entire discount and adding penalties on top of the extra tax.

Reporting the Gift and Starting the Clock

Filing a gift tax return is only half the job. The gift must be adequately disclosed for the statute of limitations to begin running. Without adequate disclosure, the IRS can challenge the valuation at any time, with no deadline.⁸ The same is true for gifts never reported.

Adequate disclosure triggers the standard three-year statute of limitations. Once that window closes, the IRS cannot revalue the gift, and the value becomes finally determined. That protection matters most for discounted entity interests the IRS might otherwise revisit years later when the estate return is filed.

The return needs to include:

A complete Form 709, with the identity and relationship of the donor and each recipient.
A description of what was transferred and any consideration received in return.
For property placed in trust, the trust’s EIN and a description of its terms, or a copy of the trust document.
A qualified appraisal or a detailed explanation of the valuation method.

These come from the Form 709 instructions and the underlying regulations.⁹ For transfers subject to Chapter 14, the regulation specifically requires a description of the entire transaction or series of transactions, including retained interests.¹⁰ Attaching the full appraisal report is the safest approach and cuts off most arguments about methodology.

The 2026 annual gift tax exclusion is $19,000 per recipient, so transfers below that amount don’t require a Form 709 at all.¹ For discounted entity interests, filing anyway with full valuation disclosure starts the three-year clock and prevents the IRS from later arguing the discounted value was wrong and the transfer exceeded the exclusion. Filing a return you didn’t technically need to file is a small price for that certainty.

Penalties for Valuation Misstatements

Aggressive valuations don’t just get adjusted. They get penalized, and the thresholds trip more easily than most people expect.

A substantial estate or gift tax valuation understatement occurs when the reported value is 65% or less of the correct value. If the resulting underpayment exceeds $5,000, the penalty is 20% of that underpayment. For a gross valuation misstatement, where reported value is 40% or less of the correct value, the penalty doubles to 40%.¹¹

The math moves fast. If an entity interest is actually worth $3 million and the taxpayer reports $1.9 million after discounts, the reported value is roughly 63% of the correct value, tripping the 20% penalty. Report $1.1 million, and it’s below 40%, bumping the penalty to 40% of the underpayment.

The main defense is reasonable cause and good faith. The penalty doesn’t apply if the taxpayer had a reasonable basis for the reported value and acted in good faith.¹² Relying on a qualified appraiser is the strongest form of that defense, but the reliance must be objectively reasonable: the taxpayer has to have given the appraiser complete and accurate information, and the appraiser needs genuine expertise in the property type. A rubber-stamp appraisal protects no one.

Practical Steps That Protect the Discount

The cases where discounts survive share a set of habits. The cases where they don’t share a different set.

Form the entity well before any anticipated transfer. Entities created on a deathbed or shortly before a large gift draw immediate suspicion, and a track record of legitimate operations strengthens the business-purpose argument.
Document the business purpose at the time of formation: centralized management of family investments, creditor protection, educating younger generations. Put it in writing before an audit begins, not after.
Maintain entity formalities: separate bank accounts, regular meetings or documented management decisions, financial statements, and timely K-1 filings.
Avoid personal use of entity assets. The moment entity funds pay personal expenses, the Section 2036 argument writes itself. Keep personal and entity finances completely separate.
Retain sufficient personal assets outside the entity. Moving nearly everything into the entity while keeping nothing to live on or pay estate taxes suggests the transferor never truly gave up control.
Hire a qualified appraiser early. The appraisal should be completed at or near the valuation date, using current financial data. Retroactive appraisals prepared during an audit persuade far less.
