Valuation and Discounts

Why the Fight Over Value Matters

Every transfer of wealth — whether a gift during life or a bequest at death — is subject to estate and gift taxes calculated on the fair market value of what is transferred. Fair market value is a legal standard: the price at which the property would change hands between a willing buyer and a willing seller, neither under any compulsion to act, both reasonably informed. That definition sounds precise, but applying it to a 30% stake in a private family business, a limited partnership interest, or a portfolio of real estate held inside an LLC produces a genuine range of defensible answers.

The stakes are high on both sides. A family that reports an artificially low value risks penalties, back taxes, and interest if the IRS successfully challenges the appraisal. A family that reports an inflated value pays more transfer tax than necessary. The contested middle ground — where legitimate professional judgment operates — is where valuation planning lives.

The Two Core Discounts: Minority and Marketability

Two categories of discount appear most frequently in estate and gift planning, and each reflects a real economic reality.

Minority Interest Discount

A minority interest discount reflects the reduced value of owning less than a controlling share of an entity. A buyer acquiring a 25% interest in a private company cannot direct its operations, force a dividend, or compel a sale. That lack of control is economically meaningful — a rational buyer would pay less for it than for the same proportional share of a company they could control. Appraisers supporting a minority discount typically reference comparable transactions in private-company interests and studies of control premiums paid in acquisitions.

Lack of Marketability Discount

A lack of marketability discount (sometimes called a DLOM) reflects the fact that an interest in a private entity cannot be easily sold. There is no stock exchange, no established market, and often significant legal restrictions on transfer. Liquidity has value; its absence reduces value. Appraisers estimate this discount using various methods, including studies of private transactions before companies went public and analysis of the cost of options that would provide liquidity.

These two discounts are conceptually distinct but often applied together. In aggregate, combined discounts for a minority, non-marketable interest in a closely held entity can be substantial — occasionally representing a significant reduction from underlying asset value. A qualified appraiser, not a rule of thumb, must support whatever figure is reported.

Entity-Based Planning and Its Scrutiny

Recognizing that holding assets inside an entity — a family limited partnership, a family LLC, or a similar structure — can produce valuation discounts when interests are transferred, families have long used these vehicles as part of gift and estate planning. When a parent contributes a portfolio of marketable securities or real estate to a family limited partnership and then transfers limited partnership interests to children, the transferred interests may be appraised at a discount to the pro-rata value of the underlying assets.

The IRS has challenged these arrangements aggressively when they lack economic substance beyond the tax benefit. Courts have disregarded discounts — and in some cases the entity itself — when transfers occurred near death, when the entity never operated as a genuine business, when the senior generation retained practical control over distributions, or when personal and entity finances were commingled. The relevant legal doctrines include arguments that the transfer was effectively of the underlying assets directly (not the entity interests) and that no genuine non-tax purpose existed.

Families considering entity structures for legitimate non-tax purposes — centralized management, creditor protection, governance over family assets, facilitating business succession — may also receive favorable valuation treatment when interests are transferred. The distinction between planning with genuine substance and planning whose sole purpose is discount manufacturing is one courts draw carefully, and one that attorneys and appraisers take seriously. The regulatory environment surrounding these structures has evolved over time and continues to be an area of active legal development; a qualified attorney must evaluate any particular family's circumstances.

Appraisals, Qualified Appraisers, and the Paper Trail

A valuation used to support a gift or estate tax return must generally be prepared by a qualified appraiser — a professional who meets specific education, experience, and independence standards set by tax law and Treasury regulations. The appraiser must apply a recognized method: income approaches (discounted cash flow), market approaches (comparable transactions or public-company multiples), or asset-based approaches, depending on the nature of the entity.

The appraisal report itself must meet detailed requirements to be considered a "qualified appraisal" for tax purposes. A report that is technically sound but fails procedural requirements can be disregarded, leaving a family exposed to penalties. Common documentation failures include appraisals completed after the transfer date, reports that lack required identifying information, or analyses that don't adequately support the discount percentages applied.

Equally important is the underlying record — operating agreements, meeting minutes, financial statements, tax returns, and transfer documentation. When the IRS examines a valuation, these materials tell the story of whether the entity operated as represented and whether the transfer was structured as documented. For transfers involving installment sales to trusts or other sophisticated techniques, the business records supporting value on the transaction date are foundational to the entire structure's integrity.

Formula Clauses as a Professional Tool

Because the fair market value of a private entity interest is determined by an appraisal that may later be disputed, estate planners sometimes use formula clauses in gift documents. Rather than transferring "25 limited partnership units," a formula clause might transfer "the number of units having a fair market value of [dollar amount] as finally determined for gift tax purposes." If the IRS later asserts a higher value, the formula clause automatically adjusts the number of units transferred — in theory preventing a taxable gift larger than intended.

Courts have upheld formula clauses in certain forms and rejected them in others. The drafting details matter enormously. Formula clauses that rely on a final determination by a court or tax authority have fared better than those that depend on an upfront number that could be challenged as circular. This is an area where experienced estate attorneys draft carefully and the case law is still developing.

Questions to Ask and Common Mistakes

Families navigating a valuation question benefit from asking their advisers directly: What method will the appraiser use, and why is it appropriate for this type of entity? How defensible are the proposed discount levels given recent court decisions? Does the entity have genuine non-tax purposes documented in its formation and operating history? Has the family maintained clear separation between personal and entity finances?

Common mistakes include treating the appraisal as a formality rather than a substantive analysis, selecting an appraiser primarily on the basis of the discount they will opine, failing to update appraisals when circumstances change, and gifting interests in entities that were never properly operated. Discount levels that significantly exceed those seen in comparable transactions invite scrutiny, and appraisals not completed contemporaneously with the transfer are vulnerable to challenge.

Valuation is ultimately a legal and professional matter, not a mechanical calculation. Attorneys, CPAs, and certified appraisers with specific experience in estate and gift contexts must be involved from the earliest stage of planning — not called in to ratify decisions already made.
