FOR ESTATE PLANNERS, FAMILY-OFFICE PRINCIPALS, BUSINESS OWNERS, AND THE APPRAISERS WHO DEFEND THE NUMBERS

A $50M business is rarely worth $50M for estate tax purposes.

Closely-held business interests get marketability and minority-interest discounts that the IRS hates but the courts have repeatedly upheld. A properly-structured transfer can reduce a $50M business value to a $25-35M reportable value — saving $6-10M in federal estate tax at the 40% rate. The mechanics: DLOM (lack of marketability) + DLOC (minority interest) + §2703 buy-sell defense + Rev. Rul. 59-60 documentation + IRS-challenge defense framework.

STAGE 1 OF 5

The business (un-discounted value)

Defaults model a $50M private business being gifted in a typical FLP/FLLC structure. Use the DCF Sanity Check to derive the un-discounted enterprise value.

FMV of the entire business as a going concern. Get from DCF, EV/EBITDA comps, or a formal appraisal. Note: this is BEFORE marketability and minority discounts.
$
Subtracted to get equity value. Most estate-planning valuations work from equity value, since gifted/bequeathed interests are equity interests.
$
Drives discount magnitudes. Operating businesses receive lower discounts than holding companies. Real-estate-only entities get higher discounts (lower marketability for fractional RE interests).
If the entity regularly distributes cash to owners, marketability discount is LOWER (the holder gets cash). If it retains earnings (no distributions), discount is HIGHER. IRS factor.
Why discounts work — and why the IRS keeps fighting them. A 30% interest in a $50M public company is worth $15M (you can sell it any business day). A 30% interest in a $50M private company is NOT worth $15M — there's no buyer (or only a few specialized buyers at unfavorable terms), and you can't force a distribution. The illiquidity has real value-destroying impact, hence the discount. The IRS challenges discounts because they're a major estate-tax-reduction lever; the courts (Tax Court, Ninth Circuit, Fifth Circuit) have repeatedly upheld 25-40% combined discounts when properly documented.
STAGE 2 OF 5

The interest being valued

Specifically what is being gifted, bequeathed, or otherwise transferred — and how is it structured.

A 49% interest gets a minority discount (no control). A 51%+ interest may get NO minority discount (control means no DLOC). For estate planning, the discount opportunity is greatest with minority blocks.
%
FLP and FLLC structures are estate-planning vehicles specifically designed to hold business interests with restricted transferability. They typically support higher DLOM/DLOC than direct corporate stock.
Drives the valuation date. Date-of-death (alternate valuation date 6 months later, if elected). Date-of-gift. Lifetime transfer to GRAT, IDGT, etc.
FLP/FLLC operating agreements typically restrict transfers (right of first refusal, no transfer without GP/Manager consent, etc.). These restrictions support DLOM. CRITICAL: §2703 says restrictions imposed for tax purposes are DISREGARDED — must be bona fide business arrangement at arms-length terms.
The 49% vs. 51% mathematical step. A 49% interest gets a minority-interest discount (you can't control board, distributions, M&A decisions). A 51% interest doesn't (you control everything). This creates the "fractional gifting" strategy: gift 49% to children in trust, retain 51% control until death, then bequeath the remaining 51% (which itself becomes the new minority interest after the first gift). Estate planners often build out 30-49% transfers to maximize discount stacking.
STAGE 3 OF 5

Discount for Lack of Marketability (DLOM)

DLOM compensates for inability to convert the interest to cash quickly. Empirical studies (restricted-stock, pre-IPO) suggest 20-45% range. IRS scrutinizes; documentation matters.

Typical range by business type: operating with regular distributions = 20-25%. FLP holding marketable securities = 25-35%. FLP holding RE only = 30-40%. Restricted operating with no distributions = 35-45%. Defensible studies: Mandelbaum (Tax Court 1995), Stout Risius Ross, Mercer Capital, Pluris.
%
Defensibility matters more than magnitude. Cite specific empirical study; tie to comparables; address Mandelbaum factors (size, distributions, restrictions, holding period, info access, etc.).
The Mandelbaum 9 factors that defend a DLOM. Tax Court (Mandelbaum v Commissioner, 1995): (1) financial statement analysis, (2) dividend / distribution history, (3) nature of company + history, (4) management, (5) amount of control, (6) restrictions on transferability, (7) holding period, (8) redemption policy, (9) costs of public offering. A DLOM appraisal that addresses all 9 factors with specific evidence is defensible. One that just cites "30% per Pluris study" is weak — the IRS will challenge.
STAGE 4 OF 5

Minority Interest Discount & §2703 Buy-Sell Test

DLOC (Discount for Lack of Control) plus the buy-sell agreement test under IRC §2703.

Compensates for inability to control distributions, sale, board composition, M&A. Typical range 15-30%. Higher for entities with history of low distributions, minority-unfriendly governance, family control struggles. Lower for entities with regular distributions and minority-protective provisions.
%
Empirical bases: Partnership Profiles studies, Mergerstat Control Premium Studies (1 − 1/[1 + control premium]), Houlihan Lokey Control Premium Studies. Courts accept 15-30% range when documented properly.
If yes, agreement may set the valuation. §2703 requires: (1) bona fide business arrangement, (2) not a device to transfer to family for less than full and adequate consideration, (3) terms comparable to those of arms-length similar agreements. Family-only buy-sells often fail #3.
Some practitioners cap combined DLOM + DLOC at 50% to reduce IRS challenge risk. The math compounds: if DLOM = 30% and DLOC = 20%, combined is 1 − (1 − 0.30)(1 − 0.20) = 44%. Above 50% combined, courts get skeptical.
How the discounts COMPOUND, not add. A 30% DLOM applied to a 20% DLOC is NOT a 50% combined discount. It\'s 1 − (1−0.30)(1−0.20) = 44%. Apply DLOC FIRST (to get a minority interest value) then DLOM (because the minority interest itself is illiquid). $1M of equity × (1−0.20) × (1−0.30) = $560K. Saves you 44% of the un-discounted value × 40% federal estate tax = 17.6% effective tax savings on the discounted portion.

Estate-planning business valuation is a regulated practice; appraisals must be performed by qualified appraisers per IRS Reg §301.7701-15 for gifts > $5,000 and estate returns. The model uses representative DLOM/DLOC ranges from established empirical studies (Mandelbaum factors, Mercer/Pluris/Stout studies) but is NOT a substitute for a qualified appraisal report. Material decisions require formal appraisal with full Rev. Rul. 59-60 documentation. Recent IRS-challenged cases include: Estate of Adams, Estate of Murphy, Estate of Holman, Estate of Strangi, Estate of Bigelow, Estate of Liljestrand, Estate of Powell. Fee for qualified appraisal: $5,000-25,000 typical for estate planning context. This is not legal, tax, or appraisal advice. Engage qualified estate counsel and a credentialed appraiser (ABV, ASA, CVA) for any actual transfer.
