Estate and Gift Tax Valuation Discounts

DLOM and DLOC discounts can reduce the taxable value of a transferred business interest by 30–50%. Here's how they work and what survives IRS scrutiny.

Why Discounts Matter for Estate & Gift Tax

The federal estate and gift tax exclusion is generous (~$13.6M per person in 2024) but the rate above the exclusion is 40%.
Transferring business interests to children, trusts, or family-limited partnerships at fair market value with appropriate discounts can shift significant value out of the taxable estate.
A combined 30–40% discount on a $5M minority interest reduces the taxable transfer by $1.5–2M — saving $600K+ in tax.
But discounts must be defensible — IRS aggressively challenges aggressive discounts, and Tax Court has reduced or rejected many.

Lack of Marketability Discount (DLOM)

Reflects that private company shares can't be quickly converted to cash — there's no liquid market.
Typical range: 15–35% for private companies, depending on profitability, dividend policy, expected holding period, restrictions on transfer.
Empirical support: pre-IPO studies (Mandelbaum factors), restricted stock studies, option-pricing models.
Higher for closely-held businesses with restrictive shareholder agreements; lower for businesses with active buyer pools or imminent liquidity events.

Lack of Control Discount (DLOC) / Minority Discount

Reflects that a minority owner can't unilaterally direct the company — can't force sale, dividends, hiring, or strategy.
Typical range: 15–25% — derived from the inverse of control premiums observed in public-company acquisitions.
DLOC applies to minority interests being valued; doesn't apply to controlling interests.
Combined with DLOM, the two discounts compound (multiply, not add): a 25% DLOC + 30% DLOM = 47.5% combined discount.

What the IRS and Tax Court Look For

Qualified appraiser — credentialed (ASA, CVA, ABV) and independent. DIY valuations are nearly always rejected.
Documented methodology — every discount supported by empirical data and case-specific analysis, not just rules of thumb.
Adequate disclosure on Form 709 (gift tax return) — using the 'adequate disclosure' rules starts the 3-year statute of limitations.
Real economic substance — courts have rejected discounts where the family-limited partnership had no real business purpose other than tax reduction.
Consistency — discounts claimed for gift tax must be defensible if challenged later for estate tax.

Common Pitfalls

Claiming discounts on revocable trust transfers or transfers between spouses — neither typically supports discounts.
Using overly aggressive discount percentages (50%+ combined) without strong supporting analysis — invites audit.
Failing to update valuations as the business changes — old appraisals don't survive scrutiny.
Treating valuation as a one-time event — succession planning needs periodic re-valuation as values shift.
Anti-clustering rules and chapter 14 (Section 2701–2704) impose specific requirements on family transfers — coordination with estate counsel is essential.
