How Lawyers Can Build a Stronger Case for Estate and Gift Tax Valuations
Estate and gift tax valuation disputes are rarely won by reciting a conclusion from an appraisal report. They are won by demonstrating that the reported value is the product of a disciplined process, reliable inputs, appropriate judgment, and a record that can withstand scrutiny years after the transfer or death.
For lawyers, the central task is not to become the appraiser. It is to help ensure the valuation is legally durable: grounded in the governing standard, tailored to the actual asset and transaction, and supported by contemporaneous evidence rather than retrospective rationalization.
Start With the Legal Question
The valuation exercise begins with the familiar fair-market-value standard: the price at which property would change hands between a willing buyer and willing seller, neither under compulsion and both having reasonable knowledge of relevant facts. In practice, however, that standard does not answer the most important questions.
Counsel should identify what exactly is being valued:
- A controlling interest or a noncontrolling interest.
- A liquid marketable asset or a restricted, illiquid interest.
- An operating business, holding company, family limited partnership, or investment entity.
- An interest subject to transfer restrictions, buy-sell provisions, governance limits, or pending transactions.
- Property affected by known or reasonably foreseeable events as of the valuation date.
Those distinctions determine the relevant market, the appropriate comparables, the reliability of projected cash flows, and whether discounts for lack of control or marketability are justified. A valuation report can be technically polished and still fail if it answers the wrong question.
Build the Record Before the Filing
Too many valuation disputes become difficult because the file was assembled after the tax return was filed. By then, the attorney and appraiser may be trying to recreate facts, explain missing assumptions, or defend a structure whose business purpose was never adequately documented.
The strongest cases are built contemporaneously. Lawyers should create a valuation record that includes:
- Organizational documents, ownership ledgers, and governing agreements in effect on the valuation date.
- Financial statements, tax returns, budgets, forecasts, and board materials.
- Documentation of the entity’s assets, liabilities, distributions, debt, and liquidity.
- Evidence supporting any non-tax purpose for the entity, transfer, or restriction.
- Communications and transaction documents relating to offers, negotiations, redemptions, sales, or financings.
- A clear timeline of facts known, knowable, and unforeseeable as of the valuation date.
This record protects more than the valuation conclusion. It protects the credibility of the entire estate-planning strategy.
Treat the Appraiser as a Strategic Partner
Lawyers should select valuation professionals with relevant subject-matter expertise, not merely a recognizable credential. An appraiser who routinely values operating companies may not be the right expert for a real-estate holding entity, a carried interest, a closely held professional practice, or a complex family investment vehicle.
The engagement also matters. Counsel should provide the appraiser with complete and accurate information, while avoiding pressure to reach a predetermined result. The objective is not to “get the number down.” It is to obtain an independent opinion that can be explained persuasively under examination.
That means asking the right questions early:
- What valuation approaches are appropriate and why?
- Which assumptions are most sensitive to change?
- Are the selected guideline companies or transactions genuinely comparable?
- How does the appraiser support each discount or premium?
- What facts could materially alter the conclusion?
A lawyer’s value lies in spotting legal and factual vulnerabilities before they become an IRS argument.
Make Discounts Defensible, Not Formulaic
Discounts often attract the greatest scrutiny because they can appear mechanical when they are not connected to the interest actually transferred. A minority discount should reflect the holder’s lack of control. A marketability discount should reflect the practical cost, delay, and uncertainty of converting the interest into cash.
The defense becomes stronger when the report explains the economic reality: transfer restrictions, absence of a ready market, distribution practices, concentration risk, governance rights, expected holding period, and the costs a hypothetical buyer would bear.
Generic discount studies may inform the analysis, but they should not substitute for asset-specific reasoning. The question is never whether a discount is common. The question is whether a hypothetical buyer would demand it for this interest on this date.
Defend Process, Not Just Outcome
A strong valuation defense is ultimately a narrative of reasoned decision-making. It shows that the client made a legitimate transfer, that the entity and its restrictions had real commercial significance, that the appraiser received reliable information, and that the reported value reflects conditions existing on the valuation date.
When lawyers focus only on the final number, they invite a battle of experts. When they build and preserve the process behind that number, they give the valuation the evidentiary foundation it needs to endure.
