An estate appraisal is not simply a current appraisal with a historical date added to the report. In many cases, the appraiser must develop an opinion of what the property was worth as of the date of death, even though the inspection takes place months or sometimes years later. That requires the appraiser to look back at the market as it existed on the effective date. Comparable sales, available inventory, buyer behavior, financing conditions, and neighborhood influences should all be considered within the context of that earlier period.
The condition of the property may also have changed since the date of death. Repairs may have been completed, updates may have been made, or deferred maintenance may have occurred. A credible appraisal should explain what condition is being valued and what information was used to understand the property as it existed on the retrospective date.
The goal is not simply to produce a value. The report should provide enough market evidence and explanation for the executor, attorney, accountant, or another intended reader to understand how the conclusion was developed. Tax and legal professionals determine the filing requirements and how the appraisal will be used. The appraiser’s role is to provide an independent, well-supported opinion of value that addresses the correct property, ownership interest, effective date, and intended use.
The Details That Give an Appraisal Credibility
Beyond who prepares the appraisal and when, the IRS specifies what the report itself must contain. Missing or inadequate elements are one of the most common reasons appraisals fail IRS review, and they are also among the most preventable. A qualified appraisal must include a description of the property sufficient to identify it, the date of the appraisal and the effective date of the value opinion, the purpose and intended use of the appraisal, the definition of value being applied, the appraiser’s qualifications and declaration of independence, the methods and approaches used and the reasoning behind the value conclusion, and the appraiser’s signature and certification.
Each of those elements has to be present and substantive. A brief mention of methodology without explanation does not satisfy the requirement. A statement of qualifications that omits the required certification language does not satisfy the requirement. An appraisal prepared for “estate purposes” that does not explicitly state the intended use and user in the report may not satisfy the requirement depending on how the IRS examines it.
The declaration of independence, the appraiser’s signed statement that they have no current or prospective interest in the property and that their compensation is not contingent on the value conclusion, is one of the elements most frequently handled inadequately in reports not prepared specifically for estate and tax use. Lender appraisal formats are not designed to include it. Using a lender-format report for an estate filing is a common and costly mistake.
Reconstructing the Market as It Existed
For estate tax purposes, the relevant value is typically the fair market value of the property as of the date of death, not the date the appraisal is ordered, not the date of inspection, and not the date the report is signed. That retrospective effective date introduces analytical complexity that not all appraisers are equipped to handle well.
Developing a credible retrospective value opinion requires reconstructing the market as it existed on a specific past date, identifying what comparable sales were available, what market conditions prevailed, and what a hypothetical buyer and seller would have agreed to at that moment in time. If market conditions between the date of death and the date of the appraisal have shifted materially, the appraiser cannot simply use current data and make minor adjustments. The analysis has to be anchored to the past date with evidence that existed at that time.
An appraisal that applies current market data to a retrospective effective date without adequate support for the methodology is vulnerable on examination. The IRS is experienced at identifying this gap, and opposing experts in Tax Court proceedings have made careers out of exploiting it.
When an Estate Valuation Attracts Added Attention
Not every estate appraisal is examined closely, but certain characteristics reliably attract attention. High-value properties, significant valuation discounts, unique or hard-to-compare properties, and returns where the appraised value differs substantially from assessed value or prior transaction history are all more likely to receive scrutiny.
Beyond the property characteristics, the appraisal itself can signal risk. Reports that are unusually brief for the complexity of the assignment, that rely on a small number of comparable sales without explaining why, that apply large adjustments without support, or that use a lender-format template for an estate purpose are all patterns the IRS recognizes. An examiner reviewing a return does not need to be an appraiser to identify a report that looks inadequate for the purpose it was submitted to serve.
The appraiser’s track record also matters in contested proceedings. An appraiser who regularly prepares estate and litigation appraisals, who can articulate their methodology under questioning, and whose reports consistently include the required elements presents a very different profile than one who prepared a residential lender report and added an estate certification to the cover page.
What to Confirm Before Relying on the Appraisal
The most effective protection against IRS appraisal rejection happens before the return is prepared, not after. Attorneys and CPAs who review the appraisal before it is submitted, with the specific IRS requirements in mind, catch most problems while they are still fixable.
The questions worth asking: Does the report identify a qualified appraiser as defined under the IRC and Treasury Regulations? Does it contain the required declaration of independence? Is the effective date correct, and is the methodology clearly anchored to that date? Are the required certification elements present and substantive? Is the report format appropriate for estate and tax use, or does it appear to have been adapted from a lender assignment? An appraisal that cannot answer all of those questions cleanly is worth reviewing with the appraiser before the return goes in. Most issues at this stage are correctable. Most issues discovered during an examination are not, at least not without cost, delay, and exposure that the right appraisal at the outset would have prevented entirely.
