Do I Really Need an Appraisal if the Estate Is Under $15 Million?

When it comes to estate planning, especially for those with valuable art or collectibles, the question of whether you need a formal appraisal often arises. If your estate’s gross value is below the $15 million threshold, you might wonder: Is a qualified appraisal necessary? Could you just guess or use a rough estimate? And how does this impact taxation, documentation, and compliance with IRS rules?

This post dives deep into why appraisals matter, the definition of fair market value at the date-of-death valuation, how the IRS Art Appraisal Services and the Commissioner’s Art Advisory Panel fit into this picture, and what the key IRS timelines and forms mean for your estate. We also unpack the 2026 exemption updates irrevocable trust art taxes and the implications of the 40% estate tax rate.

Understanding Fair Market Value and Date-of-Death Valuation

First, let’s define fair market value (FMV). The IRS defines FMV as “the price at which the property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or sell and both having reasonable knowledge of relevant facts.” For estate tax and income tax purposes, this valuation is pegged as of the date of death.

Date-of-death valuation matters because:

The estate tax is calculated on the fair market value of the assets on the date the owner passed away.
The beneficiary’s tax basis in inherited property is generally the FMV at death under IRC §1014(a), commonly called the stepped-up basis.
Accurate valuation is crucial to prevent potential IRS disputes and to establish correct basis for capital gains tax if the asset is later sold.

What Is a Qualified Appraisal and When Is It Required?

For estates with art, collectibles, or other unique property, IRS rules often require a qualified appraisal, especially when claiming a value that reduces estate tax or when filing on Form 706, United States Estate (and Generation-Skipping Transfer) Tax Return.

A qualified appraisal generally means:

The appraisal is conducted by a qualified appraiser who meets the IRS definition in IRS Revenue Procedure 2023-36.
The appraisal includes a detailed description of the property, the method of valuation, the date the property was valued (date of death or alternate valuation date), and the appraiser’s signed declaration under penalty of perjury.
The appraisal must be attached to the Form 706 if the value of any item or group of similar items exceeds $3,000.

Even if your estate is under $15 million (the anticipated exemption amount adjusted for inflation in 2026), a qualified appraisal is advisable if the estate holds high-value art or property, as such assets invite IRS scrutiny.

Form 706 and the Nine-Month Timeline

The IRS requires Form 706 to be filed within nine months of the decedent's death, though a irc 1411 niit six-month extension is available. This timeline can clash with the illiquid nature of art or collectibles, which may take time to appraise or sell.

This is why having a qualified appraisal under oath is vital. You cannot wait to sell the art to determine value— the estate valuation must reflect FMV at death, not at the sale date. The appraisal provides needed documentation within IRS deadlines.

IRS Art Appraisal Services Unit and the Commissioner’s Art Advisory Panel

The IRS provides resources to manage the appraisal and audit process. Two important units are:

IRS Art Appraisal Services Unit: This specialized unit is staffed with art appraisers who audit high-value estates and assess the credibility of appraisals submitted with Form 706. They may request additional info, conduct compliance checks, or refer controversial cases for further review.
Commissioner’s Art Advisory Panel: An expert panel of external appraisers the IRS consults when complex or unusually valuable art items are involved. Their independent audit opinions carry significant weight in resolving valuation disputes.

Given their scrutiny, submitting a thorough, qualified appraisal builds your case and reduces the chance of penalties or adjustments.

2026 Exemption Amounts and the 40% Estate Tax Rate

Year Estate Tax Exemption Highest Estate Tax Rate 2023 $12.92 million (inflation-adjusted) 40% 2026 (projected) $15 million (approx.) 40%

Estates under $15 million may not owe federal estate tax, but accurate reporting is still required if the estate uses any portion of the exemption or owns art. Misstating values to avoid reporting can lead to penalties.

Why You Shouldn’t Skip the Appraisal

Step-up in basis depends on appraisal: Using the IRS’s IRC §1014(a), the beneficiary’s basis in inherited property equals the date-of-death FMV. Without an appraisal, establishing this basis is impossible, complicating future sale tax calculations.
IRS scrutiny for high-value works: Art often attracts attention because pricing is subjective and volatile. The IRS may challenge undervalued appraisals, risking penalties and audit delays.
Documentation protects you: Having a qualified appraisal under oath on hand, especially one prepared shortly before or after death, supports the estate’s valuation and reduces ambiguity.
Illiquid assets pose timing challenges: Art and collectibles can be hard to price quickly. The appraisal process helps meet the nine-month Form 706 timeline without rushing a sale or guessing value.

Checklist: Steps to Take for Art/Collectibles Valuation in Estates Under $15M

Identify all art or collectibles in the estate possibly exceeding $3,000 in value.
Engage a qualified appraiser early — select one familiar with IRS requirements and your asset type.
Ensure the appraisal report includes a declaration under oath, details on methodology, and is dated near the date of death.
Keep documentation organized for Form 706 submission, even if total estate value is below the exemption.
Consult with your estate tax CPA or attorney to confirm reporting requirements and deadlines.

Final Thoughts: Is a Qualified Appraisal Always Necessary?

Technically, estates below the federal exemption threshold do not owe estate tax and might not be required to file Form 706, depending on the state and the decedent’s overall assets. However, when valuable art or collectibles are involved—even in smaller estates—qualified appraisals serve as your strongest defense against IRS challenges.

Skipping it could leave beneficiaries exposed to:

Uncertain basis that complicates future gains calculations and taxes
Potential audits that delay estate settlement
Penalties for misreporting or underreporting value

Remember, an appraisal aligns your estate documents with IRS expectations, enabling smooth administration and compliance.
