Understanding the Context: Qualified Appraisals Under Oath and Form 706
One of the most important elements for estate tax returns involving art is the qualified appraisal. The IRS requires that any artwork valued over $3,000 submitted with Form 706 (U.S. Estate Tax Return) have a qualified appraisal performed by a “qualified appraiser” as defined by IRS rules.
A qualified appraisal is not just a market opinion—it must be a thorough, written, and signed valuation under oath, reflecting the fair market value of the artwork as of the date of death. This means valuing the artwork based on what a willing buyer would pay a willing seller in an arm’s length transaction on the exact date the decedent died.
Collin Kane CPA’s expertise includes guiding clients through the detailed documentation process and working with appraisers to ensure compliance with IRS criteria. This also involves coordinating with the IRS Art Appraisal Services unit when needed, which serves as an important resource for reviewing appraisals.
IRS Art Appraisal Services Unit and the Commissioner's Art Advisory Panel
The IRS Art Appraisal Services unit conducts reviews of appraisals submitted with estate tax returns, focusing on verifying fairness and adherence to IRS standards. This can result in lengthy audits if documentation is incomplete or appraisal methodology is challenged.
Complicating matters further, the IRS Commissioner's Art Advisory Panel is a group of independent art experts who consult with the IRS to review disputed art valuations for very high-value estates. Their opinions carry significant weight in valuation disputes.
Having a knowledgeable CPA like Collin Kane, who understands the IRS’s expectations and the technical appraisal process, can reduce audit risk as well as prepare executors and families for potential IRS challenges.
Fair Market Value and Date-of-Death Valuation Challenges
Valuing artwork at the date of death is notoriously difficult for several reasons:
- Illiquidity: Unlike stocks or bonds, art does not have a public market price updated daily.
- Subjectivity: Valuations can vary widely depending on market conditions, provenance, and expert opinion.
- Timing: The date-of-death value is a snapshot in time—value fluctuations after death or shortly before do not directly impact the valuation.
Kane Tax & Accounting understands these nuances and leverages real-world data, historical auction prices, and expert appraiser collaboration to develop defensible valuation claims. This includes:
- Ensuring appraisers provide a detailed rationale in their reports
- Documenting comparable sales and market conditions around the date of death
- Supplementing appraisal reports with supporting evidence suitable for IRS review
Documentation Is Key for IRS Scrutiny
IRS examiners scrutinize estate tax returns on multiple fronts:
- Is the appraisal qualified and compliant with IRS criteria?
- Are the appraisal assumptions supported by market evidence?
- Is there a clear linkage between the valuation method and the actual piece?
- Are illiquid assets properly valued considering the lack of frequent transactions?
Kane’s approach focuses heavily on proper documentation to create a robust, transparent valuation package that maximizes defensibility. This reduces the probability of adjustments and penalties resulting from IRS audits.
Navigating the 2026 Exemption Amounts and 40% Estate Tax Rate
The coming tax year 2026 is notable because substantial changes take effect regarding estate tax exemptions and rates:
Year Estate Tax Exemption Top Estate Tax Rate 2023-2025 Up to $12.92 million (per individual) Up to 40% Starting 2026 Approximately $5.49 million (per individual)* Up to 40%*Exact exemption figures are adjusted annually for inflation.
This sharp reduction in exemption amounts combined with the consistent 40% top estate tax rate means many estates that previously owed no tax will now face significant estate taxes. This development raises the stakes for accurate valuations and strategic estate planning.
Kane Tax & Accounting consults estates on:

- Anticipating tax liability based on these new exemption thresholds
- Estate liquidity strategies to cover the 40% tax rate on illiquid assets like art
- Proper Form 706 preparation within the IRS-prescribed nine-month filing window
Form 706 Timeline and Payment Challenges for Illiquid Art
The IRS requires Form 706 to be filed within nine months of the decedent’s date of death with possible six-month extensions. This deadline often presents risky pressure on estates holding illiquid artworks, which can be difficult to appraise and sell quickly for cash to pay estate taxes.
Kane Tax & Accounting particularly shines in helping clients manage this tension by:
- Coordinating qualified appraisals promptly to meet Form 706 filing deadlines
- Advising on installment agreements or Alternative Valuation Dates under IRC §2032
- Developing cash-flow strategies to bridge the gap between tax payment deadlines and eventual sale or liquidation of artworks
- Reviewing tax elections that might reduce liquidity pressure without increasing audit risk
