How to Properly Value a Vehicle for an Estate or Probate

Why Estate Vehicle Valuations Matter

When someone passes away, their vehicles become part of the estate and must be properly valued for probate, tax reporting, and distribution among beneficiaries. Getting this wrong can trigger IRS audits, create disputes among heirs, and expose the executor to personal liability. For standard vehicles, NADA values may suffice — but for anything beyond ordinary, a certified appraisal is essential.

When Certified Appraisals Are Required

• Classic or collector vehicles: A classic car collection can be the most valuable asset in an estate. Book values are meaningless for these vehicles.
• Charitable vehicle donations over $5,000: IRS Section 170 requires a qualified appraisal for tax deductions on donated vehicles exceeding $5,000
• Contested estates: When beneficiaries disagree about vehicle values, a certified appraisal provides an objective, defensible number
• Estate tax returns (Form 706): Estates exceeding the federal exemption need professional valuations for all significant assets
• Motorcycles, RVs, and specialty vehicles: Standard book values rarely reflect true market value for motorcycles and specialty vehicles

Date-of-Death Valuations

The IRS requires that estate assets be valued as of the date of death (or the alternate valuation date six months later). An ASCAA-certified appraiser can produce retrospective valuations using market data from the relevant date — auction results, dealer listings, and comparable sales that were active at that time.

Executor Responsibilities

As executor, you're responsible for accurately inventorying and valuing estate assets. If you undervalue a vehicle and the IRS challenges it, the estate (and potentially you personally) faces penalties and additional tax liability. If you overvalue a vehicle, beneficiaries receiving it may pay more than necessary in estate tax. A certified appraisal documents your due diligence.
