Being named the executor of a will is an honor — but it is also a significant legal responsibility. One of the most critical and often most difficult tasks you will face is valuing the estate's assets.
An accurate valuation is the foundation for calculating inheritance taxes, ensuring fair distribution among beneficiaries, and settling debts. However, many executors fall into common traps that lead to legal disputes, IRS audits, or financial loss for the heirs.
If you are currently navigating the probate process in Washington State, here are five valuation mistakes you cannot afford to make.
One of the most common mistakes is relying on Zillow estimates for real estate or eBay listings for collectibles. While these tools give a general idea of market trends, they do not hold up in probate court or with tax authorities.
Underestimating an asset can lead to tax penalties for underpayment, while overestimating can result in the estate paying unnecessary taxes — either way, heirs lose.
Hire certified professionals. For real property, get a formal appraisal from a licensed residential appraiser. For unique items like jewelry, fine art, or rare coins, seek out specialists who provide written, USPAP-compliant valuation reports.
In the eyes of the law, the value of an estate is determined by its Fair Market Value on the exact date of the decedent's passing. Many executors wait several months to begin the valuation process and use the current market value — a costly error.
If the stock market drops or the real estate market fluctuates in those months, the Date of Death value will be different from today's value — leading to incorrect tax filings and potential IRS penalties.
Immediately document the value of bank accounts and investment portfolios as they stood on the date of death. For real property, ensure the appraiser provides a retrospective appraisal that reflects the value on that specific date — not today's value.
Executors often remember the "big" things — the house, the car, the bank account. However, modern estates often include complex assets that are easily overlooked.
- Digital Assets: Cryptocurrency wallets, monetized YouTube channels, or valuable domain names.
- Intellectual Property: Royalties from books, music, patents, or licensing agreements.
- Business Interests: The Fair Market Value of a closely-held business or partnership stake.
Overlooking these assets can lead to an incomplete probate filing, which may require reopening the estate later — at significant legal cost and family conflict.
Work with a forensic accountant or estate attorney to conduct a comprehensive asset inventory before filing. Don't assume an asset has no value without professional verification.
The Step-Up in Basis is one of the most powerful tax benefits for heirs. When a beneficiary inherits an asset, their cost basis for capital gains purposes is reset to the Fair Market Value on the date of the decedent's death.
If you provide an inaccurately low valuation to "save" on estate taxes, you may inadvertently saddle the beneficiaries with a massive capital gains tax bill when they eventually sell the asset — often far exceeding any estate tax savings.
Work with a CPA to balance the immediate needs of the estate tax return (Form 706) with the long-term tax implications for heirs. A certified Date of Death appraisal documents the accurate step-up value that protects heirs at sale.
Valuation is not just about what an item is — it's about what condition it's in at the time of death. An executor might list a vintage car at its book value, but if the engine is seized and the interior is damaged, that value is incorrect.
Beneficiaries may accuse the executor of mismanagement or "selling low" if the eventual sale price is significantly lower than the listed probate value — creating legal exposure for the executor personally.
Take high-quality photographs and video of all physical property — real estate, vehicles, furniture, and valuables — immediately after death. This creates a timestamped record of condition that justifies the appraised value and protects you from later disputes.
