How federal law sets an heir's basis
Federal law generally resets an inherited home's basis to its fair market value at the owner's death (IRS: gifts and inheritances; 26 U.S.C. 1014(a)(1)). If the executor elects alternate valuation under section 2032, basis follows that later valuation date instead (1014(a)(2)). Sell for more than the basis and the difference is a taxable gain. Because the rule resets basis to the value at death, it can move basis down as well as up: a home worth less at death than its owner paid takes the lower figure. A consistency rule dating from 2015 can also bind a Marysville heir: in certain cases, once the federal estate tax value of the house is finally determined, the basis the heir reports must be consistent with it.
An heir in Marysville pays no federal inheritance tax on the house; federal law taxes the estate instead, through an estate tax the executor pays. An estate tax return generally becomes necessary, for a U.S. citizen or resident who dies in 2026, only once the gross estate plus certain lifetime gifts goes over $15,000,000 (IRS estate tax). Receiving the house is generally not income to the heir, though any rent it brings in afterward is taxable (IRS Publication 525).
Community property and a married couple's Marysville home
Washington appears on the IRS list of community property states in Publication 555, and that matters when the first spouse dies. Section 1014(b)(6) of the tax code extends the date-of-death rule to the survivor's own half of community property, on the condition that at least half of the couple's whole community interest was includible in the gross estate of the spouse who died. Publication 555 puts it this way for the survivor: the total fair market value of the community property, the survivor's share included, generally becomes the basis of all of it. The same publication says the rule does not reach registered domestic partners.
So a date-of-death appraisal of a community property home may bear on the basis of the entire house, not just the half that belonged to the spouse who died. Whether the home was community or separate property (RCW 26.16.030 and RCW 26.16.010) and how the basis rules apply are questions for your tax adviser and attorney; the appraisal supplies the value, not the tax answer.
Washington's estate tax runs on its own track
Washington imposes an estate tax that is independent of the federal one (RCW 83.100.040). For deaths from January 1 through June 30, 2026, a Washington return was required once the gross estate reached $3,076,000, with rates from 10% to 35%; for deaths on or after July 1, 2026, the threshold is $3,000,000 and the rates run from 10% to 20% (RCW 83.100.020; DOR estate tax tables). Washington has no inheritance tax. When a Washington return is due and the house was not sold, the Department of Revenue asks for a certified appraisal to support its value. An estate may also elect alternate valuation on a Washington return even when no federal return is filed (DOR alternate valuation); that is a state election, and whether it has any federal effect is a question for your tax adviser.
A past date needs evidence from that time
A retrospective value rests on sales and market conditions from around the date of death, not on today's prices. The Snohomish County Assessor's figure is no substitute, because it is a property tax value tied to January 1 of the assessment year. Location matters as much as timing. Marysville's 2024–2044 Comprehensive Plan describes Pinewood as the first area the city expanded into in the 1960s, while Getchell Hill is known for Cedarcrest Golf Course and views of Puget Sound and the Olympic Mountains; a sale in one is not automatically a fair comparison for a house in the other.
What to gather for your tax adviser and the appraiser
- The date of death, and whether the executor may elect an alternate valuation date.
- The decedent's marital status and how title was held, so your adviser can weigh the community property question.
- Photos, invoices or listing records that show the home's condition at the date of death, and any changes since.
- The date and price of any sale after the death.
- Whether a federal or a Washington estate tax return is expected.
Settle the effective date and the report's purpose with your tax adviser first, then ask Eagle Home Appraisal Marysville for the scope, fee and delivery estimate in writing. The same date-of-death value may also be needed for a probate valuation or an estate appraisal.
