The amount is computed, not guessed, and the computation has a documented spine. The federal side starts from the basis rule the record states plainly: the basis of inherited property is generally stepped up to fair market value at the date of death (IRS, 2026). Tax, where any is owed, falls on the gain above that stepped up basis, which for an inherited Redmond house sold reasonably soon after the death is usually a modest figure, the appreciation between the date of death value and the sale price, minus the costs of selling. The state side adds the real estate excise tax, computed under state rules at the closing, at graduated rates beginning at 1.1 percent on residential sales and charged to the seller (Washington Department of Revenue, 2025). Which taxes exist at all, the catalog question, is answered in the base set's what taxes apply when selling an inherited property; this report works the amount mechanics: the basis, the gain computation, the selling costs that reduce it, and who actually writes the check. Its honest limit is that no rate schedule for any heir's personal tax situation appears in the set's materials, so the final dollar figure belongs to the heir's tax advisor running these documented inputs against the heir's own return.
That limit deserves emphasis because the question invites false precision. Two heirs selling identical Redmond houses at identical prices can owe different amounts, because the gain computation is shared but the tax applied to it is personal. What the record gives every heir is the machinery: a stepped up basis established by a date of death valuation, a gain equal to the price minus that basis and minus the documented costs of the sale, an excise tax computed at the table by the title company, and a sale file that proves every input. An heir who assembles those four things can obtain an exact answer from a tax professional in one meeting. An heir who skips the valuation will spend years being unable to prove the first input, which is the expensive way to save a small fee.
Key Findings
- Basis steps up to fair market value at the date of death, so taxable gain is measured from that value, not from what the deceased paid (IRS, 2026).
- The gain is price minus stepped up basis minus selling costs; the route's cost stack therefore changes the tax as well as the net.
- The state excise tax is computed at closing under graduated rates from 1.1 percent on residential sales, seller paid (Washington Department of Revenue, 2025).
- A prompt sale near the date of death value produces a small gain almost by construction, which is a documented argument for the direct route's calendar.
- The date of death valuation, engaged early, is the single document the entire computation stands on.
Work the computation on Redmond numbers?
Take an inherited Education Hill ranch whose date of death valuation establishes 850,000 dollars, a plausible figure in a ZIP code where the study's older ranch near a 2,200,000 dollar new build changed hands around 763,000 dollars and stronger lots support more (Frontier Capitals, 2026). The heirs sell within the year at 875,000 dollars. The gross gain over basis is 25,000 dollars. Now the selling costs enter, and they enter as subtractions from the amount realized: on the listed route, the commission of 45,000 to 54,000 dollars that a sale of this size carries at the typical 5 to 6 percent (National Association of Realtors, 2025), plus seller closing costs, would exceed the gross gain entirely, leaving no taxable gain at all and a smaller inheritance besides. On the direct route, where the commission and seller cost stack are removed by the structure, the costs subtracted are far smaller and a modest gain may remain. The paradox is instructive and worth stating plainly: the expensive route can produce the smaller tax bill by destroying more value than the tax would have taken. Heirs should optimize the net, never the tax line, and the route comparison in this series exists to keep that ordering straight.
The excise tax runs on its own track, independent of gain. It is calculated by the title company under the state department of revenue's rates and calculation rules (Washington State Department of Revenue, 2026), graduated from 1.1 percent on residential sales (Washington Department of Revenue, 2025), and it is owed on the sale whether the heirs gained, broke even, or lost against the stepped up basis. On an 875,000 dollar sale the excise is a real but bounded line, visible on the settlement statement, and identical in character across routes. The federal side, by contrast, cannot be read off the statement: it is computed on the heir's or the estate's return from the documented inputs, under the framework the Service's guidance on selling a residence describes (Internal Revenue Service, 2026), including the exclusion rules whose ownership and use tests an inherited house sold by a non resident heir will generally approach differently from an owner occupant's sale. That difference is exactly the kind of determination the heir's tax advisor exists to make from the actual facts.
Value evidence feeds both tracks. The date of death valuation fixes the basis; the county's land versus improvement assessment split (King County Assessor, 2026) corroborates where the value sat at that date; and the recorded sale (King County Recorder, 2026) fixes the price. In 98052, where new construction sells between 1,800,000 and 2,800,000 dollars (Redfin, 2026), an inherited lot's appreciation between death and sale can be brisk, which is the practical argument for selling promptly and documenting the date of death figure professionally: the stepped up basis is a shield whose size is set once, early, and provable only if someone wrote it down at the time.
Two companion questions frame the amount from either side, and heirs do well to hold all three together. The first is whether the sale needs a probate at all to be taxable in this way, and it does not: the basis rule attaches to the inheritance however the title traveled, as whether an inherited house can be sold without probate explains on the authority side. The second is what the sale itself costs before tax enters, because selling costs are both a subtraction in the gain computation and a claim on the proceeds, and they are itemized for the probate setting in how much it costs to sell a house in probate. An heir who reads the three reports together holds the complete documented picture: the authority to sell, the cost of selling, and the tax on what the selling produces.
Who owes the tax, the estate or the heir?
The record documents the computation rather than a roster of taxpayers, and the honest answer is structural: the sale's proceeds flow to the estate or the heir according to how the property was held and administered, and the tax follows the party the law treats as the seller in that structure, a determination the estate's attorney and the heir's tax advisor make from the actual documents. What this report can document is the machinery that does not vary: the excise is settled at the closing table from the proceeds, whoever the seller is; the gain is computed against the stepped up basis (IRS, 2026), whoever reports it; and the sale file, valuation, statement, deed, is the evidence every version of the answer requires. Heirs who hold the property outside probate, through a trust or survivorship, will find the same computation waiting, because the basis rule attaches to the inheritance rather than to the probate.
One documented interaction deserves its own warning. The longer the interval between the death and the sale, the more the computation depends on the quality of the date of death evidence, and the larger the appreciation component in a market like this one can grow. An heir who delays the sale for a year while debating route and repairs is not deferring the tax question; that heir is enlarging the gain term and weakening the basis proof simultaneously. The direct route's 7 to 21 day calendar, exercised once authority exists, keeps the sale price close to the stepped up basis almost mechanically, which is why prompt inherited sales so often produce the anticlimactic tax answer heirs hope for: a small gain, a documented excise line, and nothing else of consequence.
What should the heir do before the sale to protect the computation?
Engage the date of death valuation first, before the offers, because every later figure is measured from it and because retrospectively manufactured valuations are the weakest documents in any tax file. Appraise the property as of the date of death, keep the appraisal with the estate's records, and let the sale's own evidence, the county split, the recorded comparables, the competing written bids, corroborate it. Sell through the structure whose costs are documented and minimal, since selling costs are a term in the gain computation and an heir should be able to prove every dollar of them from the settlement statement rather than reconstruct them from memory. Keep the statement itself permanently: it is the sale's own tax return in miniature.
Finally, put the computation in front of a tax professional with the file complete, and do it before the closing rather than at filing season. The questions that remain after the documented machinery, how the gain is characterized on the heir's return, how the exclusion framework in the Service's selling guidance (Internal Revenue Service, 2025) applies to the heir's own residence history and use, and how the estate's and the heir's filings divide the reporting, are personal tax determinations this record deliberately does not make. They are inexpensive questions with a complete file and surprisingly expensive ones without it, which is the entire practical content of this report's answer: the amount owed is knowable, early, to the dollar, for heirs who assemble the four documented inputs while they are still cheap.
What do sellers keep when a Redmond sale stays off market?
An heir selling off market keeps the family's tax affairs as private as its grief: the basis, the gain, and the proceeds exist inside the closing file and the heir's own returns, never in a listing's public trail. The neighborhood learns a house sold. It does not learn what the deceased paid in 1987, what the step up forgave, or what the heirs netted, and that discretion is part of what the route is for.
The calendar is kept in its tax significant form: a closing in 7 to 21 days once authority exists keeps the sale price near the date of death value, mechanically minimizing the appreciation the gain is computed on. The commission is kept as proceeds rather than as a selling cost, 45,000 to 54,000 dollars on a 900,000 dollar scale sale that the direct structure never spends, enlarging the inheritance by the full amount instead of converting part of it into a deduction nobody needed. The seller closing costs are kept alongside, the 1 to 2 percent that completes the combined 54,000 to 72,000 dollar burden. The repair money is kept as well, since pre sale repairs are the heir's own cash spent to enlarge a price the gain computation would then measure against the same stepped up basis.
The series disclosure is set out here in full, as in every other report. Frontier Capitals sources off market homes to builders as a wholesaler; it is not a builder, a tax advisor, or the estate's attorney, and nothing in this report is tax advice for any individual heir. Its contribution is the documented machinery and a sale whose every input, price, costs, dates, is provable from the file it leaves behind, which is the raw material from which real tax advice is made.
Methodology and limitations
This report draws on the Redmond study sample of 36 older homes in 98052, 13 acquired by builders, the set's inherited property grounding, principally the stepped up basis rule and the probate authority structure, and the tax, county, and market sources below. The computation it describes is the documented one: basis at date of death value, gain as price minus basis minus selling costs, excise computed at closing under state graduated rates.
No heir's personal rate, filing status, exclusion eligibility, or final liability is documented or computed here, because those depend on facts outside the record: the heir's own tax situation, the property's use after inheritance, and the structure through which it was held. The Internal Revenue Service guidance cited frames those determinations; the heir's tax advisor makes them. This report documents the inputs, the order of operations, and the file that makes the answer provable.
Conclusion
The tax owed when selling an inherited house in Redmond is the product of a documented computation: a basis stepped up to the date of death value, a gain measured from that basis to the sale price with the selling costs subtracted, and a state excise tax computed at the closing under graduated rates from 1.1 percent. Sold promptly, at a price near the stepped up basis, through the route whose costs enlarge the inheritance rather than the deduction, the amount is usually the smallest number in the transaction. Heirs who want the sale side of the computation assembled against the study sample can call 401-219-4207 or email [email protected] for a confidential review. If the entire tax answer stands on one valuation made near the date of death, when should that valuation be ordered?
Frequently Asked Questions
Is the whole sale price taxed as income to the heir?
No, and the basis rule is the reason: tax falls on the gain, the amount by which the price exceeds the stepped up basis and the selling costs combined (IRS, 2026). The price itself is mostly a return of the basis the law granted at the date of death. Heirs who fear a tax on the full proceeds are imagining a system the documented rule does not describe. The excise tax, by contrast, is computed on the sale under state rules (Washington State Department of Revenue, 2026) regardless of gain, and it is the one figure in the transaction that behaves the way the fear imagines, bounded, visible, and settled at the table.
What if the house sells for less than the date of death value?
Then the gain computation returns no gain, and the documented machinery has done its work in the heir's favor: the stepped up basis absorbed the decline. Whether a loss in that posture has any use on the heir's return is a personal tax determination for the heir's advisor, outside this record. The practical lesson is that the basis is a shield in both directions, which is why establishing it accurately, neither inflated nor neglected, is worth the appraisal fee in every scenario.
Does the heir owe the deceased's old low basis any respect at all?
None for this computation. The documented rule replaces the deceased's basis with the fair market value at the date of death (IRS, 2026), which is why the decades of appreciation inside a long held Redmond home, purchased when Education Hill lots cost a fraction of their current documented values, do not follow the heir into the sale. The deceased's purchase price survives only as family history. The heir's computation begins at the date of death, and the valuation that fixes that starting point is the most valuable document in the file.
When is the excise tax actually paid?
At the closing, from the proceeds, as part of the settlement the title company administers, under the state department of revenue's rates and calculation rules (Washington State Department of Revenue, 2026). The heir does not file for it separately or discover it later; it is a line on the statement, computed on the price, at graduated rates beginning at 1.1 percent for residential sales and charged to the seller side in Washington (Washington Department of Revenue, 2025). Its predictability is its virtue: of all the figures in an inherited sale, it is the one that can be known to the dollar before the contract is signed.
Should heirs delay selling to improve their tax position?
Delay enlarges the gain term in this market rather than improving anything documented: the basis is fixed at the date of death, while the price of a 98052 lot follows new construction economics upward at its own pace, and the interval weakens the valuation evidence the basis depends on. No timing advantage appears anywhere in the record's documented machinery. Heirs sometimes delay for family reasons that have nothing to do with tax, which is their right, but they should not dress the delay as tax strategy, because the arithmetic in this report runs the other way on every term.
