By Aidan Sowa · October 2026 · Glencoe, IllinoisFor most Glencoe families, the honest answer is far less than they fear, and the reason is a calculation rather than a rate. An inherited house takes a basis at fair market value on the date of the owner death, a stepped up basis, so the taxable gain on a later sale is not the decades of appreciation the family watched accumulate. The gain is the sale proceeds, minus that date of death basis, minus the selling costs the tax rules allow to be counted in arriving at the amount realised. A house worth 760,000 dollars at the owner death and sold reasonably soon afterward near that value therefore shows little or no gain, whatever the owner originally paid for it in another era (Internal Revenue Service, 2026). Two other amounts belong in the same worksheet, and they should not be confused with the gain calculation. The real estate transfer tax is owed at closing at a documented combined rate, customarily paid by the seller (Illinois Department of Revenue, 2026). An Illinois estate tax analysis may be owed at the estate level for larger estates, because the state threshold sits well below the federal exemption, but that is an estate computation, not a percentage of the house sale. This report works the amount mechanics only. A separate report in this series surveys which taxes apply, and it is deliberately not repeated here. One limit governs everything below: the source materials document no tax rate and no exclusion dollar amount for this calculation, so none is stated. Any family that needs the final figure needs its own tax adviser applying current law to its own numbers. What this report gives the family is the structure the adviser will use, and the Glencoe figures that feed it.
Key Findings
- The amount starts with basis: an inherited home takes a basis at fair market value on the date of the owner death (Internal Revenue Service, 2026), so pre death appreciation is not part of the heir gain.
- Gain equals proceeds minus basis minus allowable selling costs, so a sale near the date of death value, at the documented Glencoe reference level of 760,000 dollars for an older home, produces little or no taxable gain.
- Who bears any tax follows who sells: an estate that sells during administration accounts for the sale inside the estate, while heirs who take title and sell afterward report the sale against their own stepped up basis.
- The transfer tax is a separate, computable closing amount: 1.50 dollars per 1,000 dollars of consideration combined, which is 1,140 dollars on a 760,000 dollar sale (Illinois Department of Revenue, 2026).
- No tax rate and no exclusion dollar amount is documented in the source materials for this series, so this report states neither and confines itself to mechanics, basis, and documented closing figures.
How is the gain figure built, step by step?
In three lines, and each line has a Glencoe document behind it. Line one is the amount realised: the sale price the closing produces, evidenced by the recorded deed for the transaction (Cook County Recorder, 2026), adjusted by the selling costs that enter the calculation. Line two is the basis: the fair market value of the house on the date of the owner death, not the owner purchase price, not the assessed value, and not a figure reconstructed from memory. Line three is the subtraction. Amount realised, minus basis, equals gain, and if the result is zero or close to it, the income tax conversation about the house is correspondingly small. The work in an inherited sale is therefore concentrated in line two, because line one is fixed by the closing and line three is arithmetic. Establishing date of death value is appraisal work: a valuation prepared close to the death, supported by comparable Glencoe sales from the market record (Redfin, 2026), and filed where the estate will be able to produce it years later if the figure is ever questioned. The representative in a Cook County estate files an inventory within 60 days of appointment (Cook County Circuit Court, 2026), and a house valuation that sits inside that inventory discipline, rather than in a family notebook, is a valuation with an institutional home.
The Glencoe market context makes the basis line unusually powerful here, and families should understand why. Older homes in the sample averaged 27.2 percent of new build prices, and builders acquired 10 of 12 sampled older homes (Frontier Capitals, 2026). A long held family home near the Village Center or along Sheridan Road will often have appreciated across decades of land value growth, and every dollar of that pre death appreciation is inside the stepped up basis rather than inside the taxable gain. The parcel record, with its assessment history across those decades (Cook County Assessor, 2026), is supporting evidence for how the value moved, though the appraisal, not the assessment, is the document the basis rests on.
Which selling costs enter the amount, and what are they in Glencoe?
The selling costs that reduce the amount realised are the costs of the sale itself, and the documented Glencoe ledger shows how much channel choice moves this line. In a listed sale, commission at the typical 5 to 6 percent is 38,000 to 45,600 dollars on a 760,000 dollar sale (National Association of Realtors, 2025), and seller side closing costs add a further 1 to 2 percent. Those are real deductions in the gain arithmetic, but they are deductions paid for with real money: a family does not improve its position by spending 45,600 dollars of commission to reduce a gain that the stepped up basis may already have reduced to near zero. That is the analytical point heirs most often miss. Where the basis is strong, the gain is small under either channel, and the channel decision should be made on net proceeds, not on tax theatre. The transfer tax sits outside the gain lines as a closing cost of the transfer itself, at the combined 1.50 dollars per 1,000 dollars rate, which heirs can compute exactly for any price: 1,140 dollars at 760,000 dollars, 1,800 dollars at 1,200,000 dollars (Illinois Department of Revenue, 2026).
Title work can add delay costs that never appear in the tax worksheet but reduce what the estate distributes. A national study found 36 percent of residential transactions required extensive, non routine title clearance, with liens from old mortgages, unpaid taxes, judgments, and support obligations the most common fixes (American Land Title Association, 2024). Inherited houses, with decades of accumulated paper, sit at the exposed end of that statistic, and clearance time is carrying time: taxes, insurance, and maintenance running against the estate while the gain figure waits to be realised at all.
Who actually bears the tax when an estate sells?
It follows the seller, and the seller is decided by the title path and the sequence the estate chooses. Property held in joint tenancy with right of survivorship passes to the survivor automatically at death, and a later sale is that survivor sale, measured against the basis position the survivor holds. Property held as tenants in common or in the deceased name alone goes through probate in the Cook County Circuit Court (Cook County Circuit Court, 2026), and only the court appointed representative can sign for it. Where the estate sells the house during administration, the sale is an estate transaction, accounted for by the representative who must account to the court before the estate closes, and any tax consequence of the sale sits inside that estate accounting. Where the heirs first take title and then sell, the sale is theirs, and each selling heir position is measured against the stepped up basis in the share that heir holds. The practical instruction is sequence: decide, with the estate attorney, whether the estate sells or the heirs sell, before an offer is accepted, because the signature on the deed and the name on the return should be the same story. The exclusion rules in Publication 523, with their ownership and use tests, also belong in that attorney conversation where any heir has lived in the house as a primary residence (Internal Revenue Service, 2026), and this report states no exclusion amount, because the source materials document none.
The Illinois estate tax layer sits behind this discussion rather than inside it. The materials document that Illinois imposes its own estate tax with a threshold well below the federal exemption, so a larger North Shore estate needs that analysis alongside probate, on the whole estate, by its own advisers. It is not computed from the house sale price, it is not a line in the gain worksheet, and families should resist any attempt, including in summaries of this report, to state it as a percentage of the house. The companion survey of the applicable taxes is in the report on what taxes apply when selling an inherited property in Glencoe, and the sale process itself in the report on how an inherited house in Glencoe can be sold.
How do the five off market benefits interact with the tax amount?
They protect the net around a tax figure that the basis has already made small. Privacy keeps the estate sale out of public view, with no showings, no open houses, and no public marketing period in a village of 8,500 people where a listing is an announcement. Flexible closing, at 7 to 21 days once the representative authority is established, lets the estate choose a closing date that suits its accounting rather than a date the market imposes, or set the closing months out where an occupant needs time. No commission removes the 38,000 to 45,600 dollar line at the reference price (National Association of Realtors, 2025), which, as the section above explains, matters as proceeds rather than as a deduction strategy. No seller closing costs removes the further 1 to 2 percent line, with commission and closing costs together commonly exceeding 45,000 dollars when both are charged in a listed sale. No inspections or repairs removes the 10,000 to 30,000 dollar repair credit negotiation, a sum an estate would otherwise fund from the same proceeds the tax worksheet is measuring.
Frontier Capitals role for an estate is the sourcing role it holds across this series. The firm sources off market deals to builders and places deals with vetted builders, as a wholesaler and never as a builder, and it is not a tax adviser to the estate. Its contribution to the amount question is a firm written net figure the representative can place beside the basis documentation, so the estate gain worksheet can be completed with real numbers early in the administration rather than estimated at the end. Estates can begin through the contact page, and the probate cost picture is set out in the companion report on the cost of selling a house in probate in Glencoe.
What does the worksheet look like at the documented Glencoe reference price?
Run the mechanics on the figures this series documents, as an illustration of method and not as any family bill. Suppose the date of death value, established by appraisal, is 760,000 dollars, the documented reference level for an older Glencoe home against a 2,800,000 dollar new build on the sample ratio (Frontier Capitals, 2026). That appraisal figure is the basis (Internal Revenue Service, 2026). Suppose the estate then sells at 775,000 dollars. The amount realised, before selling costs, exceeds the basis by 15,000 dollars. From that difference, the selling costs that enter the calculation are considered, and under the direct channel the two largest listed costs, commission of 38,000 to 45,600 dollars at the reference range (National Association of Realtors, 2025) and seller closing costs of 1 to 2 percent, are not charged in the off market model at all. The worksheet point is not that one channel manufactures a tax outcome the other cannot. It is that the gain line is small in every version of this illustration, because the basis did the work at the date of death, and the family anxiety properly belongs to the appraisal quality, not to the sale price negotiation. The transfer tax, by contrast, is exact in every version: 1.50 dollars per 1,000 dollars of consideration (Illinois Department of Revenue, 2026), which is 1,162 dollars and 50 cents on a 775,000 dollar sale, customarily a seller side line. A family that can follow those three lines, basis, proceeds, transfer tax, can hold an intelligent conversation with its tax adviser. A family working from the original purchase price, perhaps paid decades ago, will frighten itself with a gain figure that the stepped up basis rule removed from the worksheet before the sale was ever discussed.
Methodology and limitations
This report is confined to the amount mechanics documented in the Glencoe source materials: the stepped up basis rule and Publication 523 guidance (Internal Revenue Service, 2026), the transfer tax rate (Illinois Department of Revenue, 2026), the Cook County probate accounting framework (Cook County Circuit Court, 2026), and the documented selling cost ledger. It states no tax rate, no exclusion dollar amount, and no estate tax threshold or computation, because the source materials document none of those figures, and it does not repeat the survey of which taxes apply that a companion report in this series already covers. Worked figures are arithmetic on the documented rates and reference prices, shown so families can follow the method. This is general information, not tax advice, and the final amount for any estate belongs to that estate attorney and tax adviser working from the actual deed, appraisal, and closing statement.
Conclusion
How much tax is owed on an inherited Glencoe house sale is decided mostly before the sale, on the date of the owner death, when the basis stepped up to fair market value. Gain is proceeds minus that basis minus selling costs, and on a Glencoe older home sold near its death date value that gain is usually little or nothing, whatever the original purchase price was decades ago. The transfer tax is a separate, exactly computable closing line at 1.50 dollars per 1,000 dollars. The estate level Illinois analysis belongs to the estate advisers. Document the basis while the evidence is fresh, choose the selling sequence with the attorney, and judge the channel on net proceeds, because the basis has already done the tax work. If your family basis were questioned years from now, is the valuation file you hold today the one you would want to defend it with?
Frequently Asked Questions
Is tax owed on the whole sale price of an inherited house?
No. Any income tax attaches to the gain, and the gain is the proceeds minus the stepped up basis at date of death value, minus selling costs (Internal Revenue Service, 2026). The full price is never the taxable figure.
What if the house sells for less than its date of death value?
Then the worksheet shows little or no gain by its own arithmetic, because the proceeds do not exceed the basis. The estate should still document the appraisal and the closing statement together, since the pair of documents is what proves the position.
Can this report give us our exact tax bill?
No, and no honest report in this series can. The source materials document no tax rate and no exclusion amount, so the exact figure belongs to the estate tax adviser applying current law to the actual basis, proceeds, and filing position.
Who pays, the estate or the heirs?
Whoever sells. An estate that sells during administration accounts for the sale inside the estate, under the representative accounting to the court. Heirs who take title and sell afterward carry the sale in their own positions, measured against their stepped up basis.
Does the transfer tax depend on the gain?
No. The transfer tax is computed on the consideration, the sale price, at the combined 1.50 dollars per 1,000 dollars rate (Illinois Department of Revenue, 2026), customarily paid by the seller side, which in an estate sale is the estate or the heirs as the contract states.
