The amount owed is built, not guessed, and the construction has three parts. First, the home takes a stepped-up basis equal to its fair market value on the date of death, established by a date-of-death appraisal (Internal Revenue Service, 2026). Second, the taxable gain equals the eventual sale price minus that stepped-up basis and minus the selling costs, so only appreciation after the death enters the computation (Internal Revenue Service, 2026). Third, that gain is taxed federally under the sale of home rules and taxed by Connecticut as ordinary income at rates up to 6.99 percent, with no special state capital gains rate and no exclusion of its own (Connecticut Department of Revenue Services, 2025) (Internal Revenue Service, 2025). The documented Greenwich illustration shows the result at work: a 2,200,000 dollar home with a proper stepped-up basis often produces little or no capital gains tax when it is sold near the appraised value. Separately, Connecticut conveyance tax is computed on the full sale price rather than on the gain, so a bill can be owed on the transfer even in a year when the capital gains computation returns zero (Connecticut Department of Revenue Services, 2025).

Key Findings
- Gain is computed as sale price minus stepped-up basis minus selling costs, and the stepped-up basis is fair market value on the date of death (Internal Revenue Service, 2026).
- A 2,200,000 dollar Greenwich home sold near its date-of-death appraised value often produces little or no capital gains tax, because pre-death appreciation sits outside the gain (Internal Revenue Service, 2026).
- Connecticut taxes any post-death gain as ordinary income at rates up to 6.99 percent, with no special capital gains rate and no state exclusion of its own (Connecticut Department of Revenue Services, 2025).
- Conveyance tax is figured on the full sale price, not on the gain, at a state rate of 0.75 percent on the first 800,000 dollars plus a municipal tax, and it is paid by the seller (Connecticut Department of Revenue Services, 2025).
- The federal Section 121 primary residence exclusion, explained in Publication 523, can shelter gain only where a seller personally qualifies, and it never applies to a second property as an inherited sale shelter (Internal Revenue Service, 2025).
Who actually owes the tax on an inherited sale?
Obligation follows the seller of record. Where an estate sells the house during administration, the estate handles the sale and its proceeds are applied under the executor duties to pay valid debts and taxes before what remains is distributed under the will or Connecticut intestacy rules (Frontier Capitals, 2026). Where title has already passed to the heirs and the heirs sell, the heirs are the sellers and the gain computation runs on their sale. Either way, the person or entity signing the deed is the party whose tax file absorbs the transaction, which is one reason the timing of a sale relative to distribution deserves advice from a Connecticut estates attorney rather than improvisation by the family group chat.
The identity question matters because the exclusion rules are personal. Publication 523 sets out the federal sale of home framework, including the Section 121 exclusion for a qualifying primary residence (Internal Revenue Service, 2025). An heir who actually lived in the inherited Greenwich house as a primary residence for the qualifying period may have an exclusion argument an absentee heir does not. An heir who never lived there, selling a house that was the parent second property or simply a property they inherited and held, has no primary residence exclusion to apply, and the documented guidance is explicit that capital gains on a second property receive no such shelter. Each heir file must therefore be computed on its own facts, even when several heirs split one sale.
Estate level exposure sits behind the sale computation and should not be folded into it. The Connecticut estate tax exemption sits below the federal threshold, so a large Greenwich estate may owe state estate tax on the transfer of wealth itself, separately from any capital gains tax on the later sale (Frontier Capitals, 2026). Conflating the two leads heirs to double count or to miss one entirely. The sale computation in this report answers the headline narrowly: given a basis, a price, and selling costs, how much tax does the sale generate, and to whom. Heirs who have not yet settled the selling sequence itself can follow how an inherited house in this neighborhood can be sold and return to this computation once a buyer and a price are real.
How is the gain figure assembled, line by line?
Line one is the sale price, the amount the buyer actually pays for the house in central Greenwich or the southern Backcountry. Line two is the basis, and for inherited property the basis rules assign fair market value at the date of death (Internal Revenue Service, 2026). The date-of-death appraisal is the evidentiary anchor for line two, and heirs should obtain it promptly, while comparable sales near the death date are fresh and an appraiser can still inspect the property in something close to its inherited condition. An appraisal reconstructed years later costs more, convinces less, and invites the tax authorities and the heirs alike to argue.
Line three is selling costs, the expenses of the transaction itself, which reduce the amount realized or the gain depending on their character, and which the closing statement itemizes. This is where the sale route changes the tax answer. A listed sale in this market loads commissions of 4 to 6 percent and seller closing costs of 1 to 2 percent into the file, and those costs are real deductions from the economics even though heirs experience them as fees rather than as tax planning. A direct sale strips most of those costs away, which slightly raises the measured gain while substantially raising the cash the heirs keep, a trade every heir should welcome and none should mistake for a tax problem.
Subtract basis and selling costs from the price, and the remainder is the gain, the only figure the capital gains taxes touch. If the house sells for its appraised date-of-death value, the remainder is roughly the negative of the selling costs, which is why the documented 2,200,000 dollar example so often ends at little or no capital gains tax (Internal Revenue Service, 2026). If the Greenwich market lifts the house between death and sale, the remainder is that lift, and only that lift. Decades of parent appreciation, however large, never enter the form.

How do the federal and Connecticut computations differ on the same gain?
Both governments tax the same computed gain, and then their paths diverge. Federally, the gain from an inherited house sale is reported under the sale of home rules, and the Section 121 exclusion may remove part or all of it where the seller personally qualifies through residence and ownership tests described in Publication 523 (Internal Revenue Service, 2025). Heirs should note what the exclusion is not: it is not an inheritance exemption, it does not attach to the property, and it does not travel with the deed from the parent to the child. A parent who could have excluded gain had they sold during life does not bequeath that exclusion. The heir starts fresh, with a stepped-up basis as their protection instead.
Connecticut applies its own computation to the same transaction with fewer shelters. The state taxes capital gains as ordinary income, applies rates up to 6.99 percent, and provides no special capital gains rate and no exclusion of its own (Connecticut Department of Revenue Services, 2025). An heir can therefore owe Connecticut tax on a modest post-death gain in a case where the federal answer is softened by timing or by a personal exclusion. The reverse is equally possible in unusual files. Competent preparation runs both computations in parallel, on the same gain figure, and reports each to its own authority, rather than assuming the federal answer predicts the state one.
Rate application deserves one caution. Up to 6.99 percent is the documented ceiling of the state treatment, not a promise that every heir pays the ceiling rate on every dollar (Connecticut Department of Revenue Services, 2025). Individual income position decides where inside the state structure a given heir gain lands, and that individuality is precisely why this report computes the gain carefully and quotes the rate as a ceiling. Heirs who want a personal dollar estimate should hand the computed gain, the appraisal, and their own income picture to a Connecticut tax adviser, who can finish the last step that a market report properly leaves open.
Why is conveyance tax computed so differently, and how is it figured?
Conveyance tax ignores gain entirely because it is a tax on the transfer, measured by the consideration paid. The documented state structure charges 0.75 percent on the first 800,000 dollars of price, seller paid, plus a municipal tax, and state policy materials describe the rates and administration that govern its collection at recording (Connecticut Department of Revenue Services, 2025) (Connecticut Office of Policy and Management, 2026). Legislative background research on the tax confirms that its base is the sale price, so the stepped-up basis that can erase a capital gains bill has no effect on it whatsoever (Connecticut General Assembly, 2020). The documented illustration is deliberately stark: an inherited Greenwich estate selling for 4,000,000 dollars pays conveyance tax measured on 4,000,000 dollars.
Heirs budgeting a closing should therefore carry two separate tax lines that behave oppositely. The capital gains line shrinks toward zero as the sale price approaches the date-of-death appraisal. The conveyance line grows in direct proportion to the price and is owed in full on a triumphantly priced sale. In a direct sale structure, the research for this neighborhood identifies conveyance tax as the one statutory seller cost that remains after commissions and seller closing costs are removed, while noting that its handling can be negotiated between buyer and seller. Negotiation can move who writes the check, never the base on which the tax is computed, and heirs should confirm the current treatment with the closing attorney before signing, since Connecticut closings are attorney driven (State of Connecticut, 2026).
Assessment records support the file around both computations. The assessor parcel record documents the property whose value the appraisal addresses and whose transfer the conveyance tax measures, and discrepancies between the parcel record and the family understanding of the lot should be resolved before either computation is finalized (Town of Greenwich Tax Assessor, 2026).
How do the five off-market benefits interact with the tax owed?
Frontier Capitals sources off-market deals to builders and does not build, and a direct sale changes the inputs to the tax computation without changing its rules. Privacy is the first benefit: no showings and no open houses mean the family tax planning stays as private as the sale, and the transaction surfaces publicly only when the deed records. Timing flexibility is the second, and it has genuine tax significance in an inherited file. A closing in 7 to 21 days lets heirs sell close to the date-of-death value when that is advantageous, while a closing set months out with a leaseback can place the sale in the tax year and the market season the heirs and their adviser prefer, against a listed span of 60 to 120 plus days that chooses its own timing.
No commissions is the third benefit, preserving 48,000 to 72,000 dollars on a 1,200,000 dollar sale against the typical 4 to 6 percent structure (Frontier Capitals, 2026). Heirs should understand the subtle interaction: lower selling costs slightly increase the measured gain, while greatly increasing net cash, so the tax tail never wags this dog. Fourth, removing seller closing costs of 1 to 2 percent has the same character, with commissions and closing costs together normally running 6 to 8 percent, or 72,000 to 96,000 dollars at the reference price (Frontier Capitals, 2026). The conveyance tax line remains, as described, and should be confirmed and, where possible, negotiated.
Fifth, no inspections and no repairs means the estate does not spend money improving a house whose post-death appreciation is the only taxable slice anyway. Repair spending before an inherited sale is doubly unrewarded: it consumes estate cash, and to the extent it lifts the price above basis it manufactures taxable gain. Selling the house as it stands, with belongings in place where the buyer agrees, keeps the computation close to the clean appraisal comparison the stepped-up basis rules intend (Internal Revenue Service, 2026).

What worked examples show the computation honestly?
Take the documented Greenwich case first. A home appraised at 2,200,000 dollars on the date of death sells eight months later for 2,240,000 dollars in a direct sale with minimal selling costs. The gain computation subtracts the 2,200,000 dollar basis from the price, leaving roughly 40,000 dollars before selling costs, and selling costs then absorb much or all of that remainder. Federal and Connecticut capital gains taxes on what survives are correspondingly small, matching the documented guidance that such a sale often produces little or no capital gains tax (Internal Revenue Service, 2026). The conveyance tax, by contrast, is computed on the entire 2,240,000 dollars and is owed without apology.
Now stretch the interval. The same home, held while the Backcountry market rises, sells two years later for 2,600,000 dollars. The basis is still the date-of-death figure, because basis is fixed at death, so the gain before selling costs is roughly 400,000 dollars, and both tax systems now have something real to tax, Connecticut at ordinary income rates up to 6.99 percent and the federal system under its sale of home framework (Connecticut Department of Revenue Services, 2025) (Internal Revenue Service, 2025). Nothing about the heirs behavior was imprudent. Holding created the gain, and the tax follows the gain, which is why advisers ask heirs early whether they intend to sell near the appraisal or to hold as investors, since those are different tax postures wearing the same deed.
A third case completes the picture: a sale below the appraised value, which happens when a house has deteriorated or the appraisal was optimistic. The computation then produces no gain at all, and the capital gains lines are zero in both systems, while the conveyance tax remains due on whatever price was actually paid. Heirs sometimes feel a below appraisal sale wastes the stepped-up basis. In truth it simply means the market disagreed with the appraisal, and the honest response is documentation: keep the appraisal, the bids, and the closing statement together, so the file explains itself if any authority asks why the numbers moved.
Methodology and limitations
The computation method in this report follows the documented federal and Connecticut facts for this neighborhood: stepped-up basis at date-of-death fair market value with a date-of-death appraisal and Publication 551 basis treatment (Internal Revenue Service, 2026), the federal sale of home framework including Section 121 in Publication 523 (Internal Revenue Service, 2025), Connecticut capital gains treatment as ordinary income up to 6.99 percent with no state exclusion (Connecticut Department of Revenue Services, 2025), and conveyance tax on the full price under the documented state rate structure, its legislative background, and its administration (Connecticut Department of Revenue Services, 2025) (Connecticut General Assembly, 2020) (Connecticut Office of Policy and Management, 2026). Estate context, executor duties, and market figures come from the neighborhood sample research (Frontier Capitals, 2026), parcel grounding from assessor records (Town of Greenwich Tax Assessor, 2026), and closing practice from Connecticut attorney driven custom (State of Connecticut, 2026). This report deliberately computes the gain, which is the documented mechanical question, and leaves each heir final dollar liability to their own income position and adviser, because no source in this record publishes a personal rate schedule for individual heirs. This general computation is not a substitute for advice on a particular estate.
Conclusion
Tax owed on an inherited Greenwich sale equals tax on a carefully computed gain, sale price minus the stepped-up date-of-death basis and selling costs, plus a conveyance tax computed on the full price that no basis can reduce. Sold near the appraised value, the documented 2,200,000 dollar case shows the capital gains answer can be little or nothing, while the conveyance line still must be paid and the estate level questions still must be checked separately. The heirs who fare best are the ones who order the appraisal early and run the subtraction before they argue about the answer. Have you seen your inherited house gain written as three lines, price, basis, and costs, rather than as a single frightening guess?
Frequently Asked Questions
Is tax owed on the entire sale price of an inherited house?
No. Capital gains tax is owed only on the gain, which is the sale price minus the stepped-up basis at date-of-death value and minus selling costs. The tax that does touch the entire price is the Connecticut conveyance tax, which is computed on the full consideration regardless of basis.
What if the heirs never obtained a date-of-death appraisal?
The basis still exists in law, but proving it becomes harder and more contestable. Heirs should commission a retrospective appraisal from a licensed appraiser as early as possible, since the stepped-up basis figure carries the whole capital gains computation at both the federal and Connecticut level.
Does the Section 121 exclusion protect heirs automatically?
No. The exclusion in Publication 523 is personal to a seller who meets its residence and ownership conditions. An heir who lived in the house as a primary residence may qualify on their own facts. An heir who never lived there cannot borrow the deceased owner exclusion, and a second property receives no such shelter.
Who pays the tax when the estate sells before distribution?
The selling estate handles the transaction, and its proceeds are applied to valid debts and taxes under the executor duties before the remainder is distributed. When heirs sell after title passes to them, the heirs are the sellers and the tax lands on their own returns.
At exactly what rate will Connecticut tax an heir gain?
The state treats a capital gain as ordinary income, applying rates that reach 6.99 percent at the top, and it grants neither a special gains rate nor an exclusion of its own. Where a particular heir lands within that structure depends on their own income picture, which is why the final dollar figure belongs to the heir tax adviser working from the computed gain.
