Selling an Inherited House in Pennsylvania: Taxes You Need to Understand Before You Close

You are sitting at the closing table, ready to sign, and the title company attorney slides over a sheet showing an escrow holdback for the inheritance tax — sometimes calculated on the entire value of the estate, not just the house. The real estate agent said this might happen. Nobody told you it could be this large, or that you might be on the hook for two separate capital gains calculations — one for the IRS and one for Pennsylvania — that produce completely different numbers.

Selling an inherited house in Pennsylvania is more complicated than selling your own home. There are four interlocking issues that every executor or heir needs to understand before they list the property, sign a listing agreement, or accept an offer.

Issue One: The Inheritance Tax Lien on the Property

Pennsylvania inheritance tax creates an automatic, statutory lien on all estate property at the moment of the decedent's death. This is not a lien that gets recorded at the courthouse and shows up in a title search. It attaches by operation of law regardless of whether anyone has filed anything.

What this means in practice: the property cannot transfer with clear title to a buyer until the Commonwealth is satisfied that the inheritance tax either has been paid or is otherwise accounted for. Title insurance companies understand this, and they will not insure the buyer's title without resolution.

The cleanest path is to have paid the inheritance tax in full and received the Department of Revenue's official tax clearance certificate before the closing table. When you present that certificate to the title company, they can confirm that the statutory lien has been extinguished and insure the title without any reservation.

If the inheritance tax has not been fully paid and the clearance certificate has not been issued, the title company will require the estate to hold an escrow at closing. The escrow amount is the title company's protection against the outstanding lien — and it is often sized conservatively, meaning the holdback can represent a significant portion of the net sale proceeds that the estate or heirs will not receive until the Department of Revenue clears the file months later.

Issue Two: The 15-Month Safe Harbor for Valuation

Pennsylvania inheritance tax is calculated on the fair market value of the real property as of the date of death. Under normal circumstances, this requires the estate to obtain a formal appraisal from a licensed professional. The Department of Revenue rejects county property tax assessments as a proxy for fair market value — assessed values routinely diverge from actual market conditions, and the agency will challenge unsubstantiated valuations.

However, Pennsylvania recognizes a highly useful exception for estates that sell the inherited property relatively quickly. If the real estate is sold through an arm's-length transaction — a bona fide sale to an unrelated buyer at market price — within fifteen months of the decedent's date of death, the estate may use the gross sale price as the date-of-death fair market value on the REV-1500 inheritance tax return.

This is the fifteen-month safe harbor rule, and it is one of the most practically useful provisions in Pennsylvania estate law for estates that include real property.

Why this matters financially: A professional real estate appraisal costs money and time, and it may produce a value that triggers a higher inheritance tax than the estate anticipated. If the property sells within fifteen months at a price lower than what a speculative appraisal might have shown (for instance, because the estate accepted a discount for a quick sale, or because market conditions softened), the lower sale price reduces the taxable value — and with it, the inheritance tax bill.

How to use it: When the estate is preparing the REV-1500, if the property has already sold within the fifteen-month window, the executor can suspend the formal valuation on the initial return, close the sale, and then report the actual sale price as the date-of-death value when the return is finalized. An estate attorney or the Register of Wills can explain the procedural mechanics for suspending the valuation pending the sale.

The practical consequence: Estates that are "house poor" — where the real property is the primary asset and the estate has limited liquid cash to pay the inheritance tax before the closing — can often use the closing proceeds themselves to pay the outstanding inheritance tax simultaneously at closing, eliminating the lien and the need for a large escrow holdback in a single transaction.

Issue Three: The Federal Step-Up in Basis

For most inherited property, federal tax law offers a substantial benefit called the step-up in basis. When an asset is inherited, the beneficiary's cost basis for federal capital gains tax purposes is stepped up to the fair market value of the asset on the date of the decedent's death.

The practical impact is enormous. If a parent purchased a house thirty years ago for $80,000 and it was worth $420,000 on the date of death, an adult child who inherits it and immediately sells it for $420,000 has a federal capital gain of zero. Their basis was stepped up to $420,000 at the moment of inheritance, and the sale produces no taxable gain.

This is the rule that applies to most inherited real estate — property that was titled in the decedent's name alone, or that passed through the probate estate to beneficiaries.

Issue Four: Pennsylvania's Step-Up Denial for Tenants by the Entireties

Here is where Pennsylvania diverges sharply from federal law, and where surviving spouses consistently get caught.

Pennsylvania law explicitly denies a step-up in basis for property owned as tenants by the entireties — the form of joint ownership that married couples in Pennsylvania most commonly use for their marital home. When a married couple holds a home as tenants by the entireties, the surviving spouse does not get a step-up in basis for Pennsylvania personal income tax purposes when the first spouse dies.

The disparity creates a dual-basis situation that looks like this:

A married couple purchased their home in 1998 for $75,000, titling it as tenants by the entireties. At the time of the first spouse's death in 2026, the home is worth $380,000. The surviving spouse inherits the decedent's interest automatically by operation of law.

Federal capital gains calculation: The IRS steps up the basis to $380,000. The surviving spouse sells the home for $385,000. Federal capital gain: $5,000 (reduced further by the primary residence exclusion if applicable).

Pennsylvania capital gains calculation: Pennsylvania does not recognize the step-up for tenants by the entireties property. The surviving spouse's Pennsylvania basis remains at the original $75,000 purchase price, adjusted for any capital improvements made over the years. Pennsylvania capital gain on the $385,000 sale: up to $310,000 — fully taxable at the Pennsylvania personal income tax rate.

This is not a technicality. For surviving spouses who sell the marital home shortly after the first spouse's death, the Pennsylvania tax bill on what is essentially appreciated value from decades of homeownership can be substantial and completely unexpected. The federal return may show minimal or no taxable gain, while the Pennsylvania return generates a significant liability.

Calculating Your Capital Gain for Pennsylvania

Because Pennsylvania denies the step-up for tenants by the entireties, surviving spouses and their tax preparers must maintain dual-basis records:

• Federal basis: Fair market value as of the date of death (the stepped-up amount)
• Pennsylvania basis: Original purchase price plus documented capital improvements made during the period of ownership

Capital improvements — additions, renovations, replacements of structural systems — are added to the original basis and reduce the taxable gain. Routine maintenance and repairs do not qualify as basis adjustments.

The record-keeping burden falls on the surviving spouse. If the original purchase documents, closing statements, and records of capital improvements have been lost over decades of ownership, reconstructing the Pennsylvania basis requires working backward through old tax returns, bank records, contractor invoices, and property records. This is one of the strongest arguments for maintaining comprehensive property records throughout ownership — not just at the time of sale.

The Title Company Escrow: What Drives the Holdback Amount

When inheritance tax has not been fully resolved before closing, title companies typically calculate the escrow holdback based on the highest plausible tax liability — which can mean a percentage of the entire estate value, not just the real property being sold.

This happens because the title company's exposure is limited to the property they are insuring. But they do not know the full estate picture. If the inheritance tax is still in process and the estate has not yet received a clearance certificate, the title company assumes a worst-case scenario to protect itself. The result is a holdback that can far exceed what the estate ultimately owes.

For estates where real estate is the primary asset, the most effective strategy is to sequence the inheritance tax filing alongside the sale:

1. File the REV-1500 as early as possible, using the fifteen-month safe harbor to suspend the real estate valuation pending the sale.
2. At closing, use a portion of the sale proceeds to pay the outstanding inheritance tax estimate directly.
3. Submit the final tax payment to the Register of Wills.
4. Obtain the clearance certificate and release the title lien.

When this sequence is communicated to the title company in advance, and when the closing is structured to include a direct payment to the Register of Wills, escrow holdbacks can often be reduced or eliminated.

Who Owes What on the Sale

Inheritance tax and capital gains tax are distinct obligations that may fall on different parties.

The inheritance tax on the property is typically an obligation of the estate, paid by the executor out of estate funds before distributions to heirs. When the estate distributes the property directly to a beneficiary who then sells it, the tax obligation on the original transfer may still be the estate's responsibility — but the capital gains from the beneficiary's subsequent sale belong to the beneficiary.

If you inherited the property outright and you are now selling it as an individual (not as an executor), your capital gains exposure depends on your basis (stepped up at the federal level, not stepped up if tenants by the entireties) and the sale price. Consult with a Pennsylvania CPA who handles estate and fiduciary tax matters to ensure you are running both the federal and state calculations correctly before you file.
