Estate Tax Lien Rules: Duration, Priority, and Discharge

A federal estate tax lien is an automatic claim the government holds against everything a person owned at death whenever the estate is large enough to require a Form 706 estate tax return. It arises by operation of law at the moment of death, lasts 10 years, and stays attached to estate property until the tax is paid or the IRS issues a discharge.¹ For deaths in 2026, only estates exceeding $15 million trigger the filing requirement, so most families never deal with one.² When it does apply, it can hold up property sales, title transfers, and distributions to heirs for months or years.

When the Lien Applies

Nobody files paperwork to create this lien. It appears automatically at the date of death whenever the gross estate is large enough that federal law requires a Form 706.³ The IRS does not record it in county land records or send anyone a notice, which is why practitioners call it a “silent lien.” It’s enforceable against the property from day one even though a buyer, lender, or heir may have no idea it exists.

For a 2026 death, the exclusion is $15,000,000 per person.² Estates below the threshold owe no federal estate tax, no Form 706 is required, and no federal lien attaches. Married couples can effectively double the exclusion to $30 million through portability, where the survivor claims the deceased spouse’s unused amount. Above the exclusion, the estate tax rate reaches 40%, but the lien itself covers the full gross estate value, not just the taxable portion.

What Property the Lien Reaches

The lien attaches to every asset in the decedent’s gross estate for federal tax purposes.¹ Real estate, bank accounts, and investments are the obvious ones. It also covers assets that never pass through probate: life insurance paid to a named beneficiary, jointly owned property that transfers by survivorship, retirement accounts, and property held in a revocable trust.

This is where heirs get blindsided. An adult child who inherits a house through a transfer-on-death deed often assumes the property is clean because it bypassed probate. It isn’t. The lien follows the asset no matter how title passes, and it stays with the property even after it lands in the new owner’s hands.¹ Property used to pay legitimate administration expenses and estate debts is freed from the lien once those payments are made, provided a court with jurisdiction approved them.

How Long the Lien Lasts

The lien runs for 10 years from the date of death.¹ It ends earlier only if the estate tax is paid in full or the IRS issues a discharge. Otherwise it simply expires at the 10-year mark. The clock is fixed to the death date; audits, amended returns, and disputes do not restart or extend it.

Personal Liability for Heirs and Executors

The lien is a claim on property, but the same law creates personal liability for people who receive or control estate assets. If the estate tax goes unpaid, anyone who held gross-estate property at the date of death can be pursued personally for the tax, up to the value of what they received.¹ That reaches surviving spouses, trustees, beneficiaries, and surviving joint tenants.

Executors carry a separate exposure. Under federal law, a representative who distributes estate assets before satisfying the government’s claim is personally liable for the tax to the extent of those distributions.⁴ The prudent practice is to hold back enough to cover the estimated tax plus a cushion for adjustments until the IRS issues a closing letter confirming the return has been accepted.

Selling Inherited Real Estate Before the Tax Is Settled

The lien creates the sharpest problems when heirs try to sell inherited real estate. Because it does not appear in county records, title insurance companies check for it independently. If the seller recently inherited property from someone whose estate may have required a Form 706, the title company will usually refuse to issue clean title insurance until the lien is resolved.

Three paths clear the way for closing: the estate pays the tax in full and the IRS issues a discharge; the executor files Form 4422 and arranges for escrow of the sale proceeds; or 10 years have passed since the date of death and the lien has expired.⁵ Some title companies will accept an indemnity from the seller and proceed before the IRS discharge is in hand, but that’s a case-by-case decision driven by the insurer’s risk tolerance and the facts of the estate.

The timing is usually the frustration. Under the current Form 4422 procedure, when the IRS has not finished reviewing the estate tax return, it typically requires the net sale proceeds to be deposited in escrow or paid directly to the IRS. Those funds are released after the IRS issues an estate tax closing letter or determines the return will not be audited. The agency does not publish estimated processing times.

Getting the Lien Discharged or Subordinated

Paying the estate tax in full is the cleanest way out. Once payment is confirmed, the IRS can issue a certificate of discharge under its authority to release property from estate and gift tax liens.⁶ Discharge is also available when the IRS determines the liability has been “fully satisfied or provided for,” which can include posting alternative security.

When a specific asset needs to be sold before the estate tax is finished, the executor, beneficiary, or buyer can file Form 4422 to ask the IRS to release the lien on just that piece of property.⁵ The IRS can also subordinate the lien rather than discharge it, making another creditor senior to the government. Subordination is usually granted when the IRS believes the estate will ultimately pay more tax as a result, or when adequate substitute security is offered.⁶

An estate tax closing letter is the IRS’s confirmation that a Form 706 has been accepted as filed or that any examination is complete. The closing letter does not formally discharge the lien on its own, but executors and title companies rely on it as the practical signal that the liability is final.⁷

Priority Over Other Claims

The estate tax lien generally outranks competing claims. Because it arises automatically without recording, it can take priority over liens that creditors would otherwise expect to come first. Two categories of transferees, however, take property free of it:

A purchaser who pays full and adequate consideration, where the sale is valid under local law against later buyers without actual notice of the lien.⁸
A holder of a security interest who has a contractual interest in the property to secure a debt and has parted with money or money’s worth.⁸

When property passes to a protected party, the lien detaches from that asset and reattaches to whatever other property the transferee holds. The government’s security is preserved; it simply shifts. Mechanic’s liens and certain other interests protected even against filed federal tax liens also defeat the estate tax lien.¹

Filing Deadline and Late Payment Consequences

Form 706 is due nine months after the date of death.⁹ The executor can request an automatic six-month extension on Form 4768, pushing the filing deadline to 15 months.¹⁰ An extension to file is not an extension to pay. Absent a separate payment extension, the tax is still due at nine months.

The failure-to-pay penalty is 0.5% of the unpaid tax per month, capped at 25%, with interest running on the unpaid balance from the original due date.¹¹ Separately, if the IRS determines that the return significantly undervalued assets, a 20% accuracy-related penalty applies to the resulting underpayment.¹² These penalties compound the tax already secured by the lien.

State Estate Tax Liens Are Separate

About a dozen states and the District of Columbia impose their own estate or inheritance taxes, often with far lower exemption thresholds than the federal $15 million. Several of these states create their own automatic liens on estate property at death, with their own durations and discharge procedures. An estate that falls below the federal filing threshold can still face a state-level lien if it exceeds the state’s lower exemption. If any estate property sits in one of those states, check the state rules alongside the federal ones.
