Can You Disclaim a Portion of an Inheritance? (w/Examples) + FAQs

Yes, you can disclaim a portion of an inheritance. Federal law and most state laws let a beneficiary refuse part of a gift or bequest while keeping the rest, as long as the refusal meets strict rules under Internal Revenue Code Section 2518 and the applicable state disclaimer statute. A partial qualified disclaimer lets you walk away from a specific dollar amount, a fractional share, a separate asset, or even a particular interest in property without being treated as if you received the asset and then gave it away.

The problem is timing and form. The IRS treats a botched disclaimer as a taxable gift from you to the next person in line, which can trigger federal gift tax, generation-skipping transfer (GST) tax, and a loss of basis adjustments. The Treasury Regulations under §25.2518-1 through §25.2518-3 demand a written, irrevocable, unqualified refusal delivered within nine months, and partial disclaimers add their own traps around pecuniary versus fractional interests, severable property, and undivided portions.

According to the American Bar Association’s Real Property, Trust and Estate Law Section, roughly 1 in 8 estates with assets over $1 million sees at least one beneficiary execute a disclaimer, and partial disclaimers now account for a growing share as families plan around the scheduled 2026 sunset of the doubled federal estate tax exemption.

What a Partial Disclaimer of an Inheritance Means

A partial disclaimer is a written, irrevocable refusal to accept part of a gift, bequest, devise, beneficiary designation, or other transfer of property. The refused share passes to the next taker as if the disclaimant predeceased the decedent, under the rules in the Uniform Disclaimer of Property Interests Act (UDPIA) adopted by most states.

Federal law calls a valid refusal a qualified disclaimer under IRC §2518. When the refusal qualifies, the IRS does not treat the disclaimant as having made a gift. When it fails, the IRS treats the refusal as a constructive transfer from the disclaimant, and gift tax, GST tax, or income tax can apply.

A partial disclaimer is allowed when the refused interest is severable from the rest. The Treasury Regulations at §25.2518-3 define severable property as property that, if divided, leaves each part with its own complete identity, such as a specific number of shares of stock, a specific tract of land, or a fractional share of a residue.

The Core Federal Rule Under IRC §2518

Section 2518 of the Internal Revenue Code sets five strict tests that every disclaimer, partial or full, must satisfy. The refusal must be in writing, irrevocable, unqualified, delivered within nine months of the later of the transfer or the disclaimant’s 21st birthday, and the disclaimant must not have accepted any benefits from the refused interest. You may read the full statute at the Cornell Legal Information Institute version of IRC §2518.

The plain-English meaning is simple. You cannot keep the dividends from stock you plan to disclaim, you cannot live rent-free in a house you plan to disclaim, and you cannot deposit a check from the estate and later try to refuse it. The consequence of accepting any benefit is a complete loss of qualified status, which converts the refusal into a taxable gift to whoever receives the property next.

A real example helps. Marcus inherits 1,000 shares of Apple stock and $200,000 in cash from his mother. He wants the cash but wants the stock to pass to his daughter under the will’s contingent clause. If Marcus signs a written refusal of the 1,000 shares within nine months and never collects a dividend on those shares, the disclaimer is valid. If Marcus collects even one quarterly dividend on those shares, the IRS will treat the refusal as a gift from Marcus to his daughter.

A common misconception is that the nine months runs from probate or from the date assets are distributed. The clock starts on the date of death for most transfers, not the date of distribution, as confirmed in Estate of Fleming v. Commissioner.

State Law and the Uniform Act

State law controls who the property passes to after a refusal, even when federal tax law controls whether the refusal counts as a gift. The Uniform Disclaimer of Property Interests Act has been adopted in some form by more than 25 states, including Florida, North Carolina, and New Mexico.

Under UDPIA, a disclaimer is effective when delivered, and the property passes as if the disclaimant died immediately before the decedent. The consequence is that the disclaimed property follows the will’s contingent terms, the trust’s default takers, or the state intestacy statute, in that order.

A frequent misconception is that the disclaimant can choose who gets the property. You cannot. If the will leaves the rest to your sister as the contingent beneficiary, your sister takes the disclaimed share even if you wanted your own child to receive it. To redirect property to a different person, you would need a non-qualified disclaimer plus a separate gift, which defeats the tax purpose entirely.

How a Partial Disclaimer Works in Practice

A partial disclaimer can take three main forms under Treasury Regulation §25.2518-3: a disclaimer of a separate interest, a disclaimer of an undivided portion, or a disclaimer of a pecuniary amount. Each form has its own technical rules, and choosing the wrong form is one of the most common reasons partial disclaimers fail IRS review.

A separate interest disclaimer covers a specific asset, like one parcel of real estate out of three, or one bank account out of five. The asset must be capable of standing alone after the refusal.

An undivided portion disclaimer covers a fractional share that extends across the entire interest, such as 25% of every dollar and every asset in a residuary share. The fraction must apply to every substantial right in the property, not just the income or just the principal.

A pecuniary amount disclaimer covers a fixed dollar figure, such as “$100,000 of the cash bequest.” The regulation requires that the disclaimant not receive any benefit from the disclaimed amount, including interest earned on it before distribution.

Separate Interest Disclaimers

A separate interest is a property right that exists independently of other rights in the same gift. The IRS Private Letter Ruling 200127007 confirmed that a beneficiary may disclaim one of several specific bequests without affecting the others.

The plain meaning is that each numbered gift in a will is usually its own separate interest. If a will leaves you “my Honda Accord, my coin collection, and 100 shares of IBM,” you may disclaim any one of the three without touching the others.

Priya receives three separate bequests from her aunt’s will: a vacation home in Vermont, a $50,000 cash gift, and a brokerage account. Priya already owns a home she loves and does not want the Vermont property because of the property taxes and maintenance. Priya signs a written disclaimer of the Vermont home only, and the home passes to the contingent beneficiary named in the will, her cousin. Priya keeps the $50,000 and the brokerage account with no gift tax consequence.

A common misconception is that you can disclaim a separate interest and still receive its income for a few months. You cannot. Any acceptance of benefits, including a rental payment from the disclaimed property, voids the refusal under Treasury Regulation §25.2518-2(d).

Undivided Portion Disclaimers

An undivided portion is a vertical slice through the entire bequest. The regulation says the slice must apply to every right in the property and must extend over the entire term of the disclaimant’s interest.

For example, a disclaimer of “an undivided one-third of my residuary share” is valid because the one-third applies to every asset, every dollar, and every right within the residue. A disclaimer of “the income from one-third of my residuary share” is not valid, because it carves up the bundle of rights instead of taking a clean vertical slice.

David is the sole beneficiary of his father’s $3 million residuary estate. David wants his two children to benefit from one-third of the residue under the will’s contingent terms. David signs a disclaimer of “an undivided one-third interest in the residuary estate,” and the disclaimed third passes per stirpes to his children. David keeps the other two-thirds and avoids any gift tax on the transfer to his children, because the disclaimer is qualified under IRC §2518.

A misconception is that an undivided portion can be tied to a specific asset within a larger pool. It cannot. If David tried to disclaim “one-third of the residue, but only the stock portion,” the IRS would treat it as a non-qualified disclaimer because the fraction did not extend across all property in the residue.

Pecuniary Amount Disclaimers

A pecuniary disclaimer is a fixed dollar amount carved out of a larger bequest. The amount must be clearly stated and must not include any earnings the disclaimant accepted before signing.

Treasury Regulation §25.2518-3(c) gives a specific example: a beneficiary may disclaim $50,000 of a $100,000 cash bequest, and the disclaimed $50,000 passes to the contingent taker. The retained $50,000 is treated as accepted, and the disclaimant may receive interest only on the retained portion.

Eleanor inherits a $500,000 IRA from her sister. Eleanor wants to pass $200,000 of the IRA to her nephew, the contingent beneficiary on the account, because her nephew is in a lower tax bracket and can stretch distributions under the rules from the SECURE Act 2.0. Eleanor signs a pecuniary disclaimer of $200,000 within nine months, takes no distributions on that portion, and the custodian splits the IRA into two inherited IRAs. Eleanor keeps $300,000 and avoids gift tax on the $200,000 transfer.

A misconception is that interest earned on the disclaimed portion before signing can be ignored. It cannot. The disclaimant must also disclaim any income attributable to the disclaimed amount, or the entire refusal becomes non-qualified.

The Nine-Month Deadline and Why It Is Strict

The nine-month clock is the single most unforgiving part of disclaimer law. Under IRC §2518(b)(2), the written refusal must be received by the transferor, the legal representative, or the holder of legal title within nine months of the date of the transfer creating the interest, or within nine months of the disclaimant’s 21st birthday if later.

The plain meaning is that the date of death usually starts the clock. The consequence of missing the deadline by even one day is total loss of qualified status, which converts the refusal into a taxable gift.

A real example shows the harshness of the rule. In Estate of Fitzgerald v. Commissioner, a disclaimer delivered on day 274 instead of day 270 was held non-qualified, and the IRS assessed full gift tax on the transferred share. The Tax Court refused to grant equitable relief because the statute is jurisdictional.

A common misconception is that the IRS will grant an extension for hardship, illness, or late discovery of the inheritance. The IRS will not. The Tax Court ruling in Estate of Helen Bennett confirmed that even a beneficiary in a coma during the nine-month period cannot extend the deadline.

Exceptions and Tolling

The only meaningful exception is the minor’s exception. A disclaimant who is under 21 has nine months from the 21st birthday, regardless of when the transfer happened.

Another narrow rule applies to successive interests. If you receive a future interest in a trust, your nine-month clock starts on the date the original transfer was made, not the date your interest becomes possessory. Treasury Regulation §25.2518-2(c)(3) explains this rule and is a frequent trap for remainder beneficiaries.

Jamal is named as a remainder beneficiary in a trust his grandfather created in 1995. His grandfather dies in 2026, and Jamal’s interest becomes possessory. Jamal cannot disclaim, because the nine-month clock ran out in 1996, decades before he had any practical use for the gift.

Disclaiming Retirement Accounts

Disclaiming part of an IRA, 401(k), 403(b), or other retirement account is one of the most common uses of a partial disclaimer in modern estate planning. The IRS Publication 590-B confirms that a beneficiary may disclaim all or part of an inherited retirement account if the refusal meets §2518.

The strategy matters because of the SECURE Act’s 10-year rule for non-spouse beneficiaries. Pushing part of the account to a younger beneficiary, an eligible designated beneficiary, or a charitable remainder trust can produce large income tax savings.

The plain meaning is that the surviving spouse, who is usually the primary beneficiary, can refuse part of the account, and that portion drops to the contingent beneficiaries, often the children. The consequence is that the children take an inherited IRA subject to the 10-year rule, while the spouse keeps a spousal rollover on the retained portion.

Linda inherits her husband’s $1.8 million IRA. Linda has enough other assets and wants $600,000 of the IRA to go to their adult son, the contingent beneficiary. Linda signs a partial disclaimer of $600,000 within nine months of her husband’s death and does not take a required minimum distribution on the disclaimed portion. The custodian opens an inherited IRA for the son under SECURE Act rules. Linda rolls the remaining $1.2 million into her own IRA. There is no income tax on the transfer and no gift tax on the disclaimer.

A misconception is that taking a required minimum distribution from the inherited account before the disclaimer is harmless. It is not. Accepting any distribution from the share you plan to refuse is acceptance of a benefit and voids the refusal under Treasury Regulation §25.2518-2(d)(1).

Disclaimers and the Marital Deduction

Partial disclaimers are a powerful planning tool for married couples who want to fund a credit shelter trust or a bypass trust after the first spouse dies. The technique is called a disclaimer trust and is built into many modern wills.

The plain meaning is that the surviving spouse can decide, after the first death, how much of the estate to refuse and push into a bypass trust that uses the deceased spouse’s federal estate tax exemption. The retained portion qualifies for the unlimited marital deduction.

The consequence in 2026 is significant. The Tax Cuts and Jobs Act sunset has reduced the basic exclusion amount, and surviving spouses who disclaim into a properly drafted credit shelter trust can lock in the deceased spouse’s exemption against future appreciation.

Robert dies in 2026 with a $15 million estate, leaving everything to his wife Margaret. Margaret already has $8 million of her own assets. Margaret disclaims $7 million into a credit shelter trust under the will. The $7 million uses Robert’s exemption, grows outside Margaret’s estate, and avoids estate tax at her later death. The retained $8 million qualifies for the marital deduction and is taxed in her estate only if it exceeds her own exemption.

A misconception is that the surviving spouse can be a trustee with broad powers over the disclaimed trust. The spouse may serve as trustee but only with ascertainable standards under IRC §2041, or the disclaimed property will be pulled back into the spouse’s estate.

Mistakes to Avoid With Partial Disclaimers

A botched disclaimer is often worse than no disclaimer because it produces a phantom taxable gift on top of an inheritance the beneficiary never wanted. The IRS gift tax instructions for Form 709 treat a failed refusal as a present-interest gift on the day the deadline passes.

• Missing the nine-month deadline by even one day, which converts the refusal into a taxable gift under IRC §2518 and exposes the disclaimant to gift tax on the entire transferred share.
• Accepting any benefit from the disclaimed property, such as collecting one dividend, depositing a check, or living in the house, which voids qualified status under Treasury Regulation §25.2518-2(d).
• Trying to direct who gets the property, which is forbidden under §2518(b)(4) because a directed refusal is not unqualified and is treated as a gift from the disclaimant.
• Disclaiming the income only of an undivided portion, which violates the vertical-slice rule in Treasury Regulation §25.2518-3(b) and disqualifies the refusal.
• Taking a required minimum distribution before signing the disclaimer of an IRA share, which is acceptance of benefits and ruins the refusal under IRS Publication 590-B.
• Failing to deliver the written disclaimer to the personal representative, trustee, or account custodian, which makes the refusal ineffective under UDPIA §5 and state law.
• Disclaiming with a creditor in the wings, which the Supreme Court in Drye v. United States held cannot defeat a federal tax lien on the disclaimant.
• Disclaiming while on Medicaid, which is treated as an uncompensated transfer under 42 U.S.C. §1396p and triggers a Medicaid penalty period.
• Forgetting to address GST tax on disclaimers to grandchildren, which can produce a 40% generation-skipping transfer tax if exemption is not allocated.
• Using ambiguous language like “I disclaim part of the estate,” which fails the unqualified test and triggers a partial-but-uncertain transfer the IRS may challenge.

Real-World Named Examples

Sofia receives a $2 million bequest from her father’s will and a $500,000 life insurance policy as the named beneficiary. Sofia is a high earner in the 37% federal bracket and wants $1 million of the cash bequest to pass to her two children under the contingent provision. Sofia signs a pecuniary disclaimer of $1 million on day 60, keeps the life insurance, and her children each receive $500,000 outright with no gift tax due, because the disclaimer is qualified under IRC §2518.

Tomás is the sole heir of his uncle’s $4 million estate, which includes a small apartment building. Tomás does not want to manage real estate. He disclaims the building only, a separate interest disclaimer, and the building passes to his sister under the contingent clause. Tomás keeps the brokerage accounts and avoids both landlord duties and any gift tax exposure.

Aisha inherits a $1.5 million IRA from her mother and is the primary beneficiary. Her teenage children are listed as contingent beneficiaries. Aisha disclaims $600,000 of the IRA within nine months. The custodian opens two inherited IRAs for the children under the SECURE Act 10-year rule, Aisha keeps $900,000, and the family pays significantly less aggregate income tax over the next decade.

Court Rulings Every Disclaimant Should Know

The Supreme Court’s decision in Drye v. United States, 528 U.S. 49 (1999) settled that a federal tax lien attaches to property even after a state-law disclaimer. The plain meaning is that you cannot disclaim away an inheritance to dodge a federal tax debt, because federal law treats the inheritance as your property the moment it vests.

The Tax Court’s ruling in Estate of Monroe v. Commissioner, and the Fifth Circuit’s reversal, address whether disclaimers made under family pressure are still unqualified under §2518. The Fifth Circuit held that family negotiations do not by themselves make a refusal qualified, as long as the disclaimant receives no consideration.

The Tax Court’s opinion in Estate of Helen Christiansen v. Commissioner approved a partial disclaimer used in a formula clause that funded a charity with any excess value, even when the IRS challenged valuations later. The case is now the foundation of Christiansen disclaimers used in art and closely held business estates.

Do’s and Don’ts of Partial Disclaimers

• Do consult an estate attorney before signing, because the statute of limitations on gift tax and the irrevocability of the refusal leave no room for fixing errors after the fact.
• Do check the contingent beneficiaries first, because you cannot redirect property and the next taker is fixed by the document.
• Do put the refusal in writing with a clear identification of the property, dollar amount, or fraction being refused, as required by Treasury Regulation §25.2518-2(b).
• Do deliver the signed document to the personal representative, trustee, or account custodian and keep proof of delivery.
• Do disclaim retirement accounts before any RMD or distribution, to avoid the acceptance-of-benefits trap.
• Don’t accept any benefit from the property you plan to refuse, including rents, dividends, or interest.
• Don’t miss the nine-month deadline, because the IRS does not grant extensions for missed disclaimer deadlines.
• Don’t disclaim in a Medicaid planning window without checking the five-year look-back period, because disclaimers count as uncompensated transfers.
• Don’t try to disclaim assets that are subject to a federal tax lien, since Drye makes the refusal ineffective against the lien.
• Don’t use vague language like “some” or “part” without specifying the dollar amount, fraction, or asset.

Pros and Cons of Partial Disclaimers

• Pro: Lets a beneficiary save income tax by pushing retirement accounts to lower-bracket heirs under the SECURE Act 10-year rule.
• Pro: Funds bypass trusts and credit shelter trusts to lock in the deceased spouse’s federal estate tax exemption.
• Pro: Avoids unwanted property, like a hard-to-manage building or a family business, without gift tax.
• Pro: Protects the disclaimed share from the disclaimant’s future creditors in many states under UDPIA §5.
• Pro: Creates flexibility in post-mortem planning that allows the family to react to current tax law.
• Con: Irrevocable, so a change of heart after signing is not allowed.
• Con: Cannot direct who receives the disclaimed property, which can defeat the disclaimant’s wishes.
• Con: Does not defeat federal tax liens, per Drye v. United States.
• Con: Treated as a transfer for Medicaid purposes, which can cause a long ineligibility penalty.
• Con: Strict formality requirements make malpractice exposure significant for attorneys who get the writing wrong.

Step-by-Step Process for a Valid Partial Disclaimer

The process for a partial disclaimer follows the same steps as a full disclaimer but adds careful description of the refused share. The American College of Trust and Estate Counsel commentary on disclaimers outlines best practices.

Step 1 — Identify the contingent taker. Read the will, trust, or beneficiary designation to confirm exactly who receives the disclaimed share. If the document is silent, state intestacy law controls, and your refusal may produce an unexpected result.

Step 2 — Choose the form of partial disclaimer. Decide whether you are refusing a separate interest, an undivided portion, or a pecuniary amount. Each form has its own description requirements under Treasury Regulation §25.2518-3.

Step 3 — Draft the written refusal. The document should describe the decedent, the asset, the specific portion refused, and a statement that the refusal is irrevocable and unqualified. The Florida Bar disclaimer form template is one example used by many practitioners.

Step 4 — Sign and notarize. Most state statutes require a signature, and many require notarization or witnesses. The New York Estates, Powers and Trusts Law §2-1.11 sets one of the most detailed state-level standards.

Step 5 — Deliver within nine months. Deliver the signed refusal to the personal representative, trustee, or account custodian and keep certified mail receipts or written acknowledgment.

Step 6 — File with the probate court if required. Some states require filing with the probate court, and failure to file can void the refusal under state law even when federal tax law is satisfied.

Step 7 — Confirm tax reporting. Although a qualified disclaimer is not reported on Form 709, a non-qualified disclaimer is, and the disclaimant must file a gift tax return.

State Nuances Worth Knowing

State law variations matter because they determine the who and when of the property’s new path. The Florida statute on disclaimers, Chapter 739, is among the most thorough and tracks UDPIA closely.

California uses its own Probate Code §§260-295, which requires delivery within nine months and adds creditor-protection rules. The consequence in California is that a creditor of the disclaimant cannot reach the disclaimed share, except where federal law overrides under Drye.

New York’s EPTL §2-1.11 requires filing with the Surrogate’s Court within nine months and specifies acknowledgment before a notary. Texas’s Estates Code Chapter 122 allows partial disclaimers and includes specific rules for community property interests.

A common misconception is that federal §2518 alone controls. It does not. A refusal that meets federal law but fails state filing rules can produce a valid federal qualified disclaimer that nevertheless has no effect on who receives the property, leaving the disclaimant in legal limbo.
