How to Disclaim (Refuse) an Inheritance — and When It Makes Sense (2026)

What a Disclaimer Actually Does

A disclaimer is a formal, written refusal to accept an inheritance. Under federal law (IRC §2518), if your disclaimer meets four specific requirements, the IRS treats the property as though it was never transferred to you at all — the asset passes directly to the next beneficiary under the will, trust, or applicable state law.¹

The critical tax result: no gift tax, no income tax, no generation-skipping transfer tax. You are not making a gift to the next beneficiary. You never received the property, so you cannot be taxed on giving it away.

A disclaimer that does not meet all four federal requirements under §2518 is a "non-qualified disclaimer." A non-qualified disclaimer may still be effective under state law — the property passes to the next beneficiary — but the IRS treats the transaction as a gift from you to that beneficiary. The full value becomes a taxable gift.

The Four Federal Requirements Under IRC §2518

Section 2518(b) sets out exactly four conditions a disclaimer must satisfy to be "qualified" and thus free of gift tax. Missing any single one disqualifies the entire disclaimer.

1. Written and Delivered

The disclaimer must be in writing, signed by the disclaimant, and delivered to the transferor of the interest, the transferor's legal representative, or the holder of the legal title to the property (usually the executor or trustee).² An oral refusal — even one witnessed by family members — has no legal effect under federal law. It must be a document.

2. Timely — Within 9 Months

The written disclaimer must be received by the appropriate party no later than nine months after the date of the transferor's death.³ For inherited property, the clock starts the day the decedent dies — not when you find out about the inheritance, not when probate opens, not when the will is read.

Special rule for minors: If the beneficiary is under age 21 at the time of the transfer, the 9-month window does not start until the beneficiary turns 21. They then have 9 months from their 21st birthday to disclaim.

3. No Acceptance of Benefits

You cannot accept any interest or benefit from the property prior to making the disclaimer.⁴ Acceptance includes:

• Taking any distribution from an inherited IRA
• Cashing any check from an inherited account
• Using any property (living in an inherited house, driving an inherited car)
• Pledging the property as collateral
• Directing its investment (for IRAs, even changing the investment allocation may constitute acceptance)
• Selling any portion of inherited assets

Even a single $100 IRA distribution before the disclaimer letter is sent permanently destroys the ability to make a qualified disclaimer on the entire account. The rule is absolute — there are no de minimis exceptions.

4. No Direction to the Next Recipient

You cannot specify who receives the disclaimed property. It must pass "without any direction" by you — according to the terms of the will or trust, or to whoever would receive it if you had predeceased the transferor.⁵

In practice: you can know where the property will go (because you've read the will and the contingent beneficiary designation), and you can choose to disclaim based on that knowledge. You just cannot instruct anyone to give it to a particular person. The instrument controls the destination; you just choose whether to accept or refuse.

Reasons People Disclaim — and the Math Behind Each

Your Own Estate Is Already Large Enough

If your net worth is already near or above $15 million ($30 million for married couples),⁶ an additional inheritance just grows your estate tax exposure. The federal estate tax rate above the exemption is 40%. By disclaiming to a child or grandchild, you eliminate one generation of estate tax on that amount.

Example: You are worth $16M. You disclaim a $500,000 brokerage account to your 45-year-old daughter. Without the disclaimer, that $500K grows in your estate. With the disclaimer, your daughter receives it directly — at step-up basis — and avoids future 40% estate tax on its growth.

The IRA Would Push You Into a Higher Bracket

This is the most common reason to disclaim a traditional inherited IRA. Every dollar of a traditional inherited IRA distribution is ordinary income. If you are already in the 37% bracket, an additional $200,000/year of required distributions is taxed at 37% — or higher with state income tax.

If your adult child is in the 22% or 24% bracket, disclaiming the inherited IRA to them can save 13–15 percentage points of income tax on every required distribution over the 10-year window. On a $1,000,000 inherited IRA, that can represent $130,000–$150,000 in tax savings.

You Want to Skip a Generation

If you are financially comfortable and want the inheritance to benefit your children rather than yourself, a disclaimer is cleaner than a gift. It avoids gift tax complications, transfers at step-up basis (for non-IRA assets), and typically reduces the number of taxable estate transfers by one generation.

The Asset Has Negative Value or Risk

Not all inheritances are assets. Consider disclaiming:

• Real property with significant deferred maintenance or environmental contamination
• Closely held business interests with undisclosed liabilities
• A partnership interest with large recourse debt
• Property subject to ongoing litigation

Medicaid Planning — Use With Caution

Some beneficiaries consider disclaiming to avoid Medicaid estate recovery or to preserve eligibility. This is generally a mistake. Many states — and sometimes federal Medicaid rules — treat a disclaimer as a transfer for less than fair market value, triggering the 60-month Medicaid lookback penalty. Consult an elder law attorney before relying on a disclaimer for Medicaid planning. The rules vary significantly by state and are not covered by IRC §2518.

Disclaiming an Inherited IRA — The Most Common Scenario

Inherited IRAs are the most frequently disclaimed asset, and the rules are unforgiving. The custodian is the "holder of legal title" for IRA purposes, which means the written disclaimer must be delivered to the IRA custodian (e.g., Vanguard, Fidelity, Schwab) — not just to the estate executor — within 9 months of death.⁷

Where the IRA Goes After Disclaimer

The disclaimed IRA passes to whoever is named as the contingent beneficiary on the IRA beneficiary designation form — not to whoever inherits under the will. Wills do not govern IRAs. If there is no contingent beneficiary named, the IRA typically passes to the decedent's estate and through probate, losing the stretch/10-year option entirely.

Before disclaiming an IRA, confirm who the contingent beneficiary is. Request the beneficiary designation form from the custodian. If no contingent beneficiary is named, disclaiming will likely destroy significant value.

Timing the Disclaimer Against the 10-Year Rule

Under the SECURE Act and T.D. 10001 (July 2024), most non-spouse IRA beneficiaries face a 10-year depletion requirement with annual RMDs if the owner died after their Required Beginning Date. If your child is the contingent beneficiary and also subject to the 10-year rule, the main advantage of disclaiming is not eliminating the 10-year rule — it is moving the distributions to a beneficiary in a lower tax bracket.

If the contingent beneficiary is a charity, an eligible designated beneficiary (a minor child, disabled person, or someone within 10 years of the original owner's age), or a spouse, the disclaimer may provide substantially better options — stretching distributions over a life expectancy rather than 10 years.

Partial Disclaimers: Taking Some but Not All

A qualified disclaimer does not have to cover the entire inherited interest. You can disclaim a specific dollar amount or percentage of an inherited asset, keeping the rest for yourself.⁸

Example: You inherit a $2,000,000 IRA. You calculate that receiving $800,000 over 10 years keeps you in the 24% bracket. You disclaim the remaining $1,200,000 — 60% of the account — to your adult child in a lower bracket. The disclaimed portion, and all income attributable to it, passes to the contingent beneficiary.

For IRAs, partial disclaimers are typically expressed as a percentage (e.g., "I disclaim 60% of the inherited IRA account") rather than a dollar amount, because the account value fluctuates. The custodian will split the account accordingly and retitle the disclaimed portion for the contingent beneficiary.

State Disclaimer Laws

Every state has its own disclaimer statute — most follow the Uniform Disclaimer of Property Interests Act (UDPIA), but some states have additional requirements or shorter deadlines that can be more restrictive than federal law.

The key point: you must satisfy both federal law (IRC §2518) for the federal tax treatment and your state's law for the disclaimer to be legally effective in transferring the property. A disclaimer that complies with §2518 but not state law may not actually transfer title. Conversely, a disclaimer effective under state law but not §2518 will transfer the asset but create a taxable gift.

Some states require additional formalities — notarization, recording with the county, specific language in the disclaimer document, or filing with the probate court. An estate attorney in the decedent's state of domicile should draft the disclaimer document.

State-Specific Note: New York

New York has a 9-month disclaimer deadline that mirrors federal law, but requires the disclaimer to be filed in the Surrogate's Court in the county where the estate is pending and be accompanied by a court filing fee. If the disclaimed property includes real estate, additional recording requirements apply.

Medicaid Lookback in Key States

If you are receiving or soon expect to apply for Medicaid long-term care benefits, check with an elder law attorney in your state before disclaiming. Several states, including New York, Florida, and Texas, have agency guidance or case law treating disclaimers as disqualifying transfers subject to the 60-month lookback period.

What Happens to the Disclaimed Property

After a valid qualified disclaimer, the law treats you as having predeceased the transferor. The disclaimed property passes to whoever would have received it if you had died first — according to the governing document (will, trust, IRA beneficiary designation) or applicable state intestate succession law if no document applies.

You have no further rights, claims, or obligations with respect to the disclaimed property. You cannot "take it back" later. A qualified disclaimer is irrevocable.

The step-up in basis rules (IRC §1014) still apply: the contingent beneficiary receives the non-IRA assets at their date-of-death fair market value — the same basis they would have received if they had been the original named beneficiary. No tax disadvantage relative to them having been named directly.

4 Mistakes That Void the Disclaimer's Tax Benefits

1. Taking Any Distribution Before Deciding

One distribution. One check deposited. One dividend reinvested by the custodian — if you directed it. Any of these can constitute acceptance of a benefit, permanently voiding the right to make a qualified disclaimer on that asset. Call the custodian within days of the death and tell them you are evaluating a disclaimer. Most custodians will pause the account if you ask promptly.

2. Missing the 9-Month Deadline by Even One Day

There are no extensions, no hardship exceptions, and no IRS form to file for a late disclaimer. If you are overseas, hospitalized, or dealing with a protracted estate settlement, the clock does not pause. Build your timeline backward from day one: 9 months minus 2 weeks for drafting and delivery.

3. Disclaiming Without Knowing Who Gets the Property

The most damaging disclaimer scenario: you disclaim an inherited IRA, and then learn there is no contingent beneficiary named. The IRA reverts to the estate, loses the designated-beneficiary status, and must be distributed within 5 years if the owner died before their Required Beginning Date — or over the owner's actuarial life expectancy otherwise. The 10-year stretch option is gone.

4. Using a DIY Disclaimer Without an Attorney

The disclaimer document must precisely comply with both IRC §2518 and your state's disclaimer statute. A disclaimer that says "I hereby refuse the inheritance" without meeting all required elements — written delivery to the right party, proper identification of the disclaimed interest, correct timing — will not qualify. The stakes are too high for a do-it-yourself approach. Hire an estate attorney who practices in the decedent's state.

How to Proceed If You Are Considering a Disclaimer

The disclaimer decision is time-sensitive. Here is the practical sequence:

1. Do not touch the assets. Do not take any distributions, deposits, or benefits while you are evaluating.
2. Document the date of death. Your 9-month clock started the day the decedent died. Set a calendar reminder for the 7-month mark as your drafting deadline.
3. Request the governing documents. For IRAs: get the beneficiary designation from the custodian. For trusts: get the trust document. For probate assets: get the will. You need to know who receives what you disclaim before deciding.
4. Model the tax scenarios. Compare the total income tax under: (a) you keep everything, (b) you disclaim everything, (c) a partial disclaimer of a specific percentage. A fee-only tax advisor can run this analysis in 1–2 hours.
5. Hire an estate attorney in the decedent's state to draft the disclaimer document. Do not draft it yourself.
6. Deliver the disclaimer to the executor/trustee and (for IRAs) the custodian, before the 9-month deadline, with written proof of delivery.
