Qualified Disclaimer: How to Refuse a Trust Inheritance (IRC § 2518)

When someone dies and leaves assets through a trust, a beneficiary does not have to accept what the trust document gives them. A qualified disclaimer under IRC § 2518 allows a beneficiary to irrevocably refuse an inheritance — and when done correctly, the refused assets pass as if the disclaimant had predeceased the settlor, with no gift tax triggered by the refusal itself. The catch: you have exactly 9 months from the date of transfer, and every requirement must be met. Missing any one of them invalidates the disclaimer.

What is a qualified disclaimer?

A qualified disclaimer is an irrevocable, unqualified refusal to accept an interest in property, made in compliance with the four requirements of IRC § 2518(b).¹ When a disclaimer is "qualified," the IRS treats the disclaimed interest as if it had never been transferred to the disclaimant — it passes directly to the next person in line without being subject to gift tax. If the disclaimer fails even one requirement, it is not qualified: the beneficiary is treated as having accepted the property and then transferred it, which is a taxable gift.

State law also governs how disclaimers work locally — most states have enacted the Uniform Disclaimer of Property Interests Act (UDPIA) or similar statutes — but federal gift-tax treatment requires meeting IRC § 2518, regardless of whether the disclaimer is valid under state law.

The four requirements under IRC § 2518(b)

1. The disclaimer must be in writing

An oral disclaimer has no legal effect for gift-tax purposes. The written disclaimer must be an irrevocable and unqualified refusal to accept the interest. It should identify the specific property or interest being disclaimed, state that the refusal is irrevocable, and be signed by the disclaimant. Attorneys typically prepare this document; there is no IRS form.

2. The written disclaimer must be received within 9 months

The written disclaimer must be received by the transferor of the property (or the legal representative), the holder of legal title, or the trustee of a trust — within 9 months of the date the interest was created.²

When does the 9 months start? For trust interests that vest at the settlor's death — the most common scenario — the 9 months runs from the date of death. For a living revocable trust that becomes irrevocable at the settlor's death, the clock starts when the trustee's obligation to distribute is created, which is also at death.

3. The disclaimant must not have accepted the interest or any of its benefits

Any acceptance — even partial — before the disclaimer is made destroys its validity. Acceptance includes:

• Using trust property (living in a trust-owned house, driving a trust-owned vehicle)
• Receiving income or interest payments from the trust
• Pledging trust assets as collateral
• Directing the trustee to reinvest, sell, or otherwise act on the assets for the disclaimant's benefit
• Exercising any ownership rights over the property before making the disclaimer

Receiving a required minimum distribution from an inherited IRA does not constitute acceptance under IRS guidance — this is an important exception for IRA disclaimers (see below). But receiving a discretionary trust distribution typically does count as acceptance of that distributed amount.

4. The disclaimed interest must pass without direction by the disclaimant

A disclaimant cannot dictate who gets the property after they refuse it. The disclaimed interest must pass either to the decedent's surviving spouse or to the person who would have received it if the disclaimant had died before the transfer.¹

In practice: if a trust distributes to "my children equally," and one child disclaims, that child's share passes as if they had predeceased the settlor — typically to their own children (per stirpes) under the trust document or applicable state law. The disclaimant cannot say "I don't want my share — give it to my sibling instead" unless the trust document would direct it there independently.

Why beneficiaries disclaim trust interests

Estate tax planning

With the OBBBA-permanent $15 million federal estate exemption per person ($30 million for married couples), most families do not face federal estate tax.³ But disclaimers can still be valuable in states with lower exemptions (Massachusetts and Oregon tax estates above $1 million; many other states have $2–6 million thresholds). A child who receives a trust inheritance in a high-exemption state but already has a taxable estate may disclaim to skip a generation — sending assets to grandchildren — and avoid future estate tax on those assets when the child eventually dies.

Generation-skipping to grandchildren

If the trust document says "to my children, or if any child predeceases me, to that child's descendants per stirpes," then a child who disclaims causes their share to flow to their own children (the grandchildren) as if the child had predeceased the settlor. If the settlor's remaining GST exemption is available to cover this transfer, the assets skip the child's estate entirely — potentially saving estate tax at both the child's and grandchild's deaths.

Creditor and divorce protection

A beneficiary with significant personal debt or facing a divorce may disclaim an inheritance they expect to receive. Because the disclaimed assets pass as if the disclaimant predeceased the settlor, the disclaimant's creditors generally cannot reach those assets. However, state fraudulent-transfer laws can void disclaimers made with intent to delay or defraud creditors — and the IRS treats a tax-motivated disclaimer that eliminates estate tax as not subject to state fraudulent-transfer law. Consult an attorney before using a disclaimer for creditor protection.

Simplifying estate administration

A beneficiary who doesn't need the money and prefers to keep assets flowing to grandchildren or charity may disclaim for non-tax simplicity reasons — fewer bank accounts to manage, fewer K-1s, or a preference to see grandchildren benefit directly.

Unmarried surviving spouse scenario

When one spouse dies and leaves a trust that does not qualify for the estate-tax marital deduction (e.g., a trust that gives the surviving spouse only a life income interest without a power of appointment), the surviving spouse might disclaim their trust interest so the assets pass to children directly, eliminating estate tax through the marital deduction and the children's own exemptions — though the $15M OBBBA exemption makes this less common now.

Partial disclaimers: disclaiming less than the whole interest

Under IRC § 2518(c) and the related regulations, a beneficiary may disclaim a severable portion of an interest rather than the entire interest.⁴ Valid partial disclaimers include:

• Undivided fractional interest: "I disclaim one-half of my share of the residuary trust"
• Specific assets: a beneficiary who receives a mix of a house and investment accounts can disclaim the house while accepting the investments (provided the interests are truly severable under the trust document)
• Separate interests: a beneficiary can disclaim the income interest in a trust while accepting the remainder interest (or vice versa), if the trust creates these as legally distinct interests

A beneficiary cannot disclaim a specific asset while directing the trustee to reinvest the proceeds for their benefit — that is direction, which violates requirement 4 above.

IRA disclaimers

A named beneficiary of an inherited IRA can make a qualified disclaimer within 9 months of the account owner's death, allowing the IRA to pass to the contingent beneficiary named on the beneficiary designation form.⁵ Key points:

• The 9-month period runs from the IRA owner's death, not from when the beneficiary was notified or when they opened an inherited IRA account
• Receiving the required minimum distribution for the year of death does not constitute acceptance — the disclaimant may receive the year-of-death RMD without forfeiting the right to disclaim
• To disclaim, the beneficiary must not open an inherited IRA account in their own name and draw distributions from it — that is acceptance
• The disclaimed IRA passes to whoever is named as contingent beneficiary; if there is no contingent beneficiary, the IRA passes under the IRA custodian's default rules (often the estate)
• The 10-year rule under SECURE 2.0 continues to apply to the contingent beneficiary who receives the disclaimed IRA — the disclaimer does not restart a new timeline

IRAs passing through a trust as the named beneficiary involve additional complexity (see-through trust rules, conduit vs. accumulation, compressed trust brackets). If an IRA is held in a trust and a trust beneficiary wants to disclaim their trust interest, consult the estate attorney — the analysis depends on how the trust is structured and whether the see-through rules apply. See our IRAs and Trusts guide for the underlying framework.

State law overlay

Most states have enacted the Uniform Disclaimer of Property Interests Act (UDPIA) or similar legislation, which generally parallels IRC § 2518. However, state disclaimer statutes matter for:

• Probate assets: assets passing through a will (not a trust) require compliance with state disclaimer rules in addition to federal requirements
• Real estate: a disclaimer of trust-held real estate must be recorded in the county where the property is located in some states
• Surviving spouse: some states protect a surviving spouse's creditor claims against a deceased spouse's estate — disclaimers designed to defeat these rights may not be enforceable under state law
• Medicaid: a Medicaid-eligible beneficiary who disclaims an inheritance may be treated as having made a disqualifying transfer, triggering a penalty period. Consult an elder-law attorney before disclaiming when any beneficiary receives government benefits

The trustee's role when a beneficiary disclaims

As trustee, receiving a disclaimer changes your distribution obligations. Before changing any distribution plan:

Step 1: Verify the disclaimer is legally valid

Your default should be to forward the disclaimer to the trust's estate attorney for review. A disclaimer that doesn't meet all four § 2518 requirements is not a qualified disclaimer — if you distribute as if it were and it later fails, you may be personally liable to the party who should have received the disclaimed property.

At minimum, confirm: (1) the disclaimer is in writing and signed; (2) you received it within 9 months of the settlor's death; (3) you have no evidence the disclaimant accepted the interest or benefits; and (4) the disclaimer does not purport to direct where the assets go.

Step 2: Determine who receives the disclaimed share

Read the trust document's anti-lapse or "if a beneficiary predeceases" provision. Most modern trusts distribute the disclaimed share as if the disclaimant predeceased — often per stirpes to the disclaimant's own descendants. If the trust is silent, state anti-lapse law applies. Do not assume you know the answer; read the document and confirm with the attorney.

Step 3: Document the disclaimer in trust records

Retain the original written disclaimer (or a certified copy) with the trust's permanent records. Note the date received, the specific interest disclaimed, and your determination of who receives the redirected share. This documentation is part of your fiduciary record and may be reviewed in any future beneficiary dispute or accounting challenge.

Step 4: Update the beneficiary accounting

If the trust is ongoing — not yet distributing final assets — update the trust's annual beneficiary accounting to reflect the disclaimer. The beneficiary who disclaimed should no longer appear as a qualified beneficiary receiving that interest, and the replacement beneficiaries must be added to your UTC § 813 reporting and notification duties.⁶

Step 5: Adjust Form 1041 and K-1 reporting

If income was already distributed to a disclaimant who later made a retroactive disclaimer (valid in some circumstances), work with the trust's CPA to determine whether prior K-1s need to be amended. For prospective distributions, K-1s are issued to the actual recipients of income — not to the disclaimant.
