The IRC 2056 marital deduction is the single most powerful estate tax deferral tool available to married couples, yet the OBBBA's permanent $15 million individual exemption has shifted the planning calculus in ways that make every existing marital deduction structure worth re-examining. This guide walks through the statutory framework, QTIP trust mechanics, QDOT requirements for non-citizen spouses, and the portability vs. QTIP decision as it stands under current law.
IRC 2056(a) allows an estate to deduct the full value of any property interest that passes from the decedent to a surviving U.S. citizen spouse. There is no ceiling. A decedent with a $50 million estate can transfer the entire taxable estate to a surviving citizen spouse and owe zero federal estate tax at the first death. The deduction is a deferral mechanism, not an exemption: the estate tax is simply postponed until the surviving spouse's own taxable estate is settled.
For most of the last two decades, the portability vs. QTIP decision was the central question in marital deduction planning. The answer turned on the size of the combined estate relative to the applicable exclusion amount, the state estate tax exposure, and the need to control the ultimate disposition of the trust remainder. The OBBBA changed the inputs. The individual applicable exclusion amount is now permanently set at $15 million (as adjusted for inflation; verify the current indexed amount at IRS.gov before advising clients), giving a married couple a combined sheltering capacity in the $30 million range through portability alone.
That shift has three practical consequences practitioners must confront:
For non-citizen surviving spouses, the marital deduction is categorically unavailable unless the property passes to a Qualified Domestic Trust (QDOT) under IRC 2056A. That analysis is independent of the exemption amount and has not changed structurally under the OBBBA, though the QDOT's practical importance increases when the decedent's estate exceeds the available exemption.
The marital deduction is authorized by IRC 2056(a): "For purposes of the tax imposed by section 2001, the value of the taxable estate shall, except as limited by subsection (b), be determined by deducting from the value of the gross estate an amount equal to the value of any interest in property which passes or has passed from the decedent to his surviving spouse." The deduction is limited only by what actually passes to the spouse and by the terminable interest rule.
The "passes to" requirement means the property must actually transfer to the surviving spouse, either outright, in trust, or by beneficiary designation. Property that passes to a third party, or that the surviving spouse disclaims under IRC 2518, does not qualify.
The marital deduction is denied for terminable interests: interests in property that will terminate or fail on the lapse of time, on the occurrence of an event or contingency, or on the failure of an event or contingency. The policy rationale is that a terminable interest transferred to the surviving spouse may never actually be taxed in the surviving spouse's estate if the interest expires before the spouse's death.
Examples of terminable interests that do not qualify without an exception:
IRC 2056(b) provides several exceptions that allow terminable interests to qualify for the marital deduction:
A QTIP trust earns its name from the statutory phrase "qualified terminable interest property." To qualify, three conditions must be met simultaneously:
The first condition requires that income be defined broadly enough to include reasonable amounts from trust assets; a trust that permits accumulation of income generally does not satisfy the all-income requirement. The second condition is what distinguishes the QTIP trust from the GPOA trust: the surviving spouse cannot redirect the trust remainder to new beneficiaries. This gives the decedent confidence that assets will ultimately pass to intended beneficiaries, typically children from a prior marriage or other family members.
The QTIP election is made by the executor on Schedule M of Form 706. The election is affirmative and elective: the trust does not automatically qualify for the marital deduction just because it meets the structural requirements. The executor must elect. Once made, the election is irrevocable. Treas. Reg. 20.2056(b)-7
Deadline Alert: QTIP Election
The QTIP election must be made on a timely-filed Form 706, including extensions granted under IRC 6081 (generally 6 months from the original due date). A missed QTIP election cannot be corrected after the estate tax return due date has passed. There is no statutory late-election procedure, and IRS relief via private letter ruling is discretionary, fact-specific, and not available to all taxpayers. Build QTIP election review into the Form 706 pre-filing checklist and calendar the return due date with adequate time for executor sign-off.
IRC 2056(b)(7)(B)(iv) expressly permits a partial QTIP election. The executor may elect QTIP treatment for a fractional share or a specific dollar amount of trust property. The partial election serves several functions:
Planning Note: Protective QTIP Elections
In estates where the marital deduction may be unnecessary because the estate appears to be under the applicable exclusion amount, the executor may nonetheless make a protective QTIP election on the timely-filed Form 706. The protective election preserves the option to qualify the property for the marital deduction if the estate is later determined to be taxable (for example, if assets are revalued upward on audit or the estate's deductions are disallowed). The IRS has issued guidance on when protective elections will be respected; the protective election must be made in a manner consistent with that guidance to be effective. Practitioners should evaluate whether a protective election is warranted on every Form 706 where the estate's taxability is uncertain.
The QTIP trust's deferred tax arrives at the surviving spouse's death. IRC 2044 requires inclusion of the full fair market value of all QTIP property in the surviving spouse's gross estate at date of death, as if the surviving spouse owned the property outright. The QTIP deferred at the first death becomes fully taxable at the second death.
Under IRC 2207A, the surviving spouse's estate is entitled to recover from the QTIP trustee the portion of the estate tax attributable to the QTIP inclusion, unless the decedent's governing instrument explicitly waives this right of recovery. Practitioners drafting QTIP trusts should address the IRC 2207A right of recovery expressly to avoid ambiguity.
Illustrative Example: QTIP at the Second Death
Decedent's estate: $20 million gross estate. Applicable exclusion amount: $15 million (verify the current indexed amount at IRS.gov). Executor elects portability and a partial QTIP election, sheltering $5 million in a QTIP trust and using the $15 million exclusion to absorb the remainder of the estate.
At the surviving spouse's death, the QTIP trust has appreciated to $8 million. The $8 million is included in the surviving spouse's estate under IRC 2044, in addition to the surviving spouse's own assets. The combined estate is taxed at the applicable rates. The step-up in basis under IRC 1014 applies to the QTIP assets included in the surviving spouse's estate, resetting the income tax basis of appreciated assets to fair market value at the second death.
The unlimited marital deduction under IRC 2056 is not available for transfers to a surviving spouse who is not a U.S. citizen at the time of the decedent's death. The policy rationale is straightforward: if a non-citizen surviving spouse receives the assets, leaves the United States, and dies abroad, the IRS may be unable to collect the deferred estate tax at the second death. The QDOT is the statutory solution Congress created in 1988 to permit the marital deduction for non-citizen spouses while preserving the government's collection mechanism.
A limited alternative for smaller transfers: IRC 2523(i) permits an annual exclusion of up to $18,000 (as of the most recent adjustment; verify the current amount at IRS.gov, as this figure adjusts annually) for gifts to a non-citizen spouse, in lieu of the unlimited gift tax marital deduction that applies to citizen spouses. This exclusion is a gift tax planning tool, not a substitute for the QDOT for large transfers or for estate tax purposes. Practitioner note: confirm the current indexed amount before advising.
For a transfer to a QDOT to qualify for the estate tax marital deduction, the trust must satisfy several requirements under IRC 2056A and Treas. Reg. 20.2056A-2:
Critical Compliance: QDOT Must Be Funded Before Filing
Failure to satisfy the QDOT structural requirements at the time of filing the estate tax return results in loss of the marital deduction for the property in question. The QDOT must be established and funded, or a binding agreement to fund it must be in place, before the estate tax return is filed. This is not a correctable error after filing. In estates involving a non-citizen surviving spouse, QDOT planning should begin immediately after the decedent's death, well before the Form 706 due date. See Treas. Reg. 20.2056A-3 for the funding rules and timing requirements.
The QDOT defers, rather than eliminates, the estate tax. An estate tax (computed at the first decedent's marginal estate tax rate) is imposed:
Income distributions from the QDOT are not subject to the QDOT estate tax; they are taxable income to the surviving spouse in the usual manner.
If the non-citizen surviving spouse becomes a U.S. citizen before the estate tax return is due (generally 9 months from the date of death, with a 6-month extension available), the unlimited marital deduction applies, and no QDOT is required. For non-citizen spouses who are candidates for naturalization, the timing of the citizenship application relative to the estate tax return due date is a critical planning consideration. The gift tax annual exclusion for non-citizen spouses also converts to the unlimited marital deduction if citizenship is obtained. Practitioners advising on estates with non-citizen spouses should evaluate naturalization timing before defaulting to a QDOT.
OBBBA Exemption Update
The One Big Beautiful Budget Act (OBBBA) made the $15 million individual applicable exclusion amount permanent and indexed for inflation. The combined federal exemption for a married couple using portability is approximately $30 million (as adjusted; verify the current indexed amount at IRS.gov before advising clients). This figure materially changes the portability vs. QTIP analysis for the majority of married couples. Update existing estate plans accordingly.
Portability, governed by IRC 2010(c) and elected on a timely-filed Form 706 for the first-to-die's estate, transfers the deceased spouse's unused exclusion (DSUE) to the surviving spouse. If a married couple's combined estate is comfortably below the combined exemption, and neither state estate tax exposure nor remainder control is a concern, the portability election alone may be sufficient planning. The surviving spouse uses the DSUE plus the surviving spouse's own applicable exclusion at the second death to shelter the entire estate from federal estate tax.
See the Form 706 and portability DSUE practitioner guide for the mechanics of the portability election, the Form 706 filing requirement, and the DSUE computation.
Even with a $15 million-plus individual exemption, the QTIP trust remains the right answer in several fact patterns:
For a full analysis of the OBBBA's impact on estate and gift tax planning, see the IRC 2010 and OBBBA permanent $15 million exemption guide.
State Tax Alert: Decoupling
Several states impose a separate estate tax with an exemption threshold significantly lower than the federal applicable exclusion amount. In these states, a married couple may face state estate tax at the first death even if no federal estate tax is due. QTIP elections made for state estate tax purposes may differ from the federal election. Verify current state law and the state's QTIP election procedures for each jurisdiction at issue before filing.
States including Massachusetts, Oregon, Washington, Illinois, and others impose estate tax at thresholds that can be as low as $1 million (verify the current threshold for each state; state law changes frequently). In these states, the QTIP election for state purposes can defer state estate tax at the first death by qualifying trust property for the state marital deduction, even when no federal QTIP election is necessary.
In decoupled states, the conventional two-trust plan remains relevant:
Under the OBBBA, the federal credit shelter amount has increased to $15 million (as adjusted; verify at IRS.gov), which means a greater portion of the estate may be funded into the credit shelter trust without incurring federal estate tax. The state credit shelter trust is separately sized to the applicable state exemption. Practitioners must model the combined federal and state estate tax burden at each spouse's death to optimize trust funding.
Some decoupled states require a separate QTIP election on the state estate tax return, independent of the federal Schedule M election. Failure to make the required state election can result in state estate tax at the first death even when the federal QTIP election is properly made. Review the state-specific return instructions for each jurisdiction involved before filing. Do not assume the federal election carries over to the state return.
Trusts that appear to satisfy the QTIP requirements often fail on a careful reading of the trust instrument. Common traps include income that can be accumulated rather than distributed annually, trustee discretion to withhold income, and income interests that terminate on the occurrence of a contingency (such as remarriage). Review the trust instrument against the all-income and no-power-of-appointment requirements before electing QTIP treatment.
Most well-drafted estate plans use formula clauses to allocate assets between the marital deduction share and the credit shelter share. The formula must be precise enough to fund the QTIP trust with the intended amount while preserving the credit shelter trust at the intended level. Ambiguous formula clauses generate administrative disputes and can result in an unintended estate tax at the first death if the marital share is underfunded.
For estates with a mix of asset types, non-pro-rata funding can create income tax complications: different assets funded into the marital trust vs. the credit shelter trust will have different income tax bases, affecting the income tax efficiency of the combined structure over time. The IRC 1014 step-up in basis applies to QTIP property included in the surviving spouse's estate under IRC 2044, resetting the income tax basis at the second death; the credit shelter trust does not receive a second step-up.
For an analysis of how retained interests can cause estate inclusion and complicate marital deduction funding, see the IRC 2036 and 2038 retained interest and estate inclusion guide.
In community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin), one-half of community property is already in the surviving spouse's estate by operation of law; only the decedent's one-half of community property is eligible for the marital deduction. Errors in identifying the community vs. separate property character of assets can result in an overstated marital deduction (claiming the deduction on the spouse's half) or an understated gross estate.
Property located abroad may have limited deductibility under IRC 2056 depending on applicable treaties and whether the property is included in the U.S. gross estate. The interaction of the marital deduction with foreign situs assets and applicable tax treaties requires country-specific analysis.
Property passing to the surviving spouse subject to a mortgage or other encumbrance reduces the net value of the marital bequest. The marital deduction is allowed only for the net equity (the fair market value of the property minus the debt), unless the estate pays off the encumbrance before distribution. Practitioners should review debt-encumbered property carefully to ensure the marital deduction reflects the correct net value.

Americas Tax: Marital Deduction Planning
Americas Tax advises clients and practitioners on marital deduction planning, QTIP election strategy, and the portability vs. QTIP decision under the OBBBA. Contact us to analyze the right structure for a specific estate, including QDOT planning for non-citizen spouses and state estate tax optimization.
| Planning Scenario | Outright Bequest | QTIP Trust (IRC 2056(b)(7)) | General Power of Appointment Trust | QDOT (IRC 2056A) | Practitioner Note |
|---|---|---|---|---|---|
| 1. Estate tax deferral at first death | Full deferral; assets pass outright to surviving spouse, no estate tax if spouse is a U.S. citizen. | Full deferral for the elected portion; QTIP election on Schedule M of Form 706 is required. | Full deferral; trust qualifies under IRC 2056(b)(5) if spouse holds a general power of appointment. | Full deferral for property transferred to a qualifying QDOT; mandatory for non-citizen spouses to access any marital deduction. | Deferral is identical across all four structures for a U.S. citizen spouse. For non-citizen spouses, the QDOT is the only path to any federal estate tax marital deduction. |
| 2. Surviving spouse control over principal | Unrestricted; surviving spouse owns the assets outright and can do anything with them. | None over remainder; surviving spouse receives income annually but cannot redirect principal to anyone other than the surviving spouse during lifetime. | Unrestricted; the general power of appointment gives the surviving spouse full control, including the power to appoint to the spouse's own estate. | Restricted; principal distributions are subject to QDOT estate tax (except hardship distributions). The surviving spouse may be entitled to income distributions tax-free. | The QTIP trust is the only structure that combines marital deduction eligibility with restriction on the surviving spouse's control over the ultimate disposition of the trust remainder. |
| 3. Applicable exclusion use (portability) | Portability election on Form 706 transfers the DSUE to the surviving spouse; outright bequest does not itself use the decedent's exclusion. | QTIP trust can be combined with a credit shelter trust to use the decedent's applicable exclusion at the first death; partial QTIP election calibrates the marital deduction. | Same as QTIP trust; a partial GPOA election with a credit shelter trust is structurally identical from an exemption-use standpoint. | The decedent's applicable exclusion reduces the taxable estate before the QDOT marital deduction applies; portability of DSUE is available to the non-citizen surviving spouse who becomes a citizen before the estate tax return is filed. | Under the OBBBA $15 million permanent individual exemption (verify the current indexed amount at IRS.gov), many estates can shelter the combined estate through portability alone, without a credit shelter trust or QTIP trust. |
| 4. Non-citizen spouse eligibility | No marital deduction for outright bequests to a non-citizen spouse (IRC 2056(d)). | A QTIP trust does not qualify for the marital deduction for a non-citizen spouse unless it also satisfies the QDOT requirements of IRC 2056A. | Same as QTIP: a GPOA trust for a non-citizen spouse requires QDOT compliance to access the marital deduction. | The QDOT under IRC 2056A is the exclusive mechanism for claiming the marital deduction when the surviving spouse is not a U.S. citizen at the decedent's death. | Non-citizen surviving spouses who naturalize before the estate tax return is filed are treated as citizen spouses for marital deduction purposes; evaluate naturalization timing before committing to a QDOT structure. |
| 5. Remainder beneficiary protection | None; the surviving spouse owns the assets and may leave them to anyone, including a new spouse or unintended beneficiaries. | Full protection; the remainder beneficiaries designated in the trust instrument are irrevocable. The surviving spouse cannot redirect the remainder. | None; the surviving spouse's general power of appointment allows redirection of the entire trust corpus to any person, including a new spouse. | Remainder beneficiaries are protected to the extent designated in the QDOT instrument, subject to applicable state law and the non-citizen surviving spouse's rights under the trust. | For blended families and estates with children from a prior marriage, the QTIP trust is the only marital deduction vehicle that provides meaningful remainder beneficiary protection. |
| 6. GST exemption allocation | GST exemption can be allocated to outright gifts by gift tax return; no structural efficiencies from a trust. | GST exemption can be allocated to QTIP trust assets, but QTIP trust property included in the surviving spouse's estate under IRC 2044 is treated as if it is the surviving spouse's own property for GST purposes, potentially complicating GST planning at the second death. | Same as QTIP for GST purposes; GPOA trust property is included in the surviving spouse's estate and the GST analysis applies at the second death. | GST exemption allocation to a QDOT follows the same general rules, subject to the added complexity of the QDOT estate tax at distributions and at the second death. | Portability does not transfer GST exemption. For estates with significant multi-generational transfer goals, the QTIP trust structure allows targeted GST exemption allocation at the first death. See the Form 709 guide for gift-side GST allocation considerations. |
| 7. State estate tax planning (QTIP election decoupling) | Outright bequests to a surviving spouse qualify for the state marital deduction in most decoupled states, deferring state estate tax to the second death. | QTIP election for state estate tax purposes may need to be made separately on the state estate tax return; verify the state's election procedures. Allows deferral of state estate tax on the QTIP share to the second death even when no federal election is necessary. | GPOA trust generally qualifies for the state marital deduction in decoupled states on the same basis as a QTIP trust; verify state law. | State treatment of QDOTs varies; not all states follow federal QDOT rules. Verify current state law for the state(s) with estate tax jurisdiction over the estate. | Verify current state law for each jurisdiction at issue. Several states impose estate tax at thresholds significantly below the federal applicable exclusion amount; the QTIP election for state purposes is often the key state tax planning lever at the first death. |
| 8. Step-up in basis at surviving spouse death (IRC 1014) | Full step-up in basis on all assets in the surviving spouse's estate at the date of death; assets received outright from the first decedent receive a second step-up if included in the surviving spouse's estate. | QTIP property is included in the surviving spouse's estate under IRC 2044 and receives a full step-up in basis under IRC 1014 at the second death. Appreciated QTIP assets benefit from basis reset. | Same as QTIP; GPOA trust property included in the surviving spouse's estate under IRC 2041 receives a full basis step-up at the second death. | QDOT corpus included in the surviving spouse's estate at death receives a step-up in basis under IRC 1014, same as other estate assets. The step-up applies only to the appreciated portion; the QDOT estate tax is a separate computation. | The credit shelter trust (bypass trust) does not receive a second step-up in basis at the surviving spouse's death because it is not included in the surviving spouse's estate. For highly appreciated assets, the QTIP or outright bequest structure may produce a superior combined income and estate tax outcome. Run the income tax basis analysis alongside the estate tax model. |
| 9. Income distribution flexibility | Not applicable; the surviving spouse owns the assets outright and receives all income and principal. | Mandatory all-income distribution to the surviving spouse at least annually. No discretion to accumulate income. The trustee may distribute principal under the trust instrument, but no power in any person to appoint principal to anyone other than the surviving spouse during the spouse's lifetime. | Same mandatory income distribution requirement as QTIP trust under IRC 2056(b)(5). The general power of appointment gives the spouse additional principal access. | Income distributions from the QDOT are not subject to the QDOT estate tax; only distributions of principal trigger the deferred estate tax (except hardship distributions). Income distributions can be made freely. | The mandatory all-income distribution requirement in QTIP and GPOA trusts can create income tax friction in high-income environments; a trust's income may be taxed at the compressed trust income tax rates if it is not distributed. Verify the trust's income tax profile in tandem with the estate tax analysis. |
| 10. QTIP election timing and protective QTIP elections | Not applicable; outright bequests do not involve a QTIP election. | QTIP election is made on Schedule M of a timely-filed Form 706 (including extensions). A protective QTIP election can be made even when the marital deduction appears unnecessary, preserving optionality if the estate is later found taxable. | GPOA trusts do not require a QTIP election; they qualify for the marital deduction automatically if the trust instrument grants the required general power of appointment. | The QDOT must be established and funded (or a binding agreement in place) before the estate tax return is filed; the QTIP election for a QDOT-QTIP combination is made at the same time and subject to the same deadline. | The QTIP election deadline is the most unforgiving deadline in estate tax planning. A missed election cannot be corrected after the return due date. For uncertain estates, a protective QTIP election is low-cost insurance. See the Form 706 guide for election procedures. |
What is the IRC 2056 marital deduction and how much can be deducted?
IRC 2056(a) authorizes an estate tax deduction for the full value of any property interest that passes from the decedent to a surviving U.S. citizen spouse. The deduction is unlimited; there is no dollar cap. A decedent with a $50 million gross estate can deduct the entire value if all property passes outright or in a qualifying form to a citizen spouse. The marital deduction defers the federal estate tax to the surviving spouse's death; it does not forgive it. Proper planning coordinates the unlimited marital deduction with the applicable exclusion amount (permanently set at $15 million by the OBBBA, as adjusted for inflation; verify the current indexed amount at IRS.gov), portability, QTIP trust mechanics, and, for non-citizen spouses, the QDOT rules under IRC 2056A.
What is a QTIP trust and how does the IRC 2056(b)(7) election work?
A Qualified Terminable Interest Property (QTIP) trust qualifies for the marital deduction under IRC 2056(b)(7) even though the surviving spouse's interest terminates at death. To qualify: (1) all income must be payable to the surviving spouse at least annually; (2) no person may have the power to appoint trust property to anyone other than the surviving spouse during the spouse's lifetime; and (3) the executor must make the QTIP election on Schedule M of a timely-filed Form 706. The election is irrevocable. The elected property qualifies for the marital deduction in the decedent's estate; the full fair market value of the QTIP property is included in the surviving spouse's gross estate under IRC 2044 at the second death. The QTIP trust allows the decedent to provide income to the surviving spouse while controlling the ultimate disposition of the trust remainder to named beneficiaries.
What is the difference between a QTIP trust and a general power of appointment marital trust?
Both qualify for the estate tax marital deduction, but the surviving spouse's control differs fundamentally. In a general power of appointment (GPOA) trust under IRC 2056(b)(5), the surviving spouse holds an unrestricted general power of appointment over the trust corpus, and can direct the assets to anyone, including the spouse's own estate or new family members. The trust is effectively treated as outright ownership. In a QTIP trust under IRC 2056(b)(7), the surviving spouse receives income but has no power to redirect the remainder: the decedent's estate plan controls who receives the trust assets at the surviving spouse's death. The QTIP structure is the vehicle of choice when the decedent wants to provide for the surviving spouse while preserving the remainder for children from a prior marriage or other intended beneficiaries.
How does the OBBBA $15 million exemption affect the portability vs. QTIP decision?
The OBBBA permanently raised the individual applicable exclusion amount to $15 million (as adjusted for inflation; verify the current indexed amount at IRS.gov). The combined exemption for a married couple using portability is approximately $30 million, which means many estates previously requiring a credit shelter trust plus QTIP structure now fall entirely below the federal exemption threshold. For these estates, portability via the DSUE election on a timely-filed Form 706 may be fully sufficient for federal purposes. However, QTIP trusts remain valuable for remainder beneficiary control in blended families, state estate tax planning in decoupled states, and GST exemption allocation. Practitioners must re-run the portability vs. QTIP analysis for all existing estate plans under the OBBBA and for every new engagement.
What is a QDOT and when is one required for a non-citizen spouse?
A Qualified Domestic Trust (QDOT) under IRC 2056A is required when the decedent's estate wants to claim the marital deduction for property passing to a surviving spouse who is not a U.S. citizen at the decedent's death. The unlimited marital deduction under IRC 2056 is unavailable for non-citizen spouses; the QDOT is the statutory workaround. The QDOT must have at least one U.S. citizen or domestic corporate trustee, the U.S. trustee must have the right to withhold QDOT estate tax on principal distributions, and the QDOT must be established and funded before the estate tax return is filed. An estate tax is imposed on principal distributions from the QDOT and on the entire QDOT corpus at the surviving spouse's death. Non-citizen surviving spouses who naturalize before the estate tax return due date are treated as citizen spouses; evaluate naturalization timing before committing to a QDOT.
Can a partial QTIP election be made on Form 706?
Yes. IRC 2056(b)(7)(B)(iv) expressly permits a partial QTIP election. The executor may elect QTIP treatment for a fraction or a specific dollar amount of trust property, leaving the non-elected portion subject to estate tax in the first estate (absorbed by the applicable exclusion amount) or directed to a credit shelter trust. The partial election is the principal tool for calibrating the marital deduction: it allows the estate to use the decedent's applicable exclusion amount at the first death (rather than porting it) while still qualifying the balance of the trust property for the marital deduction. Partial elections are also used to fund credit shelter trusts with optimal amounts for state estate tax planning and GST exemption allocation.
Is QTIP property included in the surviving spouse's estate?
Yes. Under IRC 2044, the full fair market value of all QTIP property (property for which a QTIP election was made at the first death) is included in the surviving spouse's gross estate at the date of the surviving spouse's death. The surviving spouse's estate is taxed on this inclusion as if the QTIP assets were the surviving spouse's own property. The QTIP trust receives a full step-up in income tax basis under IRC 1014 at the second death because the assets are included in the surviving spouse's estate. Under IRC 2207A, the surviving spouse's estate has the right to recover from the QTIP trustee the estate tax attributable to the QTIP inclusion, unless the governing instrument waives this right. Modeling the combined estate tax across both deaths is essential before recommending a QTIP structure.
What happens if the QTIP election is missed on the estate tax return?
A missed QTIP election is generally fatal. The election must be made on a timely-filed Form 706, including extensions. There is no statutory procedure for a late QTIP election after the return due date has passed. The IRS has granted relief via private letter ruling in limited circumstances, but PLRs are not precedential and relief is not guaranteed. If the election is missed, the trust property does not qualify for the marital deduction, and estate tax is due on the value of the trust at the first death, subject to the applicable exclusion amount and other available deductions. Practitioners should build QTIP election review into their Form 706 preparation workflow, calendar the return due date (including extensions) prominently, and conduct a pre-filing checklist review with the executor before the Form 706 is signed and filed.
The portability vs. QTIP decision depends on estate size, state of domicile, family structure, and GST goals. Americas Tax helps practitioners and their clients work through the full analysis under the OBBBA.
