Overview: What IRC 6035 and Form 8971 Require
The Surface Transportation and Veterans Health Care Choice Improvement Act of 2015 created IRC 6035 and, with it, a new Form 8971 reporting regime. The statute requires every executor who files (or is required to file) an estate tax return under IRC 6018 to report to the IRS and to each beneficiary the value of each asset included in the gross estate for estate tax purposes. The underlying policy goal is the basis consistency rule of IRC 1014(f): a beneficiary's initial basis in inherited property cannot exceed the value finally determined for estate tax purposes. Form 8971 is the mechanism that enforces that limit by putting the value on paper and in the hands of the IRS and each recipient before the beneficiary can dispose of the asset.
For estate practitioners, Form 706 filings and Form 8971 filings are now inseparable. An executor who completes Form 706 without simultaneously preparing Form 8971 and Schedule A for each required beneficiary faces IRC 6035 information-reporting penalties, potential personal liability under IRC 1014(f) for a beneficiary's subsequent inconsistent basis position, and the stacked exposure of an IRC 6662 accuracy penalty against the beneficiary if the beneficiary later overstates basis on a sale.
The September 2024 final regulations published as T.D. 9991 resolved several years of uncertainty about the scope of the reporting requirement. They narrowed the definition of "included property," clarified when the 30-day filing deadline runs, and confirmed the portability-only exception. The changes caught many practitioners off guard because the final regulations departed in significant ways from the proposed regulations that had been in circulation. This guide works through the T.D. 9991 framework, the penalty structure, and the documentation practices that support an IRC 6724 reasonable cause defense.
For background on how IRC 1014 governs the general basis rules for inherited property, see our companion guide on IRC 1014 and 1015 stepped-up and carryover basis rules.
Which Estates Must File: The IRC 6018 Threshold and the Portability-Only Exception
Form 8971 is required only when an executor is obligated to file Form 706. That obligation arises under IRC 6018 when the gross estate, plus adjusted taxable gifts, exceeds the applicable exclusion amount for the year of death. Estates that fall below the threshold have no Form 8971 obligation, regardless of how many assets pass to beneficiaries or how many of those assets receive a stepped-up basis under IRC 1014.
For the gross estate valuation rules that determine whether a Form 706 filing obligation exists, see our guide on IRC 2031 and 2032 gross estate valuation and Form 706.
Form 8971 is NOT required when an executor files Form 706 solely to elect portability of the DSUE amount under IRC 2010(c)(5)(A). The portability-only exception was confirmed in T.D. 9991. If the estate also has a taxable estate beyond what the unified credit offsets, the exception does not apply. Practitioners should confirm the current applicable exclusion threshold and DSUE election rules at IRS.gov, as these amounts adjust annually for inflation.
Once a Form 706 filing obligation exists, the executor must identify all property that qualifies as "included property" under T.D. 9991 and prepare a separate Schedule A for each beneficiary receiving such property. The portability election does not relieve the executor of this obligation when the estate has actual estate tax exposure.
For a full discussion of the portability election, the DSUE amount, and Form 706 filing strategy, see our guide on Form 706 estate tax return and portability.
T.D. 9991: The September 2024 Final Regulations
Treasury and the IRS issued T.D. 9991 in September 2024, finalizing regulations under IRC 6035 and 1014(f) that had been proposed years earlier. The final regulations retained the general framework of the proposed rules but made several substantive changes that narrowed the reporting obligation and modified the definition of property "acquired from the decedent."
The "Included Property" Definition
Under T.D. 9991, "included property" is defined as property whose inclusion in the gross estate increases the net estate tax liability of the estate. This is a net-effect test, not a gross-inclusion test. Property that is included in the gross estate under IRC 2031 through 2044 but that is fully offset by the marital deduction (IRC 2056), the charitable deduction (IRC 2055), or the unified credit (IRC 2010) does not satisfy the definition of included property and does not require Form 8971 reporting.
The practical significance is substantial. In large marital deduction estates where everything passes to a surviving spouse and generates no estate tax, no Form 8971 may be required even though Form 706 is filed for portability. Practitioners must work through the estate tax calculation asset by asset to determine which assets actually increase the tax liability before concluding that Form 8971 reporting is triggered for each one.
T.D. 9991 narrowed the definition of property "acquired from the decedent" compared to the proposed regulations. Under the final rules, fewer asset transfers qualify as "acquired from the decedent" for IRC 1014(f) purposes, which means fewer assets require Form 8971 Schedule A reporting. Practitioners who evaluated estates under the proposed regulations should re-examine those positions under T.D. 9991. Some assets previously believed to require reporting may fall outside the final rule entirely.
The 30-Day Post-Return Filing Deadline
IRC 6035(a)(3) requires Form 8971 to be filed with the IRS, and Schedule A to be furnished to each required beneficiary, no later than 30 days after the executor files the estate tax return (or is required to file it, if earlier). The T.D. 9991 regulations confirmed that extensions of time to file Form 706 do not extend the Form 8971 deadline beyond 30 days after the extended return is actually filed.
For supplemental Form 8971 filings triggered by a subsequent beneficiary transfer, the same 30-day period runs from the date of the transfer event, not from the original Form 706 filing date. This creates a rolling compliance obligation that persists long after the estate is otherwise closed.
Executor Personal Liability Under IRC 1014(f)
An executor is personally liable for the additional income tax a beneficiary owes due to an inconsistent basis position that the executor enabled through incorrect Schedule A reporting. This personal liability is not limited to estate assets and is not subject to indemnification from the estate or its beneficiaries. Executors who provide incorrect values on Form 8971 Schedule A do not shed this exposure when the estate closes. Every executor, estate attorney, and CPA advising an executor should understand this risk before signing any Schedule A value.
IRC 1014(f) works in conjunction with IRC 1014(a) and (b) to set the ceiling on a beneficiary's initial basis in inherited property. Under IRC 1014(a), a beneficiary's basis in property acquired from a decedent is generally the fair market value at the date of death. Under IRC 1014(f), that basis cannot exceed the value finally determined for estate tax purposes (or, if not finally determined, the value reported on the estate tax return and Form 8971).
When an executor overstates a value on Schedule A (whether deliberately or through error), the beneficiary who relies on that inflated value and claims a correspondingly high basis has taken an "inconsistent basis position." The tax consequences flow in two directions: the IRS can disallow the excess basis against the beneficiary, and the executor can be held personally responsible for the tax shortfall the inconsistency creates.
For the foundational analysis of how basis is determined for property received from a decedent, including the step-up rules and the treatment of IRD items that do not receive a step-up, see our guide on IRC 691 income in respect of a decedent.
The Stacked Penalty Risk: IRC 6035 Plus IRC 6662
An executor who fails to file Form 8971 on time faces IRC 6035 information-reporting penalties (calculated under IRC 6721 and 6722) on each unfiled or late return or statement. Separately, a beneficiary who overstates basis based on incorrect Schedule A values faces an IRC 6662(e) accuracy-related penalty of 20% of any underpayment attributable to the basis overstatement. If the overstatement qualifies as a "gross valuation misstatement" under IRC 6662(h) (the reported basis is 200% or more of the correct value), the enhanced penalty rate rises to 40% of the underpayment. These penalties do not offset each other; both can apply simultaneously to the same estate transaction.
The IRC 6035 penalty applies to the executor for the information-reporting failure. The IRC 6662 penalty applies to the beneficiary for the understatement of income tax. In theory, both apply simultaneously without any statutory offset between them. In practice, the most dangerous scenario is one where: (1) the executor files Form 8971 late or with incorrect values; (2) the beneficiary sells the inherited property at a gain and reports a basis that exceeds the estate-tax-determined value; and (3) the IRS audits the beneficiary's return and disallows the excess basis.
At that point, the IRS can assess IRC 6662 accuracy penalties against the beneficiary, the beneficiary can look to the executor under IRC 1014(f), and the executor may also owe IRC 6035 information-reporting penalties for the original failure to file or furnish. Layer in the IRC 6724 reasonable cause analysis at each level, and the combined exposure can be substantial in estates with high-value closely held business interests or real property that appreciates sharply after death.
Supplemental Form 8971 Reporting
A subsequent transfer of included property by a beneficiary to a third party triggers a separate supplemental Form 8971 filing obligation. The executor (or in some cases the beneficiary who made the transfer) must file the supplemental form with the IRS and furnish a revised Schedule A to the transferee within 30 days of the transfer. A failure to file a required supplemental Form 8971 triggers its own separate IRC 6035 penalty, calculated identically to the original filing penalty. T.D. 9991 clarified the mechanics and the 30-day clock for supplemental filings.
Supplemental reporting is one of the least understood aspects of the Form 8971 regime. Many executors assume their obligations end when the original Form 8971 is filed and the estate is closed. T.D. 9991 makes clear that this is incorrect. When a beneficiary who received included property subsequently transfers that property (by gift, by sale, or by bequest from the beneficiary's own estate), a new filing obligation is triggered so that the next holder of the property has the estate-tax-determined value on record.
The practical challenge is that executors are often unaware of beneficiary transfers that occur months or years after the estate closes. Practitioners who represent ongoing estates or who continue to advise beneficiaries after distribution should build a monitoring protocol into their engagement to flag triggering transfers before the 30-day window expires.

The IRC 6724 Reasonable Cause Defense
IRC 6724 waives the information-reporting penalties under IRC 6721 and 6722 (the provisions incorporated by IRC 6035) when the failure was due to reasonable cause and not willful neglect. Establishing reasonable cause for a Form 8971 penalty requires the executor to demonstrate: (1) that the failure was not the product of a deliberate decision to ignore the filing obligation; (2) that the executor exercised ordinary business care and prudence in attempting to comply; and (3) that circumstances beyond the executor's control caused the failure, or that the executor acted promptly to correct the failure when it was discovered.
Contemporaneous preparation of Schedule A values, the appraisals used on Form 706, and the supporting data underlying each valuation is the foundation of any IRC 6724 reasonable cause defense. The file should be assembled at the time Form 706 and Form 8971 are prepared, not reconstructed months or years later when the IRS inquires. That file should include: the qualified appraisal for each non-publicly-traded asset; date-of-death mean-price documentation for publicly traded securities; working papers and methodology notes for any minority or marketability discounts; professional engagement letters and appraiser credentials; and a reconciliation showing that every Schedule A value ties to the corresponding Form 706 line. Practitioners who build this file contemporaneously are in the strongest position to defend both the IRC 6035 penalty and any IRC 6662 assertion against the beneficiary.
The IRS has historically been willing to abate information-reporting penalties where the executor made a good-faith effort to comply, provided complete and accurate information to a qualified preparer, and corrected the failure promptly after it was identified. The weakest reasonable cause arguments are those where the executor was unaware of the Form 8971 filing obligation entirely, because the statute has been in effect since 2015 and practitioners are expected to know about it.
Stronger arguments arise where: (a) the T.D. 9991 final regulations changed the analysis after the executor had already taken positions based on the proposed rules; (b) the executor had a good-faith belief that the portability-only exception applied; or (c) an unusual asset classification question (for example, whether a particular asset qualified as "included property" under the net-effect test) was the subject of genuine legal uncertainty that a qualified practitioner analyzed and resolved in good faith.
Practical Compliance Checklist for Executors and Their Advisors
- Step 1: Determine whether a Form 706 filing obligation exists based on gross estate plus adjusted taxable gifts versus the applicable exclusion amount.
- Step 2: Determine whether the portability-only exception applies. If Form 706 is filed only for DSUE election and there is no estate tax, confirm that no included property passes to any beneficiary requiring Form 8971.
- Step 3: Identify all assets that qualify as "included property" under T.D. 9991 (property whose inclusion increases the net estate tax liability). This is an asset-by-asset, net-effect analysis, not a gross-estate list.
- Step 4: Obtain qualified appraisals for all non-publicly-traded assets before Form 706 is filed. Confirm that each appraisal uses the date-of-death standard under IRC 2031.
- Step 5: Prepare Schedule A for each beneficiary receiving included property. Every value on Schedule A must tie exactly to the corresponding line on Form 706.
- Step 6: File Form 8971 with the IRS and furnish Schedule A to each required beneficiary within 30 days of filing Form 706 (or the due date of Form 706, if earlier).
- Step 7: Build and retain the contemporaneous documentation file described in the IRC 6724 reasonable cause section above.
- Step 8: Advise each beneficiary of the IRC 1014(f) basis consistency rule and the limits it places on their basis in each item of included property.
- Step 9: Monitor for subsequent transfers of included property by beneficiaries, and file supplemental Form 8971 within 30 days of any such transfer.
- Step 10: If Form 706 values are later adjusted in an IRS examination or Tax Court proceeding, file a corrected or supplemental Form 8971 reflecting the finally determined values within 30 days of the adjustment becoming final.
Frequently Asked Questions
Who must file Form 8971 under IRC 6035?
An executor of an estate that is required to file an estate tax return (Form 706) because the gross estate exceeds the applicable exclusion amount must file Form 8971 and furnish Schedule A to each beneficiary who received property included in the gross estate. The filing obligation attaches to the executor personally. Estates that file Form 706 only to elect portability of the DSUE amount are not required to file Form 8971 under the portability-only exception confirmed in T.D. 9991.
When is Form 8971 due?
Form 8971 must be filed with the IRS, and Schedule A must be furnished to each beneficiary, no later than 30 days after the executor files Form 706 (or after the date Form 706 is required to be filed, if earlier). Extensions of time to file Form 706 do not extend the Form 8971 deadline beyond 30 days after the extended return is actually filed. Supplemental Form 8971 filings triggered by beneficiary transfers are due within 30 days of the transfer date.
What is "included property" under T.D. 9991?
Under T.D. 9991, "included property" is property whose inclusion in the gross estate increases the net estate tax liability of the estate. This is a net-effect test. Property that is included in the gross estate but is fully offset by the marital deduction, the charitable deduction, or the unified credit is generally not included property and does not require Form 8971 reporting. The T.D. 9991 definition is narrower than the gross-inclusion standard many practitioners assumed before the final regulations were issued.
What is the portability-only exception to Form 8971 filing?
An estate that files Form 706 solely to elect portability of the DSUE amount is not required to file Form 8971. This exception exists because a portability-only return does not establish an estate tax liability, and no estate tax value is being set for basis purposes under IRC 1014(f). If the estate both has taxable estate value and elects portability, the exception does not apply and the executor must file Form 8971 for all included property. Practitioners should confirm current IRS guidance at IRS.gov for threshold amounts.
How does executor personal liability work under IRC 1014(f)?
IRC 1014(f) limits a beneficiary's initial basis to the estate-tax-determined value of each included asset. If the executor provides an incorrect (overstated) value on Schedule A, and a beneficiary relies on that value to claim a basis higher than what the estate tax established, the executor is personally liable for the additional income tax the beneficiary owes because of the inconsistency. This personal liability is not capped, is not subject to indemnification from the estate, and persists after the estate closes. Every executor should treat accurate Schedule A preparation as a personal financial risk, not just a compliance formality.
What happens if a beneficiary takes an inconsistent basis position?
If a beneficiary reports a basis in inherited property that exceeds the estate-tax value reported on Schedule A, the IRS can disallow the excess basis on audit, recalculate the gain on any sale, and assess additional income tax plus interest. The beneficiary may also face an IRC 6662(e) accuracy-related penalty of 20% of the underpayment attributable to the basis overstatement, or the enhanced 40% gross valuation misstatement penalty under IRC 6662(h) if the claimed basis is 200% or more of the correct value. The executor who provided the incorrect Schedule A values may be held personally liable for the tax shortfall under IRC 1014(f).
What is the penalty for late or incorrect Form 8971 filing?
IRC 6035 incorporates the IRC 6721 and 6722 information-reporting penalty structure. For 2026, the per-failure penalty is $330 per return or statement not timely filed or furnished, subject to annual calendar-year caps that scale with the size of the filer. Failing to file with the IRS and failing to furnish to each beneficiary are each separate violations. Intentional disregard eliminates the calendar-year cap and raises the per-failure penalty to the greater of $3,300 or 10% of the aggregate amount of items required to be reported. Late filings receive graduated reduced penalties if corrected within 30 days or within the calendar year.
How does the IRC 6724 reasonable cause defense apply to Form 8971 penalties?
IRC 6724 waives IRC 6721 and 6722 penalties (incorporated by IRC 6035) when the failure was due to reasonable cause and not willful neglect. The executor must show ordinary business care and prudence in attempting to comply, and that circumstances beyond the executor's control caused the failure. The strongest reasonable cause argument rests on contemporaneous documentation: a complete file of appraisals, valuation workpapers, professional engagement letters, and Schedule A tie-outs assembled at the time Form 706 and Form 8971 were prepared. Good-faith reliance on a qualified preparer who received complete and accurate information supports reasonable cause; claiming ignorance of the statutory obligation generally does not.
What is a supplemental Form 8971, and when is it required?
A supplemental Form 8971 is required when a beneficiary who received included property subsequently transfers that property to another person. The executor (or in some cases the beneficiary who made the transfer) must file a supplemental Form 8971 with the IRS and furnish an updated Schedule A to the new recipient within 30 days of the transfer. This updates the basis information chain so the new holder knows the IRC 1014(f) ceiling. Failure to file a required supplemental Form 8971 triggers a separate IRC 6035 penalty. T.D. 9991 clarified the mechanics and 30-day timeline for supplemental filings.
How do the IRC 6035 and IRC 6662 penalties stack?
The IRC 6035 penalty is an information-reporting penalty assessed against the executor for failure to file or furnish Form 8971 and Schedule A. The IRC 6662 accuracy-related penalty is assessed against the beneficiary for understatement of income tax attributable to a basis overstatement. These penalties target different parties and different transactions, so both can apply simultaneously. The IRC 6662 enhanced penalty for gross valuation misstatements can reach 40% of the underpayment. An executor who fails to file Form 8971 (IRC 6035 exposure), whose incorrect Schedule A contributes to a beneficiary's basis overstatement (IRC 6662 exposure against the beneficiary), and who is then held personally liable under IRC 1014(f), faces three compounding layers of exposure on a single estate.
How does Form 8971 relate to Form 706 valuation positions?
Form 8971 and Schedule A must report the same values the executor reported on Form 706. Schedule A values cannot exceed Form 706 values for the same asset. If Form 706 values are later adjusted in an IRS examination or Tax Court proceeding, the executor must file a corrected or supplemental Form 8971 reflecting the finally determined values within 30 days of the adjustment. Inconsistencies between Form 706 values and Schedule A values are a red flag in IRS examination and can independently trigger penalties. Practitioners should prepare Form 8971 and Schedule A concurrently with Form 706 using the same appraisals and workpapers.
Can IRC 1014(f) apply to property passing outside of probate?
Yes. IRC 1014(f) and Form 8971 obligations are not limited to probate assets. Property that passes by operation of law (jointly titled assets), by beneficiary designation (IRA, life insurance), or through a trust can still qualify as included property if it is included in the gross estate on Form 706 and its inclusion increases the estate tax. The form of transfer (probate vs. nonprobate) does not determine whether basis consistency applies; the question is whether the asset was included property on Form 706. Executors must account for all such assets when preparing Schedule A, not just assets that flow through the probate process.
What assets are most commonly reported on Form 8971 Schedule A?
Schedule A most commonly lists real property (residential, commercial, and undeveloped land), closely held business interests (limited partnership units, LLC membership interests, and privately held stock), publicly traded securities (reported at the mean of the high and low trading prices on the date of death), and tangible personal property with significant value (artwork, jewelry, collectibles). Life insurance proceeds and IRD items such as traditional IRA balances are generally excluded from basis reporting because they do not receive a stepped-up basis under IRC 1014. Government bonds and cash equivalents are reported if they actually increase the estate tax under the T.D. 9991 net-effect test.
How does Form 8971 interact with IRC 691 income in respect of a decedent items?
IRD items (uncollected wages, accounts receivable of a cash-method business, deferred compensation, and traditional IRA balances) are included in the gross estate at fair market value but do not receive a stepped-up basis under IRC 1014. The beneficiary recognizes income when the payment is collected. Because the IRC 1014 basis step-up does not apply to IRD, the IRC 1014(f) basis consistency requirement generally does not apply to IRD items, and those assets ordinarily need not be reported on Form 8971 Schedule A solely because of their IRD character. Practitioners should nonetheless review each IRD item under T.D. 9991 to confirm whether it qualifies as included property requiring any reporting.
How should an executor document Schedule A values for an IRC 6724 defense?
The IRC 6724 reasonable cause file should be assembled contemporaneously (at the time Form 706 and Form 8971 are prepared, not after an IRS inquiry). It should include: a qualified appraisal for each non-publicly-traded asset; date-of-death mean-price documentation for publicly traded securities from brokerage records or exchange data; working papers and methodology notes for minority interest or marketability discounts applied in closely held entity valuations; copies of all appraiser engagement letters and professional credentials; and a reconciliation showing that every Schedule A value ties exactly to the corresponding Form 706 line. This file is the most effective tool for defeating both the IRC 6035 filing penalty and any IRC 6662 assertion against a beneficiary who sold included property at a gain.
What changed about the "acquired from the decedent" definition in T.D. 9991, and why does it matter?
T.D. 9991 narrowed the definition of property "acquired from the decedent" for IRC 1014(f) and Form 8971 purposes compared to the proposed regulations. The proposed regulations tracked the broad scope of IRC 1014(b), which encompasses property passing in many ways from a decedent. The final regulations tightened this definition so that fewer transfers qualify, reducing the universe of assets subject to the basis consistency requirement and the Form 8971 reporting obligation. For practitioners who advised clients on estates under the proposed regulation standards, those prior positions should be re-examined under T.D. 9991. Assets previously believed to require Schedule A reporting may fall outside the final rule, potentially eliminating a filing obligation that earlier analysis had flagged.
