IRC 6901: Transferee Liability and Fiduciary Liability in Federal Tax Collection

1. The General Rule: Procedure, Not Substantive Liability

IRC 6901 is a federal collection statute, not a source of substantive liability. It authorizes the IRS to assess and collect from a transferee of property the same amount it could collect from the transferor, but only to the extent some independent body of law (state fraudulent transfer law, state successor liability doctrine, or IRC 3713(b) for fiduciaries) already makes the transferee liable for the transferor's obligation. Without an underlying substantive predicate, there is nothing for IRC 6901 to enforce.

The statute consolidates the IRS's collection tools into a single procedural track: assessment, notice, and Tax Court review. Before IRC 6901 was enacted, the IRS had to pursue transferees through equity suits in district court. Congress replaced that patchwork with a streamlined administrative process while preserving the fundamental principle that transferee liability depends on what applicable law outside the Code independently creates.

Under IRC 6901(a), the IRS may proceed against transferees "in the same manner and subject to the same provisions and limitations as in the case of the taxes with respect to which the liabilities were incurred." That phrase carries significant weight: it means the IRS must follow the notice and assessment procedures it would use against the original taxpayer, including issuing a notice functionally equivalent to a deficiency notice and affording the transferee Tax Court access before payment.

The statute reaches three categories of obligor: (1) transferees of property of taxpayers (IRC 6901(a)(1)(A)), (2) fiduciaries who distribute assets without satisfying federal tax claims (IRC 6901(a)(1)(B)), and (3) transferees of transferees (successive transferees). Each category carries its own limitations period under IRC 6901(c).

2. Who Is a "Transferee" Under IRC 6901(a)

IRC 6901(a)(1)(A) expressly identifies donees, heirs, legatees, devisees, and distributees as covered transferees. The list reflects Congress's original focus on estate-context distributions and donative transfers, but it does not define the outer boundary. Courts and the IRS have extended the category substantially beyond the statutory text, always through the lens of what state law imposes.

Donees and Gratuitous Transferees

A donee who receives property from a taxpayer without paying fair market value is the paradigmatic transferee. The IRS uses state fraudulent transfer law to establish that the transfer was constructively or actually fraudulent, then asserts IRC 6901 collection against the donee. The donee's personal exposure is capped at the value of the property received: the donee can owe no more than what the transferor conveyed.

Estate Distributees

Heirs, legatees, devisees, and beneficiaries who receive distributions from an estate are transferees if the estate had unpaid federal tax liabilities at the time of distribution. IRC 6901 allows the IRS to reach those distributees up to the value of assets they received. This category overlaps with fiduciary liability (the executor who made the distribution may also be personally liable), but they are distinct legal theories.

Corporate Shareholders and Liquidating Distributions

Shareholders who receive property in a corporate liquidation are transferees under IRC 6901 if the corporation had outstanding tax liabilities at the time of liquidation. In this context, each shareholder's exposure is limited to the value of property received in the liquidation distribution.

Asset Purchasers and Successor Liability

IRC 6901 does not create federal successor liability. An arm's-length asset purchaser who pays full consideration is not a transferee merely because the seller had outstanding tax obligations. The IRS must establish that state law (specifically, the UVTA or a state successor liability doctrine) independently makes the purchaser liable for the seller's tax debt. That requires either proof of fraudulent intent or inadequate consideration under the fraudulent transfer analysis, or satisfaction of the state-law tests for de facto merger or mere continuation.

3. Fiduciary Liability: IRC 6901(a)(1)(B) and IRC 3713(b)

Fiduciary liability under IRC 6901(a)(1)(B) has a different statutory architecture than transferee liability. The substantive predicate is IRC 3713(b), not state law. IRC 3713(a) establishes the priority of federal tax claims: the United States' claim for taxes is entitled to payment in full before a fiduciary makes distributions to creditors of the same or lower priority. IRC 3713(b) then provides that a personal representative, executor, administrator, trustee, or other fiduciary who distributes assets in violation of that priority is personally liable for the unpaid taxes to the extent of the distribution.

The connection to IRC 6901 is procedural: the IRS uses IRC 6901's assessment and notice machinery to assert and collect the fiduciary's personal liability under IRC 3713(b). The fiduciary receives a notice of transferee liability (just as an IRC 6901(a)(1)(A) transferee would), with the same Tax Court access rights.

Personal Representatives and Executors

An executor who distributes estate assets to beneficiaries without first paying the estate's outstanding federal income tax, gift tax, or estate tax obligations faces personal liability under IRC 3713(b) for the tax not paid, up to the value of assets distributed. The executor's exposure persists even if the executor was unaware of the outstanding liability, provided the liability existed and had priority at the time of distribution.

Trustees and Other Fiduciaries

Trustees of revocable and irrevocable trusts, corporate officers acting as fiduciaries, and court-appointed administrators are equally covered. In trust administration, the risk arises most sharply when the trust owns assets with deferred income (installment notes, IRAs, deferred compensation) that will generate taxable income after the grantor's death, and the trustee distributes principal before that income is recognized and the resulting tax paid.

Connection Between IRC 6901 and IRC 3713

The practitioner must distinguish the substantive rule (IRC 3713(b): personal liability for priority violation) from the enforcement procedure (IRC 6901(a)(1)(B): assessment and collection through the transferee-liability machinery). The fiduciary cannot defeat the IRC 6901 notice by arguing that the procedure is inapplicable; the proper defense is to contest whether a priority violation occurred at all (whether the tax had priority under IRC 3713(a) and whether assets were in fact distributed before it was paid).

4. Statute of Limitations Under IRC 6901(c)

IRC 6901(c) provides a separate limitations period for transferee assessment, running independently from the period applicable to the transferor under IRC 6501. The structure is additive: the IRS gets the full period to assess against the transferor, plus additional time to pursue the transferee.

Initial Transferee: One Additional Year

Under IRC 6901(c)(1), the IRS has one year after the expiration of the period of limitations on assessment against the transferor to assess the initial transferee's liability. If the transferor's three-year period under IRC 6501 expires on December 31 of Year 4, the IRS has until December 31 of Year 5 to assess the initial transferee, even if it never assessed the transferor within the three-year window.

Successive Transferees: One Additional Year Per Transfer

For each successive transferee (a transferee of a transferee), IRC 6901(c)(2) adds another year. A second-tier transferee's assessment period expires one year after the initial transferee's period, and so on. In multi-step asset movements, the total exposure window can extend well beyond the original limitations period.

The IRS is not required to have assessed the transferor's liability within the transferor's normal limitations period before asserting transferee liability. What matters is whether the transferor's underlying tax was valid and could have been timely assessed (that is, the transferor's period had not expired at the time the IRS moves against the transferee). The Tax Court has repeatedly confirmed that assessment against the transferor is not a jurisdictional prerequisite to a transferee-liability proceeding, but the IRS must still demonstrate that the underlying tax was valid and collectible.

Notice of Transferee Liability and IRC 6901(d)

IRC 6901(d) provides that the running of the transferee's limitations period under IRC 6901(c) is suspended during any period in which the IRS is unable to collect the tax from the transferee because of a bankruptcy stay or other legally imposed restriction on collection. This parallels the suspension rules applicable to transferors under IRC 6503. In bankruptcy practice, the suspension rule means the IRS may still pursue transferee liability after the bankruptcy discharge period, if the stay prevented timely assessment.

Coordination with the Transferor's Period

When a transferor has an open IRC 6501 period (for example, because of a false or fraudulent return or a substantial omission under IRC 6501(e)), the transferee's IRC 6901(c) period is calculated off that extended transferor period, not off the standard three-year window. Practitioners defending transferees must always identify the correct limitations period for the transferor as the starting point for the IRC 6901(c) calculation.

5. Assessment Procedure and Tax Court Jurisdiction

The IRS asserts transferee liability by issuing a notice of transferee liability, a document that functions identically to a notice of deficiency for purposes of Tax Court jurisdiction. The notice sets out the amount of the transferor's unpaid tax and the IRS's determination that the recipient is liable as a transferee or fiduciary under IRC 6901.

The Notice of Transferee Liability

The notice is typically a letter from the IRS Office of Chief Counsel or Collection function, accompanied by a Form 4340 (Certificate of Assessments, Payments, and Other Specified Matters) establishing the transferor's unpaid liability and a factual statement of the transfer. The notice triggers the 90-day window for Tax Court petition (150 days if addressed to a recipient outside the United States).

Tax Court Jurisdiction Under IRC 6901(f)

IRC 6901(f) expressly grants the Tax Court jurisdiction to redetermine transferee liability. The Tax Court's review is de novo on the transferee's liability, meaning the court examines both the correctness of the underlying tax (as assessed against the transferor) and whether the transferee is in fact liable under applicable law. A transferee who does not petition the Tax Court within the 90-day window loses prepayment review and must pay and then sue for a refund in district court or the Court of Federal Claims.

Burden of Proof

The burden of proof in a transferee-liability proceeding in Tax Court is split. The IRS bears the burden of establishing that the petitioner is a transferee and that a transfer occurred. Once the IRS establishes transferee status, the burden shifts to the transferee to prove that the transferor's underlying tax liability was incorrect, or that no fraudulent or voidable transfer occurred under state law. This allocation reflects the rationale that the transferee has access to the facts of the transfer, while the IRS has primary knowledge of the tax assessment.

Collection Due Process Rights

Once the IRS has assessed transferee liability (whether by default after the 90-day period expires or by Tax Court decision), the IRS may then proceed with collection actions (liens, levies, and garnishment) against the transferee's own assets. The transferee at that stage has the same collection due process rights under IRC 6330 as any assessed taxpayer: a right to a collection due process hearing before levy, with access to appeals and judicial review.

6. State Fraudulent Transfer Law as the Substantive Basis

For non-fiduciary transferees under IRC 6901(a)(1)(A), the IRS must establish liability under whatever state law applies to the transaction. In the vast majority of cases, that means analysis under the Uniform Fraudulent Transfer Act (UFTA) or its replacement, the Uniform Voidable Transactions Act (UVTA), which has been adopted in more than 40 states as of the mid-2020s, or the applicable state's common law of fraudulent conveyances for states that have not adopted the uniform act.

Actual Fraud vs. Constructive Fraud

Both the UFTA and the UVTA distinguish actual fraud (transfer made with actual intent to hinder, delay, or defraud a creditor) from constructive fraud (transfer made without reasonably equivalent value when the transferor was insolvent or became insolvent as a result of the transfer). Actual fraud is harder to prove but has a longer limitations period in most states and carries no value defense. Constructive fraud requires proof of insolvency and inadequate consideration.

The IRS typically proceeds under the constructive fraud theory because it does not require proof of the taxpayer's subjective intent: if the transferor was insolvent and the transfer was for less than reasonably equivalent value (including a gift), the transfer is avoidable and the transferee is liable. Proving insolvency at the time of transfer is often the central factual dispute.

UVTA Section 8: The Good Faith and Value Defense

UVTA section 8 (and its UFTA equivalent) creates a complete defense for a transferee who (1) took in good faith and (2) gave reasonably equivalent value. A bona fide arm's-length purchaser who paid full fair market value for the transferred property has a complete defense under UVTA section 8, regardless of the transferor's insolvency or intent. This is the primary defense in commercial asset-sale contexts.

State Law Determines Limitations Period for the Claim

The state fraudulent transfer limitations period (typically four years under UVTA section 9, or one year after the creditor could reasonably have discovered the transfer) governs whether the IRS's underlying state-law claim is timely, while IRC 6901(c) governs when the IRS can assess the federal transferee liability. Both must be satisfied. If the state-law claim is time-barred, the state-law basis for transferee liability fails, and IRC 6901 has nothing to enforce.

7. M&A Context: Successor Liability in Asset Acquisitions

Asset acquisitions, rather than stock acquisitions, are the primary context in which purchasers face IRC 6901 exposure from state successor liability doctrine. The general rule in asset purchases is that a purchaser does not assume the seller's liabilities; this is one of the principal reasons buyers prefer asset deals. That general rule, however, has four common-law exceptions that vary by state: (1) express or implied assumption of liabilities, (2) de facto merger, (3) mere continuation of the seller, and (4) fraudulent conveyance (the buyer took assets without adequate consideration to evade creditors, including the IRS).

De Facto Merger

A de facto merger is found when an asset acquisition is structured so that the acquiring entity is, in substance, a continuation of the target with no break in continuity of management, operations, or equity. Courts look to factors including: the same shareholders and management, the same business, payment in stock of the acquiring entity (rather than cash), and the seller dissolving after the transaction. When a de facto merger is found, state law imposes full successor liability on the buyer, and the IRS can use IRC 6901 to collect the seller's unpaid taxes from the buyer.

Mere Continuation

The mere continuation doctrine is narrower than de facto merger in most states: it requires that the buyer have substantially the same shareholders, directors, and officers as the seller. Some states have expanded this to a "continuity of enterprise" standard, focusing on continuation of business operations rather than equity identity. Practitioners structuring asset purchases must analyze the applicable state's version of the doctrine and avoid fact patterns (such as management rollover and seller dissolution) that trigger it.

Due Diligence and Pre-Closing Protections

Standard M&A due diligence in an asset acquisition should include tax lien searches (to identify federal tax liens under IRC 6321 that attach to assets), review of the seller's tax return filings and payment history, and requests for tax account transcripts for all federal tax periods that remain open under IRC 6501. Where the seller's tax history is unclear or the transaction is structured in a way that risks de facto merger or mere continuation findings, buyers routinely use:

• Tax indemnification provisions: the seller indemnifies the buyer for any IRC 6901 liability arising from the seller's pre-closing taxes, with a survival period that exceeds the IRC 6901(c) window.
• Escrow holdbacks: a portion of the purchase price is held in escrow for a period equal to the maximum IRC 6901(c) exposure window, to fund any transferee liability that the IRS asserts.
• Representations and warranties: the seller represents that all taxes have been filed, paid, or properly reserved, and that no open audits or pending assessments are known.
• Representations and warranties insurance (RWI): covers breaches of the seller's tax representations, including post-closing IRS assessments that trigger IRC 6901 claims against the buyer.

8. Estate Administration: Executor Exposure and IRC 6905 Discharge

Estate administration is the most common context for both transferee liability (distributions to beneficiaries) and fiduciary liability (the executor who makes those distributions). The two theories are complementary: the IRS may pursue the distributee under IRC 6901(a)(1)(A) and the executor under IRC 6901(a)(1)(B)/IRC 3713(b). Prudent estate administration requires managing both risks.

Priority of Federal Tax Claims Under IRC 3713(a)

IRC 3713(a) establishes that a claim of the United States for unpaid taxes has priority over any other claim against the insolvent debtor's estate, except for certain perfected secured interests. In estate administration, this means the executor must pay all outstanding federal tax liabilities (income taxes owed by the decedent, the estate's income taxes during administration, and estate tax) before distributing assets to beneficiaries, heirs, or other creditors of equal or lower priority. Paying a bequest before paying the IRS can trigger IRC 3713(b) personal liability.

Requesting Discharge Under IRC 6905

IRC 6905 provides executors and other fiduciaries a mechanism to limit personal exposure. To invoke it, the fiduciary must notify the IRS in writing (using Form 5495 or a similar written request) that the estate is being wound up and that the fiduciary intends to distribute the remaining assets. The IRS then has nine months from the date of that notice to assess any income tax or gift tax that the decedent owed. If the IRS does not issue an assessment within that nine-month window, the fiduciary is discharged from personal liability for those specific taxes.

Critical limitations of the IRC 6905 discharge:

• It applies only to federal income tax and gift tax liabilities of the decedent. It does not cover estate tax (the primary liability of the estate itself), employment taxes, or the estate's own income tax during the administration period.
• The discharge protects the fiduciary personally; it does not discharge the estate's underlying liability.
• The nine-month window begins when the IRS receives the fiduciary's written notice, not when it is mailed.
• The IRS can still assert liability for fraud or tax evasion by the decedent even after the discharge period.

Intersection of IRC 6901, IRC 3713, and State Probate Priority

State probate law also establishes a priority order for claims against the estate; that order often differs from the federal priority under IRC 3713(a). Because the Supremacy Clause controls, the federal priority overrides any conflicting state probate priority. An executor who follows state probate priority and pays state-law preferred creditors before the IRS may still be personally liable under IRC 3713(b) if the IRS's federal claim had priority. Practitioners advising executors must map both the federal priority (IRC 3713(a)) and the state probate priority and ensure federal tax claims are satisfied first.

9. Defenses Available to the Transferee

The defenses available in a transferee-liability proceeding under IRC 6901 fall into three categories: status defenses (the taxpayer is not a transferee), value and state-law defenses (the transfer was not voidable under applicable law), and tax-correctness defenses (the underlying transferor liability is wrong or time-barred).

No Transferee Status

The threshold defense is that the IRS has misidentified the taxpayer as a transferee. If the taxpayer did not receive property from the transferor, or if what was received was not a "transfer" within the meaning of applicable law (for example, a repayment of an arm's-length loan is not a transfer that state fraudulent transfer law would reach), the taxpayer is not a transferee and IRC 6901 does not apply.

Value Defense: Reasonably Equivalent Value

The value defense is the most commonly litigated defense in commercial contexts. Under the UVTA's constructive fraud theory, a transfer is avoidable only if the transferor received less than reasonably equivalent value. If the transferee paid fair market value for the transferred property, the transfer is not avoidable as a constructive fraud, and IRC 6901 fails. The value defense is available even when the transferor was insolvent at the time of transfer, as long as the consideration was adequate. Proving value typically requires expert testimony on the fair market value of the transferred property at the time of transfer.

Good Faith Purchaser Defense

UVTA section 8(a) provides a complete defense for a transferee who took in good faith and gave value (not necessarily full fair market value, but value). Good faith generally means the transferee had no knowledge of the transferor's fraudulent intent or, in states that frame it as notice, no actual or constructive notice that the transferor was acting to defraud creditors. The good faith purchaser defense is available even in an actual-fraud transfer if the good-faith requirements are met.

Statute of Limitations Defense

The transferee should assert both the state-law fraudulent transfer limitations period and the IRC 6901(c) federal limitations period as independent bars. Even if one is open, the other may be closed. The state-law period is often the tighter constraint on the IRS in transactions more than four years old.

Contesting the Underlying Tax

A transferee who petitions the Tax Court may contest the correctness and the amount of the transferor's underlying tax liability. This is a full de novo review on the tax merits. Relevant strategies include: identifying issues the transferor conceded without contest, marshaling evidence of deductions or basis adjustments the transferor failed to claim, and challenging the IRS's computation of penalties and interest on the underlying assessment.

No Priority Violation (Fiduciary Context)

In fiduciary-liability proceedings, the fiduciary can contest whether the federal tax claim actually had priority under IRC 3713(a) at the time of the distribution (for example, whether the tax had been assessed and was a valid claim, or whether the estate was solvent and had sufficient assets to pay all claims, making the priority rules moot).

10. Comparison: Transferee Liability, Fiduciary Liability, and IRC 6672

The table below maps the key attributes of transferee liability under IRC 6901(a)(1)(A), fiduciary liability under IRC 6901(a)(1)(B)/IRC 3713(b), and the Trust Fund Recovery Penalty under IRC 6672, which practitioners often encounter together in collection and insolvency contexts.
