    Section 1 · IRC §6321 — the statutory lien

    The "secret lien" that exists by operation of law.

    IRC §6321 provides: "If any person liable to pay any tax neglects or refuses to pay the same after demand, the amount (including any interest, additional amount, addition to tax, or assessable penalty, together with any costs that may accrue in addition thereto) shall be a lien in favor of the United States upon all property and rights to property, whether real or personal, belonging to such person." The §6321 lien arises automatically by operation of law upon the conjunction of three events: (1) assessment under IRC §6201; (2) notice and demand under IRC §6303 (operationalized by CP14); and (3) failure to pay. No additional IRS action is required — no NFTL filing, no court order, no notice beyond CP14.

    IRC §6322 confirms the timing: "Unless another date is specifically fixed by law, the lien imposed by section 6321 shall arise at the time the assessment is made and shall continue until the liability for the amount so assessed... is satisfied or becomes unenforceable by reason of lapse of time." The lien is sometimes called the "secret lien" because it exists by operation of law before any public notice — a taxpayer who owns real estate, bank accounts, and other property has a federal tax lien attached to all of it from the date of assessment, even though no NFTL appears in public records.

    The scope of the §6321 lien is broad, attaching to all property and rights to property: real estate; bank accounts; vehicles; business assets; accounts receivable; stocks, bonds, and financial instruments; intellectual property; pension and retirement accounts (subject to ERISA limitations on enforcement); insurance policies (cash value); trust interests; community property in community-property states. Critically, the lien attaches not only to property owned at the time of assessment but also to after-acquired property — everything the taxpayer acquires after the lien arises is also subject to it.

    Section 2 · Drye v. United States — the attachment framework

    What "property and rights to property" actually means.

    The Supreme Court's foundational interpretation of what "property and rights to property" means under §6321 came in Drye v. United States, 528 U.S. 49 (1999). The case involved Rohn Drye Jr., who disclaimed his inheritance under Arkansas state law to prevent IRS collection — Arkansas law treated a valid disclaimer as if the disclaimant had predeceased the decedent. Drye argued that under state law he had no property interest to which the federal tax lien could attach.

    The Supreme Court rejected this argument in a unanimous opinion by Justice Ginsburg. The Court held that "state law controls in determining the nature of the legal interest which the taxpayer had in the property" but "the consequences that attach to those interests are matters left to federal law." Applying this framework, the Court held that Drye's right to receive his inheritance was a "right to property" within §6321, and his attempt to disclaim it was an exercise of that right — which itself was subject to the federal tax lien under federal law. State-law disclaimer could not defeat the federal lien.

    The Drye framework — subsequent cases:
    • United States v. Craft, 535 U.S. 274 (2002) — applied Drye to hold that a husband's interest in a tenancy by the entirety was "property" subject to federal tax lien attachment, despite Michigan law treating the tenancy as indivisible
    • United States v. Rodgers, 461 U.S. 677 (1983) — pre-Drye but cited extensively; established framework for foreclosure on jointly-owned property
    • United States v. Bess, 357 U.S. 51 (1958) — earliest case applying federal-vs-state property framework to insurance policy cash value

    Practitioner application: when analyzing whether a federal tax lien attaches to a particular interest, the two-step analysis is: (1) what does state law give the taxpayer (the property right)? then (2) does federal law treat that interest as "property" or "rights to property" under §6321? This applies to jointly-owned property, trust interests (revocable vs irrevocable), community property, tenancy-by-entirety states, and interests in partnerships and LLCs.

    Section 3 · IRC §6323 — the public notice that perfects priority

    The NFTL is what makes the §6321 lien matter to third parties.

    The §6321 statutory lien exists between the taxpayer and the IRS by operation of law — but it is not effective against certain third parties without public notice. IRC §6323(a) establishes the rule: the lien is not valid against purchasers, holders of security interests, mechanic's lienors, and judgment lien creditors until the Notice of Federal Tax Lien (NFTL) is filed. The IRS files NFTL using Form 668(Y)(c).

    Filing location under IRC §6323(f) and Treas. Reg. §301.6323(f)-1:
    • Real property — recorded in the county where the property is situated (county recorder's office or county clerk)
    • Personal property — recorded in the county where the taxpayer resides
    • Federal lien registry — for certain categories under §6323(f)(4) Treasury regulations

    Per IRC §6323(g), an NFTL is effective for 10 years and 30 days from the date of assessment. The IRS may refile the NFTL within the one-year period ending 30 days after the lien becomes ineffective. Refiling extends the NFTL's effectiveness but does not extend the underlying §6502 CSED. Refiling is recorded on Form 668-F (Refile of Federal Tax Lien).

    The IRS sends the taxpayer Letter 3172 (Notice of Federal Tax Lien Filing and Your Right to a Hearing under §6320) within 5 business days of NFTL filing, per IRC §6320(a)(2). Letter 3172 triggers §6320 CDP rights — the taxpayer has 30 days to file Form 12153 requesting a CDP hearing on the lien filing. Equivalent Hearing under Treas. Reg. §301.6320-1(i)(2) is available within one year if the 30-day window is missed.

    Section 4 · Priority hierarchy

    Which creditors beat the IRS — and which don't.

    IRC §6323(a) establishes the four categories of third parties protected against an unrecorded §6321 lien: purchasers, holders of security interests, mechanic's lienors, and judgment lien creditors — each must have their interest perfected before NFTL filing to prevail against the IRS.

    Super-priorities under §6323(b) — ten categories prevailing over the federal tax lien even after NFTL filing:
    1. Securities (stocks, bonds in commercial transactions)
    2. Motor vehicles (purchasers without notice)
    3. Personal property purchased at retail
    4. Personal property purchased in casual sale
    5. Personal property subject to possessory lien
    6. Real property tax and special assessment liens
    7. Residential property mechanic's lien for repair/improvement ≤$1,000
    8. Attorney's liens
    9. Certain insurance contracts
    10. Passbook loans

    45-day rule under §6323(d): security interests in after-acquired property that arose pursuant to a written agreement entered into before NFTL filing have 45-day priority over the NFTL for additional security interests perfected within 45 days of NFTL filing. Critical for revolving credit and inventory financing. §6323(c) provides statutory super-priority protection for commercial transactions financing inventory and accounts receivable.

    Section 5 · IRC §6325(a) — the 30-day release mandate

    When the IRS must release the lien.

    IRC §6325(a)(1) imposes a mandatory release duty: the Secretary shall issue a certificate of release not later than 30 days after determining that the liability has been fully satisfied or has become legally unenforceable. The IRS issues Form 668-Z (Certificate of Release of Federal Tax Lien). Most NFTLs filed since 1982 contain self-releasing language under §6325(a) — the lien automatically self-releases upon CSED expiration without further IRS action.

    Critical distinction: a self-released NFTL remains visible in public records and on credit reports unless withdrawal under §6323(j) is also obtained. Practitioners pursuing full credit restoration must pursue both: (a) release confirmation (Form 668-Z); (b) withdrawal of the public notice (Form 10916(c)). Without withdrawal, the released lien continues to appear for up to 7 years under FCRA rules.

    Section 6 · IRC §6325(b) — property-specific discharge

    Removing specific property from the lien.

    IRC §6325(b) authorizes the IRS to discharge specific property from the federal tax lien while leaving the lien attached to all other taxpayer property. Discharge is the standard mechanism for completing property sales when the seller has an active federal tax lien. Filed via Form 14135 per Publication 783; IRS issues Form 669 (Certificate of Discharge). Processing time: 30-45 days; expedited handling available for documented time-sensitive transactions.

    §6325(b)(1)Remaining property double the liability

    Discharge granted if the FMV of remaining property subject to the lien is at least twice the sum of (i) the federal tax liability and (ii) all senior encumbrances. The 'rich taxpayer' discharge — applies when substantial other assets ensure the IRS interest is fully secured even after discharge of the specific property. Practitioner action: prepare detailed asset inventory with current appraisals demonstrating the 2× cushion.

    §6325(b)(2)(A)IRS receives value of its interest

    Discharge granted upon payment to IRS of an amount equal to the value of the government's interest in the specific property. Most-common discharge ground for home sales — at closing, sale proceeds pay the mortgage, then pay the IRS its calculated interest (property value minus senior encumbrances), then closing completes.

    §6325(b)(2)(B)IRS interest has no value

    Discharge granted when the IRS determines its interest in the specific property has no value — typically because senior encumbrances exceed property value. The IRS may consider forced sale value rather than FMV under Treas. Reg. §301.6325-1(b)(6), allowing normal selling expenses. Practitioner action: prepare HUD-1 or closing statement projection showing senior payoffs exceed property value, leaving zero proceeds for IRS.

    §6325(b)(3)Sale with proceeds held subject to lien

    Discharge granted under an agreement allowing the property to be sold with sale proceeds held in escrow subject to the lien. The sale completes; the proceeds are held; the IRS lien attaches to the proceeds rather than the property. Used when the procedural sequence requires sale completion before IRS satisfaction is determined.

    Section 7 · IRC §6325(d) — priority subordination

    Letting another creditor move ahead of the IRS.

    IRC §6325(d) authorizes the IRS to subordinate the federal tax lien to another creditor's interest without releasing or discharging the lien. Subordination keeps the IRS lien in place but moves the IRS's priority position below the subordinated creditor. Filed via Form 14134 per Publication 784; IRS issues Letter 4053 (Conditional Commitment to Subordinate) then Form 669 (Certificate of Subordination). Processing time: 30-45 days.

    §6325(d)(1) — Payment of subordinated amount

    Subordination granted upon payment to IRS of an amount equal to the value of the lien being subordinated. Dollar-for-dollar subordination — the IRS receives compensation equal to what it gives up in priority.

    §6325(d)(2) — Subordination facilitates collection

    Subordination granted when it will ultimately result in an increase in the amount realizable by the United States. The typical refinancing scenario — enabling financing that produces more net collection than forced sale.

    Section 8 · IRC §6323(j) — the four withdrawal grounds + Fresh Start

    Removing the public notice without releasing the lien.

    IRC §6323(j) authorizes withdrawal of the public Notice of Federal Tax Lien while the underlying §6321 statutory lien remains. Withdrawal differs fundamentally from release: withdrawal removes only the public notice; release extinguishes the lien. Most useful for credit restoration and title clearing — once the public notice is withdrawn, credit reporting agencies and title companies no longer see the lien. Filed via Form 12277; IRS issues Form 10916 (active lien) or Form 10916(c) (after release).

    §6323(j)(1)(A)Premature filing or filing not in accordance with IRS procedures

    NFTL was filed before §6303 demand satisfied, or violated published IRS administrative procedures (though not statutory requirements). Requires demonstration of procedural irregularity.

    §6323(j)(1)(B)Installment agreement

    Withdrawal granted where the taxpayer enters into an IA under IRC §6159 that explicitly provides for withdrawal, or where withdrawal is otherwise appropriate in the IA context.

    §6323(j)(1)(C)Withdrawal facilitates collection

    The most flexible and most-common ground. Removing the NFTL allows the taxpayer to obtain credit or operate a business in a way that produces collection revenue exceeding the public-notice value.

    §6323(j)(1)(D)Best interests of taxpayer and government

    Broad ground — basis for post-release withdrawal (after full payment and lien release) per IRS PMTA guidance. The IRS has concluded that post-release withdrawal is not legally prohibited and may be granted in its discretion.

    Fresh Start Initiative additions (2011):
    Withdrawal after release: tax liability satisfied; 3-year filing compliance history; current on estimated tax payments and federal tax deposits
    DDIA withdrawal under IRM 5.12.9.5: balance under $25,000; converted to Direct Debit IA; 3 consecutive DDIA payments completed

    Section 9 · IRC §6326 — erroneous NFTL filing

    When the lien shouldn't have been filed at all.

    IRC §6326 provides an administrative appeal of erroneous NFTL filing. The provision applies where at least one of the following is true: (a) the tax liability has been satisfied; (b) the tax liability was assessed in violation of deficiency procedures under §6213; (c) the assessment is barred by the running of the §6502 collection statute; or (d) the NFTL was filed against a person who is not the taxpayer.

    Filed by written request to the Collection Advisory Group identified on the NFTL, with supporting documentation. Upon approval, the IRS issues a release stating that the NFTL filing was erroneous — a procedurally distinct path from §6325(a) release. The §6326 release affirmatively acknowledges that the filing was erroneous, which can have evidentiary value in subsequent disputes or credit-restoration efforts.

    Most useful when: (a) the underlying assessment has been abated and the NFTL still shows; (b) the NFTL was filed against the wrong person (mistaken identity, name confusion); or (c) the NFTL was filed after CSED expiration. For wrong-person situations, the §6326 release can be limited to specific taxpayers identified on a joint NFTL.

    Section 10 · IRC §6331(b) — seizure authority

    Physical seizure of real and tangible property.

    IRC §6331(b) authorizes the IRS to seize tangible and real property to collect unpaid tax: "The term 'levy' as used in this title includes the power of distraint and seizure by any means." Seizure operates under the same statutory levy authority as wage and bank levies under §6331(a) — but applies to tangible/real property rather than intangible property held by third parties.

    Pre-seizure prerequisites per IRM 5.10.2:
    • • All standard pre-levy notice requirements satisfied — CP14 (§6303), CP504 (§6331(d)), LT11/Letter 1058 (§6330) for non-CDP-exempted property
    • • Form 13719 (Seizure Worksheet/Request) prepared and approved by the Director of Field Collection or designated managerial authority
    • • Form 668-B (Levy on Property) issued
    • • Coordination with Property Appraisal and Liquidation Specialist (PALS) for sale planning
    • • For private premises seizure under Policy Statement P-5-38, additional approval required
    • • For seizure of principal residence under IRC §6334(e)(1), U.S. District Court judicial approval required
    Seizure execution per IRM 5.10.3:
    • • Revenue Officer takes physical possession of personal property, or records levy against real property
    • Form 2433 (Notice of Seizure) delivered to the owner — the seizure date is the date Form 2433 is provided
    • Pub 1660 (Collection Appeal Rights) provided to taxpayer with Form 2433
    • • Copies of Form 2433 provided to senior lienholders identified through public records search
    • • Courtesy copy to Power of Attorney under Form 2848 (though direct delivery to POA does not satisfy IRC §6335(a) personal-service requirement)
    • 10-business-day CAP appeal window per Form 9423 instructions begins from Form 2433 delivery date

    Section 11 · IRC §6335 — public sale procedure

    From seizure to disposition.

    Notice of Sale under §6335(b) — per IRM 5.10.4:
    Personal property: Notice of Sale within 90 days of Notice of Seizure
    Real property: Notice of Sale within 180 days of Notice of Seizure
    Notice must include property description, time/place/manner/conditions of sale, appraised value, and minimum bid.
    Sale proceeds distribution under IRC §6342:
    1. Expenses of sale and seizure
    2. Senior liens (perfected before NFTL filing under §6323(a))
    3. Tax liability (with interest and additions)
    4. Excess to the taxpayer (§6342(b))

    §6335(f) Sale Request: the owner may request that seized property be sold within 60 days (or longer period specified by the owner). The IRS must comply unless compliance would not be in the best interest of the United States. Filed in writing to the PALS manager; response required within 30 days.

    Minimum Bid under §6335(e): established under Policy Statement P-5-35 (IRM 5.10.5), based on forced sale value (typically well below FMV). If no bidder meets the minimum, the IRS may purchase for the government at the minimum bid (property then goes to GSA) or postpone the sale. The purchaser at IRS auction receives Form 2435 (Certificate of Sale); for real property, Form 2434 (Deed) issues only after the 180-day §6337(b) redemption period expires.

    Section 12 · IRC §6337 — pre-sale and post-sale redemption

    Statutory right to recover seized property.

    §6337(a) — Pre-sale redemption (all property)

    Any person whose property has been levied upon may pay the amount due — unpaid tax + interest + penalties + costs of the seizure and any sale-related expenses — at any time prior to the sale. Upon payment, the property must be returned. The right applies to all property types (personal and real), and remains open until the IRS conducts the public auction.

    §6337(b) — Post-sale redemption (real property only)

    The owner of real property sold at IRS sale, or any person with an interest at the time of sale, may redeem within 180 days after the sale by paying the purchaser the amount paid at sale plus interest at 20% per annum. No post-sale redemption right exists for personal property. Redemption must be tendered to the purchaser; disputes over tender adequacy are resolved in federal court.

    Section 13 · IRC §6336 — expedited sale of perishable property

    When property cannot wait for standard sale procedure.

    IRC §6336 authorizes expedited sale of perishable goods — property which "if not speedily sold, will become greatly reduced in price or value by keeping, or which cannot be kept without great expense." Per Treas. Reg. §400.4-1(b)(2), examples include agricultural products, livestock, fresh inventory, and time-sensitive equipment. The §6336 procedure requires Director of Field Collection determination that the property qualifies as perishable, with a Perishable Goods Criteria and Sale Plan memorandum. The expedited procedure eliminates the 90/180-day Notice of Sale waiting period. The §6337(a) pre-sale redemption right remains available until the expedited sale occurs.

    Section 14 · Practitioner pitfalls

    Eight common errors.

    1. 1. Confusing release, discharge, and withdrawal. Release extinguishes the lien (§6325(a)). Discharge removes specific property from the lien (§6325(b)). Withdrawal removes the public notice while leaving the lien in place (§6323(j)). Different procedures, different documents, different legal effects.
    2. 2. Missing the 10-business-day CAP appeal window after seizure. Per Form 9423 instructions and IRM 5.1.9, the 10-business-day clock runs from the date Form 2433 is provided to the owner — not the date the owner discovers the seizure.
    3. 3. Treating self-releasing language as withdrawal. Most NFTLs filed since 1982 contain self-releasing language under §6325(a) — but the public notice remains in public records unless withdrawal under §6323(j) is also obtained. Full credit restoration requires both.
    4. 4. Failing to coordinate with Collection Advisory Group for §6325(b)/(d) applications. Discharge and subordination applications go to the Collection Advisory Group, not to the assigned Revenue Officer. Misdirected filings produce processing delays.
    5. 5. Confusing NFTL refiling effectiveness with CSED extension. NFTL refiling under §6323(g) extends the NFTL's effectiveness for another 10 years and 30 days, but does NOT extend the underlying §6502 CSED. A refiled NFTL can be valid while the underlying CSED has expired, making the assessment unenforceable.
    6. 6. Missing the Drye two-step analysis for complex property interests. State law determines what interest the taxpayer has; federal law determines whether that interest is 'property' or 'rights to property' under §6321. The disclaimer-prevention strategy rejected in Drye has been tried in many variations — the Craft and Rodgers frameworks extend attachment well beyond typical state-law expectations.
    7. 7. Applying discharge when subordination is the correct tool. Discharge (§6325(b)) is for property sales — the property is removed from the lien. Subordination (§6325(d)) is for new financing — the lien remains but the new creditor takes priority. For refinancing scenarios, subordination is typically the correct application.
    8. 8. Failing to mail Form 10916 to credit reporting agencies after withdrawal. NFTL withdrawal removes the public notice from county records — but it does not automatically update credit reporting agencies. Practitioners must mail Form 10916 or Form 10916(c) to Equifax, Experian, and TransUnion to produce credit report improvement.

    Section 15 · Practitioner FAQ (6 questions)

    Practitioner-grade questions.

    Does the Drye framework apply to irrevocable trusts?

    The Drye analysis turns on what rights the taxpayer has under state law. For irrevocable trusts where the taxpayer-settlor has no power to revoke, amend, or compel distribution, the taxpayer typically has no 'property or rights to property' to which the §6321 lien can attach. However, for trusts with ascertainable distribution standards (HEMS), retained income rights, or where the taxpayer is both settlor and beneficiary, the analysis is more complex. Courts have found lien attachment in some irrevocable trust contexts where the taxpayer retained meaningful rights.

    What is the difference between §6325(b) discharge and §6343 release?

    §6325(b) discharge removes specific property from the lien while preserving the lien against other property — used primarily for property sales. §6343 release of levy is the operative provision for returning levied property or releasing a levy on property — applies to situations where the levy itself should not have proceeded or where continued levy would cause economic hardship. §6325(b) is a lien remedy; §6343 is a levy remedy. Different statutory frameworks, different eligibility standards.

    How does NFTL refiling interact with the §6502 CSED?

    NFTL refiling under §6323(g) extends the NFTL's effectiveness for another 10 years and 30 days, but does NOT extend the underlying §6502 CSED. The CSED runs 10 years from the date of assessment under §6203 regardless of NFTL refiling. A refiled NFTL can still be valid while the underlying CSED has expired — making the assessment unenforceable even though the public notice remains. Practitioners should carefully distinguish NFTL effectiveness periods from CSED periods.

    What triggers §6320 CDP rights versus §6330 CDP rights?

    §6320 CDP rights are triggered by NFTL filing — the IRS must send Letter 3172 within 5 business days of NFTL filing, and the taxpayer has 30 days from Letter 3172 to file Form 12153 requesting a CDP hearing on the lien filing. §6330 CDP rights are triggered by pre-levy notice — the IRS sends LT11/Letter 1058 at least 30 days before levy, and the taxpayer has 30 days to file Form 12153 requesting a CDP hearing on the levy. Both suspend collection when timely filed.

    Can the IRS seize a taxpayer's primary residence?

    Yes, but with significant additional procedural requirements under IRC §6334(e)(1): seizure of a principal residence requires approval of a U.S. District Court judge or magistrate, and the IRS must show by a preponderance of the evidence that the liability is not collectible from other assets and that reasonable alternatives have been exhausted. Additionally, under IRC §6334(a)(13), the principal residence cannot be seized for liabilities of $5,000 or less.

    What is the minimum bid procedure and how does it affect seizure strategy?

    Under IRC §6335(e) and Policy Statement P-5-35 (IRM 5.10.5), the IRS establishes a minimum bid based on forced sale value — typically 80% of quick-sale value per the IRS PALS appraisal. If no bidder meets the minimum, the IRS may purchase for the government (property goes to GSA) or postpone the sale. Forced sale value is typically well below FMV; expedited resolution (redemption, IA, OIC) before the sale consistently produces better net outcomes for the taxpayer than IRS auction.
