Section 1 · The RRA 1998 framework
Congress created CDP to address taxpayer-rights abuses.
The Collection Due Process hearing framework was created by Section 3401 of the IRS Restructuring and Reform Act of 1998, Pub. L. No. 105-206, 112 Stat. 685 (1998) — known as RRA 1998. The legislation responded to congressional hearings in 1997 and 1998 documenting IRS taxpayer-rights abuses in collection enforcement. Congress enacted Section 3401 to ensure taxpayers received notice and a meaningful hearing before the IRS could levy on property or file a Notice of Federal Tax Lien.
The CDP provisions are codified at two parallel sections: IRC §6320 governs CDP rights upon NFTL filing; IRC §6330 governs CDP rights before levy. The provisions became effective for collection actions taken after January 18, 1999.
The legislative history at H.R. Rep. No. 105-599 (Conf. Rep.), at 263-267 (1998), articulates the statutory purpose: to "afford taxpayers adequate notice of collection activity and a meaningful hearing before the IRS deprives them of their property." Implementing regulations were promulgated by Treasury Decisions 8979 and 8980 on January 17, 2002, codified at Treas. Reg. §301.6320-1 and Treas. Reg. §301.6330-1. Significant amendments were promulgated on November 16, 2006.
Section 2 · IRC §6331(d) — the 30-day pre-levy notice
The IRS must give 30 days written notice before levy.
IRC §6331(d) requires the IRS to provide written notice at least 30 days before any levy action (subject to narrow exceptions for jeopardy assessments, state refund offsets, and disqualified employment tax levies). This 30-day pre-levy notice is statutorily required regardless of CDP rights — even where no CDP hearing right exists, the IRS must still provide §6331(d) notice before levy.
When the IRS issues a §6331(d) notice that also carries CDP rights under §6330, it does so by means of Letter 1058 (Field Collection cases assigned to a Revenue Officer) or LT11 (culminating notice in the Automated Collection System sequence). Both notices are titled "Final Notice of Intent to Levy and Notice of Your Right to a Hearing" and are legally identical CDP-eligible notices.
IRC §6330(a)(2) specifies that the notice must be given: (A) in person; (B) left at the taxpayer's dwelling or usual place of business; or (C) sent by certified or registered mail to the taxpayer's last known address. Per IRC §6330(a)(3)(B), the 30-day window runs from the date the CDP notice is sent (mailing date for mailed notices) — not from the date of receipt.
Section 3 · Form 12153 — procedural filing
What constitutes a timely, valid CDP request.
A CDP hearing is requested by filing Form 12153 (Request for a Collection Due Process or Equivalent Hearing) with the IRS office that issued the CDP notice — typically the address printed on Letter 1058 or LT11 itself. Filing with the wrong IRS office can result in the request being deemed untimely. Treas. Reg. §301.6330-1(c)(2), Q&A-C1 sets out the content requirements: the request must be in writing, signed, identify the taxpayer, identify the tax periods at issue, state the basis for the request, and propose specific collection alternatives or state the basis for any underlying-liability challenge.
Filing checklist — best practices
- File by certified mail with return receipt requested — proof of timely postmark
- File at least 5-7 business days before the deadline to allow for mailing delays
- Attach Form 2848 (Power of Attorney) if represented
- State all issues for the hearing specifically — Giamelli issue-exhaustion rule applies
- Propose specific collection alternatives with dollar amounts where possible
- For joint liabilities, both spouses must sign unless one is filing under innocent spouse relief
- Where underlying liability is contestable under §6330(c)(2)(B), state the basis with specificity
If the request is untimely (filed after 30 days but within one year), it is automatically treated as a request for an Equivalent Hearing under Treas. Reg. §301.6330-1(i)(2). The taxpayer may use Form 12253 (Withdrawal of Request) to withdraw a previously-filed request before the SO issues a determination.
Section 4 · IRC §6330(e)(1) — the collection hold
Timely filing automatically suspends collection.
IRC §6330(e)(1) — statutory text
"...if a hearing is requested under subsection (a)(3)(B), the levy actions which are the subject of the requested hearing and the running of any period of limitations under section 6502 (relating to collection after assessment), section 6531 (relating to criminal prosecutions), or section 6532 (relating to other suits) shall be suspended for the period during which such hearing, and appeals therein, are pending."
The collection suspension is automatic upon timely filing — no separate request, motion, or determination is required. From the moment the timely Form 12153 is postmarked through the conclusion of the CDP hearing and any Tax Court review, the IRS may not proceed with the proposed levy.
Suspension applies to:
- The proposed levy that triggered the CDP notice
- Running of the §6502 CSED (tolled)
- Running of §6531 criminal prosecution limitation
- Running of §6532 other-suits limitation
Suspension does NOT apply to:
- ✕Existing levies already in place — require separate §6343 release
- ✕IRS authority to file NFTL (governed by §6320)
- ✕§6331(d) notices for other tax periods
- ✕Non-levy collection actions (offsets, voluntary payments)
The interaction between CDP suspension and CSED tolling is procedurally important. IRM 25.6.1.7 confirms: the CSED is tolled from the date of the timely CDP request through the date of the Notice of Determination, plus the 90 days available to petition the Tax Court, plus any time during which a Tax Court petition is pending. This tolling can extend the CSED by 6-18 months in typical cases.
Section 5 · The Goza doctrine
Prior opportunity precludes underlying-liability challenge.
The most consequential limitation on CDP hearing scope is IRC §6330(c)(2)(B), which permits a taxpayer to "raise at the hearing challenges to the existence or amount of the underlying tax liability for any tax period if the person did not receive any statutory notice of deficiency for such tax liability or did not otherwise have an opportunity to dispute such tax liability."
Goza v. Commissioner, 114 T.C. 176 (2000)
First CDP case after RRA 1998. Howard Goza received a Notice of Deficiency but failed to petition the Tax Court within the 90-day window. On levy CDP, he attempted to challenge the underlying liability. Chief Judge Cohen held: prior receipt of a Notice of Deficiency precludes underlying-liability challenge, regardless of whether the taxpayer actually filed a petition.
Sego v. Commissioner, 114 T.C. 604, 611 (2000)
"Whether the underlying tax liability is properly at issue in a section 6330 administrative hearing depends on whether the taxpayer had an opportunity to challenge the liability, not whether the taxpayer acted upon that opportunity."
Also established: de novo review for liability issues; abuse of discretion for all other determinations.
Subsequent decisions refining the doctrine:
Bell v. Commissioner, 126 T.C. 356 (2006)
A prior CDP hearing itself constitutes 'prior opportunity' under §6330(c)(2)(B) — re-litigation precluded
Giamelli v. Commissioner, 129 T.C. 107, 113-114 (2007)
Issue exhaustion rule — issues not raised at the SO level cannot be raised for the first time on Tax Court review
Barnhill v. Commissioner, 155 T.C. 1 (2020)
§6330(c)(2)(B) analyzed without Chevron deference to IRS Appeals determination
The Diversified Group Inc. v. Commissioner, 166 T.C. No. 2 (2026)
Reaffirmed Goza framework; taxpayers without prior opportunity may challenge underlying liability including partnership-item adjustments
Practitioner application — prior-opportunity analysis
Before filing Form 12153, run a comprehensive prior-opportunity analysis for each tax period at issue. Pull all Notices of Deficiency, prior CDP hearing records, prior Appeals determinations, and audit reconsideration history. If a Notice of Deficiency was issued and the 90-day window expired without filing, the underlying liability is locked; the CDP hearing focuses only on collection alternatives. If no Notice of Deficiency was issued (typically Substitute for Return cases under IRC §6020(b), math-error adjustments under §6213(b), or assessable penalties), the underlying liability may be contested under §6330(c)(2)(B).
Section 6 · IRC §6330(c)(2)(A) — what may be proposed
Collection alternatives — the heart of most CDP hearings.
For the majority of CDP cases — those where the underlying liability is not contestable — the hearing focuses on collection alternatives proposed by the taxpayer under IRC §6330(c)(2)(A).
Installment Agreement — IRC §6159
Streamlined IA (under $50,000, all returns filed): minimal financial disclosure, IRM 5.14.5, typically approvable in days. Guaranteed IA under §6159(c) for balances under $10,000: mandatory approval. Full-payment IA for balances over $50,000: requires Form 433-A/F. Partial-pay IA (PPIA) under IRM 5.14.2: monthly payment less than full satisfaction; CSED continues to run; biennial review.
Offer in Compromise — IRC §7122
Three grounds: (i) doubt as to liability — separate framework; (ii) doubt as to collectibility — Form 656 + Form 433-A(OIC) demonstrating Reasonable Collection Potential below the assessment; (iii) effective tax administration (ETA) — economic hardship or compelling public policy. OIC submissions at CDP evaluated under Murphy v. Commissioner, 125 T.C. 301 (2005) framework.
Currently Not Collectible (CNC) Status
IRC §6343(e) is the statutory underpinning for CNC. Form 433-A demonstrating income does not exceed Allowable Living Expense (ALE) standards. CSED continues to run during CNC. Strategically optimal when within 3-4 years of CSED expiration.
Innocent Spouse Relief — IRC §6015
For joint-return cases, raised as a spousal defense under §6330(c)(2)(A)(i). If the SO denies relief, Equivalent Hearing on innocent spouse issue may proceed to Tax Court under the narrow §6015(e) jurisdictional grant — one of the few situations where Equivalent Hearings retain judicial review rights.
Section 7 · Closure of the hearing
The Settlement Officer's written determination.
The CDP hearing concludes with the Settlement Officer's issuance of a Notice of Determination under IRC §6330(c)(3). The Notice must address: (A) whether the IRS met all statutory and procedural requirements; (B) the issues raised by the taxpayer; and (C) the balance between efficient tax collection and the concern that any collection action be no more intrusive than necessary.
Under IRC §6330(d)(1), the taxpayer has 30 days from the date of the Notice of Determination to petition the United States Tax Court for review. The 30-day period for filing a Tax Court petition is jurisdictional and absolute — late filings will be dismissed for lack of jurisdiction. The petition may be filed electronically through DAWSON (the Tax Court's electronic filing system) or by mail under IRC §7502 timely-mailing rules.
Section 8 · IRC §6330(d)(1) — judicial review
Tax Court review of the Settlement Officer's determination.
De Novo Review
Applies when the underlying tax liability is properly at issue under §6330(c)(2)(B). Court considers the merits without deferring to the SO's determination. Taxpayer bears burden of proof under Tax Court Rule 142(a). Court may consider evidence outside the administrative record.
Abuse of Discretion Review
Applies in all other cases — collection-alternative determinations, appropriateness challenges. Standard per Sego, 114 T.C. at 610: whether the SO's determination was "arbitrary, capricious, or without sound basis in fact or law." Generally deferential to the SO. Court limited to administrative record per Robinette v. Commissioner, 123 T.C. 85 (2004).
Reversals under the abuse-of-discretion standard occur where: (1) the SO failed to consider an issue properly raised; (2) the SO based the determination on facts not in the administrative record; (3) the SO applied an incorrect legal standard; or (4) the SO's determination is contrary to controlling Tax Court precedent. Vinatieri v. Commissioner, 133 T.C. 392 (2009), is the canonical reversal example — the SO had refused to release a hardship levy citing unfiled returns; the Tax Court held this was abuse of discretion because §6343(a)(1)(D) does not condition hardship release on filing compliance.
Section 9 · Treas. Reg. §301.6330-1(i)(2)
The 1-year window when the 30-day deadline is missed.
If the 30-day CDP window is missed, the taxpayer may request an Equivalent Hearing under Treas. Reg. §301.6330-1(i)(2) within one year of the CDP notice date. The EH is conducted by Appeals using the same procedural framework as a CDP hearing — same Settlement Officer pool, same consideration of collection alternatives.
Three critical differences from timely CDP
No automatic collection suspension
IRC §6330(e)(1) applies only to timely CDP requests; IRS may levy during EH pendency
No Tax Court review rights
Except narrow §6015 (innocent spouse) and §6404 (interest abatement) carve-outs
No CSED tolling
The §6502 collection statute continues running during the Equivalent Hearing
Practitioners pursuing Equivalent Hearing should combine the request with: (a) express request to Collection that levy action be held pending the EH outcome; (b) Form 911 to TAS invoking IRC §7811 if any immediate levy threat exists; (c) express §6343 release request if an active levy is in place.
Section 10 · IRC §6320 — lien CDP
CDP rights upon NFTL filing.
IRC §6320 is the lien-CDP parallel to IRC §6330. When the IRS files a Notice of Federal Tax Lien (NFTL) under IRC §6321 and §6323, it must provide written notice within 5 business days under IRC §6320(a)(2). The notice is Letter 3172 (Notice of Federal Tax Lien Filing and Your Right to a Hearing Under IRC §6320). The taxpayer has 30 days from the date of Letter 3172 to file Form 12153.
The IRC §6320 CDP framework parallels §6330 with respect to hearing procedure, issues available, Settlement Officer evaluation, Notice of Determination, and Tax Court review. Lien-CDP hearings often focus on lien-specific remedies: lien withdrawal under IRC §6323(j) (where withdrawal will facilitate collection or is in the IRS's best interest), lien subordination under IRC §6325(d), lien discharge under IRC §6325(b), or DDIA lien withdrawal under IRM 5.12.9.5. Where both a levy CDP and lien CDP arise concurrently, Treas. Reg. §301.6330-1(b)(2) allows the IRS to consolidate them into a single hearing.
Section 11 · Practitioner pitfalls — where CDP engagements fail
Eight pitfalls that sink CDP cases.
Filing Form 12153 to the wrong IRS address.
Per Treas. Reg. §301.6330-1(c)(2), the request must be filed at the address printed on the CDP notice itself — not the general service center, not Appeals directly, not the local field office. Misdirected filings are routinely deemed untimely.
Measuring the 30 days from receipt rather than mailing.
IRC §6330(a)(3)(B) and IRM 5.1.9 use postmark date. The 30 days run from the date printed on the notice, not the date you opened the envelope.
Failing to raise all issues at the SO level.
Giamelli v. Commissioner, 129 T.C. 107, 113-114 (2007), holds that issues not raised at the SO level cannot be raised for the first time on Tax Court review. State every potentially relevant issue in the Form 12153 narrative.
Not running prior-opportunity analysis before challenging underlying liability.
Goza v. Commissioner, 114 T.C. 176 (2000), and Sego v. Commissioner, 114 T.C. 604 (2000), preclude underlying-liability challenges where any prior opportunity to dispute existed — including prior CDP hearings under Bell v. Commissioner, 126 T.C. 356 (2006).
Confusing CDP suspension with §6343 levy release.
CDP suspension under IRC §6330(e)(1) applies to proposed levies; it does not automatically release existing levies. Active levies require parallel §6343 release request.
Missing the 30-day Tax Court petition deadline under §6330(d)(1).
The 30 days runs from the date of the Notice of Determination. Filing in Tax Court on day 31 results in dismissal for lack of jurisdiction. The deadline is jurisdictional and absolute.
Treating the Equivalent Hearing as a substitute for timely CDP.
The Equivalent Hearing has no automatic collection suspension, no Tax Court review rights (with narrow §6015 and §6404 exceptions), and no CSED tolling. It is a procedural fallback, not an equivalent remedy.
Failing to coordinate CDP with parallel collection actions.
Where a wage levy or bank levy is already in place when CDP is filed, the engagement must run two parallel tracks: CDP-protected collection alternative negotiation, plus express §6343 release request to address the active levy.
