The Notice of Determination is the document that closes a Collection Due Process hearing. It articulates Appeals’ decision on the issues raised at the hearing, collection alternative, lien withdrawal, levy release, underlying liability where prior-opportunity-to-dispute did not exist, and sets the procedural timer on the taxpayer’s next decision. Within 30 days of the Notice of Determination, the taxpayer may petition the United States Tax Court for judicial review under IRC §6330(d)(1). After 30 days, the Notice becomes administratively final and judicial review is foreclosed.
The Tax Court appeal path is one of the most consequential procedural rights in tax collection, and one whose operational mechanics are frequently miscomputed even by experienced practitioners. Reading the Notice of Determination, identifying the issues preserved for review versus the issues waived, modeling the Tax Court’s standard of review for each issue, and deciding whether to petition within the 30-day window are four distinct analytical tasks that together determine whether a §6330(d) petition is filed correctly.
Petition-decision triage box (load-bearing):
1. Issue strength under the applicable standard of review. De novo issues (verification under §6330(c)(1), underlying liability under §6330(c)(2)(B) where preserved) are stronger candidates than abuse-of-discretion issues (collection alternatives, §6330(c)(3) balancing).
2. CSED extension cost. Petitioning extends the §6502(a) collection statute under §6330(e)(1) through Tax Court disposition + 90 days, longer if a petition is filed. Model the trade-off before filing.
3. Substantive remedy sought. Reversal of Appeals’ determination that collection action should proceed; re-determination of underlying liability where preserved.
4. Timing. 30 days from the Notice of Determination is strict; IRC §7502 timely-mailing-as-timely-filing controls.
The sections that follow walk each piece: what the Notice of Determination actually says, the §6330(d) appeal mechanics, the standard of review the Tax Court applies, and the post-Tax-Court appellate path.
What the Notice of Determination actually says
The Notice of Determination is issued under Treas. Reg. §301.6320-1(e)(3) (for lien-filing CDP hearings) or §301.6330-1(e)(3) (for levy CDP hearings). The Notice must address each issue properly raised by the taxpayer at the hearing under §6330(c)(2) and explain Appeals’ resolution. In practice, the Notice contains four substantive sections.
Verification of statutory requirements. Under IRC §6330(c)(1), Appeals must verify that the requirements of any applicable law or administrative procedure have been met, that the assessment was valid, that notice and demand under §6303 was issued, that the Final Notice of Intent to Levy was properly served. The Notice documents these verifications, generally in a separate section. Procedural defects identified at this stage can defeat the collection action regardless of the substantive issues.
Issues raised and considered. The Notice lists each issue the taxpayer raised under §6330(c)(2). For each issue, Appeals states whether the issue was sustained, partially sustained, or rejected. Common issues include collection alternatives (installment agreement, offer in compromise, currently-not-collectible status), spousal defenses under IRC §6015, challenges to the appropriateness of the proposed action, and procedural challenges. The clarity with which Appeals articulates the disposition of each issue determines what the Tax Court can later review.
Balancing analysis. Under IRC §6330(c)(3)(C), Appeals must consider “whether any proposed collection action balances the need for the efficient collection of taxes with the legitimate concern of the person that any collection action be no more intrusive than necessary.” The balancing analysis is the Appeals officer’s discretionary judgment, but it is reviewable by the Tax Court under an abuse-of-discretion standard. A well-articulated balancing analysis is the IRS’s strongest protection on Tax Court review; a perfunctory one creates vulnerability.
Final determination. The Notice concludes with the formal determination, whether the proposed collection action will proceed, whether a collection alternative has been accepted, whether the levy will be sustained or withdrawn. The determination is what the Tax Court reviews on appeal.
The §6330(d) appeal mechanics
Within 30 days of the date on the Notice of Determination, the taxpayer may file a petition with the United States Tax Court under IRC §6330(d)(1). The 30-day window is strict; the timely-mailing-as-timely-filing rule of IRC §7502 governs whether a petition is timely. A petition filed on day 31 is jurisdictionally defective and will be dismissed.
The Tax Court petition is filed under Tax Court Rule 330. The petition must identify the Notice of Determination by date and reference number, identify the taxpayer’s address, and articulate the issues for review. The Tax Court has standardized petition forms for §6330(d) cases, and the Court’s small-tax-case (“S-case”) procedure under §7463 may be available where the underlying tax dispute does not exceed $50,000.
Filing the Tax Court petition extends the CSED tolling under IRC §6502(a) that began with the CDP hearing. The tolling continues until the Tax Court’s decision becomes final, plus an additional 90 days. For a taxpayer who is approaching the 10-year collection statute, the CSED extension from a Tax Court appeal can add significant additional time to the government’s collection window, a factor that must be modeled before deciding to petition.
The IRS is barred from levying on the property at issue during the Tax Court’s consideration of the petition under IRC §6330(e)(1). The protection is durable but limited to the specific property and tax period under appeal.
The standard of review
The Tax Court applies different standards of review to different issues raised in a §6330(d) appeal, and the standard determines what the Court can do with the appeal.
Verification issues (§6330(c)(1)): Reviewed de novo for legal questions (whether the assessment was valid, whether notice was properly served) and for clear error on factual questions. De novo review means the Tax Court does not defer to Appeals’ conclusion; it reaches its own determination on the record.
Underlying liability issues (§6330(c)(2)(B)): Reviewed de novo where the taxpayer did not have a prior opportunity to dispute the liability and properly raised the issue at the CDP hearing. The Tax Court can re-determine the tax owed.
Collection alternatives and balancing analysis (§6330(c)(3)): Reviewed for abuse of discretion. The Tax Court defers to Appeals’ judgment unless the determination was arbitrary, capricious, or without sound basis in fact or law. This is a deferential standard that protects most reasonable Appeals decisions but does not protect manifestly unreasonable ones.
The Tax Court’s case law (under the modern Goza v. Commissioner, 114 T.C. 176 (2000), and Lunsford v. Commissioner, 117 T.C. 159 (2001), lineage) has refined the abuse-of-discretion standard to require Appeals to have considered relevant factors, applied the correct law, and articulated a reasoned basis for the determination. An Appeals determination that fails any of these tests can be reversed even under the deferential standard.
A practitioner deciding whether to petition the Tax Court must analyze the standard of review for each issue and assess the likelihood of success accordingly. Verification and underlying-liability issues, reviewed de novo, are stronger candidates for appeal than collection-alternative disputes reviewed for abuse of discretion.
The post-Tax-Court appellate path
A taxpayer (or the Commissioner) who is dissatisfied with the Tax Court’s decision on a §6330(d) case may appeal to the United States Court of Appeals for the geographic circuit of the taxpayer’s residence under 26 USC §7482. The circuit reviews legal conclusions de novo and factual findings for clear error. Circuit splits exist on several §6330 procedural questions, so the taxpayer’s circuit of residence can determine outcomes in marginal cases, but appellate strategy is downstream of the immediate Tax Court petition decision and should not displace it.
Issue-preservation: the warning that decides cases
The Tax Court’s review under §6330(d) is bounded by what the taxpayer raised at the CDP hearing. Issues not properly raised under §6330(c)(2) are generally unavailable on Tax Court review or are reviewed only for plain error. The Notice of Determination addresses the issues Appeals considered; issues the taxpayer surfaced for the first time in the petition rather than in the hearing record will typically be either dismissed for lack of jurisdiction or reviewed under a standard far more deferential than de novo. The collection alternative the taxpayer would have wanted to argue for, installment agreement at a particular monthly amount, offer in compromise at a particular dollar value, currently-not-collectible status on hardship grounds, must appear in the CDP hearing record at the Form 12153 stage, not for the first time in the Tax Court petition. The hearing record is the document the Tax Court reviews. Anything outside that record is at risk.
The decision to petition
The decision to file a Tax Court petition under §6330(d) comes down to three substantive questions and one timing question.
Issue strength. What is the likelihood of success on each issue under the applicable standard of review? De novo issues are stronger candidates than abuse-of-discretion issues. Verification defects and underlying-liability issues (where preserved) have the best track records.
CSED extension. What is the marginal CSED extension from petitioning? For a taxpayer with two years of CSED remaining, an additional 18-24 months of Tax Court consideration plus 90-day-finality plus appellate-court time is a meaningful give-back.
Substantive remedy. What does the taxpayer actually want from the Tax Court? Reversal of an Appeals determination that the proposed collection action should proceed is the typical relief. Determination of the underlying tax liability (where preserved) is the second most common.
Timing. The 30-day window from the Notice of Determination is strict. The decision to petition cannot be deferred past day 30.
Three specific taxpayer-risk failures arise from imprecise handling of the §6330(d) appeal window. Filing a petition past day 30 results in jurisdictional dismissal under Goza and its progeny, leaving the Notice of Determination administratively final with no judicial recourse. Filing without modeling the CSED extension can produce a marginal Tax Court outcome at the cost of substantial additional collection-statute time the IRS would not otherwise have. And asserting issues that exceed the §6330(c)(2) scope, for example, attempting to relitigate underlying liability where prior opportunity existed, produces partial dismissals that leave the remaining issues poorly framed for appeal.
The Notice of Determination, the §6330(d) petition mechanics, the standard-of-review analysis per issue, and the post-Tax-Court appellate path through the circuit courts together form the procedural architecture of a CDP appeal. The framework is well-developed in the case law and tractable for any practitioner who invests the time to learn it.
