FinchipAIOrg Skill: Identify Issues in Notice of Deficiency
2. Failure modes the skill is correcting
- Reading the notice only for substantive tax positions and missing threshold defects in the notice itself, including internal inconsistency, missing elements, or computation errors.
- Failing to reconcile the cover-page deficiency with the supporting adjustment schedules, penalty computation, and any year-by-year totals.
- Treating all adjustments as equally strong instead of separating likely-sustained items from weak or contestable items.
- Overlooking filing deadlines, forum choice, and assessment-period issues that shape litigation posture.
- Discussing issues abstractly without tying each one to the amount at stake, the relevant source materials, and the downstream consequence for the client.
- Giving conclusions without naming the controlling tax authority that supports the analysis.
3. Legal frameworks / domain conventions that apply
- Notice of deficiency mechanics: A valid notice generally identifies the taxpayer, the taxable year, and the deficiency determination with enough clarity to allow petitioning. Check the face of the notice against the schedules and exam workpapers for consistency and completeness.
- Tax Court petition deadline: The 90-day petition period under I.R.C. § 6213(a) is central. If the notice was addressed outside the United States, evaluate the 150-day period where applicable. State the deadline prominently and treat it as a litigation-control item.
- Assessment and limitations periods: Analyze the normal assessment period under I.R.C. § 6501(a), then test whether any extension, suspension, fraud rule, substantial omission rule, or other exception could alter the year-by-year exposure.
- Penalty computations: Accuracy-related penalties generally turn on the amount of underpayment and the applicable statutory rate under I.R.C. § 6662 and related regulations. Verify the base, rate, and any stacking or alternative computation shown in the materials.
- Substantive adjustment authority: For each adjustment, identify the governing Internal Revenue Code provision, relevant regulation, and any leading judicial standard that controls the taxpayer’s best argument.
- Administrative and litigation posture: Compare Tax Court deficiency litigation with pay-and-refund alternatives, including settlement leverage, timing, discovery, and whether issues are better resolved through Appeals or in court.
- Alternative and affirmative tax positions: If the same facts may support additional deductions, credits, or basis adjustments, flag whether those positions can be asserted defensively or affirmatively in the petition or later filings.
- Credit-specific standards where implicated: If the materials involve a credit based on operations, shutdowns, or eligibility tied to government restrictions, test the factual predicate against the governing statutory and administrative standard before treating the credit as defensible.
4. Analytical scaffolds
Triage the notice
- Identify the taxpayer, tax years, asserted deficiencies, additions to tax or penalties, and petition deadline.
- Enumerate each year and each adjustment before analyzing them, unless only one item is truly in scope.
Reconcile the numbers
- Compare the cover-page deficiency to the schedule-level adjustments.
- Verify penalty calculations, bases, rates, and any cross-year carryover effects.
- Flag arithmetic mismatches, omitted items, or unsupported assumptions.
Issue-by-issue merits review
- For each adjustment, state the IRS position, the taxpayer’s best response, the governing authority, and the likely litigation posture.
- Close each issue by tying it to: the amount or exposure shown in the materials, any related schedule or document, and the practical consequence for the client.
Limitations and procedural defenses
- For each affected year, analyze the normal limitations period and any apparent extension or suspension.
- Identify any Notice of Deficiency defect, mailing issue, or timing issue that could affect jurisdiction or assessment.
Penalty analysis
- Identify the penalty type, the computation base, and the supporting facts for or against reasonable cause or other defenses.
- State whether the penalty appears overstated, underexplained, or unsupported on the current record.
Affirmative or offsetting positions
- Identify deductions, credits, basis increases, carryovers, or characterization arguments that may reduce exposure even if the IRS’s primary theory survives.
- Note whether the position is best raised in the petition, in amended pleadings, or in settlement discussions.
Strategic posture
- Compare petitioning the Tax Court with paying and pursuing a refund route.
- Address settlement leverage, Appeals options, timing pressure, and whether an early stipulation target is realistic.
Exposure framing
- Present low, medium, and high outcome ranges for aggregate exposure based on the strength of each issue.
- Separate the most defensible contested amount from weaker items that may need concession or compromise.
Authority support
- For each legal conclusion, cite the controlling statute, regulation, rule, or leading case that supports the proposition.
- Do not state a conclusion without naming the rule that makes it legally grounded.
5. Vertical / structural / temporal relationships
- Work year-by-year first, then aggregate across years only after each year’s deficiency, penalty, and limitations analysis is complete.
- Distinguish between the face of the notice, the computation schedules, and the exam materials; if they conflict, identify which document creates the inconsistency and whether it affects exposure or only presentation.
- Separate timing issues that affect jurisdiction or petition rights from substantive issues that affect tax liability.
- If multiple adjustments arise from the same factual cluster, analyze the shared facts once, then explain how each legal theory attaches differently to those facts.
- If a credit or deduction depends on a factual sequence over time, note the relevant dates, periods, or operational conditions before reaching the merits.
6. Output structure conventions
- Use a memorandum format with a short executive summary, then a year-by-year and issue-by-issue analysis.
- Start with the petition deadline and any jurisdictional or limitations red flags.
- Include a clear severity label for each issue using a consistent ordinal scale defined once near the start of the memo.
- For each issue, include: the IRS position, taxpayer response, controlling authority, exposure assessment, and downstream consequence.
- Quantify exposure in relative or document-based terms, but do not invent scenario-specific numbers not supported by the materials.
- Include an aggregate exposure range and identify the most defensible contested amount.
- End with a clearly labeled Recommended Actions section that gives an imperative action, the responsible role, and a timing anchor.
- Conclude with the recommended course of action and note whether Tax Court petitioning, Appeals engagement, or other procedural steps are preferred on the current record.
