Finance Tax Research
Purpose
Answer a federal, state, or international tax question with a defensible authority-based memo. The deliverable cites the controlling authorities in hierarchy order, applies them to the facts, reaches a tentative conclusion, and flags any uncertain-tax-position implications under FIN 48 / ASC 740-10.
Scope Constraints
- Produces a research memo and UTP recommendation; does not compute the tax provision (handoff to finance-provision once available) and does not file a return.
- Covers federal, state, and international (treaty-based) research; does not cover transfer-pricing benchmarking studies (specialized work).
- Does not constitute legal advice; the memo is a working paper for the tax function and outside counsel review.
Inputs
- The factual question, framed by the requester (with proposed transaction, dates, parties, amounts)
- Applicable jurisdictions (federal / state / foreign)
- Taxpayer entity classification (C-corp, S-corp, partnership, foreign branch, etc.)
- Relevant prior-year returns or positions for consistency
- Any open IRS / state examinations or letter rulings on point
- Authoritative research database access (BNA, CCH, RIA, Westlaw, Lexis)
- Materiality / risk threshold for UTP evaluation (per firm policy)
Input Sanitization
All inputs are read-only artifacts. No user-supplied values are interpolated into commands or file paths. Citations are verified against the authoritative source (not paraphrased from secondary sources) before being included in the memo.
Procedure
Progress Checklist
Step 1: Frame the Issue as a Yes/No or Quantitative Question
Restate the requester's question in research-memo form: a precise yes/no question ("Is the proposed transaction eligible for IRC §351 nonrecognition?") or a quantitative question ("What portion of the §163(j) limitation applies to interest on intercompany debt?"). Vague questions yield vague memos; pin the issue down before pulling authority.
Step 2: Identify Controlling Authority Hierarchy
Map the issue to the authority hierarchy:
- Statute — Internal Revenue Code (federal), state code, treaty text
- Regulations — Treasury Regulations (final > temporary > proposed)
- Revenue Rulings — IRS published interpretive guidance
- Revenue Procedures — IRS procedural guidance
- Case law — Tax Court, district court, circuit court, Supreme Court (note jurisdiction)
- Private Letter Rulings / TAMs — non-precedential but instructive
- Secondary sources — BNA portfolios, CCH explanations, treatises (citable for context, not authority)
Note where authorities conflict. Higher-tier authority controls.
Step 3: Pull Authorities and Quote Relevant Text
For each authority that bears on the issue:
- Full cite (e.g., IRC §351(a); Treas. Reg. §1.351-1(a)(1); Rev. Rul. 2003-51, 2003-1 C.B. 938)
- Quote the operative text verbatim (not paraphrased)
- Note the date adopted or modified, and any subsequent guidance
Step 4: Apply Each Authority to the Facts
For each authority, apply it to the taxpayer's facts:
- What the authority requires / permits / prohibits
- How the facts satisfy or fail each prong
- Where the facts are ambiguous, identify the assumption and flag it
Reach a tentative conclusion only after all bearing authorities have been applied.
Step 5: Identify UTP Implications under FIN 48 / ASC 740-10
If the conclusion involves an uncertain position:
- Apply the two-step FIN 48 test: (a) more-likely-than-not (>50%) recognition threshold, (b) measurement at the largest amount > 50% likely of being realized.
- If uncertain → recommend UTP reserve and quantify
- Flag whether the position requires Schedule UTP disclosure (taxpayer size threshold)
Step 6: Draft Research Memo
Memo structure: Issue / Conclusion / Authorities / Analysis / UTP Implication.
Memo is the workpaper of record; archive with full cite list and quoted authority text.
Compaction resilience: If context was lost during a long session, re-read the Inputs section to reconstruct the question and jurisdiction, check the Progress Checklist for completed steps, then resume from the earliest incomplete step.
Handoff
- If the conclusion drives a current- or deferred-tax computation, hand off to the future finance-provision skill for ASC 740 workpaper preparation.
- If the position triggers a UTP reserve, hand off to the Auditor specialist (and finance-controls-audit) for ICFR implications around tax controls.
- If the position implicates SEC disclosure (e.g., material UTP reserve, change in deferred-tax valuation allowance), hand off to RegRep / finance-disclosure-language for footnote and MD&A language.
