us-cpa

us-cpa is a Python CLI plus OpenClaw skill wrapper for U.S. federal individual tax work.

Current Milestone

Milestone 2 now adds the first tax-year corpus layer:

• deterministic cache layout under ~/.cache/us-cpa by default
• fetch-year download flow for the bootstrap IRS corpus
• source manifest with URL, hash, authority rank, and local path traceability
• authority ranking hooks for IRS materials and future primary-law escalation

Tax logic, case workflows, rendering, and review logic are still pending.

Tax-Year Cache

Default cache root:

~/.cache/us-cpa

Override for isolated runs:

US_CPA_CACHE_DIR=/tmp/us-cpa-cache skills/us-cpa/scripts/us-cpa fetch-year --tax-year 2025

Current fetch-year bootstrap corpus for tax year 2025 is verified against live IRS irs-prior PDFs for:

• Form 1040
• Schedules 1, 2, 3, A, B, C, D, SE, and 8812
• Form 8949
• General Form 1040 instructions and selected schedule/form instructions

Interaction Model

• question
  • stateless by default
  • optional case context
• prepare
  • requires a case directory
  • if none exists, OpenClaw should ask whether to create one and where
• review
  • requires a case directory
  • can operate on an existing or newly-created review case

Planned Case Layout

<case-dir>/
  input/
  extracted/
  return/
  output/
  reports/
  issues/
  sources/

Current implementation writes:

• case-manifest.json
• extracted/facts.json
• issues/open-issues.json

Intake Flow

Current extract-docs supports:

• --create-case
• --case-label
• --facts-json <path>
• repeated --input-file <path>

Behavior:

• creates the full case directory layout when --create-case is used
• copies input documents into input/
• stores normalized user-statement facts in extracted/facts.json
• appends document registry entries to case-manifest.json
• stops with a structured issue and non-zero exit if a new fact conflicts with an existing stored fact

Output Contract

• JSON by default
• markdown available with --format markdown
• question supports:
  • --style conversation
  • --style memo
• question, prepare, review, extract-docs, render-forms, and export-efile-ready still emit scaffold payloads with status: "not_implemented"
• fetch-year emits a downloaded manifest location and source count

Question Engine

Current question implementation:

• loads the cached tax-year corpus
• searches a small IRS-first topical rule set
• returns one canonical analysis object
• renders that analysis as:
  • conversational output
  • memo output
• marks questions outside the current topical rule set as requiring primary-law escalation

Current implemented topics:

• standard deduction
• Schedule C / sole proprietorship reporting trigger

Scope Rules

• U.S. federal individual returns only in v1
• official IRS artifacts are the target output for compiled forms
• conflicting facts must stop the workflow for user resolution

Authority Ranking

Current authority classes are ranked to preserve source hierarchy:

• IRS forms
• IRS instructions
• IRS publications
• IRS FAQs
• Internal Revenue Code
• Treasury regulations
• other primary authority

Later research and review flows should consume this ranking rather than inventing their own.
