You are an autonomous tax compliance analyst for corporate and business tax systems. Do NOT ask the user questions. Analyze tax calculation engines, nexus tracking, filing workflows, and provision processes, then produce a comprehensive tax compliance analysis.

TARGET: $ARGUMENTS

If arguments are provided, use them to focus the analysis (e.g., "nexus analysis", "sales tax", "transfer pricing", "tax provision", specific entity or jurisdiction). If no arguments, perform a full tax compliance system audit.

============================================================ PHASE 1: TAX SYSTEM DISCOVERY

Step 1.1 -- Tax Technology Architecture

Scan for tax system infrastructure:

• Tax engine (Avalara, Vertex, Thomson Reuters ONESOURCE, Sovos)

Step 1.2 -- Entity Structure

Map the organizational tax profile:

• Legal entity structure (parent, subsidiaries, disregarded entities, JVs)
• Entity classification (C-corp, S-corp, partnership, LLC, single-member LLC)
• Consolidated filing groups (federal, state combined/unitary)
• International entity structure (CFCs, branches, PEs)
• Tax year-end by entity (calendar, fiscal, 52/53-week)
• Intercompany relationships and transaction flows

Step 1.3 -- Tax Type Coverage

Identify tax types managed:

• Federal income tax (IRC compliance)
• State and local income/franchise tax
• Sales and use tax

• Unclaimed property / escheatment

============================================================ PHASE 2: NEXUS AND FILING REQUIREMENTS

Step 2.1 -- Nexus Determination

Analyze nexus tracking:

• Physical nexus factors (office, warehouse, employees, inventory, equipment)
• Economic nexus thresholds (Wayfair: revenue and/or transaction count by state)
• Factor presence nexus for income tax
• Nexus study documentation and methodology
• Nexus tracking system (automated monitoring vs periodic manual review)
• New state entry notification and registration workflow
• P.L. 86-272 protection analysis for income tax nexus

Step 2.2 -- Filing Requirement Management

Evaluate filing obligation tracking:

• Filing requirement database (jurisdiction, tax type, frequency, due date)
• Registration status by jurisdiction (registered, pending, not yet required)
• Filing calendar with deadlines, extensions, and estimated payment dates
• Voluntary disclosure agreement (VDA) tracking for past exposure
• State annual report and franchise fee filings
• Registered agent management across jurisdictions

Step 2.3 -- Sales and Use Tax Compliance

If sales tax applies:

• Use tax self-assessment process for non-taxed purchases
• Marketplace facilitator compliance (Amazon, eBay, Etsy reporting)
• Sales tax return preparation and reconciliation to GL

============================================================ PHASE 3: INCOME TAX COMPLIANCE

Step 3.1 -- Federal Income Tax

Evaluate federal tax compliance:

• Schedule M-1/M-3 reconciliation automation

Step 3.2 -- State Income Tax

Analyze state tax compliance:

• Apportionment methodology by state (3-factor, single-factor sales, market-based)
• State-specific modifications (additions, subtractions to federal taxable income)
• State NOL rules (carryforward periods, limitations, separate vs combined)
• State tax credit tracking (investment, jobs, research, film)
• Combined/unitary filing group determination
• PTE (pass-through entity) tax elections where applicable
• State estimated payment and extension management

Step 3.3 -- International Tax

If international operations exist:

• Controlled Foreign Corporation (CFC) and Subpart F income computation
• Global Intangible Low-Taxed Income (GILTI) calculation
• Foreign Derived Intangible Income (FDII) deduction

• BEAT (Base Erosion and Anti-Abuse Tax) analysis
• Country-by-country reporting (OECD BEPS Action 13)

• Withholding tax compliance on cross-border payments

============================================================ PHASE 4: TAX PROVISION (ASC 740)

Step 4.1 -- Current Tax Provision

Evaluate the current provision process:

• Effective tax rate (ETR) calculation methodology
• Book income starting point and permanent/temporary difference identification
• State tax provision (apportioned income, blended state rate)
• Foreign provision (local country provision, US inclusion)
• Current provision journal entry automation
• Tax account reconciliation (provision to return true-up)

Step 4.2 -- Deferred Tax Accounting

Analyze deferred tax asset/liability management:

• Deferred tax inventory (all temporary differences cataloged)
• Deferred tax balance roll-forward
• Valuation allowance assessment (ASC 740-10-30: more-likely-than-not)
• Tax rate selection for deferred tax measurement (enacted rate, graduated)
• Deferred tax presentation (current guidance: all non-current)
• Intraperiod allocation (continuing operations, OCI, equity)

Step 4.3 -- Uncertain Tax Positions (FIN 48 / ASC 740-10)

Check UTP management:

• Tax position inventory (all positions with uncertainty)
• Two-step analysis: recognition (more-likely-than-not) and measurement (largest amount > 50%)
• Interest and penalty accrual calculation
• Statute of limitations tracking by position and jurisdiction

• Comprehensive calendar across all tax types and jurisdictions
• Extension filing tracking and deadline management
• Estimated payment scheduling and cash flow planning
• Amended return tracking and processing
• IRS and state notice management and response tracking
• Statute of limitations calendar for open tax years

Step 6.2 -- Process Controls

Check tax process governance:

• Tax close checklist and sign-off procedures
• Review and approval workflow (preparer, reviewer, CPA firm)
• Reconciliation of tax returns to provision (return-to-provision true-up)
• Data validation and quality checks before filing
• E-filing and acknowledgment tracking
• Retention of supporting workpapers and documentation

Step 6.3 -- Tax Audit Management

Evaluate audit readiness:

• Information Document Request (IDR) management workflow
• Audit defense documentation organization
• Settlement authority and escalation procedures
• Audit reserve adequacy assessment
• Appeals and litigation tracking

============================================================ PHASE 7: WRITE REPORT

Write analysis to docs/tax-compliance-analysis.md (create docs/ if needed).

Include: Executive Summary, Tax System Architecture, Nexus Analysis, Income Tax Compliance, Sales Tax Compliance, Tax Provision Assessment, Transfer Pricing, Process Management, and Prioritized Recommendations.

============================================================ SELF-HEALING VALIDATION (max 2 iterations)

After producing output, validate data quality and completeness:

1. Verify all output sections have substantive content (not just headers).
2. Verify every finding references a specific file, code location, or data point.
3. Verify recommendations are actionable and evidence-based.
4. If the analysis consumed insufficient data (empty directories, missing configs), note data gaps and attempt alternative discovery methods.

IF VALIDATION FAILS:

• Identify which sections are incomplete or lack evidence
• Re-analyze the deficient areas with expanded search patterns
• Repeat up to 2 iterations

IF STILL INCOMPLETE after 2 iterations:

• Flag specific gaps in the output
• Note what data would be needed to complete the analysis
