Features
Identifies applicable tax treaties and relief mechanisms for specific transaction flows, including treaty benefits eligibility and relief from double taxation.
Evaluates transactions against OECD BEPS action items and domestic anti-avoidance rules (GAAR, BEAT, etc.) to identify compliance gaps.
Models PE risk across scenarios—fixed place, dependent agent, and service PE—with exposure quantification and mitigation strategies.
Traces transaction flows across territories, identifies tax residency, and maps withholding and filing obligations in each jurisdiction.
Generates transfer pricing analysis templates, comparable arm's-length range assessments, and contemporaneous documentation requirements.
Calculates optimal withholding treatment under treaty provisions, compares net vs. gross payments, and identifies relief-at-source opportunities.
Models tax impact under alternative transaction structures—entity type, payment timing, jurisdiction sequencing—with side-by-side comparison.
