tax_compliance_multi
ActiveTool of @gapup/mcp-knowledge
Multi-jurisdiction tax compliance data for international SaaS, cross-border marketplaces and expat services. Five modes: (1) vat_lookup — validate EU VAT numbers live via VIES SOAP (27 EU countries) or UK VRN via HMRC; (2) sales_tax — US state sales tax rates, nexus thresholds (post-Wayfair 2018), digital goods taxability for all 50 states + DC; (3) gst — APAC GST/SST/consumption-tax rates for IN, SG, AU, NZ, MY, JP, KR, TH, ID, PH, VN with reduced rates and registration thresholds; (4) oss_ioss_eligibility — EU One-Stop-Shop and Import-OSS eligibility analysis (EUR 10k OSS threshold, EUR 150 IOSS per-consignment); (5) transfer_pricing_benchmark — OECD/JTPF operating-margin benchmarks by industry and country (20+ sectors, country-specific adjustments). Returns P0/P1/P2 compliance signals: P0=invalid VAT used for zero-rating, P1=taxable digital goods detected/audit risk, P2=filing deadlines/nexus alerts. Keyless — no API key required. Optional env: HMRC_VAT_API_KEY for UK VAT live validation. Cache TTL 24h.
