About TaxInPangea

TaxInPangea indexes 902 bilateral tax treaties across 50 country networks, with every withholding rate traced to an official government source — IRS Table 1, HMRC's Double Taxation Agreement pages, CRA Part XIII guidance, Germany's BMF treaty publications, and 46 more tax authority sources.

The site is free to use, with no paywall and no registration required.

The Gap We Fill

If you need treaty withholding rates today, your options are limited. Free tools cover partial ground — Deloitte's DITS tracker covers roughly 65 countries, PwC publishes statutory rates without treaty detail. At the other end, enterprise platforms like IBFD start at $15,000+/year. There is no free, comprehensive, source-verified treaty rate reference for practitioners who need reliable data without an enterprise budget.

TaxInPangea fills that gap: broad coverage, official sources, and free access.

Who This Is For

  • Mid-market tax advisors who need to check treaty rates across multiple jurisdictions without an IBFD subscription.
  • Corporate treasury analysts modeling withholding tax on cross-border dividends, interest, and royalties.
  • Wealth managers advising clients with international income on pension and investment treaty benefits.

What We Offer

  • Withholding rates for dividends, interest, royalties, pensions, and social security across 902 bilateral treaties.
  • Treaty vs. statutory rate comparison showing the actual savings from treaty claims.
  • Free tools: a withholding tax calculator, a W-8BEN form assistant, and a treaty reclaim calculator.
  • Every rate linked to the official government publication it was extracted from.
  • Monthly automated verification against official sources to catch changes.

Data Quality

We extract rates exclusively from official government publications. Our data pipeline runs monthly verification checks against all 50 source URLs to confirm accessibility and data integrity. Treaty rates change infrequently — typically only when a treaty is renegotiated or a new protocol enters into force — but we verify monthly to ensure our data stays current.

Disclaimer

TaxInPangea is for informational purposes only and does not constitute tax, legal, or financial advice. We do not interpret treaties — we present the rates as published by official sources. Tax treaties are complex instruments with limitation-on-benefits clauses, tie-breaker rules, and domestic law overrides not fully captured in rate tables. Always consult a qualified tax professional for advice specific to your situation.
