Tax treaty and exchange-rate sources
This page lists the tax treaty rates, withholding-tax rates, filing deadlines, and currency-conversion sources used by Tax Reclaim.
Information tool, not tax advice.
Historical exchange rates for tax calculations
Tax Reclaim uses the historical rate for the dividend or interest payment date. Frankfurter supplies blended exchange-rate data from central banks and official sources, including the European Central Bank, Bank of England, Bank of Japan, Banco de México, and Banco Central do Brasil. A blended rate can differ from a single authority fixing, so check the conversion method required by your tax authority.
Treaty rates
These are the treaty rates whose originating document we can link: the bilateral treaty text, or the national tax authority that published it. A rate the calculator resolves from a commercial tax summary is corroborated, not cited, and is not listed here.
- No treaty refund
- The source and residence countries have no treaty that provides a refund route.
- Treaty not effective
- A treaty is recorded, but it was signed and not in force or had ended for the relevant period.

Filing deadlines
These are the reclaim deadlines published by the tax authority itself. Deadlines we hold only from a commercial tax summary still drive the calculator and its countdown reminders, but they are not listed here.
Per-source provenance for the national statutory withholding rates is still being added. Until it lands, this page cites treaty rates and filing deadlines only.
How we keep this current
Treaty and deadline references are reviewed every tax year, and our continuous-integration pipeline blocks any release that ships without current-year rate data — stale figures fail the build before they can ever reach your claim.
