I need someone to check through an Inheritance Tax Map

Review and verify a global Inheritance Tax Map on my website. Systematically inspect each country entry and any linked subpages (e.g., Spain, France, UK, USA), cross‑checking current rules, thresholds, exemptions and tax rates. Identify and note discrepancies, outdated figures, or missing details, and provide concise, substantiated corrections with source citations. AI may be used but all updates must be validated for accuracy and currency.
