Plans to directly target billionaire fortunes through novel wealth taxes face significant practical and political hurdles, according to a report from The Guardian.
Policymakers are under growing pressure to tax immense wealth as the artificial intelligence boom creates more billionaires amid rising income inequality.

California represents the first state to attempt this, with voters deciding on a one-time 5% tax on fortunes exceeding $1 billion.
However, implementing a new wealth tax could exhaust political capital better spent on restoring existing tax mechanisms.
In 2024, the wealthiest 1% of Americans paid an average of about 31.5% in federal taxes and roughly 7.2% in state and local taxes.
This overall rate marks a decline of more than eight percentage points since the turn of the century.
With the top 1% reporting a total adjusted gross income over $3 trillion, restoring those eight points could generate nearly $300 billion annually.
Securing additional revenue can be achieved by closing the complex network of loopholes in the current tax schedule.
Loopholes and Their Impact
These loopholes offer preferential treatment to specific income types, reducing the overall tax liability of billionaires.
An analysis from the Yale Budget Lab shows the effective tax rate for top earners fluctuates between 45% and 3% based on income sources.
Data from 2024 shows only three advanced economies in the OECD collected revenue from recurrent wealth taxes: Norway, Spain, and Switzerland.
This is a sharp decline from 12 countries in 1990, and none of the remaining nations collect significant sums.
