From Steve Hilton Opposes California Billionaire Tax (Prop 40)

How could Proposition 40 affect the State of California's fiscal stability?

Possible What happens if… A possibility worth considering, not a forecast.

Proposition 40 could alter California's tax base and General Fund revenue. Proposition 40 proposes a one-time 5% tax on the net worth of California billionaires, which proponents say would raise tens of billions of dollars over several years primarily to fund Medi-Cal healthcare. However, opponents, including Steve Hilton, warn that the measure risks driving wealthy taxpayers out of the state if the tax goes into effect. This potential capital flight could negatively affect the state’s General Fund, offsetting the temporary revenue increase from the wealth tax.

While the measure is projected to raise tens of billions of dollars for state healthcare funding, opponents warn that the tax could drive billionaires out of the state, thereby affecting the state’s General Fund.

Why it matters

The State of California faces an imminent healthcare crisis due to federal cuts, which is driving the push for Proposition 40. The measure is intended to mitigate these losses and combat a projected doubling of the uninsured population by 2030 by providing a temporary infusion of cash.

However, the fiscal impact is complex. While the tax aims to provide a massive, temporary revenue increase, critics warn that this measure risks the steady stream of tax income from wealthy taxpayers, who could leave the state if the tax goes into effect, thereby undermining the state's long-term tax base.

What we don't know yet

What is the likelihood that billionaires would leave the state if Proposition 40 were passed?
Could the approval of Propositions 41 or 42 nullify Proposition 40, regardless of its vote outcome?

What would change this answer

The Legislative Analyst's Office provides a more precise estimate of the potential loss of General Fund revenue from capital flight.This would clarify the magnitude of the fiscal risk associated with the proposition.

The state legislature passes legislation that limits the scope of the tax or provides exemptions for high-net-worth residents.This would reduce the risk of capital flight and potentially stabilize the state's tax base.
