Stanford economists warn California billionaire tax could cost state $39 billion

Stanford economists Benjamin Jaros and Joshua Rauh have warned that California's proposed Proposition 40, a one-time 5% tax on billionaires, could result in a net loss for the state. Their analysis, published by the National Bureau of Economic Research, estimates the tax would collect approximately $30 billion, significantly less than the $100 billion proponents anticipate. The primary reason for this discrepancy is the potential for billionaires to relocate, which the economists project could lead to annual income tax revenue losses of $1 billion to $3.5 billion, ultimately outweighing the one-time tax proceeds.
