state auditor

The so-called billionaire tax has become one of the most contested California propositions in years, generating national interest and massive spending by opponents. It also has spawned two rival ballot measures.

Here’s a cheat sheet for sorting it all out.

Proposition 40

The basics

Proposition 40 would impose a one-time 5% tax on California billionaires’ assets. The tax applies to people with a net worth of at least $1 billion who resided in California on Jan. 1.

Impact

Ninety percent of the tax would fund healthcare, and 10% would go toward education and food assistance.

The tax would affect hundreds of billionaires whose net worth includes assets such as their businesses, stocks and other investments. Real property, pensions and retirement accounts generally would be excluded.

Proposition 41

It’s called the Improving Transparency, Effectiveness and Efficiency in California Government Act. But it is deeply connected to Proposition 40 and is funded by foes of the billionaire tax.

The basics

Proposition 41 requires the state auditor to review programs funded by proposed special taxes before they appear on the ballot. More importantly, it also prohibits new state taxes from being exempted from a voter-approved state spending limit.

Impact

The Legislative Analyst’s Office says passage of Proposition 41 could prevent Proposition 40, the proposed billionaire tax, from becoming law even if voters approve it. This could happen if Proposition 41 receives more “yes” votes than Proposition 40.

Proposition 42

Proposition 42 would limit the state’s ability to impose certain new taxes. But it’s more complicated and far-reaching than that description might sound. And, yes, it’s also backed by opponents of Proposition 40.

The basics

Proposition 42 would prohibit new taxes on “retirement holdings, individually owned assets, and other forms of personal savings” that take effect after Jan. 1, 2026. It also would bar retroactive taxes on past earnings unless the state is using revenue from the tax to respond to emergencies such as a fire or a flood.

Impact

The Legislative Analyst’s Office says Proposition 42 could nullify Proposition 40 because the two measures conflict with each other. If voters approve both, the one with the most “yes” votes generally would become law, the office says.

Dig deeper

The billionaire tax was pushed by the Service Employees International Union-United Healthcare Workers West and has some labor and progressive support, including from Sen. Bernie Sanders (I-Vt.) and the state Democratic Party. They say the tax is needed to help the less fortunate and that the super-rich can afford it. But key Democrats and some key unions are not supporting it.

Critics include some of California’s richest people, and they are spending a fortune to defeat it. They say it will hurt innovation and drive the wealthy out of the state, hurting the treasury.
