Opinion: Taxing billionaires will help Californians keep their health coverage

August 2, 2026 - 21:19

A proposal heading to the California ballot this November could shift the burden of healthcare funding onto the state's wealthiest residents. Proposition 40, if approved by voters, would impose a new tax on billionaires, with the revenue directed specifically toward keeping hospitals open and slowing the rise of health insurance premiums.

Supporters of the measure argue that the state's healthcare system is in crisis. Rural hospitals have closed at an alarming rate over the past decade, and many urban facilities are operating on razor-thin margins. At the same time, families continue to see their monthly premiums climb year after year, even as deductibles grow larger. The new tax, they say, is a direct answer to that squeeze.

The mechanics are simple. The tax would apply only to individuals with a net worth above one billion dollars, a group that numbers fewer than two hundred people in the entire state. For those individuals, the annual levy would be modest relative to their wealth, but in aggregate, it is projected to raise several billion dollars each year. That money would be locked into a dedicated fund, meaning it cannot be diverted to other budget items.

Opponents have already pushed back, calling the measure a punitive and unconstitutional wealth tax. They argue that billionaires can easily relocate their residency or shift assets to avoid the levy, leaving the state with less revenue than projected. Others worry that the tax will hurt investment in California's tech and biotech sectors, which rely heavily on the very individuals the measure targets.

But backers of Proposition 40 point to public polling that shows strong support among likely voters, especially in working-class communities that have lost local hospitals. They also note that California already has a history of using targeted taxes on high-income earners to fund specific services, such as mental health programs.

The real question for voters is whether they trust the state to manage this money effectively. The measure includes strict oversight provisions, including annual audits and a public dashboard that tracks spending. If passed, the tax would take effect in 2026, with the first payments due the following year.

For now, the campaign is gearing up for a heated fight. Healthcare unions, nurses' associations, and several large hospital chains have endorsed the measure. On the other side, business groups and a handful of tech executives are funding opposition ads. The outcome will likely come down to whether voters see this as a fair way to fix a broken system or as a risky experiment that could drive wealth out of the state. Either way, the decision will have a direct impact on whether Californians can keep their coverage and whether their local emergency room stays open.
