SAVE LIVES. TAX BILLIONAIRES.

Can a One-Time Tax Really Help Protect Healthcare?

Yes. A one-time source of money can fund care over several years. Prop 40 creates a reserve fund and spending rules so its healthcare benefit is not confined to a single tax-payment day. [1]

VOTE YES ON PROP 40

Vote Yes on Prop 40. A patient who needs care now should not have to wait for Washington to deliver a different long-term solution.

The facts at a glance

The tax is one-time; the fund can support spending over several years. [1]

The statute allows revenues to remain in reserve for later allocation. [1]

Annual allocation ceilings are not promises of annual tax receipts. [1]

One-time tax does not mean one-day benefit

Prop 40 imposes its tax for the 2026 tax year. It allows payments over multiple years and places revenues in a reserve account. The Legislature can retain money in that reserve and allocate it under the measure’s annual spending limits. [1]

In ordinary terms, a one-time inflow can pay for more than one year of services. The source of the money and the period over which it is used are separate questions. The measure’s reserve structure is designed to make that separation possible. [1]

The measure names what near-term money can do

The healthcare account is meant to support coverage and providers and prevent or reduce facility closures and cuts in services. Those are practical uses of a temporary revenue source. A hospital’s ability to keep providing a service matters to the patients who need it during those years. [1]

It is not necessary to claim that one measure permanently solves every financing problem in order to value the care it can support. A treatment delivered, a service preserved, or a gap in access prevented can matter even when further policy work remains.

Collection and spending follow a timetable

The tax is generally payable with the 2026 income-tax return, to be filed in 2027, subject to the options in the statute. The standard installment choice spreads principal across five years and adds a charge to later unpaid balances. Qualifying deferrals may affect when some receipts arrive. [1]

The spending provisions therefore do not promise that the entire projected amount appears on election night. They permit annual allocations from the reserve, including up to $22.5 billion for healthcare and $2.5 billion for education and food assistance. Those are allocation limits, not guaranteed annual receipts. [1]

Why the timing matters for people

California’s health department has already issued a plan for federal eligibility and enrollment changes that put millions of California Medi-Cal members at risk. That is a concrete reason to prepare a response, rather than talk about the financing issue only as a distant hypothetical. [2]

New state money cannot erase a federal eligibility rule. It can give California additional means to support services and access within the law. The detail of that response belongs in implementation; the opportunity to create the funding source belongs to voters. [1]

An approved source of funding beats an unguaranteed future alternative

Voting Yes does not prohibit California from pursuing further reforms or pressing Congress to change course. The measure provides a particular funding tool with a defined tax base, fund, and public purposes. [1]

Our case is not that this is the last healthcare decision California will ever need to make. It is that protecting care now is critical—and that waiting for a perfect permanent answer is not a realistic plan to address immediate needs.

A few more answers

Does “one-time” mean billionaire taxpayers must pay in one installment?

No. They have the option of paying one installment or using the standard alternative, which is five annual installments of principal with a statutory charge on later unpaid balances. [1]

Can temporary funding and long-term reform both be useful?

Yes. They answer different questions. Prop 40 provides a specified funding source; supporting it does not require claiming that healthcare will never need another financing decision.
