The Rules That Protect How Prop 40 Money Is Spent

Prop 40 contains spending rules, a protection against using funds to replace existing state funding, and annual reporting requirements. Voters can read those safeguards in the proposed law. [1]

VOTE YES ON PROP 40

Vote Yes on Prop 40. Raise money for healthcare with clear avenues for distribution and reporting duties—not an unrestricted pot of money.

The facts at a glance

The reserve fund has constitutional and statutory spending protections. [1]

Prop 40 money cannot replace existing state funding for the designated purposes. [1]

Prop 40 requires annual reports to the Legislature on the fund’s balances, allocations, and spending. [1]

The money goes into a defined reserve fund

The proposed constitutional provisions establish the Billionaire Tax Reserve Fund and restrict inconsistent borrowing, diversion, or appropriation. The related statute describes the accounts and the purposes for which their money can be used. [1]

That matters because raising revenue and protecting its use are different jobs. Prop 40 addresses both: it creates a tax on covered wealth and specifies the public purposes its proceeds are meant to serve. [1]

The allocation is written down

After administrative expenses, 90% of the funds are assigned to healthcare and 10% to K-14 public education and food assistance. Healthcare purposes include protecting coverage, supporting safety-net providers, and preventing or mitigating closures and service reductions. Education and food uses are separately described. [1]

The language in Prop 40 does not itemize or guarantee that a certain hospital will receive funding. However, the measure does set clear purposes — and limits — for how the funding from taxing billionaires can and cannot be used. [1]

New money must not replace existing support

Section 16355(d) says reserve-fund appropriations cannot justify reducing, eliminating, or failing to increase other state appropriations for healthcare, education, or food assistance. It separately bars using the measure’s funding to supplant existing state funds for those programs. [1]

Put simply: collecting a new dollar should not be treated as permission to pull away the old dollar. That is the purpose of the funding-protection provision. It does not prevent every future budget dispute, but it supplies an actual rule against substitution. [1]

Officials must account for the fund each year

Section 16355(f) requires the Department of Finance, in consultation with relevant agencies, to provide annual information to the Legislature. It covers the fund’s balance, estimates of revenue, proposed allocations, past expenditures, amounts kept in reserve, and certification that funding is not replacing otherwise appropriated support. [1]

Annual reporting is not a guarantee that misuse can never occur. It is a defined duty to account for the money and its use. Prop 40 expressly requires annual reporting to the Legislature. So a claim that the measure contains no transparency or reporting requirements omits provisions written into the measure itself. [1]

Administration has its own rules

The proposal provides an initial loan of up to $50 million for actual and necessary administration and specifies repayment and subsequent cost treatment. Administrative expenses are accounted for before the 90/10 split. The start-up loan is not a lifetime ceiling on all costs. [1]

The Franchise Tax Board also receives tax-administration responsibilities, including examination and enforcement. Spending oversight and tax collection are related but separate functions; both are present in the framework. [1]

What voters can insist on after passage

Voters can ask whether allocations fit the authorized purposes, whether existing support has been maintained as required, and whether the annual reports explain where the money went. Those questions follow directly from the measure’s structure. [1]

Our case for Yes is not that safeguards eliminate the need for scrutiny. It is that California can fund healthcare with explicit protections—and then hold implementation to those protections.

A few more answers

Does “accountability” mean premiums are guaranteed to fall?

No. The measure’s spending and reporting rules do not specify a guaranteed reduction in each person’s insurance premium. [1]

Where can I check the non-replacement and reporting provisions?

Read proposed Government Code sections 16355(d) and 16355(f), respectively, in the linked text of proposed laws. [1]

The people and institutions behind the evidence

Agency assigned fund-reporting duties; not a campaign endorser
