Executive Summary
Rethinking California’s Reserve Policy. Reserves allow the state to ensure stable funding for its
services over time, even when revenue fluctuates unpredictably. Over the last few years, the state has
indeed experienced those significant fluctuations—large surpluses followed by significant deficits.
This volatility has prompted interest in changes to the state’s reserve policy. The Governor has proposed
two changes that, if passed by the Legislature, would go before voters. In this report, we assess those
proposed changes. We find that while they would improve upon the state’s reserve policy, they would not
reliably ensure stable funding for core services over time, and therefore further changes are warranted.
As such, we examine how much the state would need to save in reserves to maintain its core services during
future downturns.
What Is the Purpose of Reserves? The state will collect more in revenues than the cost of its core
service level in some years. In other years, it will collect less. Reserves help smooth the difference—funds

have constructed simulation-based tools—similar those used in insurance markets and the state’s pension
system—that use information about the past to forecast many different variations of the future. We report
findings across 50 years and thousands of these simulations.
Under Current Law, the State Can Cover One-Third of Funding Shortfalls. We find that the state’s
current constitutional rules for building reserves would allow the state to cover about one-third of funding
shortfalls. Put another way, if current law remained in place for the next 50 years, and without further saving
above this level, cuts to core services and/or tax increases would often be necessary.
Governor’s Proposal Improves Upon Current Law, but Further Improvements Are Warranted.
The Governor proposes two changes to the state’s reserve policy: (1) raise the cap on constitutional

AN LAO REPORT
deposits from 10 percent of General Fund taxes to 20 percent, and (2) make reserve deposits excludable
from the state appropriations limit. The Governor’s proposal improves upon current law—rather than
one-third, these changes would allow the state to cover about half of funding shortfalls over 50 years.
However, even with this change, reductions to core services or tax increases would still be common. In our
view, this means further improvements are warranted.
LAO Recommended Approach. We put forward two recommendations to improve reserve policy:
• Raise the Reserve Cap to 50 Percent by 2055. We first recommend the cap on constitutional reserve
deposits be raised from 10 percent to 50 percent of General Fund taxes. The increase could be phased
in over time: 20 percent to take effect immediately after the next statewide election, 25 percent in 2030,
and increasing by 5 percent every five years until the cap reaches a maximum of 50 percent in 2055.
• Two Options to Reach This Higher Threshold. If the cap is raised, the state would also need to set
aside more in reserve deposits to dependably reach this higher amount. There are many options for
doing this, but given the volatility in the state’s revenues, we think it is important to set aside much
more funds in years when revenues are surging, rather than setting aside somewhat more in every year.
We suggest two alternative mechanisms to accomplish this: (1) create new, more robust and flexible
deposit rules, or (2) keep existing rules in place, but change them to set aside more in capital gains
revenues in some years.
The figure below shows how the state’s reserve policy would perform under our recommended
alternatives. As it shows, we estimate our recommendations would allow the state to cover about
three-quarters of funding shortfalls over the next 50 years.
These Recommendations Are an Honest Reflection of Revenue Volatility. We understand that
building a reserve of this size—even if achieved over three decades—is a dramatic increase and well outside
the range of savings targets that have been contemplated by policymakers to date. Yet we do not view
these recommendations as overly cautious—to arrive at these estimates, we have used standard tools from
actuaries in pensions and insurance markets. These problems are also clear when California’s reserves are
compared to other states—California ranks near the top in terms of revenue volatility, but below average in
terms of reserves. As such, our recommendations are an honest reflection of the volatility in the state’s tax
system. That is, these changes would allow the state to enjoy the advantages of its current revenue structure
while protecting critical services for Californians for decades to come.

Reserve Policy and the Two Sides of the State Budget
State Budget Can Be Thought of in Two Distinct Parts. Functionally, California’s General
Fund budget is divided into two parts: one dedicated to K-14 education (about 40 percent of the
total) and another part that funds everything else (roughly 60 percent of the total). The reason for
this bifurcation is Proposition 98 (1988), which requires the state to set aside minimum amounts
of funding for schools and community colleges. With rare exceptions, the state must fund this
baseline regardless of other budget pressures. As a result, Proposition 98 creates a separate
budget for K-14 education that sits within the state’s larger budget.
Budget Conditions Can Diverge. The budget situation within Proposition 98 can
diverge sharply from the rest of the budget. For example, there can be a “surplus” within the
Proposition 98 budget (meaning that funding under the guarantee is more than sufficient to cover
the costs of existing educational programs) even as the rest of the General Fund faces a deficit.
That said, the conditions of these two parts of the budget tend to move together because, under
the constitutional formulas, funding for schools and community colleges will usually decline in
response to drops in revenues.
Schools and Community Colleges Have Separate System to Mitigate Revenue Volatility.
Revenue volatility is an issue for both sides of the budget, but each side also has distinct and
dedicated policies to address that volatility. For schools and community colleges, the main tool
is the state’s Public School System Stabilization Account (the Proposition 98 Reserve), which
requires the state to save more in reserves when revenues—especially those from capital gains
taxes—are surging. These funds must be used to supplement, but not supplant, Proposition 98
spending during a downturn. In addition, school and community college districts themselves hold
local reserves to manage unexpected cost increases, as well as state funding declines. Finally,
the state has used other tools like deferrals, which uses a principle similar to borrowing to help
smooth school spending through downturns.
This Report Does Not Address Reserve Policy for Schools. Given the division of the
budget and the separate reserve policies in place for schools and community colleges, this report
focuses only on the reserve policy for the rest of the budget. That is, the recommendations and
estimates in this report only address revenue volatility for the side of the budget that does not
include schools and community colleges, and this report does not speak to the adequacy of
preparedness for the Proposition 98 budget for revenue downturns.

Funding Shortfall Versus Budget Deficit
A budget deficit occurs when revenues are insufficient to pay for all of the state’s enacted
programs—including both core services and newly enacted or temporary programs. Because
of the state’s balanced budget requirement, a deficit must be closed before a budget can be
enacted. A deficit is related to, but distinct from, the concept of a funding shortfall described
in this report. The key conceptual difference is that a budget deficit will include the effects
of recently enacted one-time and temporary spending augmentations, whereas our aim in
measuring the state’s funding shortfall is to isolate the costs of the state’s core service level.
Further, budget deficits are highly influenced by estimation error and our method abstracts
away from these year-by-year particularities. Overall, we would describe funding shortfalls, as
measured in this report, as considerably smaller than budget deficits.

most volatile tax revenue systems in the country,
ranking fifth out of 50 states. However, using data
from the Fiscal Survey of States put together by
the National Association of State Budget Officers,
California’s rainy day fund balances are somewhat
below average. Figure 7 (on page 15) shows states’
rainy day funds as a share of total spending in 2024.
On this measure, California’s reserves rank 29 out
of 50. (In fact, Figure 7 likely overstates California’s
reserve balances compared to other states
because the data appears to include the SFEU in
the state’s rainy day fund balances, although it is
not a true rainy day fund.)
