AN LAO REPORT
Introduction
Few topics are more challenging for policymakers than taxation. Taxes fund public services that Californians
use every day, but they also exact costs on families and businesses. This presents difficult questions for
policymakers. Who should pay taxes, how much, and in what form? At what point do the costs of taxes exceed
the public benefits of the services they pay for? The Legislature often has turned to our office for guidance on
these questions and, most recently, sought that guidance as part of last year’s budget deliberations. These
questions, however, have no objective answer. Rather, policymakers must attempt to strike a balance that they
believe best reflects Californians’ values. As the Legislature’s nonpartisan advisor, we cannot tell policymakers
where that balance should be struck. We can, however, offer context and information to help policymakers sort
through these difficult choices.
One such type of information is the range of options available to raise or lower taxes and the trade-offs each
of those options presents. What are the costs of raising taxes or the benefits of cutting them? Who would pay
those costs or receive those benefits? How stable and reliable would the resulting changes in revenue be? With
this information in hand, policymakers are better positioned to weigh changes in taxes against changes in public
services. The aim of this report is to provide that information.
The report proceeds in four sections. The opening section discusses our analytical approach and provides
guidance on interpreting our findings. The other three sections detail various tax options. First, we examine
tax increase options that would each raise between $1 billion to $3 billion per year. Next, recognizing that
policymakers soon will need to grapple with the expiration of temporary income tax rates put in place by
Proposition 55 (2016), we turn to options that raise around $10 billion to $15 billion per year. Finally, we look at
options to lower taxes by $1 billion to $3 billion per year.
Understanding Our Approach
This report lays out a range of options for raising and lowering taxes and compares those options to each other
on a variety of criteria. This section describes the process that went into developing our findings.
Rubric
To evaluate tax options, we use a rubric with five categories: budgeting, economy, taxpayer experience,
progressivity, and fairness. Each of these categories represents an important area of consideration for
policymakers when evaluating tax options. No category is necessarily more important than another. Different
policymakers will weigh these considerations differently based on their values and priorities. For example,
some may prioritize options that are highly progressive. Others instead may favor options that improve stability
and predictability in state budgeting. Our work does not aim to resolve these differences. Instead, we offer our
assessment of how various options rank within each category. Policymakers may then use that information to
decide which options they think are best. Below, we describe each category and discuss the criteria used to arrive
at our rankings.
Budgeting. The budgeting category focuses on three main criteria:
• Growth. How much will the new revenues (tax relief) grow over time? Will that growth keep up with the
overall economy? Options that grow faster rank higher.
• Stability. How much will the new revenues (tax relief) fluctuate from year to year? Options that fluctuate less
rank higher.
• Predictability. How well will we be able to predict the initial revenues when the change is first put in place?
How well will we be able to predict these revenue changes from year to year? Options that are more
predictable rank higher.

Economy. Taken in isolation—that is, ignoring the benefits of the public services that taxes pay for—tax
increases come with economic costs. Similarly, tax cuts bring economic benefits. This category attempts to
gauge those economic effects. Overall, options that likely have smaller economic costs (larger economic benefits)
rank higher. Taxes can affect the economy through many channels. Our review focuses on potential effects in
three main areas:
• Jobs. How much could the tax increase reduce employment? Or how much could the tax relief
increase employment?
• Disposable Income. How much could the tax increase reduce real disposable incomes? Or how much
could the tax relief increase real disposable incomes? Real disposable incomes decline if wages go down
or prices go up.
• Innovation. How much could the tax increase reduce productivity growth or consumer product innovation?
Or how much could the tax relief boost productivity and innovation?
Taxpayer Experience. The taxpayer experience category focuses on how difficult and expensive it would
be for taxpayers to comply with the new tax or to receive the new tax relief. Relatedly, how easily can taxpayers
understand the tax change and how likely are they to comply voluntarily?
Progressivity. The progressivity category looks at two main criteria, in order of importance:
• “Ordinary” Californians. What share of the new tax costs (tax relief) fall on ordinary Californians (defined
as individuals earning $250,000 or less and couples earning $500,000 or less)? Options that place a smaller
share of costs (larger share of benefits) on ordinary Californians rank higher.
• Overall Progressivity. Do the new tax costs increase as the taxpayer’s income increases? Or does the tax
relief decrease as the taxpayer’s income increases? The more costs increase (decrease, in the case of tax
relief) as income increases, the higher the option ranks.
Fairness. There are many, often subjective, concepts of fairness. For this reason, evaluating a comprehensive
definition of fairness is beyond the scope of this project. Instead, we focus on two narrower criteria that we think
better lend themselves to objective evaluation:
• Similar Treatment. Could the tax change result in incidental or unintentional dissimilar treatment of similar
taxpayers? Conversely, could the change lessen or eliminate an existing dissimilar treatment among
similar taxpayers?
• Historically Disadvantaged Groups. Does the tax change disproportionately burden
historically disadvantaged groups? Conversely, does the change lessen or eliminate an existing
disproportionate burden?
Some Important Considerations Fall Outside Our Rubric. Some considerations that will factor into
policymakers’ decisions about taxes are not included in our rubric. These considerations include the difficulty
of enacting the changes, public opinion, or more expansive notions of fairness. The exclusion of these
considerations does not mean they are unimportant or that policymakers should ignore them. Rather, we cannot
offer guidance because they are outside the scope of nonpartisan analysis.
Selection of Options
Our process for selecting options to include in this report involved a handful of key considerations. First,
we aimed to demonstrate the variety of options available to policymakers. We do, however, limit the options to
changes in taxes paid, excluding options like refundable tax credits. Second, we excluded options if it appeared
they (1) would not begin raising ongoing revenue within a few years, (2) raised significant legal concerns, or
(3) could not be feasibly administered without extraordinary costs. Finally, to keep the scope of the report
manageable, we excluded options we anticipated would score comparatively poorly across our rubric.

Evaluation Process
Consensus-Based Rankings. Our goal is to use the best available evidence to rank various tax options
on the defined criteria of our rubric. We acknowledge that this exercise necessarily involves judgement. Two
different researchers may reasonably disagree on which evidence is the strongest or how best to interpret
certain statistics. Further, definitive evidence rarely exists on the questions we are considering, requiring the
use of secondary evidence and rules of thumb. To mitigate this issue, we used a consensus-based approach.
Our office’s team of five economists reviewed the available evidence on each of the tax options. Following those
reviews, each economist independently ranked the options using our rubric. Our results reflect the consensus of
those rankings.
Evidence Reviewed. Our team reviewed a variety of evidence, including:
• Tax Data. Historical data on tax collections; detailed taxpayer data from the state’s tax agencies.
• Other Official Data. Census data on demographic and economic characteristics of Californians; various
economic data from the U.S. Bureau of Economic Analysis, Bureau of Labor Statistics, and others.
• Academic Research. A variety of academic studies, a selection of which is listed at the end of the report.
• Established Theory. Theories about how the economy works that have withstood scrutiny and have been
corroborated by real-world experience.
Making the Best of Limited Evidence. The quality of evidence varies across the options we evaluated and
the criteria we used for evaluation. One topic for which clear evidence is rare is the economy. Only in very limited
cases are rigorous studies available to speak directly to the effect of the taxes on jobs, real disposable incomes,
or innovation. Where this type of evidence is lacking, we supplemented our analysis with secondary evidence:
• How Much of the Costs and Benefits Are Shifted Out of State? There are many ways that the costs
or benefits of a tax change can go to people and businesses located elsewhere. For example, people
may pay a tax for something they do while in the state temporarily, like a tourist paying sales tax on their
vacation purchases. Multistate businesses may recoup part of a tax by raising prices for customers in other
states. People and businesses sometimes can shift their state tax costs to the federal government through
deductions against federal taxes. When more costs are shifted out of state, this likely reduces the risk of
negative economic outcomes. Similarly, when more benefits of tax relief go out of state, this reduces the
potential for a boost to the state’s economy.
• Does the Tax Change Encourage People or Businesses to Act Unproductively or Inefficiently? Taxes
can encourage people and businesses to take actions that are aimed primarily at reducing tax payments.
Often these actions can be unproductive or inefficient. For example, if a manufacturing business has to pay
taxes for buying machinery from another business, they may decide to make that machinery in house, even
if it costs them more to do so. These kinds of actions can be a drag on the economy. When we find evidence
that a certain tax change encourages these kinds of actions, we assume a higher risk of negative economic
outcomes.
• How Much Does the Tax Change Discourage Productive Economic Activity? Taxes can discourage
people and businesses from taking actions that grow the economy. For example, taxing the income of small
business owners may discourage people from starting businesses. Similarly, taxing investment returns may
discourage people from funding innovative ventures. When we find evidence that these kinds of responses
are larger for a certain tax change, we assume a higher risk of negative economic outcomes. One common
rule of thumb that we employ is that these kinds of responses tend to intensify as tax rates get higher.
• How Much Does the Tax Fall on Low-to-Middle-Income Taxpayers? While not conclusive,
decent evidence suggests that taxes on low-to-middle-income taxpayers are a greater drag on the
economy than taxes on high-income taxpayers. Consistent with this, we use the progressivity of the
tax change to supplement any evidence in the other categories above. Where two options score
similarly on other evidence, we assign a lower economy ranking to the option that falls more on
low-to-middle-income Californians.

Interpreting the Results
Options Ranked in Tiers. Our evaluation assigns each tax option to a relative tier in each of the categories of
our rubric. For example, an option that is among the most progressive is assigned to the top tier of progressivity,
while an option that is among the most regressive is assigned to the bottom tier. The rankings include four tiers for
options to raise taxes by $1 billion to $3 billion. In contrast, because we present fewer options to raise $10 billion
to $15 billion, those rankings include just three tiers. Similarly, the rankings of options to lower taxes by $1 billion to
$3 billion include three tiers. The results for fairness are different. Instead of tiers, we report one of three findings:
(1) lessens existing fairness concerns, (2) neutral, or (3) raises new fairness concerns. Our results are presented
graphically, as explained in Figure 1 (next page).
Rankings Are Relative. All our rankings are relative. That means we are not scoring the options against
an ideal standard. Instead, our rankings are based only on how an option compares to the other options. To
understand why this is important for interpreting our results, consider the economy. If a tax increase is in the top
tier for economy, it does not mean it has no economic costs. If a tax increase is in the bottom tier, it does not
mean it would have severe economic consequences, such as a recession. Instead, economic outcomes will fall
somewhere between these two extremes. Available evidence does not allow us to say exactly where each tax
option falls on this spectrum. We can, however, suggest which tax increases pose more risk to the economy than
the other options we consider. This is what our rankings are intended to communicate.
Changes Are Incremental. None of the options examined in this report, by themselves, would be a
fundamental change to the state’s tax system or economy. None will make or break the state’s economy. Instead,
they could result in incrementally more or less economic growth. None will completely change the future course of
state revenue growth, but they could make revenues grow slightly faster or slower. The incremental nature of these
options is important to keep in mind when interpreting our findings, as well as when considering the trade-offs
between tax options and changes in state spending. That being said, the situation is different if policymakers
consider combining multiple options to raise tens of billions of dollars per year. Changes of that magnitude are
considerably riskier and more unpredictable.
Terminology
Tax Base. A tax base is all activities or items that are subject to a particular tax.
Tax Rate. A tax rate typically is the percentage of the taxable activity that the taxpayer must pay in taxes.
Some taxes have a flat tax rate. This means the tax rate is the same for all taxpayers. Other taxes, like the personal
income tax, have marginal tax rates. For the personal income tax, this means that the tax rate incrementally
increases as taxable income increases. For example, the first $11,079 of a single taxpayer’s income is taxed at
1 percent. Dollars of income between $11,079 and $26,264 are taxed at 2 percent. Rates continue to step up until
you reach dollars of income over $742,953, which are taxed at 12.3 percent.
Tax Expenditure. A tax expenditure is a component of the tax system that departs from the normal
tax structure to reduce taxes for certain taxpayers, often to encourage particular behaviors or provide
targeted benefits.
Deduction. A tax deduction reduces the amount of an activity that will be subject to a tax. For example, a
personal income tax deduction reduces the income to which tax rates are applied. Personal income taxpayers
get a choice between taking a standard deduction or deducting certain itemized expenses. For example, one
deductible expense that taxpayers can itemize is their costs for charitable giving. About 30 percent of taxpayers
itemize their state deductions.
Credit. A tax credit is a dollar-for-dollar reduction in the amount of tax a taxpayer owes.

Eliminate Income Tax Exemption for Inherited Assets
This option would calculate capital gains on inherited assets based on their original purchase price. Capital
gains, which are taxed as income, are earnings from the sale of an asset. To determine a taxpayer’s capital
gain when they sell an asset, the sale price of the asset is compared to the price the taxpayer originally
paid for the asset. The rules are different, however, for inherited assets. Right now, the capital gain on an
inherited asset is determined by comparing the sale price of the asset to its value when the heir received it,
instead of the original price paid for the asset. This effectively exempts from taxation all capital gains on
the inherited asset that were earned during the life of the person passing it down. Historically, this rule
prevented inherited assets that had already been taxed once under an estate tax from being effectively
taxed again after they are sold. This rationale is no longer valid as the state no longer has an estate tax.

Modest effect on investment because the person who
invests in the asset is different from the person who

Business owners and investors will have to expand
their record keeping and will have to share more
financial information with their families. Some may

2 Percentage Point Increase in Corporation Tax Rate
This option increases the state’s tax on profits of corporations (specifically, so called “C corporations”)
from 8.84 percent to 10.84 percent. Profits are a corporation’s total earnings minus its total costs. For
corporations that operate both inside and outside of California, additional calculations must be made to
assign a share of their profits to California for taxation. This reduces the risk of a corporation being taxed
on the same profits multiple times by different states. For most corporations, the share of their profits
assigned to California is equal to the share of their national sales that occur in California. This means that a
corporation’s tax does not directly depend on how many facilities or employees they have in the state. If a
corporation moves employees or facilities out of state but keeps selling the same amount of products
here, its California taxes remain the same.

Significant share of tax cost likely shifted out of state.
Corporations likely raise prices, including on out-of-state

larger federal tax deductions. Conversely, there is some risk
some corporations exit the California market entirely.

Eliminate Certain Corporation Tax Expenditures and Increase Corporation Tax Rate
This option combines a slightly smaller tax rate increase (1.8 percentage points instead of 2 percentage
points) on corporate profits with the elimination of two corporation tax expenditures. The first tax expenditure
is related to credit unions. Credit unions are nonprofits and, therefore, their profits from providing services to
their members are not taxed. Credit unions also earn profits from activities not related to providing services to
their members—like ATM fees and investment income. Right now, these nonmember profits also are not
taxed. This option instead would tax nonmember profits. The second tax expenditure is related to cable
companies. Right now, cable companies with $250 million or more in qualifying annual operating costs in
California effectively pay a tax rate 50 percent smaller than all other corporations. This option instead would
tax cable companies at the same level as other corporations.

Eliminate Water’s Edge Election Under Corporation Tax
This option eliminates the possibility for corporations to make a “water’s edge election” when calculating
their California taxes. Corporations that operate in California and other countries can choose between two
ways of assigning a share of their profits to California. One option is to start with the worldwide profits of
the company and its related affiliates and assign a portion of those profits to California based on California’s
share of the group’s worldwide sales. Alternatively, the corporation can make a water’s edge election.
Under this option, a share of the profits of the company and its affiliates is assigned to California based on
California’s share of the sales of the U.S. portion of the group. California provides the water’s edge option
for a few reasons. Some foreign countries and corporations have expressed concern that California taxing
profits earned in other countries could result in those profits being taxed both by California and by foreign
governments, increasing the risk of double taxation. In addition, record keeping and tax preparation for
worldwide taxation is more complex. On the other hand, there are concerns that looking only at U.S.
operations provides an opportunity for corporations to hide California profits from taxation through
accounting that shifts those profits to affiliates outside the U.S.
Rankings: Eliminate Water’s Edge Election Under Corporation Tax
Budgeting
Growth
Grows about the same rate as the economy.
Stability
Prone to large year-to-year swings.
Predictability
Information about worldwide profits of many
companies is limited. Year-to-year instability
presents additional challenges.
Economy
Similar to 2 percentage point increase in corporation
tax rate, but with some additional risks. Response of
large, sophisticated corporations is hard to predict.
They may undertake new, economically unproductive
steps to reduce their California taxes. Foreign trade
partners may take actions against California.
Taxpayer Experience
Many corporations will need to implement extensive new
bookkeeping and tax administration activities.
Progressivity
With a significant share of tax costs shifted out of state, a
relatively small share of the cost would fall on ordinary
Californians.
Fairness
Offsetting fairness considerations. Current water's edge
rules may give some multinational corporations unfair
flexibility to limit their taxes compared to domestic
corporations. On the other hand, shifting to worldwide

Oil and Natural Gas Severance Tax
This option would create a new tax on the extraction of oil and natural gas in California. The tax would be
15 percent of the value of extracted oil and natural gas. This would be in addition to an existing regulatory
assessment on oil and natural gas collected by the California Department of Conservation, which currently
is $1.28 per barrel of oil or thousand cubic feet of natural gas.
Rankings: Oil and Natural Gas Severance Tax
Budgeting
Growth
Declining over time.
Stability
High dependence on oil and gas prices makes very
large year-to-year swings likely.
Predictability
Unpredictability of oil and gas markets makes this
tax very difficult to predict.
Economy
Extraction activities unlikely to change significantly.
Impact to California consumer prices likely modest, as
oil and gas are priced on a global market. Corporate
shareholders, many of whom live elsewhere, bear much
of the cost in the form of lower profits. Corporations
also would have larger federal tax deductions.
Taxpayer Experience
Existing assessment probably offers a framework to
implement severance tax without significant challenges.
Progressivity
Most costs borne by corporate shareholders who
generally are higher-income.

Extend Proposition 55
This option extends voter-approved income tax rates on high-income taxpayers. Voters approved
Proposition 30 in 2012 to temporarily increase income tax rates on high-income taxpayers. In 2016, voters
approved Proposition 55 to extend these higher rates until 2031. Prior to Proposition 30, California’s top
marginal tax rate was 9.3 percent. Proposition 30 introduced three new tax rate steps for incomes above
$361,000 ($721,000 for joint filers), with the top rate reaching 12.3 percent for income over $721,000

Split Roll Property Tax
This option, which would require voters to amend the State Constitution, taxes nonresidential property (like
commercial, industrial, and vacant properties) based on its market value instead of its original purchase
price. Local governments collect property taxes from property owners based on the value of their property.
Right now, the taxable value of all properties is based on the original purchase price. In the year a property
is purchased, its taxable value is its purchase price. Each year after that, the property’s taxable value is
adjusted for inflation by up to 2 percent. When a property is sold again, its taxable value is reset to its new
purchase price. Under these rules, the taxable value of most properties is less than their market value—that
is, what they could be sold for today. This gap is wider the longer a property has been owned. Taxing
nonresidential properties based on market value would result in owners of those properties paying more
property taxes. About 40 percent of these increased property taxes would go to schools. This would offset
state spending on schools, resulting in a commensurate increase in available state funds.
Rankings: Split Roll Property Tax

Major changes in tax processes. Increase in costs of
compliance for taxpayers. Some risk of reduced
transparency and comprehensibility for taxpayers.

Some costs shifted out of state, and property
owners tend to be somewhat higher income, but
there is still a risk that a meaningful share falls on
ordinary Californians.
Fairness
Offsetting fairness considerations. Existing favorable
treatment for longer-tenured property owners would be
eliminated. However, a new favorable treatment of
