California Considers Doubling its Taxes

California Considers Doubling its Taxes

Editor’s Note: The California Policy Center has earmarked ACA 11 as a high impact bill in 2022. The following analysis of ACA 11 was conducted and first posted at the Tax Foundation. The California Policy Center encourages our readers to visit our “Take Action” portal to contact your legislator without leaving this site. 

proposed constitutional amendment (ACA 11) in California would increase taxes by $12,250 per household, roughly doubling the state’s already high tax collections, to fund a first-in-the-nation single-payer health-care system. The top marginal rate on wage income would soar to 18.05 percent—nationally, the median top marginal rate is 5.3 percent—and the state would adopt a new 2.3 percent gross receipts tax (GRT), at a rate more than three times that of the country’s highest current pure GRT.

All told, the new tax package is intended to raise an additional $163 billion per year, which is more than California raised in total tax revenue any year prior to the pandemic.

The new taxes would take three forms:

  1. Surtaxes atop the current individual income tax structure beginning at $149,509 in income;
  2. A graduated-rate payroll tax system with the top rate kicking in for employees with more than $49,990 in annual income; and
  3. A gross receipts tax of 2.3 percent, excluding the first $2 million of business income.

Two states currently have payroll taxes for purposes other than funding their unemployment insurance system. In Massachusetts, a recently adopted payroll tax of 0.68 percent is imposed atop the state’s 5.0 percent flat individual income tax. In Nevada, there is a payroll tax of 1.475 percent in lieu of any individual income tax. California would impose a payroll tax of up to 2.25 percent atop an individual income tax that already has a top marginal rate of 13.3 percent.

Similarly, several states have gross receipts taxes in lieu of corporate income taxes. In Ohio, for instance, there is a 0.26 percent gross receipts tax, adopted to replace the state’s corporate income tax, capital stock tax, and business tangible property tax. In California, by contrast, a 2.3 percent gross receipts tax—almost nine times Ohio’s rate—would be imposed in addition to tangible property taxes and an 8.84 percent corporate income tax, and an aggressive one at that, the only state-level corporate income tax in the country with a worldwide tax base.

And while 16 states either implemented or enacted individual or corporate income tax cuts in 2021, and more are looking to join them in 2022, California policymakers want voters to approve five new surtaxes, with a top rate of 2.5 percent atop the current 13.3 percent top marginal income tax rate and the proposed new 2.25 percent payroll tax, for a combined top marginal rate of 18.05 percent. This is more than 7 percentage points higher than the next-highest rates in Hawaii (11 percent), New York (10.9 percent), and New Jersey and the District of Columbia (both at 10.75 percent).

Issues with the proposal abound.

For instance, the payroll tax exempts employers with fewer than 50 resident employees, punishing small businesses for expanding and creating a meaningful tax cliff. Imagine, for instance, the overly simplified hypothetical of a company with 49 employees making $80,000 each. At 49 employees, the company has no payroll tax burden. Hiring one additional employee generates a tax bill of $90,000—more than that employee’s salary!

Gross receipts taxes are widely understood as extremely disruptive and inequitable taxes, because they are imposed on businesses without regard to their profit margins. For low-margin businesses like supermarkets, 2.3 percent of gross receipts may literally exceed current profits even if the company is doing well. For instance, Kroger’s profit margins dipped to 0.75 percent in late 2021 and have historically hovered around 1.75 percent. These taxes are even worse for businesses posting losses, including startups that haven’t turned profitable yet, because they are taxed on their receipts even if their expenditures exceed revenues. For startups, a high-rate gross receipts tax could be disastrous.

The surtax, meanwhile, with additional rates of 0.5 percent to 2.5 percent atop the current income tax, does not take married filers into account. So while California’s state income tax avoids a marriage penalty for most filers by doubling bracket widths (there is already an additional 1 percent above $1 million which is not adjusted), the new surtaxes do not. The $149,509 kick-in of the 0.5 percent surtax applies to individual or household income equally.

Similarly, these surtaxes do not align with current brackets, so they yield a highly convoluted tax system. Add the payroll tax—which is borne economically by taxpayers even if remitted by their employers—and it is essentially 18 brackets, as follows. Taxpayers earning less than $50,000 would face (inclusive of the new payroll tax) double-digit marginal tax rates.

These taxes, moreover, could be increased by simple majorities in the legislature, as the bill exempts the three new taxes from the constitution’s supermajority requirements for tax increases. If a future legislature decides that doubling the state’s tax collections was insufficient, the constitution’s supermajority requirement would not stand in its way. And while the new surtaxes are inflation-indexed (the payroll tax’s second bracket is not), the legislature is authorized to suspend inflation indexing at any time, which would lead to the particularly curious case of inflation-indexing the standard income tax brackets but not the surtax brackets.

This is not the first time California lawmakers have considered creating a single-payer health system, which previous estimates pegged as requiring $200 billion in additional state funding. This assumes, moreover, that California secures federal approval to redirect approximately $200 billion in federal funding toward a health-care match, since the full cost of the program is about $400 billion per year. Even with that match, the numbers only balance if a single-payer system generates significant cost savings, an assumption that is, at minimum, controversial. And as with prior considerations of one-state single-payer proposals, there are questions of whether residents would still need health insurance to cover them while outside the state, depending on how the program is designed.

The proposal for a $163 billion a year tax increase comes at a time when the California Legislative Analyst’s Office is projecting a $31 billion surplus, after tax collections grew at an annual rate of 30 percent, the fastest in at least four decades. The $163 billion in additional revenue that proponents of ACA 11 hope to generate each year exceeds all state revenue for any year prior to FY 2020.

Like most states, California’s revenues grew rapidly over the past two years. Unlike most states, however, California faces a downside risk in the form of a continuing exodus of taxpayers, accelerated by the rise of remote work and increased workplace mobility. California lost 0.8 percent of its population between April 2020 and July 2021, the fourth-largest decline in the country after the District of Columbia, New York, and Illinois.

Practically doubling state taxes—even if the burden is partially offset through state-provided health coverage—could send taxpayers racing for the exits.
