Prop 42: Personal property taxes

Prohibits New State Personal Property Taxes and Certain Retroactive State Taxes

Initiative Constitutional Amendment. A change to the California Constitution that voters put on the ballot by signing petitions.

In plain English

Proposition 42 would amend the state Constitution. It would bar new state taxes on owning personal property. Personal property is everything people own except real estate. This includes financial assets like stocks and retirement accounts, which are not taxed for ownership now. The measure would also limit new state taxes that apply retroactively, meaning to things that happened in the past. It would apply to new taxes enacted or taking effect on or after January 1, 2026. Taxes enacted after January 1, 2026 that conflict with it would be nullified. It could reduce future tax revenue, but when and by how much is unclear. If it gets more yes votes than Proposition 40, courts could stop Proposition 40 from becoming law.

A YES VOTE MEANS

The state could not establish new taxes on the ownership of financial assets or other personal property.

A NO VOTE MEANS

The state would continue to have the option to establish new taxes on the ownership of financial assets or other personal property.

YES ON PROP. 42: PROTECT YOUR RETIREMENT AND LIFE SAVINGS FROM STATE TAXES

California is now the third most expensive state to retire in the nation. Every year, higher costs and taxes make it harder to save. An April 2026 survey found 73% of Californians know someone who has had to delay retirement for financial reasons.

CALIFORNIA CONSTITUTION CURRENTLY ALLOWS DOUBLE TAXATION

Yet, California's Constitution currently allows the Legislature to tax the value of our personal property like retirement funds and savings accounts, even though residents already pay income tax on that money when they earn it. This means politicians can tax the same money twice: once when you earn it, and again when it is sitting in your retirement funds or savings accounts. That's double taxation!

In the last few years alone, the Legislature and special interests have introduced six separate proposals that would tax retirement and savings accounts.

Taxes and cost of living are already too high in California - we need protections against taxes on our personal property and retirement savings.

PROP. 42 PROHIBITS TAXES ON RETIREMENT AND SAVINGS

Prop. 42 amends the state Constitution to protect Californians from this double taxation by special interests and politicians. Specifically, the measure:

• Prohibits new taxes on personal property, such as retirement funds, pensions and savings accounts; • Prohibits retroactive taxes; and • Prohibits all new taxes on retirement and savings this year and in the future.

PROP. 42 PROTECTS ALL FORMS OF RETIREMENT FUNDS AND SAVINGS FROM NEW TAXES

Roughly 80% of Californians report having some form of retirement fund or savings, including young workers just beginning to save; teachers, firefighters and police officers with pensions; and retirees who depend on their savings for financial security.

This measure protects all forms of personal property from new taxes, including 401ks, pensions, IRAs and personal savings.

"Prop. 42 protects Californians' savings and retirement. Whether it's a union member's hard-earned pension or a small business owner's IRA, new taxes on retirement shouldn't stand between people and the security they've planned for." - Chris Hannan, President, State Building and Construction Trades Council of California representing hundreds of thousands of union construction trades workers.

PROP. 42 PROHIBITS UNFAIR RETROACTIVE TAXES

The state should not be able to pass new taxes that apply retroactively to money that taxpayers earned in the past. Prop. 42 requires any new taxes to apply only after voters have approved them.

"It's a question of fairness and common sense. People plan their retirement for years - they deserve stable, predictable rules that don't change after years of saving and planning. Prop. 42 provides that certainty." - Sean Morgan, licensed financial advisor

Prop. 42 is supported by a broad coalition of seniors, veterans, small business owners, blue-collar workers, retirees, including groups like the California Professional Firefighters and Disabled American Veterans, Dept. of California.

Californians are already struggling with high costs of living and high taxes. Many work their entire lives to achieve some measure of retirement security. It should be illegal for politicians and special interests to tax our retirement and savings.

You earned and saved it. Now we need to protect it. Please join us in voting Yes on 42. YesonProp42.org

THIS IS ANOTHER BILLIONAIRE-FUNDED TRICK

Don't be fooled - Prop. 42 is not really about protecting your retirement savings from new taxes.

It's a redundant, expensive trick to allow approximately 200 billionaires to keep avoiding paying their own taxes while YOU get stuck with the bill.

PROP. 42 WOULD CANCEL OUT THE BILLIONAIRE TAX

Prop. 42 is a billionaire-funded scheme designed specifically to undo the California Billionaire Tax, Prop. 40.

Prop. 42 was put on the ballot because billionaires don't want to pay their fair share. They'd rather millions of working people lose healthcare than pay a modest, one-time tax on their extreme wealth.

WHO'S BEHIND THIS? SOME OF DONALD TRUMP'S DONORS

The billionaires behind this don't care about protecting your retirement savings. They're protecting themselves. They've been getting out of paying their own taxes for years through loopholes and tax breaks.

This sham initiative was created to trick voters like you into making a billionaire tax impossible to enforce. That's why you must vote NO.

PROP. 40 WOULD ONLY TAX BILLIONAIRES' $2 TRILLION IN WEALTH

The billionaires behind Prop. 42 have spread lies about the California Billionaire Tax (Prop. 40), trying to trick voters into thinking that their retirement and savings are at risk.

Don't buy the fear-mongering. The California Billionaires Tax ONLY applies to billionaires. It's about making billionaires finally pay their fair share so we're not stuck with shuttered hospitals and skyrocketing healthcare costs.

Vote NO on Prop. 42.

VOTE NO ON PROP. 42. This is a billionaire-funded initiative designed specifically to undo the California Billionaire Tax, Prop. 40.

PROP. 42 WOULD CANCEL OUT THE BILLIONAIRE TAX

Prop. 42 was put on the ballot for one reason - because billionaires don't want to pay their fair share. This initiative was created to trick voters like you into making a billionaire tax impossible to enforce. That's why you must vote NO.

Don't fall for the billionaires' lies. Prop. 42 isn't about preventing new taxes on personal property. It's about preventing one specific tax that billionaires want to avoid, because they'd rather millions of working people lose healthcare than pay a modest, one-time tax on their extreme wealth.

PROP. 42 WAS FUNDED BY BILLIONAIRES WHO WANT YOU TO PAY MORE FOR HEALTHCARE

One of Prop. 42's main funders is Google founder and Trump donor Sergey Brin, whose wealth has DOUBLED to nearly $300 billion since Trump's election. Now he's spent over $57 million to fund sham measures like Prop. 42 that attempt to cancel out a billionaire tax. U.S. Senator Bernie Sanders called this arrogant move by Brin "unacceptable."

Donald Trump took money out of working peoples' pockets and gave it to billionaires like Brin through massive tax breaks. Now, the billionaires backing Prop. 42 want YOU to pay more for your healthcare.

VOTE NO ON PROP. 42 IF YOU SUPPORT THE BILLIONAIRE TAX

We have a chance to make billionaires pay their fair share to keep hospitals open and healthcare affordable for California's working families. Vote NO on Prop. 42.

WHO SUPPORTS PROP. 42

Prop. 42 is supported by hundreds of thousands of seniors, veterans, firefighters, blue-collar workers, public-safety officers and working families because it protects the retirement and savings of ALL Californians from new taxes. Who opposes 42? One organization that wants to tax retirement accounts.

WHY WE NEED PROP. 42

Sacramento politicians and special interests have repeatedly tried to pass taxes on retirement and personal savings accounts in recent years. They've relied on a loophole in California's Constitution that allows government to tax our income when we earn it, and AGAIN when it is simply sitting in our savings and retirement accounts.

CALIFORNIA IS EXPENSIVE ENOUGH WITHOUT DOUBLE TAXATION

Prop. 42 prohibits this double taxation by PROHIBITING ALL NEW TAXES ON RETIREMENT AND SAVINGS ACCOUNTS and other personal property, whether proposed by legislation or ballot measure, including proposals on this year's ballot and in the future.

It is a comprehensive constitutional protection against politicians or special interests trying to tax our retirement funds and savings accounts.

WHO BENEFITS FROM PROP. 42

Prop. 42 protects the retirement and savings for all Californians - young workers just beginning to save; teachers, firefighters and police officers with pensions; retirees and veterans who depend on their savings for financial security.

You saved it. You deserve to keep it.

Prop. 42 asks a simple question: should California politicians have the power to tax your personal property, including retirement and savings accounts?

If you think your retirement and savings should be protected from taxes, vote Yes on 42.
