Los Angeles County’s new sales tax took effect October 1, adding 0.5 percentage point to the countywide sales-tax rate.
That means the countywide rate rises from 9.75% to 10.25%, before any additional local district taxes. The California Department of Tax and Fee Administration confirms the new rates took effect October 1. Check California’s current sales-tax rates by city or address through CDTFA.
But there’s a second part of this story that shoppers may not realize:
Residents are paying the new tax now, but Los Angeles County says it cannot spend the new revenue yet.
A lawsuit challenging Measure ER is keeping the money in an escrow account while the legal dispute moves through court.
That’s an unusual situation. So what does the new tax actually mean for your household?
First: What does the extra 0.5% cost you?
The Measure ER increase does not come out of your paycheck the way an income-tax increase would.
Instead, it adds $0.50 for every $100 in taxable purchases.
For example:
$100 in taxable spending — $0.50 extra
$500 in taxable spending — $2.50 extra
$1,000 in taxable spending — $5 extra
$5,000 in taxable spending — $25 extra
$10,000 in taxable spending — $50 extra
Those are illustrations, not estimates of what any household will actually pay. Your annual cost depends on how much you spend on items that are subject to sales tax.
That’s an important financial contrast: the tax is tied to taxable spending, not your income.
For a household that averages $2,000 a month in taxable purchases, the additional tax would be about $10 a month, or $120 a year. At $4,000 in taxable purchases per month, it would be about $240 a year.
The actual total can vary because not every purchase is taxable.

Your city may have a higher rate
The countywide increase is only one part of the sales-tax calculation. Cities and special tax districts can add their own rates.
As of October 1, CDTFA lists these combined rates in several L.A. County cities:
Los Angeles — 10.25%
Pomona — 11.00%
Alhambra — 11.00%
El Monte — 11.00%
Montebello — 11.00%
San Gabriel — 11.00%
Pico Rivera — 11.25%
Covina — 11.25%
Compton — 11.25%
There are more local variations across the county, so the safest way to check your rate is CDTFA’s address-based lookup rather than assuming every city has the same total.
Here’s the twist: You pay it, but the County can’t spend it yet
Voters approved Measure ER in June by 50.64% to 49.36%, according to the official Los Angeles County election results. The ballot described it as a five-year, 0.5% general sales tax intended to help address severe funding pressures and protect essential services, including health care.
Then the legal challenge changed the immediate picture.
The Libertarian Party of Los Angeles County filed a lawsuit challenging the constitutionality of Assembly Bill 1768, the state law that allowed the County to exceed the otherwise applicable local sales-tax limit. The County disputes that challenge.
Under the legal framework described by the County, the new tax still takes effect, but the revenue must remain in an escrow account while the lawsuit is pending.
So, for now:
The tax is being collected.
The County cannot spend the new revenue.
The money must remain in escrow until the legal dispute is resolved.
The County says that if the tax is ultimately ruled invalid, the state would administer refunds.
What was the money supposed to support?
Measure ER is a general sales tax. The County said the new revenue was intended to help address pressure on health care, public health and human services, including financial problems connected to reductions in state and federal funding.
That matters because the County is already dealing with major budget pressures. Parriva recently broke down the County’s new $54.2 billion budget and the competing demands facing health care, homelessness, wildfire recovery and other services.
The new sales-tax revenue is separate from that overall budget, but it is part of the County’s broader effort to protect services as other funding sources come under pressure.
What should residents watch now?
For shoppers, the immediate change is straightforward:
Your local sales-tax rate is higher starting October 1.
For the County, the situation is more complicated.
The court case will determine whether and when the new revenue can be distributed and spent. Until then, residents continue paying the tax while the money sits in escrow.
That creates an unusual accountability question for the months ahead:
How much money is being collected, where is it being held, and what happens to it depending on the outcome of the lawsuit?
For households, the most useful number is not simply the headline 10.25% countywide rate.
It’s how much taxable spending passes through your household.
An extra 50 cents on $100 may sound small. Across hundreds or thousands of dollars in taxable purchases over the year, it becomes a real household expense.
And that is why understanding the rate and following where the money goes is key.
