So, you’re standing in line at the Safeway on El Camino Real, or maybe you’re eyeing a shiny new MacBook at the Stanford Shopping Center—which is technically Palo Alto, but honestly, we all treat this whole area as one big zip code. You look at the receipt. The price just jumped. That’s the Menlo Park CA sales tax hitting your wallet, and if you haven’t checked the rates lately, you might be surprised at how the math breaks down in 2026.
Right now, the combined sales tax rate in Menlo Park is 9.375%.
You’ll see some sites round that up to 9.38%, but let’s be precise. If you spend $100, you’re handing over an extra $9.38 to the government. It’s not the highest in the Bay Area—some spots in Alameda County are pushing nearly 11%—but it’s certainly high enough to make you blink twice when buying a car or a high-end bike from a local shop.
Why is the Menlo Park CA sales tax so high?
It’s easy to blame the city council, but they actually control less of this number than you’d think. California is basically a layer cake of taxes. Everyone wants a slice.
The base rate for the entire state is 7.25%. That’s the foundation. From there, San Mateo County adds its own layers. We're talking about things like Measure W, a half-cent tax for transit that voters approved a few years back to try and fix the soul-crushing traffic on Highway 101. Then there are the smaller increments for things like emergency services and library funds.

Here is how that 9.375% actually looks when you peel back the curtain:
- 6.00% goes straight to the State of California's general fund.
- 0.25% is for the San Mateo County local tax.
- 1.00% goes to the City of Menlo Park for general operations (cops, parks, fixing potholes).
- 2.125% is the "District Tax" pile, which includes San Mateo County Transit (SamTrans) and other special regional projects.
Honestly, it’s a lot of hands in one pocket. If you drive just a few miles over to a different county, that rate can shift. It's why people sometimes go "tax shopping" for big purchases, though California's "use tax" laws technically mean you owe the tax based on where you live or use the item, not just where you bought it.
What actually gets taxed (and what doesn't)
Most people think everything has tax added. Not true. California has some quirks.
If you go to a restaurant in Menlo Park, you’re paying that 9.375%. If you grab a "to-go" cold sandwich from a grocery store? Usually no tax. But if they heat that sandwich up for you? Bam. It’s now "prepared food," and the tax applies. It's a weird rule, but that’s the reality of the California tax code.
Prescription medicine and most groceries are exempt. That’s the good news. The bad news is that basically everything else—clothes, electronics, toys, and even that overpriced artisan candle you bought downtown—is fair game.
The impact of Measure CC and recent changes
While we're talking about Menlo Park CA sales tax, we have to mention the "other" taxes that hit your bill. In late 2024, Menlo Park voters looked at Measure CC. This didn't change the sales tax specifically, but it bumped the "Hotel Tax" (Transient Occupancy Tax) from 12% to 15.5%.
Why does this matter to you if you live here? Because the city uses that money to balance the budget. When the city gets more money from tourists and business travelers staying at the Rosewood or the Park James, it takes the pressure off the general fund. That means the city is less likely to come back to the voters asking for another 0.25% increase on the sales tax just to keep the library lights on.
Where does all that money go?
Menlo Park isn't exactly hurting for cash, but it’s an expensive place to run. For the 2025-2026 fiscal year, the city’s budget is hovering around $78 million.
The sales tax revenue is a huge chunk of that. It funds the 296 full-time employees who keep the city moving. It pays for the "Capital Improvement Plan," which is just fancy talk for fixing the sidewalks that the oak tree roots have destroyed. Recently, the city has been funneling more of this cash into climate resiliency projects and trying to pay down pension liabilities. It’s not glamorous, but it keeps the city from going broke ten years from now.
Surprising facts about local tax collection
Did you know that if you buy something online, Menlo Park still gets a cut? It’s called a "destination-based" tax system. Even if the warehouse is in Nevada, if the package lands on your porch in Menlo Park, the seller is supposed to charge the Menlo Park CA sales tax rate of 9.375%.

There was a time when online shopping was a tax-free Wild West. Those days are long gone. The California Department of Tax and Fee Administration (CDTFA) is very good at making sure Amazon and everyone else collects every penny.
Actionable steps for Menlo Park residents and businesses
If you're a business owner in Menlo Park, you've got to be careful. The CDTFA doesn't play around with audits. Ensure your Point of Sale (POS) system is updated to the current 9.375% rate. If you've been accidentally charging 9.25% because you haven't checked the rates in two years, you’re going to be liable for that difference out of your own pocket.
For shoppers, keep your receipts for big-ticket items. If you’re a contractor or someone who buys a lot of equipment, you might be able to find tax breaks if the items are used for specific exempt purposes (like certain manufacturing or research activities), but you'll need a tax pro to navigate that mess.
The most important thing to remember is that these rates aren't permanent. They are usually tied to specific sunset dates or "measures" that expire. Keep an eye on the November ballots. That’s where the 9.375% lives or dies. If a new transportation or school measure pops up, expect that number to tick closer to 10% before the decade is out.

To stay compliant and informed, check the California Department of Tax and Fee Administration (CDTFA) website every January and July. These are the two windows when California typically updates its district tax rates. If you are moving to the area, use a geo-based tax calculator rather than just looking at the zip code, as 94025 actually spans several different jurisdictions with slightly different local "add-ons." For most of the city proper, sticking to the 9.375% calculation will keep your books accurate and your budget on track.
