Property taxes and city fees in Palo Alto

Taxes in Palo Alto come from several directions. Santa Clara County values property and collects the property tax. Voters in the city, the school district and other agencies add special taxes on top. The city itself charges a utility users tax on monthly utility and phone bills, plus a long list of service fees. None of it is complicated once you know who does what, but the deadlines are strict and penalties are steep.

This guide explains the basics as the county and city publish them. It is general information, not tax advice. For your own situation, talk to a tax professional or call the agencies listed below.

Who does what

Two county offices handle property tax. Mixing them up wastes time.

The County Controller calculates the bill amounts and the Clerk of the Board handles formal assessment appeals. If you think your value is wrong, start with the Assessor. If you have a question about a bill or a payment, call Tax and Collections.

How property tax is calculated

California property tax rests on Proposition 13, which voters approved in 1978. According to the county's property tax FAQ, the general levy is limited to 1 percent of assessed value. Your bill also includes voter-approved special taxes and any city or district direct assessments.

The assessed value is usually set when you buy, based on the purchase price. After that, the Assessor says it can rise by no more than 2 percent a year for inflation, no matter how fast the market moves. Reassessment at market value happens only when the property changes ownership or has new construction. That is why two similar houses on the same Palo Alto street can carry very different tax bills. Our real estate guide explains what this means for buyers.

Supplemental bills

Buyers often get a surprise bill in their first year. When property changes hands or new construction is finished, the county issues a supplemental tax bill. It covers the difference between the new and old values for the months left in the fiscal year, multiplied by the tax rate. The county stresses that lenders do not receive copies of supplemental bills, even if your lender pays your regular taxes from an escrow account. Pay it yourself or forward it to your lender. Supplemental bills have their own due dates, which depend on when they are mailed.

Due dates and penalties

The regular annual bill is split into two installments:

If a delinquent date falls on a weekend or county holiday, it moves to the next business day. December 10, 2026 is a Thursday. April 10, 2027 is a Saturday, so under the county's rule that deadline moves to the next business day. Confirm the date on your bill.

A late installment gets a 10 percent penalty plus a $20 cost. Mailed payments must carry a U.S. Postal Service postmark on or before the delinquent date. The county accepts only USPS postmarks. Not receiving a bill does not excuse a penalty. If yours has not arrived, call (408) 808-7900 for a duplicate.

Paying

The county takes online payments at payments.sccgov.org/propertytax by electronic check or card. It says eCheck payments carry no extra charge, while card payments add a processing fee. You can also mail a check or use the 24-hour drop box at 110 W. Tasman Drive in San José. If you are not sure whether your lender pays your taxes, the county says to ask the lender and, when in doubt, pay yourself. It does not excuse penalties caused by a misunderstanding with a lender.

Exemptions, reviews and appeals

• Homeowners' exemption. If you own and live in your home, you can get up to $7,000 taken off its assessed value. The Assessor's regular filing deadline is February 15. Later claims receive a reduced amount.
• Decline in value. If the market value of your property falls below its assessed value, you can ask the Assessor for a review using a one-page form. Requests are due by August 1 of the current assessment year.
• Formal appeals. Regular assessment appeals are filed with the Clerk of the Board between July 2 and September 15 each year. Keep paying your bill while an appeal is pending.
• Family transfers. Proposition 19, passed in 2020, changed the rules for transfers between parents and children and for some older homeowners who move. The Assessor publishes a separate guide.

Mailing address changes for tax bills go through the Assessor, not Tax and Collections.

Parcel taxes and direct charges

Beyond the 1 percent levy, a Palo Alto bill carries a set of other lines. Voter-approved bonds add a percentage on top of the base rate. Parcel taxes are usually flat amounts per parcel rather than a percentage of value. School districts, community colleges and special districts often use them. Each must be approved by voters. Direct assessments pay for specific services, such as flood control or other district programs.

Each line names the agency that charges it. If you have a question about a parcel tax or direct charge, contact that agency rather than the Assessor. Some school parcel taxes offer exemptions, for example for older homeowners, but each agency sets its own rules and application process. Taken together, these extra charges are why Palo Alto bills usually come to somewhat more than 1 percent of assessed value. Ballot measures that add or renew these taxes appear on local ballots, which our voting and elections guide explains.

The utility users tax

Palo Alto's utility users tax shows up every month. The municipal code sets it at 5 percent of charges for electricity, gas and water. A separate rate applies to telephone service, including mobile phones. Measure C, which voters approved in November 2014, lowered that rate from 5 percent to 4.75 percent and applied it equally regardless of technology. All proceeds go to the city's general fund, which pays for services such as police, fire, parks and libraries.

For city utilities, the tax is calculated on your City of Palo Alto Utilities bill. When the city proposes utility rate increases, it shows the tax in the totals. Our utilities guide explains the bill. For phones, your carrier collects the tax and sends it to the city. See our internet and cell service guide for more on phone bills.

City fees residents meet

Palo Alto pays for many services through fees rather than taxes. These come up most often:

• Refuse. Garbage service is billed on the city utility bill and priced by the size of your black cart. Our trash and recycling guide lists the rates.
• Stormwater. A stormwater management fee also appears on the utility bill. The city says it rises with the consumer price index under a 2017 ballot measure.
• Parking permits. Residential permit districts charge for permits, as our parking permits guide explains.
• Dog licenses. Licenses go through the Police Department's Animal Control Division. See our pets guide.
• Building permits. Fees depend on the project. Our building permits guide covers the process.

The business registry fee

Businesses with a fixed place of business in Palo Alto, such as an office or storefront, must hold a business registry certificate. New businesses register within 30 days of starting. Certificates expire on March 31 each year. When we checked, the city listed an annual payment of $54, which includes a $4 state fee for disability access programs, with late fees for payments received after April 30. The city lists several exemptions, including some home-based businesses. Palo Alto also has a business tax based on square footage. The city's business registry and tax page and our business registration guide have the details.
