In the 95050 ZIP code covering most of Santa Clara, the combined sales and use tax rate is 9.125%, and the base property tax rate is 1% of assessed value. Most property owners actually pay somewhere between 1.2% and 1.4% once voter-approved bonds and special assessments land on the bill. Both figures sit above national averages and reflect the layered state, county, and district taxes that fund services across Silicon Valley.
How the 9.125% Sales Tax Breaks Down
The 9.125% rate stacks California’s 7.25% statewide minimum with district taxes approved by Santa Clara County voters.1California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rate Information Retailers collect the full amount at checkout and remit it to the California Department of Tax and Fee Administration.2California Department of Tax and Fee Administration. Sales and Use Tax in California
Within the 7.25% state portion, 1% flows directly to the city and county under the Bradley-Burns Uniform Local Sales and Use Tax Law set by Revenue and Taxation Code section 7203.1.3California Department of Tax and Fee Administration. Uniform Local Sales and Use Tax Regulations – Article 19 That slice funds general city and county operations. The rest of the state portion goes to the general fund, education, and other state programs.
The remainder above 7.25% comes from voter-approved district taxes, most of which support the Santa Clara Valley Transportation Authority:
- 2000 Measure A: a half-cent sales tax for transit improvements, collecting through March 2036.4Santa Clara Valley Transportation Authority. 2000 Measure A
- 2016 Measure B: a half-cent sales tax for transit, highways, expressways, and bicycle and pedestrian projects, collecting through March 2047.5Santa Clara Valley Transportation Authority. About 2016 Measure B
Smaller district levies fill the gap between those two measures and the full 9.125% rate. Because voters can approve new measures and old ones expire, the combined rate shifts over time.

What the Sales Tax Applies To
The 9.125% applies to most tangible retail goods: electronics, furniture, household items, and clothing. California taxes clothing at the full rate with no apparel exemption.
Groceries bought for home preparation are exempt, as are prescription medications and certain medical devices.7California Tax Service Center. What Is Taxable Hot prepared food sold for immediate consumption is taxable, which creates some odd lines inside a single supermarket. A rotisserie chicken from the deli counter is taxed; a raw chicken from the meat case is not.
Property Tax: The 1% Base and the Prop 13 Cap
Property owners pay an ad valorem tax based on assessed value. Under Article XIII A of the California Constitution, known as Proposition 13, the base rate cannot exceed 1% of the property’s full cash value.8California Legislative Information. California Constitution Article XIII A – Tax Limitation Full cash value generally equals the purchase price at the most recent sale or the value assigned after new construction.
After that initial assessment, the assessed value can rise by no more than 2% per year, no matter what the market does. A home bought for $1,000,000 might be assessed at $1,020,000 the next year even if comparable homes nearby sell for $1,200,000. This cap is why long-time homeowners in Santa Clara often pay far less than recent buyers of similar properties.
The Santa Clara County Assessor’s Office handles valuations. When ownership changes or new construction is completed, the assessor reappraises the property and sets a new base year value, resetting the 2% annual cap from that figure.9County of Santa Clara. About the Office
What Pushes Your Bill Above 1%
The 1% base is just the starting point. Most 95050 property tax bills end up between 1.2% and 1.4% of assessed value once voter-approved bond debt and special assessments are added. Each charge appears as its own line on the annual bill from the Santa Clara County Department of Tax and Collections.
Voter-approved bonds fund long-term capital projects for school districts, community college districts, and other local agencies. When a district passes a bond measure, property owners within its boundaries repay the borrowed funds through a small percentage added to their bills over the bond’s life. Which bonds appear on your bill depends on which taxing districts your parcel falls within.
Special assessments often work as flat-dollar charges rather than percentages. The Santa Clara Valley Water District levies a parcel tax for flood protection and water supply. Some parcels also carry landscape and lighting district assessments or other localized fees.10Santa Clara County Department of Tax and Collections. City and Special District Parcel Tax Exemptions
Mello-Roos Districts
Some parcels in and around 95050 sit within a Community Facilities District, commonly called Mello-Roos. Created under the Mello-Roos Community Facilities Act of 1982, these districts let local governments and developers levy a special tax on parcels in a defined area to finance public infrastructure such as schools, roads, parks, and fire stations.11Justia Law. California Government Code Title 5 Division 2 Part 1 Chapter 2.5 – The Mello-Roos Community Facilities Act of 1982
Mello-Roos charges show up as a separate line under “special taxes” or “community facilities district.” They can add hundreds or thousands of dollars per year, especially in newer developments where infrastructure was financed through the district rather than paid upfront by the developer. If you’re buying in 95050, check the property tax bill carefully for CFD charges before closing. Sellers are required to provide a Mello-Roos disclosure when a property falls within one of these districts.
Payment Deadlines and Penalties
Santa Clara County mails secured property tax bills in the fall. Payment splits into two installments:12California Tax Service Center. Property Tax Function Important Dates
- First installment: due November 1, delinquent after December 10.
- Second installment: due February 1, delinquent after April 10.
Miss either deadline and a 10% penalty hits the unpaid amount. The second installment also carries an additional administrative fee. There is no grace period, and the county does not send reminder notices before the delinquency date. If both installments remain unpaid through June 30, the property becomes tax-defaulted and begins accruing additional monthly interest.
Supplemental Bills After You Buy
New buyers in 95050 often get caught off guard by a supplemental tax bill. When you purchase, the assessor recalculates value based on the sale price and issues a separate bill for the difference between the old assessed value and the new one, prorated for the months remaining in the fiscal year.13County of Santa Clara. Frequently Asked Questions for Property Taxes
Most supplemental bills arrive within nine months of closing. If the sale substantially raised the assessed value, the supplemental bill can be large. Buying a home previously assessed at $600,000 for $1,500,000 in October means the supplemental tax covers the $900,000 difference at the applicable rate, prorated through June 30. Supplemental bills split into two installments, each with its own delinquency date.
Documentary Transfer Tax at Sale
When real property in 95050 changes hands, a documentary transfer tax is paid at recording. In Santa Clara County the rate is $1.10 per $1,000 of property value.14County of Santa Clara. Recording Real Estate On a $1,500,000 home, that works out to $1,650.
The city of Santa Clara does not add a city-level transfer tax, unlike nearby San Jose, Palo Alto, and Mountain View, where the combined rate reaches $3.30 per $1,000. Certain transfers are exempt, including transfers between spouses, transfers into revocable trusts, and some transfers tied to divorce or inheritance. Any claimed exemption must be documented on the deed with a valid legal basis.14County of Santa Clara. Recording Real Estate
