How San Mateo County Property Taxes Are Assessed
In San Mateo County, property taxes are determined based on the assessed value of your real estate, as calculated by the County Assessor’s Office. Each year, the Assessor reviews property data, including sales, renovations, and market trends, to establish a taxable value – commonly known as the assessed value. This figure is typically based on either the purchase price (adjusted annually by a limited inflation factor under California’s Proposition 13) or a revised fair market value after certain events like a sale, new construction, or a decline in market conditions.
Your property tax bill is then calculated by applying the county’s standard tax rate – usually around 1% – to your assessed value and any voter-approved special assessments. But what happens when your assessed value is too high? Many homeowners and commercial property owners find themselves overpaying each year due to inaccurate valuations, especially after market fluctuations or structural issues not considered in the assessment.
Understanding how these assessments work is the first step in identifying whether you may be eligible for a reduction and potentially save thousands in annual property taxes.
The Value Of Appealing Your San Mateo County Property Tax
Filing a property tax appeal in San Mateo County can be a powerful way to take control of your finances and ensure you’re only paying your fair share. Property assessments aren’t always accurate, especially in a volatile real estate market where property values can shift from year to year. An overvaluation could mean paying hundreds or even thousands more than necessary in property taxes.
Appealing your assessment opens the door to a possible tax reduction based on fair market value. This isn’t just about lowering your annual expenses and protecting your investment. If your property’s assessed value is inflated, it can affect your net income, resale value considerations, and long-term budgeting.
An appeal isn’t a confrontation – it’s a legal right. And with the proper support, the process doesn’t have to be complicated. Appealing could result in significant savings without disrupting your day-to-day life. Whether you own a home, a rental, or a commercial property, it’s worth reviewing your assessment to see if a correction is due.

Frequently Asked Questions About San Mateo County Property Tax Appeal
What is the deadline to file a property tax appeal in San Mateo County?
The official filing period for property tax appeals in San Mateo County typically runs from July 2 to September 15 each year. This timeframe applies to most real property owners who wish to challenge the assessed value on their annual property tax bill. If you miss this window, you’ll generally have to wait until the next tax year to file.
Can I appeal my property taxes every year?
Yes. Property owners in San Mateo County can file an appeal annually during the designated filing period, especially if market conditions or property changes warrant a reevaluation. It’s a strategic way to align your tax obligations with current values.
What documents or evidence do I need to support my appeal?
Supporting documents may include comparable property sales, recent appraisals, photos showing condition issues, or records of changes in use or income (for commercial properties). These materials help demonstrate that your property’s assessed value does not reflect its fair market value.
Is there a fee to file an appeal with the county?
No, San Mateo County does not charge a filing fee to submit a formal assessment appeal. However, any professional services you engage in (such as representation by a tax appeal expert) may involve separate fees – unless you choose a contingency-based provider like Icon.
How long does the appeal process take in San Mateo County?
The process can vary but generally takes several months from the filing date. After submission, your case may be scheduled for a hearing before the county’s Assessment Appeals Board, where a final decision will be made.
Can commercial properties also be appealed in San Mateo County?
Absolutely. Both residential and commercial property owners have the right to file an appeal. Commercial cases may involve more complex valuation methods, but the potential savings are often higher.
What if my appeal is denied? Can I appeal again?
If your appeal is denied, you can typically refile the following year during the next open filing period. Additionally, depending on the circumstances, you may explore further review options, such as requesting a reconsideration or appealing to the Superior Court.
Does an appeal affect my ability to sell my property?
No. Filing a property tax appeal does not impact your ability to sell, refinance, or lease your property. A successful appeal may make your property attractive to buyers by reducing future tax burdens.
Will appealing my property taxes trigger a reassessment?
Not necessarily. When you appeal, the focus is on proving that the current assessed value is too high. If the county disagrees, the value typically remains unchanged. However, in rare cases with inaccurate data, an appeal could lead to a minor adjustment either way.
Can I track the status of my property tax appeal online?
San Mateo County’s Assessor’s Office provides limited online tools to track your appeal status. However, if you’re working with a professional like Icon, they will handle updates and communication on your behalf, giving you peace of mind throughout the process.
