Assessor
The Santa Clara County Assessor maintains property assessment information for homes, land, and business property. This article explains which Assessor service to use for a property search or valuation question, how homeowners and businesses can handle common filings, what to do if an assessed value appears too high, and which office handles matters outside the Assessor’s work.
What the Assessor Handles
The Santa Clara County Office of the Assessor is the starting point for questions about assessed property values, ownership information maintained for assessment purposes, exemptions, changes in ownership, parcel identification, and business personal property assessments. Its Real Property Division handles general real property valuation questions. Other units handle exemptions, property transfers, mapping and parcel number issues, and business property.
An assessed value is connected to a property tax bill, but the Assessor does not handle every question that appears on that bill. The Tax Collector handles property tax billing questions. The Recorder handles recorded documents, while the Assessor’s Public Service staff can assist with verification of ownership information. If your question concerns the amount due or payment of a bill, direct it to the Tax Collector. If you need a recorded document, direct the request to the Recorder.
Before contacting an office, identify the issue as precisely as you can. A question about the Assessor’s valuation belongs with the Assessor’s Real Property Division. A mailing address change belongs with the Assessor’s Address Changes staff. A parcel number change, property split, or legal description issue belongs with the Mapping & Title I.D. Unit. The Assessor’s Office phone directory identifies these units and their areas of responsibility.
Property Search and Assessment Look-Up
The Assessor provides a real property search for people seeking Assessor property information. The Assessor’s homepage also provides shortcuts to Property Search and Assessment Look-Up. Select the service that matches the record you need rather than treating a property search, an assessed value notice, and a tax bill as interchangeable documents.
If you are reviewing the value reported to a property owner, the Assessor has a separate Notification of Assessed Value look-up. Santa Clara County mails a Notification of Assessed Value postcard to property owners at the end of June. It indicates the property’s taxable value. Keep the assessment year in mind when comparing a notice with other records; a value dispute depends on the value for the relevant assessment year and the January 1 lien date.
Have the property address and assessor’s parcel number available when you contact the Assessor about a specific property. The Assessor expressly asks homeowners to provide both when requesting a Homeowners’ Exemption claim form. Those identifiers also help staff understand which property your question concerns, especially if you are asking about a value notice, ownership information, or a parcel number change. Do not place a home address, tax ID, Social Security number, or other personal information in the website’s general page-feedback form.
When a Search Raises Questions
A property record may lead to different questions. The Real Property Division handles appraisal and general valuation questions. The Property Transfer Unit handles changes of ownership, determinations of reappraisability, and exclusions from reassessment. The Mapping & Title I.D. Unit handles mapping questions, parcel number changes, property splits or combinations, situs changes, and legal property description issues. Routing the question to the relevant unit can save a second referral.
The Assessor’s Public Service staff handles verification of ownership information and provides ownership information through materials such as individual parcel maps and computer printouts. For a question about a recorded deed or other recorded document itself, the Recorder is the appropriate office. An Assessor search should not be mistaken for a request for a recorded document.
Homeowners’ Exemption
The Homeowners’ Exemption can reduce a qualifying dwelling’s assessed value by up to $7,000. The Assessor describes the resulting property tax savings as approximately $70 to $80 a year. To qualify, you must be an owner, co-owner, or purchaser named in a contract of sale, and you must occupy the home as your principal place of residence at 12:01 a.m. on January 1 of each year.
A rented property, a vacant and unoccupied dwelling, or a vacation or secondary home does not qualify under the Assessor’s stated rules. You may have only one Homeowners’ Exemption at a time in California. The Assessor describes a principal residence in terms of where you return at the end of the day, register your vehicle and to vote, and receive mail. Review those facts before filing rather than assuming that ownership alone is enough.
Filing Dates and Later Changes
For the year in which you occupy the dwelling on the January 1 lien date, the full exemption is available if you file by 5:00 p.m. on the following February 15. A claim filed from the following February 16 through 5:00 p.m. on December 10 receives 80% of the exemption. The Assessor’s exemption page offers an online submission option. You may also request a claim form from the Exemptions Unit; provide the property address and assessor’s parcel number when doing so.
The exemption generally remains in effect after it is granted while the claimant continues to qualify. You must notify the Assessor when the property is no longer your principal residence. Recording a deed, including a transfer into or out of a trust or a change in co-owners’ names, automatically terminates the exemption for the upcoming fiscal year. The Assessor says a new claim is automatically sent to the new owner of record. Check the exemption status after a deed change instead of assuming an earlier claim continues.
A Homeowners’ Exemption may also apply to a supplemental assessment. The Assessor states that the claimant must occupy the home as a principal residence within 90 days after the change of ownership or completion of new construction, and must file an eligible claim before the next January 1 lien date following that event. A supplemental assessment and the regular annual assessment are distinct, so identify which notice you received when asking the Exemptions Unit about a claim.
When an Assessed Value Seems High
Santa Clara County offers an informal review route for a property owner who disagrees with the assessed value on the Notification of Assessed Value. The Assessor asks the taxpayer to present pertinent factual information about the property’s market value as of the January 1 lien date by August 1 of the current assessment year. The office also provides an informal decline-in-value request page.
Focus the request on facts relevant to the property and its market value for that lien date. Identify the property, the assessment year, the value shown on the notice, and the information you want the Assessor to review. A current asking price or a later change in market conditions is not necessarily information about value on the applicable January 1 date. The Real Property Division handles general valuation questions if you need help identifying the assessment at issue.
Informal Review Versus Appeal
An informal request to the Assessor is different from a formal assessment appeal. The Assessor’s assessed value dispute guidance says applications for a regular assessment appeal must be filed with the Clerk of the Board from July 2 through September 15. After August 15, the Assessor advises taxpayers seeking a reduction to file an assessment appeal with the Clerk of the Board. The appeal is heard by a Value Hearing Officer or an Assessment Appeals Board independent of the Assessor.
For a supplemental assessment or roll correction, the Assessor describes a different filing period: an appeal application must be filed within 60 days of the notice of supplemental assessment or notice of roll correction. These notices can arise in connection with a change of ownership or completed new construction. Read the notice you received and distinguish it from the annual assessed value postcard before choosing a filing period.
An appeal does not suspend the obligation to pay an outstanding property tax bill. The Assessor warns that unpaid bills can result in penalties and interest. If an appeal later lowers the assessed value after you have paid the bill, the Assessor’s guidance says excess taxes paid will be refunded. Direct appeal filing questions to the Clerk of the Board and billing questions to the Tax Collector; the Assessor handles the assessment and informal valuation review.
Business Personal Property Filings
The Assessor’s business personal property guidance explains that business property is appraised annually. Business property owners must file a property statement each year detailing the acquisition cost of supplies, equipment, fixtures, and improvements owned at each location in Santa Clara County. An entity that receives a request-to-file letter or Business Property Statement must submit a completed statement by the date indicated.
Business personal property is handled differently from real property. The Assessor generally bases business property values on original cost, property classification, and type of business, although other approaches may be used when appropriate. Inventory, application software, and licensed motor vehicles should not be reported on the Business Property Statement under the Assessor’s instructions. Gather acquisition cost records by location so the statement reflects the property the Assessor asks you to report.
If the Assessor does not receive a required statement by the delinquency date, state law requires its staff to estimate the property’s value and add a 10% penalty. Businesses whose assessed property value falls below the county’s low-value threshold may avoid a property tax bill, but the Assessor says they must continue to file the required statement. Do not treat the absence of a bill as a substitute for filing.
Paper Signatures and Electronic Records
A paper Business Property Statement must be signed by an authorized person. Depending on the business, that may be the assessee, a partner, a duly appointed fiduciary, or an authorized agent. The Assessor sets additional written authorization requirements for certain agents and employees, and a corporate statement must be signed by an officer or an employee or agent designated in writing by its board of directors. An unsigned or improperly signed statement is not a valid filing and can trigger the failure-to-file penalty.
The Assessor says taxpayers may supply attachments instead of entering information directly on most parts of a paper statement, but the attachments must include all requested information in an acceptable format. The signature section is an exception. The original paper statement still must be returned, refer to the attachments, and be properly signed.
Businesses that used the Assessor’s electronic filing system can obtain an extended values statement showing the basis for enrolled assessed values. Taxpayers who filed electronically on time can also download a copy of their filed Business Property Statement. Access requires the business account number and the business identification number, or BIN, used for electronic filing. These business identifiers serve a different purpose from a homeowner’s assessor’s parcel number.
Ownership Changes and Value Transfers
A change in ownership can raise several separate Assessor questions: whether the property will be reassessed, whether an exclusion applies, whether a supplemental assessment will follow, and whether an existing Homeowners’ Exemption remains in effect. The Property Transfer Unit handles changes of ownership, legal entity ownership, determinations of reappraisability, and exclusions from reassessment. The Recorder handles recorded documents. A question about the assessment effect of a transfer therefore belongs with the Assessor, while a request for the recorded document belongs with the Recorder.
The Assessor’s Proposition 19 overview addresses potential transfers of a qualifying homeowner’s assessed value to a replacement residence and rules affecting certain inherited homes and family farms. These are separate situations with different conditions. The overview identifies qualifying categories for a base-year value transfer, including homeowners over 55, severely disabled homeowners, and homeowners whose homes were destroyed by wildfire or disaster. It also states that applications for a base-year transfer go to the assessor in the county where the replacement property is located.
For a transaction involving a replacement home or inherited property, identify the type of transfer before selecting a form. The Assessor’s forms page is the place to locate its published forms, while the Property Transfer Unit can address questions about ownership changes and reassessment exclusions. Dates, property use, and the location of a replacement home can matter to the assessment, so use the records for the specific transaction when contacting the office.

Assessor FAQs
Can I get help in a language other than English?
Yes. The Assessor’s Office says employees can assist in Spanish, Vietnamese, and Chinese. If you need help understanding a notice or explaining a property question, request language assistance when you reach the office. The Assessor’s Office directory also identifies the unit responsible for each type of assessment issue.
Where can I find sale information for nearby properties?
The Assessor’s Standards Unit handles sales verification letters and access to a two-year list of sales prices. Before requesting information, identify the property or area and the period you want to review. If you plan to use sales as evidence in a valuation dispute, pay attention to whether the sales help establish market value as of the January 1 lien date for the assessment year at issue.
Does an inherited family home keep its assessed value?
Not automatically. Under Proposition 19, an inherited family home may qualify for an exclusion when a qualifying transferee makes it their principal residence. The Assessor’s Proposition 19 overview says the transferee must establish the home as their principal residence within one year of the transfer. It also explains that a qualifying family farm does not have to be the transferee’s principal residence. The property’s value and the circumstances of the transfer can affect the resulting assessment.
Can the Assessor audit my business property records?
Yes. The Assessor says state law requires it to audit the books and records of a significant number of businesses at least once every four years. Other businesses may be audited at random or at the taxpayer’s request. Keep the acquisition cost records and supporting details used for each year’s property statement organized by location so you can explain reported equipment, fixtures, supplies, and improvements if they are reviewed.
