Fictitious Business Names – Opening a Business
Few things are as important to a business as its name. That’s how your customers find your business and you begin to build your reputation and clientele. To open a business that does NOT have the legal name of the owner, you must file a Fictitious Business Name (FBN) Statement. Fictitious Business Names (FBN) Applications are good for 5 (five) years and then they must be renewed. Learn more about filing a fictitious business name statement. Search the FBN database to see if that business name is already in use in San Mateo County.
Business Property Statement Form 571-L:

If you own taxable personal property with an aggregate cost of $100,000 or more on January 1, or if the Assessor has requested a statement be filed, you are required by law to file a property statement that details the costs of all supplies, equipment, fixtures, leasehold improvements, land improvements, and land, as well as other requested information for each business location. Filing forms are mailed out the first week of February. The current year property statements and valuation factors will be posted to the website for download at about the same time. They are due April 1st and late if received after 5:00 p.m. on May 7th. Late filing penalties will apply for property statements received after May 7th.
Small business owners with personal property with a value of less than $7,500, may be exempt from personal property tax assessment in San Mateo County but are still required to file a statement if requested by the Assessor. For more information, call (650) 363-4501.

Financial Disclosure Form
The Political Reform Act (Gov. Code sections 81000- 91015) requires most state and local government officials and employees to publicly disclose their personal assets and income. They also must disqualify themselves from participating in decisions which may affect their personal economic interests. The Fair Political Practices Commission (FPPC) is the state agency responsible for issuing the Statement of Economic Interests, Form 700, and for interpreting the law's provisions. Most statements are filed with the agency and originals are forwarded to the Fair Political Practices Commission. These reports are open to public inspection and may be reproduced upon request.

Exclusion for Builders of Four or Fewer Single-Family Residences
Builders of four or fewer single-family residences may be exempted from a supplemental assessment on new construction that is built for sale.
The builder must file a claim for exclusion within 30 days of starting construction. The form is available at the Assessor's Division and should be completed and returned to that office.
If the builder does not file the form within 30 days of starting construction, a supplemental assessment for the value of the new construction is assessed to the builder upon completion of construction.
If the exclusion is granted, a supplemental assessment is not created until the property is sold.
Decline in Market Value (Proposition 8) - Property Tax Relief
The assessed value of a property should never be higher than the property's value on the open market. Occasionally, market forces and other factors will cause a property's value to decline significantly enough to create that situation. In these cases, the Assessor may lower the assessed value of any real property if it is higher than the market value as of January 1.
Each case is reviewed individually at the request of the property owner. The Assessor considers both land and improvements when determining the January 1 market value.
Disabled Veterans’ Exemption
Disabled veterans of military service may be eligible for up to a $187,399 property tax exemption. Qualifying veterans must have been disabled due to a service-related injury or disease while in the armed forces, and must be a resident of California as of January 1 of the year in which they are applying for an exemption.
Veterans with 100% disability, or partially disabled and unemployable, or their unmarried surviving spouses, are eligible for up to a $124,932 exemption. If total household income does not exceed $56,101, the 100% disabled veteran may qualify for up to a $187,399 exemption.
Qualifying income levels are subject to change.
For information, call (650) 363-4500 or e-mail the Assessor's Division
If a calamity such as fire, earthquake or flood damages or destroys your property, you may be eligible for property tax Saving, provided the loss exceeds $10,000. In such cases, the Assessor's Division will reappraise the property to reflect its damaged condition. If the property is rebuilt in a like or similar manner to the original, the property will retain its previous value for tax purposes.
To qualify for property tax Saving, you must file a calamity claim form with the Assessor's Division within one year from the date the property was damaged or destroyed.
If you own a home and occupy it as your principal place of residence on January 1, you may apply for an exemption of $7,000 from the home's assessed value, which reduces your property tax bill. There is no charge for filing for the Homeowner Exemption. New property owners will automatically receive an exemption application in the mail. Homeowner Exemptions may also apply to a supplemental assessment if the property was not previously receiving a Homeowner Exemption on the annual Assessment Roll.
Please note that California law provides for only one Homeowner Exemption per owner at their principal place of residence, so a second home would not qualify for the exemption.
San Mateo County residents may request a Homeowner Exemption claim form from this website. Residents of other counties should contact their local assessor's office for these forms.
To request a Homeowner's Exemption claim form, include the property address, your mailing address and/or your Assessors Parcel Number.

Property Tax Postponement for Senior Citizens, Blind, or Disabled Persons
On February 20, 2009, the Governor signed Chapter 4, Statutes of 2009, which immediately suspends the Senior Citizens' Property Tax Deferral Program. This legislation prohibits the filing of claims for property tax postponement and prohibits the Controller for accepting claims for property tax postponement pending modification or repeal of this new law. However, the Controller's Office will continue processing claims postmarked pior to February 20, 2009. For the most current information on the PTP programe please visit our website at sco.ca.gov.
The State of California may pay all or part of the property taxes on the home or mobile home of persons who are blind, disabled, and older than 62 years of age and who have an annual income of $24,000 or less. This deferred payment is a lien on the property and becomes due upon sale, change of residence, or death.
The application process requires the homeowner to file a claim form with the California State Controller's Office. The Controller will establish an account to pay all or part of property taxes on the home. A Property Tax Postponement lien will be recorded on the home. Simple interest will accrue on the postponed amount at a rate set in July by the California Legislature. Contact the State Controller's Office, toll free, at 1 (800) 952-5661.
The lien and interest are not due until the resident moves out of the home, sells or otherwise conveys title to another or dies without a spouse or other qualified individual continuing to reside in the home. Repayment is required if future property taxes or other senior liens become delinquent.
The filing period for property tax postponement is the third Monday in May through December 10. A claim must be filed each year that the homeowner wishes to participate in the program. For more information and an application, call the State Controller's Office, toll free, at 1 (800) 952-5661.

Williamson Act Land Conservation Program
Agricultural Preserve/Williamson Act Questionnaire (January 1, 2016 – December 31, 2016)
In accordance with the Williamson Act, the Assessor is required by law to appraise land restricted by a land conservation contract on the basis of current economic rent. In order to appraise land by this method, it is necessary for the Assessor to request current data on income, rentals, expenses and production for the particular type of operation involved.
Each year, the Assessor’s Division mails the Agricultural Preserve/Williamson Act questionnaire to eligible property owners to assist in the discovery of this information. Per Revenue and Taxation Code Section 441(d), the property owner is required to furnish the Assessor, within a reasonable time frame, with the relevant data necessary for an accurate appraisal. We kindly ask that each property owner complete and return the questionnaire by March 3, 2017.

Please contact the Assessor’s Division for information regarding the following exemptions:
California law requires every state or local governmental entity that is the fee owner of real property in which one or more taxable possessory interests have been created or renewed to provide the assessor of the county in which the property is located information identifying the holder(s) of a taxable possessory interest, the property involved, and the terms and conditions of the agreement giving rise to the taxable possessory interests. The agency may provide the county assessor the information on either (1) a preliminary change in ownership report or change in ownership statement, or, (2) an annual real property usage report. If, as of January 1 this year, your agency owns any property with taxable possessory interests that have not already been reported on a preliminary change in ownership report or on a change in ownership statement, you are required to complete and file this form with the county assessor by February 15.
An owner can request to have their parcel split or combined if an APN can be described/delineated by existing parcel and or lot lines and the parcels of land in the opinion of the assessor can be redefined without compromising ownership, tax rate areas, general use and assessment of the land. In order to make a change, the owner must put their request in writing (on the form listed below), meet the legal requirements and mail or hand-deliver the signed request to the San Mateo County Assessor-County Clerk-Recorder's Office, Assessor’s Division.
What is an assessment parcel? An “assessment parcel” is a land area that is under one ownership and for general use. Parcels are referred to by their “assessment parcel number”or APN. An APN delineates land area as it is owned rather than as it may have been plotted on a subdivision or other map. It is an area of land that in the opinion of the assessor should be included under one description for assessment purposes after consideration of all legal factors. (Assessor Handbook 215)
