As a property owner of San Mateo County, you may have wondered how your tax dollars are distributed. The following chart provides some helpful tax distribution and service information. The chart illustrates the distribution of the 1% ad valorem tax (based on the assessed value).


Although schools continue to receive the largest portion of your tax dollars, changes in State laws have reduced their share. The County provides health, welfare, human services and criminal justice programs with its portion. Cities provide fire, police and other community services. Special Districts, such as Flood Control and Sequoia Healthcare District provide other services to the community for further information please visit the San Mateo County Controller website at https://controller.smcgov.org/ or call (650) 363-4893.
