Welcome to the Controller's Office website. My goal is to make the financial information we provide to the citizens of San Mateo County more readily accessible and easy to understand. I hope you find these pages helpful.


The Controller's Office contributes to the financial transparency and operational effectiveness of the County by providing quality accounting, financial reporting, auditing, and payroll services to County departments, local government agencies, and taxpayers.


The Controller's Office maintains the County’s accounting system and produces independently audited and award winning annual financial reports that disclose the fiscal condition of the County to the public. The office also performs internal and operational audits of departments, agencies and contracts and also processes the payroll for all employees. The Controller provides many fiscal services to school districts and special districts throughout San Mateo County.

Our fundamental commitment is to continuously:

  • improve service
  • reduce taxpayer costs
  • upgrade technological infrastructure
  • and enhance the quality , presentation and accessibility of financial information

The Controller's Office is staffed with 42 full-time accountants, auditors and fiscal personnel.
