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.
To promote the County's operational effectiveness, and ensure its financial transparency and integrity, by providing quality accounting, audit and financial reporting services.
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 audits of departments’ operations. The Controller's Office is staffed with 46 full-time accountants, auditors and fiscal personnel.
