Welcome to San Mateo County Revenue Services

The trained, professional Revenue Services staff provides billing and debt-collection services for the Courts and County departments/divisions that do not perform one or both of those functions themselves. We collect accounts receivable as well as court-ordered reimbursements, fines, and other funds due.

Revenue Services currently provides billing and/or collection services in these areas:

  • Court fines and fees
  • Traffic fines and fees
  • Private Defender fees
  • Medical billings
  • County Recorder fees
  • Probation fines and fees
  • Public Assistance Over-payments (Human Services Agency)
  • Victim Restitution
  • Environmental Health
  • Sheriff (Work Program, Work Furlough, Electronic Monitoring)

Revenue Services works to collect debts owed to these offices in a reasonable, compassionate way – while we can apply stringent legal means when necessary, we prefer to work with you to develop a realistic repayment plan. Please call (650) 363-4155 for further information about these options.


Our cashier windows will be closed on Tuesday, February 25, 2020 from 2:30-4:00 pm.

Our office hours are 8:30 AM-5:00 PM.
