Comptroller Operations

In addition to judicial and administrative responsibilities, as the Comptroller, Clerk Juan Fernandez-Barquin acts as the Chief Financial Officer, accountant, and investor and custodian of county funds. Our Comptroller Operations Departments support this constitutional role by ensuring the proper use of public resources, safeguarding county assets, and promoting transparency through strong internal controls, accurate reporting, and responsible fiscal oversight.

This vital work helps maintain financial stability and strengthens public trust by ensuring that all county funds are managed lawfully, efficiently, and transparently.

As Comptroller we provide a wide range of essential accounting and financial management services for all Miami-Dade County Departments and some Constitutional Offices.

Our core responsibilities include:

• Tracking countywide expenditures and financial activity
• Managing payroll for thousands of county employees
• Maintaining the county’s accounting system and recording all fiscal actions taken by the Board
• Processing all disbursements
• Reviewing and monitoring county budgets

We uphold fiscal integrity by conducting independent audits and reviews to ensure county funds are spent in accordance with the law. Always protecting taxpayer dollars from fraud, waste, and abuse.

To strengthen accountability, we also:

• Pre-audit county expenditures before payment
• Review contracts for compliance and financial impact.
• Conduct post-audits to evaluate internal controls and operational effectiveness.
• Prepare reports recommending improvements to strengthen financial management.

We also manage county investments, ensuring public funds are secure while achieving a responsible return on investment. Additionally, we maintain financial records and prepare comprehensive financial reports for the Board of County Commissioners. To promote transparency, we publish accessible financial documents, such as, the Annual Comprehensive Financial Report (ACFR), giving residents clear insight into how taxpayer dollars are managed and spent.

Our Comptroller Operations serves as the central hub for financial accountability, with two core operational areas:

Financial Reporting • Disbursements • Payroll and Revenue Management

Our Comptroller Finance Operations Department manages the financial framework of Miami-Dade County and the COCC, including accounting, budget compliance, disbursements, revenue processing, and financial reporting. Our team ensures statutory compliance, supports daily financial operations, and maintains the internal controls necessary for responsible stewardship of public funds.

Independent Oversight • Risk Management • Continuous Improvement

Through our Comptroller Audit Operations Department, we conduct independent audits, reviews, and assessments across COCC functions, county departments, and external entities with financial relationships to Miami-Dade County. This work helps ensure accuracy, identify risks, strengthen internal controls, and recommend improvements that enhance transparency and efficiency.
