TOT and VRBLT Administrative and Audit Services

San Mateo County is the 14th largest county in California, with a population of approximately 725,000. The Treasurer-Tax Collector is responsible for administering and enforcing the collection of Transient Occupancy Tax (TOT) and Vehicle Rental Business License Tax (VRBLT) from businesses operating in the unincorporated areas of the County. TOT and VRBLT, currently levied at rates of 10% and 2.5% respectively, are important sources of non-property tax revenue for the County. TOT is imposed on transients who occupy lodging facilities—including hotels, motels, campgrounds, short-term rentals (STRs), and vacation homes—for 30 consecutive calendar days or less. Operators subject to these taxes are required to register with the County, obtain the appropriate certificates, and report and remit taxes on a quarterly basis. In San Mateo County, vehicle rental businesses operating in unincorporated areas are required to obtain a Vehicle Rental Business License and remit a business license tax equal to 2.5% of gross rental receipts, reported to the County Tax Collector. The Treasurer-Tax Collector is seeking a qualified and reliable partner to provide comprehensive TOT, STR and VRBLT collection services. These services include billing and collecting, compliance and monitoring, customer support for TOT, STR and VRBLT operators, administrative and audit assistance as described in Section 2 (Scope of Work), and expertise in reviewing municipal codes and advising on legislative or regulatory changes impacting revenue collection. The selected solution should enhance operational efficiency, reduce administrative costs, and improve compliance with County ordinances. The Treasurer-Tax Collector requires a firm with a proven track record and demonstrated capacity to accurately and timely identify TOT, STR, and VRBLT operators that are out of compliance. In recent years, the growth of short-term rental platforms such as Airbnb and VRBO has significantly expanded STR activity within the unincorporated areas of San Mateo County. As a result, the County seeks partners capable of leveraging data and analytics to identify potential non-compliant STR operators. Accurate data collection, reporting, and analysis are critical to ensuring effective revenue administration and compliance enforcement.
