The Office of Finance comprises twelve divisions, each with important responsibilities to support the overall financial health of the City of Los Angeles and all of the stakeholders it serves, from residents and visitors, to businesses, both large and small. On an annual basis, Finance is responsible for the collection of over $3 billion in revenue from various sources including taxes, licenses, fees, and permits which pay for numerous essential municipal services to City residents and businesses. From tax discovery units to customer support, the tax collection division secures the inflow of funds to keep the City operating. Finance is the custodian of all money deposited in the City Treasury and all securities bought by the City, which involves building investment strategies that mitigate downside risk and capturing upsides from the market. Treasury actively manages the City's $9.7 billion General and Special Pool investment portfolio, and processes over $40 billion through treasury services.
