Each year state decision-makers are tasked with balancing constitutional, statutory, and federal requirements with a host of other considerations, such as competing policy priorities, caseload growth, and the health of the state’s economy to create a budget. Although the budget is funded with a variety of revenue sources, state taxes provide a significant portion of the revenue Colorado uses to fund its operations.
