Those proposals came from Democrats and Republicans alike, and from several legislators representing Clark County.Most of the bills in question impose fees on members of a particular industry, or other groups, such as vehicle owners or outdoors enthusiasts. Had all of the proposals passed, they would have raised at least $3 billion in new revenue in the next decade.This year, one of the largest tax or fee bills to pass was determined by OFM to raise at least $1 billion in the next 10 years. The measure, which was included in the operating budget, adds a tax on hospitals to pay for Medicaid hospital services. Medicaid is a health-care program for the poor.
