Anyone in Florida pay county business Tax Receipts?

[Mike Nelson]

I just started my first LLC in Florida and noticed the county requires a business tax receipt for ALL businesses that do business in the county. However, I searched the county records and foun that 1 out of 20 of the known real estate investors in the county has a record of paying the business tax. Anyone dealt with this before? Why would none of the others have a records of payment? There is nothing in the exemptions for real estate investors.
