Also in Florida.
Our Residents' Association is incorporated under Florida Statute 617 and recognized by the IRS as a 501(c)(4) tax-exempt organization. We collect from residents and distribute to employees, though in our case only annually. For convenience in the bookkeeping, we keep these funds in a separate checking account. (The Association has other activities.) This method allows us to define these as "gifts", not tips. The Residents' contributions are, of course, not tax-deductible, and the gift is not taxable for the employee.
In our community, we have a Residents' Association and a Residents' Council (Florida Statute 651) because the Association existed long before 651 mandated Councils. For all practical purposes, they are one and the same, the elected Council is the Board of Directors of the Association. I know of new facilities that have simply incorporated their Council so they don't have to deal with the dual structure. If you do incorporate and especially if you seek 501(c)(4) status, there are forms to be filed even though it is unlikely you'll have actual taxes to pay.
You could, theoretically, accomplish this as an unincorporated association but finding a bank that will give you a bank account will be a challenge. If unincorporated, there is also concerns for personal liability.
If this goes through the employer's payroll system it is going to be taxable to the employee, there is no way around that.
