For providers in Port St. Lucie, entity status decides what the purchasing department owes:

A non-profit hospital is generally relieved of tax on purchases made for its exempt purpose, and a for-profit one on the same street is not — so the entity classification decides the invoice before the item does. The line is not the building: the gift shop, the cafeteria and the parking structure are unrelated business activities and can be taxable at 7.000% inside an otherwise exempt institution, while capital equipment on the scale of an MRI or a surgical robot usually is exempt with the documentation in place. Contracted laundry, food service and medical waste each follow their own Florida treatment. The certificate mechanics are in the exemption certificate guide.

Wayfair, a seller with no premises, staff or stock anywhere near Port St. Lucie can still be required to register in Florida and charge 7.000% on what it ships here — presence stopped being the trigger and volume took over. The thresholds that decide it are in the table below; what they do not tell you is that crossing them obliges you to collect at the buyer's local rate, not a state average, which is why Port St. Lucie and its neighbours have to be priced separately.

Audit & Compliance Warning: Because combined tax rates combine state and local tax components, calculating tax based purely on ZIP codes can lead to errors. Many ZIP codes span multiple municipal boundaries with differing rates. For precise auditing, always use address-level geo-lookup.
