Credit card processing and merchant services in Port St. Lucie, FL
Port St. Lucie gained about 63,000 residents between April 2020 and July 2025, by Census Bureau estimates. Every new business here starts with St. Lucie County's 7% rate and a choice about card fees.
The Census Bureau's QuickFacts table puts Port St. Lucie at 268,062 residents in July 2025, up from an April 2020 estimates base of 204,826. That's about 63,000 more people in a little over five years. If you're opening a business here, get the tax setup right before the first sale. A wrong rate found months later means refunds to customers or tax you pay out of your own pocket.
St. Lucie County's combined rate is 7%. The Department of Revenue's surtax form splits the county's 1% into two half-cent surtaxes, one for school capital outlay and one for local government infrastructure, and lists the school half as extended. The Department updates that form every November, so read the new one before each January.
Deliveries follow the customer, not your store. Florida applies the surtax of the county where the item is delivered, so a Port St. Lucie business delivering into Orange County charges 6.5% and one delivering into Hillsborough County charges 7.5%. Big-ticket sellers have one more rule: for certain transactions, only the first $5,000 is subject to surtax. If that covers your product, a $6,500 item sold here carries $390 in state tax plus $50 in surtax, or $440, instead of $455 at a flat 7%.
On card fees, Florida's Attorney General says the old surcharge ban was struck down, so a disclosed credit card surcharge is an option within Visa's and Mastercard's caps. The statute also leaves discounts for paying by cash or check outside its reach, provided every customer is offered one. Our Florida page covers both, and our cash discount guide shows how cash pricing is usually posted. Clearo prices on interchange-plus, and a free statement review shows what you pay now.

Common questions
What makes up St. Lucie County's 7% sales tax?
Florida's 6% state rate plus two half-cent county surtaxes, one for school capital outlay and one for local government infrastructure. The Department of Revenue's DR-15DSS form lists both and shows the school surtax as extended. The Department updates the form each November, and new surtax rates take effect on January 1, so check it before each new year.
Which rate applies when a Port St. Lucie business delivers to Orlando or Tampa?
The rate of the county where the item is delivered. Orange County, where Orlando is, comes to 6.5%, and Hillsborough County, where Tampa is, comes to 7.5%. Your POS or online checkout needs the delivery address to get this right, and the Department of Revenue's address lookup shows the county and surtax for any Florida address.
How does the $5,000 surtax limit change the tax on a big sale in St. Lucie County?
For certain transactions, Florida applies the county surtax only to the first $5,000. On a qualifying $6,500 item, that means $390 in state tax and $50 in surtax, $440 in total, rather than $455. On a qualifying $20,000 item, the surtax still stops at $50. Ask your accountant which of your products qualify.
Can I offer a cash discount in Port St. Lucie instead of a card surcharge?
Yes. Florida's surcharge statute doesn't apply to a discount offered to get customers to pay by cash, check or another method that doesn't use a credit card, as long as the discount is offered to all prospective customers. Post the card price as your regular price and show the discount for cash. Our dual pricing vs surcharging guide compares the two setups.
