Discretionary sales surtax is an additional sales tax that Florida counties can impose on top of the state’s 6% sales tax. When a customer buys something taxable, you collect the state tax plus whatever surtax applies based on the county where the sale happens. The combined rate in Palm Beach County is 7% total, with the 1% surtax going to the county for infrastructure and services.

The surtax only applies to the first $5,000 of each taxable item or transaction. If someone buys equipment for $8,000, you charge the surtax on the first $5,000 and only state tax on the remaining $3,000. This cap exists to limit the burden on larger purchases while still generating county revenue from everyday transactions.

County rates vary across Florida. Palm Beach County charges 1%, Broward County charges 1%, and Miami-Dade County charges 1% as well. Some counties charge as high as 1.5%. If your business sells across multiple counties or ships to customers in different locations, you need to apply the correct surtax rate for each destination.

Point of sale systems and accounting software can handle surtax calculations automatically if they’re configured correctly. QuickBooks and most retail POS systems have Florida surtax settings built in. The setup requires entering your business location and enabling destination-based taxation so the system applies the right rate based on where goods are delivered or services performed.

The Florida Department of Revenue publishes updated surtax rates every year. Counties can change their rates through voter referendums, so what applied last year might not apply this year. Check the current rates at the start of each calendar year to make sure your systems are calculating correctly.

Filing and remitting surtax happens alongside your regular sales tax compliance. The state collects both together on your sales tax return. You don’t file separately with each county. The state handles distribution to the counties based on where your sales occurred.

Common mistakes include not collecting surtax at all, applying the wrong county rate, or forgetting the $5,000 cap on larger transactions. These errors create liability that shows up during audits. The Florida Department of Revenue audits businesses regularly and goes back several years when they find issues.

If you’re selling across South Florida or have questions about whether you’re handling surtax correctly, a Boca Raton fractional CFO or controller can review your setup and make sure you’re collecting and remitting the right amounts. Getting this wrong for years creates a tax liability that’s expensive to fix.
