How do I handle sales tax for online sales in Florida?
Florida requires online sellers to collect and remit sales tax if you have nexus in the state. For remote sellers without a physical presence, economic nexus kicks in when you exceed $100,000 in Florida sales during the previous calendar year. If you’re based in Florida or have inventory, employees, or property here, you already have physical nexus regardless of sales volume.
Once you have nexus, register with the Florida Department of Revenue to get a sales tax certificate. You can do this online through their website. Registration is free and typically takes a few business days to process. Don’t collect sales tax until you’re registered because charging tax without being authorized creates its own problems.
Florida’s sales tax structure has two components. The state rate is 6%, but most counties add a discretionary sales surtax ranging from 0.5% to 2.5%. For online sales shipped to Florida customers, you charge based on the destination address. A customer in Miami-Dade County pays 7% total while a customer in Broward County pays 7%. Palm Beach County is also 7%. These rates can change, so verifying current county rates before each filing period matters.
Your e-commerce platform likely has built-in sales tax calculation or integrates with services like TaxJar or Avalara. These tools automatically apply the correct rate based on shipping address. Manual calculation works for low volume but becomes error-prone and time-consuming as orders increase. The cost of automation is usually worth it compared to the headache of rate lookups and the risk of charging incorrectly.
Filing frequency depends on your tax liability. New registrants typically start with quarterly returns. If your monthly tax collected exceeds $1,000, you’ll be moved to monthly filing. Annual filing is available for very small amounts. Florida requires electronic filing and payment for most businesses. Returns are due on the 1st of the month following the reporting period and late on the 20th.
Keep documentation of what you collected and where you shipped. Your accounting software should track sales tax liability separately from revenue. When you remit to the state, that payment reduces your sales tax liability account, not your income. Sales tax compliance requires clean records because Florida does audit online sellers and will assess penalties plus interest on underpayments.
Common mistakes include charging tax on exempt items, failing to collect on shipping charges when required, and using the wrong county rate. Florida taxes shipping and handling when it’s part of a taxable sale, which catches some sellers off guard. Some products like groceries and certain medical items are exempt, but the rules are specific.
If you’re selling in multiple states, which most online sellers are, the complexity multiplies. Each state has different nexus thresholds, rates, exemptions, and filing requirements.
