Florida Sales Tax Nexus — Frequently Asked Questions

What is the sales tax nexus threshold in Florida?

The economic nexus threshold in Florida is $100,000 in sales revenue during the previous calendar year. Once you exceed this amount, you are required to register with Florida and begin collecting sales tax on all taxable sales to Florida customers.

How does Florida measure the economic nexus period?

Florida looks at your total taxable sales in the previous calendar year (January 1 – December 31). If you exceeded $100,000 in the prior year, you have nexus at the start of the following year. Keep an eye on year-end totals to plan your registration timing.

Does Florida include marketplace sales in the nexus threshold?

Yes. Florida includes marketplace sales in its economic nexus threshold calculation. Sales you make through Amazon, Etsy, or other marketplace facilitators count toward the $100,000 threshold alongside your direct-channel sales.

How do I register for sales tax in Florida?

Register online at Florida's official tax portal: https://floridarevenue.com/taxes/registration/. Have your federal EIN, business legal name, mailing address, and anticipated first taxable sale date ready. Most states complete registration instantly and issue a permit number you can use immediately.

What happens after I exceed the Florida nexus threshold?

Once you meet the Florida economic nexus threshold, you must register, collect the correct Florida sales tax rate on all taxable sales, file regular returns (frequency depends on your sales volume — monthly, quarterly, or annually), and remit the collected tax by each due date. Retroactive liability can apply to sales made after you crossed the threshold but before you registered, so acting quickly after exceeding the threshold limits your exposure.
