Florida requires out-of-state sellers to collect sales tax once their taxable sales into Florida exceed $100,000 in the previous calendar year. This is economic nexus, and unlike physical nexus, it does not require any presence in the state. The threshold is measured by taxable sales, so exempt items do not count, there is no separate transaction-count test, and sales made through a marketplace that collects on your behalf do not count toward your number. If you cross the threshold, you must register with the Florida Department of Revenue, collect, and remit.
For most of the history of sales tax, a state could only require a business to collect if it had a physical presence there. That changed when the U.S. Supreme Court ruled that states may require remote sellers to collect based on their economic activity alone. Florida adopted that approach, and the result is economic nexus: if you sell enough into Florida from another state, you have to collect Florida sales tax even though you have never set foot in the state. This article explains the threshold, how it is measured, and what to do if you have crossed it. For the full picture of how Florida sales tax works, see our complete guide to Florida sales and use tax.
What Is Economic Nexus?
Nexus is the connection between a business and a state that creates a duty to collect sales tax. Traditionally that connection had to be physical, an office, a store, employees, or inventory. Economic nexus is different. It is a connection based purely on how much you sell into a state, with no physical presence required at all.
The practical effect is that an online retailer in Texas, a software-and-goods company in New York, or any remote seller shipping products to Florida customers can be required to register and collect Florida sales tax once its Florida sales are large enough. Where your business sits no longer decides the question; how much you sell into Florida does.
The Florida Economic Nexus Threshold
Florida’s threshold is a single number: $100,000 in taxable sales delivered into the state during the previous calendar year. A remote seller that exceeds that amount must register and begin collecting. A seller that stays under it is not required to collect on the basis of economic nexus, though physical presence is a separate trigger that can still apply.
Florida’s rule is comparatively simple, because it relies on that one dollar figure. Some states add a second test based on the number of separate transactions, so that a high count of small sales can create nexus even below the dollar threshold. Florida does not. The transaction count is irrelevant here; only the taxable sales total matters.
How the Threshold Is Measured
Three details decide whether you have crossed the line, and each one catches sellers off guard.
- Taxable sales only. The threshold counts taxable sales into Florida. Exempt sales, and items that are not taxable in Florida, do not count toward the $100,000. A seller whose Florida revenue is largely exempt may be below the threshold even with substantial total sales.
- The previous calendar year. The test looks back at your taxable Florida sales over the prior calendar year. Crossing the threshold in one year creates the obligation going forward.
- Marketplace sales are excluded. Sales you make through a marketplace that collects and remits Florida tax for you do not count toward your own threshold. Only your direct sales, such as through your own website, count.
| Physical nexus | Economic nexus | |
| What creates it | A physical presence in Florida | Sales volume into Florida |
| Measurement (the trigger) | Office, staff, or inventory in the state | Over $100,000 in taxable sales last year |
| Who it catches | In-state and fulfillment-center sellers | Remote and online sellers |
| When collection starts | When the presence begins | First day of the month after you cross |
The two triggers are independent. You can have physical nexus without hitting the economic threshold, or economic nexus with no presence at all, and either one alone requires you to collect.
When You Have to Start Collecting
Once your taxable Florida sales pass $100,000 for the prior calendar year, the obligation begins on the first day of the following month. That gives a short window to register and set up collection, which is not much time if you only notice the threshold after the fact. The cleaner approach is to track your Florida sales as they build, so that crossing the line is something you plan for rather than discover later.
Marketplace Sales and Your Threshold
This is the point that trips up sellers who use both a marketplace and their own store. If you sell through a marketplace that is registered to collect Florida tax, that marketplace handles the tax on those sales, and those sales do not count toward your personal $100,000 threshold. Your direct sales, through your own website or other channels, are what count.
The mistake runs both ways. Some sellers assume all of their volume counts and register when they did not need to. Others ignore their direct sales because the marketplace is handling its share, and miss the point at which their own-channel sales crossed the line. Separating the two is essential to getting the answer right.
What to Do If You Have Nexus in Florida
If you have crossed the threshold, the steps are to register with the Florida Department of Revenue using the Florida Business Tax Application, begin collecting tax at the correct destination-based rate for each customer’s county, and file returns on the schedule the Department assigns. The Florida Department of Revenue’s sales and use tax pages set out the registration and filing details.
The harder situation is discovering that you crossed the threshold months or years ago and never registered. In that case you may have uncollected tax that you, not your customers, are now liable for, and the exposure grows the longer it goes unaddressed. This is not a do-it-yourself cleanup. A Business CPA Tax Resolution Case Analysis reviews how far back your exposure runs, what you actually owe, and the realistic options for resolving it while limiting penalties. Sorting it out deliberately is far better than waiting for the Department to find the gap.
