Florida Economic Nexus: What Remote and E-Commerce Sellers Must Know About the $100,000 Threshold

Starting July 1, 2021, out-of-state sellers that topped $100,000 in taxable Florida remote sales during the prior calendar year became obligated to register with the state, collect both state and county-level taxes on those transactions, and file all returns electronically.^[1] The rule applies to any seller located outside Florida, whether in another U.S. state or abroad, that crosses the threshold. Once triggered, the obligation begins on a going-forward basis for the calendar year following the year in which the seller crossed the threshold.

For South Florida businesses that sell across state lines or e-commerce sellers that ship into Florida from warehouses outside the state, this rule creates a compliance obligation that does not require a warehouse, store, or office inside Florida. The threshold is based on sales volume, not physical presence. If you are unsure whether your sales activity crosses the threshold, our Florida sales tax services team can help you assess your exposure.

The obligation covers not only Florida's state sales and use tax but also any applicable discretionary sales surtax.^[1] Florida counties levy discretionary surtaxes on top of the state rate, which means the amount a remote seller must collect and remit depends on the county where the buyer receives the goods or services, not just the statewide rate.

For e-commerce sellers shipping physical goods to Florida addresses, this means tracking the destination county for each transaction and applying the correct combined rate. Businesses selling into Florida frequently underestimate their liability by applying only the state rate and ignoring county surtaxes. Our e-commerce + Amazon seller tax help page covers how this affects multi-channel sellers in more detail.

Florida's deadline for sales and use tax is the 1st of the month following each reporting period; any amount still unpaid after the 20th is considered late.^[4] Plan electronic payment well before the 20th to avoid penalties.

Filing frequency depends on the total amount of sales tax a business collects each year. High-volume sellers file monthly; lower-volume sellers may qualify for quarterly, semiannual, or annual filing. Businesses that file and pay electronically on time may claim a collection allowance of 2.5% (.025) of the first $1,200 of tax due, not to exceed $30 per reporting location.^[3]

Florida enforces two distinct penalty categories against delinquent or non-compliant sellers. The first is a late-filing charge: 10% of the unpaid tax, with a floor of $50 regardless of the amount due.^[2] The second category applies to sellers who skip the required electronic channel: each missed electronic return triggers a $10 assessment, and each missed electronic payment triggers an additional $10 assessment, both on top of any other penalty that may also apply.^[5]

For a remote seller with a newly triggered nexus obligation, both penalty categories can apply simultaneously: back tax on uncollected amounts, the 10% charge on that tax, and $10 per period for non-electronic filings. Working with a qualified small business accounting practice from the moment you cross the threshold limits exposure significantly.

Registering with the Florida Department of Revenue is the first step, not the last. Once registered, a business may need to file additional documentation with the state tax board, and these filings most often need to be completed within 30 to 90 days after registering.^[6] Failing to complete post-registration steps correctly can result in account suspension or penalties accruing before the first return is filed.

Florida's system is also not static: if annual sales into Florida fluctuate, filing frequency can change from one year to the next, and registration must be updated accordingly. Compliance is an ongoing obligation, not a one-time setup. Businesses that hit Florida's threshold are often candidates for a business structure review.
