Does this apply to your business in Florida?
Yes, if you operate in Duval County and accept payment for goods or certain services, you must collect and remit sales tax to the Florida Department of Revenue. Florida’s rule is straightforward: tangible personal property (physical items you sell) is taxable unless a specific exemption applies. Services, however, are generally not taxable unless the statute lists them as taxable. If you’re uncertain whether your product or service is taxable, the Department of Revenue website and its tax guides are your reference.
How the rate works
Florida’s sales tax system has two layers: a state rate and a county surtax. The state sets a base rate that applies everywhere. On top of that, Duval County adds its own local surtax. The combined rate—what you actually charge your customers—is the sum of both. Because county rates can change and vary across the state, you should always check the current combined rate for Duval County before you file. The Florida Department of Revenue publishes the current rates on its website, and many tax software platforms include rate calculators to keep you up to date.
Understanding this structure matters because it affects how you report. On your DR-15 return, you’ll see lines for state collections and county collections—they’re separate on the form, even though you charge one combined rate to your customers. Your responsibility is to collect the right total amount, separate it properly by category on your return, and pay both the state and the county their share by the deadline.
How to file step by step
Filing the DR-15 return (Florida’s monthly sales tax return) follows a predictable process on the Florida Department of Revenue website. First, you’ll need to register with the Department if you haven’t already and set up your account online. Once registered, you log in to the Department’s system and access the DR-15 form for the month you’re reporting.
The form guides you through sections: it asks for your gross sales, then your exempt sales, then your taxable sales. The taxable sales figure multiplied by the combined rate (state plus county surtax) gives you the total tax collected. The form then separates that total into what goes to the state and what goes to the county, based on their respective rates. You enter the amount you remitted (paid), and if there’s a difference, that becomes your balance due or refund.
The deadline is typically by the 20th of the month following the month you’re reporting. So sales from January are reported by February 20th. If you miss that deadline, penalties and interest accrue, so setting a calendar reminder is essential. Many business owners file electronically through the Department’s online portal, which reduces errors and provides immediate confirmation of filing.
If you’re new to the process or want to walk through each screen step by step, the Department of Revenue offers tax guides and this training on the role of the Florida Department of Revenue covers the fundamentals in detail. Taking time to understand the process the first time prevents costly mistakes later.
Common mistakes
Mixing up taxable and exempt sales. Many business owners lump all sales together instead of separating taxable goods from exempt services or items that have exemptions. If you sell both, spend time categorizing accurately. Underreporting taxable sales or overclaiming exemptions triggers audits and back-tax demands. Go through your records by transaction type, not just total revenue.
Forgetting to account for the county surtax separately. The combined rate is easy to apply when you ring up a sale, but when you file, the DR-15 form asks for state and county collections separately. If you only report the state portion or misallocate the county share, your return won’t reconcile, and the Department will contact you. Keep records that show both the gross amount and the split between state and county from the start.
Filing late or not at all. The 20th of the following month comes fast. Late filings accrue penalties even if you pay the tax owed. If you’re juggling multiple tasks and lose track of the deadline, set automatic calendar reminders, or consider using a tax service that tracks deadlines for you. Filing on time, even if the amount is small, keeps you off the Department’s radar.
Not keeping records. If you don’t retain receipts, invoices, and a running total of sales and tax collected, you can’t defend your return if audited. The Department asks for documentation, and if it’s missing, they may assess based on their own calculation. Keep records by month, filed so you can pull them within minutes if needed.
Frequently Asked Questions
Is there a difference between the state sales tax rate and Duval County’s rate?
Yes. Florida sets a state rate that applies everywhere. Duval County then adds a county surtax on top. What you charge customers is the combined rate. The DR-15 form separates collections by state and county, so you need to know both rates and track them separately in your accounting, even though you charge one total to customers.
What happens if I file the DR-15 late?
Late filings incur penalties and interest. The Department of Revenue assesses these charges automatically when a return is submitted after the 20th of the following month. Even if you pay the tax owed in full, the late fee still applies. Filing on time is one of the easiest ways to keep compliance costs down.
Do I have to register with the Florida Department of Revenue before I start collecting sales tax?
Yes. You must register and receive a sales tax registration number before you collect or owe sales tax. Most registrations are done online through the Department’s website. Once registered, you can start filing returns. If you haven’t registered yet, do it immediately to stay compliant from this point forward.
What sales are exempt from Florida sales tax?
Tangible personal property is taxable unless a specific exemption applies (such as certain groceries or prescription drugs). Most services are not taxable unless the statute lists them. Common exempt items have exemption certificates you file with the customer, like resale certificates. The Florida sales tax guide covers exemptions in detail, so review it to confirm which of your sales qualify.
Can I use tax software or do I have to file on the Florida Department of Revenue website directly?
You can file directly on the Department’s website, or you can use third-party tax software that integrates with the Department’s system. Many small business owners use accounting platforms that track sales and calculate tax automatically, then file the DR-15 for them. Whichever method you choose, make sure the deadline is met and your records are accurate.
