You’ve been selling consistently, your customer base is growing, and suddenly your accountant or a tax notice flags that you’ve been charging the wrong sales tax rate—or worse, you’ve collected under what you owed. Florida county surtax rates vary dramatically depending on where your business operates and where your customer is located. The state sets a 6 percent baseline, but then each county adds its own surtax on top. If you’re not clear on which rate applies to your transactions, you could be undercollecting tax, overpaying later, or filing incorrect numbers on your sales tax return. This is where precision matters, and it’s also where most small business owners—especially those who haven’t had formal tax training—run into trouble. The good news: understanding the structure is straightforward once you know what you’re looking at.

Does this apply to your business in Florida?
If you sell tangible personal property in Florida or operate a service business that falls under a taxable category, you must collect and remit sales tax at the correct combined rate for each county where your customer is located. The Florida Department of Revenue sets the rules: tangible items are taxable unless specifically exempt by law; most services are not taxable unless they’re explicitly listed in Florida Statute 212. County surtaxes are mandatory—you can’t opt out—and they’re in addition to the state 6 percent rate.
How the rate structure works
Florida’s sales tax operates in two layers. First, there’s the state rate of 6 percent. Second, each of Florida’s 67 counties can levy its own discretionary surtax to fund local projects—road improvements, school facilities, transportation systems, and the like. These surtaxes are added directly to the state rate. So a customer in one county might owe a combined rate of 6 percent plus 1 percent (7 percent total), while a customer in an adjacent county might owe 6 percent plus 1.5 percent (7.5 percent total). The combined rate is what you quote, what you charge on the invoice, and what you report and remit to the state.
Because surtax rates can change and vary significantly by county, the safest approach is to check the Florida Department of Revenue website or use their official rate lookup tool whenever you’re unsure of the exact combined rate for a specific county. Many of these tools let you enter the county or ZIP code and immediately see the current rate for that location.
How to file step by step
Filing your sales tax on a Form DR-15 (also called the Florida Sales Tax Return) requires you to report your gross sales and the tax you’ve collected, broken down by taxable category and by county if your business operates or ships to multiple counties.
Start by gathering your transaction records—your sales invoices, point-of-sale reports, and any exemption certificates your customers provided (such as resale certificates). Organize them by county if you do business across multiple counties. For each county, calculate the tax you collected at that county’s combined rate (6 percent state plus the county surtax). The form itself walks you through sections for different product or service categories, so you’ll enter your gross sales in one column and the tax owed in another.
The filing deadline is the 20th of the month following the end of your reporting period (usually monthly for most small businesses, though this can vary). If you miss the deadline, late penalties may apply. When you’re unsure how to categorize a particular sale—whether a service is taxable, for example, or whether a customer qualifies for an exemption—the best practice is to research that specific transaction before you file. The categorization determines the rate and the amount of tax you owe, so getting it right at the outset saves corrections and stress later.
Common mistakes and how to fix them
Mistake 1: Using the state 6 percent rate when a county surtax applies. You’re in Hillsborough County, you charge 6 percent, but Hillsborough has a surtax. You’re undercollecting, which means you’ll owe the shortfall when you file—plus interest. Always confirm the combined rate for the county where your customer is located. If you’ve already undercharged, disclose the discrepancy on your return and remit the full amount due.
Mistake 2: Applying the wrong county’s rate to a sale. You operate in multiple counties, and your point-of-sale system or invoicing doesn’t track which county each customer is in. When you remit, you accidentally apply Broward County’s rate to some Miami-Dade sales. The fix: segment your transactions by county before calculating tax or filing. If your current system doesn’t support this, switch to one that flags the customer location or use a separate invoice for each county’s sales.
Mistake 3: Not understanding what’s taxable. You’re a service provider—a cleaning contractor, a consultant, or a handyman. You assume all your income is taxable and charge 6 percent (or the combined rate) on everything. Florida doesn’t tax most services unless they’re named in Statute 212 (certain construction labor is taxable, for example; others aren’t). You’ve overcollected. The fix: research which of your specific services are taxable. If you’ve overcollected, you may need to refund customers or apply the overage to future invoices.
Mistake 4: Filing late or with incomplete county breakdowns. You remit a single lump-sum tax figure without showing which amount came from which county. The state has no way to verify you applied the right rates in each county, and you risk a notice asking for clarification or a penalty. The fix: always report tax by county on your DR-15 if you operate in multiple counties. Use your transaction data—organized by county—to itemize each one.
Frequently Asked Questions
What’s the difference between the state rate and the county surtax?
The state rate is always 6 percent across all of Florida. The surtax is an additional tax imposed by each individual county, ranging from 0 to 2 percent (or higher in some cases). Together, they make up your combined rate. For example, if your county has a 1.5 percent surtax, you charge and remit 7.5 percent total.
How do I find the exact surtax rate for my county?
Visit the Florida Department of Revenue website and use their tax rate lookup tool or contact their office directly. You can also ask your accountant or check with your county’s tax collector’s office. Once you find it, save it somewhere you reference regularly—a note in your accounting system or a printed chart.
Can I charge whatever tax rate I want as long as I remit the right amount?
No. You must quote and charge the correct combined rate to your customer. If you undercharge and remit the shortfall from your own pocket, you’re absorbing a business cost that the law requires your customer to pay. If you overcharge and keep the excess, you’re violating sales tax law. Always charge the correct rate at the point of sale.
What happens if I file the wrong county rate?
The state may issue a notice asking you to correct the return, remit any underpayment, and pay interest and penalties. If the discrepancy was significant or repeated, it could trigger a more thorough audit. The best defense is to organize your data by county and double-check your rates before you file.
Do I need to report sales tax by county on my DR-15?
If you operate or deliver sales in multiple counties, yes—the form has sections to report tax by county or by region. If all your sales are in a single county, you’ll report only that county’s total. Always follow the current version of the form instructions on the Florida Department of Revenue website.

Getting your county surtax right isn’t glamorous, but it’s foundational. The moment you understand that Florida’s rate is a two-layer system—state plus county—and you make it a habit to verify the combined rate for each location where you do business, the confusion disappears. Many small business owners pair this with their CPA or use a ready-to-review report platform so they can see their categorized transactions and verify the rates before filing. The goal is simple: charge the right amount, file it accurately, and move forward without surprises.
