Does this apply to your business in Florida?
Florida sales tax applies to the sale of tangible personal property—physical goods—unless a specific exemption exists. Services are not taxable under Florida law unless they are specifically listed in Florida Statute 212. For example, if you sell products, you collect and remit sales tax. If you provide a service—like consulting, repairs, or labor—you generally do not, unless that service is explicitly taxable. The Florida Department of Revenue sets the baseline rule and exemptions; your county may add a surtax on top of the state rate.
How the rate works
Florida’s sales tax has two layers: a 6% state rate and a county surtax. DeSoto County applies its own local surtax on top of the state rate, and the combined total is what you charge customers and later remit to the state. The exact combined rate varies by county and can change, so instead of stating a specific number here—which could be outdated—you should verify the current rate directly on floridarevenue.com or by contacting the Department of Revenue. This ensures you’re always using the most current figure when you set up your register or calculate liability on your DR-15.
Think of it this way: the state takes its cut first, and then the county takes its cut, but you collect and remit the total in one payment. Understanding that structure helps you see why the rate you charge differs from the rate your neighbor in another county charges.
How to file step by step
Filing your sales tax in Florida means completing the DR-15 form (or its electronic equivalent) and submitting it to the Department of Revenue by the 20th of the month following the period you’re reporting. Most businesses file monthly, though the state may allow quarterly or annual filing in certain circumstances.
Here’s the process:
- Gather your sales records for the reporting period (usually one month).
- Add up all taxable sales—the goods subject to sales tax.
- Subtract any exempt sales or returns.
- Multiply the result by the combined rate (6% state + DeSoto County surtax) to calculate tax due.
- Report this on your DR-15 form, either on paper or online through the Department of Revenue portal.
The key is accuracy: if your records show $10,000 in taxable sales and you miscalculate the tax owed, the error compounds over time. Recording which sales are taxable and which are exempt—at the point of sale—makes filing much easier. The role of the Florida Department of Revenue and how to use their resources is walked through step by step here, so you understand where to get forms, track deadlines, and verify rates.
Payment is due by the same deadline. The state offers electronic filing and payment options that reduce paperwork and give you a record of submission. If you miss the deadline, penalties and interest begin to accrue, so setting a calendar reminder for the 20th of each month is worth the thirty seconds it takes.
Common mistakes
Mistake 1: Treating all services as non-taxable. While most services are not taxable, some are. For instance, certain repairs, installations, or labor bundled with a product sale may trigger tax. If you’re unsure whether your service is taxable, look it up on the Department of Revenue website or ask in writing—don’t guess. The fix is to confirm the taxability of what you sell before you start charging customers, so you’re compliant from day one.
Mistake 2: Mixing exempt and taxable sales without tracking them separately. You might sell both taxable products and exempt services, or sell to both retail customers and tax-exempt entities like nonprofits. If you don’t track which transaction falls into which category, your DR-15 filing will be incorrect. The fix is to use a register or bookkeeping method that tags each sale as taxable or exempt at the time of sale. This takes a few extra seconds per transaction but saves you hours of guesswork when you file.
Mistake 3: Forgetting about the county surtax. New businesses sometimes use only the 6% state rate when calculating their liability, forgetting that DeSoto County adds more on top. This means they under-remit to the state every month and build up a shortfall that’s hard to catch until an audit surfaces it. The fix is simple: confirm the combined rate for your county now, write it down, and use it in every calculation until you verify it has changed.
Mistake 4: Filing late or not filing at all. If you owe sales tax and don’t file by the 20th, penalties and interest start accruing. Some business owners think that if they collected the tax but didn’t remit it, they’re “good”—they’re not. The state’s concern is remittance, not collection. The fix is to treat your DR-15 deadline like any other non-negotiable business date—in your calendar, on your checklist, no exceptions.
Frequently Asked Questions
Q: Do I have to collect sales tax on every sale?
A: No. Only taxable transactions require sales tax. If you sell tangible personal property, yes. If you provide a service not listed as taxable in Florida Statute 212, no. If you’re unsure what you sell, check with the Department of Revenue or a tax advisor. Exemptions exist for certain products and entities, and misclassifying a sale is a common error.
Q: What’s the deadline for filing DR-15 in DeSoto County?
A: The deadline is the 20th of the month following the reporting period. For most businesses, that’s the 20th of each month. If the 20th falls on a weekend or holiday, the deadline moves to the next business day. Mark these deadlines in your calendar now to avoid late-filing penalties.
Q: Can I file and pay sales tax online?
A: Yes. The Florida Department of Revenue offers an online portal where you can file your DR-15 and make payments electronically. Online filing is often faster, cleaner, and gives you an instant confirmation—it’s worth the switch if you’re still filing by paper.
Q: What happens if I file late or file the wrong amount?
A: Late filing triggers penalties and interest. Filing the wrong amount (under or over) means you’ll owe the difference plus penalties in the case of underpayment. If you discover an error after filing, you can file an amended return. The key is to fix errors as soon as you spot them rather than hope they go unnoticed.
Q: Does DeSoto County have a different rate than other Florida counties?
A: Yes. Each Florida county sets its own surtax, so DeSoto’s combined rate differs from Miami-Dade, Broward, or other counties. Always use the rate that applies to your location and the location where your customer is located (for remote sales, this gets more complex). Verify the current rate on floridarevenue.com or your Department of Revenue notice.
