You’re running a business in Sumter County, and sales tax compliance sits somewhere between confusing and terrifying. You’ve heard about the DR-15 form, county surtaxes, and exemptions—but nobody explains exactly how they work together or what you actually owe each month. That gap between knowing you should file and knowing how creates stress, potential penalties, and the sinking feeling that you’re missing something obvious. This guide walks you through the real mechanics: the state rate plus your county surtax, how the DR-15 actually works, where most Sumter County business owners get tripped up, and how to build a filing system that doesn’t depend on an expensive CPA’s calendar.

Does this apply to your business in Florida?
Florida requires you to collect and remit sales tax on tangible personal property and certain enumerated services. The Florida Department of Revenue taxes personal property sales unless a specific exemption applies; most services are not taxed unless they’re listed in Florida Statute 212. If you sell products or provide taxable services, you need a sales tax permit and must file the DR-15 form monthly by the 20th of the following month.
How the rate works
Florida’s sales tax structure combines two layers: a statewide rate of 6% plus a county surtax that varies by location. Sumter County residents and businesses pay whichever surtax applies in that county. The total rate you charge depends on your location and your customer’s location—if you’re in Sumter County, you’ll apply Sumter’s surtax to your sales. The combined percentage changes if the county adjusts its surtax, which is rare but possible. Rather than guess at the current combined rate, visit floridarevenue.com to confirm the exact percentage for your county, or use their sales tax rate calculator to verify before filing.
How to file step by step
Filing the DR-15 happens on floridarevenue.com through the department’s online portal. First, log into your account or register your business with your sales tax permit number and authorization code. You’ll land on a dashboard showing your filing periods—Sumter County businesses on monthly filing are due by the 20th of the following month (so February sales file by March 20th). Click your open period and you’ll see a summary screen with a blank form. Here’s the step-by-step flow: enter your gross sales for the period in the designated field, then enter any sales that are taxable. The system calculates tax owed based on your county’s combined rate. Next, enter any tax collected from customers and any tax you paid on wholesale purchases (a credit you can claim back). Review the totals. If you owe money, the portal shows the amount due and offers a payment method—most businesses pay online directly from a bank account. Submit the form, and you’ll receive a confirmation number. Save this confirmation; it proves filing in case of any audit question. The deadline is the 20th of the following month, and most businesses file on the 15th to avoid last-minute scrambling.
Common mistakes
Mistake 1: Mixing personal and business sales. You charge sales tax only on business sales to customers. If you accidentally mix in personal items or incorrectly apply tax to untaxable services, your filing number doesn’t match your actual receipts. Fix: separate your business and personal transactions from day one. Categorize each transaction as taxable or non-taxable before you reconcile for the month.
Mistake 2: Forgetting county surtax exemptions. Certain items or activities are exempt from county surtax even if they’re subject to the state rate, and some counties have their own local exemption rules. A contractor or reseller who doesn’t know these exemptions pays surtax on purchases that shouldn’t be taxed. Fix: check the Florida Department of Revenue site for Sumter County surtax exemptions and review your purchases quarterly. If you resell goods, use a resale certificate to avoid tax on wholesale stock.
Mistake 3: Late filing or missing a period. Filing late triggers a failure-to-file penalty, even if you owe zero dollars. Skipping a month entirely is worse—the department flags it as a missing return. Fix: mark the 20th of every month on your calendar and file even if you had zero sales (you still file a return showing $0). Many business owners set a phone reminder on the 15th to give themselves a five-day buffer.
Mistake 4: Not tracking receipts to match filings. You report gross sales on the DR-15, but your actual receipts should match that number. If they don’t and an audit happens, you’ll have trouble explaining the difference. Fix: keep a simple monthly total of all receipts—sales journal, point-of-sale report, or even a spreadsheet. File it alongside your DR-15 confirmation so you have proof if the department asks questions later.
Frequently Asked Questions
What’s the difference between the state rate and the county surtax?
Florida’s state rate is 6%, which applies statewide. A county surtax is an additional local tax that Sumter County (and other counties) may add to fund county services. Your customer pays both—the combined rate is what you charge at the register. The Florida Department of Revenue shows both rates on their website.
Do I have to file a DR-15 if I have zero sales?
Yes. Even if you earned no revenue in a month, you must file a return showing $0. Filing zero returns keeps your account current and avoids penalties. If you skip filing because you had no sales, the department treats it as a missing return, which can trigger a late-filing penalty.
What’s the deadline for the DR-15?
The DR-15 is due by the 20th of the month following your sales period. Sales in February are filed by March 20th. If the 20th falls on a weekend or holiday, check floridarevenue.com for the adjusted deadline that month. Filing online extends your deadline slightly; confirm the exact date on the portal.
Can I deduct my business expenses from sales tax?
No. Sales tax is calculated on your total sales, not your profit. You don’t reduce your tax obligation by subtracting expenses or cost of goods sold. Sales tax is a pass-through tax—you collect it from customers and remit it to the state. If you’re owed a refund (for example, overpaid tax or returned goods), you claim that on your DR-15 return, not a separate refund form.
What happens if I file late?
Late filing triggers penalties. The amount varies, but the Florida Department of Revenue starts assessing penalties immediately after the 20th deadline passes. The longer you wait, the higher the penalty. The best strategy is to file on time, even if you owe money and can’t pay immediately—filing late and owing is worse than filing on time and requesting a payment plan.
