Does this apply to your business in Florida?
You must file DR-15 with the Florida Department of Revenue if you’re selling tangible personal property or taxable services in Alachua County. Tangible personal property—physical goods—is taxable unless it falls under a specific exemption. Services, however, are not taxable in Florida unless they’re listed in Statute 212. If you’re a contractor, cleaner, consultant, or professional selling labor or advice, your services are generally not subject to sales tax, but any materials you provide or mark-ups you charge may be. When in doubt, review your revenue: if it includes selling products or renting tangible goods, you almost certainly file DR-15.
How the rate works
Florida’s sales tax is built in two layers: a 6% state rate that applies everywhere in Florida, plus a county surtax that varies by county. Alachua County has its own surtax amount that combines with the state rate to create your total tax obligation. The combined rate you actually apply to a taxable sale depends on the exact rate for Alachua County in the month you’re filing. Since county surtaxes change, always check the current combined rate on the Florida Department of Revenue’s website or use their tax rate calculator to see what applies to your location right now. Writing down “6% + Alachua surtax” is far safer than guessing a combined number—that habit keeps you current as rates shift.
How to file step by step
DR-15 is filed electronically through the Florida Department of Revenue’s online system. You’ll log in, select your filing period (usually monthly for most small businesses), and enter your taxable sales and the tax you’ve collected. The return asks you to report the total sales you made, which sales were taxable under Florida law, and how much sales tax you’ve already collected from your customers. The state compares what you owe against what you’ve paid throughout the month; if you’ve paid more, you may receive a credit or refund; if you owe more, you pay the difference. Filing is due by the 20th of the following month—so January sales get reported by February 20th. This process is walked through step by step in our Florida sales tax basics course if you want a closer look at each screen.
When you file, you’re reporting your combined county and state obligation as one line. The state automatically knows Alachua County’s surtax rate for your filing period, so as long as you report which sales were taxable, the math on your return should match the law. The biggest risk is reporting sales you shouldn’t have—claiming taxable revenue on services or items that are actually exempt. Double-check your revenue before you file.
Common mistakes
Reporting service revenue as taxable. If you’re a lawn care owner, bookkeeper, or contractor, your labor fees are not subject to sales tax. However, if you charge for materials on top of labor, those materials may be taxable. Many small-business owners forget this distinction and report service income on their DR-15, overpaying tax they don’t owe. Before filing, separate your service revenue from any taxable product or material charges. The fix: review your invoice categories or transaction list to pull out pure-service charges, and report only the taxable portion to the Florida Department of Revenue.
Missing the filing deadline. DR-15 is due by the 20th of the following month. Missing that date triggers late-filing penalties and interest that stack up even if your tax bill itself is small. Most owners miss deadlines because the form isn’t in front of them or they forget which month’s sales they’re reporting. The fix: mark the 20th on your calendar the moment your month ends. Better yet, automate it—set a phone reminder or add it to your accounting workflow right now. A two-minute filing is faster than explaining a penalty later.
Not reporting all taxable sales correctly. You might forget cash sales, card transactions from months earlier that haven’t settled, or sales that occurred in Alachua County even though you operate from another county. If your point-of-sale system or transaction data isn’t organized by sale date and location, you risk reporting incomplete revenue. The fix: organize your transaction data before you file. Pull all sales by date and location for the month you’re reporting. If you’re using a system that categorizes and organizes transactions automatically, run a report before filing to make sure nothing’s missing.
Confusing Alachua’s rate with surrounding counties. Alachua County’s surtax is different from Marion, Gilchrist, or Levy County rates. If you serve customers across multiple counties or moved your location, applying the wrong rate means your return won’t match reality. The fix: check the current Alachua County combined rate on the Florida Department of Revenue’s website before every filing. Write it down. Don’t trust your memory or last month’s rate.
Frequently Asked Questions
Do I file DR-15 if I only sell services in Alachua County?
Only if your services are listed as taxable in Statute 212. Most services—consulting, accounting, repairs, labor—are not taxable in Florida. However, if you sell products, rent equipment, or provide taxable services, you file DR-15. Confirm the nature of your revenue with the Florida Department of Revenue or review our Florida sales tax guide to be sure.
What’s the difference between the state rate and Alachua’s surtax?
Florida charges a 6% state rate everywhere. Alachua County adds its own county surtax on top. You report and pay both combined on DR-15—the form doesn’t separate them. The combined rate changes when the county rate changes, which is why you should always verify it on the state’s website before filing.
If I have multiple business locations in different counties, do I file one DR-15 or separate returns?
File one DR-15 per tax account, but break out sales by the county where they occurred. The state’s system knows which county each location is registered in, so report each location’s sales accurately. If you operate under one tax account in one county but have sales in another county, contact the Florida Department of Revenue for guidance on registration and reporting.
What happens if I file late or report the wrong sales amount?
Late filing results in penalties and interest charges on top of your tax bill. Incorrect reporting may trigger an audit or correction notice from the Department of Revenue. The sooner you correct an error, the smaller the interest charge. Contact the Florida Department of Revenue if you’ve filed late or incorrectly; they may work with you on payment plans.
Can I file DR-15 manually or must I use the online system?
Electronic filing is the current standard and fastest way to comply. The Florida Department of Revenue provides the online portal. Paper filing is possible in rare cases but can slow down processing and increase the chance of errors. Use the online system unless you have a documented reason you cannot.
