You file your Florida sales tax return because the state requires you to account for the sales tax you’ve collected from customers—but the process can feel murky if you’re not sure which sales are taxable, where to find your county’s surtax rate, or how the DR-15 form itself actually works. If you own a small business in Florida, filing your sales tax return correctly and on time is a core compliance habit, but the details trip up many first-time filers and even experienced business owners who haven’t filed in a while. This guide walks you through the DR-15 form step by step, explains the tax structure Florida uses, and covers the mistakes that cost time and credibility with the state.

Does this apply to your business in Florida?
You must file a Florida sales tax return if you collected sales tax from customers or your business type triggers a filing requirement—that is, you sold tangible personal property that is not exempt from tax, or you provided a service listed as taxable under Florida Statute 212. The Florida Department of Revenue sets the rules: tangible personal property is taxable unless specifically exempted by law; services are generally not taxable unless explicitly listed as taxable in the statute. If you’re unsure whether your business activity requires filing, the Department of Revenue website has detailed guidance by industry.
How the rate works
Florida’s sales tax is structured as a base state rate plus a county surtax. The state imposes a 6% sales tax on all taxable sales. On top of that, your county adds its own surtax—a discretionary local rate that varies by county. This combined rate (state plus county) is what you collect from customers and report on your return. Because the county rate changes periodically and differs across the state, you should always check the current combined rate for your county on the Florida Department of Revenue website or use their rate calculator to confirm the exact percentage you owe before you file. Recording the right rate from the start prevents rework and reconciliation headaches later.
How to file step by step
The DR-15 is the standard monthly sales tax return form in Florida. Filing happens online through the Department of Revenue portal, and you’ll need your Federal Employer Identification Number (EIN) and a login for the system.
Step 1: Gather your transaction data. Before you open the form, organize your sales records—both taxable sales (tangible goods and any taxable services listed in Statute 212) and non-taxable sales (like certain services). You’ll also need a record of any sales tax you collected, any refunds or credits you issued, and any tax payments you’ve already made this year. Many businesses track this in their accounting system or bank records.
Step 2: Log in and enter your reporting period. Access the Department of Revenue’s online filing system and select your business account. Enter the month and year for which you’re filing. Florida requires monthly returns for most businesses, due by the 20th of the following month. Confirm the period matches your records before proceeding.
Step 3: Report your gross sales. The form asks for your total gross sales—all revenue from sales of tangible personal property and taxable services for the period, before you deduct any tax. Do not subtract the sales tax you collected; report the pre-tax amount. This is where accuracy in your bookkeeping shows. If you’ve used an accounting system or Outsourcing Processing to organize and categorize your transactions, you can pull this figure from your sales report.
Step 4: Report your non-taxable sales. Many businesses have some revenue that isn’t subject to sales tax. This section asks you to report that separately. Examples might include certain exempt services or sales to tax-exempt entities. Correctly separating taxable from non-taxable sales is critical—it ensures your net taxable sales (the amount you multiply by the tax rate) is correct. This is also where the industry rule applies: if you’re a service provider, only include services that are specifically listed as taxable in Florida Statute 212.
Step 5: Calculate and report tax due. The form will show your net taxable sales (gross sales minus non-taxable sales). Multiply that by the combined rate for your county to calculate the tax due. If you used the state’s rate calculator or stepped through the rate structure with a guide, you’ll have the exact percentage. Enter the total tax owed in the designated field.
Step 6: Account for payments and credits. Report any sales tax payments you’ve already made during the period (if you pay weekly or more frequently) and any credits or refunds you’ve issued. Subtract these from the tax due to arrive at the net amount owed or the refund due to you.
Step 7: Review and submit. Double-check each figure, especially your gross sales, non-taxable sales, and tax rate. A small math error can create confusion with the Department of Revenue. Submit the return before the 20th of the following month. Keep a copy of your confirmation for your records.
Common mistakes
Mistake 1: Using the wrong county tax rate. If you operate in multiple counties or recently relocated, applying the wrong surtax rate to your sales will throw off your entire return. You collect the wrong amount from customers, and when you file, the state sees a mismatch. The fix: confirm your county’s current combined rate on the Department of Revenue website or calculator at the start of your reporting period, and update your records if the rate changed mid-month.
Mistake 2: Including non-taxable revenue as taxable sales. Some service businesses mistakenly add all their revenue as gross sales. Under Florida law, services are generally exempt unless Statute 212 specifically lists them as taxable. If you’re a consultant, bookkeeper, or contractor offering services not on the taxable list, that revenue doesn’t count as taxable sales. The fix: review Statute 212 or ask your CPA which services you provide are taxable. Separate those into the taxable line and everything else into the non-taxable line.
Mistake 3: Forgetting to report sales tax you already paid to suppliers. If you purchased taxable inventory during the period and paid sales tax to your supplier, you may be eligible to claim that as a credit on your return—this is called taking a resale exemption or claiming an input tax credit, depending on your situation. Forgetting to include it means you overpay tax. The fix: keep copies of all invoices showing sales tax paid, and ask your CPA whether you qualify for the credit. This gets walked through step by step here in the Florida sales tax basics course.
Mistake 4: Missing the filing deadline. The DR-15 is due by the 20th of the following month. Missing this date can trigger late-filing notices or additional compliance costs. The fix: set a calendar reminder on the 15th of each month to file, or schedule your return filing as part of your monthly compliance routine. If you have a CPA or use outsourced help, confirm they know your deadline.
Frequently Asked Questions
What is the difference between gross sales and taxable sales on the DR-15?
Gross sales include all revenue from your business for the period, both taxable and non-taxable. Taxable sales are the portion of gross sales subject to Florida’s 6% state rate plus your county surtax. You report gross sales, then subtract non-taxable sales to get net taxable sales, which is the amount you multiply by the combined rate to calculate tax due.
Do I need to file a DR-15 if I didn’t collect any sales tax?
Even if you had no taxable sales or collected zero tax, you may still be required to file a “zero return”—a blank or $0 return—if the state has you registered for sales tax. Contact the Florida Department of Revenue to confirm your filing requirement, as some low-revenue or exempt businesses may be excused from filing.
What happens if I miss the filing deadline?
Missing the 20th-of-the-month deadline can result in late-filing notices, penalties, and additional costs to your business. The Department of Revenue may assess late fees and require interest on unpaid tax. The best approach is to file early and keep proof of your submission; if you need an extension, contact the Department of Revenue directly.
Can I file the DR-15 on paper, or must it be filed online?
Florida requires most businesses to file the DR-15 electronically through the Department of Revenue’s online system. Paper filing is available in limited cases, typically for businesses with genuine hardship or those registered before a certain date. Check the Department of Revenue website to confirm your business’s filing method.
What if my county’s surtax rate changed in the middle of my reporting period?
If your county’s surtax rate changed during the month, you calculate tax due by applying the rate that was in effect for sales made on each date. You’ll report sales made under the old rate and sales made under the new rate separately, then calculate tax on each group. This is complex, so consult your CPA or the Department of Revenue for guidance on your specific situation.

Filing your Florida sales tax return on time and correctly is a habit that compounds: each month you file accurately, you build confidence and keep your business’s relationship with the state clean. Your records become your proof. If you’re managing this yourself, track your sales, verify your county’s current tax rate, and set a monthly reminder for the 20th. If your bookkeeping is not yet organized, consider how a platform like Outsourcing Processing’s Florida sales tax guide can help you categorize transactions automatically, so your taxable sales are ready to report each month.
