You’re sitting at your desk in Orlando or elsewhere in Orange County, watching invoices pile up, and suddenly it hits you: when exactly do you file that sales tax return, and what number goes on the form?

Does this apply to your business in Florida?
The Florida Department of Revenue requires all businesses with sales tax liability in Orange County to file a DR-15 (Sales Tax Return) monthly or quarterly, depending on your filing frequency. If you make sales of taxable goods or services in Orange County—whether you’re selling products to customers, renting equipment, or providing services listed under Florida Statute 212—you’re required to file. Services are generally not taxable unless specifically named in the statute; tangible personal property is taxable unless a specific exemption applies.
How the rate works
Florida’s sales tax is structured as a state base rate plus county surtaxes. The state charges a flat 6% on all taxable sales. Orange County then adds its own surtax on top—the exact county rate changes periodically, so you’ll need to verify the current combined percentage through the Florida Department of Revenue website or their online rate calculator. That combined number (state + county surtax) is what you apply to each taxable sale.
This two-tier system means you’re not guessing at the rate—you look up the current combined percentage for Orange County, apply it consistently, and report it on your return. If you’re selling in multiple counties, each county’s surtax is different, so accuracy matters.
How to file step by step
You’ll file your DR-15 on the Florida Department of Revenue’s online portal, typically through their main website. Here’s the general process:
Step 1: Log in and select the return type. Access your account on floridarevenue.com and choose DR-15 Sales Tax Return. You’ll see options for monthly or quarterly returns, depending on your filing frequency.
Step 2: Enter your sales data. You’ll report total sales (both taxable and non-taxable), calculate tax owed on the taxable portion using the current combined state and county rate, and enter any credits or adjustments you’re entitled to claim.
Step 3: Calculate tax due. The return walks you through the math—total taxable sales multiplied by the combined rate. If you’ve already collected tax from customers, you report what you’ve collected versus what you owe.
Step 4: File and pay. Submit the return and arrange payment by the filing deadline. For monthly filers, the DR-15 is due by the 20th of the following month. Quarterly filers have a different schedule. The Department of Revenue’s website displays your specific due date based on your account settings.
Key timing note: Missing the deadline can result in penalties and interest, so marking your calendar with your due date—or setting a recurring calendar reminder—is your first line of compliance.
Common mistakes
Mixing up what’s taxable. Many business owners assume all services are taxable, or conversely, that all services are exempt. Florida’s rule is the opposite of what you’d guess: services are NOT taxable unless the statute specifically lists them. Professional services, consulting, and labor for installation are often exempt—but repair services and certain labor are taxable. If you’re unsure, check the statute or ask your tax advisor before filing. Filing incorrectly can trigger a notice of discrepancy.
Using last month’s tax rate. Orange County’s combined rate can change when a new surtax ordinance takes effect. If you file with an outdated rate, your calculations will be wrong, even if you did everything else right. Before each return, verify the current combined rate on the Florida Department of Revenue site. It takes 60 seconds and saves headaches.
Forgetting non-taxable sales. The DR-15 asks for total sales, not just taxable sales. Many owners report only the taxable portion and leave the non-taxable line blank. That’s incorrect—you need to show both. The return uses non-taxable sales to calculate compliance, so omitting it creates a red flag for the Department of Revenue.
Losing track of exemption certificates. If a customer claims they’re exempt (resale, non-profit, agriculture), you need a copy of their exemption certificate on file. Without it, you’re liable for the tax, not them. Store these digitally or in a folder by customer, and pull them out when you file—it’s your proof if the Department audits your return.
Frequently Asked Questions
What’s the difference between monthly and quarterly filing?
The Florida Department of Revenue assigns your filing frequency based on your sales volume and history. Monthly filers report every month by the 20th of the following month. Quarterly filers report every three months. Your account on floridarevenue.com shows which one applies to you. If you think your frequency should change, the Department can adjust it.
Do I need a CPA to file the DR-15?
No. The DR-15 is a straightforward return that many business owners file themselves. A CPA can absolutely help—especially if your sales structure is complex or you have multiple locations—but the form itself is designed for you to complete. The role of the Florida Department of Revenue is walked through step by step here. Getting comfortable with the process puts you in control.
What happens if I file late?
Late filing can result in penalties and interest accruing from your original due date. The longer you wait, the larger the bill. If you miss a deadline, file as soon as you notice—the Department typically stops penalty accrual once you file and pay, though interest continues to run. Call the Department if you need guidance on a specific late return.
Can I amend a return I’ve already filed?
Yes. If you discover an error after filing, you can file an amended return on the Florida Department of Revenue portal. The system will recalculate what you owe or are owed as a refund. Keep records of the amendment and the reason for it—this becomes part of your file if you’re ever audited.
What if a customer is tax-exempt?
Resellers, non-profits, and some government entities can claim exemption. You must collect a valid exemption certificate from them before the sale—not after. Store it securely with your records. When you file the DR-15, don’t tax that customer’s purchase. The certificate is your protection if the Department questions why you didn’t charge tax on that transaction.
