Does this apply to your business in Florida?
If you sell tangible personal property (physical goods) in Washington County, you almost certainly owe sales tax. If you provide a service, you’re taxable only if that service is specifically listed in Florida Statute 212 — most services are not taxable. The Florida Department of Revenue determines what’s taxable; the state rate is 6%, and your county adds a surtax on top.
How the rate works
Florida sales tax has two parts: the state rate and the county surtax. Every business in Florida pays the 6% state rate. Washington County then adds its own surtax on top of that — the combined rate varies by location, and it changes when counties adjust their local tax ordinances. Rather than guess, check the Florida Department of Revenue website or use their sales tax rate calculator to confirm your exact combined rate. That way you’re filing with the number that’s current for your county today, not a rate from last year.
How to file step by step
Most Florida businesses file the DR-15 form monthly, due by the 20th of the following month. You’ll need to report your total sales (even tax-exempt sales), subtract the tax-exempt portion, and calculate the tax owed on the taxable amount. The form itself guides you through this logic: you enter gross sales, then identify which sales were exempt, then multiply the taxable total by your combined rate (state 6% plus Washington County’s surtax). You can file on the Florida Department of Revenue website or through their online portal. The platform at Outsourcing Processing automatically calculates what’s taxable based on your transaction data, so you’re not doing this math by hand each month — then you can use those figures on your DR-15 and know the numbers are consistent. The exact process of uploading documents and e-filing is walked through step by step here, so you see exactly which screens to click and what each field means.
Common mistakes
Taxing services that aren’t taxable. You might think your service is taxable because you charge for it, but Florida only taxes specific services. If you’re providing labor, consulting, or a service not explicitly named in Statute 212, it’s not taxable. The fix: check Statute 212 or ask the Department of Revenue to confirm your specific service before you start charging tax on invoices you’ve already sent out without it.
Using last year’s combined rate. Surtax rates can shift, and using an outdated rate means you’re either undercharging customers and eating the difference, or overcharging and owing the state money you collected wrongly. The fix: verify your combined rate on the Department of Revenue website before each filing period, not just once at the start of the year.
Missing the DR-15 deadline. If you file after the 20th of the following month, penalties accrue fast. The fix: mark your calendar on the 15th as a reminder to file by the 20th. If you’re using a platform that organizes your transaction data and calculates tax automatically, you’re not scrambling at the last minute to reconstruct sales from bank statements and receipts.
Not keeping resale certificates. If a customer claims they’re reselling your goods and hands you a resale certificate, you don’t tax that sale. If you don’t keep the certificate on file and the state audits you, you’ll owe the tax plus interest. The fix: file resale certificates by customer name and date, either digitally or in a folder you can grab in ten seconds.
Frequently Asked Questions
What’s the difference between the state rate and the county surtax?
Florida imposes a 6% sales tax statewide. Washington County (and every other Florida county) can add an additional surtax for local purposes — roads, schools, emergency services. Your combined rate is state rate plus county surtax. The Department of Revenue’s website shows you the combined rate for your location, so you don’t have to calculate it yourself.
Do I have to collect sales tax if I operate my business from home in Washington County?
Your physical location (home office vs. storefront) doesn’t determine whether you owe sales tax. What matters is what you sell. If you sell tangible goods, you owe tax regardless of whether customers visit you or you deliver. If you provide a non-taxable service, you don’t owe tax whether you work from home or a commercial space. Your business structure and the nature of what you’re selling determine your obligation, not your office address.
Can I deduct sales tax I paid on business purchases from what I owe?
No. Sales tax is a tax on the final consumer, not a cost you can deduct from what you collect. When you buy supplies or inventory for your business and pay sales tax at checkout, that’s your cost of doing business. The tax you owe the state is calculated separately, on the gross sales you collected, minus only those sales that were legitimately tax-exempt (like resales with a resale certificate).
What if I make a mistake on my DR-15 filing?
File an amended return (Form DR-15X) as soon as you notice the error. The sooner you correct it, the less interest accrues. The Department of Revenue’s website explains the amendment process. If you’ve overpaid, you can request a refund; if you’ve underpaid, you’ll owe the difference plus interest, so it’s worth fixing quickly.
How often do I file the DR-15?
Most businesses file monthly, with returns due by the 20th of the following month. Some low-volume businesses may qualify for quarterly filing — check the Department of Revenue’s website or call them to confirm your filing frequency. If you’re unsure, monthly is the safe default; you can request a change after you’ve established your sales pattern.
