Does this apply to your business in Florida?
Florida taxes the sale of tangible personal property at the state rate plus a county surtax. Most services are not taxed unless they fall into a specific taxable category listed in Florida Statute 212. If you sell goods or offer services in Calhoun County, you’re required to register for a sales tax permit and file monthly—regardless of whether you’ve made a sale that month.
How the rate works
Florida’s sales tax rate is built in layers. The state charges 6% on all taxable sales. On top of that, Calhoun County adds a local surtax—the exact percentage depends on which district or local option applies in your area. Combined, your customers pay the total rate on eligible purchases.
The key is that the state and county rates stack. You don’t apply them separately and keep the difference; you collect the combined rate, then remit the state portion to the Florida Department of Revenue and the local portion to the county. For Calhoun County’s specific surtax amount, check the Florida Department of Revenue website or use their sales tax calculator to see the combined rate for your location. Rates can change, so verifying the current figure before you file is a habit worth building.
How to file step by step
Filing your DR-15 (the state’s sales tax return) is the core monthly task. Here’s what the process looks like:
1. Gather your transaction records. Before you log in to file, have your sales records organized by category. Separate taxable sales (tangible goods and qualifying services) from non-taxable sales (most services, exempt resales, or items purchased with a resale certificate). If you’re running a business in Calhoun County, you need to track what was sold, when, and whether tax applied.
2. Calculate taxable and exempt totals. Add up all sales that are subject to the state 6% and the county surtax. Keep exempt sales separate—they reduce your taxable base but still appear on your return. This is where a category system becomes invaluable; each month, you’ll know exactly which transactions belong in the taxable or exempt bucket.
3. Enter the DR-15 on the Florida Department of Revenue website. You can file online through their portal. Enter your permit number, the reporting period (usually the first through the last day of the previous month), your total taxable sales, any exempt sales, and other applicable lines. The form also asks for tax collected—multiply your taxable sales by the combined state and county rate to get that number.
4. Calculate tax owed (or a refund). Compare what you collected from customers to what you owe to the state and county. If you’ve overwithheld (collected too much), you may be entitled to a refund. If you under-collected, you owe the difference. The DR-15 will show this calculation once you fill in the amounts.
5. File by the 20th of the following month. The deadline is consistent: sales from January are reported by February 20th, sales from February by March 20th, and so on. Filing late can trigger penalties and interest, so this date is non-negotiable. Mark it in your calendar or set a reminder—even one day late starts the clock on late-filing consequences.
6. Pay any tax owed electronically. The state accepts credit card, bank transfer, and other electronic methods. Include your permit number in the payment reference so it’s applied correctly. Keep a record of the payment confirmation; you’ll want it for your records if questions ever arise.
The entire process—gathering records, calculating, filing, and paying—works smoothly when your sales are categorized consistently throughout the month. Many businesses find that organizing transactions as they happen, rather than scrambling to sort them the day before the deadline, cuts filing time in half.
Common mistakes
Mixing services and sales without a clear rule. A cleaning company in Calhoun County might think cleaning services are tax-exempt (because most services are), then later learn that janitorial supplies passed through to the customer count as taxable sales. The fix: check the Florida Department of Revenue for your specific service type, or ask your CPA before you assume. When in doubt, test the categorization on a small filing and adjust if needed.
Forgetting to account for resale certificates. You sell products to another business that resells them. If you didn’t collect the resale certificate before the sale, you’ll owe tax on that transaction—even though it wasn’t a final retail sale. The fix: always request and keep a signed resale certificate on file before you exempt a transaction. Spot-check your records quarterly to make sure you have certificates for every resale claim you’re making.
Filing late or missing the deadline. One month you’re busy, the deadline slips your mind, and now you’ve triggered late-filing interest and potential penalties. The fix: set a phone reminder or a calendar alert for the 15th of each month—five days before the 20th deadline. This gives you a buffer to gather records and file without rushing.
Using the wrong combined rate. Calhoun County’s surtax changes occasionally, or you use an outdated rate from last year. You collect too little, and when you file, you’re short on tax owed. The fix: before each filing period, confirm the current combined state and county rate on the Florida Department of Revenue website. It’s a 30-second check that prevents a mismatch.
Frequently Asked Questions
Is my service taxable in Florida?
Most services are not taxable unless they’re specifically listed in Florida Statute 212. Common taxable services include pest control, repair and maintenance of tangible property, and janitorial services. Non-taxable services include accounting, consulting, and many digital services. Check the Florida Department of Revenue for a list of taxable services, or ask your CPA if your specific service falls into a gray area.
What’s the difference between state and county tax on the DR-15?
The DR-15 shows your total taxable sales and the total tax you collected. The state’s 6% portion goes to the Department of Revenue; the county surtax portion goes to Calhoun County. When you file, you’re reporting both, but the system routes the payments to the correct agency. You don’t have to split the money yourself—the filing and payment process handles that.
Do I have to file a DR-15 every month, even if I had no sales?
Yes. Once you register for a sales tax permit in Florida, you’re required to file every month. If you had no sales or only non-taxable sales, you’ll file a return showing zero tax due. Missing a filing, even for a zero-sales month, can result in penalties, so staying on schedule is essential.
Can I claim a tax refund if I overcollected?
If you collected more tax from customers than you owe to the state and county, the DR-15 will show a credit or refund due to you. Some businesses carry the credit forward to offset the next month’s tax owed. Others request a refund check. Both are allowed, but verify the current procedure on the Florida Department of Revenue site.
What happens if I file late?
Late filing can result in penalties and interest accruing daily on any tax owed. The longer the delay, the larger the accrual. Filing by the 20th of the following month is the safest approach to avoid these costs. If you’ve missed a deadline, file as soon as possible to minimize further accrual.
