If you’re collecting sales tax in Madison County, Florida, you’re likely asking whether everything you sell is taxable. The answer isn’t a simple yes—it depends on what you’re selling and whether it falls under Florida’s tax code. Many small-business owners guess wrong on purpose, pay too much, or underpay without realizing their mistake until the Florida Department of Revenue sends a notice. Getting this right means understanding what tangible property is taxable, which services are exempt, and how county surtaxes stack on top of the state rate. This guide walks you through the rules for Madison County specifically, shows you how the rate is built, and steps through the filing process so you can file your DR-15 return with confidence.

Does this apply to your business in Florida?
Florida taxes tangible personal property—items you can touch—unless a specific exemption applies. Services are generally not taxable unless explicitly listed in Florida Statute 212. The Florida Department of Revenue determines what falls into each category, and the rules are state-wide, though Madison County adds its own surtax on top of the 6% state rate.
How the rate works
Florida’s sales tax structure is straightforward: the state sets a 6% base rate, and each county can add a surtax on top. Madison County residents and businesses pay the state 6% plus the county surtax when they make a taxable purchase. The combined rate varies by county, and it can differ within the same county depending on the tax district. Rather than listing a specific number that may change, confirm the current rate for Madison County through the Florida Department of Revenue website or use their sales tax rate calculator—they update rates regularly as surtax rates change or new districts are created.
When you file your DR-15, you’re reporting the total sales (all transactions, taxable and exempt) and then calculating the tax owed based on the combined state and county rate in effect during the filing month. This means you need to know your county rate before you file, and you should verify it even if you filed last month, because rates do change.
How to file step by step
The DR-15 is Florida’s sales tax return form. You file it by the 20th day of the month following the period you’re reporting. If you sold in January, you file by February 20th. If you haven’t filed yet, our platform organizes your transaction data and walks you through exactly what numbers go where.
First, gather your transaction records for the month. You need total sales, total taxable sales, and any exempt or resale sales. If you use a point-of-sale system or accounting software, these numbers should already be calculated for you—export them or pull a sales report.
Next, log into the Florida Department of Revenue’s online portal (or paper file, though online is faster and more reliable). You’ll enter your business name, Florida sales tax permit number, and the reporting period. Then you’ll input your sales figures: gross sales for the month, the amount that’s taxable, and the amount that’s exempt.
The form then calculates the tax due by multiplying your taxable sales by the combined rate (6% state + Madison County surtax). This is where verifying the exact combined rate matters. If you use the wrong rate, your payment will be off.
Finally, pay the tax due by the deadline. You can pay online, by check, or by electronic funds withdrawal. If you’re filing late or if you know you underpaid a previous month, the Department will inform you of any penalty or interest owed, though we recommend filing on time to avoid additional fees.
Common mistakes
Treating all services as non-taxable. This is the biggest mistake. Most services in Florida are not taxable—a plumber’s labor, an accountant’s fees, a consultant’s hours. But some services are taxable: certain labor on tangible property, pest control, and specific other categories listed in the statute. If you’re unsure whether your service is taxable, check Florida’s Department of Revenue guidance. If you guessed wrong and reported it as exempt when it should have been taxed, you’re liable for the tax plus interest when the Department finds it.
Using an outdated county surtax rate. Madison County’s surtax can change, and new tax districts occasionally overlap the same county. If you file using last year’s rate, your payment will be wrong and you’ll owe the difference plus interest. Always check the current rate before filing, not just once per year.
Mixing personal and business expenses. If you paid for a personal item using your business account, don’t deduct the sales tax paid from your next return. Sales tax is a pass-through tax—you collect it from customers and remit it to the state. You can’t reduce it based on your own purchases. Only wholesale purchases (with a resale certificate) or other specific exemptions reduce your taxable sales.
Forgetting to account for resale certificates. If you’re a reseller or you buy materials to resell or incorporate into a product, you can use a resale certificate to buy tax-free from your supplier. But you only avoid paying tax upstream; you’re still responsible for collecting and remitting tax when you sell to your customer. Many businesses miscalculate because they deduct the resale amount but don’t track the corresponding taxable sale, creating an imbalance on the DR-15.
Frequently Asked Questions
Do I need a sales tax permit to sell in Madison County?
Yes. Florida requires a sales tax permit before you can legally collect sales tax. You apply through the Florida Department of Revenue. Operating without a permit and collecting tax—or collecting without remitting—creates penalties and possible criminal liability.
What’s the deadline to file my DR-15 in Madison County?
File by the 20th of the month following the period you’re reporting. If the 20th falls on a weekend or holiday, the deadline moves to the next business day. Late filing triggers penalties and interest, so set a reminder early in the month.
Can I file DR-15 annually instead of monthly?
Florida allows annual filing only if your average monthly tax liability is less than $150. Most small businesses exceed this and must file monthly. Contact the Florida Department of Revenue to confirm your filing frequency requirement, as it’s based on your historical liability.
Are contractors in Madison County subject to different sales tax rules?
Construction contractors often face complicated rules. Labor on repairs is usually not taxable, but labor on new construction sometimes is. Materials are typically taxable unless you resold them. Every contract is different, so review your specific work with the Florida Department of Revenue or a CPA before assuming an exemption.
What happens if I file late or underpay sales tax?
Late filing triggers a penalty, and underpayment creates interest charges on top of the tax owed. The longer you wait, the more penalty and interest accrue. If the shortfall is large or repeated, the Department may audit prior returns and assess additional liability. Filing on time and accurately is much less expensive than correcting mistakes later.
