You’re running a business in Hamilton County, and every month you wonder if you’re charging sales tax on the right things—and collecting it correctly. Whether you sell products, offer services, or both, Florida’s sales tax rules can create confusion, especially when you’re bootstrapped and trying to keep costs down. The state rate is straightforward, but each county adds its own surtax, and the rules about what’s taxable shift depending on what you sell. Getting it wrong costs you: uncollected tax liability, filing errors, and the back-and-forth with the Florida Department of Revenue. You need clear rules, not guessing.

Does this apply to your business in Florida?
If you sell tangible personal property in Hamilton County, sales tax applies. Florida exempts most services from tax unless they’re explicitly listed in Statute 212—meaning your service business likely doesn’t owe sales tax on labor, but a product reseller always does. The Florida Department of Revenue enforces these rules uniformly across the state, but each county adds a surtax on top of the 6% state rate.
How the rate works
Florida’s sales tax structure combines a state rate and a county surtax. The state charges 6% on all taxable transactions. Hamilton County then adds its own surtax on top of that. The combined rate—state plus county—varies, so the total you collect depends on your location within the county. Rather than guessing at the exact combined percentage, use the Florida Department of Revenue tax rate lookup tool or a sales tax calculator to find the current combined rate for your specific address. Tax rates can change, and the calculator always reflects what’s current.
How to file step by step
You file sales tax in Florida using Form DR-15, the monthly sales tax return. Here’s how the process works on the Florida Department of Revenue website.
First, gather your transaction data for the filing month. You need total sales (including taxable and non-taxable sales, because the form asks for both). If you use a point-of-sale system or accounting software, pull a sales summary showing the breakdown. The role of the Florida Department of Revenue and how filing works is walked through step by step here.
Second, log into the Florida Department of Revenue’s online filing system (called EFTPS or the DOR portal, depending on your filing preference). You’ll enter your sales figures and the tax you collected. The form breaks down taxable sales and tax due by rate, which means if you have multiple locations or a mix of taxable and non-taxable sales, you’ll enter them separately.
Third, calculate the tax due. This is where many owners make mistakes: you multiply your taxable sales by the combined rate (6% state plus the county surtax for Hamilton County). If you’ve collected that amount from customers, you simply report it. If you haven’t collected enough, you still owe the difference. If you’ve over-collected, you get a credit.
Fourth, submit the return by the 20th of the month following the reporting month. If you owe tax, you also remit payment at the same time. The Florida Department of Revenue accepts electronic payments, checks, or credit card payments, depending on your setup.
Finally, keep records. The state requires you to retain sales records for five years. That means your invoices, receipts, point-of-sale reports, and any exemption certificates from customers should be filed and accessible. If you’re unsure whether a transaction was taxable, your records are what prove you collected or didn’t collect tax correctly.
Common mistakes
Mistake 1: Assuming all services are tax-free. Many service providers think they never owe sales tax. That’s wrong if your service is listed in Statute 212 as taxable—for example, certain labor-intensive services tied to tangible property may be taxable in specific circumstances. The safest move: if you’re uncertain whether your service is taxable, contact the Florida Department of Revenue or consult a CPA before you start collecting. Fixing this later is expensive.
Mistake 2: Using the wrong tax rate. You look up the Hamilton County surtax once and hard-code it into your system. Then the surtax changes (unlikely but possible) or your business moves to a different county, and you’re still charging the old rate. Each month, confirm the combined rate is current by checking the official calculator. If you use accounting software, keep the tax tables updated.
Mistake 3: Not tracking exemptions properly. You sell to a wholesale customer or a tax-exempt organization and skip collecting tax. But you didn’t collect a signed exemption certificate. Later, the state asks where the exemption documentation is, and you can’t produce it. Always collect and file exemption certificates in the same organized way you file receipts.
Mistake 4: Mixing personal and business sales. You occasionally sell items from your inventory personally, or vice versa—mixing the two in your records and then reporting it all as business sales tax. This creates a mismatch between your reported tax and your actual taxable sales, which triggers audits. Keep personal and business sales separate from the start, even if they’re small.
Frequently Asked Questions
What counts as taxable in Hamilton County?
Tangible personal property is taxable unless specifically exempt. Services are generally not taxable unless listed in Florida Statute 212. Examples: a plumber’s labor is usually not taxable, but the materials they install are. A cleaning company’s service is not taxable, but supplies they sell are. Always confirm your specific offering with the Florida Department of Revenue or your CPA.
When is my sales tax due in Hamilton County?
Sales tax is due by the 20th of the month following the month in which you made the sales. For example, sales made in January are reported and paid by February 20th. If the 20th falls on a weekend or holiday, the deadline extends to the next business day. File on time to avoid penalties.
Can I file sales tax myself, or do I need an accountant?
You can file DR-15 yourself if you organize your sales data and have access to the Florida Department of Revenue portal. Many owners prefer to do this to keep costs down and maintain control. Others hire a CPA or bookkeeper. Either way, having clean, organized transaction records makes the process faster and less error-prone. Our platform helps you organize and categorize your transaction data so you’re ready to file or hand off to your CPA with confidence.
What if I collected more sales tax than I owe?
If you over-collected, the Florida Department of Revenue issues you a credit. You can apply that credit to future months’ tax due, or request a refund (though refunds can take time). Report the over-collection on your DR-15 form, and the state will handle it. Always report the actual tax collected, even if it’s more than you owe.
Do I need to file if I had no sales?
Many counties require a “zero return” even if you made no taxable sales. File a return showing zero sales and zero tax due. Skipping the filing, even for zero months, can result in penalties. Check your registration letter from the Florida Department of Revenue to confirm whether you must file monthly, and if so, whether zero returns are required.
