If you own a business in Marion County—whether you’re selling products, providing services, or both—you face one unavoidable responsibility: filing the DR-15 each month. That form doesn’t file itself, and missing a deadline or miscalculating your county surtax can cost you money in penalties and interest you never saw coming. You’re juggling inventory, staffing, and sales; the last thing you need is a surprise notice from the Florida Department of Revenue. The good news is that Marion County’s sales tax structure is straightforward once you understand how the state rate and county surtax work together, and once you know exactly what’s taxable under Florida law. This guide walks you through the real filing process, shows you the most common mistakes, and gives you the confidence to handle your DR-15 without guessing.
Does this sound like you? You’re running a Florida business and don’t have time to become a tax expert too. If a permit, an exemption rule, or the DR-15 has you stuck, see how the platform keeps this organized — your first period is free for a limited time, every tool unlocked, no credit card.
Does this apply to your business in Florida?
Yes, if you operate a business in Marion County and collect sales tax. The Florida Department of Revenue requires any retailer (selling tangible personal property) or service provider (if your service is specifically listed as taxable in Florida Statute 212) to register for a sales tax permit and file the DR-15 each month. Services are generally not taxable in Florida unless explicitly listed in statute—so a plumber or consultant typically doesn’t collect sales tax, but a product retailer always does.
How the rate works
Florida charges a base state sales tax rate of 6%, and Marion County adds its own surtax on top of that. The combined rate (state plus county) is what you apply to each taxable transaction. Don’t try to memorize or guess the exact combined percentage for Marion County—rates change, and you need accuracy. Visit floridarevenue.com or use their rate lookup tool to confirm the current combined rate before you file. The structure is always the same: every dollar of taxable sales gets hit with both the state 6% and the county surtax, calculated automatically when you use the correct rate.
How to file step by step
The DR-15 is filed online through the Florida Department of Revenue’s online system. Here’s the process: First, log in to your sales tax account using your Florida sales tax permit number. You’ll see a prompt to file a return for the current month. The return period follows the calendar month—you file by the 20th of the month following the sales period. For example, sales made in January are reported on a return due by February 20th.
Once you’re in the return, you’ll enter your total sales for the period, then break down which sales are taxable and which are exempt. This is where knowing Florida’s taxability rules matters. You’ll apply the combined rate (6% state plus Marion County surtax) to your taxable sales. The system calculates the tax due. If you’ve made prepayments or overpaid in a prior month, you can apply those credits. Review the amount due, and submit. If tax is owed, you pay online or by mail according to the due date. If you’re due a refund, the Department processes it.
Keep a record of your submission confirmation. The Department may ask for supporting documentation—sales records, exemption certificates, transaction logs—so don’t discard anything until you’re sure the return is accepted and the period is closed. If you use accounting software or a bookkeeping platform, you can often generate reports that feed into the DR-15, making this step faster and less error-prone.
Common mistakes
Mistake 1: Mixing up taxable and exempt sales. The biggest trap is claiming a sale is exempt when it isn’t, or vice versa. Imagine you provide consulting services and also sell training materials. The consulting advice isn’t taxable; the printed material is. If you lump them together and apply the wrong rate, you’ll either owe more tax plus interest, or claim a false exemption and trigger an audit. Fix: Know Florida’s taxability rules for your specific business type. If you’re unsure whether a sale is taxable, check with the Department or a CPA before filing, not after.
Mistake 2: Forgetting the county surtax exists. A business owner in Marion County who only applies the state 6% rate is leaving county tax uncollected—or paying it themselves. This creates a shortfall on your DR-15 and can trigger a follow-up assessment. Fix: Always use the full combined rate (state plus county). Verify the exact combined percentage on the Florida Department of Revenue website before you report each month.
Mistake 3: Missing the filing deadline. The DR-15 is due by the 20th of the month after your sales period ends. If you file on the 21st, you’ve missed the deadline. Late filings accrue penalties. Fix: Mark your calendar on the 15th of each month as a reminder. If you use accounting software, set up an automated alert. Filing three days early gives you a buffer for technical issues or unexpected questions.
Mistake 4: Not keeping exemption certificates on file. If a customer claims they don’t owe sales tax (because they have a resale certificate, for example), you need to keep that proof. Without it, the Department will hold you liable for the tax, even if the customer was the one who should have paid. Fix: Collect resale certificates, exemption documentation, and customer details before the sale. Store them digitally or in a folder by customer, organized by month.
Frequently Asked Questions
What’s the deadline for the DR-15 in Marion County?
The DR-15 is due by the 20th of the month following your sales period. So sales made in January must be reported by February 20th. If the 20th falls on a weekend or holiday, the deadline shifts to the next business day. Check the Florida Department of Revenue website for the exact calendar each year.
Do I need to pay sales tax on services in Marion County?
Not all services are taxable in Florida. Services are taxable only if they’re specifically listed in Florida Statute 212. For example, repair services, certain professional services, and some specialty work may be taxable; general consulting typically isn’t. Review your specific service type with the Department or a CPA to confirm whether you collect tax on your work.
What happens if I file the DR-15 late?
Late filing can result in penalties and interest assessed on the tax due. The longer the delay, the higher the cost. Even one day late counts as late. If you’re unable to file by the deadline, contact the Florida Department of Revenue as soon as possible to discuss your options—sometimes they can grant relief under specific circumstances.
Can I file the DR-15 on paper, or is it online only?
The Florida Department of Revenue requires online filing for most businesses. Paper filing is only available in limited circumstances, typically for very small businesses or those with specific hardships. Check the Department website or call to see if you qualify. Online filing is faster and leaves an automatic timestamp, so it’s the safest option if you’re able.
What if I collected sales tax but didn’t file the DR-15?
You’re liable for the tax whether you filed or not. The Department will eventually discover the missing returns through other records, assess the tax owed plus penalties and interest, and send you a bill. It’s far cheaper and faster to file late than to wait and face an enforcement action. If you’ve missed months, file those returns immediately and reach out to the Department to explain and discuss payment options.

Your Marion County sales tax filing starts with the right foundation
The DR-15 isn’t complicated, but it does demand accuracy. You need to know what you’re selling, whether it’s taxable under Florida law, and what rate applies in your county. Once you have those three things clear, the filing process becomes routine. Set a monthly habit: pull your sales records, categorize them correctly, apply the combined rate, and file by the 20th. If you’re carrying transaction data in your head or a disorganized spreadsheet, consider using a bookkeeping platform that automates transaction categorization and sales tax calculation—it turns filing from a stressful guessing game into a straightforward review. Over time, that consistency builds confidence and keeps you clear of surprises.
