You manage dozens of clients across different industries, counties, and filing schedules. Each one owes Florida sales tax on something different—one’s selling tangible goods, another’s filing a service exemption, a third is stuck between a surtax boundary and a rate change. You’re tracking DR-15 deadlines, county-specific rules, and exemption certificates manually. One missed filing or miscategorized transaction ripples across your practice as a client complaint or a regulatory follow-up. The friction point isn’t understanding the rules—it’s scaling compliance across a fragmented client base without hiring extra staff. If you’re a CPA supporting small Florida businesses, you need a system that organizes transaction data, applies the right tax logic to each client’s situation, and surfaces what matters before you review it.
Does this sound like you? Clients hand you a shoebox of receipts every quarter. See how the platform gives you clean, categorized reports before they land on your desk — your first client’s first period is completely free, every tool unlocked.
Does this apply to your business in Florida?
Florida applies a 6% state sales tax on tangible personal property and certain specified services. The Florida Department of Revenue sets the taxability rule: if it’s not listed in Statute 212.08 as taxable, it’s not taxable—and services almost never are unless explicitly named. Counties add their own surtax on top of that base rate. If you’re filing DR-15 returns for clients or advising them on tax categorization, you need a process that keeps each client’s county-specific rate and exemption rules straight.
How the rate works
Florida’s combined sales tax is the 6% state rate plus a county surtax that varies by location. Your client in Miami-Dade sees one combined rate; your client in Duval sees another. Rather than memorize each county’s surtax percentage, use the Florida Department of Revenue rate lookup tool to confirm the exact combined rate for each client’s county, then ensure that rate is baked into your filing process. The surtax funds county infrastructure and services, so it changes periodically—never hard-code a rate that you found last year.
How to file step by step
Filing the DR-15 (Florida Combined Sales and Use Tax Return) is a monthly or quarterly obligation depending on your client’s registration. The process starts at floridarevenue.com with the client’s Taxable Transaction Identification Number (TTIN). You’ll log into the Florida Department of Revenue system, enter the reporting period, and report total taxable sales in each taxability category—tangible goods, taxable services, nontaxable services, and so on. The system then multiplies those totals by the combined rate (6% state + the applicable county surtax) to calculate tax due. You verify the calculation, review for exemption certificates that should’ve been applied but weren’t, and submit by the 20th of the following month. Late filing triggers penalty and interest, so calendar management matters as much as math.
Each transaction your client recorded needs to land in the right category before you file. A cleaning company may have misclassified labor as taxable when it’s exempt. A reseller may have forgotten to tag inventory purchases as nontaxable resale. A contractor may have mixed taxable materials with nontaxable labor. The data-prep work—sorting transactions, applying exemptions, catching category errors—is where most of the time lives. That’s where transaction categorization saves your practice hours.
Common mistakes
Mixing up service taxability across clients. Your restaurant client’s food is taxable. Your IT consultant’s time is not. But if you’re moving fast, you might accidentally apply restaurant rules to the consultant or vice versa. The fix: confirm each client’s primary business type and the taxability of their revenue before you file. Build a one-line reference for each client—”sells tangible goods” or “exempt services”—and verify that categorization against their actual transactions.
Forgetting county surtax changes. A county updates its surtax rate mid-year. You’re still filing last year’s combined rate for transactions that happened after the change. The result is either under-payment or over-payment, caught later by the Florida Department of Revenue. The fix: check the rate lookup tool at the start of each filing cycle, not once a year. Mark surtax review as a line item in your pre-filing checklist.
Missing exemption certificates. A client bought inventory for resale but didn’t ask for or keep the reseller exemption certificate. You filed that purchase as taxable when it should’ve been exempt. The fix: ask every client about resale, contractor, or agricultural exemptions when you onboard them, and remind them to produce certificates for large purchases. Train them that “no certificate” means “we file it as taxable” so they understand the cost of forgetting it.
Filing the wrong entity or TTIN. A client with two legal entities is filing under only one TTIN, or you’re filing a proprietor’s personal return instead of the business entity’s return. The Florida Department of Revenue won’t accept the return, or it lands on the wrong account. The fix: confirm the correct TTIN and entity name on the first filing, and don’t assume it for clients with similar names or multiple locations. Cross-reference your client records with the FDR registration list before you file.
How Accumulator streamlines multi-client compliance
Running a CPA practice means you can’t manually check every transaction for every client every month. Accumulator categorizes transactions automatically and flags misclassifications before filing—so you review summaries, not thousands of line items. Each client’s county surtax and exemption rules are stored once, then applied consistently across all their filings. The DR-15 deadline reminder keeps you from missing the 20th. When you onboard a new client, you set their business type and taxability rules once; the system remembers.
You still make the final decision before submitting—no software replaces your judgment on whether a borderline transaction is taxable or exempt. But Accumulator handles the repetitive data organization and calculation, so you spend your high-value time on compliance review and client advisory, not data entry.
Frequently Asked Questions
What’s the deadline to file DR-15 in Florida?
The return is due by the 20th of the month following the reporting period. If your client files monthly, January’s return is due by February 20. If they file quarterly, the first quarter return is due by April 20. Late filing triggers penalty and interest, so calendar reminders are critical.
Do I need to track exemption certificates for every purchase?
Yes, if the customer claims an exemption—resale, contractor, agricultural, or other statutory exemption—you need the certificate on file. The burden is on you and your client to produce it if the Florida Department of Revenue audits. No certificate = no exemption = taxable sale. Keep them organized by client and purchase date.
How often do county surtax rates change?
It varies by county, but they don’t change every month. However, they do change, and the Florida Department of Revenue publishes updates. Rather than assume a rate is stable, check the rate lookup tool at the start of each filing cycle. If your client operates in multiple counties, confirm you’re using the right surtax for each location’s sales.
What happens if I file the wrong combined rate?
If you file under-payment, the Florida Department of Revenue will audit the return and bill the shortfall plus interest. If you over-pay, your client’s entitled to a refund, but processing takes time. Either way, the error creates rework. The best defense is a pre-filing checklist: confirm the combined rate (6% state + county surtax) and run it against the prior filing to verify it hasn’t changed.
Can I use the same categorization rules for all my clients?
No. A plumber and a gift shop have different taxability profiles, even if they’re both in the same county. Build a client-specific reference for taxability—”primarily tangible goods,” “primarily exempt labor,” etc.—and verify each month that transactions match that profile. This is especially important if you work with contractors, cleaning companies, or professional services firms, where labor is exempt but materials may be taxable.

Next steps for your practice
If you’re managing multiple clients across Florida, the repetitive work of transaction sorting and rate verification is eating into your advisory time. A structured process—clear categorization rules per client, automated rate lookup, and a pre-filing checklist—removes the manual overhead. Whether you build that system in-house or use tools designed for the work, consistency and speed matter. Your clients benefit from faster, more accurate filings; your practice benefits from fewer compliance surprises and rework cycles. Start with one client, document your process, then scale it.
