Most CPAs juggle dozens of clients with spreadsheets, email threads, and manual data entry—losing hours every month to redundant work and scrambling to pull transaction reports at tax time. If you’re managing multiple client portfolios and still piecing together sales tax records by hand, Accumulator exists to reclaim that time. It’s designed to handle the transaction organization and categorization that eats up your calendar, then surfaces clean, actionable reports so you can focus on the compliance and strategy conversations that actually drive value for your practice. Florida’s combination of a 6% state sales tax plus varying county surtaxes means small-business clients often misclassify taxable sales or miss filing deadlines—and when your team has to chase down transaction records from a dozen different clients each quarter, those mistakes compound. This article walks through how Accumulator solves the portfolio management challenge, the most common mistakes you see clients repeat, and how to use data organization as a competitive edge in your practice.
Does this sound like you? You want your small-business clients organized year-round, not just at tax time. See how the platform keeps their books review-ready — your first client’s first period is completely free to try.
Does this apply to your CPA practice in Florida?
If you’re managing sales tax compliance for Florida small-business clients, the answer is yes. Florida imposes a 6% state sales tax rate on most tangible personal property and certain enumerated services; each county also layers on its own surtax, varying from 0.5% to 2.5% depending on location. The Florida Department of Revenue requires businesses to file the DR-15 (Florida Uniform Sales Tax Return) monthly by the 20th of the following month if they register to collect sales tax. The combined state and county rate determines what your client owes—and misclassifying transactions or missing those recurring deadlines directly impacts your audit exposure and client retention.
How the rate structure works in practice
Florida’s sales tax is a two-layer system: a statewide 6% base rate, plus a county surtax on top. The surtax varies by county—some are as low as 0.5%, others closer to 2.5%—so the combined rate your client pays depends entirely on where their business operates or where the sale occurs. Services are generally not taxable in Florida unless they’re specifically listed in the statute; most tangible personal property is taxable unless there’s a documented exemption. The practical effect is that when you’re reviewing a client’s transaction data, you need to know both what was sold (tangible property or service) and where the sale occurred (which county sets the surtax). Current rates and county-by-county breakdowns are published on the Florida Department of Revenue site—and they can change. Instead of memorizing rates, it’s more reliable to refer clients to that official source or a sales tax calculator, so both of you are always working from the current figures.
How to file the DR-15 step by step
The process starts with gathering all transactions for the month, categorizing them by whether they’re taxable or exempt, then calculating the tax owed based on the combined state plus county rate. On the Florida Department of Revenue portal, you’ll log into FLORIDA’s online filing system, navigate to the DR-15 return form, and enter gross sales, taxable sales, and the sales tax collected. The system then calculates the amount due based on the rate table (6% state plus your client’s county surtax). The deadline is firm: file by the 20th of the month following the sales period. Late filing incurs penalties, so consistency matters. The real friction point for most CPAs isn’t the form itself—it’s that you’re spending days reconstructing which transactions were taxable, which county they belong to, and whether the client collected tax correctly. That’s where transaction data pre-organized and categorized saves your team the audit work, letting you verify and file with confidence rather than rebuild the data from scratch.
Common mistakes CPAs see in client portfolios
Mistake 1: Not flagging service-vs.-property classifications early. A client tells you they’re a cleaning contractor—you assume everything they bill is non-taxable because “it’s a service.” But Florida taxes certain cleaning supplies and equipment if they’re sold as part of the job, and if the client bundled them with labor without breaking out the tangible component, you’re either over-collecting or under-collecting tax. The fix: review the client’s invoices and description field on their first intake, clarify in writing what’s taxable and what’s not, then categorize transactions monthly against that agreed list. If the nature of the work changes, revisit the classification—don’t assume it stays the same year to year.
Mistake 2: Missing multi-state or multi-county sales. A Florida client does a job in another state or ships to a different county within Florida. The sales tax rate changes, but if your team is bulk-categorizing all the client’s sales at one rate, you’ve got exposure. The fix: when you’re organizing transaction data, include a location field (or ask the client to tag it in their invoicing). Then categorize by county or state as the primary filter, not just by customer name. This is tedious to do manually but straightforward when your data is already categorized—you’re just reviewing and validating the geography, not recreating it.
Mistake 3: Letting exemption documentation slip. A client sells to a reseller and marks it exempt—but they don’t have a resale certificate on file. When the Florida Department of Revenue audits, you’re liable for the unpaid tax. The fix: set a policy early: no exempt transaction is recorded without a current, dated, signed exemption certificate in the file. When you’re reviewing transaction data before filing the DR-15, spot-check that every exemption claim has the backup paperwork. If it doesn’t, you can ask the client to obtain it or reclassify the transaction as taxable for that filing period.
Mistake 4: Treating the DR-15 filing as a one-time event, not a habit. Many CPAs wait until year-end or tax season to gather and file sales tax returns, which means missed deadlines, late penalties, and scrambling to reconstruct months of transaction data at once. The fix: establish a monthly routine—same day every month, the client sends over transactions or you pull them from their accounting system, you spend an hour reviewing and categorizing, then file by the 20th. This rhythm also gives you early visibility into clients whose collection or reporting is off, so you can correct patterns rather than discover problems during an audit.
Frequently Asked Questions
What’s the difference between Florida’s state and county sales tax?
Florida imposes a statewide 6% sales tax on taxable sales, and each county adds its own surtax on top—typically between 0.5% and 2.5%, depending on the county. Your client owes the combined rate; the Florida Department of Revenue collects the state portion and distributes the surtax to the county. When you’re calculating what a client owes on the DR-15, you need both numbers for their operating location or the location of the sale.
Are all services taxable in Florida?
No—most services are not taxable unless they’re specifically listed in Florida’s statute. However, certain services (like admission to entertainment events, cleaning, or pest control in specific contexts) can be taxable, or taxable when combined with a tangible good. The rule is: services are exempt unless the statute says otherwise. Always check the Florida Department of Revenue guidance for your client’s specific industry to confirm.
What happens if we miss a sales tax filing deadline?
Late filing incurs penalties and interest charged by the Florida Department of Revenue. The exact penalty structure depends on how late the return is and how much is owed, but the key takeaway is that monthly deadlines (the 20th of the following month) are firm. Setting up a recurring filing system means you can avoid these penalties altogether.
How do we document an exemption sale?
Every exempt transaction must be backed by a signed, dated exemption certificate (such as a resale certificate) from the buyer. Keep these in your client’s file organized by transaction or buyer. When you’re reviewing transaction data before filing, verify that every exemption claim has the paperwork—if it doesn’t, ask the client to obtain it or reclassify the sale as taxable. This protects both you and your client in an audit.
Can we use Accumulator to organize transactions before filing the DR-15?
Yes—Accumulator categorizes and organizes your client’s transaction data so you can review it for accuracy and compliance before filing. The tool handles the data organization work, so your team spends time on verification and strategy instead of manual entry. You can walk through the exact process here, step by step.

The habit that separates high-performing CPA practices from those drowning in compliance work is one thing: treating sales tax filing as a recurring monthly system, not a reactive scramble. If you’re still manually organizing transaction data for each client, the cost is measured in your own time and in the compliance blind spots that creep in when you’re rushing. Building that system—whether it’s a repeatable process, a tool like Accumulator, or both—is how you scale your practice without burning out your team. Start with one client, prove the monthly rhythm works, then roll it out across your portfolio.
