You’re deep in Q1, March is closing in, and your CPA just sent a reminder: we need your books by March 15. Your stomach drops. You have bank statements scattered across three different cards, sales from cash transactions you haven’t categorized, a stack of receipts, and no idea whether you’ve calculated your sales tax correctly. You’re not behind on paying taxes—you just don’t know if your records match what you owe. The March 15 deadline for getting your books to your CPA is a real turning point: miss it, and your tax return gets delayed; rush it and send messy data, and your CPA will charge you for the cleanup work. This checklist walks you through what “getting your books ready” actually means, what you can organize yourself, and where to focus your effort so your CPA can review and file your return on time.
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?
If you’re a sole proprietor or own an S-corp filing Schedule C and you operate in Florida, you need to have organized transaction records ready for your CPA by March 15 so they can file your federal return by April 15. This includes federal income tax data and any sales tax you’ve collected (if applicable in your industry). The Florida Department of Revenue requires sales tax filers to report by the 20th of the following month, so your CPA needs your sales data finalized by mid-March to file accurately and on schedule.
How the rate works
Florida’s sales tax has a straightforward structure: a 6% state rate plus a county surtax that varies by county where you operate. If you sell tangible personal property, you collect tax on the sale price. If you provide services, Florida’s general rule is that services are not taxable unless they’re specifically listed in Statute 212.01. This is where many contractors and service providers get tripped up—you may think you owe sales tax on labor, but you likely don’t unless your county or industry has a specific carve-out. Your combined rate (state + surtax) depends on which county you’re in. Rather than trying to memorize rates, use the Florida Department of Revenue‘s rate calculator or contact them directly to confirm the current combined rate for your location and business type. Rates can change, and counties sometimes adjust surtaxes, so don’t rely on last year’s number.
How to file step by step
Once you have your organized transaction data ready, your CPA or bookkeeper will prepare a sales tax return (Form DR-15 if you’re filing with the Florida Department of Revenue). Here’s what the process looks like: First, gather all your sales and purchase records from the tax period—these are the numbers your CPA will need. Second, your CPA will categorize taxable sales (tangible property in Florida, plus any services that fall under the specific taxable categories), non-taxable sales (most services, unless listed), and purchases that were exempt or resold. Third, they’ll calculate the tax due based on the state 6% rate plus your county’s surtax, and confirm your filings match what you’ve actually paid in advance. Fourth, your CPA files the return electronically or by paper before the 20th of the following month. If you want to understand the filing process yourself—or even file directly with help from a guide—you can access Form DR-15 on the Florida Department of Revenue website. However, having organized books beforehand makes the entire process faster and cheaper, since your CPA won’t have to spend hours categorizing every transaction themselves.
Common mistakes
Mixing personal and business transactions. If you use your business bank account to pay personal expenses—or vice versa—your CPA has to manually separate them during review. This adds hours and cost. Before sending your books to your CPA, do a final scan of your bank and credit card statements and flag anything personal so they know to exclude it. A simple note (“grocery store charge—personal”) next to each one saves time.
Forgetting cash sales and tips. Many service-based businesses (cleaners, contractors, consultants) receive cash payments that don’t hit the bank automatically. If you don’t log them, your sales total will be artificially low, and so will your calculated sales tax. Keep a running log of cash sales by date and amount, and send it to your CPA with your books. The same goes for tips your team receives—if you’re collecting and reporting them, they need to be in your records.
Assuming all your sales are taxable (or none are). Contractors often think they owe sales tax on labor—they don’t, unless they’re in a specific category. Cleaning companies sometimes think they’re exempt—they usually aren’t. Rather than guessing, confirm your industry’s tax status with the Florida Department of Revenue or your CPA before your books go in for review. A five-minute call now prevents a reclassification later.
Sending unreconciled bank statements. Your CPA needs to know that your recorded transactions match your actual bank deposits. Before you send your books, reconcile each bank and credit card account—that is, match the ending balance on your statement to the total in your records. If there’s a discrepancy, flag it. Unreconciled accounts force your CPA to hunt for missing or duplicate entries, which eats time and money.
What “getting your books ready” means in practice
Getting your books ready doesn’t mean hiring a bookkeeper or doing a full accounting overhaul. It means organizing the raw data your CPA needs to review and file. You can do this yourself by gathering receipts, bank statements, and a simple spreadsheet that lists each sale, purchase, and transfer. Or, you can use a platform like Outsourcing Processing to categorize transactions automatically as they post to your accounts, calculate sales tax in real time, and produce a clean report your CPA can review in minutes instead of hours. Either way, the goal is the same: get clean, organized data to your CPA before March 15 so they have time to file your return by April 15.
If you’re managing books for multiple small businesses, or you’re a CPA supporting growing clients, consider whether outsourcing the data organization piece makes sense—many back-office teams find that automating transaction categorization and tax calculation frees up time for higher-value advisory work. An affordable monthly membership can be far cheaper than asking your CPA to manually sort every transaction.
The week before you send your books
A few days before the March 15 deadline, do a final check: confirm all deposits are recorded, flag any gaps or odd amounts, reconcile your bank and credit card accounts, and compile your sales tax records. Send your CPA a brief note listing what you’re including and what questions or discrepancies you found. A five-minute email preventing confusion later is worth it. Then follow up with a call to confirm they received everything.
Frequently Asked Questions
What if I miss the March 15 deadline?
Your CPA can request a six-month extension for your federal return (until October 15), but you should still file your Florida sales tax return by the 20th of each month. Notify your CPA immediately if your books will be late so they can adjust their filing timeline and let you know if there’s any impact.
Do I need to file sales tax separately if I’m a sole proprietor?
Only if you’ve collected sales tax. If you sell tangible property or provide a taxable service in Florida, yes—you file Form DR-15 and remit tax by the 20th of the following month. If you provide non-taxable services (the general rule for most services in Florida), you may not have a sales tax obligation. Confirm your situation with the Florida Department of Revenue or your CPA before assuming you’re exempt.
Can my CPA file my return if my books aren’t perfect?
Yes, but they’ll charge you for the time it takes to clean them up. The messier your data, the more billable hours. Organized books save you money in accounting fees and reduce the risk that something gets missed or miscategorized.
What should I do with receipts I can’t find?
If you have a credit card statement showing a business purchase but no receipt, the statement is usually enough to justify the expense. However, if you’re audited, the IRS may ask for more detail. For the March 15 deadline, just note which receipts are missing and let your CPA know so they can flag them in the file.
How early can I send my books to my CPA?
The earlier, the better—ideally by early March so your CPA has time to review, ask clarifying questions, and file without rushing. If you can organize your books by February 28, you’ve given your CPA a full two weeks to work and still meet the April 15 federal deadline comfortably.

Next steps
Start this week: list what records you have and what you’re missing. If organizing everything yourself feels overwhelming, that’s normal—many business owners reach a point where outsourcing the data organization saves more time than it costs. Your job is running your business, not sorting receipts. By mid-March, your CPA should have everything they need to file your return on time, and you’ll know your tax situation is handled. That peace of mind is worth the effort now.
