If you have received a Florida Department of Revenue audit notice, you have rights and you have time to plan, but only if you act promptly. A sales tax audit is not a passive review; it is an adversarial process in which the state Department of Revenue is actively working to determine whether additional tax is owed. An experienced sales tax attorney can manage communications with the auditor, negotiate the scope and methodology of the examination, challenge proposed assessments with documentary evidence, and pursue appeals if the Department’s findings are wrong. The earlier legal counsel is involved, the more options are available.

Florida sales and use tax audits are conducted by the Department of Revenue under Chapter 212, Florida Statutes. Understanding how audits are initiated and how they proceed is the first step in responding to one effectively.
What Triggers a Florida Sales Tax Audit
The Department of Revenue selects businesses for audit through a combination of risk-based targeting, industry focus, third-party information, and random selection. Businesses in certain industries carry elevated audit risk based on historical noncompliance patterns. Some common examples are restaurants, contractors, auto dealers, healthcare providers, technology companies, and businesses with significant exempt sales. Other common triggers include discrepancies between a business’s Florida corporate income tax return and its sales tax returns, discrepancies between sales on the business’s sales tax returns and income reported by payment processors on Form 1099k, tips from former employees or competitors, and follow-up examinations after a prior audit that identified deficiencies.
The Audit Notice and Initial Information Request
An audit begins when the Department of Revenue issues a Notice of Intent to Audit Books and Records, Form DR-840. This notice identifies the tax type under review and the audit period, which is generally the prior three years. The business has 60 days from the notice date to gather and organize its records before the auditor begins the examination. The Department of Revenue will issue a records request specifying what it needs: financial statements, sales journals, purchase invoices, exemption certificates, contracts, and point-of-sale reports are standard requests. How a business responds to the initial records request, what it produces, how it is organized, and what context it provides, will shape the tone of the entire audit.
Audit Timeline
Florida sales tax audits typically take between six and eighteen months from the date of the initial notice to the issuance of a proposed assessment, depending on the complexity of the business, the condition of its records, and the number of issues the auditor identifies. Audits involving statistical sampling, multiple locations, or contested taxability questions tend to run longer. Businesses that sign statute of limitations extensions should understand that doing so extends the window during which the Department of Revenue can assess tax and should not be done without careful consideration.
Florida tax audits follow a structured methodology based on the type of tax being reviewed, but the specific issues an auditor focuses on depend on the nature of the business. The following are the most common categories of audit findings.
Unremitted Sales Tax on Taxable Transactions
The auditor will review the business’ sales and purchase records to identify transactions on which tax should have been collected or paid but was not. This includes sales to customers who claimed an exemption but for whom the business cannot produce a valid, current exemption certificate, sales of taxable services that the business misclassified as non-taxable, and transactions in which tax was collected but not remitted in full.
Exempt Sales Without Proper Documentation
Florida law places the burden on the seller to prove that an exempt sale was legitimate. If a business made sales without collecting tax, the business must produce valid exemption certificates for each buyer to support those transactions. Missing, expired, or invalid certificates convert exempt sales into taxable ones in the Department of Revenue’s calculation. For businesses with high volumes of exempt sales, this is frequently the largest single category of audit exposure.
Use Tax on Taxable Purchases
Florida’s use tax applies to taxable goods and services purchased without paying Florida sales tax. Some common examples are purchases from out of state seller who did not collect Florida sales tax, and items removed from inventory for internal use. Auditors review purchase records and accounts payable to identify items that should have been subject to use tax and were not.
Manages All Department of Revenue Communications
One of the most important functions of audit representation is controlling the flow of information between the business and the Department of Revenue. When an attorney is engaged, Department of Revenue communications are directed to counsel rather than to the business’s employees or owners. This prevents inadvertent disclosures, ensures that responses to the records request are complete and strategically framed, and keeps the auditor’s focus on the issues that are actually within scope. Business owners and employees who speak directly with auditors without counsel present frequently volunteer information they were not required to provide, expanding the scope of the examination unnecessarily.
Negotiates Scope and Methodology
The audit period, the transaction types under review, and the sampling methodology are all subject to negotiation. Auditors are not required to accept the first sampling design they propose, and a business with counsel can challenge a proposed sample on statistical grounds, propose an alternative sample, or argue for a transaction-by-transaction review of specific issue areas. Scope and methodology decisions made early in the audit have a compounding effect on the final assessment figure.
Challenges Proposed Assessments
Once the Department of Revenue issues a Notice of Intent to Make Audit Changes and a Notice of Proposed Assessment, the business has the right to contest the findings before the assessment becomes final. An attorney can review the auditor’s workpapers, identify legal and factual errors in the Department of Revenue’s calculations, gather documentary evidence to support corrected figures, and present a written challenge to the proposed assessment. This phase is often the most productive opportunity to reduce the liability.
Files Protests and Appeals
If the proposed assessment is not resolved at the field level, the business may file a written Protest to transfer the matter to the Department of Revenue’s Informal Dispute Resolution group in Tallahassee. A conference is scheduled, legal and factual arguments are presented, and the Department of Revenue issues a Notice of Decision. If the dispute remains unresolved, the business may petition for a formal administrative hearing before the Division of Administrative Hearings (DOAH), where the matter is litigated before an Administrative Law Judge. Ribeiro Law handles each stage of this process.

How long do I have to respond to a Florida sales tax audit notice?
The Notice of Intent to Audit Books and Records gives the business 60 days to gather records before the examination formally begins. This is not a deadline to retain counsel but rather a window to organize documentation and prepare for the audit. Engaging an attorney within the first few days of receiving the notice is advisable. The 60-day period passes quickly when records need to be located, reconciled, and organized across multiple years, and the condition of your records at the opening conference sets the tone for the entire audit.
Can I represent myself in a Florida Department of Revenue audit?
There is no legal requirement to retain professional representation for a Department of Revenue audit. However, a sales tax audit is an adversarial proceeding in which the Department of Revenue is attempting to determine whether additional tax is owed, and in which the auditor has significant discretion over scope, methodology, and how to treat ambiguous transactions. Businesses that manage their own audits without professional assistance frequently make avoidable errors: producing documents they were not obligated to produce, agreeing to unfavorable sampling designs, failing to raise available legal defenses, or missing protest deadlines that permanently close off their appeal rights. For audits involving significant proposed liabilities or legally complex transaction types, the cost of representation is typically far less than the cost of an uncontested assessment.
What happens if I ignore a sales tax audit?
Ignoring a Department of Revenue audit notice does not stop the audit. The Department of Revenue will proceed without the business’s cooperation, estimate the tax liability based on available data, and issue a proposed assessment. That assessment will become a final assessment if it is not protested within 60 days. A final assessment can be collected through a tax warrant, which creates a lien against all of the business’s Florida property, followed by bank account levies, garnishment of receivables, and, ultimately, seizure of assets. The opportunity to challenge the assessment through the administrative process is lost once the protest window closes.
What is the penalty for a failed Florida sales tax audit?
Florida’s penalty structure for sales tax deficiencies is tiered based on the nature of the noncompliance. A standard audit deficiency carries a penalty of 10% of the tax due if filed late and 10% for failure to pay, with a combined maximum penalty of 20% in most cases. Where the Department of Revenue determines that the taxpayer had a substantial underpayment — defined as an underpayment exceeding the greater of $1,000 or 10% of the correct tax due — a 30% negligence penalty may apply. Fraudulent or intentional evasion carries a 100% penalty. Interest accrues daily on the unpaid balance at a floating rate set by the Department of Revenue. Penalty abatement is available in certain circumstances, including reasonable cause and first-time abatement for businesses with clean prior compliance histories.
