Sales Tax Audit Defense

Safeguarding Your Business Against Aggressive State Scrutiny

A state sales tax audit is more than a simple review of records; it is a high-stakes investigation that can result in significant assessments, penalties, and interest. As states increasingly rely on automated data-matching and aggressive nexus enforcement, even compliant businesses can find themselves defending complex technical positions. For middle-market companies and PE-backed portfolios, an unmanaged audit is a drain on internal resources and a risk to the balance sheet.

We act as your technical shield. At Calvetti Ferguson, we believe you shouldn’t face an auditor alone. Our State and Local Tax (SALT) specialists provide a high-authority defense, managing every interaction with the tax authorities. We use our deep knowledge of state-specific statutes and “audit-ready” data techniques to ensure that the auditor’s findings are fair, accurate, and minimized to the legal limit.

A Data-Driven Defense Framework

A successful audit defense is built on proactive preparation and technical counter-arguments. We manage the process from the initial Information Document Request (IDR) to the final settlement.

Strategic Audit Management

We take control of the audit environment to ensure it does not disrupt your day-to-day operations.

• • • Controlled Information Flow: We act as the sole point of contact for the auditor. By managing all document submissions and interviews, we ensure that only necessary and accurate information is shared, preventing “scope creep.”

    • Sample Methodology Review: Auditors often use statistical sampling to project errors across years of data. We scrutinize their sampling methods for bias or anomalies, often saving our clients significant sums by narrowing the sample set.

    • Technical Counter-Arguments: We identify instances where auditors misapply the law to your specific industry or product type, providing formal protest letters and legal substantiation to overturn incorrect assessments.

Institutional Protections

Our goal is to protect your capital and your reputation throughout the controversy process.

• • • Liability Quantification & Remediation: We conduct a shadow audit alongside the state to determine your true exposure, enabling you to make informed decisions about settlements or appeals.

    • Penalty Abatement: We leverage our relationships with state tax authorities and our knowledge of “reasonable cause” statutes to negotiate the waiver of aggressive penalties.

    • Post-Audit Process Optimization: An audit is a diagnostic tool. Once the defense is complete, we provide a roadmap to address the underlying systemic issues, ensuring you are “audit-proof” in the future.
