How to Respond to a Sales Tax Audit Notification

Updated: Jun 28

Receiving a sales tax audit notification can feel overwhelming, especially if your business operates across multiple states or handles a high volume of transactions. But don’t panic—being proactive, organized, and well-informed is key to managing a sales tax audit successfully.


Whether you're a growing e-commerce store or a service-based company, understanding how to respond to an audit notice is essential to avoid penalties, interest, and reputational damage.

In this article, we'll guide you through the steps to take when you receive an audit notice and explain how Manage My Sales Tax can support you through the process.


What Triggers a Sales Tax Audit?

Sales tax audits don’t happen randomly. States usually initiate audits based on a few common red flags:

  • Late or inconsistent sales tax filings

  • Large discrepancies in reported sales

  • Excessive exemption claims

  • Tip-offs from customers or competitors

  • Randomized state compliance initiatives


Step-by-Step: How to Respond to a Sales Tax Audit Notification

1. Stay Calm and Read the Notice Carefully

The audit notification will include:

  • The audit period being reviewed

  • Required documentation

  • Deadlines for response

  • Contact information for the assigned auditor


Tip: Make note of all deadlines and begin gathering requested documents immediately.


2. Contact the Auditor (or Let Your Consultant Do It)

You don’t have to go through this alone. It’s highly advisable to have a tax expert or representative manage communication with the auditor. If you choose to respond yourself:

  • Be professional and polite

  • Ask for clarification if needed

  • Confirm what formats they prefer for documentation


3. Review Your Records Before Sharing

Before submitting any documents, perform your own internal audit to identify:

  • Missing records or discrepancies

  • Uncollected taxes

  • Unfiled returns

This allows you to fix potential issues or prepare a defense for your position.


4. Gather and Organize Required Documentation

Typical documents include:

  • Sales reports by state and month

  • Sales tax returns and payment confirmations

  • Exemption certificates (if applicable)

  • General ledgers

  • Purchase invoices


Pro Tip: Provide digital files in clear folders (e.g., "Sales 2023 – TX") to show professionalism and cooperation.


5. Respond Promptly and Professionally

Meet all deadlines, and keep a paper trail of every communication. If additional time is needed, request it in writing and explain why.


6. Correct Errors Proactively

If you identify errors in previous filings, it's better to correct them proactively. Some states offer reduced penalties for voluntary disclosure.


7. Prepare for an On-Site or Remote Audit

Auditors may request on-site visits or remote access to your accounting software. Ensure your systems are clean, organized, and accessible.


8. Understand Your Rights and Appeal Options

After the audit, you'll receive a preliminary assessment. If you disagree:

  • Request a conference

  • Submit additional documents

  • File a formal appeal within the specified timeframe
