If you receive a sales tax notice, do not ignore it. States often send notices when they believe your business may have unreported sales tax obligations, missing filings, or nexus exposure. The best approach is to review the notice carefully, assess your exposure, and respond strategically before penalties escalate.
Why Did I Receive a Sales Tax Notice?
A sales tax notice is usually sent when a state believes your business may have sales tax obligations that have not been properly addressed.
This may happen because:
- You exceeded economic nexus thresholds
- Your business has inventory in the state
- Marketplace or payment processor data triggered a review
- You missed filings or payments
- The state identified inconsistencies in your records
Receiving a notice does not automatically mean you are being fully audited but it should always be taken seriously.
The most important thing to remember is that if you receive a sales tax notice, you should review it immediately and assess your potential sales tax exposure before responding or registering incorrectly.
Why States Send Sales Tax Notices More Frequently Now
States have become significantly more aggressive with sales tax enforcement in recent years.
This is largely due to:
- Economic nexus laws
- Increased ecommerce activity
- Marketplace reporting requirements
- Payment processor data sharing
States now use:
- Amazon marketplace data
- Shopify and Stripe transaction information
- 1099-K reports
- AI-driven compliance systems
This means businesses are easier to identify than ever before.
Common Types of Sales Tax Notices
Not all notices mean the same thing.
Understanding the type of notice is important because:
- Some are informational
- Others are much more serious
1. Nexus Inquiry Notice
This is one of the most common notices for ecommerce businesses.
The state believes:
- You may have exceeded nexus thresholds
- You may be selling into the state without registration
These notices often ask:
- Whether you have sales activity in the state
- Your revenue levels
- Whether you are registered elsewhere
These notices are often triggered by marketplace or payment data.
2. Failure to File Notice
This occurs when:
- You are already registered
- But returns were not filed
Even:
- Zero-dollar returns may still be required.
- States may estimate liabilities if returns are missing.
3. Audit Notice
An audit notice is more serious.
This means:
- The state intends to review your sales tax compliance
- Historical records may be requested
This can include:
- Sales records
- Exemption certificates
- Marketplace reports
- Bank statements
4. Assessment Notice
An assessment notice means:
- The state believes tax is owed
- Penalties and interest may already be applied
At this stage, immediate action is critical.
What Should You Do Immediately?
The worst mistake is ignoring the notice or responding too quickly without understanding your exposure.
Step 1: Read the Notice Carefully
Review:
- The state involved
- The tax periods referenced
- Deadlines
- Information requested
Small details matter.
Step 2: Do Not Ignore Deadlines
Failing to respond may:
- Escalate enforcement
- Increase penalties
- Trigger assessments or audits
Step 3: Assess Your Sales Tax Exposure
Review:
- Sales by state
- Marketplace activity
- Inventory locations
- Nexus thresholds
You need to understand whether the state’s concerns are valid.
Step 4: Avoid Panic Registration
Many businesses immediately register after receiving a notice.
This can be risky because:
- Registration may waive certain protections
- It can complicate voluntary disclosure options
- Historical liability may increase unnecessarily
Strategy matters.
Step 5: Gather Documentation
This may include:
- Sales reports
- Marketplace data
- Resale certificates
- Prior filings
- Nexus analysis
What Happens If You Ignore a Sales Tax Notice?
Ignoring a sales tax notice is usually the most expensive option.
Possible consequences include:
- Estimated tax assessments
- Increased penalties and interest
- State liens or collections
- Audit escalation
States generally continue enforcement until the issue is resolved.
Can You Reduce Penalties or Historical Liability?
In many cases, yes. Sometimes simply filing the sales tax return can clear the penalty and estimated delinquency applied to the account.
Options may include:
- Voluntary disclosure agreements (VDAs)
- Negotiated settlements
- Corrected filings
- Compliance plans
The earlier you act, the more options you typically have.

Common Mistakes Businesses Make
