What to do When you Get a Notice From the State
All posts
Receiving a notice from the state can stop you in your tracks.
Your first thought might be: Did we do something wrong? Are we being audited? How serious is this?
Take a breath.
Sales tax notices are common. State tax agencies send millions of notices each year for routine compliance issues. Not every sales tax notice means penalties, audits, or legal trouble. Many are automated reminders or requests for clarification.
That said, acting quickly matters. Ignoring a notice from the state can lead to added penalties, interest, or escalation.
Here’s what you need to know and what to do next.
There are several legitimate reasons you may receive a notice from the state or a state tax notice related to sales tax. Most fall into predictable categories.
Common reasons include:
Since the 2018 South Dakota v. Wayfair Supreme Court decision, states can require out-of-state businesses to collect sales tax if they exceed certain economic thresholds. If your business has grown, your nexus footprint may have expanded without you realizing it.
Not every sales tax notice indicates wrongdoing. Often, it simply means the state needs clarification or believes something is missing.
Understanding what type of notice you received helps determine how serious it is.
This is typically the least severe type of notice.
It usually indicates a return was not filed or was filed late.
In many cases, if the return is filed promptly, penalties may be limited or avoided depending on state rules.
This notice states that the agency believes you owe additional tax, penalty, or interest.
It may be based on:
These notices require review. States can issue assessments based on estimates if returns are missing.
An audit notice means the state intends to examine your records more closely.
Audits may be random, industry-targeted, or triggered by inconsistencies in filings. An audit does not automatically mean fraud or intentional noncompliance — but it does require careful handling.
If a return or payment was late, states commonly assess:
Interest accrues over time and typically cannot be waived unless permitted under specific state rules.
States may send notices asking why your business is not registered.
These often follow:
This type of notice may indicate the state believes you triggered nexus.
If you’re wondering how to respond to a sales tax notice, follow these steps.
It sounds obvious, but it happens more than you think.
Even if you believe it was sent in error, it requires a response.
Identify:
Each notice includes a response timeline.
Deadlines matter.
If you intend to dispute the notice, many states require protests or appeals to be filed within a strict statutory timeframe.
Missing that deadline can limit your options.
Before you respond to a state tax notice, collect:
You need facts before responding.
It’s important to understand the full exposure before communicating with the state.
In some cases, responding too quickly without reviewing nexus, historical liability, or registration status can create additional complications.
If you disagree with the state’s determination, you may have the right to file a protest.
Understanding how to protest a sales tax notice can protect your business from incorrect assessments.
You may consider filing a sales tax appeal if:
Each state has formal procedures for protesting a state tax notice.
While procedures vary by state, the general process includes:
Most protests must be submitted in writing and within a defined time window.
After filing:
If you disagree with that determination, further appeal rights may exist depending on state law.
Failing to respond can lead to:
States have statutory authority to pursue collection of assessed taxes.
Addressing issues early typically provides more options than waiting until enforcement begins.
The answer depends on the complexity of the issue.
You may be able to respond internally if:
Professional guidance may be appropriate if:
Sales tax laws vary by state, and procedural errors during appeals can limit options.
Resolving a state notice often requires more than simply responding.
Experienced sales tax professionals can assist by:
Real accountants and consultants understand how states administer sales tax and how to navigate compliance issues effectively.
Prevention is possible.
Businesses can reduce risk by:
Starting with nexus is foundational. Identifying where you have an obligation is the first step toward compliant filing.
When your sales tax process is structured and reviewed regularly, you reduce surprises.
A notice from the state doesn’t automatically mean penalties, audits, or worst-case outcomes.
But it does require attention.

If you receive a notice from a state tax authority, the first step is to read the notice carefully and verify the details. Check the tax period, the issue identified, and any deadlines for response. Most notices require a response within a specific timeframe, so businesses should review their records and respond promptly to avoid additional penalties or interest.
States typically send tax notices when they identify missing filings, unpaid taxes, registration issues, or discrepancies in reported sales. In many cases, the notice is simply a request for clarification or documentation rather than a penalty.
Ignoring a tax notice can lead to additional penalties, interest, enforced collections, or even an audit. In some cases, the state may estimate your tax liability based on available data, which can significantly increase the amount owed.
Response deadlines vary by state, but many notices require a reply within 15 to 30 days. The notice will typically include instructions on how to respond and whether documentation must be provided.
Yes. In some situations, a notice is the first step in a broader compliance review. If the issue cannot be resolved with documentation or clarification, the state may open a formal tax audit.
Businesses should collect sales records, tax filings, exemption certificates, transaction reports, and registration documentation related to the period referenced in the notice. Having complete records helps resolve the issue more quickly.
If the notice involves large tax amounts, nexus questions, or potential audit exposure, it may be helpful to work with a sales tax professional. Experts can help review the notice, communicate with the state, and ensure the response is accurate.
