Audit Defense & Notice Response
If a state audit notice landed on your desk this morning, would you know what the state was really asking for, or how much information or data you actually have to hand over?
Most companies don’t, and that’s the hard part. The letter rarely tells you how big the matter is. What looks like a routine request for records can stay small, or it can open into questions about nexus, prior-year filings, how your sales and purchases are taxed, and how your software was set up. The uncertainty is usually worse than the audit itself.
We do this every week, and a good part of our value early on is helping you evaluate the kind of outreach the state is engaged in, and possible next steps.

You Got an Audit Notice. Now What?
Monika and Bill explain what a state audit notice actually means, how companies get selected, and the first moves that protect you. Everything you need to know if a notice just landed on your desk.
The “Kitchen Sink” Letter
That first letter usually asks for everything: every return, every exemption certificate, every record across a span of years. Sometimes we call it the kitchen sink letter, because the state leads by requesting far more than it needs and lets you sort out what matters.
Here’s the thing worth knowing: you don’t have to answer all of it, and you don’t have to answer it tomorrow. A lot of the early damage in an audit comes from companies feeling pressured to hand over everything quickly, before anyone has figured out what the state is actually after or how the business operated during the years under review. The first real move isn’t to respond. It’s to understand the request.
The Work We Actually Do During an Audit
In most audit situations , we sit between you and the auditor. You keep running the business; we handle the back-and-forth (the document requests, the questions, the meetings) and we translate what the auditor is really driving at.
That role matters more because of who’s doing it. Our team includes advisors who have spent many years working directly with state auditors . We know how an auditor builds an assessment, where the soft spots in their methodology tend to be, and which arguments actually move a number versus which ones just annoy the person across the table. A large share of a final assessment often comes down to two things an experienced hand can push on: the sampling method the auditor used to extrapolate across years, and exemptions that were disallowed but shouldn’t have been.
Two Things Most Companies Don’t Know to Ask
First, in California, there’s a managed audit program that can cut the interest on an assessment by half if you qualify and the audit is handled the right way. Knowing whether you’re eligible (and setting the audit up to use it) can meaningfully change what you end up paying.
Second, audits don’t only find money you owe. Sometimes they turn up tax you overpaid: exemptions you didn’t take, or positions you ran more conservatively than you had to. When that’s the case, we’ll look at whether a refund or a reverse-audit claim belongs in your response, so the conversation isn’t only about exposure.
An Audit Can Point to Something Bigger
Occasionally a single-state audit is the first sign of a broader question: whether the same issue is waiting in other states too. In some you may have filed nothing at all; in others you’ve been filing, but on the wrong assumptions. Often it traces back to economic nexus: thresholds that quietly created obligations no one was tracking.When that’s the case, the audit becomes the moment to get ahead of it rather than wait for the next letter. We’ll help you see whether the matter is contained or wider, and if it’s wider, our Multi-State Sales Tax Strategy and Voluntary Disclosure pages pick up that thread.
Success Story
A $1M Assessment That Didn’t Hold
A multi-state distributor managed a California audit on its own for nearly a year and ended up with a proposed assessment north of $1 million. By the time they brought us in, the number looked final to them. It wasn’t. We challenged how the auditor had sampled and extrapolated the transactions, defended exemptions that had been thrown out, and brought the proposed liability down by more than $500,000.
Frequently Asked Questions About Tax Audit Defense and Support Services
The notice will give you a deadline, and you should meet it , but meeting it rarely means handing over everything by that date. Deadlines are real and shouldn’t be ignored, yet the worst outcomes usually come from over-responding before you understand the information request . The right first step is figuring out what’s actually being asked, then responding deliberately often a short, professional request for clarification or a brief extension, not a box of records.
Not by itself. Some notices stay narrow and close quickly. Others open up. You generally can’t tell from the letter alone, which is exactly why an early read from someone who has experience with the other side is worth more than a guess.
It can; not necessarily because states coordinate, but because the issue an auditor finds often exists everywhere you sell or have operations. That’s worth knowing early, because it changes whether you treat the audit as a one-off or as a prompt to look wider before someone else does.
Yes, routinely, with your CPA, your attorney, your software provider, and your finance team. Much of our work comes by referral from exactly those advisors, and we’re comfortable being the sales-tax specialist inside a team that already knows the rest of your business.
Absolutely. While we recommend getting us involved at the beginning, we often enter the picture once a client either feels overwhelmed or senses that the audit isn’t going well.
Let’s Take a Look at the Notice Together
Most companies call us before they know how serious the matter is. That’s the right time to call, not the wrong one. A first conversation usually settles three things: what the state is really reviewing, whether the issue is contained or points to something wider, and how to respond so the audit goes as well as it reasonably can.
