Why Hire a California Sales Tax Attorney

Stage one: the audit engagement letter

The CDTFA opens with an engagement letter, an appointment, and a records list. What happens in the first meeting sets the audit. The auditor decides which periods to test, which records to accept, and whether the business is a candidate for a markup test or a sample. Owners walk into that meeting and explain their business generously, and the auditor writes it down.

What we do: file the CDTFA-392 power of attorney so the auditor deals with us, narrow the records request to what the statute actually requires, and set the ground rules for any test before it runs. In our practice, the audits that come out well are the ones where the sample design was negotiated rather than discovered.

Stage two: the sample and the markup test

The CDTFA rarely counts every sale. It tests a block of periods or a sample of transactions and projects the error rate across the whole audit period, or it applies an expected markup to your purchases and treats the difference from reported sales as unreported. The number in the Notice of Determination comes from that math, not from your actual sales.

What we do: challenge the sample where it is not representative, insist on a proper stratified sample rather than a convenience block, document the reasons a markup test does not fit the business (theft, spoilage, promotions, price changes), and reconstruct the actual figures where records allow. A CPA can do some of this. The difference is that we are building the record for the petition and the appeal at the same time, because the auditor’s methodology is the issue that wins those.

Stage three: the audit report and the Notice of Determination

The audit ends in a report and, if there is a deficiency, a Notice of Determination. From the date on that notice you have 30 days to file a petition for redetermination. Miss the deadline and the assessment is final, collectible, and no longer appealable on the merits. Read what to do with a Notice of Determination if one is already on your desk.

What we do: negotiate the report before it becomes a notice, because the auditor’s supervisor can change the number and the appeals conference does not reliably undo what the report locked in; then draft the petition. The petition is not a form. It is the document that defines which issues the appeals conference can reach, and the arguments you leave out are usually gone.

Stage four: the appeals conference and the OTA

The appeals conference is where most CDTFA cases are actually decided. It is an informal hearing with an appeals attorney or auditor from the CDTFA’s Appeals Bureau, who has settlement authority and a duty to weigh the hazards of litigation. After the conference, the case can go to the Office of Tax Appeals, an independent panel of administrative law judges whose opinions are published, and, in a narrow set of cases, to superior court on a refund claim.

What we do: present the methodology challenge and the legal issues as a litigator would, because the appeals officer is deciding what the CDTFA would likely lose if the case went further. That is the frame that produces concessions. It is also the stage where a CPA’s representation runs out. Only an attorney can take the matter to court, and the settlement discussion changes when the other side knows you can.

Stage five: personal liability and collections

A sales tax assessment does not stay with the company. When a corporation or LLC closes owing tax, the CDTFA assesses responsible persons individually under Revenue and Taxation Code section 6829, and it pursues successors who bought the business. Interest runs, liens get filed, and bank accounts get levied.

What we do: defend the responsible person determination on its elements (control, knowledge, and willfulness are each contestable), negotiate the installment agreement or Offer in Compromise that fits the numbers, and get the levy released while the resolution is set up.

Stage six: when the file turns criminal

Sales tax collected from customers and not remitted is the fact pattern the CDTFA’s Investigations Division looks for, and a civil audit can be referred while it is still open. What you say to your CPA about that is not privileged. What you say to your lawyer is. If the audit involves cash sales, point-of-sale data that does not match the returns, or tax collected and not paid over, the representation should be structured for privilege from the first day. That is not something you can add later.

What this costs, and when it is not worth it

Most CDTFA engagements are a monthly flat fee starting at $3,500 a month, quoted for the whole matter and paused while the CDTFA is doing its part; scoped work such as a petition alone is often a one-time flat fee from $3,500. Hourly rates of $350 to $675 apply only to litigation. The pricing page has the detail.

The honest version of the value question: a clean audit with a small proposed deficiency and no sampling does not need a lawyer, and we will say so on the free call. An audit built on a sample, a markup test, a fraud penalty, multiple years, or an owner facing personal liability usually does, because the fee is small next to the swing in the number. Since December 2013 the firm has represented 400+ clients in audits and eliminated more than $100 million in tax penalties and interest, most of it in exactly these disputes.

Frequently asked questions

What does a sales tax attorney do that a CPA does not?

Three things. Privilege, so your conversations cannot be subpoenaed if the case turns criminal. The petition and appeals work, which is legal drafting and advocacy rather than accounting. And court, because only an attorney can take a CDTFA case past the Office of Tax Appeals. A good CPA is the right choice for a small, clean audit and a valuable partner inside a legal engagement.

When should I bring in a sales tax attorney?

Before the first auditor meeting if you can, because the sample design is set there. If the audit is already underway, before the audit report is finalized. If the Notice of Determination has issued, this week, because the petition deadline is 30 days.

Can a sales tax attorney get the assessment reduced?

Often, and the reductions usually come from the methodology: a sample that does not represent the business, a markup that ignores real conditions, or exemptions that were never documented. Penalty abatement is a second source. No attorney can promise a result, and any who does is describing someone else’s case.

Do I have to attend the CDTFA audit meetings?

With a CDTFA-392 on file, generally no. We attend. A factual question sometimes needs the owner, and we prepare for it. The rest of the audit runs through counsel.

Can the CDTFA settle a case?

Yes. The Appeals Bureau has settlement authority and weighs the hazards of litigation, and the CDTFA has a separate settlement program for civil disputes. Most of our CDTFA matters resolve at the appeals conference rather than at the OTA.
