If you’re a business owner in California, you should be familiar with the CDTFA. The California Department of Tax and Fee Administration (CDTFA) is responsible for administering sales and use taxes, among other taxes and fees, which are vital to the state’s economy. The CDTFA focuses on sales tax audits to verify that businesses are accurately reporting and paying taxes. They generally review retailers who sell items at a retail price, and the tax calculation is based on the gross receipts obtained from the retail sales. I’m often asked by San Francisco business owners if they should be worried about a CDTFA audit? As a sales tax audit attorney, here’s what I recommend you know about a CDTFA audit.

The CDTFA is known for its distinctive audits, which are generally conducted every three years. The department carries out its audits by employing a variety of tests and techniques, and the test is influenced by the type of business being audited. The initial test carried out by the CDTFA is an in-depth comparison of the sales recorded in the business’ records and the sales reported on the sales tax return.

In addition, the CDTFA can perform a mark-up test, cash vs. credit test, use tax test, alcohol pour test, Amazon sales test, hot vs. cold, in-store and to-go test, etc. Each industry has its own set of standard tests. The CDTFA audits are very aggressive and clients are presented with a very detailed Excel spreadsheet summary that can be very difficult to understand. It’s generally advisable to work with a California sales tax lawyer to help you navigate a sales tax audit and advise you on your options if you obtain a large sales tax bill.

Common Triggers for a CDTFA Audit

While CDTFA audits can be routine, certain red flags may increase the likelihood of your business being audited. These may include the following situations:

  1. Inconsistent tax reporting: Discrepancies in reported sales or tax liabilities from year to year are common audit triggers
  2. High-risk industry: Some industries, such as restaurants, liquor stores and construction, are more frequently audited due to the complexity and variability of their transactions
  3. Frequent amendments or late filings: Regularly amending tax returns or consistently filing late are also red flags — not just to the CDTFA, but to the IRS as well
  4. Audit history: If your business has been audited in the past and discrepancies were found, CDTFA may conduct follow-up audits
  5. Third-party reports: Sometimes when customers, vendors or other third parties make reports that contradict your figures, those notifications may trigger an audit

If your business is selected for a CDTFA audit, you will receive an official notice in the mail informing you of the audit, including its scope and the period it will cover. The auditor will then request records, which may include sales receipts, invoices, tax returns and financial statements. The auditor may also conduct interviews with business owners and employees. If deemed necessary, the auditor may also visit the business premises to understand operations better. After reviewing the documents, interviews and information gathered, the auditor will present their initial findings and give the business owner the opportunity to discuss or dispute any discrepancies. Finally, the auditor will issue a final report, which could result in a determination of additional taxes owed, refunds due or no change.

Do not try to navigate a CDTFA audit on your own. Reach out to an experienced California tax audit attorney or CDTFA audit lawyer to help you navigate a sales tax audit and advise you on your options if you obtain a large sales tax bill.

I can't recommend Allison enough! She helped me successfully navigate a stressful EDD audit with expertise and grace. Not only is she incredibly smart and thorough, but she's also genuinely kind—something you don’t always expect from an attorney. Her support and guidance made all the difference. If you need a tax attorney who knows her stuff and truly cares, she's the one to call!

2024- Working with Allison has been an incredibly smooth experience both times I’ve worked with her. Her expert advice and the support she provides are outstanding, and we’ve had nothing but positive results each time. 2020- I was so impressed with her work during an EDD audit. I would HIGHLY recommend Allison to anyone going through an EDD Audit. From the very first 3 minutes of speaking with her, she was super helpful and professional, while also making me feel like I was talking to a friend, which really helped calm my anxiety. Allison was dedicated to helping us achieve the best possible outcome and was honest about all scenarios, even preparing us for the worst. We ended up with the VERY best outcome because of how she guided us through the process and made sure we had everything ready to tell our story to the auditor. If you want someone who truly listens, understands your business, and will be your biggest advocate, call Allison now! Be ready because she’s quick to respond with both calls and emails.

We retained the services of Allison Soares for a recent IRS audit. The IRS was claiming we owed an exorbitant amount of money. After interviewing several qualified attorneys, Allison was the obvious choice. During this very stressful time for our family, we appreciated how knowledgeable and responsive she was from the very first call. Her professionalism and commitment to our case was truly impressive. She pointed out a few critical points, that another attorney may have missed, which we believe helped our case immensely. She guided us through this complicated process with great success and we could not have been happier with the outcome of the audit. We are 100% satisfied with her work and would highly recommend her to anyone seeking legal tax advice. Thank you so much Allison, we are truly grateful for all your hard work.
