Does California Have Sales Tax?

As of January 2019, there is no uniform federal sales tax law. However, with only a handful of exceptions, most U.S. states, including California, impose their own sales tax regulations.

In California, these regulations are enforced by an agency known as the California Department of Tax and Fee Administration (CDTFA), which was created in 2017 to take over certain responsibilities once performed by the California Board of Equalization (BOE). For example, the CDTFA is now responsible for collecting sales tax and conducting sales tax audits in California.

For these reasons, California and out-of-state retailers are required to register with the CDTFA if “engaged in business in California,” including online business. In fact, the CDTFA recently gained more power to collect sales tax from internet retailers due to a landmark Supreme Court case that was decided last year (South Dakota v. Wayfair).

While these rules apply throughout San Diego County, it is important to be aware that some cities have slightly different sales tax rates than others. For example, the city of San Diego has a sales tax rate of 7.750%, while other cities in the county, such as Vista, have a higher sales tax rate of 8.250%.

Why Did the CDTFA Choose My Business for a California Sales Tax Audit?

Just as there are many reasons the IRS can initiate an income tax audit, there are likewise numerous triggers that may lead the CDTFA to choose your business for a sales tax audit. Even if you do not think the audit is justified, it is important not to simply ignore the notices you receive, and to pay special attention to any deadlines they provide for responding. Potential reasons your business was selected for a sales tax audit include the following:

Appealing a CDTFA Sales Tax Assessment

Like the results of an IRS tax audit, the results of a CDTFA sales tax audit can be appealed, or disputed, by a taxpayer who believes that the auditor has made some sort of error, producing an incorrect outcome. If you wish to file an appeal, you must submit certain materials to the Office of Tax Appeals (OTA), which can only be done after you have received either a Notice of Action or an Appeals Bureau Decision from the CDTFA. It is important to note that sales tax audit adjustments, often related to the CDTFA conducting a mark up audit, and identifying unreported cash sales can also cause Franchise Tax Board and IRS audits and potentially even criminal tax investigations.

Your submission materials or “opening brief” must contain a thorough explanation of “the facts involved and the specific reasons you disagree with the action taken by the tax agency,” as the OTA explains. Additionally, you must provide copies of your CDTFA notices, along with “documents such as bank statements or receipts that support your case.” In lieu of a written request, you may instead submit OTA Form L‐01 (Request for Appeal). Our San Diego tax appeals attorneys can guide you through every detail of this process.

For in-depth information on this subject, you may wish to browse the CDTFA Appeal Procedures handbook, which goes into exhaustive detail explaining the steps and rules for appealing an auditor’s determination.
