News Summary
California has enhanced the authority of the Office of Tax Appeals (OTA), allowing it to challenge tax regulations conflicting with state statutes. This change, prompted by an opinion from Attorney General Rob Bonta, is anticipated to provide taxpayers with greater power during appeals. The OTA’s first monthly opinions under this new authority will be issued soon, and the implications for tax policy are significant, especially following a recent ruling against Coast Dental Services regarding taxable sales.
California has expanded the authority of the Office of Tax Appeals (OTA) to challenge tax regulations set forth by the state’s tax agencies. This development comes following a recent opinion issued by California Attorney General Rob Bonta, clarifying that the OTA can now strike down regulations that conflict with state statutes during taxpayer appeals. The changes have garnered significant attention from taxpayer groups and legal practitioners, who are eager to see how the OTA will exercise this newfound power.
Following the attorney general’s decision, the OTA is preparing to issue its monthly opinions on tax matters this coming Tuesday. This will be the first opportunity for the public and tax professionals to understand the implications of the new authority. The OTA’s ability to evaluate conflicts between regulations and statutes signals a potential increase in the office’s influence over tax policy.
In a notable instance of this new power, the OTA recently upheld a substantial sales tax assessment against Coast Dental Services, Inc. In a decision set forth on January 31, 2025, the OTA ruled against Coast Dental’s attempt to classify the sale of its dental practices and assets as “occasional sales,” which would have exempted them from sales tax. The California Department of Tax and Fee Administration (CDTFA) had audited Coast Dental and determined that the transactions fell under taxable sales requiring a seller’s permit.
The CDTFA issued a Notice of Determination for a total tax liability of $957,275, including interest, prompting Coast Dental to appeal the assessment. Under California law, sales tax applies to tangible personal property unless a specific exemption, such as the occasional sale exemption, is established. However, the OTA concluded that Coast Dental’s 25 separate sales did not qualify as a single exempt sale. The ruling emphasized that the sales were independent transactions with no interdependence justifying an integrated transaction under tax regulations.
Coast Dental’s argument asserting that the sales were interrelated was deemed insufficient. The OTA required demonstrable evidence of shared intent and structured contracts to qualify for the exemption. Ultimately, the OTA ruled that only the first two sales could potentially be exempt under CDTFA guidelines, while the remaining sales were deemed taxable. This ruling leaves the door open for other taxpayers who can provide adequate documentation to support their claims in similar situations.
The opinion from the Attorney General marks a significant shift in the OTA’s operational scope, allowing it to review and potentially invalidate regulations during taxpayer appeals. Historically, the OTA refrained from considering statutory challenges but now possesses the authority to assess issues where there are conflicts between regulations and state laws. However, it is important to note that this ruling does not enable the OTA to repeal regulations wholesale.
Taxpayer advocates and practitioners are particularly encouraged by this clarification, which emphasizes the importance of thorough documentation and careful planning for those challenging tax assessments. With more authority to navigate the complexities of tax law, the OTA may play a more critical role in shaping tax policy and resolving disputes between taxpayers and tax agencies.
As taxpayers await the OTA’s next opinions, the implications of the attorney general’s opinion will likely become evident, shaping how future appeals are handled and potentially impacting tax regulations in California.
