California – The California Office of Tax Appeals (OTA) has received expanded authority to challenge tax regulations issued by the state’s tax agencies due to a recent opinion from California Attorney General Rob Bonta. This opinion clarifies the OTA’s ability to strike down regulations from the California Department of Tax and Fee Administration (CDTFA) and the California Franchise Tax Board if they conflict with existing tax statutes.
Taxpayer groups and practitioners are closely monitoring how the OTA will leverage this new power in its upcoming rulings. The OTA is set to release its monthly opinions on tax matters next Tuesday, which could potentially set precedents for future cases involving tax regulations.
In a significant ruling on January 31, 2025, the OTA upheld a sales tax assessment of nearly $1 million against Coast Dental Services, Inc. This decision marked a substantial use of its authority since the attorney general’s opinion. Coast Dental had attempted to classify the sale of its dental practices and assets as exempt occasional sales — a move that would have spared them from substantial tax liabilities.
The CDTFA conducted an audit of Coast Dental and determined that the sales, totaling $957,275 plus interest, constituted a series of transactions that required a seller’s permit. As per California law, sales tax is applicable to tangible personal property sales unless a specific exemption, such as the occasional sale exemption, applies.
The OTA ruled that Coast Dental’s 25 separate sales could not be deemed a single exempt sale. The ruling indicated that there was no interdependence among the separate contracts, which would necessitate their classification as a single integrated transaction. Furthermore, Coast Dental’s argument asserting that the transactions were interrelated lacked sufficient evidence. They had to demonstrate a shared intent and structured contracts backing their claim for the occasional sale exemption.
Ultimately, the OTA found that only the first two sales could potentially qualify for exemption under CDTFA regulations; subsequent sales were deemed taxable. This ruling possibly paves the way for future taxpayers who can provide adequate documentation to support their claims for tax exemptions or reductions.
The attorney general’s recent opinion not only solidifies the OTA’s authority to review conflicts between regulations and statutes but also enables the OTA to recognize regulations that may impede taxpayer rights during appeals. However, while the OTA can now evaluate these conflicts, it does not possess the power to repeal regulations broadly.
Historically, the OTA had declined to entertain statutory challenges, but this change in authority signifies a pivotal shift in how tax disputes may be adjudicated moving forward. The OTA plans to emphasize the importance of thorough documentation and meticulous planning for taxpayers seeking to appeal assessments based on claims of exemptions.
- Key Points about OTA’s Expanded Authority:
- Legal backing from California Attorney General Rob Bonta for evaluating regulations that conflict with statutes.
- Upcoming Rulings:
- OTA set to deliver key opinions on tax matters on a forthcoming Tuesday.
- Case Highlight:
- Coast Dental Services, Inc. faces a significant sales tax assessment confirmed by OTA’s ruling on January 31, 2025.
