California Tax Disputes in California
A California tax dispute has its own notices, deadlines and review process. An IRS matter and a state matter may involve related facts without following the same timetable. Individuals, business owners and companies need to understand which agency is acting and which decision is currently open to challenge.
RV Litigation Group PC assists with California tax controversies, including Franchise Tax Board examinations, protests of proposed assessments and appeals to the Office of Tax Appeals. We focus on the disputed legal and factual issues and the records needed to support the client’s position.

State Tax Issues Require a Specific Record
Individual income and residency issues
A dispute can involve the source or character of income, a residency position or the treatment of a significant transaction. The relevant timeline and records should be developed around the issue identified in the notice.
Business and owner-level adjustments
An entity-level adjustment may affect an owner’s return as well. We examine the relationship between the records, returns and proposed findings so that related positions are considered together.
Penalties and federal adjustments
A California notice may include penalties or relate to a federal tax change. The state response should address the applicable California rules and deadlines rather than assume that the federal response resolves every issue.
FTB Protest and OTA Appeal Are Different Steps
FTB’s published process generally allows 60 days from a Notice of Proposed Assessment to file a protest. If FTB issues a Notice of Action after the protest, the general deadline to appeal that assessment decision to the Office of Tax Appeals is 30 days. Other notices and refund matters can follow different rules. The actual notice and applicable provisions must be reviewed. See FTB’s assessment dispute process.
A protest should identify the challenged findings and explain the supporting facts and legal grounds. An OTA appeal is a separate proceeding with its own submissions and hearing process. A request for assistance or an informal conversation should not be mistaken for the required protest or appeal.
Coordinate the Tax Years, Agencies and Practical Options
A useful strategy addresses more than the disputed total. We review the tax years involved, the relationship to any federal matter, possible interest exposure and what evidence is available. Where a business transaction is involved, the governing agreements and ownership records may be as important as the return itself.
Not every California tax notice is issued by FTB. Sales-and-use-tax and employment-tax matters involve different agencies and procedures. We identify the correct agency and confirm the scope of the engagement before applying an income-tax protest process to a different kind of notice.
A Practical Example
An individual resolves an IRS adjustment and later receives an FTB notice concerning the same transaction. The state matter still requires a review of the California treatment, the notice and its deadline. Copying the federal submission without that review may fail to address the actual state issue.
This hypothetical illustrates an issue; it is not a description of a firm case or result.

Frequently Asked Questions
No. A protest asks FTB to reconsider its proposed assessment. An appeal to the Office of Tax Appeals is a separate administrative review step. The document triggering each procedure, the filing requirements and the deadlines need to be identified individually.
Do not assume that it will. Federal adjustments can affect California reporting, but state treatment and procedural requirements must be evaluated separately. Provide both federal and state notices so that related obligations and response dates can be considered together.
No. A response deadline may arrive before the record is complete. Bring the notice and whatever records are available, and identify the missing materials. Counsel can assess what filing or response is needed while the factual work continues.
