Who decides a California tax appeal? The post-2017 landscape
Edvin Givargis Published 6 minute read
The short answer
It depends on the tax, and since July 2017 the answer has had four parts. The Franchise Tax Board administers income and franchise tax. The California Department of Tax and Fee Administration administers sales and use tax and most special taxes and fees. The Office of Tax Appeals, an independent tribunal of administrative law judges, hears appeals from both. And the State Board of Equalization survives only for its constitutional remnant: property tax oversight and equalization, state-assessed property, the insurance tax, and the alcoholic beverage tax. Practitioners who left California work before 2017, and out-of-state practitioners raised on older treatises, still send protests and appeals to a Board of Equalization that no longer has jurisdiction over them. The routing matters, because each path has its own deadlines and each deadline is jurisdictional.
What happened in 2017
For over a century, the five-member elected Board of Equalization was both a tax administrator and the appellate body for taxes administered by others, an arrangement with no parallel in any other state. Elected members who decided individual taxpayer appeals also raised campaign funds, intervened in staff operations, and administered the sales and use tax apparatus themselves. After a series of audits and scandals, the Legislature acted in the 2017 budget cycle. Assembly Bill 102, the Taxpayer Transparency and Fairness Act of 2017, was passed in mid-June and signed on June 27, 2017, and it took most of the Board apart with effect from July 1, 2017.
The act did three things. It moved the Board's administrative functions, the sales and use tax, and the special taxes and fees into a new civil-service department, the California Department of Tax and Fee Administration. It created the Office of Tax Appeals as a standalone tribunal, staffed by panels of three administrative law judges with tax experience, to hear the appeals the elected Board formerly heard, beginning January 1, 2018. And it left the Board itself in place with only the duties the California Constitution assigns to it directly, which no statute could remove. A follow-on bill that fall, AB 131, filled in procedural details. The elected Board still exists and its members still stand for election, but for income, franchise, sales, and use tax controversies it is history.
The current map, tax by tax
For income and franchise tax, the Franchise Tax Board audits, proposes assessments, and acts on protests and refund claims, exactly as before 2017. What changed is the next step: an appeal from a Notice of Action on a protest, or from a refund claim denial, now goes to the Office of Tax Appeals. The deadlines carried over from the old Board practice: thirty days from the Notice of Action for a deficiency appeal, ninety days from a denial of a refund claim, and where the Franchise Tax Board simply does not act on a refund claim for six months, the taxpayer may treat the inaction as a deemed denial and appeal at any time until the Board acts.
For sales and use tax and the special taxes and fees, the California Department of Tax and Fee Administration now does everything the old Board's staff did: audits, determinations, petitions for redetermination, and administrative protest hearings culminating in a decision. An appeal from that decision goes to the Office of Tax Appeals within thirty days. The department's own internal process must be exhausted first, and the reorganization did not change the fundamental sales tax discipline that the tax generally must be paid before a refund can be litigated.
The Board of Equalization's remaining jurisdiction is the constitutional core: oversight and equalization of county property tax assessment, assessment of state-assessed property such as railroads and regulated utilities, the tax on insurers, and the alcoholic beverage tax. A practitioner with a centrally assessed property client or an insurance tax matter still appears before the elected Board; everyone else has no business there.
City and county taxes, it should be said, belong to none of these agencies. Local business taxes, transfer taxes, and utility taxes are administered by the enacting city or county, with appeal procedures set by local ordinance, a point covered in the related article on documentary transfer tax.
How the Office of Tax Appeals actually works
The Office of Tax Appeals is headquartered in Sacramento with hearing locations in Sacramento, Fresno, and Los Angeles. Appeals are decided by panels of three administrative law judges, each required to have tax expertise, and every appeal produces a written opinion. Opinions may be designated as precedential, and precedential opinions bind the agencies in later disputes, which over eight years has begun to build a genuine body of independent California tax adjudication, including decisions rejecting Franchise Tax Board positions. Hearings are optional; a taxpayer may elect an oral hearing, which is public, or submit the appeal on the written record. Representation is open: an appeal may be presented by an attorney, an accountant, an enrolled agent, or any other person the taxpayer authorizes, and the taxpayer may of course appear alone. A Small Case Program offers a streamlined, accelerated process for appeals below a specified dollar threshold.
Losing at the Office of Tax Appeals is not the end. Either the taxpayer or, in limited circumstances, the agency may petition for rehearing within thirty days of the opinion. After that, the paths diverge by tax. An income or franchise tax matter moves to superior court only as a refund action: the tax must be paid and a suit for refund filed, where the case is heard fresh, without deference to the administrative result. Sales and use tax follows the same pay-first refund litigation model. There is no direct judicial appeal of an Office of Tax Appeals opinion in the administrative mandamus style, which makes the administrative record and the decision to stop or continue at each stage a genuine strategic fork.
Practice notes
The routing errors this architecture invites are all avoidable. Correspondence styled to the Board of Equalization for an income or sales tax matter is the classic one; the agencies forward what they can, but a jurisdictional deadline does not wait for forwarding, and a thirty-day appeal window spent in the wrong mailroom is gone. The reverse error also appears: assuming the Office of Tax Appeals can hear a property tax or local tax dispute it has no jurisdiction over. Second, the deadlines deserve respect precisely because they look familiar: thirty days from a Notice of Action arrives fast, and the ninety-day refund denial window is measured from the denial notice, not from when the file surfaces. The deemed denial rule is the useful pressure valve; six months of Franchise Tax Board silence on a refund claim opens the door to the Office of Tax Appeals without waiting further. Third, the tribunal's independence has real strategic weight. The old Board was a political body; the current panels write reasoned opinions and have shown willingness to part with agency legal rulings, so an appeal that would once have been a formality on the way to court is now a forum where a well-built technical case can actually win, at no filing cost and without paying the assessment first. That combination, free, no prepayment, and a fresh three-judge look, makes the decision to skip the administrative appeal and head for refund litigation one that should be made deliberately, not by default.
