California User of Fuel Bond
Overview
California's fuel tax system depends on self-reporting — and the state requires a surety bond to back that up. If you use diesel, aviation fuel, or another taxable fuel in your operations and report it directly to the California Department of Tax and Fee Administration (CDTFA), this bond guarantees you will pay what you owe. It protects the state's tax revenues against non-payment, underpayment, or default by a registered fuel user. Without it, you cannot legally operate as a licensed user of fuel in California.
Who Needs This Bond?
Businesses that consume taxable fuel in their own operations — and report that usage directly to the CDTFA as a registered fuel user — are the ones who need this bond. Typically, this means companies running fleets, heavy equipment, or industrial machinery on taxable fuel they purchase without tax pre-collected at the pump. If California has assigned you a User of Fuel account and asked for a bond as a condition of that account, you are the principal. This is not a retailer or distributor bond — it is specific to end-use consumers who have elected or been required to report fuel taxes directly.
What is this Bond For?
This bond exists to secure payment of California fuel use taxes that a registered fuel user is obligated to remit. The CDTFA is the obligee — the agency holding the bond and able to make a claim against it. If you fail to pay your fuel taxes when due, the CDTFA can draw on the bond to recover those unpaid taxes. It is a financial guarantee, not liability insurance — it ensures the state gets paid even if your business cannot or does not pay.
When is it Required?
Registering as a User of Fuel with the CDTFA is the moment this bond becomes mandatory. The CDTFA determines the required bond amount based on your estimated fuel tax liability and may require the bond before issuing or maintaining your fuel use account. If your account is already open but the CDTFA has subsequently required a bond — due to a compliance review, a change in your tax exposure, or a prior deficiency — you need to file it promptly to keep your account in good standing. Missing this requirement puts your registration at risk.
Where Does it Apply?
This bond is a California statewide requirement administered by the CDTFA. It applies wherever you operate as a registered fuel user within California's jurisdiction. There is no local or county-level version of this bond — it is governed entirely by state-level fuel tax rules.
