AB 1268 adds a new, conditional executive power to the Motor Vehicle Fuel Tax Law: for rate adjustments scheduled on or after July 1, 2026, the Governor may suspend the annual CPI increase to state fuel excise taxes after concluding the increase would impose an “undue burden” on low‑ and middle‑income families. The bill sets a narrow procedural timeline for that suspension — a January 10 notice to the Legislature and a Department of Finance funding proposal — and requires the Governor’s proclamation to follow at least 30 days later.
The change interrupts an automatic inflation-indexing mechanism that transportation agencies and local jurisdictions rely on for predictable revenue. At the same time, it forces the executive branch to identify an alternate way to produce the same level of transportation funding if the adjustment is suspended, creating administrative and fiscal trade-offs between near-term affordability and long-term project finance stability.
At a Glance
What It Does
Starting with adjustments scheduled on or after July 1, 2026, the bill authorizes the Governor to suspend the annual CPI-based increase to fuel excise taxes when the Governor determines the increase would unduly burden low- and middle-income families. The Department of Finance must provide the Legislature, by January 10 of the relevant year, a proposal to retain the same level of transportation funding if the Governor intends to suspend the adjustment.
Who It Affects
State and local transportation agencies, transit operators, and projects that depend on predictable fuel-tax revenues would face revenue-planning uncertainty; motorists and households may see lower fuel costs in suspension years; the Governor and Department of Finance gain new fiscal discretion and administrative duties under tight deadlines.
Why It Matters
The bill replaces part of a mechanical indexing rule with discretionary executive relief tied to an affordability finding and a mandatory funding-replacement proposal, shifting risk from consumers to transportation budgets and centralizing a fiscal decision in the Governor’s office without requiring legislative approval to suspend the increase.

What This Bill Actually Does
AB 1268 modifies the Motor Vehicle Fuel Tax Law’s CPI indexing clause by giving the Governor conditional authority to halt the annual inflation adjustment to state fuel excise taxes for adjustments scheduled on or after July 1, 2026. The bill keeps the underlying tax structure intact — the statutory base cents-per-gallon rates remain in place — but inserts an executive check on the automatic increases that otherwise would rise each July 1 in line with the California Consumer Price Index.
If the Governor intends to suspend a scheduled adjustment, the bill requires two specific administrative steps early in the year: notify the Legislature by January 10 of the intent to suspend, and have the Department of Finance submit by that same date a proposal that would preserve the same level of transportation funding the CPI increase would have generated. The Governor’s final proclamation suspending the adjustment cannot occur until at least 30 days after the Legislature receives the notice, giving a brief window for legislative scrutiny though not a veto or approval requirement.Practically, the statute forces the executive branch to confront the fiscal consequences of a suspension immediately: the Department of Finance must outline how to replace the foregone revenue.
The bill does not prescribe allowable replacement sources or require legislative assent to the replacement plan; it simply mandates that a plan accompany the notice of intent. That leaves multiple possible execution paths — transfers from the General Fund, reallocation within transportation budgets, borrowing, or shortcuts like deferring projects — but it also leaves unresolved accountability and legal complexity around how the replacement is implemented.By converting an automatic, actuarial-style adjustment into a discretionary executive action tied to an undefined “undue burden” standard, AB 1268 alters the predictability of fuel-tax receipts.
Agencies that budget multi-year projects, transit operators with operating subsidies tied to fuel excise receipts, and bondholders relying on projected growth in fuel-tax revenues will need to rethink forecasting, risk allocation, and contingency plans for years where the Governor exercises the suspension power.
The Five Things You Need to Know
The law preserves the existing per‑gallon statutory rates (for example, an 18¢ base rate and the historical supplemental levies) but allows suspension only of the CPI-based annual adjustments that apply to those rates.
Suspensions apply only to adjustments scheduled on or after July 1, 2026, not to earlier CPI increases.
The Governor must notify the Legislature of intent to suspend by January 10 of the year the adjustment would take effect and the Department of Finance must submit a proposal by that same date to keep transportation funding at the originally projected level.
The Governor’s proclamation to suspend may not be issued until at least 30 days after the Legislature receives the January 10 notification, creating a minimum review window.
The bill requires a funding-replacement proposal but does not specify permitted sources or require legislative approval to implement the suspension or the replacement funding.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Base federal-linked excise rate and exemptions
This subdivision restates the core per-gallon tax structure — including the 18¢ base rate and a federal-linkage clause that recalculates the state rate if the federal fuel tax changes — and preserves any existing federal exemptions at the state level. For practitioners, this means AB 1268 does not alter who is taxed or the base calculation mechanics; its intervention point is the later CPI adjustment process.
Supplemental rate tied to a prior exemption (historical mechanism)
Subdivision (b) covers a 17.3¢ per-gallon component originally intended to offset revenue losses from a specified exemption and describes an administrative adjustment procedure that was in force through 2019. That text remains relevant because AB 1268 treats all such enacted increases as part of the ‘base’ subject to future CPI indexing or potential suspension, thereby folding past legislative rate changes into the indexing universe.
Additional statutory levy (12¢) retained
Subdivision (c) records an additional 12¢ per-gallon levy enacted in 2017. AB 1268 does not repeal or change this charge; rather, it preserves it as one of the components that undergoes CPI adjustments and, therefore, may be affected if the Governor suspends the indexing in later years.
Annual CPI adjustment mechanism
This paragraph is the automatic indexing rule: starting July 1, 2020, and each July 1 thereafter, the department increases the taxes imposed under (a), (b), and (c) by the change in the California CPI, rounded to the nearest tenth of a cent. The statute centralizes responsibility for the calculation with the Department of Finance (or the named department), and it ties the timing and rounding rules to specific November-to-November CPI measurements.
Governor’s suspension power and procedural deadlines
This is the operative change AB 1268 makes: for adjustments scheduled on or after July 1, 2026, the Governor may suspend the annual CPI increase after determining the adjustment would impose an undue burden on low- and middle-income families. The paragraph prescribes a procedural sequence — January 10 legislative notice of intent, a January 10 Department of Finance proposal to maintain funding, and a proclamation that may not be issued until at least 30 days after notice — but it does not define “undue burden” or require legislative concurrence to effect the suspension.
Treatment of subsequent legislative increases as base rates
This clause instructs that any post‑2017 legislative increases count as changes to the base rate for CPI calculation purposes. Practically, that means future CPI adjustments will compound on top of any later statutory increases unless suspended under the new (d)(2) authority, expanding the universe of revenue streams subject to the Governor’s discretion.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Low‑ and middle‑income households — If the Governor suspends an increase, those families face lower immediate pump prices and smaller budgetary pressure from fuel costs in the affected year.
- Motor carriers and fuel‑intensive small businesses — A suspended adjustment reduces operating cost growth for businesses whose margins are sensitive to fuel prices, at least in the short term.
- The Governor’s office — Executive branch gains clearer, statutory discretion to respond to affordability concerns without needing new legislation.
- Short‑term gasoline consumers and political constituencies opposed to automatic tax increases — They gain relief and the political advantage of an administratively available remedy.
Who Bears the Cost
- State and local transportation agencies and transit operators — They lose indexing predictability and may face a revenue shortfall in suspension years unless the replacement plan is implemented, putting projects and operations at risk.
- Bondholders and long‑term contractors — Revenue uncertainty can affect debt service coverage assumptions and project cash flows, increasing financing costs or requiring covenant waivers.
- California taxpayers or the General Fund — If the Department of Finance’s proposal relies on transfers or borrowing to replace fuel tax receipts, other programs or future budgets could absorb the cost.
- Department of Finance and the Governor’s administration — They acquire new analytical and implementation burdens on a compressed January timeline and bear political and legal exposure for the replacement plan they propose.
Key Issues
The Core Tension
The core dilemma is between short‑term affordability and long‑term revenue predictability: the bill empowers the Governor to protect households from an inflation‑driven fuel tax increase but, in doing so, shifts financial risk onto transportation budgets, bondholders, and taxpayers who may ultimately be asked to replace lost revenue or accept delayed projects.
AB 1268 creates three main implementation questions that the bill leaves unresolved. First, the statutory trigger—an executive determination that an adjustment would impose an “undue burden on low‑income and middle‑class families”—is undefined.
That leaves unclear what metrics, thresholds, or analytic methods the Governor and Department of Finance must use to reach the finding, and it invites disputes about arbitrariness or unequal application across different regions and fuel markets.
Second, the bill requires the Department of Finance to propose a way to maintain the same level of transportation funding but does not constrain acceptable approaches. The proposal could recommend General Fund transfers, intra‑transportation reallocation, short‑term borrowing, or project deferrals.
Each choice has different legal, fiscal, and political consequences (affecting bond covenants, federal matching formulas, and elected local priorities) and the statute creates no formal approval pathway or timeline for Congress-like deliberation beyond a 30‑day window before the proclamation.
Third, substituting discretionary suspensions for predictable indexing introduces recurring planning risk for agencies and investors. Even if the Governor uses the suspension sparingly, the mere availability of the power can raise project financing costs and complicate long‑range capital and operating plans.
The bill therefore trades consumer affordability in certain years for increased fiscal and administrative complexity across the transportation sector.
