California’s most radical recent tax idea is also its simplest: exempt the first $150,000 of personal income from state income tax and apply a single 8% rate above that. Steve Hilton has built his entire gubernatorial tax agenda around this structure, positioning it as a middle-class affordability reset financed by spending cuts and waste reduction rather than by shifting the burden elsewhere.
At a Glance
- Hilton proposes zero state income tax on the first $150,000 of income and a flat 8% rate on income above that.
- He frames funding through canceling high-speed rail, agency trims, and anti-fraud efforts — not through new taxes.
- The campaign’s own materials anchor the details; major outlets have reported the same core architecture.
- The plan challenges California’s highly progressive, volatile revenue model, where top earners drive receipts.
What Hilton is proposing, in plain terms
Hilton’s campaign puts the policy in unambiguous language: no state income tax on the first $150,000 of income and an 8% flat rate on dollars above that threshold. He has reiterated the same construct across interviews and posts, tying it to a broader “Operation Zero Waste” that he says pays for it without raising other taxes. His town hall messaging and subsequent coverage preserve the same spine: middle-class relief up front; simplicity and a single marginal rate thereafter; and offsets sourced from canceling the state’s high-speed rail project, trimming agencies by roughly 5% for efficiency, and cracking down on Medi-Cal fraud and other waste.
The campaign has acknowledged the magnitude. KCRA reported the plan could reduce available revenues by up to $65 billion on a static basis — before assumed offsets — a figure that helps explain why Hilton’s financing narrative leans heavily on items with outsized political salience and theoretical savings: a marquee megaproject, broad “efficiency” targets, and fraud control programs.
How it would change California’s tax architecture
California’s personal income tax today is steeply progressive, with multiple brackets rising to a top marginal rate of 13.3% when the 1% mental health surcharge on million-dollar-plus incomes applies. The state’s revenue mix depends unusually on top earners’ income and capital gains, which swing with markets and business cycles; analysts across institutions have noted this volatility for years. A 0%/8% design would flatten that structure considerably above the exemption and, just as importantly, remove tax liability entirely for a large swath of filers at or under the threshold. The distributional effect is conceptually straightforward: households whose taxable income falls below $150,000 would see their state income tax eliminated; those above would face an 8% marginal rate rather than the current step-up schedule.
Mechanically, the proposal would require statutory changes to the personal income tax base and rate schedule, coordination with the Franchise Tax Board for implementation, and a transition for withholding tables and estimated payments. The legal drafting question is not exotic — California has repeatedly rewritten rates and brackets — but the revenue substitution and spending control mechanisms would define whether it is sustainable rather than merely legible.
The funding narrative Hilton is offering
Hilton links the tax cut to three buckets of savings. First, ending the high-speed rail project; second, achieving about 5% savings through agency efficiency and overhead reductions; third, accelerating anti-fraud and program integrity efforts within Medi-Cal and potentially other benefit programs. In public remarks and posts, he casts these as a down payment on affordability, an inversion of what he describes as Sacramento’s bias for new spending and complex programs. Reported examples include canceling rail appropriations, tightening administrative bloat, and redirecting funds currently routed through homelessness programs to interventions he argues would be more effective.
Two realities sit behind that narrative. The first is arithmetic: taking tens of billions off the general fund requires recurring savings of a similar order, not one-time lapses. The second is California’s budget mechanics: large capital projects have multi-year commitments; efficiency gains often demand upfront restructuring; and fraud savings yield is stochastic by design — enforcement improves deterrence but does not book neatly like a tax change. Hilton’s case is that these can be transformed into predictable offsets through executive focus and legislative will. News accounts reflect the claim; they do not provide a formal, line-item scoring that closes the gap.
Where the record is firm — and where detail is sparse
The core of the plan is settled in the campaign’s own words: first $150,000 tax-free; 8% above. Axios coverage from the rollout quotes Hilton making it his top priority; local broadcast and print outlets have repeated the same structure in describing his platform. The financing motifs — high-speed rail, 5% trims, fraud crackdowns — recur consistently in reporting and social posts, and the campaign appears comfortable owning the scale by discussing ballpark revenue effects directly.
Two gaps remain in the public-facing materials. First, version control: earlier trail chatter included a $100,000 threshold before the campaign site and newer interviews converged on $150,000. That evolution is not unusual in a campaign, but it makes archival quotes diverge from the current policy card. Second, budgeting specificity: no independent fiscal score or agency-by-agency reduction plan sits in the record set presented here. That does not undercut what the campaign promises; it does explain why independent distributional or revenue modeling would be the next step for any serious legislative pathway.
How this fits California’s long budget history
The proposal lives inside a familiar California tension: progressive rates that concentrate revenue among high earners, and reform movements promising relief funded by waste elimination. Decades of boom-bust cycles have incentivized initiatives to either broaden the base and lower rates or to maintain progressivity while managing volatility. California’s top rates are among the nation’s highest; revenue dependence on capital gains and high-income taxpayers makes the system resilient in booms and painful in bear markets. A large exemption plus a single 8% rate would move the state toward a flatter profile, reduce the number of filers with any liability, and potentially dampen the most extreme top-bracket dependence.
Whether that trade improves fiscal stability is not automatic. Removing liability on the first $150,000 takes a broad slice of receipts off the table. Flattening the top rate from today’s upper-tier schedule to 8% could reduce sensitivity to capital gains if high-income realizations face a lower marginal bite — but it also reduces revenue from the very taxpayers whose incomes have historically backstopped the budget during expansions. That is precisely why the funding mechanics matter as much as the rate card.
CA next Governor?
Xavier Becerra (D) is the clear favorite to be California's next governor. He's up about 22 to 25 points on Republican Steve Hilton in September polls, and he and the outside groups backing him have raised about $49M to Hilton's $19M. Critically, his record… pic.twitter.com/2xqKp8dHHx

What it would take to implement
Two routes exist in practice: legislation through a Democratic-controlled Legislature or a ballot measure rewriting the tax code. Either path would trigger fiscal analysis by nonpartisan staff and the Franchise Tax Board, surfacing distributional tables, multi-year revenue impacts, and implementation timelines. The hardest work would not be drafting the 0%/8% language — it would be converting the savings narrative into appropriations and policy. Canceling high-speed rail demands a wind-down plan and reallocation decisions; 5% efficiency savings require positions and contracts to be cut or reorganized; anti-fraud efforts need statutory authority, data-sharing, and prosecutorial capacity to deliver recurring, auditable returns.
As with all tax restructurings, secondary effects would matter. Interactions with federal deductibility, withholding, estimated payments, and the Alternative Minimum Tax can change realized taxpayer outcomes. Business formation, in- versus out-migration among high earners, and capital gains timing are all responsive to marginal rates, though estimates vary. None of those dynamics changes the core fact pattern: Hilton is campaigning on eliminating state income tax up to $150,000 and charging 8% above that, financed by spending restraint and program integrity efforts — a straightforward proposal set against California’s complex budget reality.
