Governor Gavin Newsom‘s revised 2026-27 California budget introduces tax policy changes projected to raise approximately $1.3 billion in 2026-27, with revenues growing to $2.5 billion in future years. A centerpiece of these proposals is a permanent cap on business tax credits at $5 million annually or 50% of total tax liability, whichever is greater, generating $850 million in the first year and expanding to $1.8 billion by 2029-30. The budget, announced on May 14, 2026, reflects California’s improved fiscal position following stronger-than-expected capital gains revenue collections.
🔥 Quick Facts
- $1.3 billion in revenue raised through tax proposals in the 2026-27 fiscal year
- $5 million annual cap on business tax credits under permanent limitation
- $850 million in first-year revenue from business credit cap alone
- May 14, 2026 marked the official announcement of the May Revision proposal
California’s Tax Revenue Landscape Improves Significantly
California’s overall tax collections substantially exceeded expectations in 2025-26, providing lawmakers and the Governor with additional fiscal flexibility when crafting the May Revision. The state collected $16.5 billion more in revenue than was originally projected in the January budget proposal, driven primarily by stronger capital gains income from thriving technology and investment sectors. This upside revenue allowed the Governor to propose a balanced 2026-27 budget and address long-standing concerns about business tax credit abuse while also offering targeted relief to small business entities.
The May Revision targets revenue gaps identified in the January forecast while maintaining the state’s $9.7 billion Surplus Holding Account deposit to support future obligations. Critically, California’s tax climate reflects structural challenges: the state relies heavily on high-income taxpayers and capital gains, making revenue volatile and dependent on market conditions. The new tax policies attempt to stabilize revenues through permanent structural changes rather than temporary measures.

Business Credit Caps Target Disproportionate Tax Avoidance
The foremost revenue proposal in the May Revision addresses an ongoing issue: large corporations have historically used business tax credits to reduce or eliminate their state income tax liability. Research and development credits, investment tax credits, and other incentive programs were designed to encourage business activity. However, critics argue that corporations and wealthy entities have deployed these credits in ways unintended by lawmakers, reducing transparency and fairness in the tax system.
Governor Newsom’s proposal permanently limits the amount of business tax credits that can be claimed against a corporation’s and partnerships’ tax liability in a single year. The cap applies at the greater of $5 million per year or 50% of the taxpayer’s total tax liability. This means that while a company generating $500 million in tax liability could still claim $250 million in credits, most mid-sized and smaller businesses remain largely unaffected. Large corporations that have been using credits to approach zero tax liability would face meaningful constraints. The policy previously existed as a temporary measure for 2024-2026, but the new proposal makes the cap permanent and gradually expands its impact.
Revenue Impact and Timeline for Tax Credit Limitation
According to California Budget Center analysis and the Legislative Analyst’s Office, the permanent business credit cap generates distinct revenue impacts across fiscal years. In 2026-27, the cap raises $850 million, its first year of operation. As more taxpayers adjust their tax strategies and planning assumptions crystallize, revenues grow to approximately $1.8 billion annually by 2029-30. The gradual increase reflects timing of how corporations and partnerships claim accumulated credits and adjust long-term tax positions.
| Tax Policy Component | 2026-27 Revenue | Future Annual Revenue (2029-30) |
| Permanent Business Credit Cap ($5M or 50%) | $850 million | $1.8 billion |
| Managed Care Organization (MCO) Tax Renewal | $575 million | $2.3 billion |
| Net Tax Policy Changes | ~$1.3 billion | ~$2.5 billion |
The revenue figures underscore the scale of historical credit usage. A $850 million annual revenue gain from capping business credits indicates that corporations and partnerships have been using credits to avoid paying approximately that amount in state taxes each year. Small business advocates raised concerns about the provision, though the Governor’s office emphasized that the $5 million threshold protects genuine small enterprises while addressing credit abuse by larger entities.
“The governor’s proposed revenue solutions include permanently capping business tax breaks at $5 million or 50% of total tax liability (whichever is greater), providing meaningful revenue while exempting small businesses from meaningful impacts.”

Broader Tax Agenda and Competitive Implications
Newsom’s May Revision pairs the credit cap with other tax provisions designed to modernize California’s revenue system. A proposed digital software tax addresses the tax treatment of subscriptions and software-as-a-service (SaaS) products, an industry category that has grown exponentially while taxed inconsistently. Additionally, the budget includes 50% cut to new LLC formation fees, reducing the first-year filing tax from $800 to $400 for certain entities between 2027-2029, signaling that the administration balances revenue measures with business incentives. The concurrent small business relief demonstrates the administration’s interest in not penalizing entrepreneurship while addressing corporate tax avoidance. As a counterpoint to California tech sector job losses, such relief may help sustain startup formation and small enterprise growth, which remain critical to long-term employment in the state.
What Does This Mean for California’s Long-Term Fiscal Strategy?
California’s budget proposal reflects two competing forces: growing revenue volatility and a need for structural tax fairness. The state’s heavy reliance on capital gains income from stock sales and wealth creation has made budgets vulnerable to market downturns, as experienced during 2022-24 with projections of multi-billion-dollar deficits. By making the business credit cap permanent, policymakers hope to establish a more predictable revenue base that does not depend on market sentiment. The permanent nature of the cap differentiates it from previous temporary credit limitations, signaling legislative commitment to sustained fairness in the corporate tax system. However, California faces ongoing pressure from companies considering relocation to lower-tax states. Whether the credit cap causes material business flight remains uncertain, though business advocacy groups have expressed concern about competitive disadvantage relative to states with more generous tax incentives.
