California Budget & Policy Center Urges Corporate Tax Loophole Closures, Sparking Legislative Debate

SACRAMENTO, CA – The California Budget & Policy Center (Budget Center) released a comprehensive four-part series of reports in August 2025, advocating for significant reforms to the state’s corporate tax code, particularly focusing on the closure of key loopholes. These reports, which detail how highly profitable corporations allegedly avoid billions in state taxes, have intensified ongoing legislative discussions, including around proposals such as Senate Bill 1349 (SB 1349), which aims to address these very issues.

The Budget Center’s analysis highlights provisions like the “water’s edge” election, net operating loss deductions, and certain tax credits that allow companies to reduce or entirely erase their state tax bills. One report, specifically titled “Water’s Edge: Closing the Largest Corporate Tax Loophole in California” and authored by senior policy analyst Kayla Kitson, estimates that closing this single loophole alone could generate approximately $3 billion in state revenues annually by preventing multinational corporations from shifting profits offshore.

For small and mid-sized businesses in California, the landscape of corporate taxation is often a source of both opportunity and apprehension. When discussions around closing corporate tax loopholes gain traction, it's natural for business owners to wonder how such changes might ripple through the broader economic environment, even if their own operations aren't directly implicated in these specific multinational tax strategies. Our view at C&S Finance Group LLC is that any substantial shift in the state’s revenue collection approach can lead to unforeseen compliance complexities or competitive adjustments for all businesses. We've seen clients grapple with evolving tax codes, and the key is proactive planning and robust financial oversight.

The Budget Center’s series argues that California has effectively created a two-tiered tax system where working individuals and small businesses often bear a disproportionate share of the tax burden, while some of the wealthiest corporations exploit legal mechanisms to minimize their contributions. The reports specifically call for mandatory worldwide combined reporting to eliminate the state tax benefit of shifting profits abroad, a practice currently allowed under the “water’s edge” election. This method would require corporations to include income from all domestic and foreign affiliates in their total profits before calculating the taxable share for California.

Beyond the “water’s edge” loophole, the Budget Center also pointed to other significant areas of concern. They highlighted how nearly half of all profitable corporations in 2023 paid nothing more than the $800 minimum tax, despite collectively earning $11.7 billion in state profits. To counter this, the reports recommend permanent limits on business tax credits and deductions to ensure a more equitable distribution of the tax burden and to generate revenue for essential public services and infrastructure.

Political figures have also weighed in on the issue. Tom Steyer, for instance, has previously advocated for closing corporate loopholes, including reforming the commercial side of Proposition 13. He argues that this reform would prevent wealthy commercial property owners from avoiding taxes based on current property values, estimating that such avoidance has collectively cost California $243 billion since 2012. Steyer’s plan also included closing the “water’s edge” loophole, asserting that multinational giants use it to hide profits in offshore tax havens, while small California businesses pay taxes on all their earnings. He projected that closing these loopholes could raise $20 billion in new revenue each year to fund education, healthcare, childcare, and home care without impacting working people.

Despite the strong advocacy for these reforms and the potential for substantial revenue generation, skepticism exists regarding the actual fiscal impact. Source 1, dated September 29, 2026, expressed significant doubt that SB 1349, a legislative effort in this direction, would “produce the cornucopia of revenues its sponsors seek.” This perspective underscores the complex debate surrounding the efficacy and practical outcomes of such legislative changes.

The proposed reforms, if enacted, would primarily affect large multinational corporations and wealthy commercial property owners. However, the broader economic implications for California's small and mid-sized businesses could be significant. A more robust state budget, funded by increased corporate contributions, could lead to improved infrastructure, a healthier workforce, and enhanced public services, all of which indirectly benefit the business environment. Conversely, new compliance requirements or changes in the competitive landscape could present challenges that businesses would need to adapt to.

As the legislative session progresses, stakeholders will closely monitor the fate of bills like SB 1349 and any new proposals emerging from the Budget Center’s recommendations. The debate over closing corporate tax loopholes will continue to be a central theme in California’s fiscal policy discussions, with significant implications for the state’s revenue streams and the operational environment for businesses of all sizes.
