Audiocast: Managing FS tax exposure in a shifting California landscape

  • Insight
  • November 13, 2025

California’s shifting tax landscape is raising new implications for financial services companies, particularly around sourcing, conformity updates and wealth-based proposals. In this episode, Caragh DeLuca, PwC’s Financial Services State and Local Tax Leader, sits down with Ben Luedeke, a tax partner with deep experience advising asset managers. Together, they unpack what finalized market-based sourcing regulations mean for managers with California exposure, the ripple effects of California's updated conformity to the Internal Revenue Code, and early signals from a proposed billionaire’s tax. Whether filing in California today or not, this discussion spotlights the need to reassess investor's footprint and reporting strategies now.

Key takeaways

  • Finalized California market-based sourcing regulations require looking through fund structures to the ultimate investor, potentially triggering nexus for managers with no physical presence in California.
  • Bright-line nexus standards may subject firms deriving management fees from California investors to California income tax filing obligations, even if they have no employees or offices in the state.
  • Management fee allocation rules use an asset-based test, which may mismatch economic reality but reflect California's regulatory approach.
  • IRC conformity updates (now as of Jan 1, 2025) still decouple from major IRC provisions, though an inadvertent partnership conformity to IRC §163(j) will require a legislative correction.
  • A proposed billionaire’s tax, while in early stages, signals continued pressure for wealth-based taxation through ballot initiatives.
