Key Takeaways
- • California Franchise Tax Board (FTB) adopted sweeping amendments to sourcing rules for asset management fees effective January 1, 2026, requiring fees to be sourced to California based on investor domicile rather than asset manager location.
- • San Francisco Tax Collector finalized Tax Collector Regulation 2025-1, establishing that asset management fees are subject to San Francisco gross receipts tax if services are provided to investors within city limits, regardless of the asset manager's physical location.
- • Asset managers must now determine beneficial owner domicile when sourcing fees, requiring due diligence through fund structures (e.g., identifying California-based investors in funds of funds) to ensure compliance with both state and local tax requirements.
- • Both regulatory changes represent a significant shift in nexus standards, moving from asset manager location-based sourcing to investor domicile and service location-based sourcing, with potential material tax exposure for firms serving California and San Francisco-based clients.
Summary
The California Franchise Tax Board and San Francisco Tax Collector have both implemented new sourcing rules in 2025 that fundamentally alter how asset management fees are taxed in the state and city. The FTB's amendments to regulation Section 25136-2, effective for tax years beginning January 1, 2026, establish that asset management fees must be sourced to California based exclusively on the domicile of investors receiving services, eliminating the traditional nexus standard tied to the asset manager's operating location. This applies uniformly regardless of whether the asset manager itself operates inside or outside California.
In parallel, the San Francisco Tax Collector finalized Tax Collector Regulation 2025-1, adopting a similar approach for the city's gross receipts tax. The SF Tax Collector's position explicitly states that asset management fees are taxable under San Francisco law whenever services are provided to investors located within city limits, independent of where the asset manager is physically based. This represents a material expansion of tax jurisdiction for San Francisco.
Both regulatory frameworks impose significant compliance burdens on asset managers. Under the FTB regulations, managers must conduct detailed due diligence to identify the domicile of beneficial owners underlying managed assets. This obligation extends through multi-layered fund structures; for instance, an asset manager operating a fund of funds must now determine whether any underlying fund has investors domiciled in California to properly source fees. The San Francisco rule similarly requires managers to identify which clients have nexus to the city. These sourcing determinations directly impact the allocation of taxable income and gross receipts exposure, making accurate investor domicile identification essential for tax compliance and planning.
The convergence of state and local sourcing rules in 2025 signals a shift toward investor-based rather than service provider-based tax jurisdiction, likely increasing compliance complexity and tax liability for multi-jurisdictional asset managers with California and San Francisco-based client bases.
