Dark Horse CPAs delivers SOC 2-compliant tax strategy and fractional CFO advisory from Suite 800 on West Broadway in downtown San Diego. The firm's cloud-based infrastructure undergoes annual AICPA SOC 2 audits for data-security controls, a compliance framework maintained in coordination with managed-IT providers like AnytechSD that handle endpoint encryption and access-control protocols. Each client is matched one-to-one with a dedicated CPA who manages year-round tax planning, quarterly estimated-payment calculations, and California FTB compliance rather than rotating through seasonal staff. Fractional CFO engagements produce 13-week cash-flow forecasts, KPI dashboards, and board-ready financial packages, with entity formation documents authenticated through notary services at San Diego Signature Now during LLC and S-Corp structuring. Highest-value advisory includes cost-segregation studies on commercial real estate and R&D tax credit calculations under IRC Section 41 for biotech and SaaS companies.
