Tanner LLC is a leading public accounting and advisory firm headquartered in Utah, with offices in Salt Lake City and Lehi and an additional location in Tempe, Arizona. Recognized as a Top 200 firm by Inside Public Accounting and rooted in roughly eight decades of experience, Tanner employs about 249 professionals, including 23 partners, and serves clients across the Mountain Region, West Coast, nationwide, and internationally. The firm is built on three core service lines. Its tax practice delivers compliance, R&D tax credits, international tax, transfer pricing, and state and local tax through lean, efficient processes. Its assurance practice provides audits and broad coverage backed by deep bench strength. Its advisory practice is the firm's differentiator, spanning transaction advisory (Quality of Earnings, transaction readiness, and M&A tax strategy), outsourced accounting and client advisory services (core accounting and compliance, CFO-level strategic finance, planning, forecasting and operations, and team development and tech enablement), and risk and technology advisory (cybersecurity consulting, IT audit and compliance, penetration testing, cloud FinOps, and AI and business systems advisory). Tanner works alongside CFOs, controllers, founders, and finance leaders, particularly in Utah's Silicon Slopes technology community, serving entrepreneurs, innovators, families, and established organizations. The firm is led by Managing Partner Mark Erickson, CPA, with practice leaders Jodie Hewitson (Tax) and Reed Chase (Audit and Assurance), COO Dan Griffiths, and CFO Crystal Bush. Tanner is a member of Allinial Global, connecting it to more than 270 firms across 112 countries while retaining its independence.
