What McGuire Sponsel does
McGuire Sponsel is a privately held specialty tax consulting firm founded in 2007 and headquartered in Indianapolis, Indiana, with a national footprint and 51-100 employees. The firm operates as a B2B professional services organization that functions as an extension of CPA firm teams, serving CPA firms, real estate developers and property owners, manufacturing and technology companies, and businesses with international operations or expansion plans. Revenue is generated through project-based engagements across four core service lines: Fixed Asset Services (cost segregation, Section 179D energy deductions, property tax advisory), R&D Tax Credit Services, Global Business Services (IC-DISC, transfer pricing, international compliance, M&A tax advisory), and Location Advisory Services (site selection, incentive negotiation, and compliance management).
The firm's value proposition is built on deep technical expertise in tax law and IRS guidance rather than proprietary technology platforms. Distribution occurs through direct engagement with CPA firm partners, real estate professionals, and enterprise clients, supplemented by the Alliance Network partnership program that connects regional CPA and real estate firms to McGuire Sponsel's specialty capabilities. Marketing relies on content-driven channels including the Let's Talk Tax podcast, CPE-accredited webinars, white papers, case studies, and earned media placements in Forbes and Accounting Today. Pricing is quote-based and not publicly disclosed, consistent with project-based professional services.
The firm has expanded through two disclosed acquisitions — Export Assist (2017) and Align Global Consulting (2020) — both targeting international tax capabilities, and has built out practice leadership across all four service lines with named shareholders leading Fixed Asset Services, R&D Tax Credits, Global Business Services, and Location Advisory. The customer base, evidenced by named testimonial logos including Kernutt Stokes, Sisterson, LBMC PC, Cortland, and Anders, consists of mid-sized regional CPA firms and enterprise real estate operators that engage McGuire Sponsel for specialty tax expertise beyond traditional tax practice scope.
