About Mark Brumbelow

I help businesses bring clarity to complexity—especially when it comes to corporate tax compliance, income tax reporting, and strategic transactions.With two decades of experience across top 100 accounting firms, I advise companies through the ever-evolving landscape of ASC 740 (FAS 109), FIN 48, and multi-jurisdictional tax compliance. Whether it’s navigating a transaction in the most tax-efficient manner possible, identifying tax credits and incentives for clients serving in multiple jurisdictions, or analyzing uncertain tax positions and income tax provision disclosures needed for financial statements being used to secure financing for succession planning goals, I enjoy being the bridge between technical guidance and practical business outcomes.I’ve worked with clients in healthcare, real estate and development, financial institutions, and manufacturing—helping leadership teams gain confidence in their tax situation and move forward with agility.I’m so proud to rejoin this wonderful team at LBMC—one of the nation’s top advisory and accounting firms—to continue that work with companies that are scaling, evolving, and innovating.Currently, I serve on the AICPA Corporations and Shareholders Technical Resource Panel, where I contribute to national guidance on complex tax policy, compliance, and reporting issues that directly affect the business community.On a personal note, I have deep ties to East Tennessee and a special connection to the Chattanooga area—my wife grew up calling Chattanooga home and we are excited to watch our love for this city germinate and grow for years to come. I look forward to supporting clients throughout the region and beyond.About LBMC in ChattanoogaLBMC is one of the Southeast’s largest accounting and business consulting firms, recognized nationally as a Top 40 firm by Accounting Today, a 2025 USA TODAY Most Recommended Firm, and as a Great Place to Work® recipient five years running.Our Chattanooga office is part of a growing regional team that supports private businesses, high-net-worth families, and industry leaders in healthcare, real estate, technology, manufacturing, financial services, and more.From tax strategy and compliance to assurance, transaction advisory, cybersecurity, AI custom tools/consulting, and outsourced solutions, LBMC brings breadth and depth to every client relationship—grounded in a people-first approach that values clarity, trust, and long-term impact.
