Our Story

Founded in 2007, McGuire Sponsel started as a trusted advisor to local and regional CPA firms. Specializing from the beginning in R&D Tax Credits and Cost Segregation Studies, the founding vision was to position our team as an extension of CPA firms by serving their clients with specialized tax services. Over the years, our services have grown to include Energy Efficient Tax Programs, Global Business, and Location Advisory. With employees spread amongst offices in Atlanta, Dallas, Indianapolis, and Phoenix, we are committed to the CPA industry and continue to provide dynamic and responsive service to our network of more than 450 CPA firms across the country.

Our Commitment to the CPA Industry

The vision cast in 2007 is not different than our vision today. As the industry faces headwinds from all directions, McGuire Sponsel has been a bedrock as firms continue to serve clients and attract new business. Many of our alliance firms are or have been affiliated with prominent international affiliations that offer many services similar to ours. While we do not look to interfere with these organizations, our team strives to be a proactive and chosen alternative with a tailored approach built to complement CPA-client relationships. Above all, we are honored to be an industry leading technical resource to CPA firms and are proud knowing our approach places the highest value on relationships as we partner with CPAs across the industry to deliver proven solutions to your clients.
