The big picture
Mercer Advisors' rapid expansion of its tax services demonstrates a broader trend of wealth management firms expanding into adjacent service lines to offer a holistic family office experience. The acquisitions of BFLC and Singer Burke, coupled with organic growth, signal a deliberate strategy to capture a segment of the tax preparation market underserved by both large firms and mass-market providers. This expansion is occurring as many CPA firms seek alternatives to remaining independent, creating a favorable environment for acquisitions.
