Overview

Tax Advisory & Planning is the strategic, high-value side of tax: corporate and pass-through structuring, international and cross-border planning, transaction (M&A) tax, estate and gift planning, and specialty credits such as R&D and energy incentives. It is advisory rather than compliance work, sold on partner expertise and outcomes.

This is the margin engine that financial buyers want when they acquire accounting firms, since advisory commands premium pricing and grows faster than commodity return preparation. Engagements mix retainer relationships with episodic, deal- and event-driven projects.
