Baker Tilly US and Moss Adams LLP, two prominent accounting and advisory firms, are in advanced discussions to merge, according to sources familiar with the matter. If finalized, the deal would create a stronger competitor in the mid-tier accounting sector, positioning the combined entity closer in size to industry leaders such as Deloitte, PwC, EY, and KPMG.
The merger would combine Baker Tilly—a top-10 U.S. accounting firm with a strong presence in Chicago—with Moss Adams, a West Coast-based firm known for its expertise in serving clients across technology, financial services, and agriculture. While talks are progressing, the deal has not yet been finalized, and terms remain undisclosed.
Both firms have been exploring growth opportunities amid increasing consolidation in the accounting industry. A merger would allow them to expand their geographic reach, enhance service offerings, and better compete with larger rivals.
Representatives from Baker Tilly and Moss Adams declined to comment.
The potential deal comes as mid-sized accounting firms seek scale to handle rising regulatory demands, technological advancements, and client expectations. Mergers have become a key strategy for firms looking to strengthen their market positions without the conflicts that sometimes arise when joining one of the “Big Four” accounting giants.
If completed, the combined firm would operate under the Baker Tilly brand, though Moss Adams’ strong regional reputation may influence branding decisions in certain markets.
