Who is buying accounting firm businesses?

Private equity entered CPA firms through alternative practice structures, starting with EisnerAmper and TowerBrook in 2021. These platforms and their sponsors announced their deals publicly. Most target larger firms, but several buy smaller practices through their member firms. We documented 6 active acquirers as of September 2026, each linked to a company, sponsor or SEC source.

Read this before you answer a letter

Under the Uniform Accountancy Act model, CPAs must hold a majority of a CPA firm’s ownership, so these deals split the attest firm from the advisory business. A small firm is more likely to sell to a platform’s member firm than to the platform directly.

Platform vs add-on: what it means for price

A platform is the first company a PE firm buys in a trade or region; it is usually larger, keeps its management and is priced at a higher multiple. An add-on is a smaller company bolted onto that platform, typically at a lower multiple, because the buyer is paying for your customers, technicians and location rather than a management team.

If one of these groups contacts you

  1. Do not reply with numbers yet

    Run your own range first with the accounting firm calculator.

  2. Ask what kind of deal it is

    Platform or add-on? How much cash at close, how much rollover equity or earn-out, and what role they expect you to play for how long.

  3. Check who owns the buyer

    The sponsor and when it invested tell you how soon the buyer itself may be sold, which matters if you roll over equity.

  4. Talk to more than one buyer

    A single-bidder process rarely gets the top of the range. Use our unsolicited offer guide and checklist.

Frequently asked questions

Who is buying accounting firm businesses?

We documented 6 active acquirers from primary sources, including Grant Thornton Advisors, Baker Tilly, Citrin Cooperman. The table lists each one’s owner, footprint and latest dated announcement.

Do PE-backed buyers pay more?

For larger companies, usually yes on headline multiple, but more of the price may come as rollover equity or earn-out. Compare cash at close and your required role, not only the multiple.
