Buying an Accounting or Bookkeeping Practice
Recurring revenue, sticky clients, and a licensing rule that decides what you can own. How accounting, tax, and bookkeeping practices trade, why client retention is the whole deal, and where a non-CPA buyer can and cannot play.
First, the Ownership Rule
Know this before building the thesis: in most states a licensed CPA firm (anything performing attest work such as audits and reviews) must be majority-owned by CPAs, with non-CPA ownership capped at a minority stake under the Uniform Accountancy Act pattern. If you are not a CPA, buying a full CPA firm outright is usually off the table. What is open to any buyer: bookkeeping, payroll, and most tax-preparation practices, which generally require no ownership license. Many searchers structure around the rule by targeting non-attest practices or partnering with a CPA who holds the required stake.
What Practices Trade For
The long-standing rule of thumb is about one times gross revenue, and 2025 marketplace data ran close to it, with reported averages near 1.1x revenue and roughly 2.3x reported earnings. Broker guidance frames the wider band at roughly 2.5x to 3.3x SDE and 1.0x to 1.2x revenue, with advisory-heavy firms at the top and pure compliance shops below. Bookkeeping practices price more reliably on earnings than on the revenue rule, since monthly recurring engagements carry different margins than seasonal tax work.
Retention Is the Deal
The asset you are buying is a client list that can leave. Practice sales are commonly structured with retention protection: an earnout, a clawback, or a holdback tied to how much of the book survives the first year or the first tax season under new ownership. Take that structure seriously rather than negotiating it away for a cleaner headline price. It aligns the seller with the transition, and the transition (introductions, joint meetings, the seller's name on communications for a season) is what keeps the revenue you paid for.
Read the Book of Business
Quality varies enormously between practices with identical revenue. Pull the client list by fee size, service type, and tenure: recurring monthly bookkeeping and retainer advisory work at the top; annual tax returns in the middle; one-off projects at the bottom. Check fee levels against market, since chronically underpriced books built on the seller's loyalty discount churn when repriced. Watch client concentration, client age (a book of retiring owners runs off), and how much work sits in the seller's personal relationships versus the staff's.
What to Verify in Diligence
Beyond the list itself: staff credentials and capacity (who actually prepares the returns and closes the books, what they are paid against market, and who might leave with clients); workflow and software (a practice on modern cloud tooling transfers far more cleanly than one on desktop software and paper); seasonality and the cash-flow shape of a tax-heavy book; work-in-progress and unbilled time at close; and any attest engagements in the mix, which change both the license requirements and the risk profile.
Financeability Notes
Lenders finance these practices regularly: earnings are documented, revenue recurs, and collateral-light service businesses fit SBA 7(a) structures. Expect the lender to focus on retention risk and the transition plan the same way you should, and to look for post-close liquidity through the first tax season, when the retention question gets answered. Model coverage on the book you are confident survives, not the trailing twelve months.
What the Data Says
2025 marketplace benchmarks reported accounting and tax practices at roughly 1.1x revenue and 2.3x reported earnings on average, with the median sale price near $500,000; directional figures from listed-sale data, not comps for any specific practice.

Broker and platform guidance frames typical bands at roughly 2.5x to 3.3x SDE and 1.0x to 1.2x revenue, with advisory-heavy firms at the top of the range and heavy owner dependence discounting the multiple.
Under the Uniform Accountancy Act pattern adopted across nearly every state, licensed CPA firms must keep majority CPA ownership, with non-CPA owners limited to minority stakes and active-participation requirements; non-attest practices such as bookkeeping generally carry no such ownership restriction.
