An accounting practice is valued on its recurring client revenue, and the main question every buyer asks is how much of that revenue will stay after you leave. For that reason, most CPA and bookkeeping practice sales tie part of the price to client retention, paid over one to five years. Who can buy also matters: state rules on CPA firm ownership shape whether a private equity firm, a larger firm or an individual practitioner is the right fit.
Key points
- Small practices often sell for around one times annual gross revenue, with published ranges of roughly 0.75 to 1.5 times. These are broker-reported averages, not guarantees.
- Retention clauses, holdbacks and earn-outs are standard. Read how "retained revenue" is defined before you sign.
- Recurring monthly bookkeeping, payroll and advisory work is usually worth more than once-a-year tax returns.
- Ethics rules allow buyers to review client data under confidentiality, but transferring files and tax information after closing has its own rules.
- Majority CPA ownership requirements in most states shape how private equity deals are structured.
Who buys accounting practices
The general sale process is covered in our business sale guide. In accounting, buyers fall into a few groups.
Individual practitioners and small firms
A sole practitioner or small firm buying a book of clients is the traditional buyer. These buyers often pay over time out of collections, sometimes with a modest down payment. The seller makes introductions during a busy season and then steps back.
Regional and national firms
Larger firms acquire smaller practices to add clients, staff and specialties, or as a succession plan for an aging partner group. These deals are often structured as mergers, with the selling partners joining the larger firm and receiving retirement or buyout payments over time.
Private equity backed firms
Private equity investment in accounting firms has grown quickly. Because state laws require CPAs to hold a majority of a licensed CPA firm, these deals usually use an alternative practice structure: investors buy the tax, advisory and consulting business, while a separate CPA-owned firm keeps the audit and attest work. The National Association of State Boards of Accountancy formed a task force on private equity in the profession and released a white paper for comment in October 2025. Rules in this area are still developing, and some states have stricter ownership requirements than others.
How practices are valued
Multiples of revenue
Accounting practices are one of the few markets where revenue multiples still dominate. The long-running rule of thumb is about one times gross fees. Published ranges from brokers and industry writers generally fall between about 0.75 and 1.5 times annual revenue for small practices, and some data shows completed sales landing below asking prices. Many of these figures come from firms that broker or finance practice sales, so treat them as rough benchmarks.
Larger firms and private equity buyers more often price on EBITDA, after paying market salaries to the partners who stay. Those deals can look very different from a small book sale, and the cash at closing may be a smaller share of the total.
What moves value up or down
- Recurring revenue: monthly bookkeeping, payroll, CFO services and advisory retainers are worth more than seasonal tax work
- Fee levels compared with the local market, and how recently fees were raised
- Client concentration: one client above about a quarter of revenue can lead buyers to adjust the price
- Client age and type: a book of retirees filing simple returns will shrink faster than a book of growing businesses
- Staff who will stay, especially credentialed staff who handle client relationships
- Technology, cloud workflows and documented processes
- Niche expertise, such as construction contractors, health care practices or manufacturers
If your client base is concentrated in one industry, buyers who serve that industry may pay more. Practices that serve trade contractors or manufacturers, for example, often know those clients' own succession plans, which affects how long the relationships will last.
Retention clauses, holdbacks and earn-outs
Retention terms are where most practice sale disputes happen. A typical structure pays a portion at closing and the rest over time, with the total adjusted for client retention. Broker sources describe holdbacks of about 20 to 40 percent of the price tied to retention over two to three years, and payment plans of three to five years in some deals.
Questions to settle in writing:
- Is retention measured by number of clients or by revenue? Revenue is more common and usually fairer.
- Which period sets the starting number, and does it include one-time projects?
- If the buyer raises prices, does the extra revenue count toward retention? Sellers usually want it to.
- Does a client who dies, sells their business or moves count against the seller? What about a client the buyer chooses to drop?
- If the buyer sells added services to your clients, does that revenue count?
- What happens to payments if the buyer sells the practice, merges or stops paying?
Earn-outs in larger deals work similarly but are often tied to EBITDA or revenue growth. Our guide to insurance agency sales covers retention-based pricing in a market that faces the same question of whether clients follow the new owner.
Confidentiality and client files
Accountants hold sensitive information, and three sets of rules apply in a sale.
The AICPA Code of Professional Conduct allows a member to share client information with a prospective buyer reviewing the practice without client consent, provided the buyer agrees not to disclose it. The safeguards were expanded in 2016 to cover information obtained through an actual acquisition. Use a written confidentiality agreement and limit what you share until a buyer is serious.
Transferring client files after the sale is treated separately. AICPA guidance and many state board rules address what notice or consent is needed before files and confidential information move to a new firm. Many sellers send a letter introducing the buyer and asking clients to consent to the transfer.
Federal law adds a layer for tax work. Internal Revenue Code section 7216 restricts how tax return preparers use and disclose tax return information, and its regulations include specific provisions for transfers made as part of the sale of a tax preparation business (26 CFR 301.7216-2). Have counsel confirm that your process fits these rules, especially if your files include data for clients in several states.
Ownership and licensing rules
Most state accountancy laws follow the Uniform Accountancy Act, which requires a majority of a CPA firm's ownership, by financial interest and voting rights, to be held by licensees. Some states are stricter. Non-CPA owners usually have to be active in the firm. A buyer who is not a CPA can generally buy a bookkeeping or tax preparation business, but cannot hold a CPA firm license or use the CPA title.
Check firm registration requirements in each state where you have clients. A change in ownership can require notice to the state board or a new firm permit. Your professional liability coverage also needs attention: on a claims-made policy, sellers usually buy an extended reporting endorsement (tail coverage) to cover claims about work done before the sale.
Bookkeeping practices
Bookkeeping firms sell much like accounting practices, with two differences. Revenue is usually monthly and recurring, which buyers like, and the work is less dependent on a licensed professional, which widens the buyer pool. On the other hand, bookkeeping clients can switch providers easily, so retention clauses are still common. Buyers will look at the software your clients use, how many clients are on fixed monthly fees and how much client contact your staff already handle.
Taxes
Most of the price in a practice sale is goodwill, which can qualify for capital gains treatment. Payments structured as consulting fees or employment pay are ordinary income. Installment payments spread the tax over several years. Some sellers have personal goodwill, tied to their own relationships, that can be sold separately from the firm's goodwill with different tax results. A CPA who does not have a stake in the deal should review the structure.
Preparing to sell
Start two to five years before you want to leave. Raise fees to market levels, move clients to recurring engagements, bring in a manager or partner whom clients already know, and document your workflows. Trim clients who are unprofitable or hard to work with. Buyers pay for a book they can keep.
Health care owners face a similar retention question when they sell, and our guide to medical and dental practice sales explains how DSOs and private equity groups structure those deals with rollover equity and employment terms.
For a practice valuation and confidential buyer search, an accounting practice broker can compare offers from individual buyers, larger firms and private equity backed groups, including how much of each offer depends on retention. Our guide to selling a business explains how to compare cash at closing with deferred payments.
Accountancy rules, ethics interpretations and tax law change, and each state board sets its own requirements. A lawyer licensed in your state and familiar with professional practice sales should review your agreement before you sign.
