# Buying an Accounting or Bookkeeping Practice

The CPA ownership rule decides who can buy at all. What practices trade for, why client retention is the whole deal, and how to read the book of business.

## 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](https://searchspheresource.com/glossary/searcher) structure around the rule by targeting non-attest practices or partnering with a CPA who holds the required stake.

## What Practices Trade For

BizBuySell's sold accounting and tax practices put half the market between 1.61x and 2.66x [SDE](https://searchspheresource.com/glossary/sde) across 2021 to 2025, with a 2.04x median, on a $425,000 median sale price. [Revenue multiples](https://searchspheresource.com/glossary/gross-revenue-multiple) run 0.92x to 1.17x with a 1.02x median, so the long-standing one-times-revenue rule of thumb sits near the middle of the sold market rather than acting as a floor. 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, which is why practice sales carry retention protection: an [earnout](https://searchspheresource.com/glossary/earnout), a [clawback](https://searchspheresource.com/glossary/clawback), or a holdback tied to how much of the book survives the first tax season. Take that seriously rather than trading it for a cleaner headline price. One professional rule sets the calendar and few buyers know it. On a sale, the seller must write to every client asking consent to transfer their files, may presume consent only after not less than ninety days, and must not move the files before then. An [asset purchase](https://searchspheresource.com/glossary/asset-vs-stock-sale) buys a ninety-day client-notification event, which is when clients shop. Buying the firm moves no files and starts no clock.

## 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](https://searchspheresource.com/glossary/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](https://searchspheresource.com/glossary/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:

## Financeability Notes

Collateral is at its thinnest here: a client list and working papers count for nothing toward the secured test and receivables at a tenth of book, so the shortfall reaches personal real estate by construction. Know which of the two businesses you are buying, too. Federal figures put a CPA office near $244,000 of revenue per employee against $104,000 at a bookkeeping shop, ten points apart on payroll share, so one blended benchmark describes neither. 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](https://searchspheresource.com/glossary/ttm).

## Terms in This Industry

- **Seasonal concentration**: How much of the year's fee income arrives in the weeks around a filing deadline. A practice earning most of its money in ten weeks is a different business from one on monthly retainers, and it is priced differently for good reason. The compressed one needs seasonal staff, carries the whole year's risk in one quarter, and gives a new owner almost no time to fix a problem. Ask for fees by month for three years and read the flat months, because that is the part that survives a bad season.
- **Attest work**: The engagements where a CPA formally vouches for financial statements, which only a CPA firm may do. This is why the ownership rule bites: a firm doing audits or reviews has to be majority CPA-owned, which narrows the buyer pool and shapes how a non-CPA buyer can structure anything. Check what share of revenue is actually attest, because a practice that is mostly tax and advisory with a small audit tail has options a true audit firm does not, including dropping or selling the attest work to clear the path. Dropping it clears the path only if the firm also drops the CPA title, since the model act requires a firm permit for either.
- **CPA-ownership rule**: State rules that a CPA firm be majority-owned by licensed CPAs, which limits who can buy one. It is the ownership wall of the trade. A non-CPA buyer typically needs a licensed partner or an alternative-practice structure, so read the state's own rule before writing an LOI rather than after. The rules vary more than people expect, and the workable structures are known ones with known costs. What you cannot do is discover this in underwriting, because the fix is a partner, and finding the right one takes longer than a diligence window.
- **Realization rate**: What a practice actually collects against the standard rate for the hours it worked. Two practices with identical billings can be very different businesses, because one writes off a fifth of its time before the invoice goes out and calls it client service. The write-down usually sits with a small number of long-standing clients the owner will not reprice. Ask for realization by client and by partner, and treat the worst decile as the first thing a new owner has to decide about.
- **Practice sale disclosure**: Federal rules let a client list move with a practice sale and keep most of the rest behind written consent. The federal floor has its own sale clause: a preparer may hand over a list of client names, contact details, entity types and return form numbers with the business, and diligence on that list runs under a written confidentiality agreement. Most of the rest of a tax file needs the client's written consent. California forbids disclosing confidential client information without the client's written permission, then carves out one path for a sale, which is a written nondisclosure agreement between the two firms covering everything shared. Washington's board allows the same review and attaches no condition of its own, though the federal confidentiality agreement still governs the list, so the gate is a state question before it is a deal question. Sign the nondisclosure agreement before a single file moves, keep a record of what was shared, and read the state's own rule instead of assuming diligence works the way it does in an unregulated trade.
- **Peer review**: The outside inspection a firm doing attest work has to be enrolled in, on a cycle. The word is enrolled, not passed. Florida requires a firm practicing public accounting to be enrolled in a peer review program and excepts compilations and reviews from that duty, and Minnesota conditions the renewal of a firm permit on undergoing a review no more often than once every three years. Neither report is public. Florida makes a review committee's records privileged against discovery, subpoena and even a state accountancy board proceeding, and Minnesota requires the process be run so that neither the board nor any third party can reach the documents. There is nothing here for a buyer to look up: ask the seller for the last report and the date the next one falls due, and read the refusal as the finding. What a change of ownership threatens is the permit itself. Minnesota says a firm knocked out of compliance by a change in owners has to cure it or face suspension or revocation, and both states want the new names filed inside a month.
- **Gross fee penalty**: A penalty on the firm itself, capped at every dollar the offending work earned it. Realization asks how much of the standard rate a practice collects. Its twin asks how much of what it collected can be taken back, and the ceiling is all of it: Treasury's practice rules cap a monetary penalty at the gross income derived from the conduct that gave rise to it. The penalty can run against the firm and not only the person, on a knew-or-should-have-known standard, so it travels with the entity in a share purchase and is measured by fees banked and distributed years ago. The commonest trigger is a fee that was not flat or hourly, because those rules bar a contingent fee for work before the tax authority and define one to include a percentage of a refund or of taxes saved. Ask for every engagement letter whose fee was neither, across three years.
- **Write-up work**: Bookkeeping and compilation billed monthly, which is the recurring half of a small practice's fees. Write-up work transfers far better than tax returns do, because the client has already accepted that staff and not the principal does it. It also prices differently: a practice that is mostly write-up sells on a recurring base, and one that is mostly seasonal returns sells on a relationship the buyer has to earn twice. Ask for fees split into write-up, tax and any attest work, by client. The mix decides both the multiple and how much of the first year goes on keeping clients instead of serving them.

## 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.

- BizBuySell's sold accounting and tax practices put half the market between 1.61x and 2.66x SDE across 2021 to 2025, with a 2.04x median, on a $425,000 median sale price and $208,303 of median owner earnings. Revenue multiples run 0.92x to 1.17x with a 1.02x median, so the widely quoted one-times-revenue rule of thumb is close to the middle rather than a floor.

## How Big This Market Is

There are about 55,052 businesses in this industry. 18,609 of them (34%) have 5 to 99 employees: the band big enough to have something to sell, small enough to finance. Most of the rest are owner-operators with a job rather than a business to hand over. Census County Business Patterns (2023); how often they change hands is on https://searchspheresource.com/data/market-depth.

## Who the Law Lets Own This

CPA firms that perform attest work or use the CPA title must keep majority CPA ownership in nearly every state.

How buyers structure around it: Non-CPAs buy non-attest practices (bookkeeping, most tax prep) or partner with a CPA majority owner.

Most of these rules are set state by state and change, so confirm the current one with the regulator that issues it and an attorney (https://searchspheresource.com/data/license-rules).

## What It Costs to Replace the Owner

A multiple quoted on SDE adds the owner's pay back into earnings, so it holds only if you do the owner's job. For this trade the replacement is usually the office manager who runs the back office, paid a median of $69,500 a year nationally; at a 3x multiple that wage takes about $208,500 off what the business is worth to you. First-line supervisors of office and administrative support workers, BLS Occupational Employment and Wage Statistics (2025), national, all industries, before payroll taxes and benefits (https://searchspheresource.com/data/manager-wages).

## The Numbers That Run This Business
