Accounting firm valuation, and how SBA rules change the deal

Published October 25, 2026 · Rules checked against SBA and IRS sources as of October 2026

How retention risk is usually priced

Outside SBA lending, accounting practices are commonly sold on a multiple of annual recurring fees, with part of the price paid over time and adjusted for how many clients actually stay. The logic is sound: a CPA practice's value lives in client relationships, and the seller is best placed to keep them. But that structure is a seller earnout, and SOP 50 10 8.1 prohibits earnouts in SBA change-of-ownership deals. An SBA-financed purchase has to handle retention risk in other ways:

• Price it in up front. The valuation should reflect realistic retention, based on the client list's history, how many clients are tied personally to the seller, and how fees are spread.
• Use a buyer rebate. SBA permits a performance-based rebate from the seller to the buyer, as long as it's applied to pay down the 7(a) loan's principal.
• Plan the handover. A consulting agreement of up to 24 months lets the seller introduce clients through at least one full tax season, ideally two.
• Get a non-compete and non-solicit. They don't make clients stay, but they stop the seller from taking them.

Normalizing the numbers

Seasonality and working capital

Accounting practices collect a large share of their fees in a few months. A buyer closing in late spring may inherit a quiet summer with payroll to meet, and receivables from tax season that belong to the seller under the purchase agreement. The purchase agreement should be explicit about receivables and work in progress at closing, and the lender should consider whether a working capital line or permanent working capital in the loan is needed to bridge the off-season.

What the lender checks

• Fees by client and service line, three years plus the trailing twelve months.
• Client retention history and the share of fees from the top 20 clients.
• Buyer's eligibility to own a CPA firm under state accountancy rules.
• Price fixed at closing, with no earnout; any rebate structured to pay down the loan.
• Transition plan covering at least one tax season.

See SBA earnout rules.

What makes one practice worth more than another

Two practices with the same fees can be worth very different amounts. Value tends to be higher where fees are recurring and spread across many clients, where staff rather than the owner do most of the work and hold the client relationships, where software and workpapers are organized enough to hand over, and where fees have kept pace with the work. It tends to be lower where a few business clients dominate, where the seller personally prepares most returns, or where clients are mostly one-off and price-sensitive.

How the valuation approaches apply

A valuation for an SBA lender considers the income, market and asset approaches. For an accounting practice, the asset approach rarely matters: there are computers, furniture, software licences and perhaps a lease, but almost all the value is client relationships. The income approach, built on normalized cash flow after market pay for the professionals and adjusted for expected retention, usually carries the conclusion. Market evidence from practice sales is often quoted as a share of annual fees, but those figures typically assume retention-based payment terms that an SBA deal can't use, so a valuer has to be careful about applying them to a fixed, all-cash-at-closing price. The standard of value matters here too: fair market value assumes a hypothetical buyer, not one who happens to have spare capacity to absorb the clients.

From normalized cash flow to a loan

Illustration, not a real deal

Continuing the example above, say the lender accepts retained cash flow of about $175,000 as the realistic first-year figure. At SBA's 1.25x coverage minimum, that supports annual debt service of $140,000. At an assumed 10% rate over 10 years, that's a loan of roughly $880,000. Add the buyer's minimum 10% equity on the total project and you have the outline of what the deal can carry. If the seller is asking for a price built on the $310,000 figure, the gap is the retention risk, and it has to be closed by price, more equity, or a buyer rebate that pays down the loan if retention falls short.

Client confidentiality during diligence

Accountants who prepare tax returns are subject to federal limits on disclosing or using taxpayers' return information under Section 7216 of the Internal Revenue Code, as well as professional confidentiality rules. That affects how much client-level detail a seller can hand to a buyer, a lender or a valuer before closing. In practice, diligence often runs on anonymized client lists (fee, service type, years as a client, staff contact) until the deal is far enough along, with any further disclosure handled under the rules and with counsel's advice. Lenders and valuers can work with anonymized data, as long as it ties to the firm's billing records and tax returns.

Reading the client list

The client list is the business, so it deserves more than a total. Useful cuts: fees by client, ranked; years each client has been with the firm; services per client (a client buying tax, bookkeeping and payroll is stickier than a tax-only client); fee changes over three years; and which staff member does the work. Clients served by staff who are staying transfer more easily than clients the seller handles personally. A long tail of small, low-fee returns can look like volume but may cost more to serve than it earns, and a valuer will look at fee per client and realization to see whether that's the case.

Receivables and work in progress at closing

Practices often have significant receivables and unbilled work at any given time, especially around filing deadlines. Asset purchases commonly leave pre-closing receivables with the seller, which means the buyer does the collecting for someone else while waiting for their own billings to turn into cash. Spell out in the purchase agreement who owns receivables and work in progress at closing, how payments that arrive afterward are split, and how that affects working capital in the loan.

How the price is allocated

For tax, nearly all of an accounting practice's price ends up in Class VI and Class VII: the client list and records as customer-based intangibles, any non-compete, and goodwill as the residual. The buyer amortizes those over 15 years. The seller generally prefers goodwill to a non-compete, which is usually ordinary income. See PPA intangible assets.
