How to sell an accounting practice

By the accounting8 Editorial Team · Updated · Editorial policy

Selling a CPA firm, tax practice, or bookkeeping business is a nine-step process that takes most of a year, runs on the tax calendar, and is governed by a handful of rules that set the timeline: the 90-day client-consent requirement, the bank's 60 days, and the buyer's need to be in the chair before the next filing season. This guide gives the steps, the season, the deal structures with who bears which risk, the client-file rules for California and the other states, and the tax treatment of the proceeds.

The nine steps

  1. 1.
    Decide what is for sale and when you leave
    The whole practice or a book within it; the office and lease or just the clients; your last filing season; how long you will stay afterwards. Buyers ask these in the first call, and an open-ended answer costs money: brokers list a seller who plans to remain indefinitely among the factors that reduce price.
  2. 2.
    Assemble the numbers
    Three years of profit and loss and tax returns, a fee schedule by client, the top ten clients as a share of fees, staff roles and pay, an inventory of software and files, and an add-back schedule (your compensation, benefits, personal expenses run through the firm) that turns net profit into seller's discretionary earnings. Raise fees to market and clean up receivables in the year before listing.
  3. 3.
    Set a range, not a number
    Small practices sell near one times annual fees and about two times SDE; the valuation guide has the sold data, the broker corridors, and an estimator. Sold listings close at 97% of asking on average, so the asking price does most of the negotiating.
  4. 4.
    Choose the channel
    A specialist broker (seller-paid success fee, rate not published; see the brokers guide), a marketplace or classified listing, or a free blind listing on accounting8. The routes can be combined; watch the exclusivity clause in any broker agreement.
  5. 5.
    Publish a blind profile and qualify buyers
    The profile shows region, fees, mix, staff, and reason for sale, never the firm's name. A buyer signs a confidentiality agreement and shows a credential and financing before seeing the name, the client list, or the financials. Brokers also ask buyers to sign a non-solicit at this stage.
  6. 6.
    Take offers and agree the structure
    Price, cash at closing, any seller note or earn-out, the retention mechanism if there is one, the transition period, the non-compete, what happens to staff and the lease, and the purchase-price allocation. A letter of intent usually fixes these and gives the buyer exclusivity for due diligence; Poe Group Advisors argues for skipping the LOI and going straight to a signed agreement with diligence afterwards.
  7. 7.
    Due diligence and the buyer's financing
    The buyer reviews the client list, workpapers, and financials under the NDA; their lender wants the same package plus the buyer's credit. SBA lenders average about 60 days from application to funding. Tax return information may be reviewed at this stage under a written confidentiality agreement without client consent (§301.7216-2(n)).
  8. 8.
    Sign the asset purchase agreement and close
    The agreement covers payment structure, who collects pre-closing receivables, retention provisions, the non-compete, transition duties, employee terms, representations and warranties, indemnities, closing conditions (lender approval, lease assignment, license transfers), the price allocation for tax, and dispute resolution. Both parties file IRS Form 8594 with their returns.
  9. 9.
    Notify clients and transition
    Send the written consent request to every client whose files transfer, in the form your state board requires, and introduce the buyer in person or jointly by letter. Files of clients who object or cannot be reached stay with you. Brokers' transition expectations range from a few weeks (APS) to a full season; larger deals expect two to three years.

The season and the timeline

Every broker describes the same calendar. Nothing happens between late January and mid-April because both sides are filing returns. Sellers list from late April; ProHorizons puts the window at 1 May to the end of September, ABAG says right after 15 April, and Poe Group Advisors notes buyers are quiet in May and June and very active from August. Most closings fall between September and January because a buyer wants to own the practice before the next season’s fees arrive. A bank-financed deal needs about 60 days from application, so Berkshire’s rule is to be under contract by the end of October to close by year-end, and ProHorizons warns that the odds of a bank-financed close drop after 15 October.

A twelve-month plan, assembled from broker roadmaps (Naab, ProHorizons, Poe) and the rules that set the waits
Months before closingWhat happensWhy then
12–9 (the prior autumn)Clean the client list, raise fees to market, document processes, move files to the cloud, fix concentration where you canBuyers price what they see in the last twelve months of fees
8–5 (winter)Work the season; assemble three years of financials and the add-back schedule while the numbers are freshThe listing goes out with the completed season's fees
4–3 (late April to June)Blind profile live; buyer inquiries, NDAs, qualification; first meetingsBuyers return from the season and lenders are free
3–2 (summer)Offers, structure, letter of intent; buyer applies for financing; due diligence under NDABank needs ~60 days; consent notices can go out once the deal is certain
2–0 (September to January)Purchase agreement, lender approval, lease assignment, closing; client consent letters and introductionsThe buyer is in the chair before the next filing season
After closingTransition period; files of non-responding clients transfer after day 90 of the notice; earn-out or look-back measured over 12–36 monthsAICPA 1.400.205 and California §54.3 set the 90 days; the purchase agreement sets the rest

Deal structures and who carries the retention risk

The price a seller nets depends on the structure more than on the multiple. The structures in use, with the sources that describe each as typical:

StructureHow it worksWho bears client-retention riskWhere it is described as typical
Cash at close, bank-financedBuyer brings an SBA or conventional loan for 70–90% of the price plus 10–15% cash; optional seller note of 10–20%; example $1M = $800K loan + $100K down + $100K noteThe buyer and the bankAPS financing page; Poe: "most of our transactions do not have client retention clauses"
Cash plus earn-out60–80% at closing; 20–40% over two to three years, paid in full if retention stays above 85–90% and scaled down below it; example $1M = $700K at closing + $300K over three years at 90% retentionShared; the seller carries the earn-outNaab Consulting 2026 guide
Seller noteSeller lends part of the price at an agreed rate for two to five years; under SBA rules it counts as equity only on full standby and up to half the injectionThe seller carries credit risk on the noteAPS FAQ; ProHorizons; SOP 50 10 8
Collection pricing (legacy)20% down, then 20% of collections each year for four yearsAlmost entirely the sellerMICPA / APS, Nov 2025; ABAG warns of 3–10-year versions
Look-back pricingFull cash at close, but the seller refunds part if collections fall short at a look-back date, e.g. twelve monthsThe seller, for the look-back periodMICPA / APS, Nov 2025
Gross-revenue guarantee (California)Seller finances part of the price and guarantees the gross revenue transferred, with transitional assistanceThe sellerBusiness Brokerage, Inc.: on every listing
The large specialist brokers say they sell most listings for cash at close with no retention clause; Midwest guidance treats earn-outs as standard; California’s long-standing convention is seller financing with a revenue guarantee. These are regional and broker-model differences, not one market fact. Get the structure, not just the price, into the letter of intent.

The financing the buyer brings

Most individual buyers use an SBA 7(a) loan: up to $5 million, a term of up to ten years (twenty-five when real estate is included), eligible for a complete or partial change of ownership, at a rate set as prime plus a lender margin. Under the SBA’s SOP 50 10 8, effective 1 June 2025, a complete change of ownership needs a 10% equity injection from the buyer; a seller note counts toward it only if it is on full standby for the life of the loan and makes up no more than half of the injection, so a seller cannot lend the buyer the whole down payment. Lenders that specialize in practice loans quote about 60 days from application to funding and often add working capital to cover the seasonal gap. For a seller this means two things: ask early whether the buyer is pre-qualified, and expect the lender to want your three years of financials, your client concentration, and your retention history as much as the buyer does.

Client files and the 90-day rule

A practice is sold by transferring client relationships, and the client owns the relationship. The AICPA Code of Professional Conduct, interpretation 1.400.205 (effective 30 June 2017), requires a member who sells or transfers a practice and keeps no ownership in it to send a written request to each client whose files are subject to the sale, asking for consent to transfer the files and stating that consent may be presumed if the client does not respond within a period of not less than 90 days. No file moves before consent or day 90, whichever comes first; records not sold are returned; files of clients who cannot be reached are retained confidentially; and the acquiring member must be satisfied that the consents were obtained. Verbal consent does not count. A seller who becomes an equity owner of the successor firm is outside the rule; one who stays on as an employee or consultant is not.

California

California made the rule mandatory for every licensee, member or not. Board of Accountancy regulation 16 CCR §54.3, in force since 1 April 2024, requires written notice to each affected client by first-class or certified mail, or by e-mail to an address the client authorized in writing, containing a request for consent and the statement that consent is presumed after 90 days without objection. Records of clients who object are returned without delay; records of clients who cannot be reached are not transferred and are kept for at least four years; the notice and each consent or objection are retained for at least four years after the sale. A California broker’s practice sheet draws the consequence: the closing date may need to sit 90 days after the notices, and some purchase agreements tie part of the price to consenting clients. Brokers report 50–65% of clients respond to the first request.

Florida, Michigan, Delaware

None of the three has a sale-specific board rule that we could find. Florida’s statute makes working papers the CPA’s property (§473.318) and its rule 61H1-23.002 requires client records to be furnished to the client on request; Michigan’s Occupational Code keeps client information confidential without written permission; Delaware’s rules were not retrievable in full. For AICPA members in these states, 1.400.205 is the operative standard; for non-member preparers, the federal rule below and the engagement letter govern.

Tax return information: Treasury Regulation §301.7216-2(n)

Federal law restricts what a tax return preparer may do with return information, and the regulation carves out the sale of the business. A preparer may keep a list of clients (names, addresses, e-mail, phone, entity type, return form number) and may transfer it only in conjunction with the sale or other disposition of the tax return preparation business. Due diligence before a proposed sale counts as being in conjunction with the sale, and is not a transfer, if it is done under a written agreement that requires confidentiality and prohibits any use other than evaluating the purchase. The acquirer inherits the same limits, and paragraph (m) extends the rule to retained returns and records. In practice the seller can open the books to a qualified buyer under NDA without asking each client, and the buyer can use the list to offer tax preparation and nothing else; see the IRS §7216 information center.

Staff, lease, and the non-compete

Buyers of practices under $2 million usually want all of the staff, and brokers treat key staff without non-competes as a negative because a departing employee can take clients. Confirm pay, benefits, and any employment agreements in the purchase agreement, and tell staff late and together. Most buyers keep the location for at least the first year; the lease must be assignable, and long or expensive leases are on every list of value reducers. The seller’s non-compete sets a distance and a term and bars solicitation of former clients; no broker publishes standard years or miles, so it is negotiated with the price. For tax purposes the covenant is a separate asset of the sale (below).

Taxes on the proceeds

The IRS treats the sale of a business as the sale of each of its assets, with the gain or loss on each determined separately; capital assets produce capital gain, depreciable property held over a year falls under section 1231, and inventory produces ordinary income. Buyer and seller must both use the residual method to allocate the price and both file Form 8594 with their returns, and the allocations must match. The form’s classes matter to a practice seller in two places: goodwill and going-concern value are Class VII, and a covenant not to compete entered into with the acquisition is a Class VI section 197 intangible, which the buyer amortizes over fifteen years. Practitioner guidance treats the seller’s receipts for the covenant as ordinary income and receipts for goodwill as capital gain, which is why sellers push allocation toward goodwill and buyers toward the covenant and fixed assets; the IRS pages state the classification, not the seller-side characterization, so confirm it with your own advisor. Where part of the price is paid after the year of sale, Publication 537 allows the installment method, reporting gain as payments arrive on Form 6252. Entity form changes the answer: an asset sale by a C corporation can be taxed at the corporate level and again on distribution, while a partnership interest is generally a capital asset except for unrealized receivables.

This section records what the IRS pages say; it is not tax advice. Have the allocation reviewed before the purchase agreement is signed, because it cannot be changed unilaterally afterwards.

Selling to an employee, a partner, or by merger

An internal transfer skips the marketing but rarely matches an external price: the Journal of Accountancy’s 2014 analysis found external sales usually produce higher prices than internal ownership transfers, and the buyer’s financing is the same SBA loan with the same 10% injection. A merger into a larger firm with a buy-out over time is the structure larger practices use; it is priced on earnings with a two-to-three-year retention agreement, and it is the route through which private-equity platforms acquire firms (see who is buying). A practice continuation agreement, which names a firm to take over if the owner dies or is disabled, is the fallback every sole practitioner should have whichever route they plan.

Frequently asked questions

How long does it take to sell an accounting practice?
Plan on six to twelve months from decision to closing. Brokers say they reach a signed deal in about three months when demand is strong; sold marketplace listings spend a median of 162 days on the market; bank financing adds about 60 days; and the client-consent notice runs 90 days. Most closings land between September and January so the buyer works the next filing season.
When is the best time to sell an accounting practice?
List between late April and September. Buyers are busy from late January to mid-April, active again from late summer, and want to close before the next tax season, so the fourth quarter and January carry most closings. A bank-financed deal needs to be under contract by about the end of October to close by year-end.
Do I have to tell my clients the practice is being sold?
Yes, in writing, and before their files move. The AICPA Code (interpretation 1.400.205) requires a seller who keeps no ownership to send each client a written request for consent to transfer their files and allows consent to be presumed after at least 90 days; California's Board of Accountancy regulation §54.3 makes the same rule mandatory for California licensees, with notice by mail or authorized e-mail and four-year record keeping. Tax return information may be shown to a prospective buyer for due diligence under a written confidentiality agreement without separate client consent (Treas. Reg. §301.7216-2(n)).
What documents does a buyer ask for?
Three years of profit-and-loss statements and tax returns, a client list with fees by client (anonymized until the NDA is signed), the top ten clients as a share of fees, staff roles and pay, software and file inventory, the lease, and an add-back schedule showing owner compensation and personal expenses so the buyer can compute seller's discretionary earnings.
Can I sell only part of my practice?
Yes; partial sales of a bookkeeping book or a tax book are common. Brokers list a partial sale, or a seller who plans to keep working indefinitely, among the factors that reduce the price, because buyers worry about client confusion and competition. A clear boundary (which clients, which services, a non-compete on the rest) fixes most of it.
What happens to my staff?
Buyers of practices under $2 million usually want to keep all of the staff, and brokers list staff without non-competes as a negative because a departing employee can take clients. Employment terms, pay, and any retention bonuses are agreed in the purchase agreement; tell staff late and together, as brokers and the AI-summarized advice both counsel.
