Selling an accounting practice: what 7216 lets pass to a successor, and what you can license first
On this page
The short answer
Selling an accounting practice moves client relationships to a successor firm, and the tax rules allow that. Under 26 CFR 301.7216-2(n) and (o), a taxpayer list and statistical compilations may be transferred only in conjunction with the sale or other disposition of your tax return preparation business, and the acquirer is bound by the same limits. AICPA ET 1.400.205 adds a written consent process for client files.
None of that reaches an AI data license. An AI developer is not buying your tax practice. What a selling or retiring firm can license is the material it wrote for itself with no client facts in it. Decide that scope in writing before you talk to any buyer of either kind.
Selling an accounting practice in 2026: who is buying
Owner age is driving supply. INSIDE Public Accounting reports, from its 2025 Practice Management Report, that 31% of managing partners are more than 60 years old and only 55% of firms have a written succession plan for their managing partner or CEO (source: INSIDE Public Accounting, Succession planning and generational shifts (Oct 3, 2025)). CPA firm succession planning is still open at almost half of firms.
Buyers have multiplied. DealSeam's tracker, citing CPA Trendlines and Cornerstone, says tracked private equity investments in CPA firms rose from 22 in 2023 to 65 in 2024 and 104 in 2025 (source: DealSeam, Accounting PE roll-up tracker 2026 (updated Jul 28, 2026)). Smaller practices still change hands mostly firm to firm: Accounting Practice Sales says on its homepage that it sold 301 practices in 2025 (source: Accounting Practice Sales, homepage).
Owners also search how much accounting practices sell for. There is no official figure. DealSeam gives a benchmark of about 3x to 6x EBITDA for firms in its data and says smaller firms are often discussed around 1x annual revenue (source: DealSeam, Accounting PE roll-up tracker 2026 (updated Jul 28, 2026)). Treat both as rough market talk. A practice broker who works from closed deals in your region is the right source for your number, and nothing on this page is a valuation.
What 7216 lets transfer when you sell a tax practice
Section 7216 makes it a crime for a return preparer to knowingly or recklessly disclose information furnished for a return, or to use it for anything other than preparing returns (source: 26 U.S.C. 7216 (Cornell LII)). The regulations define tax return information to include anything you derive or generate from it, and statistical compilations even when no taxpayer can be identified (source: 26 CFR 301.7216-1). The sale-of-practice provisions are narrow exceptions inside that rule:
| Provision | What it allows | The limit |
|---|---|---|
| 301.7216-2(n): taxpayer lists | A list of names, mailing and email addresses, phone numbers and a few related items, used to contact those taxpayers about tax matters or to solicit return preparation work | May not be transferred to anyone unless the transfer takes place in conjunction with the sale or other disposition of your tax return preparation business. The acquirer is bound by the same paragraph. |
| 301.7216-2(n): due diligence | A prospective purchaser can review the list before buying | Only under a written agreement that requires confidentiality and expressly prohibits further disclosure or other use. |
| 301.7216-2(o): statistical compilations | Anonymous compilations for internal management of the practice or bona fide tax research | No aggregate figure from fewer than ten returns, no use in marketing, and (o)(2) bars selling or exchanging a compilation for value except with the transfer of assets in a sale of the tax practice. The acquirer inherits the limits. |
| 301.7216-2(p): quality, peer and conflict reviews | Disclosure for a quality or peer review, or a conflict review when a preparer is employed or acquired by another | Information disclosed for these reviews may not be disclosed or used for any other purpose. |
Read together, these let a successor firm take over your tax clients and keep serving them, with the same confidentiality duties you had.
Client files in a CPA firm sale: the AICPA 90-day consent rule
Section 7216 covers tax return information. The AICPA code covers every client file. Its interpretation on transferring files in a sale, ET 1.400.205, says a member who sells all or part of a practice and keeps no ownership should:
- Send each client in the sale a written request for consent to transfer its files to the successor firm, telling the client that consent may be presumed if it does not respond within a period of not less than 90 days, unless law or state board rules prohibit that (source: AICPA Code of Professional Conduct (updated through Sep 2026)).
- Hold the files until consent arrives or the 90 days pass, whichever is shorter, and keep evidence of it.
- Arrange to return records that clients outside the sale are entitled to, under the records request interpretation.
The buyer has a matching duty: an acquiring member should be satisfied that the predecessor's clients consented to the transfer (source: AICPA Code of Professional Conduct (updated through Sep 2026)). And before closing, ET 1.700.050 says a review for a prospective purchase, sale or merger can threaten confidentiality, so you must take appropriate precautions, for example a written confidentiality agreement with the prospective purchaser (source: AICPA Code of Professional Conduct (updated through Sep 2026)). Your state board's rules sit on top of both.
What the consent covers
Why the sale-of-practice provisions do not reach an AI data license
Owners sometimes reason that if a taxpayer list and compilations can be sold with the practice, a de-identified copy of the firm's files can be licensed alongside a sale. The text does not support that reading:
- The transfer has to be part of selling the tax practice. Paragraphs (n) and (o) allow a transfer in conjunction with the sale or other disposition of your tax return preparation business. An AI developer licensing records is not acquiring that business (source: 26 CFR 301.7216-2 (n), (o), (p)).
- The use stays narrow. Even a successor may use a taxpayer list only to contact the taxpayers on it, and paragraph (o)(2) bars selling or exchanging a compilation for value outside a sale of the practice (source: 26 CFR 301.7216-2 (n), (o), (p)).
- Anonymizing does not help. A compilation that cannot identify any taxpayer is still tax return information (source: 26 CFR 301.7216-1).
- Non-tax clients need specific consent. ET 1.700.060 says that using client information for the member's own purposes in a way that may disclose it to others, even without the client being identified, requires the client's specific consent if the information is confidential, and that consent should state the information, the type of recipient and the intended use (source: AICPA Code of Professional Conduct (updated through Sep 2026)).
That is our reading of the text, and it is the screening rule we apply: client data from a selling firm is never part of an introduction we make, before, during or after a sale. The hub guide, can a CPA firm sell data to AI, walks through the consent rules and penalties in full.
What a firm selling its practice can still license
The firm-owned layer is real but small. It is what the firm wrote about how it works, with nothing that needed a client to exist:
- Audit and review programs and checklists the firm wrote, blank
- Month-end close, review and file-naming procedures written in general terms
- Training decks, role guides and onboarding checklists for staff
- Quality management policies and the firm's own risk assessment, without engagement detail
- Blank engagement letter, proposal and workflow templates the firm wrote itself
Each item needs a read before it qualifies. A completed program, a procedure with a worked example from a real client, or a template copied from a software vendor's library is not firm-authored material. Our guide to audit programs, close checklists and SOPs your firm owns goes through each record type and how to clean it.
Some AI data buyers do want this kind of material. One program accepts accounting firms with as few as 10 staff, below its usual floor of 20, and one broker names client onboarding, month-end close, reconciliation and SOPs as what it wants from accounting firms while excluding client books (source: program terms, Regulr buyer directory). Each figure is a program's own advertised term; our buyer directory lists the programs and links to their published terms. At least one broker excludes accounting firms entirely (source: program terms, Regulr buyer directory).
Expect a firm-owned scope to price well below the ranges buyers advertise for whole-company records, such as $100K to $5M, and expect some buyers to pass. Our data value checker shows which factors move a price, and the overview of what accounting firms can license to AI labs shows the kinds of firm records buyers ask about.
Timing: license firm material before the LOI, or leave it to the buyer
Before you sign a letter of intent is usually cleanest. A signed, scoped license is a known contract you can disclose, and the acquirer prices the practice knowing about it. One buyer program says most companies go from first call to being paid in about 2 to 3 months (source: program terms, Regulr buyer directory).
After you sign, expect less room. Letters of intent commonly include exclusivity, and purchase agreements commonly require the practice to run in the ordinary course until closing. Practice purchase agreements often convey the firm's procedures, templates and know-how along with the client relationships, so a new license may need the acquirer's agreement.
After closing, the decision belongs to whoever owns the material under the purchase agreement. If a private equity platform buys the firm, it controls the data decisions from then on.
Exclusivity follows the firm
Retiring from an accounting practice without a buyer
Some owners close rather than sell. ET 1.400.205 asks a member who discontinues a practice without a successor to notify each client in writing and arrange to return the records clients are entitled to. Files for clients you cannot reach should be kept confidential under your retention policy or the applicable legal requirement, whichever is longer (source: AICPA Code of Professional Conduct (updated through Sep 2026)).
The software clock matters too. Drake's 2026 license says that if you do not renew, Drake may revoke web access and has no obligation to store your data, and tells licensees to download it before expiration (source: Drake Software 2026 License and Non-Disclosure Agreement (11(g))). QuickBooks Online gives one year of read-only access after a single subscription is cancelled, and cancels automatically after three failed charges (source: Intuit, Cancel your QuickBooks Online subscription (updated Sep 25, 2026)). Those exports are for record retention and client requests. They are tax return information and client information, not licensing material.
The firm-authored layer lives in the same systems, often as Karbon or Canopy work templates, Ignition proposals and SharePoint folders. Pull it out while subscriptions are live. Our guide to CCH Axcess, UltraTax, Lacerte, Drake and Karbon data terms lists what each vendor's terms say about ownership, export and AI.
Checklist: selling or retiring from an accounting practice
- Decide the path: sale to a successor, merger, private equity, or discontinuing. The tax and AICPA rules differ for each.
- For a sale, plan the ET 1.400.205 client consent letters and the 90-day window into the timeline, and sign a confidentiality agreement with any prospective purchaser before it reviews files.
- Keep anything covered by 301.7216-2(n) and (o) inside the sale of the tax practice. It never goes to an AI buyer.
- Inventory firm-authored material and who wrote it. Separate it from every system that holds client data.
- If you want to license it, write the scope down with named exclusions and do it before the LOI, or with the acquirer's written agreement.
- Compare exclusivity as closely as price, and list any license in your disclosure materials.
- Export everything you must retain before any software subscription lapses.
How Regulr is paid, and how we write these pages
Regulr is a sell-side advisor. When a business we introduce signs a license, we may be paid a fee by the buyer or through a program's referral terms. We list every program we can verify whether or not it pays us, order is never set by fees, and every figure is the company's own advertised term with a link to where it says so. Regulr has not closed a data deal yet, so nothing here describes our results.
Frequently asked questions
Can I sell my clients' tax data when I sell my accounting practice?
Only to the firm that takes over your tax practice, and only within the limits in 26 CFR 301.7216-2. Paragraph (n) lets you transfer a taxpayer list, and paragraph (o) lets you transfer statistical compilations, in conjunction with the sale or other disposition of your tax return preparation business. The acquirer is bound by the same limits. Client files also need the client consent process in AICPA ET 1.400.205.
Does the 7216 sale-of-practice rule let me license client data to an AI company?
No. The transfer provisions in paragraphs (n) and (o) describe a successor taking over your tax return preparation business. An AI developer licensing records is not buying that business, and paragraph (o)(2) bars selling or exchanging a statistical compilation for value except in that kind of transfer. Even a successor may use a taxpayer list only to contact the taxpayers on it.
How much do accounting practices sell for?
There is no official figure. One private equity deal tracker gives a benchmark of about 3x to 6x EBITDA for firms in its data and says smaller firms are often discussed around 1x annual revenue. Practice brokers price from their own closed deals, so ask one for comparables in your region and service mix. A data license is a separate question and does not change those numbers in any way we can claim.
Do I need client consent to transfer files when I sell my CPA firm?
Under AICPA ET 1.400.205, a member who sells all or part of a practice and keeps no ownership should send each affected client a written request for consent to transfer its files. The notice can say consent will be presumed if the client does not respond within at least 90 days, unless law or state board rules prohibit that. Files should not move until consent arrives or the 90 days pass.
Can a prospective buyer of my practice review client files?
Yes, with precautions. AICPA ET 1.700.050 treats a review for a prospective purchase, sale or merger as a review of your practice and says you must take appropriate precautions, such as a written confidentiality agreement, so the prospective purchaser does not disclose confidential client information. The 7216 regulations similarly say due diligence under a written confidentiality agreement is not a transfer of the taxpayer list.
What can a retiring CPA license to AI companies?
Only material the firm wrote for itself that contains no client facts: blank audit programs and checklists, internal close and review procedures written in general terms, training, quality management policies and blank templates. That set is narrower than what buyers usually price, so expect a smaller offer or a decline. Everything built from client work stays out.
Should I license firm material before or after I sell my practice?
Before you sign a letter of intent is usually cleaner, because the license becomes a known, disclosed contract. Practice purchase agreements often convey the firm's procedures, templates and know-how along with client relationships, so after closing the decision may belong to the buyer. Watch exclusivity: one program requires 24 months of seller exclusivity, which would bind the firm under a new owner.
What happens to my tax software data when I close my practice?
It depends on the vendor. Drake's 2026 license says Drake has no obligation to store web-based data if you do not renew and tells licensees to download it before expiration. QuickBooks Online gives one year of read-only access after a single subscription is cancelled. Whatever you export is still tax return information, so it is for record retention, not for licensing.
