Can accounting firms sell anonymized data?
Not as a simple yes. If the material is confidential client information, the AICPA Code generally still requires the client's specific consent, even when names are removed. If it is tax return information, IRC 7216 may also apply. Calling a set anonymous does not, by itself, close those issues.
The Journal of Accountancy is direct on this: do not treat redaction, or a buyer's anonymous-data label, as permission to sell, give, or share the information for model training. See Asked to sell firm data for AI training? Be very cautious (Nov. 2, 2026).
Why isn't removing names enough?
The AICPA's definition of confidential client information is not limited to records that still show a client's name. ET 1.700.060 can apply even when the client is not specifically identified. If the information remains confidential client information, specific consent, preferably in writing, is still the usual requirement.
Read the Code at ET 1.700.001, ET 1.700.060, and the ET 0.400 definition, and the longer discussion in AICPA confidentiality and data licensing.
Is a license of firm-owned records the same thing?
No. A possible license of a copy of firm-owned operational records is a different question from selling a pile of anonymized client files. The accurate verb is still a license of a copy, not a sale of the firm. Client and tax-return material should stay out unless required consents are actually in place.
Start with What is data licensing? and Can a CPA firm license its data? For tax-return rules, see IRC 7216 and data licensing.
What should a firm tell a buyer who asks for anonymized files?
Pause and get advice. Ask your own counsel or ethics advisor to review the proposal, the inventory, and any consent language before you say yes. A cautious no is often the right first answer. I won't tell you a particular deal is permitted, and Balance Sheet Data is not a buyer.
