Can an accounting or CPA firm license its data to AI buyers?

Updated · Sources linked below · By DataBrokering.com

Short answerOften yes, for firm-owned process material, but not for client tax information without consent. Under 26 U.S.C. § 7216, a tax preparer who knowingly or recklessly discloses return information commits a federal misdemeanor, and IRS rules require written, knowing and voluntary taxpayer consent. So most firms scope licenses to SOPs, reconciliation and review workflows, and checklists, not client files.

Why accounting firms are in demand

Business Insider reports that law and accounting “see especially high demand” from AI data buyers.5 micro1 lists “Finance & accounting: financial processes, SOPs, reconciliations, approvals, reporting workflows, and operational documentation” among the data it seeks.4

The hard line: tax return information

Section 7216 makes it a misdemeanor for anyone in the business of preparing returns to knowingly or recklessly disclose information furnished for a return, or use it for any other purpose.1 The Treasury rule says a preparer “may not disclose or use a taxpayer's tax return information prior to obtaining a written consent,” that consent “must be knowing and voluntary,” and that conditioning services on consent generally makes it involuntary.2

“A tax return preparer may not disclose or use a taxpayer's tax return information prior to obtaining a written consent from the taxpayer, as described in this section.”26 C.F.R. § 301.7216-3(a)(1)2

Client financial data can also fall under the GLBA, and Frankfurt Kurnit lists payroll and tax records and data from regulated systems among the material to exclude entirely, rather than rely on de-identification.3 Professional standards and state board rules on client confidentiality may also apply.

FAQ

Can a CPA firm sell client tax data to AI companies?

Not without meeting Section 7216. Disclosing tax return information without a written, knowing and voluntary taxpayer consent can be a federal misdemeanor, so most firms keep client tax information out of scope.

What accounting firm data do AI buyers want?

Process material that shows how accounting work gets done. micro1, for example, lists financial processes, SOPs, reconciliations, approvals, reporting workflows and operational documentation.

Does de-identifying client data solve the problem?

Not on its own. Frankfurt Kurnit recommends excluding payroll and tax records and regulated-system data entirely rather than relying on de-identification. Get advice on Section 7216 before licensing anything client-derived.

Is our firm too small?

Maybe not. micro1 asks for 30+ employees, but some buyers accept smaller accounting firms. The fit check routes you based on size, location and role.
