This is worth reading in full. Here's my breakdown of what actually matters for your practice. AI is already in your firm. The bulletin says it outright — document review platforms, research tools like Westlaw and Bloomberg Tax, it's already there. The only question is whether you're using it intentionally or not. You own everything that goes out under your name. §10.22 due diligence doesn't disappear because a machine drafted something. The bulletin cites a Deloitte Australia case where AI invented judge quotes and referenced reports that don't exist. Deloitte had to refund part of their fee. Review everything before it goes to a client or the IRS. The IRS called out hourly billing directly. Under §10.27, if AI cut your time on a matter and you billed as if it didn't, that's a problem. The bulletin is explicit: cost savings should be passed on or reflected honestly. If your pricing model is purely hours-based, this guidance gives you a concrete reason to make the shift to value pricing. Data protection is now a compliance issue, not just good practice. Civil and criminal penalties under §7216 apply if client data ends up in an unsecured system. Only use AI on enterprise plans that don't train on your inputs. This is non-negotiable. Get a written AI usage policy on file. §10.36 requires it, and the bulletin lays out exactly what to cover: staff training, data handling protocols, and vetting of any third-party tools. It's not a heavy lift, and not having one is the bigger risk. Read it here: IRS OPR Bulletin, June 24, 2026
