The IRS Office of Professional Responsibility recently issued guidance on generative AI use in federal tax practice (Alert 2026-19) — and it lands squarely on the kind of work we do every day in transfer pricing.
AI tools are increasingly part of the process — drafting a local file narrative, running a first-pass comparability search, or generating initial language on functional and risk analysis. That is real efficiency. But Circular 230 draws some clear lines around how that efficiency gets used:
Your name is still on the report. §10.22's due diligence standard means every AI-drafted section — functional analysis, industry overview, comparable set — gets independently checked before it supports a filed position. A fabricated fact pattern or a misapplied IQR calculation does not hold up under IRS scrutiny.
Fee transparency matters when AI speeds up drafting. §10.27(a) flags billing patterns where AI cuts the hours spent on a first draft or a database search, but the client invoice does not reflect it.
Know your tool, or don't use it. §10.35 requires understanding not just §482, §6662, and the related regulations, but how your AI platform generates narrative and selects comparables — including where its logic might quietly introduce error or bias into work meant to withstand IRS review.
Written advice needs verified inputs. §10.37 means AI-generated language on functional and risk characterization, comparable adjustments, or profit level indicators gets confirmed against source data before it lands in a report a client relies on.
Section 6662(e) has not gotten easier. Contemporaneous documentation still has to reflect genuine analysis and reasonable, verified assumptions — not an AI draft that has never been stress-tested against the facts, regardless of how polished the language reads.
At Valentra Tax Advisors, we treat AI the way this guidance describes: a real accelerant for documentation drafting and comparability research, paired with the same rigor we would apply to any transfer pricing position — because in this field, the defensibility of the analysis is the whole point.
