Tax Research That Takes Minutes, Not Half a Day

Ask any corporate tax professional what eats their week and you'll hear some version of the same answer: research. Chasing down the right ruling, reconciling a Treasury reg against a recent Tax Court decision, then turning all of it into a defensible memo that a partner or a CFO will actually sign off on. It's careful work, and it's slow. That's the part AI is genuinely changing.

We've been putting generative AI to work on the first draft of that process — the pulling-together, not the concluding. You feed it the fact pattern and the question, and it comes back with a structured research memo: issue, applicable authority, analysis, a tentative position. The good tools now cite to the actual sources — the specific IRC section, the reg subsection, the PLR or revenue ruling — instead of gesturing vaguely at "the code." That citation trail is the whole game. A memo you can't trace back to authority is a memo you can't use.

Where the hours actually disappear

The time savings aren't evenly spread, and it's worth being precise about where they land. Straightforward questions — the characterization of a payment, whether an expense is currently deductible, the mechanics of a fairly common election — used to take a junior associate a few hours to research and write up. Now it's a fifteen-minute draft plus a review. The harder, more novel questions still take real thinking. But even there, the AI clears the underbrush: it surfaces the authorities you'd have spent an hour finding, so your billable brainpower goes to the judgment call, which is where it belonged all along.

I've seen teams try to measure this and land somewhere around a 60-to-70% reduction in drafting time on routine research. That's real. It's also not the number to lead with when you talk to your risk committee.

The part you can't automate away

Here's the honest caveat, and we say this to every client before we say anything else. These models still fabricate. A citation that looks perfect — right format, plausible section number, confident tone — can point to a ruling that doesn't exist or say the opposite of what's claimed. So every cited authority gets pulled and read by a human. Not skimmed. Read. We treat the AI output as a very fast, occasionally overconfident first-year associate: useful, fast, and never the final word.

The workflow that holds up is a tiered one. AI drafts. A qualified preparer verifies every citation and the reasoning. A reviewer with signing authority owns the conclusion. Nobody's title changes; what changes is that the preparer starts from a 70%-complete draft instead of a blank page.

Is this going to replace tax professionals? No — and anyone selling you that is selling you a lawsuit. What it does is take the least valuable hours of a smart person's week and hand them back. For a department drowning in research requests, that's plenty.
