The parts of tax work that still need a person

Two forces are reshaping how California tax work gets delivered. AI is absorbing the routine preparation, and offshore teams are absorbing much of the rest. I've written about both separately. This is the part that matters more than either: what to do about them if you're the one building a career here.

This is our honest read, based on dozens of live searches this year and a lot of candid conversations with partners and tax professionals.

1. Signature authority is the asset

A CPA or EA can sign a return, represent a client before the IRS, and put a license behind a position. Neither AI nor an offshore preparer can do that, and this isn't a matter of opinion or firm preference.

The IRS Office of Professional Responsibility said so directly in June, in Alert 2026-19, its first formal guidance on AI in federal tax practice. Circular 230 Section 10.22 requires a practitioner to review AI-generated content properly before it reaches a client or the IRS, verifying facts, citations, and calculations. The OPR's framing is that technology is a tool, not a substitute for professional judgment.

Offshore delivery runs into a parallel constraint. Under IRC Section 7216 and Treasury Regulation 301.7216-3(b)(4), disclosing tax return information to a preparer located outside the United States generally requires specific, standalone taxpayer consent, with mandatory language when Social Security numbers are involved. The consent has to be knowing and voluntary, and it can't be a condition of service. Which means any individual client can decline to have their return touched offshore, and the firm has to absorb that.

Both of those rules point at the same place: a credentialed human, in the US, who takes responsibility. If you're early career, the single best move is to get in front of review responsibility and client contact as early as you can, even if that means a slightly slower run through the technical grind.

2. Advisory is where the money moved

Compliance work bills at compliance rates. The AICPA and CPA.com's CAS Benchmark Survey found median net client fees per professional reached $156,250, up 29% in two years, with CAS practices posting 17% median growth in a single year. Only about 10% of those practices still bill advisory by the hour. The profession has moved to recurring, outcome-priced work, and the firms doing it are pulling different economics out of the same headcount.

Cornerstone's 2026 billing data shows the same thing from the client side. The market has stratified into tiers, and the firms at the top aren't selling tax prep at a premium. They're selling risk management and decision support, which is a different product.

Automating routine work is how firms are trying to free the capacity to do more of it. In Intuit's 2026 survey of 725 accounting professionals, 86% expect AI to increase their ability to deliver advisory work over the next twelve months. That capacity has to be staffed by someone.

3. Specialize in something genuinely complex

SALT, international, real estate and 1031 structuring, trust and estate, M&A due diligence, construction. Anything with enough nuance and enough "it depends" that a standard offshore workflow and a language model both struggle with it.

I can't point you at a clean dataset for this one, so treat it as an observation from the searches I run rather than a statistic. But the pattern is consistent: generalist compliance work is where the pressure concentrates, and deep technical specialism is where it doesn't. Complexity is the thing that resists both automation and a documented offshore process, because both of those depend on the work being repeatable.

4. Learn to review AI output properly

The people pulling ahead aren't ignoring AI and they aren't being replaced by it. They're the ones who can review its output fast and correctly, know precisely where it's unreliable, and spend the recovered hours on higher-value work.

That skill is scarcer than the adoption numbers suggest. In Thomson Reuters' 2026 Future of Professionals Report, surveying 1,816 professionals across 62 countries, 74% already use AI tools several times a week, but 91% report some version of an AI value gap, meaning they can see what the technology should deliver and watch their organization fall short of it. Only around a fifth of organizations have a defined AI strategy at all.

The AICPA and CIMA's own research puts it more bluntly: 56% of respondents name generative AI as the most prominent skills gap in the profession. And in Intuit's survey, 77% agree the gap is widening between firms where AI is genuinely embedded and firms where it's occasional.

So most firms still aren't training for this properly. That's an opportunity if you get there first, and it's a fair question to ask in an interview.

5. Think hard about who you're working for

I'll be direct about this one, because it's the conversation I have every week.

PE-backed platforms and roll-ups will keep pushing AI and offshore delivery harder and faster. Inside Public Accounting's data backs that up: PE-backed firms make greater use of offshore staffing and show more operating discipline on realization and utilization. There's nothing wrong with that model if it's what you want. Scale, structure, defined tracks, often stronger compensation.

But the same data found PE-backed and independent firms posting identical organic growth of 7%, with independents currently delivering stronger partner compensation and distributing more of their earnings. So this isn't a choice between growth and stagnation, whatever the recruiting language on either side suggests.

If what you want is genuine partner-track equity, a firm where the person deciding your career actually knows your name, and technical work that stays in-house rather than getting routed offshore, that increasingly points toward an independent. And you need to ask direct questions about ownership structure and firm strategy before you sign anything, because not every firm volunteers it.

The trade

The volume of routine, hands-on-keyboard preparation work is going down. The value placed on judgment, relationships, technical depth, and the ability to run a piece of client work end to end is going up.

For anyone willing to move toward the second category, that's a good trade.

If you want to talk through where you sit, what your current seat is actually preparing you for, and what a smarter next move looks like, get in touch.
