AI Tax Prep in 2026: Not Quite There Yet

AI Tax Prep in 2026: Not Quite There Yet

Key Takeaways

  • AI tax prep is not really end-to-end yet. Most current tools handle data extraction, partial preparation or mapped inputs, but they do not prepare, diagnose, finalize and deliver a complete tax return inside established commercial tax software.
  • The tax software handoff remains the weak point. Whether a provider uses its own tax logic or simply pushes data, Lacerte or UltraTax still runs its own calculations, diagnostics and consistency checks. The CPA firm remains too involved for the final mile.
  • Proprietary tax platforms create a reset risk. When AI prepares most of a return inside its own software but cannot handle the final complex issue, the firm might be unable to transfer the incomplete return into Lacerte or UltraTax and could be forced to start over. Yuck.
  • K-1s and consolidated brokerage statements are not optional features. For firms preparing complex individual returns, these documents are central to the workflow. A platform that cannot process them is not ready for meaningful production use. Sorry, Thompson Reuters.
  • Cost matters when the beginning and end remain unchanged. Paying $100, $150 or potentially more per return is difficult to justify when source-document processing and final tax software review still require existing systems and experienced staff.
  • AI is useful today, just not where vendors keep insisting. Secure, PII-compliant environments can already support client narratives, engagement quoting, tax plan comparisons, strategy recommendations and internal training while end-to-end fully automated tax preparation remains elusive. For now.

At WCG, we will prepare approximately 4,500 1040s in 2026, many of them heavy on K-1s, rental properties, multi-state filings, and consolidated 1099 brokerage statements. We use SurePrep today, which scans documents and pushes data into UltraTax. It is not perfect, but it works. So when we started evaluating AI tax prep tools this year, the bar was straightforward: do more than SurePrep does, do it reliably, and do it in a tax software our team already knows (and has been tested by the CPA public).

After months of demos, pricing discussions, and candid back-and-forth with five of the major players, here is where things stand.

Attitude Adjustment Required

Some vendors in this space have developed a sales culture worth naming directly. Several conversations our team had this year carried an unmistakable undertone: that we should feel fortunate to be in the room. Demos were rationed. Follow-up questions were treated as obstacles. The posture was that these firms had something scarce and we needed to earn access to it.

That is a significant misread.

Nothing is broken at WCG right now. Nothing is broken in CPA tax prep land in general. SurePrep works. Our team is capable. We came to these conversations from a position of stability, evaluating tools that might improve on a workflow that already functions. The vendors who walked in acting like they were doing us a favor had not stopped to ask what we actually needed, or whether we needed them at all.

That question, what does a CPA firm actually need from AI tax preparation, seems to be one the industry has not asked seriously. The providers are caught up in their own momentum, and somewhere in that motion, the customer got left out. The result is a product landscape shaped by what these companies wanted to build, not by what firms like WCG need to operate. The vendors who will earn long-term relationships are the ones who come in with curiosity, not presumption.

The Disconnect Is Significant

When a CPA firm hears “AI tax prep,” we picture a system that ingests source documents, prepares a complete tax return, clears diagnostic errors, runs internal consistency checks, and produces a finished product in Lacerte or UltraTax (or your favorite top tier tax prep software) that a reviewer can open, approve and automate delivery.

When most AI tax prep vendors say “AI tax prep,” they mean something narrower. Some mean data extraction. Some mean a partial preparation inside their own proprietary platform. A few mean an API push of data into tax preparation software, which is largely what SurePrep and GruntWorx already do.

That gap is wide. And it explains why WCG is not committing to AI-assisted tax preparation this season. November 2026? Maybe. Today? Nope. No one is ready. No one.

Provider by Provider

WCG vigorously tested and demo’d the following providers. There might be more in this space, but these are the ones we chose to chase down.

TaxGPT

Not ready for production at a firm of our scale and complexity. They used pixel recognition within a browser which is basically AI navigating through a website like Proconnect and clicking and typing. It chewed up your laptop as well, so you couldn’t do other work. No integration to Office 365 unless you used the website version of email which no one on the planet does when we have Outlook. We will leave it there for now and revisit. They are the least prepared of these five.

Thomson Reuters Ready to Review

Works inside Thomson Reuters’ own environment, which creates problems we will get to shortly. Beyond the structural issue, it has a more immediate limitation: it does not handle K-1s or consolidated 1099 brokerage statements. On the roadmap for November 2026. Seriously? K-1s and 1099 consolidateds are on the roadmap? They are the roadmap for any serious tax return preparation.

For WCG, that is disqualifying. The bulk of our complexity lives in exactly those document types. Thomson Reuters does have a PII/SOC2 compliant research environment through their Co-Counsel product, which is useful for other purposes, but Ready to Review is not a fit for our practice.

Instead

Prepares tax returns in its own proprietary software. The concept is appealing until you think through what happens when a tax return hits a wall. No AI system today completes 100% of tax returns without some human involvement. Think Form 3115, an unusual depreciation method, or a client who surfaces a complex K-1 mid-engagement. When a tax return is 90% done inside a proprietary system and the last 10% requires a human decision, you are stuck. You cannot finish it there, and you cannot transfer a half-completed tax return into Lacerte or UltraTax or Proconnect or any other recognized software to pick up where AI left off. You start over. That is not a workflow inconvenience; that is a built-in reset cost every time AI hits its ceiling.

Oh, and you wasted money and time. Not just time.

There is also a longer-term problem. Client complexity tends to grow. A straightforward 1040 one year becomes a K-1-heavy filing the next. If your AI tool prepared prior-year tax returns in proprietary software, your history is trapped in that system. That creates problems for comparison, continuity, and review.

Black Ore

Occupies a third category that is worth understanding on its own terms. It is not proprietary software like Instead or Thomson Reuters Ready to Review, and it is not a straight data push like Juno. Black Ore ingests source documents, applies its own federal and state tax logic, runs internal calculations, builds workpapers, and performs anomaly detection before exporting mapped inputs into Lacerte. That is meaningfully more sophisticated than OCR and data entry.

The problem is where that sophistication lives. All of that work happens inside Black Ore’s own platform. Lacerte receives the resulting inputs, and then does what Lacerte always does: runs its own calculations, applies its own diagnostics, and performs its own consistency checks from scratch. Whatever Black Ore caught internally gets rechecked anyway. Whatever Black Ore missed shows up in Lacerte’s diagnostic queue, waiting for your team. The pre-prep intelligence layer does not shorten the back end of the workflow in any meaningful way, because the back end belongs to Lacerte regardless.

Your team still handles the actual Lacerte diagnostic cycle, e-file setup, 8879 generation, printing, and delivery. Black Ore replaces the first-level preparer, not the last mile. For a firm that already has SurePrep pushing data and experienced reviewers handling Lacerte, the question becomes: how much are we paying to automate the middle of a process whose beginning and end remain unchanged?

Black Ore’s pricing of $100 to $150 per tax return on average answers that question. At $100,000 to $150,000 annually, a firm is taking a significant financial position on a product in its early seasons. That is a lot of money to shorten the middle while the bookends stay the same.

Oh, and the $100 to $150 is their average… and it comes from $1 per scanned page and $3 per K-1 scanned page. We believe our cost would be more like $200 to $250 given the per page fee structure. So, you take SurePrep at $25 per tax return and add an hour of labor at $80 per hour (super high side) and you are staring at $105 compared to $200 to $250 plus the same $80 labor add-on. Not good.

Juno

Also integrates with Lacerte via API, and the architecture is sound for the same reasons as Black Ore. After working through demos and follow-up questions, though, it became clear that Juno is closer to a data entry tool than a full preparation system. Their own sales rep confirmed, candidly, that end-to-end tax return completion is not where they are headed. What they deliver is closer to SurePrep with a better interface. We already have SurePrep.

Sidebar: We giggled at the “end to end tax prep is not where we are heading.” Oh really? Your customers might have a different perspective on that. Adapt or die. We’ll see.

What WCG actually wanted from Juno was their PII/SOC2 compliant sandbox for uploading and analyzing existing tax returns. Juno declined to sell sandbox access on its own. So we are purchasing a block of 500 tax returns at $44 each, tax returns we have no plans to use, solely to get access to the compliance and secure environment with ZDR (which is fancy AI speak for zero data retention). If that arrangement sounds odd, it should. It is also a fair summary of where the AI tax prep industry sits right now.

Evolution Speed

We just highlighted a bunch of deficiencies in this space. Perhaps this is unfair. They are new. They are trying. We wish they understood their own limitations better, and applied that actual tax return preparation, but that will come. Tech-forward CPA firms like WCG will continue to provide pushback and feedback and resistance and everything else to help shape this space. We must in a very self-serving way. We must move off of compliance work and more towards advisory work. And to do this with fewer CPAs and tax professionals coming out of school. In other words, the pipeline is thinning yet the workload is not.

At the speed all this stuff is evolving, we suspect standards will emerge, and then we can have a gold standard be selected. Today? No standard let along a gold one.

What WCG Is Actually Doing

We are staying with SurePrep for tax preparation this season. We are not leaving that workflow until a solution genuinely improves on it in ways that justify the cost and the transition.

That said, we have identified a use for a PII/SOC2 compliant sandbox that is real and immediate. We will be using Juno’s sandbox environment to:

  • Upload tax returns to generate client-facing narratives
  • Upload tax returns for engagement quoting
  • Upload tax returns for tax plan comparisons
  • Upload tax returns for tax strategy recommendations
  • Upload tax returns for internal training purposes

That is not a workaround. It is a legitimate, high-value use of the technology at its current capability level.

What Comes Next

Before looking ahead, it helps to define what the gold standard actually looks like, because no one in this space has stated it plainly.

The workflow we are waiting for is straightforward in concept. Upload a client’s source documents, and the system prepares the tax return natively inside commercial tax software. Not Lacerte as a receiving bin for mapped inputs. Not a proprietary platform that hands off to Lacerte at the finish line. Not some unproven home-grown tax software that has zero community and how to resources. The AI works inside Lacerte, Axcess, UltraTax, or a comparable platform the way a human preparer would. It populates inputs, runs calculations, reads diagnostics, resolves them, handles e-file setup, and produces a finalized tax return that a reviewer can open, approve, and transmit. Start to finish, inside software the firm already owns and knows.

No one is doing that today. What exists is a spectrum of partial solutions, some more partial than others.

The space is moving fast, and that matters. The architecture, the coverage, and the pricing will all look different as these products mature. WCG is not closing the door on any of these providers. When a vendor can demonstrate that complete workflow on a K-1-heavy, multi-state 1040 inside Lacerte or something else, with a reviewer opening a finalized, diagnostic-clear tax return at the end, we will move quickly.

Sorry not sorry, but to trust a proprietary tax software that has been around for all of a minute is not a risk WCG wants to take on. Sure, a W-2 and 1098, neat. But complex tax returns? No thanks. We need battle-tested software like UltraTax, Lacerte, CCH Axcess  among others.

Sidebar: UltraTax is fundamentally flawed on its integration capabilities. Data can be pushed, sure, but for some sort of agentic AI tool manipulating UltraTax like a human is unlikely.

Until then, SurePrep and our team handle tax preparation, and we are putting AI to work where it genuinely delivers today.
