Highlights
- Tax tech dissatisfaction jumped from 34% to 56% in a single year, even though most departments didn't change tools.
- Reactive, under-resourced departments report more penalties, lower forecasting confidence, and a bigger budget share going to external tax support.
- Departments don't need a full overhaul; fixing one manual bottleneck each compliance cycle moves them up the maturity curve.
A year ago, about a third of tax professionals told us they were unhappy with their department’s technology. Now more than half are. According to the Thomson Reuters Institute’s 2026 Corporate Tax Department Technology Report, dissatisfaction with the tax tech stack jumped from 34% to 56% in a single year — even though most departments didn’t change what they were using.
That’s the strange part. Tech adoption barely moved. Satisfaction cratered anyway. And this isn’t a story about any one platform underperforming — the data spans everything from spreadsheets to modern ERPs, and the frustration shows up almost everywhere. If you lead a tax department, you probably don’t need the survey data to recognize the feeling. What changed isn’t your stack. It’s the pace of everything around it.

Why tax technology dissatisfaction is rising
The Thomson Reuters Institute has a name for this: the frustration gap. It’s the widening space between what tax professionals know modern technology — especially AI — can do, and what their current systems actually deliver. You can see it in your own department, probably. You’ve read what’s possible. You’ve heard what other companies are doing. And you’re still exporting the same spreadsheet you exported last quarter.
The gap isn’t really about the tools tax teams have. It’s about awareness outrunning investment. As AI and automation get more visible everywhere else in the business, the comparison gets harder to ignore, and the tools tax has been living with start to feel more dated by the month, whether or not they’ve actually changed.
Half of this year’s survey respondents said their company hadn’t purchased any new tax technology in the past 12 months. Technology training has also declined, from 59% of departments providing it last year to 50% this year. Meanwhile, two-thirds of respondents still describe their department as merely exploratory or considering when it comes to AI adoption. Almost two-thirds (64%) still sit at the chaotic or reactive end of the Institute’s Technology Maturity Curve — a number that’s barely moved in three years.
Put plainly: the frustration is rising faster than the investment that would relieve it.
The cost of outdated tax technology
It’s tempting to read rising dissatisfaction as a mood problem. It isn’t — it’s the cost of outdated tax technology showing up in the numbers. The Institute’s research ties tax department technology maturity directly to measurable business outcomes, and the departments stuck lower on the curve are the ones absorbing that cost.
Start with penalties. Across the Institute’s research, tax departments that spend most of their time in reactive mode face a well-documented penalty risk: 56% report incurring penalties in the past year, compared to 31% of departments that spend most of their time working proactively. Under-resourced departments — which tend to be the same departments still stuck at the reactive end of the curve — also lean harder on outside help, spending a larger share of their budget on external tax support than well-resourced departments do.
Confidence takes a hit, too. Only 26% of under-resourced departments feel very confident they can forecast accurately for the business, compared to 43% of departments with adequate resources. The same gap shows up in penalty avoidance: 24% versus 37%.
Here’s what that gap in technology maturity costs, side by side:
| Cost dimension | Under-resourced / reactive | Adequately resourced / proactive | Gap |
|---|---|---|---|
| Penalty rate (past year) | 56% | 31% | +25 pts |
| Very confident in forecasting | 26% | 43% | −17 pts |
| Very confident avoiding penalties | 24% | 37% | −13 pts |
| Budget spent on external tax support | 44% | 37% | +7 pts |
| Technology maturity stage | 64% chaotic/reactive | 29% proactive | — |

And the gap compounds. Every compliance season that runs on manual data-gathering and spreadsheet handoffs is a season where review gets rushed, anomalies get less scrutiny before filing, and tax data gets buried in one-off workpapers that are hard to reuse next year. None of that shows up as a missed deadline. It shows up as longer hours, more rework, and less time for the forecasting and planning work tax professionals say they’d rather be doing. The Institute’s research shows tax professionals spend more than half their time on reactive work today, while they’d ideally spend roughly two-thirds of their time on strategic, proactive analysis.
What’s holding departments back from tax technology investment
None of this means tax leaders aren’t trying. Notably, the share of departments with someone formally in charge of leading tax technology strategy jumped from 51% to 88% this year — a real sign that leadership and accountability are taking hold. But leadership alone doesn’t close a resourcing gap. Budget and implementation resources remain constrained at more than a third of departments, and only about a quarter of tax leaders say they can secure the budget and resources they need when they need them.
That mismatch, more than any single statistic, is what’s driving dissatisfaction upward. But it’s worth naming what actually works: two-thirds of respondents say technology investment has already helped their department shift toward more strategic, proactive work. The investment closes the gap when it happens — it’s the timing that’s the problem. For departments still waiting on that investment, the gap between what’s possible and what they have keeps widening, and it’s getting harder to write off as just another compliance season.
How to modernize tax technology without a full overhaul
The good news is that moving up the Technology Maturity Curve doesn’t have to mean solving every constraint at once. Departments don’t need a complete technology overhaul to make progress — they need to find where manual work creates the most friction and address that first, one compliance cycle at a time. Connected, integrated tax platforms are built for exactly that kind of incremental progress: each piece of automation compounds, so the department that fixes one bottleneck this season is already ahead of the one that waits.
From fire drills to foresight: A proactive compliance season playbook walks through how tax departments can identify where they sit on the maturity curve today, and what a single, focused improvement — in data collection, workflow, or review — can do to move them up a level before the next filing deadline arrives.
Compliance season comes back around every year regardless of where your department sits on the curve. The question worth asking now, before the next cycle starts, is whether this season looks like the last one or whether something moves.
The frustration gap won’t close itself. But it also doesn’t require closing all at once.
