Why connected data matters for tax technology modernization

Most tax leaders don’t need convincing that their department should modernize. What’s harder to picture is what modernization actually looks like on an ordinary Tuesday — not in a vendor deck, but in the hour-by-hour reality of preparing a return, closing a provision, or answering an auditor’s question.

That gap between wanting to modernize and knowing what “modern” looks like in practice is showing up clearly in the data. According to the 2026 Corporate Tax Department Technology Report, satisfaction with tax technology fell to 34%, from 56% a year earlier. Nearly two-thirds of tax departments (64%) remain stuck in the chaotic or reactive stages of technological maturity, a number that has risen, not fallen. Tax teams aren’t short on ambition. They’re short on a concrete picture of the destination.

That destination isn’t a bigger tech stack. It’s connected tax data, in place of the disconnected handoffs most direct tax teams navigate today. The report calls this the frustration gap — and by its own numbers, it’s widening.

What does tax technology modernization actually look like?

The 2026 Corporate Tax Department Technology Report maps this journey as a Technology Maturity Curve, running from Chaotic (9% of respondents) and Reactive (55%) through Proactive (29%), Optimized (5%), and Predictive (2%). In plain terms: at one end, teams run compliance out of email and spreadsheets with little connection to enterprise data. At the other end, tax workflows are automated across the business, and the department spends its time advising on risk and strategy rather than assembling numbers.

The encouraging news is that this shift is already underway at scale — 67% of respondents say technology investment has helped move their department toward more strategic, proactive work. Modernization isn’t a hypothetical for some future budget cycle; it’s already changing how most tax departments spend their time. The real question for any team still stuck lower on the curve is what, specifically, is holding them back.

Where does direct tax data break down between systems?

For most teams, the answer lives in the handoffs — what one analysis calls data’s tortured journey through the tax lifecycle. Direct tax data typically moves through five stages — ERP, tax provision, income tax return, statutory reporting, and audit response — and, as a recent infographic on the connected tax data journey lays out, each handoff between those stages is a place where numbers can drift.

Data pulled from the ERP gets exported and re-keyed by hand into the provision system, and every manual touch is a chance for a number to shift. The provision and the return should tell the same story, but when the two systems don’t talk to each other, the tax team ends up reconciling two versions of the truth. Local statutory filings don’t wait for spreadsheets to catch up, so under-resourced teams spend hours closing gaps that shouldn’t exist in the first place. And when an auditor eventually asks how a number was calculated, a fragmented process means digging back through months of disconnected files rather than pointing to a clear trail.

The cost of this shows up in the numbers: 58% of tax departments describe themselves as under-resourced, and 44% incurred a tax penalty in the past year — 12% of those penalties topped $1 million. None of this is abstract. It’s the texture of a tax team’s actual week.

What changes after modernization: A direct tax team’s workday, before and after

The clearest way to see what changes when data is connected is to look at where the hours actually go. A commissioned November 2025 Forrester Consulting Total Economic Impact™ study of organizations using Thomson Reuters Direct Tax found the following:

	Before: spreadsheet-dependent	After: connected
Data collection	Exporting and re-keying data from the ERP by hand	Data flows in automatically, already mapped to the right fields
Reconciliation	Reconciling provision against the return by hand — hours per return	Numbers match by design; one source of truth for both
Time per return	About 40 hours on average	About 20 hours — a 50% reduction
Where the hours go	Data entry, chasing versions, prepping documentation for audit	Analysis, forecasting, and advisory conversations with the business
Headcount pressure	New jurisdictions or growth often meant new hires	Composite organization avoided hiring two additional resources per year while scaling

 

A closer look at what a provision-close night actually involves shows senior tax professionals spending it moving data, not doing tax work. The hours weren’t eliminated — they were relocated. The time that used to go into collecting and reconciling data now goes into analysis and planning. That’s the practical, day-to-day meaning of “insight-driven”: not a new job title, but a different split of the same working hours.

How to build the ROI case for the conversation with finance leadership

For a VP Tax or Tax Director building the case for a direct tax technology modernization strategy internally, the harder audience isn’t the tax team — it’s the CFO. The same Forrester study gives that conversation a concrete foundation: a composite organization modeled on real customer interviews saw a 148% return on investment over three years, a net present value of $1.7 million, and payback in under six months.

That return breaks down into three categories finance leadership will recognize immediately.

• Avoided compliance costs — fewer penalties, less rework, lower consulting spend — contributed roughly $667,000 in three-year present value.
• Reduced tax preparation time, the 50% reduction shown above, contributed roughly $1.2 million.
• Avoided hiring — the composite organization scaled into new jurisdictions without adding headcount — contributed roughly $915,000.

One interviewee, a senior director of finance and business operations in the software industry, put the shift plainly: “We have gone from reactive compliance to regulatory confidence and proactive insights.”

That’s the version of this story a Tax Director can actually bring into a budget conversation: not a request for more resources, but a case for reallocating the resources already in the room. Building that case well starts with knowing which numbers will actually move a CFO.

One login, one interface, one source of truth

This is what Connected Compliance is built to solve — because, as the numbers on disconnected tax systems show, the constraint was rarely about headcount. It was about how little the underlying systems talked to each other. Instead of data traveling through five disconnected systems and re-keyed by hand at every handoff, direct tax data flows from the ERP through provision, the return, and statutory reporting inside one connected platform — one login, one interface, and one source of truth from source data to final filing.

It doesn’t ask a tax team to rebuild its process from scratch. It closes the specific gaps described above — the re-keying, the dueling versions of the truth, the reconciliation scramble, the missing audit trail — so the hours a team already has can go toward the strategic work most tax leaders are being asked to deliver.

From spreadsheets to strategy: Where to go to start a modernization plan

Moving from spreadsheets to strategy isn’t a five-year transformation project, and it doesn’t require a bigger team. It’s a shift in where the hours already on the calendar get spent — and the data above shows what that shift is worth in dollars, hours, and risk avoided.
