Finding information
Data lives across ERPs, spreadsheets and entities — disconnected and inconsistent.
AI-native tax intelligence powered by deep tax expertise
The problem
The work arrives fragmented, so every cycle starts by rebuilding the picture before the real tax work can begin.
Data lives across ERPs, spreadsheets and entities — disconnected and inconsistent.
Teams spend weeks reconciling fragmented data before any real tax work can begin.
Cross-team handoffs, version control and approvals eat weeks out of every quarter.
Routine questions escalate to costly consultants because internal capacity is maxed out.
Tax becomes a bottleneck — forcing teams into a permanentlyreactive mode of operation.
The shift
Traditional tax operations
With A.Tax
The gain
You watch the position form, instead of receiving a result you have to take on trust.
The answer arrives in the meeting, not in the week after the meeting.
Drift and gaps surface before review — not after you have filed.
The build happens once and consistently, so the rework goes away.
Routine questions stop escalating into consultant hours — answered in-house.
Your most expensive people spend their time on judgment, not assembly.
The platform
One connected platform: your data and expert tax logic go in, AI runs consistent auditable workflows, and answers you can defend come out.

See it in action
A sample A.Tax session — plain-language questions, answers with the charts and tables already attached.
Hi A.Tax, can you show me my pre-tax book income by jurisdiction for the last 4 years — and the ETR of each jurisdiction per year?
Here's your pre-tax book income by jurisdiction for FY22–FY25, with total tax expense and ETR per year — straight from your connected ledgers.
| Jurisdiction | FY22 | FY23 | FY24 | FY25 |
|---|---|---|---|---|
| US | 285 | 308 | 333 | 352 |
| UK | 114 | 157 | 178 | 206 |
| Brazil | 70 | 105 | 119 | 137 |
| Japan | 101 | 85 | 111 | 163 |
| Total | 570 | 655 | 741 | 859 |
| Tax expense | 151.0 | 166.9 | 198.4 | 253.4 |
And here's how the effective tax rate moved across each jurisdiction.
| Jurisdiction | FY22 | FY23 | FY24 | FY25 |
|---|---|---|---|---|
| US | 24.1% | 24.7% | 25.6% | 26.7% |
| UK | 23.1% | 25.3% | 18.4% | 27.2% |
| Brazil | 34.5% | 22.6% | 36.3% | 36.1% |
| Japan | 31.5% | 32.2% | 33.5% | 32.9% |
| Consolidated | 26.5% | 25.5% | 26.8% | 29.5% |
Your ETR was stable historically, but it rose 2.7% in FY25 — most of that comes from the UK, where FY24 ran below the standard rates it had historically. Want me to explore the UK increase?

Thanks, exactly what I needed! Can you show how my ETR compares to my peers and industry benchmarks?
Of course — here are your historical ETRs against your peer median and the overall industry average.
| Year | Your ETR | Peer median | Industry avg |
|---|---|---|---|
| FY22 | 26.5% | 26.0% | 27.5% |
| FY23 | 25.5% | 26.2% | 27.6% |
| FY24 | 26.8% | 26.5% | 27.8% |
| FY25 | 29.5% | 27.0% | 28.0% |
