The verdict in three sentences
In tax season, a firm spends most of its load on repetitive data-entry and checking tasks that add no value for the client. An automation tool (pre-fill, consistency checks, electronic filing) costs EUR 15,000-40,000 and ships in 8-14 weeks. It saves 30-50% of data-entry time per return, an ROI read directly in freed-up hours.
Where automation saves time
| Task | Manual time / file | After automation | Saving |
|---|---|---|---|
| Trial-balance import and adjustments | 90 min | 30 min | 60 min |
| Consistency checks | 45 min | 10 min | 35 min |
| Schedule pre-fill | 60 min | 15 min | 45 min |
| Electronic filing | 25 min | 5 min | 20 min |
| Final review | 40 min | 25 min | 15 min |
| Total / file | 260 min | 85 min | 175 min |
That's nearly 2 h 55 saved per return, roughly 67% less data-entry time on the automatable tasks.
The hours-saved x number-of-returns maths
| Returns/year | Hours saved (2.9 h/file) | Value at EUR 55/h |
|---|---|---|
| 150 | 435 h | EUR 23,925 |
| 300 | 870 h | EUR 47,850 |
| 500 | 1,450 h | EUR 79,750 |
| 800 | 2,320 h | EUR 127,600 |
At 300 returns/year, a EUR 30,000 tool pays back in under eight months. Above 500 returns, the payback is measured in weeks.
Mini case study
Sophie runs a mid-sized accounting firm in Dublin producing 360 returns a year. Before automation, tax season pushes 6 staff into overtime. A EUR 28,000 tool with automated checks and integrated e-filing saves 2.9 h per file, or 1,044 hours/year valued at EUR 55: EUR 57,420/year. The investment is absorbed within the first tax campaign, and overtime falls 40%.

What does this automation cost?
EUR 15,000-40,000 depending on scope (checks, pre-fill, integrations). The timeline is 8-14 weeks.
Do automated checks replace human review?
No: they make entry reliable and flag inconsistencies, but expert review stays essential. The gain comes from fewer back-and-forths.
