The verdict in three sentences
During tax season, a firm loses hundreds of hours to re-keying, manual checks and tool-hopping: an automation project (EUR 12,000 to 35,000) targets exactly this waste. Connecting to your production tool, automatic consistency checks and assisted return generation cut the time per file in half. The return on investment is measured over a single tax season, not over 5 years.
Hours saved per file: the real lever
The heart of ROI is the unit time per return. Automating repetitive tasks (data retrieval, checks, pre-filling) slashes that time without hurting quality.
| Return step | Average manual time | Automated time | Saving |
|---|---|---|---|
| Data retrieval/import | 45 min | 8 min | 37 min |
| Consistency checks | 35 min | 10 min | 25 min |
| Table pre-filling | 40 min | 12 min | 28 min |
| Review and adjustments | 30 min | 20 min | 10 min |
| Total per file | 150 min | 50 min | 100 min |
Per file, automation saves about 1 h 40. Across a portfolio of several hundred returns, the cumulative effect is considerable.
ROI over a tax season
Let's scale the saving to a full season, with a realistic loaded hourly cost for a firm staffer.
| Returns/year | Hours saved (1 h 40/file) | Value at EUR 42/h | ROI vs EUR 25,000 project |
|---|---|---|---|
| 150 | 250 h | EUR 10,500 | Paid back in ~2.4 seasons |
| 300 | 500 h | EUR 21,000 | Paid back in ~1.2 seasons |
| 500 | 833 h | EUR 34,986 | Paid back in the 1st season |
| 800 | 1,333 h | EUR 55,986 | Paid back in ~0.5 season |
Annual maintenance: budget 8 to 12 % of the build, i.e. EUR 1,000 to 4,200/year, to track regulatory changes (forms, rates, tax rules).

Mini case study
Marc, partner accountant at an 18-staff firm in Dublin. His firm processes 420 tax returns a year, heavily concentrated in the peak filing window. Today each return takes on average 2 h 30. An automation project at EUR 28,000, connected to his production tool, cuts that to about 50 minutes, saving 1 h 40 per file. Across 420 returns, that is 700 hours/year; at EUR 42/h, the saving reaches EUR 29,400 per season. The project is paid back in the first year, while cutting stress and overtime during peak season.
FAQ
Does automation replace the staffer's expertise? No, it removes low-value tasks (data entry, mechanical checks) so the staffer focuses on analysis and advice, where the real value lies.
Can it connect to any production tool? Most expose an API or export format. A 1 to 2-day upfront audit confirms feasibility and connection cost.
How long to deploy? Expect 6 to 12 weeks depending on the number of automated checks and the complexity of the production connection.
How are annual regulatory changes handled? Maintenance (8 to 12 %/year) includes updating forms, rates and rules. It is essential for a tax tool.
Must we automate everything at once? No. Start with the 2 or 3 most time-consuming checks, measure the gain, then extend. A first phase at EUR 12,000-15,000 proves value fast.
