The verdict in three sentences
During tax season, data entry and return checks tie up hours of low-value work. An automation project at EUR 15,000-45,000 integrated with your production software saves 30 to 50 % of data-entry time, with an ROI in 8 to 14 months. It is almost always more profitable than hiring to absorb the seasonal peak.
Automate or hire
Hiring adds a fixed annual cost for a mostly seasonal need. Automating turns a recurring labour cost into an amortised investment, with automatic checks that also cut error risk.
| Criterion | Hire | Automate |
|---|---|---|
| Year-1 cost | EUR 38,000 to 55,000 (loaded) | EUR 15,000 to 45,000 |
| Recurring cost | Salary every year | Maintenance EUR 200 to 500/month |
| Data-entry time saved | Linear (1 FTE) | 30 to 50 % structural |
| Error risk | Human | Reduced by checks |
| Peak scaling (tax rush) | Limited | Elastic |
| Cumulative effect | None | Growing each year |
Automated tasks and hours saved
Not all tasks are equal: some deliver immediate ROI. Here is a 2026 order of magnitude for a mid-sized firm producing several hundred returns.
| Automated task | Time before | Time after | Gain |
|---|---|---|---|
| Entry import and reconciliation | 3 h/file | 0.8 h/file | 73 % |
| Return consistency checks | 1.5 h/file | 0.3 h/file | 80 % |
| Pre-filling tax schedules | 2 h/file | 0.6 h/file | 70 % |
| Annex generation | 1 h/file | 0.2 h/file | 80 % |
| Chasing missing documents | 0.8 h/file | 0.1 h/file | 88 % |
Across 300 returns, an average gain of ~5 h/file is 1,500 hours, close to one full-time equivalent freed during tax season.

Mini case study
Sarah, partner at an 18-person firm in Berlin, produces 320 returns a year. Each return currently costs about 8 h at EUR 45/h loaded, i.e. EUR 360, EUR 115,200/yr total. An automation project at EUR 32,000, maintenance EUR 400/month (EUR 4,800/yr), cuts time by 40 %: EUR 46,080/yr saved. ROI: 32,000 / (46,080 - 4,800) ~ 9.3 months, then a net gain of ~EUR 41,000 each following year.
FAQ
What is the ROI of a tax-return automation project? As a 2026 order of magnitude, payback sits between 8 and 14 months by return volume and automation rate achieved, then the gain is net each year.
Do we need to change production software? No in most cases. Automation integrates via API or connectors with your existing software, without heavy migration.
How much is maintenance? Maintenance of EUR 200 to 500/month covers annual regulatory updates (new schedules, checks), fixes and supervised hosting.
Are the automatic checks reliable? They catch inconsistencies (balances, carry-forwards, thresholds) more consistently than manual review during the rush, reducing the risk of amendments.
Can we start on a limited scope? Yes. Starting with entry import and consistency checks, often 60 to 70 % of the gain, delivers fast first ROI before extending.
