The verdict in three sentences
A tax filing automation project (document OCR, consistency checks, electronic filing, automated reminders) is priced between 12,000 and 30,000 EUR in 2026, over a 3 to 5 month timeline. The main gain is measurable: 15 to 25 hours per tax period per staff member, with a clear reduction in errors. This kind of project often pays back within the first tax season.

Where the real gain hides
Time lost in a firm is not in tax judgment but in collection and re-entry. A staff member spends a large share of the tax period chasing clients, re-keying documents and fixing inconsistencies caught late. By shifting these tasks to OCR, automated checks and a collection portal, the staff member refocuses on review and advice, where value is higher.

Sophie, partner at a 15-person firm in Lille, prepares about 220 returns per season. She estimates the gain at 20 hours per staff member per tax period through automation. For 15 staff, that is 300 hours per season, or 600 hours across the two annual periods. Valued at 40 EUR loaded hourly cost, the gain reaches 24,000 EUR per year. With a 24,000 EUR project + 3,500 EUR/year maintenance, the investment pays back in a little over a year, before counting the reduced risk of errors and penalties.
FAQ
Does automation replace the staff member? No: it removes entry and follow-ups, but review, tax judgment and sign-off stay human. The staff member moves up the value chain.
Is OCR reliable on heterogeneous documents? 2026 engines reach good reliability, backed by consistency checks that flag any discrepancy before validation. No blind entry.
Should electronic filing be integrated from the start? Strongly recommended: one-click filing is one of the most visible gains and secures on-time submission.
How long before the next tax season? A reduced scope deploys in 3 months; aim to launch at least a month before the season to test calmly.
What concrete ROI? Expect 15 to 25 hours saved per staff member per period, often more than the annual project cost in the first year.
