From the 1970s to 2028

This Thursday, Luxembourg's Chamber of Deputies voted unanimously to modernise the country's tax administration. The legislation passed with zero opposition, which in a parliament known for its fractious debates is worth pausing on [1].

The reason for the consensus is simple: the current IT infrastructure dates back to the 1970s and 1980s. That is not a metaphor. The systems processing tax declarations in one of the world's wealthiest financial centres were built when disco was king and the Apple II was cutting edge.

The plan is ambitious. The government wants to push the proportion of electronic tax declarations from the current 17% to 85% by 2028. Paper filing will still be available for anyone who prefers it, which is a sensible concession. Not everyone wants to interact with a government portal, and some people genuinely prefer paper.

The price tag is EUR 226 million. The Finance Minister explained that this breaks down to EUR 193 million before VAT, with EUR 94 million going directly to the IT solution itself. The rest covers staff training and system adaptation. As he rightly pointed out, you cannot just install new software and call it done. The entire workflow has to change [2].

What caught my attention is the procurement appeal. A company that lost the initial court ruling has taken the public procurement process to appeal. A decision could come before summer, but the outcome is uncertain. This means a EUR 226 million modernisation project, unanimously approved by parliament, could be delayed by a single procurement dispute.

There is something nicely honest about the whole thing. The current systems are old. Everyone agrees they need replacing. The money is approved. And yet, the legal process still has to run its course. No shortcuts, no emergency exceptions. The system works slowly, but it works.

17% to 85% in two years is a steep curve. Luxembourg has pulled off ambitious digital projects before, but tax administration is politically sensitive. Every bug becomes a news story. Every delay becomes a criticism. The 1970s infrastructure held up for fifty years, but the replacement will be under scrutiny from day one.

I will be watching this one. Not because I file taxes (I do not), but because it is a rare case where the entire political spectrum agrees on a problem, a solution, and a budget. The only question is whether the implementation can match the ambition.
