LIMOSA automation: the posted-worker declaration in one minute, not one evening

Knowledge base · LIMOSA & posting of workers · Updated July 2026

Every foreign worker or self-employed subcontractor working temporarily in Belgium needs a LIMOSA declaration before day one — and in construction, a missing declaration exposes both the foreign employer and the Belgian client to sanctions. Filing them by hand means retyping names, national numbers, addresses, dates and VAT numbers into the government portal. For every worker. Every project. Labourix takes that whole chain off your desk.

What changes for you

Why it matters: the expiry watchdog links it all together — when an A1 or LIMOSA nears its end date, you're warned weeks ahead, per worker, with traffic lights on your crew list.

From A1 scan to site check-in — automated

Set up your first worker in five minutes. Five days to decide.

FAQ

Is this allowed? Does it bypass the official process?

Nothing is bypassed. The declaration is submitted on the government portal, by you, under your own account. Labourix does the part a very good clerk would do — the one who never mistypes a national number and never forgets a renewal.

Does it handle self-employed subcontractors?

Yes. Employee or self-employed, you get the right declaration without having to work out which one applies.

What about renewals?

Labourix watches every LIMOSA and A1 end date and warns you before expiry, so renewals are filed before the old declaration runs out.
