Can the LIMOSA declaration be automated?

The declaration itself is always submitted on the official Belgian government portal, by you. But the work around it — building the worker file from their documents, preparing the declaration, storing the receipt and QR, and watching the expiry dates — is handled by Labourix. What used to be an evening of retyping becomes a minute of checking.

What is the LIMOSA QR code?

Every LIMOSA-1 receipt carries a QR code that opens the official verification page. Labourix stores the exact payload and shows the real, scannable QR on the worker's phone, so inspections are handled without paper.

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

Drop the document in. Hand Labourix the A1 or the ID and the worker's file builds itself — names, numbers, dates, all of it. You stop retyping.
The declaration comes back ready. Employee or self-employed, Labourix knows which one you need. You check it and you send it. That click is always yours, never ours.
The portal fills itself in. The Labourix browser extension works hand-in-glove with the official government website: open the declaration on the LIMOSA portal and every field — names, national numbers, dates, VAT — is filled in correctly, straight from the worker’s file. You review and press send.
The receipt files itself. The LIMOSA-1 lands back on the worker's record without you moving it.
The proof is in their pocket. At an inspection the worker shows a scannable LIMOSA QR that opens the official verification page. No paper, no panic, no phone call to the office.
The daily register is one tap. Check-in-at-work with nothing to type — ready for the stricter 2027 rules (check-in + check-out, real time, no pre-registration).

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.

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.

How does the autofill work on the government portal?

Through the Labourix browser extension. It works hand-in-glove with the official LIMOSA website: with the declaration open, it fills every field correctly from the worker’s file — the same data you already verified. Nothing is submitted automatically; you check the form and press send yourself.

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.
