For corrections
If a figure is wrong or out of date, the fastest fix is an email with a link to the official source — STATEC, the ACD, the CCSS, the Mémorial or the relevant Guichet.lu page. Bare assertions ("I think tax class 1a changed") are difficult to act on; a link to the new circular or the new bracket is immediately actionable. Corrections are credited in the page footer once reviewed, with a date and a short note describing what changed. The methodology page describes the corrections workflow in more detail.
For press and publishers
Same email. The site is open to being quoted and to talking to journalists working on Luxembourg coverage. If a piece is going to syndicate or republish material, please ask first; the licence is not implicit. World.lu is a small independent publication, not a company with a press desk, so please allow a few working days for a response.
What this site can't help with
World.lu is explanatory journalism, not professional advice. The editor is not a legal, tax, immigration, banking or medical advisor. Please don't email asking for personal advice on:
- Your specific tax situation, declaration or class.
- Your residence permit or visa file.
- Whether to buy or sell a particular property, or which mortgage to take.
- Which bank, insurer, school, doctor or notary to use.
- Investment, pension or wealth-management decisions.
Those questions need a licensed professional reading your actual file. The about page sets out the limits of what this site does and doesn't do. For the general explanation of a system — how tax classes work, what the CCSS does, how cross-border days are counted — start with the relevant guide and the resources it links to.
Response time
Within a few working days, usually. Not a same-day service. Some weeks the inbox is faster, some weeks it isn't. If a reply is genuinely urgent — for example, a factual error on a page that's being shared — say so in the subject line and it will be triaged accordingly.
What this site doesn't have
No phone number and no physical address. World.lu is a small independent site run by one editor, not an organisation with a reception desk. All correspondence is by email. There is also no contact form: a plain email gets a faster response and avoids the spam handling overhead of a public form.
