Ask founders which part of setting up in Luxembourg surprised them, and the answer is rarely the permit or the filings. It is the bank account. Not because opening one is impossible, but because the timeline is driven by compliance reviews the founder never sees, and because arriving unprepared can add weeks.
What happens behind the counter decides your timeline, so let us look at it from the bank's side.
Why banks are slow, structurally
Luxembourg banks operate under strict anti-money-laundering rules, and a fresh company with a foreign founder is, from a compliance desk's perspective, a file full of open questions: who ultimately owns this, where does the money come from, what will the account be used for? Every question the file does not answer becomes an email, and every email is days.
The founders who open accounts quickly are not lucky; they are legible.
The file, from the bank's side
Expect to document, at minimum:
- Identity and background of founders and beneficial owners, matching what the RBE will say: who holds more than 25%, with IDs and often CVs.
- The company: draft or final statuts, RCS extract once registered, business permit or its application state.
- Source of funds. Where the share capital and early operating money come from, with paper (savings, salary history, a prior exit, a loan agreement).
- The business model. Expected activity, typical clients and suppliers, countries involved, projected volumes. Vague answers here are the single biggest generator of follow-up questions.
- Luxembourg substance. The registered office story, and why the account belongs here.
Sequencing around the account
For a notarial Sàrl, capital is deposited and blocked before incorporation, so the bank relationship starts early. For a Sàrl-S there is no blocked-capital certificate, which removes one dependency, but you still want the account open before serious invoicing starts. Practical order for most founders: permit application in motion, statuts drafted, then the bank file, then registration steps in parallel.
Traditional banks are not the only route. Payment institutions with IBANs open faster and work well operationally; many young companies run on one while a traditional relationship matures. The trade-offs are real (lending, cash handling, some counterparties' expectations), so treat it as a sequencing tool, not always the endgame.
How founders sabotage their own file
The same patterns produce the same delays:
- Inconsistencies. A different address, activity description or shareholder list in the bank file than in the permit or RCS papers.
- Undocumented capital. "Personal savings" with no trail behind them.
- Kitchen-sink activity descriptions. Listing every conceivable business line reads as evasive; describe what you will do in year one.
- Impatience with the process. Chasing daily does not accelerate compliance reviews; a complete file does.
What to realistically expect
With a coherent, documented file, account opening is a routine step. With an improvised one, it becomes the critical path of your whole incorporation. The work is almost entirely front-loaded preparation, which is also why it delegates well.
We prepare bank files alongside the incorporation itself, so the same facts appear identically everywhere and the compliance desk finds answers before asking. See how the full setup works, banking included.
