Only a regulated professional in Luxembourg, such as a bank, a lawyer on list I or IV, a statutory auditor or a chartered accountant, can act as domiciliation agent. The agent and the company sign a written domiciliation agreement. Having no known address is a serious breach that can lead to court-ordered dissolution.

The name must differ from every existing company, and its availability is checked with the Luxembourg Business Registers before the deed. The company must also hold any authorisation its activity needs, such as a business permit, before it starts trading. Insurance, savings and investment businesses cannot use the S.à r.l. form at all.

The registry adds a surcharge to the filing fee: €50 between the 7th and 8th month after year end, €200 between the 8th and 11th month, and €500 from the 12th month. The surcharge is calculated automatically. We plan the accounts timetable with you so it never applies.

Because the S.à r.l.'s share capital must be fully paid in when the company is formed, so a bank has to receive it first. The bank then confirms the payment for the notary. Opening this capital account is often the step that takes longest, so we start the bank file as soon as your KYC is approved.

A full ownership chart up to the individuals at the top, ID and proof of address for each of them, and evidence of where the capital and their wealth come from. Expect questions about why the company is in Luxembourg, who takes decisions and what flows through the account. Group structures should include the documents of each parent company.
The shareholders approve them within 6 months of the financial year end, and the company files them with the RCS within one month of approval. That makes 7 months after year end the outer limit. Filing is online, and fees are charged per filing.

Within 15 days of starting a taxable activity, by filing an initial declaration with the Administration de l'enregistrement, des domaines et de la TVA (AED). The estimated turnover in that declaration sets how often you file VAT returns. The AED then issues the VAT identification number used on invoices.

The shareholders or the board decide, and the extract of that decision is filed with the RCS within one month. The change is then published in the RESA, the official electronic gazette. We prepare the resolution and the RCS filing.

The shareholders decide to dissolve the company before a notary and appoint a liquidator, who sells the assets and settles the debts. For a single-shareholder company, the sole shareholder's recorded decision does the same job. The company is closed and removed from the RCS only after liquidation ends.
