Outsourced Company Secretarial Support in Luxembourg
Published on 10 October 2026 · Updated on 10 October 2026
In short
Company secretarial services cover the tasks that keep a Luxembourg company in order in legal terms: calling and documenting meetings and boards, keeping registers, filing every change with the RCS within one month and updating the UBO register. Outsourcing them ensures that decisions are valid and that filings meet the legal deadlines.
Definition
Company secretarial work is the set of company law formalities that follow incorporation: decisions of the company bodies, minutes, registers, filings and publications. It is distinct from bookkeeping, which produces the figures, and from legal advice, which is reserved to lawyers.
The deadlines that structure the year
- Annual meeting
- Within 6 months of the year end
- Filing of the accounts
- At most 7 months after the year end
- Change at the RCS
- Within one month of the decision
- UBO register update
- Within one month of the change
What our company secretarial service includes
- Calendar: tracking of the year end, the annual meeting, the end of the managers’ terms and the auditor’s term where applicable.
- Meetings and boards: notices, agendas, minutes and written resolutions where the articles allow them.
- Registers: register of partners or of registered shares and minute book, kept at the registered office.
- RCS filings: amendment forms, minutes, coordinated articles after an amendment of the articles.
- UBO register: checking and updating the beneficial owners after each change of ownership or control.
- Archiving: a centralised, up-to-date legal file for the bank, the licensed accountant and inspections.

Business Registration and company bodies
What we do not do
Business Registration does not keep the books, does not prepare the annual accounts and does not give legal advice on a dispute. Those tasks belong to an independent licensed accountant and a partner lawyer. Notarial deeds, such as an amendment of the articles of a SARL or an SA, are executed by a notary.
The most frequent decisions follow a known path: change of manager, registered office transfer or transfer of shares. Each leads to a filing of the change with the RCS and, often, an update of the UBO register.

Frequently asked questions
Does a small SARL need company secretarial services?
Its obligations are the same as those of a large company: annual meeting, filing of the accounts, registers, filings within one month. Many managers handle them themselves. Outsourcing is mainly justified when the partners are abroad or changes are frequent.
Do minutes have to be filed with the RCS?
Not all of them. Decisions that change information recorded at the RCS, such as the appointment of a manager or the transfer of the registered office, are filed and published. Others, for example the approval of the accounts, are kept at the registered office, while the approved accounts are filed.
Where are the company’s registers kept?
At the registered office. The register of partners of a SARL and the register of registered shares of an SA must be open to inspection by the partners. A domiciliation agent or a service provider can keep them for the company.
Does company secretarial work include filing the annual accounts?
We can file with the RCS once the accounts have been prepared by the licensed accountant and approved by the meeting. Preparing the accounts themselves remains outside our scope.
