Correcting wrong data at the RCS
Published on 10 October 2026 · Updated on 10 October 2026
In short
To correct RCS data in Luxembourg, you make a rectifying filing when an earlier filing contains a clerical error, and an amending filing when the situation has changed without being declared. Filings are made online through the LBR, within one month of the event, and are published in the RESA.
Rectifying filing or amending filing
| Rectifying filing | Amending filing | |
|---|---|---|
| When | An earlier filing contains a clerical error | The filed information has since changed |
| Example | A manager’s date of birth entered wrongly | Manager replaced, never declared |
| Key document | Reference of the filing to correct | Decision or deed recording the change |
| Fees | Same fee as the initial filing | Filing fee, increased if late |

A filing is never erased
A deed or document filed with the RCS is neither destroyed nor returned. The wrong filing remains available for consultation: the rectification is added to it and states clearly what it corrects. An error in a notarial deed is corrected with the notary who received it.
Fees for a change declared late
A change declared out of time attracts increased fees under the LBR scale: €50 excl. VAT during the 2nd month after the event, €200 excl. VAT from the 3rd to the 4th month and €500 excl. VAT from the 5th month, on top of the filing fees. Rectifying and amending filings follow the same fees as initial filings.
The most common errors concern the address of the registered office, the identity or powers of the managers, the list of SARL shareholders and expired mandates. For a change that was never declared, see also filing an amendment with the RCS. For beneficial owners, the procedure falls under the RBE: see RBE compliance.

Frequently asked questions
How do you correct an error on the RCS extract?
If the error comes from an earlier filing, you make a rectifying filing through the LBR, stating the references of the filing to be corrected. If the data was correct at the outset but has changed since, you make an amending filing with the document that records the change.
How much does a rectifying filing cost?
It is subject to the same payment as the initial filing, under the LBR scale set by grand-ducal regulation. Increased fees are added when a change is declared after the one-month period. Payment is in principle made electronically at the time of filing.
Who can file a correction with the RCS?
The company itself, an agent such as Business Registration, the notary who received the deed, the Chamber of Commerce or the Chamber of Crafts. Filings are made electronically, with assistance available by appointment at the LBR counter. An electronic certificate is required.
When is the correction visible?
It is published in the RESA on the day of filing or on a date chosen within the following 15 days. It is enforceable against third parties only from that publication. The RCS extract reflects the new data as soon as the filing is accepted, and the earlier filing remains visible in the file history.
