Legal obligations for Luxembourg companies
Key requirements, explained simply
Regular bookkeeping
Your bookkeeping must be kept continuously, complete and accurate (double-entry). Documents can be paper or digital, but must remain accessible in Luxembourg.
Law of 19 December 2002Document retention
Invoices, contracts, statements and supporting documents must be kept for 10 years (5 years in case of liquidation). A simple organization avoids time loss during closings, audits or bank requests.
10-year retentionAnnual accounts to prepare
Each year, you prepare your annual accounts (balance sheet, profit & loss, notes). The level of detail depends on company size and may trigger additional requirements.
Balance sheet, P&L, notesApproval on time
Accounts must be approved within 6 months after year-end, usually by the general meeting. This is required before filing.
6 months after year-endFiling with LBR and RESA
After approval, filing must be done within one month. In practice, this means no later than 7 months after year-end (e.g., 31/12 year-end → file by 31/07). Filing makes the information accessible and enforceable to third parties.
31 July deadlineLate filing fees
Filing after the deadline adds a surcharge, excluding VAT, of EUR 50 in the 8th month, EUR 200 from the 9th through the 11th month and EUR 500 from the 12th month.
