The rules

Six rules for every set of books.

They apply to sole traders, companies with legal personality, partnerships, economic interest groupings and Luxembourg branches of foreign companies.

Double entry

Every transaction is recorded twice, as a debit and a credit, in a system of books and accounts.

Sources: Guichet.lu, accounting obligations of businesses · Code de commerce, art. 9, 11, 13 and 16

Without delay

Entries are chronological, complete, faithful and recorded without delay, not left for the end of the year.

An inventory

Alongside the books, the business draws up an inventory of what it owns and owes.

The standard chart

Most businesses use the standard Luxembourg chart of accounts, the PCN, and validate their accounts on eCDF.

Kept in Luxembourg

Accounting documents can be on paper or electronic, but are stored in Luxembourg.

For 10 years

Books and documents are kept for 10 years, or 5 years in a liquidation.

Sources: Guichet.lu, accounting obligations of businesses · Code de commerce, art. 9, 11, 13 and 16

The standard chart of accounts

The PCN, in seven classes.

The plan comptable normalisé gives every business the same account numbers, so the authorities can read every set of accounts the same way. Its content is set by a grand-ducal regulation of 12 September 2019 and has applied in its current form since financial years starting in 2020.

Businesses that use it prepare and validate their annual accounts on eCDF before filing them with the RCS. See our guide to annual accounts.

Who doesn't use the PCN
  • Sole traders, SENC and SCS with turnover up to €100,000 excluding VAT
  • Special limited partnerships
  • Banks, insurers, pension funds, SICAVs and most CSSF-supervised entities
  • Companies that report under IFRS

In practice

Keeping your books, month after month.

What your accountant needs

  • Sales invoices you issue
  • Purchase invoices and receipts
  • Bank statements for every account
  • Payroll documents, if you have staff
  • Loan, lease and other contracts
  • Fixed asset purchases and disposals

Keep a duplicate of every invoice you issue: VAT-registered businesses must. On a VAT audit, the AED can also ask for your accounting data in its electronic FAIA format.

The lighter regime for small sole traders

A sole trader whose turnover excluding VAT did not exceed €100,000 in the last financial year can keep simplified accounts instead of full double entry.

Below the same threshold, sole traders, SENC and SCS are outside the PCN and do not file annual accounts with the RCS. They still keep their records for 10 years.

Choosing a legal form? Compare them in SARL, SARL-S or SA.
