Economic Substance in Luxembourg: Requirements for Holdings and Funds

Minimum substance requirements

• Physical premises in Luxembourg: dedicated office (not just a domiciliation mailbox)
• Qualified staff residing in Luxembourg, with skills matched to the company's activity
• Board meetings held in Luxembourg with sufficient frequency (at least quarterly recommended)
• Strategic decisions made in Luxembourg with documentation (minutes, exchanges, analyses)
• Luxembourg bank accounts with real transactions and local signatures
• Activity documentation: contracts signed in Luxembourg, correspondence, financial analyses

Substance level based on activity

The required substance level is proportional to the complexity and volume of operations. A passive holding owning a few participations can operate with 1-2 qualified employees and quarterly meetings. An intra-group financing company issuing significant loans must demonstrate a team capable of analysing credit risk, managing treasury and making lending decisions independently. A commercial operating company requires substance matched to its business volume.

Consequences of insufficient substance

Insufficient substance can lead to the denial of tax advantages by Luxembourg or foreign authorities: denial of treaty benefits, denial of the participation exemption, reclassification of flows as taxable income in the source country. Automatic information exchanges (CRS, DAC6) enable foreign authorities to identify substance-less structures and challenge tax arrangements.
