Why are IFRS so widely used in Luxembourg?

In Luxembourg, the same company may have to present its accounts under two different frameworks:

• Lux GAAP, the national accounting framework;
• IFRS, the international standards widely used in internationally exposed sectors.

Understanding why IFRS hold such an important place in a country the size of Luxembourg, and knowing when they are required or optional, is essential for any company with investors, subsidiaries or partners abroad.

I. A financial centre geared towards international business

Luxembourg holds a singular position in Europe:

• the world’s second-largest domicile for investment funds, behind the United States;
• a leading centre for holding companies and international groups;
• a density of financial players out of all proportion to its size.

This reality has a direct consequence for accounting: capital, investors and counterparties are mostly foreign, and expect financial information that can be read across borders.

In this context, a purely national accounting framework quickly reaches its limits. IFRS answer this need: they provide a common language, understood by an investor in London, a bank in Frankfurt or a fund in New York. It is this pursuit of comparability and transparency that explains their growing use in the marketplace.

II. Lux GAAP or IFRS: who applies what

Contrary to a common belief, IFRS are not mandatory for all Luxembourg companies. Lux GAAP remains the default framework, and IFRS are only required in specific cases, inherited from the 2002 European regulation. The table below summarises the applicable requirements.

Since the modernisation of Luxembourg accounting law, most companies may opt for IFRS, both for their consolidated accounts and, under certain conditions, for their annual accounts.

Investment funds, securitisation companies and holding companies intended to raise international capital frequently exercise this option, even when they are not required to.

III. Why so many companies choose IFRS

Beyond any legal obligation, the voluntary adoption of IFRS answers concrete motivations:

• Access to financing: international banks and investors more easily read accounts prepared under a framework they know.
• Simplified consolidation: no need to restate the accounts of a Luxembourg subsidiary into the parent company’s framework.
• Enhanced credibility with partners, signalling a high level of transparency.

This choice is nonetheless not neutral. IFRS rest on a logic of fair value and economic substance, more demanding than Lux GAAP in terms of estimates, disclosures and monitoring. They require specific skills and a suitable information system.

IV. The key watch point: the link between accounting and tax

One Luxembourg feature deserves specific attention: the taxable result is closely tied to the accounting result.

Yet the statutory individual accounts, which serve as the basis for calculating tax and distributing dividends, remain in principle prepared under Lux GAAP. Moving to IFRS for these accounts may therefore change the taxable base and calls for rigorous prior analysis.

In practice, many groups keep statutory accounts under Lux GAAP and reserve IFRS for their consolidated statements or investor reporting.

Conclusion

While IFRS are mandatory for only a minority of Luxembourg companies, they have established themselves as the natural language of an internationally oriented financial centre. Adopting them is often an advantage in competitiveness and credibility, provided the technical and tax implications are properly measured.
