On 28 November 2024, the law transposing the Corporate Sustainability Reporting Directive (CSRD) was approved by the Chamber of Representatives. Although the transposition had been due for implementation since 6 July 2024, it marks an important step towards a more sustainable and environmentally friendly economy. The directive came into force on 5 January 2023 and aims to modernise and strengthen the rules regarding the social and environmental (ESG) information that companies must report.

The planned phases are as follows:
Although the CSRD’s reporting requirements will implemented in phases and will initially affect only large companies and organisations of public-interest, SMEs are also impacted.
Indeed, SMEs will be indirectly affected by the additional reporting requirements.
This is because companies at the top of the value chain, which do already fall within the scope of the CSRD, will often require social and environmental information from their suppliers and customers, regardless their size. In practice, this leads to significant administrative burden for SMEs.
The draft law recognises new challenges for SMEs under these obligations and also refers to the potential high costs that sustainable investments entail for Belgian companies.
To alleviate this burden, a protection mechanism was included. This mechanism stipulates that SMEs in the value chain should not be asked for more information than what is reasonably required by the European sustainability reporting standards for SMEs.
In practice, this means, on the one hand, that the information requested must be limited to what is provided for in the Voluntary Sustainability Reporting Standards for SMEs. On the other hand, there is a prohibition on requiring a certain level of assurance regarding information coming from SMEs in the value chain.
While the draft law is an important step forward towards greater transparency and sustainability in the corporate world, it also raises questions about its enforceability and the additional burden on companies, especially smaller players. The success of these measures will depend on the extent to which companies and regulators are able to balance reporting obligations with administrative feasibility.

•Real Estate, Renting and Co-ownership, Andersen in Belgium
Sustainable, green, energy-efficient or even climate-neutral: these terms have become commonplace in real estate communications. From the end of September, however, the use of such claims will be subject to stricter rules. The new rules aim to better protect consumers against misleading environmental claims.

•Tax Law, Andersen in Belgium
In its judgment of 18 June 2026, the Belgian Court of Cassation settled an important question concerning the deductibility of expenses incurred in making a holiday residence available to a company director: must these expenses be capped at the amount of the benefit in kind (BIK) taxed in the hands of the director? The Court answered in the negative.

•Tax Law, Andersen in Belgium
In a rather surprising judgment of 14 September 2026 (F.23.0097.F), the Belgian Court of Cassation failed to correctly identify the legislature's objectives when introducing the flat-rate tax regime for copyright and related rights income. The courts should swiftly distance themselves from this judgment!
