Belgian rules on forest groupings: the little-known tax instrument for investing in forests

Do you own forested land or are you looking to invest in forests while preparing your estate? Since 1999, there has been a legal structure specifically designed for this purpose: the forest grouping company. 

Yet, this instrument remains largely unknown. Below is an overview of its tax and estate planning advantages.

Why was the forest grouping created?

Private forest ownership in Belgium is among the most fragmented in Europe. Generations of inheritance have divided large forest areas into small plots that are difficult to manage individually.


To address this, the legislator adopted the law of 6 May 1999 (Act promoting the establishment of civil forest grouping companies), now incorporated into the Code of Companies and Associations (Art. 8:1 CCA).

A forest grouping is a company with legal personality whose exclusive purpose is forest production on the land it owns. It must be approved by the Minister of Finance in order to benefit from the favourable tax regime. There are now more than sixty such groupings in Belgium—a still modest but growing number.

The core of the system: tax transparency

The main advantage of an approved forest grouping is that it is not subject to corporate income tax (25%). Its income is taxed directly in the hands of each shareholder, in proportion to their participation, as if they personally owned the plots. This is known as tax transparency.

Since forest income for individuals is taxed on the basis of the cadastral income (a lump-sum value significantly lower than actual income), the tax savings can be substantial.

However, this regime is subject to conditions: four cumulative requirements must be continuously met:

  • Shares may only be held by natural persons (no companies).
  • The assets contributed must not previously have been used for professional activities.
  • The grouping must manage its assets as a “prudent and diligent person” (bonus pater familias), without speculation or active commercial activities.
  • No abnormal or gratuitous advantages may be granted or received (sale at undervalue, interest-free loan, etc.).
Failure to comply with any of these conditions will result in the grouping becoming subject to corporate income tax, sometimes as from the next accounting period.

Transfer of shares and gifts: remarkable tax advantages

The sale of shares is highly attractive from a tax perspective: it is treated as the sale of movable property, without registration duties (often 12.5%) that apply to traditional real estate transactions. Any capital gain realized is tax-exempt if it falls within the normal management of private assets. Only speculative transactions are taxed, in principle at 33%.

In the case of transfers free of charge, the advantages are even greater. In the Walloon Region (often the most relevant region for forests), the donation of shares in a forest grouping relating to assets located in forest areas benefits from a 0% registration duty (Art. 131quater Registration Duties Code), and inheritance tax is also exempt under the same conditions (Art. 55 Inheritance Tax Code). However, these provisions apply only to donors residing in Wallonia.

Finally, the initial contribution of land to the grouping is subject to a 0% registration duty, provided that the contributor is a natural person and the assets are not intended for residential use.

An interesting tool for estate planning

By bringing parcels together within a corporate structure, the fragmentation caused by inheritance is eliminated. Shares, which are easily divisible and transferable, lend themselves to gradual and structured transfer over several generations.

Combined with the various exemptions and the absence of taxation on transfers within normal asset management, the forest grouping becomes a genuine tool for intergenerational transfer at very low tax cost.

The corporate structure also makes it possible to organize the governance of the assets (voting rights, management powers, income distribution) independently from economic ownership.
