Real estate withholding tax: Fiscal bomb on Wallonia
The end of 2025 marks a major fiscal turning point for industrialists based in Wallonia. The Walloon Parliament voted to abolish the real estate withholding tax exemption that, since 2005, covered investments in industrial machinery and equipment.
What are we talking about in concrete terms?
As part of the Marshall Plan, Wallonia had chosen, as early as 2005, toExempt investments in machinery and tools from real estate tax, in order to support industrial modernization and competitiveness.
Under budgetary pressure, the Walloon government decided to end this exemption for investments made between 1 January 2006 and 31 December 2020.
As of the 2026 tax year, this equipment will again become fully taxable.
An immediate and structural financial impact
In the field, the effects are far from theoretical.
The first simulations carried out by ABV Development show that:
- the portion of the property tax linked to equipment and tools could at least double;
- for a company that has invested heavily in the modernization of its site, the additional annual burden can reach several hundred thousand euros, or even more;
- this increase is independent of any new investment;
A regime that is now limited in time
The new fiscal framework also introduces a change in philosophy:
- investments made between 2021 and 2025 still benefit from an exemption, but limited to five tax years;
- investments made from 2026 may also be exempt... but always for a maximum period of five years.
Unlimited exemption is therefore definitely a thing of the past.
Anticipate rather than suffer
In this new context, the question is no longer whether the impact will be real, but how real it will be for each site.
The taxable base of the withholding tax is based on technical elements (qualification of the goods, values retained, consistency with the investments that are actually taxable) that deserve a thorough analysis.
Chez ABV Development, we support industrial companies in:
- an accurate assessment of the financial impact of the reform;
- critical analysis of real estate withholding tax bases;
- the identification of legal optimization levers that are still possible in this new framework.
It is better to objectify the fiscal exposure of your site today than to discover the size of the bill on the next warning-role extract.
Property tax is not inevitable. Optimization levers exist to reduce the burden.
Thanks to our extensive experience and our established relationships with the competent authorities, we support you effectively at each stage of this optimization project.
