Bëllegen Akt: Tax Relief Now Linked to Energy Class Rating

A Strategic Reform for the Luxembourg Real Estate Market
The Luxembourg government is taking a new step in its housing and energy transition policy. The Minister of Finance has officially unveiled a major overhaul of registration duties, introducing an unprecedented modulation of the tax credit, better known as the "Bëllegen Akt." From now on, the amount of tax relief granted to buyers will be directly linked to the property's energy performance.
This measure aims for a dual objective: to boost real estate activity in key municipalities like Luxembourg City or Esch-sur-Alzette, while encouraging households to prioritize sustainable housing. According to initial announcements, the current ceiling could be substantially increased for properties with an A or B energy class.
How the New Bëllegen Akt Modulation Works
Until now, the tax credit on registration duties was a fixed amount per person (currently €40,000 following the temporary 2024 measures). The new bill proposes a progressive structure:
- Class A and B: An enhanced tax credit ceiling to encourage the purchase of new constructions or cutting-edge renovations in Kirchberg or Cloche d'Or.
- Class C to D: Maintenance of the standard tax credit for properties with intermediate performance.
- Energy Inefficient Buildings (Class E to G): A potentially reduced tax credit, unless the buyer commits to a certified energy renovation plan within two years of the notarized deed.
This reform responds to recent STATEC data showing an increasingly strong correlation between energy labels and the resale value of apartments in the capital and its surroundings.
A Lever for Decarbonizing the Housing Stock
Luxembourg's residential stock is responsible for a significant share of CO2 emissions. By modulating notary and registration fees, the state is sending a strong signal to developers and individuals. For a couple buying a house in Differdange or an apartment in Gasperich, the savings can represent tens of thousands of euros in additional equity at purchase.
Experts from the Chambre Immobilière welcome a measure that "restores purchasing power while preparing the future of housing." However, some professionals question the impact on low-income households wishing to acquire older properties for renovation in the North of the country or the Mining Basin.
Timeline and Implementation of the Measure
The implementation of this new scale is expected to be integrated into the state budget for application from the next fiscal year. Notaries in the Grand Duchy are already preparing to adapt calculations during the signing of sale deeds.
For investors and future owners, it becomes crucial to consult the Energy Performance Certificate (EPC) before any purchase offer. A property that is cheaper to buy but has a poor energy rating could now cost more in registration taxes than a modern, efficient property.
In conclusion, the modulation of the Bëllegen Akt by energy class marks the end of the uniform model and establishes sustainability as the new standard for the Luxembourg market.
