Tax deductions for building renovations

Last updated: 15 July 2021

Since January 2020, Germany provides homeowners with tax incentives for energy efficient renovations, allowing them to deduct 20% of the costs for renovations of up to EUR 40,000 from their taxes.

Insulation measures, new windows and exterior doors, the replacement or optimisation of old heating and ventilation systems and the installation of digital energy management systems are eligible for support.


Measures cover only owner-occupied homes. This rules out rented dwellings and means that less than half of Germany's approximately 42 million homes are eligible for support. A study by the German alliance for energy efficiency in buildings, GEEA, projects that the approved measures could save up to 3.4 million tonnes of CO2 equivalents by 2030.
