Tax bonus for energy-efficient building measures: WSB info for homeowners

Do you live in a property that is more than 10 years old? If so, you can deduct the costs of energy-related building measures from your income tax as follows:

Year of completion of construction:
7 % of the costs, max. 14,000.00 euros

First subsequent year:
7 % of the costs, max. 14,000.00 euros

Second subsequent year:
6 % of the costs, max. 12,000.00 euros

The following are deductible
🍃 the cost of thermal insulation for walls, roofs and ceilings,
🍃 New windows and exterior doors,
🍃 the installation of a ventilation system and
🍃 the renewal of the heating system.

A number of conditions must be met for the tax office to play along:
✔️ You must live in the property yourself.
✔️ The costs may not be deductible as business expenses, income-related expenses, special expenses or extraordinary expenses.
✔️ The invoice must be issued in German.
✔️ Payment must be made in non-cash form.
✔️ There must be no other funding, e.g. KfW grant or monument depreciation.

In addition, the specialist company carrying out the work must issue a certificate for the construction measures in accordance with the officially prescribed model. The Federal Ministry of Finance recently outlined the details of this in an updated letter.
