Enter here the start date of the energy measure.

The following applies to the start date of the energy-efficiency measure:

• for measures for which a building permit is required, the date on which the application for a building permit was submitted is considered,
• for measures that do not require a building permit and for which construction documents must be submitted, the date on which the construction documents were submitted is considered,
• for other measures that do not require a permit or notification, the actual start date of construction work on site is considered.

The expenses for issuing a technical certificate can also be claimed for tax purposes.

The statement of the energy measure can be confirmed by a specialist company or an energy consultant (a person authorised to issue statements in accordance with § 21 of the Energy Saving Ordinance).

The installation or replacement of roller shutters and external shading elements is considered summer thermal insulation.

The eligible expenses can generally be taken from the certificate of the specialist company.

The tax reduction cannot be claimed if the expenses have already been taken into account as business expenses, income-related expenses (e.g. in the case of double household management), special expenses or exceptional costs.

Enter the name of the specialist company that carried out the energy measure.

The specialist company or an energy consultant issues the certificate, which you must submit to your tax office.

Specialist firms that are working in the field of building renovation are entitled to issue the technical certificate. In addition, the certificate can also be issued by an energy advisor (a person authorised to issue energy performance certificates in accordance with sect. 21 of the Energy Saving Ordinance).

The certificate is always issued to the owner(s) of the residential building or flat.

Flat owners' associations: If energy measures are carried out on a building consisting of several owner-occupied flats, a separate certificate must be issued for each individual flat.

Enter here the end of the energy measure.

The tax reduction can only be claimed when the energy-saving measure has been completed and you have a corresponding technical certificate from a specialist company or energy consultant.

If the energy efficiency measure is only completed in the year 2023, the expenses can be claimed for tax purposes only in the next year.
