Frequently Asked Questions (FAQ)

Is § 35c more worth it than § 35a?

In most cases yes, as § 35c also considers material costs and offers a much higher maximum amount (€40,000 instead of €1,200). However, the savings are spread over three years.

What counts as energetic renovation?

This includes, among other things, the insulation of walls, roof surfaces or floor ceilings, the renewal of windows or exterior doors, and the renewal or optimization of the heating system.

Do I need an energy consultant?

For the pure tax relief under § 35c, the certificate from the specialist company is often sufficient. However, an energy consultant can help plan the measures optimally, and the costs for this are also 50% tax-deductible.
