... including wage shares, machine and travel costs
Enter the included wage shares, machine and travel costs.
You can find out the amount either in your service charge statement or the house charge statement (Nebenkosten- oder Hausgeldabrechnung) or from the separate "Statement according to sect. 35a of the Income Tax Act" (Bescheinigung nach § 35a EStG).
Important: As a rule, the "Statement according to sect. 35a of the Income Tax Act (EStG)" only shows the expenses for the work done by tradesmen according to sect. 35a. These then refer to the wage shares, machine and travel costs. In this case, you can enter the same value in both fields "Invoice amount" (Rechnungsbetrag) and "Included wage share" (darin enthaltener Lohnanteil)!
