Expenditures within the framework of a short-term employment relationship among family members.
I am currently renovating a residential building that will be rented out afterwards. My son (over 18), who is very skilled in craftsmanship, would like to help me during his semester break (4 weeks) and, for example, take over wallpapering work.
In order to possibly deduct these expenses for tax purposes, I would like to employ him for this period as a mini-jobber or in a short-term employment relationship through the Minijob-Zentrale.
Are these expenses tax deductible, or are tax authorities familiar with such a form of arrangement?
