I own a holiday apartment on Mallorca. Can I claim the expenses for the caretaker service, which only takes care of mowing the lawn and watering the flowers during my absence, as expenses for a household-related service?

Yes, since the expenses were incurred in a household of the taxpayer in another EU country, the household-related employment relationships or service relationships there are also eligible. However, the maximum amounts for household-related services (20 % of the expenses, max. € 4,000) and for craftsmen's services (20 % of the expenses, max. € 1,200) can only be granted once in total. No independent maximum amounts apply to the household in the holiday home.
