In 2024, I hired a company to maintain the garden of the house I use myself. Do these costs count as expenses for household-related services? How much are they taken into account?

The cost of garden maintenance is one of the costs that can be taken into account as a household-related service. You can receive a tax reduction of 20% of the expenses, up to a maximum of €4,000. The expenses can only be taken into account if you have received an invoice from the service provider and payment has been made non-cash, e.g. by bank transfer.
