Short-term rental on Airbnb: am I required to report it to the tax authorities?
So, for about a year and a half I've been renting out my studio apartment in Milano through Airbnb when I'm not using it. I make around 800-1000 euros a month from it. A friend told me I need to declare it to the tax authority, but honestly I'm not really sure how it works and if I risk getting in trouble if I haven't done it so far. Does anyone know how to get things in order?
