Rent income is income.

> It's your property, what business is it of the government's?

You could argue that renting an apartment puts a burden on the community - the people that rent it need to drive there, they use public roads and public resources. However, that argument is false. The argument behind taxes is that there is a government that allocates certain resources towards community goals - security, infrastructure, welfare. These resources need to be paid for and so the government raises taxes - on income, on property, on cars etc. All the money collected gets redistributed and none of it is tied to the sector it came from: My income tax pays for roads, railways, kindergardens alike even though I don't own a car and rarely drive and don't have any kids. And the legislative decided that renting a room is a taxable action and that's it - like it or not. It's really as simple as that.
