Additional costs after building the house

For us, with four people on ~160m2, it looks as follows:

Residential building including photovoltaic system and elemental coverage: €44.33
Household contents: €8.31
Telekom VDSL250: €49.95
Residual waste and organic waste: €21.36
Electricity including heat pump €120 (might possibly be adjusted slightly downwards)
Property tax: still unknown, likely around €50 per month
Water, sewage, canal: €80

yes meant you.

Oh, my father in Bremen has a condominium in a 4-family house with about 120 m² and pays 800 EUR property tax per year. That’s on the subject of the East-West difference.

Property tax does not indicate whether you built expensively. They want to know if you have art, etc.

Well, in the standard valuation, which forms the basis for taxation, definitely no one asks about art.
Equipment regarding the building yes, private items definitely no.

The question is clearly what you want to achieve with it – that it is fair to tax wealth here is just my opinion. But as I said, that is a matter of opinion.

By the way, I also find it bold to consider it settled with the real estate transfer tax, especially in areas where farmers practically support their entire family with huge plots of land that may be built on and for which no real estate transfer tax is ever paid.

Oh yes! The equipment, floor coverings, etc. are being inquired about. This starts at around 200m2. Sometimes they even come by. Unimaginable but true.

A floor covering is not an art object but a fixture. By the way, according to case law, the limit is 220 sqm of living space; below that, you don't even have to list them, only your living space. I can recite the explanations to you; you will practically find no question about your "personal belongings."
