About a month after we signed at the notary, the letter from the tax office arrived ;)
That was probably the real estate transfer tax, not the property tax?
For us, the first property tax assessment came after about 2 years – for the empty plot. Since then, we have been paying it.
To this day, we don’t even have the standard value, which the tax office is supposed to determine (or not :)).
I believe they can demand back payments for 5 years ... I put aside €100 per month for that.
