I sold my object. Does this affect the tax bill?

Have you sold your object on a date other than 1 January? Then nothing changes. The situation as at 1 January determines the tax for the entire year. Usually, the notary public will charge the new owner for the portion after the transfer date. But this is not required or automatic. Have you bought an object on a date other than 1 January? Then you will not receive a tax bill for this object for that year.
