Do I need to pay taxes again if I lose the electronic invoice for buying a house?

The electronic invoice for buying a house was lost, and the billing unit lost the report. If you open another one, you don't have to pay taxes. Even if you open another one, you won't get a third of the tax.

The down payment invoice for house purchase belongs to the evidence of paying the down payment for house purchase, that is to say, it can prove the fact that the owner paid the down payment.
