If the seller sells the real estate license after filing and paying taxes, but does not get the real estate license, it is very troublesome for the seller to lose these invoices, and it is necessary to go through the process of proof of loss, which is to publish the invoice number, amount, specific payer and other information of the invoices in the newspaper and explain them. Because it is impossible for the government department to re-invoice you.

If the house is a long time, at least 2 years, then the loss of the seller's original invoice has little effect on you. For the buyer, what you need to pay is the tax paid as a second-hand house transaction.
