There are three personal income taxes to be paid by auctioning houses according to law, mainly because the person subjected to execution cannot provide legal, complete and accurate proof of the original value of the property. In the specific proportion, the tax provisions of the two acts of individual transfer of stock houses and auction of individual stock houses are different. Considering the particularity of the auction, if the person subjected to execution can't provide legal, complete and accurate proof of the original value of the property and can't correctly calculate the original value of the property and the tax payable, the individual income tax will be calculated and paid at 3% of the total transfer income.
