If the house is your wife's personal property before marriage, then she can only apply for tax refund herself. If the house is your common property after marriage, that is, the real estate license is named by two people, then both husband and wife can fill in the mortgage information to declare and enjoy the tax refund.

Tax refund means that after paying taxes, because some funds can be exempted from paying taxes, individuals pay more taxes, and these overpaid taxes will be returned to the tax account for tax deduction in the next tax payment cycle.
