What should tax couples do if they declare their mortgages repeatedly?
1. If both husband and wife declare special mortgage interest plus deduction, it can also be modified. One of them logs in to the personal income tax APP, then chooses his own house goods to add deduction, and the other chooses to cancel. If the husband and wife pay less tax because they choose the special deduction of mortgage interest, they can choose to pay by themselves or make up the deduction by the unit.
2. It should be clear that husband and wife can't deduct the mortgage tax at the same time, but they can agree to choose one of them, and the deduction method can't be changed within a tax year. If the husband and wife buy houses separately before marriage and have the first set of housing loans, they can choose one set to be deducted from the purchased houses according to the deduction standard of 100% after marriage, or both husband and wife can deduct the purchased houses according to the deduction standard of 50%.
