How to change paid interest and debt

When you have a joint loan with your spouse or cohabiting partner, the loan is entered only in one of your tax returns. You can easily split the interest expenses and debt between you in the tax return. Cohabiting partners/jointly responsible borrowers must distribute both the debt and the interest on the debt according to the respective percentages that you each own.

See how you make changes in item 3.3.1. Remember to make changes in both tax returns.
