Your marital status affects your tax assessment and thus the tax calculation. This is done either according to the basic rate or the splitting rate.
Divorce in 2025
If your marriage was divorced in 2025, you can also specify since when you were permanently separated. This information is required to check whether a joint assessment with your (ex-)partner is still possible for the divorce year – for example, if you did not live apart for the entire year.
If you lived permanently separated throughout the tax year, a joint assessment is excluded. The tax will then be calculated according to the basic rate, and no further information about the spouse can be provided.
