To deduct your maintenance payments to an ex-spouse or permanently separated spouse as special expenses, their consent is required. This is because the recipient must declare the payments as "other income" for tax purposes.
The consent does not need to be obtained anew each year by the maintenance recipient and submitted to the tax office, as the application does. If the consent is already on file with the tax office and has not been revoked, make the required tick in Section B at the appropriate place.
As a maintenance recipient, you should make your consent to the Realsplitting dependent on the obligation of the maintenance payer to compensate for any tax and non-tax disadvantages you incur as a result of the taxation of maintenance payments.
