Lohnsteuer kompakt FAQs

 


Field help: Have you earned income from capital assets?
(Forms KAP, KAP-BET or KAP-INV)

Select "yes" if you had income from capital assets.

Note: Most investors do not need to provide details of their capital income in their tax return and can omit Form KAP.

However, details of your income from capital assets are required in Form KAP if, for example,

  • the capital income was not subject to tax deduction,
  • you wish to have the tax deduction reviewed in terms of its basis or amount,
  • you are liable to pay church tax and have received capital income from which capital gains tax but no church tax was deducted.

Form KAP-BET is to be completed for income and creditable taxes from investments that are determined separately and uniformly.

Note: Only investors who have capital income or creditable taxes from participation in a partnership need to complete Form KAP-BET.

Form KAP-INV is intended for declaring investment income that has not been subject to domestic tax deduction.

Note: Investors who hold investment shares that are held with a foreign bank or fund company must complete Form KAP-INV. Reason: The foreign financial institution does not pay withholding tax to the German tax authorities.

In this case, record all capital income received. Lohnsteuer kompakt will then automatically apply for a favourable tax treatment for all capital income.

Note: If you had shares that became worthless and were removed from your portfolio, the bank may not offset the losses. It may not include the losses in the loss pot. This applies even if you only have a single portfolio through which you conduct all share transactions. You must include the losses from worthless shares in your tax return. If necessary, ask your bank how it has treated losses from worthless shares.
