Corporate Income Tax

The taxable income is determined in the ZVE attachment, which leads directly to the tax assessment. It collects all tax-relevant data required for the tax assessment. If the tax bases are determined in other attachments, the result of this assessment will be included in the ZVE attachment.

The income from commercial operations is determined in the GK attachment. The income determined in the GK attachment is transferred to the ZVE attachment.

In the event of a tax group, the OT attachment must be completed by the tax group parent. The tax bases of the individual tax group members, determined for the tax group parent, are entered in this attachment. A separate OT attachment is required for each tax group member.

In the event of a tax group, the OG attachment must be completed by the tax group member. The tax bases relevant to the tax group parent are entered in this attachment.

The SPIF attachment must be completed if the tax payer has invested in a special investment fund (see also (Special) Investment Income). The corresponding amounts are transferred to the GK attachment, where they are included in the calculation of income from commercial operations.

The interest capping rule limits the interest expenses a company may deduct for tax purposes. The data required to determine the interest and EBITDA carried forward are entered in the Interest Capping Rule attachment. The deductible interest expenses, interest carried forward, and EBITDA carried forward are determined in accordance with section 8a of the Corporate Tax Act and section 4h of the Income Tax Act.

For tax groups, only the tax group parent, not the tax group member, must complete the Interest Capping Rule attachment. However, pre-tax group interest carried forward may need to be considered for the tax group member.

For companies with interest expenses below € 3 million, the attachment is normally not required unless an interest carried forward exists.

The deductible loss for the current assessment period determined in the Losses attachment is transferred to the ZVE attachment.

The uncompensated negative income for investment funds is determined in the Anlage Invest-Verluste (Investment Losses attachment). The form must be completed only by investment funds, not by their investors, as an attachment to the corporate income tax return and loss assessment.

This is where information relevant to the taxation of foreign intermediate companies pursuant to section 7 of the Foreign Tax Act must be entered (referred to as controlled foreign company taxation).

The data for the controlled foreign company taxation pursuant to sections 7, 8 of the Foreign Tax Act are entered in the ZwiG attachment. These data are transferred if a notice of assessment is already available (standard case).

A separate attachment must be completed for each sector to ensure appropriate loss offsetting.
