A real estate GmbH typically pays 30% total tax on rental income: 15% corporate tax plus 15% trade tax (regionally variable). With the extended trade tax reduction, this burden decreases to 15% — a halving. If the conditions are met.

What the regulation stipulates

§ 9 No. 1 Sentence 2 GewStG reduces the trade income by the part attributable to the administration and use of one's own real estate. The result: No trade tax is levied on the reducible portion. No trade tax is due. Effectively, only corporate tax (15%) plus solidarity surcharge remains.

For a real estate GmbH with €1 million annual surplus from rental income, this amounts to:

The conditions in detail

1. Exclusive administration and use of one's own real estate

The GmbH may only manage and use real estate. Even a small different activity can jeopardize the reduction — this is the most overlooked trap.

2. Permissible ancillary activities

Only narrowly defined ancillary activities are permitted:

3. Exclusion criteria

The following excludes the extended reduction:

Case study PV system

A real estate GmbH with 50 apartments installs an 80-kWp PV system on a roof. It sells electricity — and fails due to exclusivity. The entire extended reduction is lost for the entire rental result. A supposed optimization becomes a tax trap. Solution: outsource PV to a separate subsidiary GmbH.

Design options

Pure holding structure

Real estate holding GmbH holds several property GmbHs, each with exclusive management. This allows the reduction to remain possible at every level.

PropCo/OpCo split

Owner GmbH (PropCo) leases to operating GmbH (OpCo). PropCo benefits from the reduction, while OpCo assumes the operational risk. A classic structure for hotels, nursing homes, and logistics properties.

Shelf companies for new projects

Instead of overburdening the existing portfolio, new investments can be made through shelf companies. The reduction remains isolated for each subsidiary.

Minority threshold

The jurisprudence has developed a minority threshold: ancillary activities below 5% of revenue are harmless if they are functionally necessary (e.g., waste disposal in the rental agreement). However, this threshold is narrowly interpreted — in case of doubt, check with TABAK.

Documentation obligations

The reduction is applied for in the context of the trade tax return. Important: clear separation of income, no mixing of favored and non-favored activities. During the audit, the reduction is regularly a focus of examination.
