The tax authorities have broadened the assessment basis for real estate transfer tax. The background lies in the rules on the so-called "unified contract" (einheitliches Vertragswerk). As a result, when acquiring land that you subsequently have developed, not only the pure land value but also the construction costs including VAT may be subject to real estate transfer tax. The real estate transfer tax rate in North Rhine-Westphalia is currently 6.5% (it varies across Germany, ranging from 3.5% to 6.5% depending on the federal state).
According to the tax authorities, a so-called "unified contract", under which the entire property value is subject to real estate transfer tax, exists in the following cases:
-
The subject matter of the contract is the developed property, even if it is still undeveloped at the time the purchase agreement is concluded.
-
In the case of separate contracts: purchase of the land / construction services (= legal connection), if:
- the contracts are linked to each other
- the agreements are combined in a single deed
- an overall price has been agreed
- construction had already begun before the contract was concluded, or
- the property may, by agreement, only be sold to those who have previously granted a fiduciary power of attorney for concluding the remaining contracts
-
At the time the land purchase agreement is concluded, the purchaser can no longer freely decide whether or how the property is to be developed (= substantive connection).
-
The building contractor sells its properties only to interested parties who also conclude the contract for the subsequent construction with it (= de facto compulsion).
By contrast, no unified contract exists if the general contractor agreement for the construction originally offered is materially amended after the conclusion of the land purchase agreement. In that case, real estate transfer tax is calculated solely on the basis of the acquired land. Material deviations could include, for example:
- A change in the floor areas and/or construction costs by more than 10%.
- The construction of an additional building that is characteristic of the building project.
We therefore strongly recommend that, before finalising the purchase agreements, you consult your Rechtsanwalt (German Attorney-at-Law) or notary and also submit the draft contract to your Steuerberater (German Certified Tax Advisor) so that they can, if necessary, point out any real estate transfer tax consequences.
Frequently asked questions
Frequently asked questions
What does a unified contract structure mean for real estate transfer tax?
A unified contract structure (einheitliches Vertragswerk) exists when the purchase of land and the construction of a building are treated as a single economic transaction. In this case, real estate transfer tax applies not only to the land value but also to the construction costs, including VAT. This significantly increases the tax base.
When does the tax office assume a unified contract structure?
A unified contract structure exists, among other cases, when the land purchase and construction contracts are linked, a total price has been agreed, construction began before the contract was concluded, or the buyer can no longer freely decide on the type and scope of the building. A de facto obligation to build with a specific construction company also triggers this assumption.
What is the real estate transfer tax rate in Germany?
The real estate transfer tax rate is set by the federal states and ranges from 3.5% to 6.5%. In North Rhine-Westphalia, it currently stands at 6.5%. In the case of a unified contract structure, this rate also applies to the construction costs.
When is there no uniform contractual arrangement despite the combination of a purchase and construction contract?
If the original general contractor agreement is amended in material respects after the property purchase contract is concluded, the assumption of a uniform contractual arrangement no longer applies. Material deviations include, for example, changes in floor area or construction costs of more than 10%, or the erection of an additional defining building. In such cases, real estate transfer tax is assessed solely on the value of the land.
What precautions should buyers take before signing a contract?
Before finalizing purchase and construction contracts, the draft should be discussed with a Rechtsanwalt (German Attorney-at-Law) or notary and submitted to the Steuerberater (German Certified Tax Advisor). This allows real estate transfer tax risks arising from a unified contractual arrangement to be identified early and, where possible, avoided through appropriate contract drafting.
