Tax law for real estate investments
Real estate is a central component of strategic asset allocation. We support the entire life cycle of your real estate project — in Germany and across borders. In doing so, we combine expertise with efficient processes.

Tax Compliance & Filings
Depending on the investment structure, tax regulations, deadlines and documentation requirements change. We translate the structure into a clean declaration and documentation and keep an eye on the typical points of contention.
Our services:
- Compliance: financial accounting, financial statements, tax returns
- Structure: Appropriate declarations for private individuals, companies, real estate companies and funds
- Sustainable positions: Well justified and reliably documented
- Operational audits: Support of tax audits, appeal and tax court proceedings
- Valuation: Property valuation in accordance with the German Valuation Act
- Classification: Classification and differentiation of asset management versus commercialism
- Review: Review and documentation of often contentious scenarios (including real estate trade, division of businesses, ancillary services)
Tax due diligence
We analyse the relevant information in the shortest possible time. Our due diligence addresses the investment structure and transaction type. We are also happy to provide expert opinions on individual topics.
Our services:
- Due diligence reports for buyers or sellers
- Red Flag Reports for time-critical projects
- Second Opinions resp Expert Opinion, in particular on critical issues (e.g. VAT and trade tax)
Property Valuation
Property valuation is of paramount importance in tax law. We are familiar with typical use cases both for transactions and trust and estates (gift and inheritance tax).
Our services:
