Frequently Asked Questions

What sets you apart from traditional tax due diligence advisors?

We keep tax due diligence focused on what really matters. Our reports are concise and decision-oriented, with all material tax risks brought together in a clear executive overview and supported by detailed analysis throughout the report. We quantify exposures wherever possible – using reasonable ranges where an exact amount cannot be determined – and clearly distinguish material risks from less relevant findings. This gives deal teams a quick and transparent view of the target’s tax risk profile and the potential financial impact.

When should we bring you in?

Ideally early, as soon as you receive initial information about the target or once a Letter of Intent has been signed. This allows us to define data requests and analytical priorities correctly from the start.

Are your reports bank-ready?

Yes. Our reports are prepared in Germany by Radial GmbH Wirtschaftsprüfungsgesellschaft and accepted by all major banks, supporting your M&A transactions and financing discussions with reliable, well-documented tax analysis.

What business models do you cover?

We generally cover all industry sectors, with the exception of banks and insurance companies.

How long does the project take?

Typically three to four weeks from kickoff to the final report. Complex M&A deals or broader due diligence scopes may require additional time, depending on data, jurisdictions, and transaction process dynamics.

What data do you need?

We generally require tax-relevant information for all open tax years, including financial statements, tax returns, tax assessment notices, transfer pricing documentation and documentation relating to historical reorganizations. We prepare a detailed request list for you.

Do you work with other advisors?

Yes. We coordinate closely with your legal, financial, and strategy advisors.

What are the main objectives of buy-side tax due diligence?

The objective of a buy-side tax due diligence is to provide buyers with the information required to assess historical and future tax risks, make informed investment decisions, and negotiate appropriate purchase price adjustments and contractual protection.
