Fees & Costs
Transparent and Tailored to Your Needs
Fees are generally charged in accordance with the German Tax Adviser Remuneration Ordinance (StBVV). The specific fee depends on the service provided and the circumstances of your case, particularly the scope and complexity of the work. Complete and well-prepared documents can reduce the time and effort required.
For larger engagements, I can, upon request, provide an initial, non-binding estimate of the expected costs before you engage my services, based on sufficiently detailed documents.

Complete and well-prepared documents can affect the time and effort required.
If tax questions need to be discussed first or a more detailed understanding of your situation is required, a paid initial consultation may be helpful—for example, if prior-year documents are unavailable, you are starting a business or you are purchasing a rental property.
Depending on the nature and scope of the engagement, a fee agreement may also provide for a fixed fee for services whose scope can be reliably estimated, billing based on time spent at an agreed hourly rate, or a combination of both.
Further information is available in my information sheet Tax Advisor Fees (in German).
