The advantages of having a tax advisor at your side
Digital collaboration takes place via DATEV eG’s online applications. For you, this means:
- More time and less stress
- You don’t have to navigate tax changes on your own—I’ll keep track of everything for you
- Reliable deadlines and schedules: Filings, returns, and deadlines are monitored to ensure nothing is overlooked
- More flexibility with filing deadlines: As a client, you often benefit from extended filing deadlines
- Security during audits and inquiries: Practical experience helps avoid common pitfalls early on—including in the context of tax audits
- Planning certainty and clarity: You receive transparent, understandable assessments instead of unclear tax risks.
In short, less effort for you—more security, structure, and peace of mind in your day-to-day tax affairs.
Do you have questions about a specific topic?
Whether by email, phone, or video conference: you can reach me quickly and reliably.
Together, we’ll find the best time and format for your consultation.
✔ No-obligation initial consultation – a clear start, risk-free
✔ Discreet & GDPR-compliant contact

What does “100% digital tax consulting” mean?
Whether you’re at home, abroad, or on the go: You can handle all your tax matters entirely digitally and paperlessly — without travel time or extra steps.
Despite our digital approach, transparency and personal contact remain a priority: I serve as your dedicated point of contact, personally addressing your concerns.
How much does your tax consulting service cost?
My fees are generally based on the Tax Advisor Fee Regulation (StBVV). This regulation sets a binding fee schedule for many services—such as the preparation of tax returns or annual financial statements.
To enable better planning and for services whose fees are not regulated by law (e.g., business consulting), we often agree on a supplementary remuneration agreement – particularly for business clients or project-related services.
How do I become a client?
You can contact me at any time using my contact form.
Once I receive your inquiry, I will briefly review your request and suggest an appropriate course of action for the next steps. Depending on the situation, this may be, for example:
- directly requesting usual documents (e.g., latest tax assessment, current income statement) via DATEV Onboarding for an efficient mandate assessment
- an initial consultation to discuss specific tax issues in a structured manner
- A brief, free introductory meeting, if it makes sense to first gain a more detailed understanding of your situation
On this basis, we can decide together whether and to what extent (further) collaboration makes sense.
I look forward to hearing from you!
