Consulting

Tax planning advice and assistance with business and tax-related issues.

Sound advice based on up‑to‑date data

To help you make well‑founded tax and business decisions, I base my recommendations on current specialist literature, case law and extensive tax and economic databases (including Beck Steuerrecht PREMIUM, Haufe Steuer Office Excellence, DATEV LEXinform comfort).

This allows us to draw on industry benchmarks, regional location data and specialised practical tools in a targeted way – so your planning is not based on “gut feeling”, but on reliable figures and up‑to‑date court decisions.

Note: At present, I am unable to take on engagements involving highly cash‑intensive business models, complex e‑commerce structures or matters in the area of tax criminal law.

Digital Collaboration

Collaboration takes place entirely digitally via MyDATEV. Receipts, reports, documents, and messages are available there in a centralized, secure manner, accessible from anywhere. This ensures that processes remain clear, efficient, and transparent.

Handle your bookkeeping yourself – with my support

Would you like to handle your tax records or bookkeeping yourself during the year? For start-ups and self-employed individuals with a manageable volume of business transactions, Lexware Office may be a suitable option. As a new client, I can often provide you with a complimentary 12-month licence as part of an ongoing engagement.

Your path to collaboration

You can start by sending me a message or directly request an introductory call.

For one-off advisory enquiries, the process is even simpler: simply book a consultation appointment directly via my online calendar.

If a longer-term engagement is being considered, the engagement process is handled digitally. You’ll receive the necessary engagement documents electronically via FP Sign—no registration required. 

As a service, I provide three fee calculators for typical services such as bookkeeping, income tax returns, and annual financial statements, together with further information.

I look forward to receiving your non-binding inquiry.
