What does “100% digital tax consulting” mean?
Whether from home, abroad, or on the go: You can handle all your tax matters completely digitally and paperlessly—without travel time or delays.
Despite our digital approach, transparency and personal contact remain a priority: I serve as your dedicated point of contact, personally addressing your concerns—by phone, email, or video conference.
How much does tax consulting cost?
Fees are generally charged in accordance with the applicable statutory provisions.
In individual cases, a fixed fee or an hourly rate may be agreed, depending on the scope and complexity of your matter.
For more information, please visit my Fee Information page.
Is there a fee for the initial meeting?
An initial introductory call (up to 20 minutes) is, of course, free of charge and without obligation.
A fee applies to an initial consultation in which we discuss specific individual tax questions or already go into the details of your case.
Who is your tax firm best suited for?
For business owners (partnerships, corporations, and sole proprietorships) and individuals with income from employment, rental properties, or investments who want to work digitally and value a strategic approach.
How can I become a client?
You can contact me via the contact form, by email, or simply by phone.
After our initial meeting, you’ll receive all the necessary documents to get started—digitally and hassle-free. In simpler cases, we can begin preparing your tax return right away, if you wish.
In other cases, we’ll start with an in-person initial consultation—tailored to your needs and at a pace that works for you.
Efficient, personalized, and always on equal footing.
Can you also assist me in English?
Yes. I speak English fluently and I am happy to assist you with all matters of national and international tax law, especially if English is your first language.
Do I have to have them handle my bookkeeping?
No. If you already have sufficient experience and established processes in place, I can also provide you with targeted support in preparing annual financial statements and tax returns.
For self-employed individuals, I can often arrange for you to use Lexware Office free of charge for up to 12 months. For corporations and larger or more complex sole proprietorships, a different accounting solution may be more appropriate if Lexware Office’s capabilities are insufficient.
Regardless of the software used, the following applies: Efficient processes create room—for personalized support, strategic advice, and entrepreneurial thinking.

Would you like to get to know me as your tax advisor, or do you have a specific tax question? Feel free to briefly tell me what you need assistance with. You can use my contact form or email me at info@stb-kather.de.
I will then get back to you and discuss the next steps with you. Depending on your enquiry, I may first ask you a few follow-up questions, or you may be able to schedule a short, no-obligation introductory call directly. If needed, I often request additional information and documents conveniently via DATEV Onboarding.
Do you have a specific tax question and are you unlikely to need ongoing support? You can book an online consultation directly through my online appointment calendar.
I look forward to hearing from you.
