TaxTobi.AI: crypto tax questions, answered with the source

TaxTobi is the AI assistant of Matthias Steger Consulting for the German taxation of crypto assets. It does not answer from the open internet but from a knowledge base we maintain in the practice: every answer with the legal basis, its date and, where one exists, a note on the dispute. The first question is free. It is not individual advice, and it says so. The knowledge base is in German; you can ask in English.

What TaxTobi can and cannot do

Can

Explain the law

  • Holding period, exemption limits, staking, lending, airdrops, cost-flow method, tax reports, voluntary disclosure, DAC8, inheritance: under German law, with the margin number of the ministry circular or the case reference.
  • Say where a point is disputed and which case is pending.
  • Decode terms in exchange exports, such as booking texts in a transaction history.
  • Around the clock, in seconds, first question free.
Cannot

Decide your case

  • No individual advice: TaxTobi does not know your documents and may not advise. That is tax advice and stays with us.
  • No foreign law: it does not answer questions on Poland, Austria or Switzerland.
  • No tax return, no calculation of your gain, no letters to the tax office.
  • No legal certainty: the ministry circular does not bind the courts and some points are open. TaxTobi names them; it cannot settle them.

Questions TaxTobi answers

Examples from our tests, not client data. Every answer names the source and the date.

  • Sec. 22 no. 3

    "Do I have to tax staking rewards when they are credited, and are they taxed again when I sell?"

  • Sec. 23

    "Do I have to use FIFO when selling, or may I use LIFO?"

  • Report

    "The tax office did not accept my tax report. What matters?"

  • Export

    "What does 'Merchant acquiring' with the note 'Binance Pay' mean in my Binance transaction history?"

Where it stops

"How is crypto income taxed in Poland?" is a question TaxTobi does not answer. It is limited to German law. For destination countries when leaving Germany we have our own articles.

Questions and answers

Is TaxTobi free?
The first question is free. After that the assistant can be used in full from €9.99; purchase runs through Digistore24. Term, number of questions and cancellation are stated on taxtobi.ai.
Does TaxTobi replace a tax adviser?
No. TaxTobi explains German law with its source, but it does not know your documents and may not give individual advice. Your own return, a voluntary disclosure or an exit from Germany need an engagement with us.
Where do the answers come from?
From a knowledge base we maintain in the practice: answer, legal basis, date and, where needed, a note that a point is disputed. The sources are the Finance Ministry circular of 6 March 2025, the case law and our own articles.
What happens if TaxTobi cannot answer?
The question is passed to the team. Registered users who have given their name receive a reply; we cannot reach guests without details. We do not promise a response time.
Does TaxTobi answer in English?
TaxTobi is built for German tax law; the knowledge base is in German. You can ask in English, but check the answer against our English articles, and for your own case talk to us: we advise in English.
Are my questions stored?
Chat histories are stored on taxtobi.ai. What exactly is recorded and for how long is set out in the privacy notice there. Do not enter anything in the chat you would not want to disclose; confidential documents belong in an engagement.
