About Nadja

Nadja studied finance and tax law and writes the tax part of this site.

Her subject is the framework: why winnings fall under no category of income for a private player, and where the line to commercial activity runs.

For cryptocurrency she explains the second event — the disposal — and why documenting every movement decides everything.

Promises of tax-free money do not appear in her texts; the “strategies for tax-free winnings” published here before have been removed.

Every legal statement carries a date, because the position in 2026 is not the position of 2021.

Her aim is that readers can look up their own situation instead of trusting a summary.

How these articles are made

  • Every legal statement dated, because the rules change
  • No advice: the articles explain the framework, not a case
  • No promises of tax-free money — only what can be looked up
„A euro you overpay in tax is a euro you never had to lose. My job is to prevent that.“ – Nadja Brenner

Frequently Asked Questions

How long has Nadja been writing on this site?
Her articles here carry their own dates. She is not part of an operator’s staff — this site is an independent overview.

What does Nadja Brenner specialise in?
The tax framework for gambling winnings and cryptocurrency in Germany.

Does she offer individual tax advice?
No. She explains general principles; your own case needs professional advice.

Are winnings at this brand unproblematic for tax?
The question cannot be answered: there is no working operator behind this brand and therefore no statement of account. In general, winnings are not subject to income tax for a private player, and with crypto the disposal of the currency is a second event.

Can you write to Nadja with tax questions?
She picks up general questions in articles; that is not advice on an individual case.
