All wallets together. The limits apply to everything you hold, so this is the view that counts.

Wallets

Three sample wallets, run through the tax engine as this page loaded. Pick a card to see one alone, or paste your own address into the first.

Read by rules

Every transaction, through every step

The payload from the chain, what moved, the legs, the euro value, the tax: each transaction takes the same steps, and none of them is hidden. Open a row and follow it through all of them, down to the raw payload.

  • HeliusEvery transaction of the wallet, read once and kept
  • CoinGeckoA euro price at the minute it happened, from the market or the pool it traded in
  • ECBThe dollar turned into euros at the day's reference rate

Provisional: 2 open questions still move it.

Asked, never guessed

What the rules cannot tell, you answer once

A transaction the rules cannot explain becomes a question, not a guess. The ones that look alike come as one card, so one answer settles all of them. Each answer says what it means for your tax, and the investigator reads the wallet's history around it to tell you what most likely happened.

Program

What happened to the 10,000 tokens you sent FYfW7Y…eBxr each time?

Eleven times you sent 10,000 of a 10K.world token to an account this program opened. Each time the 10,000 came back a day or a few later, with more on top.

Every one of these went into an account FYfW7Y…eBxr opened for that deposit alone, and every time the same 10,000 came back from it, with more from the token's own reward account. The accounts are all closed now. Nothing was sold: this reads as locking the tokens for a reward.

The report

Two figures a year, and the reasons for both

Each year ends in what Anlage SO asks for: the gains from private sales under § 23 and the income under § 22 Nr. 3, each held against its limit. Every row says which rule read it, and every rule cites the BMF letter of 6 March 2025 down to the paragraph. Tap a paragraph to read it.

    • Disposal. A swap, a sale or a payment disposes of what was given. Gains within one year of acquisition are taxable. Rn. 53, 54
    • Proceeds. Proceeds are the market value of what was received, or of what was given when the received has no price or the disposal was a payment. Rn. 58, 60
    • First in, first out. Lots are kept per wallet and token; the first acquired is the first disposed. Rn. 61, 62
    • Holding period. The year runs from acquisition to disposal and restarts at every exchange. Wallet times count for direct trades. No ten-year rule. Rn. 55, 63
    • Fees. Fees paid to dispose are Werbungskosten, and count only against taxable disposals. Rn. 57, 59

        moved from your main wallet with 855.00 of cost, the lots keeping their dates

        The rules are public

        The engine's manual is built from what its tests run: each rule on its own page, with the real transactions or the typed histories that pin it. A rule nothing pins is not in the product.

        What it does today

        • Solana wallets. Coinbase is the next source.
        • German tax, after the BMF letter of 6 March 2025.
        • The report on screen. A PDF, and the rows as a CSV for a Steuerberater, come next.

        What it is not

        TaxMaxi is software. It computes figures from your wallets, your answers and the rules it shows you. It is not tax advice under the Steuerberatungsgesetz, and it does not replace a Steuerberater.
