German crypto taxes,
built for DeFi power users

We reconcile every swap, bridge, LP and lending move across your wallets into one clean, audit-ready gains & income report.

Jurisdiction: 🇩🇪Germany

Germany only for now — Australia, Spain & UK on the way. DE output: Anlage SO (§23 & §22 EStG).

Public wallet addresses only — we never ask for your private keys or seed phrase.

THE PROBLEM

Ordinary calculators are built for swap-only wallets.

Throw real DeFi at them — bridges, lending, loans, loops, restaking — and the numbers quietly fall apart.

ordinary-tool-export.csv

12 misbookings

Aave · borrow 10 ETH booked as taxable income

Bridge ETH → Arbitrum counted as profit

Transfer to your own wallet taxed as a disposal

Wrap ETH → WETH taxed as a disposal

Pendle · Morpho · restaking dropped to unknown

Result: phantom gains and a report you can't trust.

WHY MYDEFITAX

Built native for DeFi professionals.

For people who bridge, lend, borrow, LP, restake and loop — not just swap. Every shape is understood, none booked as phantom income.

No phantom income

Loans, bridges, wraps and self-transfers are understood — never taxed as profit you never made.

Audit-ready by design

Every number traces back to the exact on-chain event behind it.

Right §, right year

Income and gains booked under the correct paragraph and the correct tax year.

Know before you file

A confidence score flags exactly what needs a second look — before you submit.

Coverage that keeps up with you.

We natively model the protocols, chains and (soon) exchanges you actually use — not just the simple swaps.

VERIFY

Know when it's ready to file.

A confidence score reads every wallet and tells you what's solid and what needs a look — in euros, not vague flags. You file when it says ready.

READY TO FILE / NEEDS REVIEW verdict

Allowances & holding periods applied automatically

Per-wallet, money-at-risk scoring

AUDIT TRAIL

Every disposal, traceable.

Each gain ties back to the exact lots it consumed and the on-chain event behind it — short vs long term, per chain, fully auditable.

Portfolio-wide FIFO — buy on one wallet, sell on another

Proceeds & cost basis on every row

Filter by year, chain and term

CLASSIFIED LEDGER

Every action, understood.

40,000+ raw movements turned into clean economic actions — swaps, bridges, lending, repays — so nothing silently lands in 'unknown'.

Bridges & self-transfers netted out

Loans & repays booked correctly

Wraps and receipts recognized
