When your bank requires a proof of funds
Bank inquiry, account freeze, verification requirement — TX-Partner delivers reliable crypto accounting for external compliance requirements.
When the tax authority sends a crypto inquiry
Supplementary request, inquiry letter, follow-up demand — TX-Partner prepares the data foundation for your response to the authority.
When you plan a voluntary disclosure
Complete crypto history as a prerequisite — TX-Partner reconstructs what is missing before the voluntary disclosure is filed with your tax advisor.
When your crypto tax tool shows errors or warnings
Unlinked transactions, negative balances, errors in tax report, unlabeled transactions — TX-Partner analyzes the root cause and resolves it systematically in your setup.
TX-Partner analyzes the root cause. The transaction history is fully prepared — missing imports, DeFi activities, bridge transactions, tool errors. Tool-agnostic, audit-ready, personally supervised.
Bookkeeping leads to complete crypto accounting. And the crypto accounting is the foundation everything builds on.
Root-cause analysis instead of symptom fix
Why data is missing — not just where.
On-chain analysis (wallet analysis)
When API/CSV imports are incomplete.
Reconstructing crypto history
Bridge transactions, old exchange data, missing custody periods.
Fixing tool errors
Negative balances, unlinked transactions, unlabeled transactions.
DeFi, bridges, multi-chain
Complex scenarios standard imports don’t cover.
Audit-ready for tax advisors & authorities
Reliably prepared for external review.
Tool-agnostic
