German freelancer tax filing automated end-to-end. Steuer parses your Wise bank statements into structured transactions, classifies income and expenses into German tax categories, converts USD to EUR using official ECB reference rates (with full audit trail), generates a Finanzamt-ready PDF + CSV for your Einnahmen-Überschuss-Rechnung, and walks you through filing via ELSTER line by line. All processing stays local — no data leaves your machine.
