Habenseite
Professional Austrian personal finance platform. T-Konto bookkeeping, AI-powered tax calculators (12 categories), official 2026 tax constants, and share links — built for serious money management.
Habenseite is the professional spin-off of FinanzJesus — same engine, no comedy. Built for Austrians who want serious, accurate personal finance tooling without the noise.
At its core is a T-Konto interface: the classic debit/credit ledger view that accountants actually use, rebuilt for personal use. On top sits a suite of 12 AI-powered tax calculators covering the key Austrian tax scenarios — all grounded in official 2026 tax constants sourced directly from the Finanzamt. Every calculator result is shareable via a permanent link, making it easy to export a calculation for your tax advisor or accountant.
The platform includes a full Playwright test suite (17 tests), an AI spend circuit breaker to cap LLM costs in production, and is deployed on Railway. The brand runs independently from finanzjesus.app with its own domain, identity, and storage namespace.
