AI-Powered Tax Document Analysis
Integrated with Europace, Baufinex, and Starpool to deliver intelligent document analysis using advanced AI models for accurate tax calculations and financial data extraction from German tax documents.
The Challenge
Building an AI-powered tax document analysis system that accurately processes German financial documents and provides intelligent tax calculations.
German Tax Document Processing
Handling various German tax document formats (BWA, tax assessments) with different structures, terminology, and data presentation styles.
Text Extraction from Scanned Documents
Extracting text from both digital PDFs and scanned documents with varying quality, requiring OCR fallback mechanisms.
Accurate Financial Data Extraction
Ensuring accurate extraction of financial metrics (pre-tax profit, tax paid, health insurance) from unstructured document text.
Multi-Year Tax Projections
Calculating accurate tax projections for the current year based on historical data from multiple previous years.
Our Solution
We developed a Flask-based AI service using advanced AI models with structured output schemas. The system implements dual text extraction, intelligent document type detection, comprehensive data validation, and sophisticated tax calculation logic for accurate financial analysis.
