​
Key Features

Form 16 Extraction

Extract salary details, TDS information, and investment declarations from employer-issued TDS certificates.

Form 26AS Extraction

Extract creditable TDS amounts, deductor details, and tax payment information from annual TDS statements.

High Accuracy

Advanced AI models with confidence scoring ensure reliable data extraction from various document formats.

Bulk Processing

Process multiple documents asynchronously with job-based processing for scalability.

​

Best Practices

  • Document Quality: Upload clear, well-lit scans or digital PDFs for best extraction results
  • Complete Documents: Ensure all pages are included for multi-page documents
  • Metadata: Provide taxpayer PAN and financial year for better validation
  • Confidence Thresholds: Set appropriate confidence thresholds based on your use case
  • Validation: Always validate extracted data, especially for high-value decisions
The APIs support PDF documents and common image formats (JPEG, PNG). For best results, use original digital PDFs rather than scanned images.
Accuracy varies by document quality and type, but typically ranges from 85-95% confidence. Each extracted field includes a confidence score for validation.
Yes, the APIs support async job-based processing for bulk document processing. Submit multiple documents and track progress via job status endpoints.
Fields with low confidence scores are flagged in the response. You can set minimum confidence thresholds or implement manual review workflows for critical data.
Individual documents should be under 10MB. For larger files or bulk processing, contact support for optimized processing options.
