Lending and Underwriting: Speed up loan approvals by extracting taxpayer details, verification requests, and income data from any Form 4506-C â€“ including scanned documents. Business-rule validation catches missing TINs, date inconsistencies, and incomplete verification requests before they slow down your pipeline.
Compliance and Audit Teams: Leverage AI that adapts to form variations and revision updates, ensuring accurate taxpayer information capture while maintaining audit trails and regulatory documentation standards.
Tax and Accounting Operations: Feed structured Form 4506-C data directly into your tax and compliance systems to support verification workflows, improve data accuracy, and scale operations without adding headcount.

What is a form 4506-C OCR data extractor?

A Form 4506-C optical character recognition (OCR) data extractor scans and accurately captures information from Income Verification Express Service forms, regardless of format or language. Upload Form 4506-C documents in PDF, JPG or PNG formats. The OCR technology first converts the documents into a text layer, ensuring all text (even from scans, photos, or handwritten entries) is captured. Affinda's AI models then identify and extract key fields such as taxpayer details, verification requests, reference numbers, tax years and data source selections, transforming them into structured, usable data.

This automation eliminates manual data entry, reduces errors and speeds up processing. Once the Form 4506-C data is captured and structured, our AI form 4506-C processing pipeline can apply machine validation and post-processing to enable seamless integration with lending, tax and compliance systems.

Organizations in lending, accounting, tax and compliance rely on Affinda's AI for their income verification and audit processes, streamlining workflows and improving overall accuracy.
