Local W-2 Data Extraction

From 53 Hours of Manual Extraction to 203 Minutes of Automated Processing

A law firm regularly receives batches of W-2 forms from which it must extract structured data. Over the course of a year, the firm may process many thousands of records, with source documents arriving in different formats and containing both text-based and scanned pages.

For one representative project, the firm received a file containing 3,177 individual W-2s. At an estimated one minute of manual extraction per record, processing the file would have required approximately 53 hours of staff labor.

FortisWorks developed a customized, standalone application that completed the same extraction work in 203 minutes—3 hours and 23 minutes—on a client laptop with 32 GB of RAM. An employee spends only a few minutes launching the process: copy the PDF into the input folder, double-click Extract, and return later to find the extracted data in the output folder.

Purpose-Built for the Workflow

The application handles differing W-2 formats and extracts the information needed by the firm:

• Employer name, Employer Identification Number (EIN)

• Employee name, Employee Social Security number

• Box 1, Box 3, Box 5, Boxes 12a–12d

The extracted records can be written to a CSV file or inserted into a local database. The application skips pages that are not W-2s and flags records with missing required fields or questionable values for human review. It can also produce processing logs when the firm wants an audit or troubleshooting record.

Local Data Processing

The application is installed on hardware controlled by the client. Internet access is needed during the initial installation to download required supporting libraries. After installation:

• Document processing occurs entirely on the user’s computer

• W-2 data is not uploaded to FortisWorks

• Documents are not submitted to cloud-based AI or document-processing services

• The application makes no external calls during normal processing

• Results remain within the client’s local environment

This deployment model gives the firm direct control over sensitive employee and tax information while avoiding dependence on an externally hosted processing service.

A Repeatable Process

The result is a repeatable internal workflow that replaces record-by-record data entry with a largely unattended process while preserving human review for exceptions. 

FortisWorks provides custom development, installation, user training, ongoing support, and maintenance for focused software tools like this one. The same approach can be applied to other repetitive document-processing, billing, reporting, data-entry, and file-routing workflows where privacy, control, and predictable operation matter.
