Overview

IRS Form 3949-A, Information Referral, is used to report suspected tax violations, such as fraud or tax evasion, to the IRS. Form 3949-A plays a critical role in facilitating the detection and investigation of tax-related crimes, ensuring fairness and integrity in the tax system.

This ML package is trained on 31 regular data fields to extract the relevant data points from Form 3949-A.

This model was trained on all versions released by the IRS from January 2017 to present.

Particularities

The ML package is trained to automatically detect data such as:

Document Version
Individual Name, SSN, DoB, Address, Occupation
Business Address, Email, Website
Unreported Tax Year, Unreported Tax Amount
Bank Name, Address
Reporter Name, Phone

Extracted fields

Note: If you are using using public endpoints, such as https://du.uipath.com/ie/invoices, all fields are available. However, if you are using custom-trained extractors, the availability of extracted fields is dependant on the version you are currently using.

You can also check the list of fields and types on any endpoint in the /info/model object. To access this, simply add /info/model to any endpoint, like so: https://du.uipath.com/ie/invoices/info/model. For an enhanced reading experience of the fields list, it's recommended to install a JSON viewer extension in your browser.
