Custom Tax Documentation in Workday Using BIRT: Challenges and Solutions in W-2 and 1095-C Report Design

Designing tax documents like W-2 and 1095-C in Workday using BIRT introduces both technical complexity and regulatory sensitivity. This paper examines the challenges and practical solutions associated with creating compliant, customizable tax forms within Workday’s reporting ecosystem. It focuses on how organizations can meet the dual demands of IRS-mandated accuracy and employer-specific branding or formatting requirements. Core challenges discussed include dynamic population of box-level data, managing federal and state-specific variations, conditional field display logic, and year-end updates from the IRS. The paper explores how BIRT’s layout engine can be used to manage these complexities through parameterized templates, calculated fields, and custom expressions. Real-world examples demonstrate the handling of edge cases such as multiple state wages, corrections (W-2c), and ACA reporting thresholds. Also highlighted are strategies for secure distribution through Workday's document delivery framework and user access controls.
