Worked on the PolicyEngine/policyengine-us repository to enhance payroll tax calculation accuracy, focusing on IRS compliance for FICA wage reporting. Addressed a critical bug by introducing a configurable parameter in Python and YAML that correctly excludes traditional 401(k) and 403(b) retirement contributions from gross wage calculations. This adjustment ensured that Social Security and Medicare wages align with IRC 3121(a) requirements, reducing the risk of underreported taxes. The solution included robust test coverage and clear documentation through pull requests, demonstrating careful backend development and collaboration. The work improved payroll tax logic, supporting accurate wage base calculations and consistent compliance for users.
