Worked on the PolicyEngine/policyengine-us repository to deliver the Oklahoma 2024 Tax Year Data Update, aligning tax parameters with the latest forms, thresholds, and statutory references. Focused on data management and documentation, the update included revising YAML-based configuration files to reflect current tax policy and updating URLs for 2024 tax forms while correcting outdated links for prior years. Added a detailed changelog entry to enhance traceability and compliance, supporting auditability of tax code changes. The work improved the accuracy of Oklahoma tax calculations and ensured that reference data remains current, demonstrating attention to detail in tax policy implementation and documentation.
