During December 2024, this developer updated the childcare allowance rates for 2025 and 2026 in the hmrc/childcare-calculator-frontend repository, focusing on configuration management to ensure calculation accuracy and policy compliance. The work involved introducing new rate structures within the configuration, allowing the calculator to reference current rates for all relevant age and job groups. By modeling policy data directly in the frontend and maintaining traceable, well-documented commits, the developer reduced the risk of outdated calculations and improved reliability for end users. The project emphasized configuration-driven rate management and policy data modeling, with no major bugs reported during this period.
