March 2025: Delivered cross-repo improvements across hmrc/income-tax-property-frontend and hmrc/income-tax-property, focusing on auditability, expense data capture, and developer experience. The work enhances regulatory compliance, data integrity, and local deployment readiness, setting a stronger foundation for end-to-end property tax processing.

February 2025 highlights focused on strengthening the reliability and observability of the income-tax-property domain, with significant backend and frontend improvements for foreign property data handling and submission workflows. Key efforts included stabilizing tests by switching from Array to Seq, expanding data retrieval/merging/error handling logic, and enhancing observability to accelerate debugging of R15 foreign property data fetch failures. Across backend services and frontend UI, we delivered more robust data flows, richer telemetry, and clearer error reporting, translating into faster issue resolution and improved user journeys.

This month-focused summary highlights key business value delivered in January 2025 across two repos, emphasizing FE-BE data submission alignment, new data models, and backend endpoints to support annual submissions for foreign property allowances.

December 2024 focused on end-to-end enhancement of the foreign property income capability across frontend and backend, improving user journeys, data integrity, and submission reliability. Key frontend refinements included navigation and content updates for the foreign property income path, a new 'Allowances' branch, cleanup of dependent CYA data when options change, precise error message placement, and improved test coverage for navigation flows. On the backend, new data models and controllers were introduced to handle foreign income (including lease premiums and reverse premiums), bridging frontend-to-backend data flow. A dedicated BE endpoint and Mongo persistence layer were added to receive and persist foreign income data, with updates to submission flows and mocks/tests. An API-compatibility effort aligned submissions between UK Property and Foreign Property (oneOf) to prevent invalid mixed submissions. The Allowances feature gained a backend data model, persistence logic, and tests to support foreign property allowances. Across both repos, testing was expanded to increase coverage and robustness. Overall, these changes reduce user friction, increase data accuracy, and enable scalable growth of the foreign income capability.

November 2024 performance summary: Delivered a robust, end-to-end Foreign Property country selection experience across backend and frontend, with aligned routes and URL paths, improving user journey consistency and data integrity. Implemented FE-BE integration for saving journey state, including a Check Your Answers page, a completion flow, and UI status mapping (Complete/In Progress/Not Started). Extended the Foreign Tax journey with improved navigation and clarified form field handling, ensuring correct country code processing. Normalization of frontend storage and route refactors reduced complexity and facilitated reliable data retrieval. These changes enhance user completion rates, accuracy of tax property reporting, and maintainability of the tax property codebase.
