Development of a Real-Time Social Security Calculator
Our team was approached by a finance and tax advisory firm specializing in self-employed professionals in Portugal. Their goal was to create an intuitive, user-friendly digital tool that helps freelancers and independent professionals quickly and accurately forecast their social security contributions under Portugal’s Recibos Verdes (self-employment) tax regime.
Hyrdle collaborated with a client to create an intuitive web application designed to assist self-employed professionals in Portugal with accurate social security contribution calculations, adhering to the country’s 21.4% contribution rate.
Project Objectives: • Accurate Contribution Calculations: Ensure precise computations based on Portugal’s social security regulations. • Customizable Forecasting: Allow users to adjust variables such as income and optional reductions to project future contributions. • Responsive User Experience: Develop a mobile-friendly platform supporting real-time calculations for ease of use.
Key Features Implemented: 1. Interactive Contribution Forecasting: • Users can input quarterly earnings, select optional social security reductions (ranging from 5% to 25%), and estimate business expenses. • The system calculates relevant income (70% of service revenue), adjusted contribution base after reductions, and total social security contributions per quarter and per month. 2. Dynamic User Experience: • Features instant tax calculations with live updates, dark mode, accessibility options, side-by-side scenario comparisons, and multilingual support in English and Portuguese. 3. Scalable & Secure Backend: • Utilized React.js for the frontend and a Python Flask API for calculations, hosted on AWS and Vercel for optimal performance. • Implemented secure input validation, lightweight API for fast responses, and GDPR-compliant data handling. 4. PDF & Email Report Generation: • Enabled users to download detailed tax forecast PDFs and receive comprehensive breakdowns via email for tax planning purposes. 5. Expansion Potential: • Designed the system to be modular and scalable, allowing future integrations with Portugal’s Segurança Social API for real-time tax updates, banking and accounting software for automated reporting, and AI-powered tax optimization recommendations.
Results & Impact: • Accuracy: Achieved 100% accuracy in social security contribution calculations based on Portugal’s latest tax laws. • Efficiency: Streamlined financial planning for self-employed professionals, eliminating manual tax estimations. • User Engagement: Enhanced user engagement through a seamless, interactive user experience. • Client Growth: Contributed to the client’s revenue boost through increased consultations and financial service upsells.
Future Development:
Plans include exploring automated tax filing integration and AI-driven advisory features to further enhance the platform’s capabilities.
