📖 Overview

TaxScale is a Full Stack Web Application that helps salaried individuals make informed tax decisions by automating income tax calculations.

The application extracts salary information from Form 16 or accepts manual salary details, calculates tax liability under both the Old and New Income Tax Regimes, and recommends the more beneficial option.

The tax calculation engine is configuration-driven, allowing tax rules to be updated every financial year without modifying the application's business logic.
