Old and new tax regime calculator
Help a salaried person choose between the old and new income tax regimes with their own numbers.
The brief
Every year salaried people guess which regime saves more. Build a calculator that takes salary, allowances and deductions (80C, HRA, home loan interest and others), computes tax under both regimes for the current rules, and shows the break-even where one becomes better. Good looks like: results that match the official calculator on 20 test cases, clear assumptions, and a chart of tax against income for typical deduction levels.
What you will build
- Read the slabs, rebate and deduction rules for the year
- Code both regimes
- Add HRA and the common deductions
- Check results on 20 cases against the official calculator
- Find the break-even deduction level
- Build a simple web or spreadsheet tool
