How Old vs New Tax Regime Calculator FY 2025-26 is Calculated

The calculator applies old regime tax slabs (with all eligible deductions like 80C, HRA, 80D, NPS) and new regime slabs (with limited deductions but lower rates), then shows tax payable under each and recommends the better option.

Worked Example

Income ₹15,00,000 with ₹3,50,000 in deductions (80C + HRA + NPS): Old regime tax ≈ ₹1,87,200. New regime tax ≈ ₹1,56,000. New regime saves ₹31,200 in this case.

Common Use Cases

• Annual tax regime selection
• Evaluating deduction benefits
• Salary restructuring decisions
• Financial planning for FY 2025-26

Common Mistakes to Avoid

• Using outdated tax slab rates — the new regime slabs changed significantly in the Union Budget 2024. Always use the latest rates for FY 2025-26.
• Forgetting the ₹75,000 standard deduction now available under the new regime — this reduces the breakeven point for choosing between regimes.
• Not including employer NPS contribution (up to 14% of salary) which is deductible under both regimes.
• Comparing regimes without including all deductions — HRA, 80C, 80D, home loan interest, and NPS must all be factored in for accurate comparison.
