About the Tax Planning & Optimization Tool
Our free Tax Planning & Optimization Tool helps salaried professionals and individual taxpayers in India compare tax liabilities between the Old Tax Regime and the New Tax Regime, while maximizing deductions across key sections like 80C, 80D, NPS, and home loan interest.
1. Tax Planning & Optimization Mathematical Formulas
Income tax liabilities under the Old and New Tax Regimes are computed using statutory tax slabs, standard deductions, and eligible Chapter VI-A deductions:
Old Regime Net Taxable Income = Max(0, Gross Income − Standard Deduction (₹50,000) − Total Eligible Deductions (80C + 80D + 80CCD(1B) + Sec 24b))
New Regime Net Taxable Income = Max(0, Gross Income − Standard Deduction (₹75,000))
Tax Liability = Progressive Slab Calculation + Health & Education Cess (4%)
Optimized Tax Liability = Min(Old Regime Tax, New Regime Tax)
Where the defined variables are:
- Gross Annual Salary / Income: Total yearly earnings before deductions.
- Eligible Deductions (Old Regime): Tax-saving investments and expenses under Section 80C (up to ₹1.5L), 80D, NPS 80CCD(1B) (up to ₹50k), and home loan interest Sec 24b (up to ₹2L).
- Tax Regimes: Progressive tax slabs under both frameworks, including Section 87A rebates where applicable.
2. Practical Worked Example
Let us review a standard tax comparison scenario with ₹15,00,000 gross annual income:
- Gross Annual Income: ₹15,00,000 (₹15 Lakhs)
- Section 80C Investments: ₹1,50,000
- Section 80D Health Insurance: ₹25,000
- NPS Tier-I Contribution: ₹50,000
- Home Loan Interest (Sec 24b): ₹2,00,000
- Total Eligible Deductions (Old Regime): ₹4,25,000
Calculation Breakdown:
- Old Regime Taxable Income = ₹15,00,000 − ₹50,000 (Std Ded) − ₹4,25,000 (Deductions) = ₹10,25,000 ($\rightarrow$ Old Tax Liability $\approx$ ₹1,17,000)
- New Regime Taxable Income = ₹15,00,000 − ₹75,000 (Std Ded) = ₹14,25,000 ($\rightarrow$ New Tax Liability $\approx$ ₹1,17,000)
- Comparison: Both regimes result in equivalent tax liability for this exact threshold, giving taxpayers flexibility.
Comparing both tax regimes annually ensures you select the optimal structure to minimize your tax outflow!
