4. Example Income Tax Calculation
Let’s assume:
Annual Income = ₹10,00,000
Deductions under 80C = ₹1,50,000
Tax Regime = Old Regime
Step 1: Calculate Taxable Income
₹10,00,000 – ₹1,50,000 = ₹8,50,000
Step 2: Apply Old Regime Slabs (Illustration)
Up to ₹2,50,000 = Nil
₹2,50,001 – ₹5,00,000 = 5% → ₹12,500
₹5,00,001 – ₹8,50,000 = 20% on ₹3,50,000 → ₹70,000
Total Tax = ₹82,500
Step 3: Add 4% Cess
4% of ₹82,500 = ₹3,300
Final Tax Payable = ₹85,800
This amount is your estimated income tax liability for the financial year.
