➡ Under New Regime:

0% tax on ₹3,00,000 = ₹0
5% tax on next ₹4,00,000 = ₹20,000
10% tax on next ₹1,00,000 = ₹10,000
Total Tax = ₹30,000

➡ Under Old Regime (Assume deductions claimed = ₹1,50,000):

Taxable Income = ₹8,00,000 – ₹1,50,000 = ₹6,50,000
5% on ₹2,50,000 = ₹12,500
20% on next ₹1,50,000 = ₹30,000
