Tax: ₹12,500 + ₹40,000 = ₹52,500

New Regime Calculation:
Taxable Income: ₹8,00,000 - ₹75,000 (std. deduction) = ₹7,25,000

  3. Mid-Year Switch Not Allowed: You cannot change regime after filing your ITR for that year.
  4. Future-Proof Your Decision: Consider your 3-5 year plan. Will you buy a house? Start a family? These impact your deductions.
  5. Employer TDS: Tell your employer your preference at the start of the financial year to ensure correct TDS deduction.
