Who Should Choose Which Regime?

Choose Old Regime if

  • You have significant investments in 80C (PPF, ELSS, Life Insurance)
  • You pay house rent and claim HRA
  • You have a home loan (interest deduction up to ₹2L)
  • You have health insurance premiums to claim under 80D
  • Total deductions exceed ₹2 lakh

Choose New Regime if

  • You have minimal investments and deductions (less than ₹2L)
  • You prefer simplicity with less paperwork
  • You don't get HRA from employer
  • You're a young professional just starting career
  • You want to avoid hassle of maintaining investment proofs
