@ittybit It is not on paper. In reality, if you are an honest person, new regime will save you money if your salary is more than 15 LPA.
If you can do shady shit like donate to political party and get koney back as cash or declare that you paid an absurd rent to your parents (no normal landlord will give you their PAN to claim 30k/month rent payment , unless they are NRI).
You can try to claim for disabled relative care. But if IT Dept or your company asks you for proof, you can get shafted. Many Infy employees were fired after they used these under hand tactics (idea given by some CA in Hyderabad or Bangalore) to claim refund during ITR filing. IT dept sent notice to Infy to get details.
For loans, you can claim deduction only on the interest payment part.
A colleague who got a pay hike to 18 LPA switched to New Regime as even after paying EMI for 50 Lakh Home Loan, he could not get enough exemption to get advantage in Old Regime.
