The ₹12 Lakh Zero-Tax Announcement — What It Really Means

The Finance Act 2025 made one of the most significant personal tax changes in a decade: zero income tax for individuals earning up to ₹12 lakh under the New Regime. For salaried employees, this limit is effectively ₹12.75 lakh after the ₹75,000 standard deduction.

Bottom line: If you earn ₹12 lakh or less, you pay zero tax in FY 2025-26 under the New Regime. No investment required, no proofs needed.

Taxable Income₹9,25,000
Tax Payable₹44,200

New Regime saves ₹15,600 — even though Rahul is claiming full 80C + NPS deductions!

When Does Old Regime Win?

The Old Regime wins only when your total deductions exceed ₹3.75 lakh for ₹10L income. This typically means you have:

  • HRA of ₹25,000+/month (big metro rent)
  • Home loan interest under Section 24(b)
  • Full 80C + NPS + Health insurance

Quick test: Add up your Standard Deduction + 80C + 80D + HRA + home loan. If the total is above ₹3.5 lakh, calculate old regime. Below that — go New Regime.
