New Regime Tax Slabs FY 2026-27

Budget 2025 made the new regime much more attractive. Zero tax up to Rs.12 lakh (after rebate u/s 87A):

New vs Old Regime — Which to Choose?

  • Choose New Regime if: You have fewer deductions (no home loan, no big 80C investments). Income up to Rs.12L → zero tax!
  • Choose Old Regime if: You have home loan interest above Rs.2L, HRA benefit, lots of 80C investments. High earners with max deductions save more in old regime.
  • Break-even: If your total deductions exceed Rs.3.75 lakh, old regime may be better for income above Rs.15 lakh.
