Both regimes tax income progressively โ each slab's rate applies only to the portion of income within that band, not your entire income. The figures below reflect FY 2026-27; always cross-check against the Income Tax Calculator or the Old vs New Tax Regime comparison before filing, since Budget announcements can shift these figures.

The right choice depends almost entirely on how much you claim in deductions under the Old Regime. As a rough rule of thumb: if your total Old Regime deductions exceed roughly Rs 3.75-4 lakh, the Old Regime usually wins; below that, the New Regime's lower rates and higher rebate ceiling typically come out ahead. Run both scenarios through the Income Tax Calculator with your actual numbers rather than relying on the rule of thumb alone.
