Old vs New Tax Regime 2026: Which One to Choose (Quick Decision Guide)
Updated July 2026
Short on time and just want the answer for 2026? This is the fast track. Below are the correct FY 2025-26 / AY 2026-27 slabs (which Budget 2026 left unchanged), a 30-second decision rule, and a link to run your own numbers. For the full, deep-dive comparison — worked examples at every income level, break-even deduction tables, surcharge, and switching rules — see our complete guide: Old vs New Tax Regime: Which One Should You Choose?.
The 30-second answer: If you're salaried, earning up to ₹12.75 lakh, and don't have big deductions like a home loan and high rent — the new regime almost certainly wins (often ₹0 tax). Have large deductions? The old regime may still edge ahead. When in doubt, compute both in our Regime Tax Calculator.
Key Takeaways
- New regime is the default (Section 115BAC) for 2026 — you're on it unless you opt out.
- Zero tax up to ₹12 lakh taxable income (₹60,000 Section 87A rebate); ₹12.75 lakh for salaried after the ₹75,000 standard deduction.
- Old regime is unchanged — ₹2.5L exemption, ₹50,000 standard deduction, and the full deduction menu (80C, 80D, HRA, home loan interest).
- Rule of thumb: modest deductions → new regime; large deductions (roughly ₹4.5 lakh+ at higher incomes) → check the old regime.
- Budget 2026 changed nothing — these numbers apply to FY 2025-26 and FY 2026-27.
- Don't guess a filing decision — run both regimes with your exact figures.

The 2026 Decision Checklist
- Are you salaried and earning ≤₹12.75 lakh? → New regime almost always wins (likely ₹0 tax). Done.
- Do you have a home loan + high rent (HRA) + maxed 80C/80D? → Model the old regime; it may still win.
- Not sure? → Run both in the Regime Tax Calculator with your real numbers.
- Check your take-home either way with the in-hand salary calculator or the CTC calculator.
- Re-check every year — your rent, loan, and investments change, so the right regime can too.
