New vs Old Tax Regime for FY 2026-27 — slab comparison, deductions lost, breakeven points and a clear decision framework for salaried taxpayers.
The choice between the old and new tax regimes has become sharper with every Finance Act, and for FY 2026-27 the new regime sits as the default — you must consciously opt for the old regime if you want to keep claiming most exemptions and deductions. With Section 87A pushing the new regime's zero-tax band to ₹12 lakh and the ₹75,000 standard deduction for salaried taxpayers, choosing the wrong regime can quietly cost you tens of thousands of rupees a year.
New Tax Regime Slabs for FY 2026-27
The new regime offers a simplified slab structure: nil up to ₹3 lakh, then 5 per cent, 10 per cent, 15 per cent, 20 per cent and 30 per cent in widening bands going up to ₹15 lakh and above. The Section 87A rebate ensures effectively zero tax up to ₹12 lakh total income. Standard deduction of ₹75,000 applies to salaried taxpayers; family pension recipients get ₹25,000.
- Up to ₹3,00,000: Nil
- ₹3,00,001 to ₹7,00,000: 5%
- ₹7,00,001 to ₹10,00,000: 10%
- ₹10,00,001 to ₹12,00,000: 15%
- ₹12,00,001 to ₹15,00,000: 20%
- Above ₹15,00,000: 30%
Old Tax Regime Slabs
The old regime preserves the broader deduction architecture but uses older, narrower slabs: nil up to ₹2.5 lakh, then 5 per cent up to ₹5 lakh, 20 per cent up to ₹10 lakh and 30 per cent above. Section 87A rebate is limited to total income up to ₹5 lakh. The trade-off is access to 80C, 80D, 24(b), HRA, LTA, professional tax and a long list of other exemptions and deductions.
What You Lose in the New Regime
- Section 80C (PPF, ELSS, life insurance, etc.) up to ₹1.5 lakh
- Section 80D (health insurance premium) up to ₹25,000 + ₹50,000
- Section 80CCD(1B) additional NPS ₹50,000
- HRA, LTA, professional tax and most allowances
- Section 24(b) home loan interest on self-occupied property (₹2 lakh)
- Most Chapter VI-A deductions except 80CCD(2) employer NPS
Quick Decision Framework
If your total Chapter VI-A deductions plus HRA and 24(b) interest exceed roughly ₹4 to ₹4.5 lakh, the old regime often wins. If you have minimal investments and rely largely on standard deduction, the new regime is typically better. Salaried taxpayers below ₹12.75 lakh gross salary almost always find the new regime superior because the 87A rebate plus standard deduction makes tax zero with no investment effort.
- Heavy investor with high 80C, 80D, NPS, home loan: old regime often wins
- Modest deductions, no home loan: new regime usually wins
- Gross salary under ₹12.75 lakh, low deductions: new regime — zero tax
- High HRA in metro plus 80C plus home loan interest: model both carefully
Surcharge Differences Between Regimes
The new tax regime caps surcharge at 25 per cent for income above ₹2 crore, compared to 37 per cent in the old regime. This makes the new regime materially more attractive for very high-income taxpayers, even if old-regime deductions are substantial. For incomes between ₹50 lakh and ₹2 crore, surcharge of 10 to 15 per cent applies in both regimes, but the relative break-even point still shifts depending on actual deductions claimed.
Practical Decision Tools
The income-tax portal's tax calculator lets you input income, deductions, exemptions and HRA to compare regimes side by side. For most salaried taxpayers, the decision should be made at the start of the financial year so that TDS deduction by the employer aligns with the final regime choice. Switching at the filing stage is possible but can lead to refund situations where excess TDS is recovered through the return.
When choosing a regime, also factor in non-tax considerations. The old regime's mandatory savings discipline (PPF, ELSS, life insurance) builds long-term wealth even though the new regime is simpler. Some taxpayers consciously opt for the old regime not for tax savings alone but to commit themselves to disciplined investments via the 80C basket. The regime decision is therefore a financial-planning decision, not merely a tax-optimisation calculation.
Conclusion
There is no universal answer — the regime choice depends on your investment portfolio, housing arrangement and salary structure. Run the numbers under both regimes every year, especially when a major change happens like buying a house, paying off a loan or starting NPS contributions. The regime can be switched annually for salaried taxpayers, so use that flexibility instead of locking into a one-time decision.
