Old vs New Tax Regime FY 2026-27: The Complete Break-Even Guide
Find your exact break-even deduction number to choose between Old and New Tax Regime for FY 2026-27. Compare slabs, rebates, and take-home pay.
The dilemma every salaried Indian faces in 2026
Every financial year, your company HR asks you to declare your tax regime.
On one side is the Old Tax Regime: higher slab rates, but packed with deductions for house rent (HRA), home loan interest (§24b), life insurance, EPF, and medical premiums (§80D).
On the other side is the New Tax Regime: significantly lower tax slabs, a flat ₹75,000 standard deduction, and zero income tax for gross salaries up to ₹12.75 Lakhs thanks to the Section 87A rebate.
The question is simple: Exactly how much money must you spend on deductions to make the Old Regime beat the New Regime? Here is the exact break-even math.
1. The break-even deduction table across salary tiers
If your total deductions (80C + 80D + HRA + Home Loan Interest) are higher than the break-even number, pick Old Regime. If they are lower, pick New Regime.

How to Use Break-Even Analysis to Choose Your Tax Regime
1. The ₹12.75 Lakh Zero-Tax Threshold
Under FY 2026-27 New Tax Regime, any salary up to ₹12.75 Lakhs (₹12L income + ₹75k standard deduction) pays ₹0 income tax thanks to the enhanced Section 87A rebate.
2. The Investment Lock-In Trap
In the Old Regime, to save ₹40,000 in tax, you often have to lock away ₹1.5 Lakhs in PPF/ELSS for 3 to 15 years. The New Regime gives you the same tax savings with 100% liquid cash in hand.

Regime breakeven, with your numbers
The new regime has lower rates but almost no deductions. The old regime only wins once your deductions are large enough to offset that rate gap. Below the breakeven figure the new regime costs less; above it the old regime does. Compare it against deductions you genuinely claim, not ones you might.

When the New Tax Regime is Better
- Salaries up to ₹12.75 Lakhs: You pay ₹0 tax automatically without locking any cash into lock-in schemes.
- Young professionals renting cheap: If you live with parents or pay modest rent, you cannot claim enough HRA to beat the ₹4L+ break-even threshold.
- No home loan: Without ₹2 Lakhs of home loan interest deduction under Section 24(b), reaching ₹4.25L deductions is very difficult.
- Zero paperwork: No need to submit rent receipts, landlord PAN, or insurance premium proofs to HR every January.
When the Old Tax Regime Still Wins
- Paying high metro rent: If you claim ₹2.5L+ in HRA exemptions plus ₹1.5L under 80C, your total deductions cross ₹4L easily.
- Active home loan borrowers: Claiming ₹2 Lakhs under Section 24(b) plus ₹1.5L under 80C plus ₹50k under 80D puts your deductions at ₹4.5L+, making Old Regime save you ₹30,000 to ₹60,000 extra.
5-Step Checklist to Pick Your Regime in 5 Minutes
1. Check if Gross CTC is under ₹12.75 Lakhs
If your gross salary is ₹12.75L or less, choose New Tax Regime immediately. Your tax liability is exactly ₹0.
2. Add up your real guaranteed deductions
Calculate your actual Section 80C (EPF + ELSS), Section 80D (Mediclaim), and Section 24(b) Home Loan Interest.
3. Calculate your eligible HRA exemption
Check how much HRA you can legitimately claim based on rent receipts and metro city rules.
4. Compare total deductions against your breakeven threshold
At ₹15L the threshold is about ₹5.44 Lakhs, at ₹20L about ₹7.09 Lakhs, and from ₹30L upward ₹8 Lakhs. Clear it and the Old Regime saves tax; below it the New Regime wins.
5. Inform HR or declare during July ITR filing
Salaried employees can switch regimes when filing their actual ITR in July, even if they declared differently to HR.
