New Tax Regime vs Old Tax Regime — Which Should You Choose? (Updated FY 2026-27)
Last verified: May 2026 against Budget 2026 and the Income Tax Act, 2025. For the deepest year-specific analysis, see Old vs New Tax Regime FY 2026-27 with live calculator.
The 30-second answer
For most salaried Indians earning under ₹13 lakh gross in FY 2026-27, the new regime wins automatically — the ₹12 lakh Section 87A rebate makes you zero-tax with no effort.
For high earners with substantial deductions (₹4-8 lakh of 80C + 80D + HRA + home loan interest combined), the old regime can still beat the new — but only above ₹15-18 lakh gross income.

What changed in Budget 2026
Budget 2026 (presented 1 February 2026) made no changes to the slabs for either regime. The blockbuster ₹12 L tax-free threshold introduced in Budget 2025 continues. The big procedural reform is the Income Tax Act, 2025 (effective 1 April 2026), which replaces the 1961 Act but preserves all charge sections, slabs, and rebates.
The new regime — what you get
| Income slab | Tax rate |
|---|---|
| 0 – ₹4,00,000 | Nil |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |
| ₹12,00,001 – ₹16,00,000 | 15% |
| ₹16,00,001 – ₹20,00,000 | 20% |
| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
Plus:
- Standard deduction: ₹75,000 (salaried & pensioners)
- Section 87A rebate: full tax wiped if taxable income ≤ ₹12 lakh (so for salaried, gross up to ₹12.75 L = zero tax)
- Surcharge capped at 25% (vs 37% in old regime above ₹5 Cr)
- Almost no other deductions allowed — no 80C, 80D, HRA, LTA, or home-loan interest on self-occupied
The old regime — what you get
| Slab (under 60) | Tax rate |
|---|---|
| 0 – ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
Plus all the deductions you give up under the new regime:
- Standard deduction: ₹50,000
- Section 87A rebate: ₹12,500 if taxable ≤ ₹5L
- Section 80C: ₹1.5 L (PPF, ELSS, EPF, life insurance, home-loan principal, etc.) — see our 80C ranking
- Section 80CCD(1B): additional ₹50K NPS
- Section 80D: ₹25K-1L health insurance — full guide
- HRA exemption (city + rent + basic salary formula)
- Section 24(b): ₹2 L home loan interest on self-occupied
- LTA, 80E, 80G, and many more
The breakeven — when does old regime start winning?
| Gross salary (FY 2026-27) | New regime tax | Deductions you’d need under old to break even |
|---|---|---|
| ₹10 L | ₹0 (rebate) | Old can never beat — new wins by ₹65,000+ |
| ₹12.75 L | ₹0 (rebate) | Old can never beat — new wins by ₹1.25 L+ |
| ₹15 L | ₹97,500 | ~₹5 L of deductions |
| ₹20 L | ₹1,92,400 | ~₹7 L of deductions |
| ₹30 L | ₹4,75,800 | ~₹8 L of deductions (deductions cap out around here) |
Translation: if you can’t honestly claim ₹4+ lakh in real deductions, new regime wins regardless of income. If you can claim ₹6+ lakh (maxed 80C, full HRA, 80D, home loan interest), old regime starts pulling ahead at ₹17-18 L gross.
How to decide in 4 steps
- Open last year’s Form 16 and add up what you actually claimed. This is your honest deduction ceiling.
- Use our FY 2026-27 calculator. Plug in your gross + the deductions from step 1.
- Pick the lower-tax regime. If they’re within ₹5,000, pick new (less paperwork).
- Inform your employer in April so TDS withholding matches your chosen regime.
Common mistakes
- Counting fictional deductions. If you don’t have rent receipts you don’t have HRA.
- Switching mid-year for one big deduction. Salaried can switch every year via the ITR but mid-year needs April planning.
- Forgetting the rebate doesn’t apply to capital gains. The ₹12 L rebate doesn’t cover LTCG above ₹1.25 L.
- Locking in old regime for business income. Business filers must file Form 10-IEA and can switch back to new only once.
- Ignoring surcharge cap. Above ₹5 Cr income, old regime hits 37% while new caps at 25%.
FAQs
Is the new regime mandatory?
No. New regime is the default but old is opt-in. Salaried can switch yearly via ITR.
Can senior citizens (60+) use the new regime?
Yes, identical slabs and rebate. But seniors with low income (under ₹6 L) often still benefit more from the old regime’s higher basic exemption (₹3 L for 60-79, ₹5 L for 80+).
What if my employer deducted TDS based on old regime but I want to switch to new?
You can switch when filing your ITR. Excess TDS will be refunded.
Does the new regime really give zero tax up to ₹12.75 lakh?
For salaried, yes — gross ₹12.75 L → ₹75K standard deduction → ₹12 L taxable → ₹60K slab tax → ₹60K rebate → zero. For non-salaried, the rebate applies up to ₹12 L taxable income.
What about employer NPS contribution under 80CCD(2)?
Allowed in both regimes. New regime allows up to 14% of salary; old allows 10%.
