The Break-Even Point
The key question: How many deductions do you need to claim before the Old Regime beats the New Regime?
Here's the rule of thumb for FY 2026-27:
| Annual Income | Break-Even Deduction Needed | Likely Better Regime |
|---|---|---|
| Up to ₹7,75,000 | — | Both: ₹0 tax (rebate) |
| ₹10,00,000 | ~₹2.5 lakh | New (unless big deductions) |
| ₹12,75,000 | — | New: ₹0 tax (rebate) |
| ₹15,00,000 | ~₹4.0 lakh | New (mostly) |
| ₹20,00,000 | ~₹4.5 lakh | Old (if large home loan + HRA) |
| ₹30,00,000 | ~₹4.5 lakh | Old (if available) |
| ₹50,00,000+ | ~₹4.75 lakh | Old (typically achievable) |
Real Examples by Income Level
Example 1: ₹10,00,000 Salary, No Major Deductions
(Common case for early-career professionals, single, no home loan)
New Regime:
- Taxable income = 10,00,000 − 75,000 = ₹9,25,000
- Tax = 5% × 4L + 10% × 1.25L = 20,000 + 12,500 = ₹32,500
- Section 87A: Income < ₹12L → rebate of ₹32,500 → Tax = ₹0
Old Regime (assuming ₹1.5L 80C only):
- Taxable income = 10,00,000 − 50,000 − 1,50,000 = ₹8,00,000
- Tax = 5% × 2.5L + 20% × 3L = 12,500 + 60,000 = ₹72,500
- Plus 4% cess = ₹2,900
- Total tax = ₹75,400
Winner: New Regime saves ₹75,400
Example 2: ₹15,00,000 Salary, Moderate Deductions
(Mid-career professional, claiming ₹1.5L 80C + ₹50K 80CCD(1B) + ₹25K 80D + ₹1.5L HRA = ₹3.75L total)
New Regime:
- Taxable = 15,00,000 − 75,000 = ₹14,25,000
- Tax = 0 + 5%×4L + 10%×4L + 15%×2.25L = 20,000 + 40,000 + 33,750 = ₹93,750
- Plus 4% cess = ₹3,750
- Total = ₹97,500
Old Regime:
- Taxable = 15,00,000 − 50,000 − 3,75,000 = ₹10,75,000
- Tax = 12,500 + 1,00,000 + 22,500 = ₹1,35,000
- Plus 4% cess = ₹5,400
- Total = ₹1,40,400
Winner: New Regime saves ₹42,900
Example 3: ₹20,00,000 Salary, Heavy Deductions
(Married, home loan + HRA + maxed 80C: ₹2L home loan + ₹1.5L 80C + ₹50K 80CCD(1B) + ₹50K 80D + ₹2L HRA = ₹6.5L total)
New Regime:
- Taxable = 20,00,000 − 75,000 = ₹19,25,000
- Tax = 20,000 + 40,000 + 60,000 + 65,000 = ₹1,85,000
- Plus 4% cess = ₹7,400
- Total = ₹1,92,400
Old Regime:
- Taxable = 20,00,000 − 50,000 − 6,50,000 = ₹13,00,000
- Tax = 12,500 + 1,00,000 + 90,000 = ₹2,02,500
- Plus 4% cess = ₹8,100
- Total = ₹2,10,600
Winner: New Regime still saves ₹18,200
Example 4: ₹30,00,000 Salary, Maxed Deductions
(Senior professional, ₹2L home loan + ₹1.5L 80C + ₹50K 80CCD(1B) + ₹75K 80D + ₹3L HRA = ₹7.75L)
New Regime:
- Taxable = 30,00,000 − 75,000 = ₹29,25,000
- Tax = 20,000 + 40,000 + 60,000 + 80,000 + 1,00,000 + 1,57,500 = ₹4,57,500
- + 4% cess = ₹18,300
- Total = ₹4,75,800
Old Regime:
- Taxable = 30,00,000 − 50,000 − 7,75,000 = ₹21,75,000
- Tax = 12,500 + 1,00,000 + 3,52,500 = ₹4,65,000
- + 4% cess = ₹18,600
- Total = ₹4,83,600
Winner: New Regime saves ₹7,800 (very close — depends on exact deductions)
Special Note for Govt Employees
Central government employees have a unique situation that often makes the Old Regime more attractive:
Why Old Regime Often Wins for Govt Staff
- Higher 80CCD(2) employer contribution: 14% of (Basic+DA) for govt vs 10% for private — both regimes allow this, so no edge
- HRA in metros (X-class): 30% of basic = significant exemption when paying actual rent
- NPS contributions are mandatory: 10% employee contribution gets 80CCD(1) deduction in old regime — this is forced anyway, so why not benefit?
- Education allowances: CEA, Hostel allowance — small but adds up
For a Level 8+ central govt employee in Delhi/Mumbai paying actual rent of ₹15,000+/month, the Old Regime usually wins by ₹15,000–₹40,000/year.
For govt employees in Z-class cities (low HRA, modest rent), New Regime almost always wins.
Can You Switch Regimes Every Year?
Yes, salaried individuals can switch between regimes every year when filing their ITR — you simply select the regime in your tax return.
However, there's a critical caveat for self-employed/business income taxpayers:
- Salaried only: Switch regimes every year freely
- Business/Profession income: Once you opt out of New Regime, you can return to it only ONCE in your lifetime
So if you're salaried and your situation changes (took a home loan, got married, parents now need health insurance), recompute every year and pick the better regime.
Filing Form 10-IEA
If you have business/professional income and want to opt for Old Regime, you must file Form 10-IEA before the due date for filing your ITR. Salaried-only employees don't need this form — just choose the regime in your ITR.
Frequently Asked Questions
I'm earning ₹12,75,000. Do I really pay zero tax in the New Regime?
Yes, for salaried employees. Standard deduction of ₹75,000 brings taxable income to ₹12,00,000. Section 87A rebate of ₹60,000 fully offsets the tax. Final liability: ₹0. This is the "sweet spot" of the new regime.
What if my salary is ₹13 lakh — just above the rebate threshold?
You'll pay tax on the full taxable income (₹12.25L after standard deduction), which works out to roughly ₹65,000. So crossing ₹12.75L by even a rupee costs you a chunk in tax. There's a marginal relief provision, but it's limited.
Can I claim home loan interest in the New Regime?
Only for let-out (rented) property. For self-occupied property, the ₹2 lakh interest deduction under Section 24(b) is NOT available in the new regime. This is the biggest reason home loan borrowers stick with the old regime.
Does the surcharge apply differently in the two regimes?
Yes. Surcharge is capped at 25% in New Regime for income above ₹2 crore. Old Regime allows up to 37% surcharge for income above ₹5 crore. This makes New Regime significantly better for ultra-high earners.
What about Section 80CCD(2) — employer NPS contribution?
This is available in BOTH regimes. For govt employees, employer's NPS contribution of 14% of (Basic+DA) is fully deductible. This is a major reason govt employees can have effective deductions of ₹2L+ even in the New Regime.
I've already chosen New Regime in my Form 16. Can I switch when filing ITR?
Yes. Your employer's TDS may have been calculated assuming New Regime, but when you file your ITR, you can choose Old Regime if it saves you more. You'll either get a refund (if TDS exceeds final liability) or pay the difference.
