Every year, crores of Indian salaried employees face the same question during investment declarations: "New Tax Regime or Old?" Get it wrong and you pay thousands in unnecessary tax. This guide gives you the exact decision framework — verified slabs, worked examples, and the specific conditions under which each regime wins.
New Tax Regime — FY 2026-27 Slabs
The New Tax Regime is now the default regime. If you don't explicitly opt for the Old Regime, you are automatically in the New Regime.
| Income Slab | Tax Rate |
|---|---|
| Up to ₹4 lakh | NIL |
| ₹4L – ₹8L | 5% |
| ₹8L – ₹12L | 10% |
| ₹12L – ₹16L | 15% |
| ₹16L – ₹20L | 20% |
| ₹20L – ₹24L | 25% |
| Above ₹24L | 30% |
Key new-regime benefits:
- Standard deduction: ₹75,000 for salaried and pensioners
- Section 87A Rebate of ₹60,000 — zero tax for income up to ₹12 lakh
- For salaried: effectively zero tax up to ₹12.75 lakh (₹12L + ₹75K standard deduction)
- Employer NPS contribution (up to 14% of basic) deductible under 80CCD(2) — even in new regime
- No investment declarations, no proof submission to employer
What you give up: No deductions under 80C (₹1.5L), 80D (health insurance), HRA, home loan interest (Section 24B), LTA, or any other exemption or deduction.
Old Tax Regime — FY 2026-27 Slabs
| Income Slab | Tax Rate |
|---|---|
| Up to ₹2.5 lakh | NIL |
| ₹2.5L – ₹5L | 5% |
| ₹5L – ₹10L | 20% |
| Above ₹10L | 30% |
Senior citizens (60+): ₹3L basic exemption. Super senior (80+): ₹5L. New Regime applies identically regardless of age — age gives no advantage in the new regime.
Key old-regime deductions: 80C up to ₹1.5L (PF, PPF, ELSS, LIC), 80D up to ₹25K–₹50K (health insurance), HRA, Section 24B up to ₹2L (home loan interest), 80CCD(1B) ₹50K (NPS top-up), standard deduction ₹75K, LTA.
Which Regime Saves You More? The Decision Framework
The answer comes down to: can your actual deductions cross the breakeven threshold? Below is the approximate deduction amount at which Old Regime starts saving more than New Regime.
| Gross Salary | New Regime Tax* | Deductions needed for Old to win | Verdict |
|---|---|---|---|
| ₹8L | ₹0 (rebate) | Old regime cannot win | New Regime always wins |
| ₹12L | ₹0 (rebate) | Old regime cannot win | New Regime always wins |
| ₹15L | ~₹1.05L | ~₹3.75L deductions needed | New wins if deductions below ₹3.75L |
| ₹20L | ~₹2.35L | ~₹5L deductions needed | Home loan essential for Old to win |
| ₹25L | ~₹3.65L | ~₹6L deductions needed | Old wins only with heavy deductions |
*After ₹75K standard deduction. Approximate figures; consult a CA for exact computation. 4% health & education cess applicable on all figures.
Worked Examples — Who Should Choose What?
Case 1: Rahul — ₹10L salary, rented home, no home loan
Rahul has ₹1.5L in 80C (EPF + LIC) and ₹25K in 80D. No home loan. Small HRA.
New Regime: ₹10L – ₹75K = ₹9.25L taxable → 87A rebate applies (income under ₹12L) → ₹0 tax.
Old Regime: ₹10L – ₹75K – ₹1.75L deductions = ₹7.5L taxable → ~₹62,500 tax.
Winner: New Regime by a wide margin.
Case 2: Priya — ₹18L salary, home loan + full deductions
Priya claims: 80C ₹1.5L + home loan interest ₹2L + 80D ₹50K + NPS 80CCD(1B) ₹50K + HRA ₹80K = ₹5.3L total deductions.
New Regime: ₹18L – ₹75K = ₹17.25L taxable → ~₹1.65L tax.
Old Regime: ₹18L – ₹75K – ₹5.3L = ₹11.95L taxable → ~₹1.59L tax.
Winner: Old Regime saves ~₹6,000. Heavy deductions tip the balance.
Case 3: Deepak — ₹25L salary, home loan, but no HRA (own home)
Deepak claims: 80C ₹1.5L + home loan interest ₹2L + 80D ₹50K + NPS ₹50K = ₹4.5L (no HRA).
New Regime: ~₹3.65L tax. Old Regime: ~₹3.78L tax.
Winner: New Regime saves ~₹13,000 — even with a home loan, because without HRA, deductions fall short of the ₹6L breakeven at this salary.
The Golden Rule
Old Regime wins only when all three of these are true:
- Active home loan (Section 24B: up to ₹2L interest deduction)
- Maximized 80C (₹1.5L) + 80D (₹25K–₹50K) + ideally NPS (₹50K)
- Gross salary above ₹15L
Without a home loan, Old Regime almost never wins — regardless of how diligently you invest in 80C. The home loan deduction is often the single factor that crosses the breakeven.
How to Switch Regimes
Salaried employees: Submit your choice to your employer at the start of the financial year (April–May, during investment declaration). You can also switch when filing your ITR — employer TDS choice and ITR filing choice can differ, with the ITR choice being final.
Freelancers / Business income: Opting out of New Regime requires Form 10-IEA and is largely irreversible. Once you switch to Old Regime as a business filer, switching back has significant restrictions. Decide carefully.
Tip: Salaried employees can re-decide every single year — there is no lock-in. After any major life event (salary hike, new home loan, change in rent), re-run the comparison.
Common Mistakes to Avoid
1. Choosing Old Regime by habit: Before Budget 2025 (which raised the rebate to ₹12L), the old regime made sense for more people. In FY 2026-27 specifically, anyone earning under ₹12.75L as a salaried employee pays zero tax under New Regime — there is no reason to be in Old Regime at these income levels.
2. Missing employer NPS deduction in New Regime: Section 80CCD(2) — employer's NPS contribution up to 14% of basic — is deductible even in the New Regime. This is a genuinely valuable deduction that many employees overlook.
3. Not reviewing every year: A salary hike, new home loan, or change in rent can shift the balance. Review every April before submitting investment declarations.
Conclusion: Run Your Own Numbers
There is no universal answer. For salaried employees earning under ₹12.75L — New Regime wins automatically (zero tax). For ₹15L+ with home loan and full deductions exceeding ₹3.75L — run both calculations; Old Regime may win.

Old Tax Regime — FY 2026-27 Slabs
| आय सीमा | कर दर |
|---|---|

| ₹2.5L – ₹5L | 5% |
| ₹5L – ₹10L | 20% |

कौन सी Regime बेहतर? Decision Framework
| Gross Salary | New Regime Tax* | Old जीतने के लिए deductions | Result |
|---|---|---|---|
| ₹8L–₹12L | ₹0 (rebate) | नहीं जीत सकती | New Regime always wins |
| ₹15L | ~₹1.05L | ~₹3.75L चाहिए | Home loan न हो तो New |
| ₹20L | ~₹2.35L | ~₹5L चाहिए | Home loan ज़रूरी |
Worked Examples
Case 1: Rahul — ₹10L salary, home loan नहीं
New Regime: ₹10L – ₹75K = ₹9.25L → 87A rebate → ₹0 tax।
Old Regime: ~₹62,500 tax।
Winner: New Regime — कोई मुकाबला नहीं।
Case 2: Priya — ₹18L salary, home loan + full deductions
Priya के पास: 80C ₹1.5L + home loan ₹2L + 80D ₹50K + NPS ₹50K + HRA ₹80K = ₹5.3L total।
New Regime: ~₹1.65L। Old Regime: ~₹1.59L।
Winner: Old Regime — ₹6,000 बचत।
Golden Rule
Old Regime तब जीतती है जब तीनों हों:
- Active home loan (₹2L interest deduction)
- पूरी 80C (₹1.5L) + 80D + NPS
- Gross salary ₹15L से ऊपर
Home loan न हो तो New Regime लगभग हमेशा जीतती है।
Regime Switch कैसे करें?
Salaried: हर साल switch कर सकते हैं। Employer को April में बताएं या ITR file करते समय July 31 से पहले।
Business income: Old Regime में जाना largely irreversible — Form 10-IEA required। सोच-समझकर decide करें।
आम गलतियाँ
पुरानी आदत से Old Regime: Budget 2025 ने rebate ₹12L तक बढ़ाई। ₹12.75L से कम कमाने वाले salaried के लिए New Regime में zero tax — Old Regime का कोई कारण नहीं।
Employer NPS भूलना: 80CCD(2) — employer NPS — New Regime में भी deductible। बहुत लोग यह miss करते हैं।
हर साल review न करना: Salary hike, नया home loan — हर April check करें।
निष्कर्ष
₹12.75L से कम — New Regime zero tax। ₹15L+ पर home loan और ₹3.75L+ deductions हों तो Old Regime check करें। BachatKaGyan के Income Tax Calculator से 2 मिनट में exact comparison करें।
