From April 1, 2025, the New Tax Regime became India's default tax regime. If you haven't actively chosen, you're already in it. But for many salaried professionals — especially those with a home loan, HRA, NPS, and health insurance — the Old Regime still saves significantly more. This article gives you the exact numbers to decide, not guesswork.
The One-Minute Decision Matrix
New Regime Wins If: Total deductions (excl. standard deduction) are below ₹3.75 lakh, OR your income is ₹12,75,000 or less (zero tax).
Old Regime Wins If: You have a Home Loan + HRA + 80C + 80D + NPS — combined deductions exceeding ₹3.75 lakh.
Both Regimes: LTCG ₹1,25,000 annual exemption applies to both — harvest gains every year.
The Slab Rates: Side by Side
Both regimes apply to the same gross income. The difference lies in how much you can subtract before tax is calculated.
New Tax Regime — FY 2025-26 (Default)
| Income Slab | Tax Rate | Tax on This Slab |
|---|---|---|
| Up to ₹4,00,000 | NIL | ₹0 |
| ₹4,00,001 – ₹8,00,000 | 5% | Up to ₹20,000 |
| ₹8,00,001 – ₹12,00,000 | 10% | Up to ₹40,000 |
| ₹12,00,001 – ₹16,00,000 | 15% | Up to ₹60,000 |
| ₹16,00,001 – ₹20,00,000 | 20% | Up to ₹80,000 |
| ₹20,00,001 – ₹24,00,000 | 25% | Up to ₹1,00,000 |
| Above ₹24,00,000 | 30% | 30% on balance |
Key Benefit: Salaried individuals earning up to ₹12,75,000 pay zero tax in the New Regime — thanks to the ₹12,00,000 rebate under Section 87A plus the ₹75,000 standard deduction.
Old Tax Regime — FY 2025-26
| Income Slab | Tax Rate |
|---|---|
| Up to ₹2,50,000 | NIL |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
Key Benefit: Full deduction eligibility — Standard deduction ₹50,000, 80C (₹1.5L), 80D (up to ₹1L), HRA, LTA, NPS 80CCD(1B) (₹50K extra), and Home Loan Interest (₹2L under Section 24b). These reduce taxable income significantly despite higher slab rates.

The Breakeven Rule: ₹3.75 Lakhs Threshold
Across salary levels between ₹10 Lakhs and ₹20 Lakhs, the decision threshold centers around a single figure:
Do your total deductions (excluding standard deduction) exceed ₹3,75,000?
YES → Old Regime
Home Loan + HRA + 80C + 80D + NPS
NO → New Regime
Minimal deductions, no home loan
Strategy 1: LTCG Harvesting — ₹15,625 Free, Every Year (Both Regimes)
This is the most underused tax strategy in India. It works regardless of which regime you're in.
How It Works
- LTCG on equity mutual funds and listed shares held 12+ months is taxed at 12.5%
- The first ₹1,25,000 of LTCG every financial year is completely tax-free
- This exemption does NOT carry forward — if you don't use it this year, it's gone
The 4-Step Harvest Strategy (30 minutes, once a year)
Step 1: Check your equity portfolio for unrealised long-term gains (held 12+ months)
Step 2: Before March 31, sell enough units to realise exactly ₹1,25,000 in gains
Step 3: Immediately buy the same fund back the next trading day
Step 4: Your cost basis resets higher — future gains are lower, future tax is lower
| Scenario | Without Harvesting | With Harvesting |
|---|---|---|
| Gains over 5 years | ₹6,25,000 (booked in year 5) | ₹1,25,000/year × 5 years |
| Tax payable | ₹78,125 | ₹0 |
| 5-Year Saving | — | ₹78,125 saved |
Annual saving: ₹15,625. Takes 30 minutes. Works under BOTH regimes. Do this before March 31 every year.
Strategy 2: NPS 80CCD(1B) — ₹50,000 Extra Deduction Almost Nobody Uses
Most people max out 80C (₹1,50,000) with PPF, ELSS, LIC — then stop. Here's what they miss:
Section 80CCD(1B) gives you an additional ₹50,000 deduction for NPS contributions — completely separate from and above the ₹1,50,000 80C limit. This is extra. You can claim both.
Under Old Regime
| Deduction | Section | Limit | Tax Saved (30%) |
|---|---|---|---|
| PPF / ELSS / LIC / EPF | 80C | ₹1,50,000 | ₹46,800 |
| NPS (additional) | 80CCD(1B) | ₹50,000 | ₹15,600 |
| Total | ₹2,00,000 | ₹62,400 |
Under New Regime
Personal NPS contributions (80CCD(1B)) are not deductible in the New Regime. However, your employer's NPS contribution under Section 80CCD(2) — up to 14% of Basic+DA — is fully deductible even in the New Regime.
Example: Basic salary ₹8L. If your employer routes 14% to NPS = ₹1,12,000 — this entire amount is deductible even in the New Regime. Ask your HR to restructure your CTC to include employer NPS contribution.
Strategy 3: HRA + Home Loan Together — Yes, You Can Claim Both
One of the most common misconceptions: "I have a home loan so I can't claim HRA." That's wrong. You can claim both — if they relate to different properties.
When You Can Claim Both (Old Regime Only)
Real Numbers: Salaried in Delhi, Home Loan on Hometown Property
| Item | Amount |
|---|---|
| Basic Salary | ₹10,00,000 |
| Rent paid (Delhi) | ₹20,000/month = ₹2,40,000/year |
| HRA deduction (lowest of: actual rent / 50% basic / HRA received) | ₹2,40,000 |
| Home Loan Interest deduction (Sec 24b) | ₹2,00,000 |
| Total Combined Deductions | ₹4,40,000 |
| Tax Saved at 30% slab | ₹1,32,000 + 4% cess |
Your ₹50,000–80,000 Annual Saving: How the Numbers Add Up
For a salaried professional earning ₹15–25 lakh in the Old Regime with full deductions:
| Strategy | Annual Tax Saving |
|---|---|
| Choosing the correct tax regime | ₹10,000 – ₹40,000 |
| LTCG Harvesting (₹1.25L annual exemption) | ₹15,625 |
| NPS 80CCD(1B) — ₹50,000 extra deduction | ₹10,000 – ₹15,600 |
| HRA + Home Loan (if applicable) | ₹20,000 – ₹50,000 |
| Total Possible Annual Saving | ₹55,625 – ₹1,21,225 |
Conservative estimate for most salaried professionals: ₹50,000–80,000 per year. This is money you are already entitled to keep. It's just not being claimed correctly.
