Old Tax Regime vs New Tax Regime: Which One Saves You More in 2026?
Every April, your company’s Human Resources (HR) department sends a form. It asks you to pick the old vs new tax regime. Most salaried professionals either click “new” by default or copy whatever their colleague chose. Neither is the same as calculating which one actually saves them money. The answer depends almost entirely on one number: how much you genuinely claim in deductions, every year, not in theory.
This article gives you the exact breakeven number at your salary level — the total deduction amount above which the old regime saves more, and below which the new regime wins outright. No opinions. Just the calculation.
The Income-tax Act, 2025 (Act No. 30 of 2025, effective 1 April 2026) replaced the Income-tax Act, 1961 from 1 April 2026. The slab rates, standard deductions, and rebate amounts are unchanged from the previous year under both regimes. Section numbers shifted (80C is now Section 123; 80D is now Section 126; the new regime is now governed by Section 202 instead of 115BAC) — but the actual rupee limits and rates are identical to what applied in FY 2025-26.
1Old vs New Tax Regime: The Two Options Side by Side
The core difference is a trade-off: lower rates with almost no deductions in the new regime, versus higher rates with a full menu of deductions in the old regime. The new regime is the default since FY 2023-24 — if you do nothing, this is what applies.
- Standard deduction: ₹75,000
- Section 87A rebate: ₹60,000 (taxable income ≤ ₹12L)
- Employer National Pension System (NPS) contribution (80CCD(2)) allowed
- House Rent Allowance (HRA), 80C, 80D, home loan interest: not allowed
- Switch back to old regime every year (salaried)
- Standard deduction: ₹50,000
- Section 87A rebate: ₹12,500 (taxable income ≤ ₹5L)
- 80C: up to ₹1.5L (Public Provident Fund/PPF, Equity Linked Savings Scheme/ELSS, Employees’ Provident Fund/EPF, Life Insurance Corporation/LIC premiums, home loan principal)
- 80D: ₹25,000 self/family; ₹50,000 senior parents
- HRA, home loan interest (₹2L self-occupied), NPS 80CCD(1B) ₹50,000
2The Rebate Is the Entire Story Below ₹12.75 Lakh
The single biggest reason most salaried professionals under ₹12.75 lakh annual gross should be on the new regime has nothing to do with slab rates. It’s the Section 87A rebate.
Under the new regime, anyone whose taxable income (after the ₹75,000 standard deduction) falls at or below ₹12,00,000 gets a rebate of up to ₹60,000 on their computed tax. That’s enough to wipe out the entire tax liability up to that threshold. A salaried professional earning ₹12,75,000 gross annually pays zero income tax — the standard deduction brings their taxable income to exactly ₹12,00,000, and the rebate clears the remaining computed tax of ₹60,000.
The old regime’s Section 87A rebate is only ₹12,500, applicable up to ₹5,00,000 taxable income. At ₹10L gross salary with no deductions, the old regime computes ₹1,06,600 in tax. By contrast, the new regime computes zero — the rebate fully clears it. To make the old regime match that zero, you’d need deductions of ₹4,50,000 above the standard deduction. That’s more than the entire 80C limit plus NPS plus 80D combined.
This is also why your Tax Deducted at Source (TDS) might have dropped to zero this year even without any change in your salary — if your annual gross is under ₹12,75,000 and you’re on the new regime, your employer is correctly deducting nothing. In other words, it’s not an error. The rebate made your liability zero before deductions even became relevant.
3Old vs New Tax Regime Breakeven Table — Where Old Regime Starts Winning
At higher incomes, where the Section 87A rebate no longer applies, both regimes compute actual tax. The question becomes: how much do your real deductions need to total for the old regime to pull ahead?
The Breakeven Numbers, Salary by Salary
The table below shows the exact breakeven point at each salary level — computed using the actual FY 2026-27 slab rates and the ₹25,000 extra standard deduction advantage the new regime carries (₹75,000 vs ₹50,000). All numbers include the 4% cess and assume a salaried individual below 60 years of age.
| Annual Gross Salary | New Regime Tax | Old Regime Tax (no deductions) | Deductions Needed to Beat New Regime | Verdict |
|---|---|---|---|---|
| ₹8,00,000 | ₹0 | ₹65,000 | ₹2,50,000+ | New regime wins |
| ₹10,00,000 | ₹0 | ₹1,06,600 | ₹4,50,000+ | New regime wins |
| ₹12,00,000 | ₹0 | ₹1,63,800 | ₹6,50,000+ | New regime wins |
| ₹15,00,000 | ₹97,500 | ₹2,57,400 | ₹5,43,750+ | Calculate yours |
| ₹18,00,000 | ₹1,50,800 | ₹3,51,000 | ₹6,41,667+ | Calculate yours |
| ₹20,00,000 | ₹1,92,400 | ₹4,13,400 | ₹7,08,333+ | Old regime possible |
| ₹25,00,000+ | ₹3,19,800+ | ₹5,69,400+ | ~₹8,00,000 | Old regime possible |
Where the ₹15L–₹20L Band Gets Close
The ₹15L–₹20L band is where the decision genuinely needs individual calculation. At ₹15L gross, for example, you’d need total deductions of ₹5.44L to make the old regime win — that’s a realistic number if you have a home loan, full 80C, NPS contribution, and health insurance. At ₹12L gross, by contrast, you’d need ₹6.5L in deductions — functionally impossible without a large home loan on top of everything else.
Add up the most common deductions: 80C ₹1.5L + NPS 80CCD(1B) ₹50,000 + 80D health insurance ₹25,000 (self) + ₹50,000 (senior parents) + home loan interest 24(b) ₹2L + HRA (depends on rent paid) + 80TTA savings interest ₹10,000. Without HRA and home loan, you’re around ₹2.35L. With a full home loan and HRA in a metro, you can approach ₹6L–₹8L. The number that matters is your actual real-world claim — not the ceiling.
4Worked Example — ₹10 Lakh Annual Gross (New Regime Wins Clearly)
A salaried professional in Pune earning ₹10,00,000 annually (roughly ₹83,000/month gross) is on the new regime. Their employer has already applied the ₹75,000 standard deduction.
| Step | New Regime | Old Regime (no extra deductions) |
|---|---|---|
| Annual Gross Pay | ₹10,00,000 | ₹10,00,000 |
| Standard Deduction | −₹75,000 | −₹50,000 |
| Other Deductions | Nil | Nil |
| Taxable Income | ₹9,25,000 | ₹9,50,000 |
| Computed Tax (before rebate) | ₹32,500 | ₹1,02,500 |
| Section 87A Rebate | −₹32,500 | Nil |
| 4% Cess | ₹0 | ₹4,100 |
| Final Annual Tax | ||
| Tax Payable | ₹0 | ₹1,06,600 |
Even if this professional claims ₹1.5L under 80C and ₹25,000 under 80D, their old regime tax comes to ₹70,200 — still noticeably higher than the new regime’s zero. To match the new regime’s zero, they’d need ₹4,50,000 in total deductions above the standard deduction. That’s more than this income level can realistically generate.
5Worked Example — ₹15 Lakh Annual Gross (Calculate Yours)
A salaried professional in Bengaluru earning ₹15,00,000 annually is above the rebate threshold in both regimes. Here the slab rate gap between the two regimes matters more, and deductions become genuinely useful.
| Step | New Regime | Old Regime (₹4.25L deductions) |
|---|---|---|
| Annual Gross Pay | ₹15,00,000 | ₹15,00,000 |
| Standard Deduction | −₹75,000 | −₹50,000 |
| 80C + NPS + 80D deductions | Not allowed | −₹2,25,000 |
| Home loan interest (24b) | Not allowed | −₹2,00,000 |
| Taxable Income | ₹14,25,000 | ₹10,25,000 |
| Computed Tax (before cess) | ₹93,750 | ₹1,20,000 |
| 4% Cess | ₹3,750 | ₹4,800 |
| Final Annual Tax | ||
| Tax Payable | ₹97,500 | ₹1,24,800 → ₹91,000 with HRA |
At ₹4.25L in deductions, the old regime tax (₹1,24,800) is still higher than the new regime’s ₹97,500. However, add a HRA exemption of around ₹1.5L for a Bengaluru renter paying ₹25,000/month in rent, and the old regime drops to roughly ₹91,000 — now narrowly ahead, by about ₹6,500. The margin is thin at this exact deduction level, so the decision genuinely needs individual calculation — a slightly larger HRA claim or a bit more 80D can widen it meaningfully, but ₹15L with this deduction mix is close, not a clear win either way.
Many professionals ask whether they can claim both HRA (for paying rent at their current city) and home loan interest deduction (for a property elsewhere or under construction). Under the old regime: yes, both are claimable if the conditions are genuinely met — you’re actually renting the place you live in and paying an Equated Monthly Instalment (EMI) on a separate property. Under the new regime: neither is available. This combination is often what swings the decision at ₹15L+ incomes.
6What You Can and Cannot Claim in Each Regime
The deduction lists are where most confusion starts. Here’s the complete picture for FY 2026-27 under the Income-tax Act, 2025 — note that section numbers have changed from the 1961 Act, but the limits are identical.
| Deduction / Exemption | New Regime | Old Regime |
|---|---|---|
| Standard Deduction | ₹75,000 | ₹50,000 |
| 80C (PPF, ELSS, LIC, home loan principal, EPF) | Not allowed | Up to ₹1,50,000 |
| NPS — Employee contribution 80CCD(1) | Not allowed | Within 80C limit |
| NPS — Additional 80CCD(1B) | Not allowed | ₹50,000 extra |
| NPS — Employer contribution 80CCD(2) | Up to 14% of salary | Up to 10% of salary |
| Health Insurance 80D (self/family) | Not allowed | ₹25,000 |
| Health Insurance 80D (senior parents) | Not allowed | ₹50,000 extra |
| HRA Exemption | Not allowed | Depends on rent paid |
| Home Loan Interest (self-occupied) 24(b) | Not allowed | Up to ₹2,00,000 |
| Home Loan Interest (let-out property) 24(b) | Allowed (no limit) | Allowed (no limit) |
| Leave Travel Allowance (LTA) | Not allowed | Allowed (conditions) |
| Savings Interest 80TTA | Not allowed | Up to ₹10,000 |
| Family Pension Deduction | ₹25,000 | ₹15,000 |
One thing most articles miss: the employer NPS contribution under 80CCD(2) is available in both regimes, but the ceiling is higher in the new regime — 14% of salary versus 10% in the old regime. If your employer offers NPS and contributes meaningfully, this can shift the math at higher salary levels.
7Two Scenarios Where Old Regime Wins — and One Common Near-Miss
For most salaried professionals under ₹12.75L, this section is academic — the new regime wins so cleanly that deductions can’t catch up. At ₹15L and above, two real deduction combinations genuinely cross the breakeven. A third — the one most people assume settles it — usually doesn’t, on its own, and it’s worth seeing why.
Scenario A — Why a Home Loan Alone Usually Isn’t Enough
A salaried professional in Hyderabad, ₹18L gross, paying EMI on a home they live in, with no separate rented property and no HRA claim. Even maxing out every deduction available in this exact situation — home loan interest ₹2,00,000 under Section 24(b), 80C ₹1,50,000, 80D ₹75,000 (self plus senior parents), and NPS 80CCD(1B) ₹50,000, a realistic ceiling of ₹4,75,000 — the old regime tax comes to ₹2,02,800.
The new regime tax at the same salary is ₹1,50,800. It still wins, by ₹52,000, and the gap widens rather than narrows as salary rises further. In short, a self-occupied home loan by itself, without HRA or a much larger deduction stack, is rarely enough to flip the decision in this salary band — despite being the deduction most people assume settles it.
Scenario B — Home Loan Plus HRA (Renting in a Metro, Property Elsewhere)
A product manager in Mumbai, ₹20L gross, renting in the city (paying ₹30,000/month rent) while repaying a home loan on a property in their hometown. HRA exemption is claimable on the Mumbai rent (lowest of actual HRA received, 50% of Basic, or rent paid minus 10% of Basic).
Add home loan interest ₹2L, 80C ₹1.5L, NPS ₹50,000, 80D ₹25,000, and enough HRA to bring total deductions to around ₹8L, and old regime tax drops to roughly ₹1,63,800 against the new regime’s ₹1,92,400 — a real saving of about ₹28,600 a year. This is the combination — HRA stacked on top of a home loan, not a home loan alone — where the old regime wins most clearly at high incomes.
Scenario C — Senior Parents on Dependent Health Insurance
A salaried professional, ₹15L gross, paying health insurance premiums for dependent parents above 60 years of age. This alone adds ₹50,000 to their 80D claim. Combined with 80C ₹1.5L and NPS ₹50,000, they’re at ₹2.5L in deductions before HRA or home loan. Without a home loan, this still doesn’t cross the ₹5.44L breakeven at ₹15L — but it brings it meaningfully closer, and a modest home loan in a Tier 2 city can close the gap.
The new regime isn’t better or worse. It’s a bet on simplicity — that lower rates are worth more than deductions you might not fully use. The old regime is a bet that your real deductions cross the breakeven. Run the actual number before April. One of those bets is clearly wrong for you specifically.
8How to Switch — and When
Salaried professionals without business income can switch between regimes every financial year. There are two points in the year where this matters:
Declaring at the Start of the Year
At the start of the financial year (April), your employer asks for a declaration of which regime you want for TDS purposes. Whatever you declare here determines how much TDS is deducted from your salary each month throughout the year. If you declare the new regime but file under the old regime later, you may get a refund — but you’ll have overpaid TDS all year and only recovered it at filing time. Getting the declaration right upfront avoids this.
Choosing Again at ITR Filing Time
At Income Tax Return (ITR) filing time (July–December), salaried individuals can change the regime, even if a different regime was declared to the employer. The ITR filing itself is the binding election. If you declared new regime to your employer but want to file under old regime, you can — the difference in TDS will come back as a refund, or you’ll pay the shortfall as self-assessment tax.
If any part of your income is from business or profession (including freelancing, consulting, or tuition income), the switching rules are more restrictive. Once you opt out of the new regime, you need to file Form 10-IEA before the ITR due date to revert to the old regime, and you can only switch back to the new regime once. If your income is purely from salary, ignore this — the simpler rules above apply.

The Bottom Line
If your salary is under ₹12.75 lakh and you’re on the new regime, you likely owe zero income tax right now and the old regime would cost you money. Above ₹15 lakh, on the other hand, a genuine home loan, HRA claim, and senior parent health insurance together can flip that — run both numbers, because the old regime might then save you ₹20,000–₹60,000 a year. Below that combination of deductions at that salary level, the new regime’s lower rates win every time. The right answer isn’t ideological. It’s arithmetic.
❓ अक्सर पूछे जाने वाले प्रश्न
The new regime is almost always better at ₹10 lakh annual gross. Under the new regime, the ₹75,000 standard deduction plus the ₹60,000 Section 87A rebate wipes out the entire tax liability — you pay zero. Under the old regime with no deductions, you’d pay ₹1,06,600. To make the old regime match that zero, you’d need deductions of ₹4,50,000 — more than this income level can realistically generate through 80C, 80D, and NPS alone.
It depends on your real deductions. At ₹15 lakh annual gross, you’d need deductions totalling ₹5,43,750 to make the old regime match the new regime’s tax. If you have a home loan (₹2L interest), HRA exemption, full 80C (₹1.5L), NPS (₹50,000), and senior parent health insurance (₹50,000), you can reach and exceed this threshold — making the old regime genuinely better. Without a home loan and HRA together, you’ll likely stay better off in the new regime.
Yes, if you’re a salaried individual without business income. You can switch regimes every financial year — either by declaring your choice to your employer at the start of the year (for TDS purposes) or by selecting the regime when filing your ITR. If you have business or professional income, the rules are more restrictive and you’ll need to file Form 10-IEA to exit the new regime, with limited switching allowed thereafter.
The new regime allows very few deductions: standard deduction of ₹75,000 for salaried individuals, employer NPS contribution under Section 80CCD(2) up to 14% of salary, family pension deduction of ₹25,000, and home loan interest on a let-out property (no limit, under Section 24). HRA, 80C investments, 80D health insurance, home loan interest on self-occupied property, LTA, and most other Chapter VI-A deductions are not available.
Yes. The new regime is the default under Section 202 of the Income-tax Act, 2025 (which replaced Section 115BAC of the old Act from 1 April 2026). If you haven’t explicitly told your employer you want the old regime, you’re being taxed under the new regime. Salaried individuals can opt for the old regime by declaring it to their employer at the start of the year or by selecting it at the time of filing their ITR.
No. Under the Income-tax Act, 2025, 80C is now renumbered as Section 123, but it remains available only under the old tax regime — the same restriction that applied under Section 80C of the old Act. The deduction limit stays at ₹1,50,000. Taxpayers on the new regime cannot claim PPF, ELSS, LIC premiums, home loan principal, or EPF contributions as deductions under either the old or the new Act’s numbering.
Under the new regime, the Section 87A rebate is ₹60,000, available when taxable income (after the standard deduction) is at or below ₹12,00,000. This rebate wipes out the entire computed tax for anyone below that threshold. For salaried individuals, the standard deduction of ₹75,000 means gross salary up to ₹12,75,000 carries zero tax liability. In the old regime, the rebate is only ₹12,500, applicable up to ₹5,00,000 taxable income.
Yes, if the conditions genuinely apply — you’re paying rent at the city where you work and repaying a home loan on a different property (often in your hometown or for an under-construction flat). Both HRA exemption and home loan interest deduction under Section 24(b) can be claimed simultaneously under the old regime in this scenario. This combination often makes the old regime the better choice at ₹15L+ incomes. Neither deduction is available in the new regime.
