Every salaried Indian now faces the same annual question: pick the new tax regime, with its lower slab rates but almost no deductions, or stick with the old tax regime, with higher rates but a long list of exemptions and deductions if you actually use them. Since the new regime became the default in FY 2023–24, and the Budget 2025 slab revision made it even more attractive, most taxpayers now save more under it - but not everyone. This article walks through the real numbers so you can pick with confidence, not guesswork.
The real question: which regime saves you more?
The new-vs-old debate is really a single question dressed up in tax jargon: do your eligible deductions outweigh what the old regime's higher rates cost you? If yes, the old regime wins. If your deductions are small - or you simply don't have a home loan, big rent, or an insurance-heavy portfolio - the new regime almost always comes out ahead.
This wasn't always a close call. Before Budget 2025, the new regime's slabs were only modestly better than the old ones, and many taxpayers with home loans or HRA still came out ahead in the old regime. That has changed. With the ₹12 lakh rebate threshold and wider slabs introduced in Budget 2025, the new regime now offers zero tax up to ₹12.75 lakh of salary (after the ₹75,000 standard deduction) - a bar that is genuinely hard for the old regime to beat unless your deductions are substantial.
Since FY 2023–24, the new tax regime is the default option. If you don't actively opt for the old regime while filing your return (or submitting investment declarations to your employer), you are automatically taxed under the new regime. Salaried employees can switch between regimes every year; those with business income face restrictions on how often they can switch back.
Neither regime is a trap - both are legitimate, and the government designed the new regime specifically to simplify filing for people who don't use deductions heavily. The right answer depends entirely on your own numbers, not on which one is “newer” or which one your colleague picked.
How the new tax regime works
The new regime trades away almost every deduction and exemption in return for lower, wider slab rates. You get a flat ₹75,000 standard deduction (for salaried individuals and pensioners) and a generous rebate under Section 87A - but that's essentially it. No HRA, no 80C, no home loan interest deduction, no LTA.
| Taxable income slab | Rate (New Regime) |
|---|---|
| ₹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% |
Under Section 87A, taxpayers with taxable income up to ₹12,00,000 pay zero tax in the new regime - this is a rebate, not a slab change, so it only applies below the threshold; cross it by even ₹1 and tax is computed on the full slab structure (with marginal relief easing the jump). Add the ₹75,000 standard deduction and a salaried employee effectively pays no tax up to a ₹12.75 lakh salary.
The only deduction still available in the new regime is Section 80CCD(2) - your employer's contribution to your NPS account (up to 14% of basic salary for private-sector employees, 14% for government employees), since this is treated as a business expense for the employer, not a personal tax break. Everything else - 80C, 80D, HRA, home loan interest - is off the table.
How the old tax regime works
The old regime has higher rates and narrower slabs, but it rewards taxpayers who invest, insure, pay rent, or service a home loan. Its entire design philosophy is behavioural - it nudges you toward long-term savings (PPF, ELSS, EPF), insurance, and homeownership by taxing you less if you do those things.
| Taxable income slab | Rate (Old Regime) |
|---|---|
| ₹0 – ₹2,50,000 | Nil |
| ₹2,50,001 – ₹5,00,000 | 5% |
| ₹5,00,001 – ₹10,00,000 | 20% |
| Above ₹10,00,000 | 30% |
The old regime also gives a Section 87A rebate, but at a much lower threshold: taxable income up to ₹5,00,000 pays zero tax. Above that, the 20% and 30% slabs kick in far earlier than in the new regime - which is exactly why deductions matter so much here. Every rupee of 80C, HRA, or home loan interest you claim reduces income that would otherwise be taxed at 20% or 30%.
A salaried employee in a metro city, paying rent, servicing a home loan, and maxing out 80C and NPS, can realistically claim ₹4.5–5 lakh in combined deductions. On a ₹15–20 lakh salary, that can flip the comparison back in the old regime's favour, despite its steeper slab rates.
Slab-by-slab rate comparison
Placed side by side, the new regime's advantage is obvious at lower incomes and narrows - sometimes reverses - as income and deductions rise. The old regime taxes anything above ₹10 lakh at a flat 30%, while the new regime spreads that same income across 15%, 20%, and 25% slabs before finally reaching 30% only above ₹24 lakh.
- →New regime: nil slab up to ₹4L vs old regime's ₹2.5L
- →New regime: 30% only kicks in above ₹24L vs old regime's ₹10L
- →New regime: 87A rebate up to ₹12L vs old regime's ₹5L
- →New regime: ₹75,000 standard deduction vs old regime's ₹50,000
- →Old regime: full menu of 80C, 80D, HRA, and 24(b) available
Real numbers: salary-wise tax across both regimes
Numbers settle this debate faster than slab charts. Below is the tax payable at common salary levels, assuming a moderately engaged old-regime taxpayer who claims the standard deduction plus a realistic (not maximum) combination of 80C, 24(b), and HRA where applicable.
| Gross salary | Assumed old-regime deductions | Tax: Old Regime | Tax: New Regime |
|---|---|---|---|
| ₹6,00,000 | ₹75,000 std. deduction | Nil | Nil |
| ₹8,00,000 | ₹1,00,000 std. deduction | Nil | Nil |
| ₹10,00,000 | ₹2,00,000 (80C + std. ded.) | ₹20,000 (post-rebate: Nil below ₹12L) | ₹33,800 |
| ₹12,00,000 | ₹2,50,000 (80C + 24b + std.) | Nil (rebate up to ₹12L) | ₹83,200 |
| ₹15,00,000 | ₹3,25,000 (80C + 24b + HRA + std.) | ₹97,500 | ₹1,66,400 |
| ₹20,00,000 | ₹4,00,000 (80C + 24b + HRA + std.) | ₹2,45,000 | ₹3,53,600 |
| ₹30,00,000 | ₹4,25,000 (80C + 24b + HRA + std.) | ₹5,20,000 | ₹6,86,400 |
At ₹10 lakh and ₹12 lakh, the new regime wins clearly - the ₹12 lakh rebate makes tax nil regardless of what you could have claimed in the old regime. At ₹15 lakh and above, the old regime starts to catch up if deductions are meaningful, and by ₹30 lakh with strong 80C, 24(b), and HRA usage, the old regime can pull ahead by well over ₹1.5 lakh a year.
Deductions & exemptions you lose in the new regime
This is the single most important table for anyone deciding between the two regimes. Every row below is a deduction you simply cannot claim if you opt for the new regime - no matter how much you actually spend or invest.
| Deduction / exemption | New Regime | Old Regime |
|---|---|---|
| Standard deduction | ₹75,000 | ₹50,000 |
| Section 80C (PPF, ELSS, life insurance, EPF) | Not allowed | Up to ₹1,50,000 |
| Section 24(b) - home loan interest (self-occupied) | Not allowed | Up to ₹2,00,000 |
| HRA exemption | Not allowed | Up to 50% of basic (metro) |
| Section 80D - health insurance premium | Not allowed | Up to ₹25,000–₹1,00,000 |
| Section 80CCD(1B) - NPS additional | Not allowed | Up to ₹50,000 |
| Section 80TTA/80TTB - savings/FD interest | Not allowed | Up to ₹10,000–₹50,000 |
| LTA (Leave Travel Allowance) | Not allowed | Exempt (twice in 4 yrs) |
| Section 80CCD(2) - employer NPS contribution | Allowed | Allowed |
Home loan interest under Section 24(b) - up to ₹2 lakh a year for a self-occupied property - is often the single largest deduction old-regime taxpayers rely on. Switching to the new regime while still repaying a home loan means giving up this benefit entirely, which is why homeowners should always run both calculations before switching.
The break-even deduction amount
Rather than comparing salary bands, the fastest way to decide is to find your break-even point - the total deductions you'd need to claim in the old regime for it to match the new regime's tax outcome. Below this amount, the new regime wins. Above it, the old regime wins.
For most salary levels between ₹10 lakh and ₹20 lakh, the break-even point falls around ₹4.25 lakh to ₹4.75 lakh in total deductions (standard deduction plus 80C, 24(b), HRA, and 80D combined). If you can realistically claim more than this, run the old regime numbers. If you're below it, don't bother - the new regime wins without any effort.
This break-even figure isn't fixed - it shifts slightly with income because both regimes have different slab structures at different levels. Someone earning ₹12 lakh exactly at the new regime's rebate threshold effectively needs an infinite deduction advantage to beat “zero tax,” while someone earning ₹25 lakh has a lower relative bar to clear because they're deep into the 30% slab under the old regime.
When the new regime wins
For a large and growing share of salaried India, the new regime is simply the better and simpler choice - not a compromise. Here are the situations where it clearly wins.
- ✓You don't have a home loan or claim minimal deductions
- ✓You live with parents or don't pay rent (no HRA to claim)
- ✓Your total eligible deductions are under ~₹4–4.5 lakh
- ✓You want a simpler return with less paperwork and no proof-collection
- ✓You are early in your career with few investments or insurance policies
- ✓Your taxable income is at or below ₹12 lakh (near-zero tax after rebate)
This is especially true for younger professionals early in their careers - no home loan yet, living with family or in a company-provided flat, and not yet deep into insurance or PPF contributions. For this group, the new regime's simplicity and lower rates make it the obvious pick, often with zero tax liability up to ₹12.75 lakh of salary.
When the old regime wins
The old regime hasn't become obsolete - it remains the better choice for taxpayers with genuine, substantial deductions, especially at higher income levels where the flat 30% slab starting at ₹10 lakh is offset by a large deduction base.
- ✓You pay significant rent and claim a large HRA exemption
- ✓You have an active home loan and claim Section 24(b) interest
- ✓You max out 80C (PPF, ELSS, EPF) plus NPS under 80CCD(1B)
- ✓You pay high health insurance premiums for family and parents (80D)
- ✓Your combined eligible deductions exceed roughly ₹4.5–5 lakh
- ✓You are disciplined about tax-saving investments and want the deduction incentive
The clearest case for the old regime is a mid-career homeowner in a metro city - paying a home loan EMI, claiming HRA before possession, contributing to PPF and ELSS for 80C, and paying health insurance premiums for a spouse, children, and parents. Stacked together, these deductions frequently cross ₹5 lakh, comfortably clearing the break-even point.

Final verdict & decision framework
There is no single correct regime for everyone - the right choice depends on your salary level, your actual (not hypothetical) deductions, and whether you value simplicity over maximising every possible tax break. Use this checklist to decide quickly.
The single most reliable way to decide: don't estimate - calculate. Plug your exact salary, deductions, and exemptions into a proper income tax calculator for both regimes and compare the final numbers. A five-minute calculation beats any rule of thumb, including the ones in this article.
If your salary is under ₹12–13 lakh, or your deductions are modest, the new regime almost always wins - and it's simpler too. If you have a home loan, pay significant rent, and are disciplined about 80C and 80D investments, run the old regime numbers before assuming the new one is better. Re-check every year - your income, your loan status, and the slabs themselves can all change.
