Old vs New Tax Regime in 2026: Which One Actually Saves You More Tax?
Choosing between the old and new tax regimes used to be relatively straightforward. If you claimed HRA, invested ₹1.5 lakh under Section 80C, paid Old or new tax regime for AY 2026-27? Compare latest tax slabs, ₹12.75 lakh zero-tax salary, HRA, 80C, home loan and real examples. premiums and had a home loan, the old regime was often worth considering.
That calculation has changed significantly.
For income earned during FY 2025-26 (AY 2026-27), the new tax regime comes with wider slabs and a substantially higher rebate under Section 87A. An eligible resident individual with total income of up to ₹12 lakh can have no tax payable under the new regime, provided the income qualifies for the rebate.
For salaried taxpayers, the ₹75,000 standard deduction can effectively take the zero-tax salary level to ₹12.75 lakh, assuming the income is normal slab-rate income and the other conditions are satisfied.
That raises an obvious question:
Does the old tax regime still make sense in 2026?
For many salaried taxpayers, the new regime is now difficult to beat. But the old regime is far from irrelevant—particularly for people with substantial HRA exemption, home-loan interest and other genuine deductions.
The right answer depends less on your salary alone and more on what your taxable income looks like under each regime.
First, a Date Clarification
This article deals with income earned between 1 April 2025 and 31 March 2026, for which taxpayers are filing returns in AY 2026-27.
Although the Income-tax Act, 2025 came into force from 1 April 2026, the Income Tax Department has clarified that returns for AY 2026-27 continue to relate to the period governed by the Income-tax Act, 1961.
That distinction matters because taxpayers filing their FY 2025-26 returns in 2026 may otherwise assume that the new Act automatically governs those returns.
New Tax Regime Slabs for AY 2026-27
The new-regime slabs applicable for FY 2025-26 are:
| Total income | Tax rate |
|---|---|
| Up to ₹4 lakh | Nil |
| ₹4 lakh to ₹8 lakh | 5% |
| ₹8 lakh to ₹12 lakh | 10% |
| ₹12 lakh to ₹16 lakh | 15% |
| ₹16 lakh to ₹20 lakh | 20% |
| ₹20 lakh to ₹24 lakh | 25% |
| Above ₹24 lakh | 30% |
These slabs are substantially more favourable than the old-regime structure for taxpayers who do not have large deductions.
But the biggest difference for middle-income taxpayers comes from Section 87A.
For AY 2026-27, an eligible resident individual under the new regime can get a rebate of up to ₹60,000 where total income does not exceed ₹12 lakh.
This is what makes the ₹12 lakh figure so important.
How Can ₹12.75 Lakh Salary Result in Nil Tax?
Consider a salaried employee earning ₹12.75 lakh, with no other income complicating the calculation.
Gross salary: ₹12,75,000
Less standard deduction: ₹75,000
Total income: ₹12,00,000
Tax before rebate:
5% on ₹4 lakh between ₹4 lakh and ₹8 lakh = ₹20,000
10% on ₹4 lakh between ₹8 lakh and ₹12 lakh = ₹40,000
Total tax = ₹60,000
Section 87A rebate = ₹60,000
Tax payable = Nil
The Government itself has highlighted that salaried taxpayers can have nil tax at salary income up to ₹12.75 lakh because of the ₹75,000 standard deduction.
But there is an important catch.
The zero-tax headline does not mean every kind of income up to ₹12 lakh becomes tax-free. Special-rate income, such as certain capital gains, needs separate treatment.
If you have significant income from shares, mutual funds or other sources taxed at special rates, do not automatically assume that the ₹12 lakh rebate will wipe out the entire tax bill.
Why Would Anyone Still Choose the Old Regime?
Because the old regime allows a much wider range of exemptions and deductions.
Depending on the taxpayer's circumstances, these can include:
- HRA exemption under Section 10(13A)
- Section 80C deductions
- Section 80D health-insurance deduction
- eligible NPS deductions
- eligible home-loan interest
- other Chapter VI-A deductions and exemptions
The new regime generally does not allow common deductions such as Section 80C and Section 80D or HRA exemption, although certain specified deductions remain available.
For example, eligible employer contributions to NPS under Section 80CCD(2) continue to be deductible under the new regime.
So the real question isn't:
Which regime has lower tax rates?
It is:
How much tax will I actually pay after applying everything I am legally entitled to claim under each regime?
Example 1: Salary of ₹15 Lakh
Suppose a salaried taxpayer below 60 earns ₹15 lakh during FY 2025-26 and has only normal slab-rate income.
Under the new regime:
Gross salary: ₹15,00,000
Less standard deduction: ₹75,000
Taxable income: ₹14,25,000
Tax calculation:
₹4 lakh to ₹8 lakh at 5% = ₹20,000
₹8 lakh to ₹12 lakh at 10% = ₹40,000
₹12 lakh to ₹14.25 lakh at 15% = ₹33,750
Income tax = ₹93,750
Health and education cess at 4% = ₹3,750
Total tax = ₹97,500
Now compare this with the old regime.
If the taxpayer has no substantial deductions apart from the ₹50,000 standard deduction, the old regime produces a significantly higher liability.
In this simplified example, the taxpayer would need approximately ₹5.44 lakh of additional old-regime deductions and exemptions, over and above the ₹50,000 standard deduction, for the old-regime tax to fall to roughly ₹97,500.
That is a high hurdle.
Someone whose only major deduction is ₹1.5 lakh under Section 80C is therefore unlikely to make the old regime competitive at this salary level.
But someone with a sizeable HRA exemption, Section 80C investments, health-insurance deduction and other legitimate claims could get much closer.
Example 2: Salary of ₹20 Lakh
Now take an employee earning ₹20 lakh.
Under the new regime:
Gross salary = ₹20,00,000
Less standard deduction = ₹75,000
Taxable income = ₹19,25,000
Tax:
₹4 lakh to ₹8 lakh at 5% = ₹20,000
₹8 lakh to ₹12 lakh at 10% = ₹40,000
₹12 lakh to ₹16 lakh at 15% = ₹60,000
₹16 lakh to ₹19.25 lakh at 20% = ₹65,000
Income tax = ₹1,85,000
Cess at 4% = ₹7,400
Total tax = ₹1,92,400
In this simplified case, the taxpayer would need approximately ₹7.08 lakh of additional deductions and exemptions under the old regime, beyond the ₹50,000 standard deduction, for the old-regime liability to broadly match the new regime.
That sounds like a lot—and for many people it is.
But consider someone who already has a substantial HRA exemption, uses the full Section 80C limit, pays eligible health-insurance premiums and has allowable home-loan interest.
For such a taxpayer, the old regime should still be calculated rather than dismissed automatically.
How Much Deduction Does the Old Regime Need to Compete?
The following table gives a useful illustration.
It assumes a salaried individual below 60, normal slab-rate income, no surcharge and no complications such as capital gains. The figures are approximate and should not be treated as universal break-even points.
| Gross salary | New-regime tax* | Approx. additional old-regime deductions/exemptions needed to match it** |
|---|---|---|
| ₹10 lakh | Nil | ₹4.50 lakh |
| ₹12.75 lakh | Nil | ₹7.25 lakh |
| ₹15 lakh | ₹97,500 | ₹5.44 lakh |
| ₹20 lakh | ₹1,92,400 | ₹7.08 lakh |
| ₹25 lakh | ₹3,19,800 | ₹8.00 lakh |
* Includes 4% health and education cess and assumes the ₹75,000 standard deduction under the new regime.
** These figures represent deductions/exemptions required in addition to the ₹50,000 old-regime standard deduction. Actual break-even points can differ because of HRA, house-property income or loss, special-rate income, age, salary structure and other factors.
The table makes one thing clear:
There is no universal salary level at which the old regime suddenly becomes better than the new regime.
Your deductions matter.
At ₹12.75 Lakh Salary, the New Regime Is Particularly Difficult to Beat
Consider someone earning ₹12.75 lakh entirely as normal salary income.
Under the new regime, the ₹75,000 standard deduction can bring total income down to ₹12 lakh, allowing an eligible taxpayer to use the Section 87A rebate and potentially pay no tax.
What would be required to achieve nil tax under the old regime?
Starting salary: ₹12.75 lakh
Less old-regime standard deduction: ₹50,000
Balance: ₹12.25 lakh
For a non-senior individual to bring taxable income down to ₹5 lakh—the level at which the old-regime Section 87A rebate can eliminate the slab tax—another ₹7.25 lakh of legitimate deductions and exemptions would be required.
Most salaried taxpayers will find that difficult.
This is one of the clearest examples of how dramatically the latest slabs have changed the old-vs-new calculation.
HRA Can Still Make a Big Difference
HRA is one reason the old regime remains relevant.
A taxpayer might think:
“I only have ₹1.5 lakh under Section 80C, so the old regime cannot work for me.”
But that ignores HRA.
For an employee paying substantial rent and satisfying the applicable conditions, HRA exemption can materially reduce taxable income under the old regime.
The same exemption is not available under the new regime.
Consider two employees earning exactly ₹20 lakh.
One owns a house outright, has no housing loan and claims relatively few deductions.
The other pays substantial rent, receives HRA as part of salary, uses the full Section 80C limit and pays eligible health-insurance premiums.
Their salaries are identical.
Their optimal tax regimes may not be.
This is why copying the regime chosen by a colleague with the same CTC is not a sensible tax strategy.
What About Home-Loan Interest?
A housing loan can strengthen the case for the old regime.
Subject to the prescribed conditions, interest on borrowed capital for an eligible self-occupied house property can be deductible under Section 24(b) up to the applicable limit under the old regime.
For a taxpayer who already has a housing loan, this benefit can be significant when combined with other deductions.
But taking a home loan merely to save income tax rarely makes financial sense.
Paying ₹1 of interest to save a fraction of ₹1 in tax does not make you richer.
Tax benefits should improve the economics of a financial decision—not become the reason for making the decision.
Section 80C Alone Is No Longer a Strong Reason to Choose the Old Regime
For years, Section 80C was the starting point of tax planning.
The deduction can cover eligible payments and investments such as EPF, PPF, life-insurance premiums, ELSS, specified tuition fees and housing-loan principal, subject to the applicable conditions and overall limit.
But a ₹1.5 lakh Section 80C deduction alone often isn't enough to overcome the advantages of the latest new-regime slabs.
The more useful calculation is:
HRA + 80C + 80D + eligible housing-loan benefit + other genuine deductions and exemptions
versus
the lower rates and ₹75,000 standard deduction available under the new regime.
Then compare the final tax.
Don't Forget Employer NPS Contribution
The new regime does not mean “no deductions whatsoever”.
One important exception is an eligible employer contribution to the National Pension System under Section 80CCD(2).
Under the new regime, the applicable deduction can extend up to 14% of basic salary plus dearness allowance, subject to the statutory conditions.
For employees whose compensation structure includes an employer NPS contribution, this can further improve the new regime's attractiveness.
The ₹12 Lakh Zero-Tax Headline Has an Important Limitation
This is particularly relevant for investors.
The Government's own explanation of the ₹12 lakh relief expressly distinguishes special-rate income such as capital gains.
So suppose your total income consists of salary plus gains from shares or mutual funds.
Do not simply look at the final total and say:
“It is below ₹12 lakh, therefore my tax is zero.”
The tax treatment of special-rate income has to be considered separately.
This is particularly important for taxpayers with short-term or long-term capital gains.
The safest approach is to calculate the actual tax liability using the applicable ITR and current provisions rather than relying on the headline ₹12 lakh figure.
What About Income Just Above ₹12 Lakh?
There is another protection worth knowing about: marginal relief.
Without marginal relief, a person whose qualifying total income moves just above ₹12 lakh could face a disproportionate increase in tax simply because the Section 87A rebate is no longer fully available.
Marginal-relief provisions are intended to prevent the additional tax from exceeding the amount by which income crosses the specified threshold, subject to the applicable statutory conditions.
Taxpayers whose income is only slightly above ₹12 lakh should therefore not assume that the entire rebate disappears with an immediate large tax jump.
Old or New Regime: The Simplest Way to Decide
Don't choose a regime based on social-media advice or on what a colleague selected.
Calculate both.
For the new regime, start with your income and apply the ₹75,000 standard deduction for eligible salary/pension income, along with any other deductions specifically permitted under that regime.
For the old regime, calculate your genuine eligible benefits, which may include:
HRA exemption
₹50,000 standard deduction
Section 80C
Section 80D
eligible housing-loan interest
eligible NPS deductions
other applicable exemptions and deductions
Then compare the final tax payable, including cess.
That number matters more than either the tax rate or the amount of deductions considered in isolation.
Can Salaried Employees Change the Regime While Filing ITR?
For taxpayers without income from business or profession, the new regime is the default regime, but the choice between old and new can generally be made each year through the return, subject to the prescribed requirements.
There is another useful distinction.
The regime you intimate to your employer for TDS purposes does not, by itself, constitute the final exercise of the option for income-tax-return purposes.
Therefore, a salaried employee who had TDS deducted by the employer using one regime may still arrive at a different final regime when filing the return, subject to the applicable rules.
Taxpayers with business or professional income face more restrictive switching rules. Form 10-IEA and the relevant statutory conditions become important for them.
They should not apply the simpler salaried-employee rule to their own situation.
Who Is More Likely to Benefit From the New Regime?
The new regime deserves particularly strong consideration if you:
- have little or no HRA exemption;
- don't have substantial home-loan tax benefits;
- have relatively small deductions;
- don't want to make investments purely for tax saving;
- are around the ₹12.75 lakh salary level with normal slab-rate income; or
- receive an eligible employer NPS contribution.
For many such taxpayers, the new regime offers both simplicity and a lower tax bill.
When Should You Still Examine the Old Regime?
The old regime deserves a proper calculation if you:
- receive a substantial HRA exemption;
- have significant eligible home-loan interest;
- already exhaust Section 80C through genuine investments or expenses;
- pay eligible health-insurance premiums;
- qualify for additional NPS or other deductions; or
- have several exemptions and deductions arising naturally from your finances.
The phrase “arising naturally” is important.
You should not spend ₹1 lakh on an unnecessary product simply to save ₹20,000 or ₹30,000 in tax.
That isn't tax saving. It is overspending.
A Common Mistake When Comparing the Two Regimes
Don't compare gross salary under one regime with taxable income under the other.
Suppose someone earns ₹15 lakh and says:
“Under the old regime I can reduce my income to ₹10 lakh, so it must be better.”
That conclusion ignores the different slab rates and the higher standard deduction available under the new regime.
Likewise, a ₹5 lakh deduction does not mean you have saved ₹5 lakh of tax.
A deduction reduces taxable income. The actual tax saving is only the tax attributable to that reduction.
Always compare:
Final tax under the old regime
versus
Final tax under the new regime.
Frequently Asked Questions
Is income up to ₹12 lakh tax-free under the new regime for AY 2026-27?
An eligible resident individual can get a Section 87A rebate of up to ₹60,000 where total income does not exceed ₹12 lakh under the new regime. However, special-rate income such as certain capital gains requires separate treatment.
Why is ₹12.75 lakh described as a zero-tax salary?
The ₹75,000 standard deduction can reduce ₹12.75 lakh of eligible salary income to ₹12 lakh. An eligible resident taxpayer may then receive the Section 87A rebate, resulting in nil tax, assuming there is no special-rate income or other complication affecting the calculation.
Is the standard deduction the same under both regimes?
No. For the period discussed in this article, the standard deduction for eligible salary/pension income is ₹75,000 under the new regime and ₹50,000 under the old regime.
Can I claim Section 80C under the new regime?
Generally, no. Common Chapter VI-A deductions such as Section 80C and Section 80D are not available under the new regime. Certain specified deductions, including eligible employer NPS contribution under Section 80CCD(2), remain available.
Can I claim HRA exemption under the new regime?
No. HRA exemption under Section 10(13A) is available under the old regime, subject to the applicable conditions, but not under the new regime.
Does having a home loan automatically make the old regime better?
No. A home loan can provide significant tax benefits under the old regime, but whether those benefits are enough to outweigh the new regime's lower rates depends on your actual numbers.
Is the new regime always better at ₹15 lakh salary?
No. Under the simplified example used in this article, the new regime is difficult to beat without substantial deductions and exemptions. A taxpayer with significant HRA and other legitimate benefits can have a different result.
Which regime is the default?
The new tax regime is the default regime. Eligible taxpayers can opt for the old regime subject to the applicable procedural requirements.
The Bottom Line
The latest tax slabs have changed the old-versus-new-regime calculation decisively.
For salaried taxpayers with few deductions, the new regime is now likely to be the stronger starting point. Its wider slabs, ₹75,000 standard deduction and enhanced Section 87A rebate make it particularly attractive around the middle-income range.
The old regime, however, is not obsolete.
It can still work well for taxpayers who legitimately claim substantial HRA exemption, housing-loan interest, Section 80C, health-insurance deductions and other eligible benefits.
So don't ask:
“Which tax regime is better?”
Ask:
“Which regime produces the lower final tax on my actual income and deductions?”
Run that calculation every year. Your answer can change when your salary, rent, home loan, investments or family circumstances change.
