Income Tax New Tax Regime vs Old Tax Regime: Which Is Better?
The new tax regime offers lower slab rates and fewer deductions. The old regime permits many exemptions and deductions but uses higher rates. The better option depends on taxable income, eligible deductions, residential status and the nature of income.
What are the old and new tax regimes?
New tax regime: The default tax computation framework for eligible individuals, Hindu undivided families and certain other taxpayers, with concessional slab rates but restrictions on specified deductions and exemptions. It was governed by Section 115BAC of the Income-tax Act, 1961 for relevant earlier years and is provided under Section 202 of the Income-tax Act, 2025 for Tax Year 2026-27 onwards.
Old tax regime: The alternative system under which eligible taxpayers can claim permitted deductions and exemptions, such as eligible investments, medical insurance premiums, house rent allowance and certain housing-loan benefits, subject to conditions.
Total income: Income computed under the applicable statutory provisions after permissible exemptions, set-offs and deductions. Slab rates generally apply to taxable total income, not simply gross salary. Special-rate income may be taxed separately.

| Up to 2,50,000 | Nil | Nil | Nil |

These are marginal slab rates, not flat rates on the whole income. Age-based basic exemption limits under the old regime depend on residential status. A 4% Health and Education Cess generally applies to the computed tax, plus surcharge where relevant.
Deductions and exemptions: important differences
| Tax benefit | Old regime | New regime |
|---|---|---|
| Section 80C investments (PPF, ELSS, eligible LIC, etc.) | Generally up to Rs. 1,50,000, subject to conditions | Generally unavailable |
| Section 80D medical insurance | Eligible deduction subject to limits | Generally unavailable |
| House rent allowance exemption | Available if conditions are met | Generally unavailable |
| Leave travel concession exemption | Available if conditions are met | Generally unavailable |
| Interest on self-occupied house property | Eligible deduction subject to limits | Generally unavailable |
| Employer contribution to qualifying pension scheme | Available subject to statutory limits | Available subject to statutory limits |
| Standard deduction from salary | Rs. 50,000 | Rs. 75,000 |
Deduction availability depends on the precise provision and the taxpayer's facts. References to familiar 1961 Act deduction numbers are included for ease of understanding; the 2025 Act reorganizes statutory numbering.
Section 87A rebate: can income up to Rs. 12 lakh be tax-free?
Under the new regime, an eligible resident individual with qualifying total income up to Rs. 12,00,000 can receive a rebate of up to Rs. 60,000 against normal slab tax. Income taxed at special rates does not receive this rebate in the same way. Marginal relief may apply when qualifying total income slightly exceeds Rs. 12 lakh.
For eligible salaried taxpayers, the Rs. 75,000 standard deduction can mean that gross salary of up to Rs. 12,75,000 results in qualifying total income of Rs. 12 lakh, assuming no other taxable income or adjustments. This is not a universal tax-free threshold for all forms of income.
Under the old regime, eligible resident individuals with qualifying total income up to Rs. 5,00,000 may claim a rebate of up to Rs. 12,500, subject to the law.
Illustrative tax calculations
Examples below assume a resident individual below 60, only normal-rate income, no surcharge, and 4% cess. Old-regime deductions stated are assumed eligible. They are illustrations, not individual tax advice.
| Scenario | New regime tax incl. cess | Old regime tax incl. cess | Lower tax |
|---|---|---|---|
| Gross salary Rs. 12,00,000; no additional deductions | Rs. 0 (salary less Rs. 75,000; rebate) | Rs. 1,63,800 (salary less Rs. 50,000) | New |
| Gross salary Rs. 15,00,000; eligible old-regime deductions Rs. 4,00,000 in addition to standard deduction | Rs. 97,500 | Rs. 1,06,600 | New |
| Gross salary Rs. 15,00,000; eligible old-regime deductions Rs. 5,00,000 in addition to standard deduction | Rs. 97,500 | Rs. 85,800 | Old |
Calculation check: On Rs. 15 lakh salary, new-regime taxable salary is Rs. 14.25 lakh. Slab tax is Rs. 93,750 and cess Rs. 3,750, totaling Rs. 97,500. Under the old regime with Rs. 5 lakh additional eligible deductions, taxable salary is Rs. 9.5 lakh; slab tax is Rs. 82,500 and cess Rs. 3,300, totaling Rs. 85,800.
Which tax regime is better for you?
The new regime is often preferable for taxpayers who do not claim substantial exemptions and deductions, especially those eligible for the Rs. 12 lakh rebate. It can also be simpler because fewer claims need to be substantiated.
The old regime can be preferable where significant deductions or exemptions are legally available, including HRA, housing-loan interest, eligible savings and medical insurance. The amount required for the old regime to win changes with income, age and other facts; there is no universal break-even deduction.
How do you select or switch tax regimes?
The new regime is the default for eligible taxpayers. Taxpayers without business or professional income can generally choose the old regime in their timely filed return, subject to applicable filing rules. Taxpayers with business or professional income face additional conditions and restrictions on switching; the applicable election form and due date should be verified for the relevant tax year. For AY 2026-27 under the 1961 Act, Form 10-IEA is relevant to eligible business taxpayers opting out of the default regime.
An employee's declaration to an employer for TDS calculation does not by itself determine the final regime election in the income-tax return.
Frequently asked questions
Is the new tax regime compulsory?
No. It is the default for eligible taxpayers, but the old regime may be selected subject to the applicable election rules.
Is Rs. 12 lakh always tax-free?
No. The new-regime rebate is subject to residence, total-income and special-rate-income conditions. It is not an across-the-board exemption for every taxpayer.
Can I claim Section 80C in the new regime?
Ordinary Section 80C investment deductions are generally not available in the new regime.
Which regime is better for a home-loan borrower?
The old regime may be more beneficial if eligible housing-loan deductions and other claims are substantial. Calculate both outcomes before choosing.
Does the Income-tax Act, 2025 change the regime comparison?
For Tax Year 2026-27, Section 202 carries forward the new-regime slab structure. The old and new systems must still be compared using the provisions applicable to that tax year.
