Every year, millions of Indian taxpayers face the same question sitting at their desk in March: should I go with the old tax regime or the new one? It sounds straightforward, but the answer is genuinely different for every person — and choosing wrong can cost you tens of thousands of rupees in avoidable tax.
The new tax regime is better for taxpayers with fewer deductions and investments, while the old tax regime saves more money for those who actively claim Section 80C, HRA, home loan interest, and other exemptions. But the devil is entirely in the details — and that is exactly what this guide breaks down for you, income bracket by income bracket, deduction by deduction.
Let us settle this once and for all.
What Is the Old Tax Regime in India?
The old tax regime is the original income tax structure that has existed under the Income Tax Act 1961. It offers higher tax rates but allows taxpayers to reduce their taxable income through a wide range of deductions and exemptions.
Under the old regime, you can claim deductions for investments under Section 80C, health insurance premiums under Section 80D, House Rent Allowance under Section 10(13A), home loan interest under Section 24(b), National Pension System contributions under Section 80CCD, Leave Travel Allowance under Section 10(5), and dozens of other benefits.
The basic exemption limit under the old tax regime is ₹2.5 lakh for individuals below 60 years, ₹3 lakh for senior citizens (60–80 years), and ₹5 lakh for super senior citizens above 80 years.
The old tax regime rewards disciplined investors. If you put money into PPF, ELSS mutual funds, life insurance, NPS, or claim HRA and home loan deductions, the old regime can bring your taxable income down significantly — often making it the lower-tax option despite its higher headline rates.
What Is the New Tax Regime in India?
The new tax regime was introduced through the Finance Act 2020 and was significantly revamped in Budget 2023, when it became the default tax regime for all taxpayers. From the financial year 2023-24 onwards, if you do not actively choose the old regime, the Income Tax Department automatically applies the new regime to your return.
The new tax regime offers lower, more simplified tax slabs — but it removes most of the deductions and exemptions that the old regime provides. You cannot claim Section 80C, HRA exemption, LTA, or home loan interest deductions under the standard new regime.
However, Budget 2023 and Budget 2025 brought meaningful improvements to the new regime:
- The standard deduction of ₹75,000 is now available for salaried employees under the new regime
- The Section 87A tax rebate makes income up to ₹7 lakh completely tax-free under the new regime
- Budget 2025 further raised the rebate limit, making income up to ₹12 lakh effectively zero-tax under the new regime for most salaried individuals
- The NPS employer contribution deduction under Section 80CCD(2) is still allowed in the new regime
The new regime is designed for simplicity. It works best for younger earners who have not yet built up significant tax-saving investments, or for those whose employers do not provide HRA or other allowances.

New Tax Regime vs Old Tax Regime: Tax Slabs Comparison 2025-26
New Tax Regime Slabs (FY 2025-26)
| Income Range | Tax Rate |
|---|---|
| Up to ₹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% |
Note: Section 87A rebate applies up to ₹12 lakh income, making effective tax zero for most salaried individuals in this bracket.
Old Tax Regime Slabs (FY 2025-26)
| Income Range | 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% |
A 4% health and education cess applies to the total tax liability under both regimes. Surcharge of 10% applies above ₹50 lakh income, and 15% above ₹1 crore.
Key Deductions Available Under the Old Tax Regime
This is where the old regime earns its advantage. The old tax regime allows deductions under the following sections:
Section 80C — Up to ₹1,50,000 Covers PPF contributions, ELSS mutual fund investments, NSC, 5-year tax saving fixed deposits, life insurance premiums, home loan principal repayment, children’s tuition fees, and Sukanya Samriddhi Yojana contributions.
Section 80D — Up to ₹25,000 (₹50,000 for senior citizens) Covers health insurance premiums paid for self, spouse, and children. An additional ₹25,000 to ₹50,000 is available for parents’ health insurance. Use the free India TDS Calculator at Free Calculaters to estimate how much TDS is being deducted from your salary.
Section 10(13A) — HRA Exemption House Rent Allowance is exempt from tax based on a formula: the least of actual HRA received, 50% of basic salary (40% for non-metros), or actual rent paid minus 10% of basic salary. This can be a very significant deduction for employees in Mumbai, Delhi, Bangalore, and other metro cities.
Section 24(b) — Home Loan Interest Up to ₹2,00,000 Interest paid on a home loan for a self-occupied property is deductible up to ₹2 lakh per year. For a home loan borrower paying ₹1.8 lakh in interest annually, this is a direct reduction in taxable income.
Section 80CCD(1B) — Additional NPS Deduction ₹50,000 Over and above the ₹1.5 lakh Section 80C limit, an additional ₹50,000 can be claimed for NPS contributions — making the total possible deduction ₹2 lakh from these two sections alone.
Section 80E — Education Loan Interest Interest on an education loan for higher studies is fully deductible with no upper limit for up to 8 years.
Section 80G — Charitable Donations Donations to approved charitable institutions are deductible at 50% or 100% depending on the organisation.
Section 80TTA / 80TTB — Savings Account Interest Up to ₹10,000 of savings account interest is deductible under 80TTA for individuals below 60. Senior citizens can claim up to ₹50,000 under Section 80TTB.
LTA — Leave Travel Allowance Actual travel expenses for domestic travel twice in a 4-year block are exempt under Section 10(5).
Professional Tax Professional tax paid (up to ₹2,400 annually) is deductible from salary income.
What Deductions Are Allowed in the New Tax Regime?
The new tax regime has a much shorter list of allowed deductions:
- Standard deduction of ₹75,000 for salaried employees and pensioners
- Employer’s NPS contribution under Section 80CCD(2)
- Agniveer Corpus Fund deduction under Section 80CCH
- Family pension standard deduction of ₹25,000
That is essentially the complete list. HRA exemption is not available in the new tax regime. Section 80C is not available. Home loan interest under Section 24(b) cannot be claimed. LTA is not exempt. This is the fundamental trade-off — lower rates, but a much smaller deduction toolkit.
Old vs New Tax Regime: Real Examples by Income Bracket
For ₹7 Lakh Salary
Under the new tax regime, ₹7 lakh income attracts zero tax thanks to the Section 87A rebate (after applying the ₹75,000 standard deduction, taxable income becomes ₹6.25 lakh, and the rebate eliminates the tax entirely).
Under the old regime, the same ₹7 lakh salary with no deductions would attract approximately ₹32,500 in tax (before cess). With ₹1.5 lakh in 80C deductions, tax falls to around ₹2,500.
Winner for ₹7 lakh with minimal deductions: New regime (zero tax)
For ₹10 Lakh Salary
Under the new tax regime with ₹75,000 standard deduction: taxable income is ₹9.25 lakh. Approximate tax before cess: ₹52,500.
Under the old tax regime with ₹75,000 standard deduction + ₹1.5 lakh (80C) + ₹25,000 (80D) + ₹24,000 (HRA, conservative estimate): taxable income falls to approximately ₹7.26 lakh. Tax: approximately ₹52,520 before cess.
At ₹10 lakh, the regimes are very close. If you claim HRA significantly higher than this example, the old regime wins. Use the HRA Exemption Calculator at Free Calculaters to calculate your exact HRA deduction.
Winner for ₹10 lakh: Depends on deductions — roughly equal with standard deductions
For ₹15 Lakh Salary
Under the new tax regime with ₹75,000 standard deduction: taxable income ₹14.25 lakh. Approximate tax: ₹1,50,000 before cess.
Under the old tax regime with full deductions — ₹75,000 standard deduction + ₹1.5 lakh (80C) + ₹50,000 (80CCD 1B NPS) + ₹25,000 (80D) + ₹2 lakh (HRA) + ₹2 lakh (home loan interest Section 24b): taxable income falls to approximately ₹7 lakh. Tax: around ₹25,000 before cess.
Winner for ₹15 lakh with full deductions: Old regime — saves approximately ₹1.25 lakh or more
For ₹20 Lakh Salary
At ₹20 lakh, the gap widens further. With the same full deduction profile, a taxpayer under the old regime can bring taxable income down to ₹12 lakh or below — paying substantially less than under the new regime’s flat structure.
Winner for ₹20 lakh and above with active deductions: Old regime
The Breakeven Point — At What Deduction Level Does the Old Regime Win?
This is the most searched tax question in India, and the answer is clear: the old tax regime becomes better than the new tax regime when your total deductions exceed approximately ₹3.75 lakh for incomes around ₹15 lakh.
Here is a simple rule of thumb:
- If your total annual deductions (80C + 80D + HRA + home loan + NPS + LTA + others) are less than ₹3.5 lakh, the new regime likely saves you more money
- If your total deductions exceed ₹3.75 lakh, the old regime typically results in lower tax
- If you have a home loan with ₹2 lakh interest deduction AND full 80C of ₹1.5 lakh AND HRA, the old regime almost always wins for incomes above ₹10 lakh
The specific breakeven point varies by income level. At ₹10 lakh income, the breakeven is around ₹1.5 lakh in deductions. At ₹15 lakh, it rises to roughly ₹3.75 lakh. At ₹20 lakh and above, it moves toward ₹4.5 lakh.
Can I Switch Between Old and New Tax Regime Every Year?
Yes — but with an important condition. Salaried employees without business income can switch between old and new tax regime every financial year. You simply need to inform your employer at the start of the year for TDS purposes, and then confirm your choice when filing your ITR.
Business owners and self-employed professionals are in a different position. Once a taxpayer with business income opts out of the new tax regime and switches to the old regime, they can only switch back to the new regime once in their lifetime. This is a one-time option, so business owners need to make this decision very carefully.
If you do not actively declare a preference, the new regime is applied by default from FY 2023-24 onwards under CBDT rules.
Which Tax Regime Is Better for Senior Citizens?
Senior citizens have a higher basic exemption limit of ₹3 lakh under the old regime, and super senior citizens (above 80) enjoy a ₹5 lakh exemption. Combined with Section 80TTB (₹50,000 deduction on interest income), Section 80D (₹50,000 for their own health insurance), and pension deductions, the old regime often provides significantly better outcomes for retirees with investment income.
However, senior citizens with simple pension income and minimal deductions may still find the new regime easier to manage and occasionally more beneficial — especially if their income falls in the lower brackets where the new regime‘s lower rates apply.
Use the India Income Tax Calculator at Free Calculaters to run both scenarios quickly.
Which Tax Regime Is Better for Government Employees?
Government employees typically receive a structured salary package that includes HRA, LTA, and gratuity components, along with mandatory EPF and NPS contributions. These employees usually benefit significantly from the old regime because:
- HRA exemption is substantial in metros like Delhi, Mumbai, and Bangalore
- NPS employer contributions (80CCD2) are available in both regimes — but additional employee NPS contributions (80CCD1B, ₹50,000) are only deductible under the old regime
- Gratuity and leave encashment exemptions are available in both regimes
For Chennai government employees, Pune professionals, and Bangalore IT employees, the old regime almost always wins if they claim full 80C and HRA.
Old vs New Regime: Which Is Better for Home Loan Borrowers?
If you are repaying a home loan, the old tax regime is almost certainly better. Here is why:
- Home loan principal repayment is deductible under Section 80C (up to ₹1.5 lakh)
- Home loan interest is deductible under Section 24(b) (up to ₹2 lakh for self-occupied property)
Together, these two deductions alone account for up to ₹3.5 lakh in deductions — more than enough to tip the balance toward the old regime for most income levels. The new tax regime offers zero benefit for home loan interest, making it a poor choice for property owners with active housing loans.
Tax Saving Investments That Work Under the Old Regime
If you choose the old regime, here are the best instruments to maximise your deductions before March 31:
Under Section 80C (₹1.5 lakh limit):
- PPF (Public Provident Fund) — tax-free returns, 15-year lock-in
- ELSS Mutual Funds — 3-year lock-in, market-linked returns, most liquid option
- 5-Year Tax Saving Fixed Deposits
- NSC (National Savings Certificate)
- Sukanya Samriddhi Yojana (for daughters below 10)
- Life insurance premium payments
- Children’s tuition fees
Beyond Section 80C:
- NPS under Section 80CCD(1B) — additional ₹50,000 deduction
- Health insurance under Section 80D
- Education loan interest under Section 80E — unlimited deduction
- Donations under Section 80G

Frequently Asked Questions
What is the difference between old and new tax regime in India? The old tax regime offers higher tax rates but allows over 70 deductions and exemptions including Section 80C, HRA, home loan interest, and LTA. The new tax regime offers lower, simplified tax slabs but removes most deductions. The new regime is the default from FY 2023-24 onwards.
Which tax regime is better for a ₹10 lakh salary? At ₹10 lakh salary, the two regimes are roughly equal if you claim standard deductions only. However, if you claim HRA, full Section 80C, and health insurance deduction, the old regime saves approximately ₹10,000–₹25,000 more annually. Use the India Income Tax Calculator at Free Calculaters for an exact comparison based on your specific deductions.
Is Section 87A rebate available in both regimes? The Section 87A rebate is available in both regimes, but the limits differ. Under the new tax regime, the rebate makes income up to ₹12 lakh effectively tax-free for FY 2025-26. Under the old regime, the rebate applies to income up to ₹5 lakh, making it fully tax-free with the standard deduction.
Can salaried employees switch tax regime every year? Yes. Salaried employees without business income can switch between old and new tax regime every financial year. You inform your employer for TDS purposes and confirm your choice at the time of ITR filing. Business owners can only switch back to the new regime once after opting out.
Is HRA exemption available in the new tax regime? No. House Rent Allowance exemption under Section 10(13A) is not available in the new tax regime. Employees living in rented accommodation in cities like Mumbai, Delhi, or Bangalore lose a significant deduction by choosing the new regime. For HRA claimants, the old regime is almost always more beneficial. Calculate your exact HRA exemption using the India HRA Exemption Calculator at Free Calculaters.
What happens if I don’t choose a tax regime? If you do not actively choose a tax regime, the Income Tax Department automatically applies the new tax regime as the default for FY 2023-24 onwards, as per CBDT guidelines. To opt for the old regime, you must explicitly declare this to your employer and in your ITR filing.
Conclusion — Make the Right Choice Before March 31
India’s income tax system gives you the power to choose — but that power only works in your favour if you use it wisely. The new tax regime saves money for taxpayers with limited deductions, simple finances, and lower income brackets. The old tax regime saves significantly more for anyone with a home loan, HRA, active 80C investments, and health insurance.
The single most important step is to actually run the numbers for your specific income and deduction profile — not rely on a general rule. Every rupee you miscalculate is a rupee the government keeps that could have stayed in your pocket.
