| Income Tax Slabs 2026-27 Explained: New Regime vs Old Regime in Simple Language |
First: What Even Is a Tax Regime?
Think of a tax regime as a set of rules the government gives you for calculating your tax.
India currently has two sets of rules:
The New Tax Regime — lower tax rates, but you give up most deductions and exemptions. Simple, straightforward, no paperwork.
The Old Tax Regime — slightly higher tax rates, but you can claim dozens of deductions — for investments, rent, health insurance, home loans, and more — which bring your taxable income down significantly.
The government introduced the new regime to simplify taxes for people who don't invest much. The old regime still exists for people who do invest and want to reduce their tax burden through those investments.
You pick one every year when you file your ITR. The new tax regime is the default option. However, taxpayers can still opt for the old regime if it results in lower tax liability. CoinLaw
Most people don't realise they have a choice — and end up paying more tax than they should.
The New Tax Regime: Slabs for FY 2025-26 (AY 2026-27)
The new income tax slabs and rates under the new regime for FY 2025-26 (AY 2026-27) are as follows: ₹0 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%, and income above ₹24 lakh — 30%. cbinsights
In plain language:
- Earn up to ₹4 lakh — pay zero tax
- Earn ₹6 lakh — pay 5% only on ₹2 lakh (the amount between ₹4L and ₹6L)
- Earn ₹10 lakh — pay 5% on ₹4L slab and 10% on ₹2L slab
- Earn above ₹24 lakh — the top portion gets taxed at 30%
Tax is never calculated on your full income at one rate. It's calculated slab by slab, in layers. This is the most misunderstood thing about Indian income tax.

The Big Benefit: Zero Tax Up to ₹12 Lakh
This is the headline change from Budget 2025 that continues into AY 2026-27.
Under the new tax regime, income up to ₹12 lakh is effectively tax-free due to the tax rebate under Section 87A. Additionally, salaried individuals receive a standard deduction of ₹75,000. DemandSage
What this means in practice: salaried individuals with income up to ₹12.75 lakh pay zero income tax under the new regime — the ₹75,000 standard deduction plus the ₹12 lakh rebate effectively eliminates their tax liability entirely. Arthnova
This is genuinely significant. A salaried person earning ₹12 lakh per year — ₹1 lakh per month — pays absolutely zero income tax in 2026. That's a meaningful relief for the middle class.
Important caveat: the rebate under Section 87A does not apply to special rate income such as capital gains. If you have stock market profits, those are taxed separately even if your salary is below ₹12 lakh. CoinLaw
The Old Tax Regime: Slabs for FY 2025-26 (AY 2026-27)

| The Old Tax Regime: Slabs for FY 2025-26 (AY 2026-27) |
The old regime has different slab rates — and importantly, it hasn't changed in several years.
For individuals below 60 years:
- ₹0 to ₹2.5 lakh — Nil
- ₹2.5 lakh to ₹5 lakh — 5%
- ₹5 lakh to ₹10 lakh — 20%
- Above ₹10 lakh — 30%
The old tax regime offers a higher basic exemption limit of ₹3 lakh for senior citizens aged 60-80 years, and ₹5 lakh for super senior citizens above 80 years. Dailyhunt
Under the old regime, income up to ₹5 lakh is tax-free due to the Section 87A rebate, and a standard deduction of ₹50,000 is allowed for salaried individuals. Dailyhunt
On the surface, the old regime looks worse — lower zero-tax threshold, higher rates on middle slabs. But here's where it gets interesting.
The Old Regime's Secret Weapon: Deductions
The old regime allows you to reduce your taxable income before applying the slabs. This is where it can beat the new regime for the right person.
The old tax regime allows various deductions and exemptions such as Section 80C investments up to ₹1.5 lakh, Section 80D health insurance premiums, HRA exemption, LTA, home loan interest under Section 24, and NPS contributions under Section 80CCD(1B). Oxigen Wallet
Here's what those deductions look like in practice:
| Deduction | What It Covers | Maximum Amount |
|---|---|---|
| Section 80C | PPF, ELSS, LIC, EPF, home loan principal | ₹1.5 lakh |
| Section 80D | Health insurance premium | ₹25,000 (₹50,000 for senior citizens) |
| HRA | House Rent Allowance if you pay rent | Depends on salary and city |
| Section 24(b) | Home loan interest | ₹2 lakh |
| Section 80CCD(1B) | NPS additional contribution | ₹50,000 |
| Standard Deduction | Salaried individuals | ₹50,000 |
If you claim all of these — which many salaried Indians with a home loan, health insurance, and basic investments do — your taxable income can drop by ₹4-6 lakh or more before you even apply the tax slabs.
Real Numbers: New Regime vs Old Regime
Let's make this concrete with actual examples.
Example 1: Rohan, 28, earns ₹8 lakh, no investments, no rent
New Regime:
- Standard deduction: ₹75,000
- Taxable income: ₹7.25 lakh
- Tax: 5% on ₹3.25 lakh = ₹16,250
- Below ₹12 lakh rebate threshold — Tax = ₹0
Old Regime:
- Standard deduction: ₹50,000
- Taxable income: ₹7.5 lakh
- Tax: 5% on ₹2.5 lakh + 20% on ₹2.5 lakh = ₹12,500 + ₹50,000 = ₹62,500
- Section 87A rebate applies (income below ₹5 lakh after deductions? No — ₹7.5 lakh, so no rebate)
- Tax = ₹62,500 + 4% cess = ₹65,000
Verdict: New regime saves Rohan ₹65,000.
Example 2: Priya, 34, earns ₹15 lakh, pays rent, has home loan, invests in 80C
Her deductions under old regime:
- Standard deduction: ₹50,000
- 80C investments: ₹1.5 lakh
- HRA: ₹1.2 lakh
- Home loan interest: ₹2 lakh
- 80D health insurance: ₹25,000
- Total deductions: ₹5.45 lakh
- Taxable income: ₹15L - ₹5.45L = ₹9.55 lakh
Old regime tax on ₹9.55 lakh:
- 5% on ₹2.5 lakh = ₹12,500
- 20% on ₹4.55 lakh = ₹91,000
- Total: ₹1,03,500 + 4% cess = ₹1,07,640
New regime tax on ₹15 lakh (minus ₹75,000 standard deduction = ₹14.25 lakh):
- 5% on ₹4L = ₹20,000
- 10% on ₹4L = ₹40,000
- 15% on ₹2.25L = ₹33,750
- Total: ₹93,750 + 4% cess = ₹97,500
Verdict: New regime still saves Priya ₹10,140 — but the gap is narrow. With slightly higher deductions, old regime would win.
For taxpayers with high deductions like HRA, 80C, home loan interest, and NPS contributions, the old regime may prove more beneficial. Without these deductions, the new regime is almost always more attractive. HDFC Life
The Simple Rule for Choosing Your Regime
Here it is in one sentence: if your total deductions exceed ₹3.75 lakh, compare both regimes carefully. Below that, the new regime almost always wins.
More specifically:
Choose the New Regime if:
- Your income is below ₹12.75 lakh (you pay zero tax anyway)
- You don't pay rent or have a home loan
- You don't invest much in 80C instruments
- You want simplicity — no paperwork, no investment proofs
- You are a young professional just starting out
Choose the Old Regime if:
- You pay significant rent and claim HRA
- You have a home loan with substantial interest payments
- You max out 80C investments every year
- You pay health insurance premiums for yourself and parents
- Your total deductions exceed ₹4-5 lakh
What's New in Budget 2026: Any Changes?
The Union Budget 2026 did not announce any changes to income tax slab rates under either regime. The existing slab structure continues for FY 2026-27. CoinLaw
The new tax regime remains the default option for FY 2026-27 as well, with no modifications to slabs, rebates, or standard deduction amounts announced in Budget 2026. Angel One
In short: the rules you're filing under for AY 2026-27 are the same rules that applied last year. No surprises, no new slabs, no regime changes to navigate.

The 4% Cess Everyone Forgets
After calculating your tax under either regime, add 4% Health and Education Cess on the total tax amount. This applies to everyone regardless of income level or regime chosen.
So if your calculated tax is ₹50,000, your actual payment is ₹50,000 + ₹2,000 cess = ₹52,000.
Always factor this in when comparing regimes.
Surcharge: Only for High Earners
If your income exceeds ₹50 lakh, surcharge applies on top of your tax and cess.
Under the new tax regime, the maximum surcharge is capped at 25% even for very high incomes. Under the old tax regime, the maximum surcharge can go up to 37% for incomes above ₹5 crore. Legal Raasta
For high earners above ₹2 crore, this makes the new regime significantly more attractive purely on surcharge grounds — independent of the deduction calculation.
How to Switch Regimes
If you're salaried, your employer asks you to declare your preferred regime at the start of the financial year for TDS purposes. But your final choice is made when you actually file your ITR.
Salaried individuals can switch between the new and old tax regime every year at the time of filing ITR. Business owners and self-employed individuals have more restricted switching options and should consult a CA. Meetanshi
This means even if your employer deducted TDS under the new regime all year, you can switch to the old regime at filing time if it results in lower tax — and claim a refund for the difference.
Quick Comparison Summary
| Feature | New Regime | Old Regime |
|---|---|---|
| Basic exemption | ₹4 lakh | ₹2.5 lakh |
| Zero tax up to | ₹12.75 lakh (salaried) | ₹5 lakh |
| Standard deduction | ₹75,000 | ₹50,000 |
| 80C deduction | ❌ Not allowed | ✅ Up to ₹1.5 lakh |
| HRA exemption | ❌ Not allowed | ✅ Allowed |
| Home loan interest | ❌ Not allowed | ✅ Up to ₹2 lakh |
| Health insurance 80D | ❌ Not allowed | ✅ Up to ₹25,000 |
| Default regime | ✅ Yes | ❌ Must opt in |
| Best for | Low deductions, young earners | High deductions, home loan, HRA |
The Bottom Line
The government wants you to use the new regime. That's why it's the default, why it offers zero tax up to ₹12.75 lakh, and why Budget 2026 made no changes that would make the old regime more attractive.
For most salaried Indians earning below ₹15 lakh with limited investments, the new regime genuinely wins. The math is clear.
But if you're paying rent, servicing a home loan, and maxing your 80C every year — don't default to the new regime without running the numbers first. The old regime was built for people exactly like you.
