Income tax slabs are ranges of income set by the Act, each taxed at a different rate. India follows a progressive taxation system, wherein the tax rate increases with a rise in income. While the tax slabs under the old regime offer many deductions, the new tax regime offers relaxed tax slabs with limited deductions.
Income Tax Slabs are income ranges determined by the Income Tax Act, taxed under different rates. Individuals can choose between the old and the new tax regime, and the option can be exercised at the time of filing ITR.
Under the new regime, the basic exemption limit is ₹4 lakh, with the highest tax rate of 30%. Under the old regime, the basic exemption limit is ₹2.5 lakhs, with a maximum tax rate of 30%. Slabs under the old regime are relaxed to ₹3 lakh and ₹5 lakh for resident senior and super senior citizens, respectively.
The new regime is the default tax regime for FY 2025-26 (AY 2026-27). The following are the tax slabs and rates under the new regime.
| New Tax Regime Slabs | New Tax Regime Rates |
| Up to Rs. 4 lakh | Nil |
| Rs. 4 lakh to Rs. 8 lakh | 5% |
| Rs. 8 lakh to Rs. 12 lakh | 10% |
| Rs. 12 lakh to Rs. 16 lakh | 15% |
| Rs. 16 lakh to Rs. 20 lakh | 20% |
| Rs. 20 lakh to Rs. 24 lakh | 25% |
| Above Rs. 24 lakh | 30% |
Key Features of the New Regime:
| Income Tax Slabs | Income Tax Rate |
| Up to Rs. 2.5 lakh | Nil |
| Rs. 2.5 lakh to Rs. 5 lakh | 0.05 |
| Rs. 5 lakh to Rs. 10 lakh | 0.2 |
| Above Rs. 10 lakh | 0.3 |
Key Features of the Old Regime:
When the income under the new tax regime slightly exceeds the ₹12 lakh limit and is thereby subject to tax, marginal relief on rebate ensures that the increase in income does not result in disproportionate tax liability.
Illustration:
Particulars | Amount |
| Taxable income | Rs. 12,10,000 |
| Rebate limit (tax free income) | Rs. 12,00,000 |
| Income exceeding limit | Rs. 10,000 |
| Tax as per slab rates (on Rs. 12,10,000) | Rs. 61,500 |
| Tax payable after marginal relief | Rs. 10,400 |
In this example, although the calculated tax is higher, marginal relief restricts the tax payable to ₹10,000, which is equal to the additional income above ₹12 lakh.
While a standard deduction of ₹75,000 is allowed against salary under the new regime, the limit under the old regime is fixed at ₹50,000. Under both the regimes, standard deduction is available against salary unconditionally.
The following illustration shows the instance in which the tax liability can be made zero using standard deduction and rebate under the new regime. Mr X earns a salary income of ₹12.75 lakh in FY 2025-26 and opts for the new tax regime. After the standard deduction of ₹75,000, his taxable income will be ₹12 lakh. Here’s how the Section 87A rebate works:
| Slab | Amount | Tax |
| Up to ₹4 lakh | ₹4 lakh @ 0% | Nil |
| ₹4 lakh to ₹8 lakh | ₹4 lakh @ 5% | 20000 |
| ₹8 lakh to ₹12 lakh | ₹4 lakh @ 10% | 40000 |
| Total Tax Before Rebate | 60000 | |
| Rebate u/s 87A | -60000 | |
| Net Tax Liability | 0 | |
When your income crosses specified thresholds, you are liable to pay surcharge, which is calculated at a certain percentage of the income tax. Also, when your total income results in a tax liability, cess should be paid at 4% in all cases. The following table shows the surcharge levy at different rates.
| Income Limit | New Tax Regime | Old Tax Regime |
| Up to Rs. 50 lakh | Nil | Nil |
| Rs. 50 lakh to Rs. 1 Crore | 10% | 10% |
| Rs. 1 Crore to Rs. 2 Crore | 15% | 15% |
| Rs. 2 Crore to Rs. 5 Crore | 25% | 25% |
| Above Rs. 5 Crore | 25% | 37% |
There are no significant changes made in the income tax slabs announced in budget 2026. Therefore, the slab rates for FY 2026-27 remain the same.
| Income Tax Slabs | Income Tax Rate |
| Up to Rs. 3 lakh | Nil |
| Rs. 3 lakh to Rs. 5 lakh | 5% |
| Rs. 5 lakh to Rs. 10 lakh | 20% |
| Above Rs. 10 lakh | 30% |
| Income Tax Slabs | Income Tax Rate |
| Up to Rs. 5 lakh | Nil |
| Rs. 5 lakh to Rs. 10 lakh | 20% |
| Above Rs. 10 lakh | 30% |
While the most beneficial regime highly depends on your income and deduction levels, it can be perceived that the old regime suits the taxpayers who have numerous tax deductions and have done elaborate tax planning in advance; the new regime suits the taxpayers who do not have significant deductions to claim. The following table shows the major differences between the old and new regimes
| Feature | Old Tax Regime | New Tax Regime |
| Default Regime | No | Yes |
| Basic Exemption Limit | Rs. 2.5 lakh | Rs. 4 lakh |
| Rebate u/s 87A | Rs. 12,500 (income up to Rs. 5 lakh) | Rs. 60,000 (income up to Rs. 12 lakh) |
| Standard Deduction | Rs. 50,000 | Rs. 75,000 |
| Section 80C Deductions | Allowed | Not Allowed |
| HRA Exemption | Allowed | Not Allowed |
| Home loan interest (Self-occupied) | Allowed | Not Allowed |
| NPS Deduction | Fully Allowed | Only Employer Contribution |
| Set-off of House property losses | Allowed | Not Allowed |
| Section 80D Deduction | Allowed | Not Allowed |

The following steps can be undertaken to calculate the tax liability for FY 2025-26.
Mr Raj has a salary income of Rs. 15 lakhs. His taxable income and tax liability for FY 2025-26 (AY 2026-27) will be computed as follows under the new tax regime to save taxes:
| Particulars | Amount |
| Income From Salary | 1500000 |
| (-) Standard Deduction | -75000 |
| Taxable Income for FY 2025-26 (AY 2026-27) | 1425000 |
The tax liability of Mr. Raj will be calculated as follows:
| Income Tax Slabs | Tax Liability | |
| Up to Rs. 4 lakh | Rs. 4 lakh @ 0% | - |
| Rs. 4 lakh to Rs. 8 lakh | Rs. 4 lakh @ 5% | 20,000 |

| Long-term Capital Gains | 13% |

There are no differences between the tax slabs for women and men. Under the Indian Income Tax Act, assessees are taxed at par, irrespective of gender.
While there are no differences in taxation of NRIs under the new tax regime, the beneficial tax slabs available for resident senior citizens and super senior citizens under the old regime are not available for NRI assessees.
The default tax regime, basic exemption limit, and other provisions are often similar for individuals and HUF. Though the determination of residential status differs between individuals and HUF, the taxability, deduction eligibility, and other provisions remain similar in most cases.
After gathering all the necessary documents, it is necessary to choose the right ITR form depending on the income levels, assessee’s legal status, and other criteria. Filing the returns within the applicable due date can avoid late fees, penalties, delay in refund processing, and other adverse consequences.
