New Tax Regime Vs Old Tax Regime – Detailed Slab-wise Comparison For 2026

Choosing a tax regime is not as simple as it used to be. You used to be able to look at your salary and investments and pick a path.. Now with all the changes under the Income Tax Act 2025 you need to take a fresh look. The focus now is on making things simpler and helping people who earn a middle-class income.

Lets look at two colleagues, Rahul and Priya. They both earn an annual salary of Rs. 15,00,000 But they make different choices about their money.

Rahul likes to keep his money easy to access. He rents an apartment in Pune. Does not have a home loan. He also likes to invest in equity instead of traditional tax-saving schemes. The new tax regime is very appealing to Rahul because it is simple.

The new tax regime is the default option now. If Rahul sticks with it his tax calculation starts with a deduction of Rs. 75,000. This brings his salary down to Rs. 14,25,000. Under this structure Rahul cannot claim any exemptions for his house rent or life insurance premiums or medical policies.

The tax rates for the tax regime are applied to Rahuls taxable income of Rs. 14,25,000. The first Rs. 4,00,000 Is tax-free. The next block, from Rs. 4,00,001 To Rs. 8,00,000 Is taxed at 5percentage, which's Rs. 20,000. The third block, from Rs. 8,00,001 To Rs. 12,00,000 Is taxed at 10percentage which adds Rs. 40,000 To his tax bill. The last part of his income from Rs. 12,00,001 To Rs. 14,25,000 Is taxed at 15percentage, which's Rs. 33,750.

If we add all these up Rahuls base tax is Rs. 93,750. After adding the 4percentage health and education cess his final tax liability is Rs. 97,500. Rahul can file his return easily without needing to track rent receipts or investment proofs.

Now lets look at Priya. She likes to invest in term fixed investments and owns property. She pays a home loan for her apartment. Contributes to the Public Provident Fund. She also pays premium amounts for family health insurance. Because of these commitments Priya chooses the old tax regime.

For Priya the math is different under the system. She starts with a standard deduction of Rs. 50,000.. She can claim a lot of exemptions. She claims Rs. 1,50,000 Under Section 80C for her fund and life insurance. She also claims Rs. 25,000 For health insurance under Section 80D.. Because she owns her house she deducts Rs. 2,00,000 Under Section 24b for home loan interest.

If we add up all her deductions Priya reduces her income of Rs. 15,00,000 By Rs. 4,25,000 Leaving her with a taxable income of Rs. 10,75,000. The old regime tax rates apply to this amount. The first Rs. 2,50,000 Is exempt from tax. The next block, from Rs. 2,50,001 To Rs. 5,00,000, Is taxed at 5percentage, which's Rs. 12,500. The large chunk, from Rs. 5,00,001 To Rs. 10,00,000 Is taxed at 20percentage, which's Rs. 1,00,000. The remaining Rs. 75,000 Is taxed at 30percentage, which's Rs. 22,500.

Priyas total base tax under the regime is Rs. 1,35,000. After adding the 4percentage cess her total tax liability is Rs. 1,40,400. Priya pays Rs. 42,900 Than Rahul. For her to pay the amount of tax as Rahul she would need to find additional valid exemptions.

To compare the two tax regimes lets look at the tax slabs.

New Tax Regime Slabs

1. Income up to Rs. 4,00,000 Is taxed at Nil
2. Income from Rs. 4,00,001 To Rs. 8,00,000 Is taxed at 5percentage
3. Income from Rs. 8,00,001 To Rs. 12,00,000 Is taxed at 10percentage
4. Income from Rs. 12,00,001 To Rs. 16,00,000 Is taxed at 15percentage
5. Income from Rs. 16,00,001 To Rs. 20,00,000 Is taxed at 20percentage
6. Income from Rs. 20,00,001 To Rs. 24,00,000 Is taxed at 25percentage
7. Income above Rs. 24,00,000 Is taxed at 30percentage

Old Tax Regime Slabs for Individuals Below 60 Years

1. Income up to Rs. 2,50,000 Is taxed at Nil
2. Income from Rs. 2,50,001 To Rs. 5,00,000 Is taxed at 5percentage
3. Income from Rs. 5,00,001 To Rs. 10,00,000 Is taxed at 20percentage
4. Income above Rs. 10,00,000 Is taxed at 30percentage

One of the things about the new regime is the enhanced Section 87A rebate. If your net taxable income is under Rs. 12,00,000 Under the regime your tax liability drops to zero because of a maximum rebate up to Rs. 60,000. When you combine this rebate with the Rs. 75,000 Deduction, anyone earning a gross salary up to Rs. 12,75,000 Pays zero tax under the regime as long as they have no other income streams. Under the regime the zero-tax threshold is much lower protecting income only up to Rs. 5,00,000 With a rebate of Rs. 12,500.

What if you earn a more than Rs. 12,00,000? Suppose an employee earns an income of Rs. 12,10,000. Under calculations they would lose the full rebate and face a big tax bill for earning just Rs. 10,000 More than the limit. To prevent this financial shock there are marginal relief rules. The tax department makes sure that the extra tax you pay cannot exceed the income you earned over the limit. Of losing the whole benefit the individual pays a lower tax amount that matches the excess income profile making the transition smoother.

There are an other things to keep in mind for 2026. For example if you like investing in funds you can no longer claim deductions for interest expenditure incurred to earn dividend or mutual fund income. The government has also made it easier to correct mistakes on your returns without facing harsh penalties.

The choice of tax regime depends on your lifestyle. If you do not want your savings locked up in insurance plans or tax-saver mutual funds or long-term housing debt the new regime offers rates and more cash flow. If you are already locked into term financial commitments, like home loans the old regime might still be a good option but the break-even point is much higher now. Taking the time to calculate your income under both regimes ensures you do not lose money when it is time to file your taxes.
