Old vs New Tax Regime Which is Better? With Calculator

One of the important questions while filing ITR (Income Tax Return) is Which is better Old vs New Tax Regime? Why New tax regime was introduced and is old tax regime still beneficial? We will answer all these queries in this post.

Here’s the short answer: if you can claim deductions worth roughly ₹6 lakh or more (HRA, 80C, 80D, home loan interest, etc.), the Old Tax Regime usually still works out cheaper. But for FY 2025-26, the New Tax Regime got a major upgrade — thanks to a higher Section 87A rebate, your income is completely tax-free up to ₹12 lakh (₹12.75 lakh for salaried employees, after the standard deduction). That’s pulled a lot of middle-income taxpayers toward the new regime, even those who used to save more under the old one.

Below, we’ll walk through both slab structures, show real income examples, and help you figure out which regime actually saves you more this year.

You can make Rs. 6 Lakh of investments or deductions based on this article of how to save income tax. So even if your income is Rs. 11 Lakh in FY 2024-25, your taxable income will be Rs. 5 Lakh based on Old Tax Regime on which you don’t have to pay any tax due to Tax Rebate under Section 87A.

What is Difference between Old Regime and New Regime?

There are 2 major differences between Old regime and New regime:

• New Tax Regime have reduced tax slab rates compared to Old Tax Regime
• New Tax Regime does not allow deductions (except Standard Deduction of Rs. 75,000 and few more deductions mentioned here), whereas old regime allows all other deductions to save income tax

Let us see the Slab Rates in both tax regimes:

Old Regime Tax Slab Rates

So as seen above, if your income is above Rs. 10 Lakh in FY, you belong to 30% slab in India and pay tax according to income tax calculation.

Above slab rates belong to people of age within 60 years, read more about Income Tax Slab Rates 2024-25 to know more about senior citizens tax slab rates.

New Tax Regime Tax Slab Rates (FY 2025-26)

These slabs look higher than before at first glance, but don’t worry — the Section 87A rebate below cancels out tax completely for most middle-income earners.

In New tax regime, the slab rates are reduced compared to old tax regime. But this comes with a condition that you cannot claim any deductions while calculating and paying income tax.

Why Income up to ₹12 Lakh is Tax-Free in the New Regime

This is the single biggest change for FY 2025-26. Under Section 87A, if your taxable income is ₹12 lakh or below, you get a rebate of up to ₹60,000 — which wipes out your entire tax liability under the new regime.

For salaried employees, the standard deduction of ₹75,000 pushes this even further. That means:

• Gross salary up to ₹12.75 lakh = zero tax under the new regime, with no investments or deductions needed.

Here’s how the math works for someone earning exactly ₹12.75 lakh:

1. Taxable income after standard deduction: ₹12.75L − ₹75,000 = ₹12L
2. Tax as per slab rates: ₹60,000
3. Section 87A rebate: ₹60,000
4. Net tax payable: ₹0

One thing to watch out for — this rebate disappears entirely once your taxable income crosses ₹12 lakh, but marginal relief kicks in so you don’t face a sudden jump in tax. So someone earning ₹12.1 lakh doesn’t suddenly owe tax on the full amount – they only pay tax on the amount above ₹12 lakh.

Old vs New Tax Regime Calculator Online

You can easily calculate your income tax based on the Old vs New Tax Regime Calculator I have made for you online.

Use below calculator to check your income tax:

By using this income tax calculator, you can easily calculate your income tax and decide whether you should select old or new tax regime to calculate and pay income tax.

Below is the example of tax calculation on income = Rs. 10 Lakh in FY 2024-25 without any investments or deductions:

So you pay Rs. 1,06,600 tax with old tax regime and Rs. 44,200 with new tax regime. Standard Deduction of Rs. 50,000 is included in old tax regime and Rs. 75,000 is included in new tax regime, if salaried or pensioner option is selected.

Let us now see another example where you make more deductions – Rs. 1.5 Lakh in Section 80C, Rs. 1 Lakh as HRA (House Rent Allowance) and Rs. 50,000 in Section 80CCD(1B):

So as seen above, tax with Old tax regime is reduced to Rs. 44,200 and with new tax regime as well the income tax is Rs. 44,200.

And this is how you can take advantage to claiming more deductions to save income tax with old tax regime.

What is the benefit of new tax regime?

Even if we don’t get deduction options in new tax regime, it does not mean that new tax regime is of no use.

Below are some benefits of new tax regime:

• Standard deduction of Rs. 75,000 is available in new tax regime from FY 2024-25 onwards
• No tax on income up to Rs. 7.75 Lakh from FY 2024-25 onwards due to Standard Deduction and Tax Rebate in new regime
• Transport allowance can be claimed in case of specially-abled person
• Conveyance allowance for employees received to meet conveyance expenditures
• Compensation received for cost of travel or tour
• Daily Allowance received as compensation for cost of living in some other place compared to regular place of working
• Deduction for employer’s contribution in NPS Account under Section 80CCD(2)

Old vs New Tax Regime Which is Better?

So far we have understood that if we claim deductions, we can save more income tax with old tax regime. Let us take more examples to see more comparison stats.

Let’s say you make maximum deductions in various sections as mentioned below:

1. Standard Deduction – Rs. 50,000
2. Section 80C – Rs. 1,50,000
3. Section 80D – Rs. 50,000
4. Section 80CCD(1B) – Rs. 50,000
5. HRA (House Rent Allowance) – Rs. 1,00,000
6. Section 24 – Rs. 2,00,000

So total deductions is Rs. 6 Lakh.

Let’s use it to calculate tax and compare old and new tax regime with various incomes:

Income Tax with Old and New Tax Regime (FY 2025-26)

Assuming Rs. 6 Lakh Deductions with Old Tax Regime and Rs. 75,000 Standard Deduction with New Tax Regime:

Old regime figures assume ₹6 lakh in deductions (80C, 80D, HRA, Section 24, etc.). New regime figures assume no deductions, since most aren’t allowed under this regime.

Notice the shift: up to around ₹15 lakh, the Old Regime is still cheaper if you actually claim close to ₹6 lakh in deductions. But past that point, the New Regime’s lower slab rates start winning — even with zero investments..

Old vs New Regime: Which One Actually Wins Now?

This isn’t a one-size-fits-all answer anymore. It depends on your income level and how much you can genuinely invest:

• Income up to ₹12.75 lakh (salaried): New Regime wins easily — it’s tax-free by default, no paperwork or investment needed.
• Income between ₹13 lakh and ~₹15.5 lakh: Old Regime still wins, but only if you can claim close to ₹6 lakh in deductions (HRA, 80C, 80D, home loan interest). If you can’t hit that number, New Regime is usually cheaper.
• Income above ₹16 lakh: New Regime tends to win again, even with full deductions claimed under the old regime, because its slab rates are meaningfully lower at higher income levels with New Tax Regime.

The old advice of “always pick Old Regime if you invest” doesn’t hold as strongly anymore. Calculate your actual numbers through a calculator before deciding — the crossover point depends heavily on your specific deduction amount.

Frequently Asked Questions

Is income up to ₹12 lakh really tax-free under the new regime?

Yes, for FY 2025-26. The Section 87A rebate of up to ₹60,000 cancels out the tax on taxable income up to ₹12 lakh. For salaried employees, the ₹75,000 standard deduction raises this to ₹12.75 lakh in gross salary.

Can I switch between Old and New Tax Regime every year?

If you’re a salaried employee with no business income, yes — you can choose whichever regime suits you each year when filing your ITR. Those with business or professional income have more restrictions on switching back and forth.

Which regime is better if I have a home loan?

If you’re paying significant home loan interest (claimed under Section 24) along with other deductions like 80C and HRA, the Old Regime often still works out better up to roughly ₹15–15.5 lakh income. Above that, run both calculations since the New Regime’s lower slabs may still win.

Is the New Tax Regime the default now?

Yes. Since FY 2023-24, the New Tax Regime is the default option. If you want to use the Old Regime, you need to actively select it while filing your ITR.

Do senior citizens get extra benefit in the New Regime?

No. Unlike the Old Regime, which gives senior citizens (60+) and super senior citizens (80+) a higher basic exemption limit, the New Regime has the same ₹4 lakh exemption limit for everyone, regardless of age.

Conclusion

For FY 2025-26, the answer to “Old vs New Tax Regime” isn’t as simple as it used to be. If your income is under ₹12.75 lakh, the New Regime is almost certainly your best bet — it’s tax-free with zero paperwork. If you’re earning more and can genuinely claim deductions close to ₹6 lakh, the Old Regime may still save you money, but only up to around ₹15–15.5 lakh income.

Don’t rely on last year’s assumption — the math has changed. Plug your actual income and deductions into the income tax calculator before you file, and pick the regime based on real numbers, not habit.
