Neither regime is best for everyone. The new regime has lower rates but few deductions. The old regime has higher rates but allows HRA, home loan interest and 80C. Add up your real deductions, then compare the tax under both. At a ₹15 lakh income, the old regime needs about ₹6 lakh of deductions to win.
Key Facts
- The new tax regime is the default. You stay in it unless you choose the old regime.
- New regime slabs run from nil (up to ₹4 lakh) to 30% (above ₹24 lakh).
- A resident individual can pay zero tax on taxable income up to ₹12 lakh under the new regime. Salary up to ₹12.75 lakh can qualify.
- On a ₹15 lakh salary, break-even needs about ₹6 lakh of deductions and exemptions.
- From 1 April 2026, the Income Tax Act, 2025 begins. Section 80C is now Section 123. The ₹1.5 lakh limit stays.
Two people earn the same ₹15 lakh salary. One saves about ₹90,000 in tax under the new regime. The other saves about ₹25,000 under the old regime. How is that possible? Because tax depends on more than salary. It also depends on rent, home loan, insurance and investments. A tax regime is simply a set of tax rules, and India has two. Many salaried people accept whatever HR picks. That can cost real money. This guide explains both regimes in plain words, with rupee examples and a four-step check.
What is the difference between the new and old tax regime?
Think of two shops. One shop has low prices but gives no discount. The other has higher prices but gives many discounts. The cheaper shop depends on how many discounts you can claim. Tax works the same way.
The new regime has lower tax rates. But it allows very few deductions. A deduction is an amount the law lets you subtract from your income before tax. The old regime has higher rates. But it lets you reduce your taxable income with 80C, health insurance, HRA and home loan interest.
| Feature | New regime (default) | Old regime |
|---|---|---|
| Tax rates | Lower | Higher |
| Basic exemption limit | ₹4 lakh | ₹2.5 lakh |
| Standard deduction (salaried) | ₹75,000 | ₹50,000 |
| 80C, health insurance, HRA, home loan interest | Mostly not allowed | Allowed within limits |
| Employer NPS contribution | Allowed within limits | Allowed within limits |
| Usually suits | People with few deductions | People with large deductions and exemptions |
The new regime is now the default. If you choose nothing, you are in the new regime. That suits many people. But renters and home loan holders should check the numbers first.
What are the new regime tax slabs for 2026?
These slabs apply to your taxable income, which is income after allowed deductions.
| Taxable income | Tax rate |
|---|---|
| Up 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% |
| Above ₹24 lakh | 30% |
There is also an important update. The Income Tax Act, 2025 takes effect from 1 April 2026. “Financial Year” becomes “Tax Year”. Section numbers also change. Old Section 80C becomes Section 123. Old Section 87A becomes Section 156. But the limits, such as ₹1.5 lakh, stay the same. Only the numbers change, so do not worry when you see a new section number.
If I am in the 30% slab, do I pay 30% on my whole salary?
No. This is the most common calculation mistake. A slab rate applies only to the part of income inside that slab. Take ₹12 lakh of taxable income under the old regime.
| Part of ₹12 lakh | Rate | Tax |
|---|---|---|
| First ₹2.5 lakh | Nil | ₹0 |
| Next ₹2.5 lakh | 5% | ₹12,500 |
| Next ₹5 lakh | 20% | ₹1,00,000 |
| Last ₹2 lakh | 30% | ₹60,000 |
| Total before cess | ₹1,72,500 | |
| With 4% cess | about ₹1,79,400 |
A flat 30% would be ₹3.6 lakh. The real tax is only about ₹1.79 lakh. Cess is a 4% extra charge on your tax for health and education. So always calculate slab by slab. Then compare.
Is ₹12 lakh income really zero tax?
Partly. Under the new regime, a resident individual gets a rebate under Section 87A. In the new Act, this is Section 156. The rebate makes tax zero if taxable income is up to ₹12 lakh.
Salaried people also get a ₹75,000 standard deduction. So a salary of ₹12.75 lakh can show zero tax. This works only when you have no other taxable income.
What happens at a ₹13 lakh salary?
Many people fear a sudden big tax. That does not happen. Marginal relief protects you. It means you never pay more tax than the income above ₹12 lakh.
Here is the sum. ₹13 lakh minus ₹75,000 gives taxable income of ₹12.25 lakh. Tax is limited to ₹25,000 (the amount above ₹12 lakh). Add 4% cess, and you pay about ₹26,000. So do not turn down a salary hike out of slab fear.
What about mutual fund gains, FD interest and rent?
Take a person with a ₹10 lakh salary who books profit in an equity mutual fund. The salary may attract zero tax. But equity gains follow their own rates. Short-term gains are taxed at 20%. Long-term gains above ₹1.25 lakh a year are taxed at 12.5%. The Section 87A rebate does not normally cover these special-rate gains. So check the tax before you redeem.
FD interest and rent are different. They join your taxable income and get taxed at your slab rate. So when you compare regimes, add your other income too.
Karthik vs Priya: same salary, different answer
Here is a simple example. Both earn ₹15 lakh. Karthik lives with his parents. Priya pays rent in Chennai and has a home loan on a house in her hometown. These numbers are illustrative and simplified.
| ₹15 lakh salary | Karthik | Priya |
|---|---|---|
| Deductions and exemptions (besides standard deduction) | ₹2.25 lakh (80C, health insurance, NPS) | ₹6.65 lakh (same three, plus HRA ₹2.4 lakh and home loan interest ₹2 lakh) |
| Old regime tax (with cess) | about ₹1.87 lakh | about ₹72,000 |
| New regime tax (with cess) | about ₹97,500 | about ₹97,500 |
| Better choice | New regime, saves about ₹90,000 | Old regime, saves about ₹25,000 |
Karthik claims 80C of ₹1.5 lakh, health insurance of ₹25,000 and NPS of ₹50,000. That totals ₹2.25 lakh. It is not enough to beat the new regime. Priya has the same three deductions. But she also has HRA (house rent allowance) of about ₹2.4 lakh and home loan interest of ₹2 lakh. Her total reaches about ₹6.65 lakh. So the old regime wins for her.
I have 80C investments. Is the old regime always better?
No. This is the biggest misconception. Section 80C gives only ₹1.5 lakh. That rarely covers the gap. Look at the break-even numbers instead.
| Yearly income | Deductions and exemptions needed (including standard deduction) |
|---|---|
| ₹15 lakh | about ₹6 lakh |
| ₹20 lakh | about ₹7.6 lakh |
| ₹25 lakh | about ₹8.5 lakh |
Very few people reach these levels. You usually need a big HRA claim or home loan interest to get there. So never pick the old regime just because you have “some 80C”. Calculate with your real numbers.
What is the hidden benefit in the new regime?
Employer NPS contribution. NPS is the National Pension System, a government-regulated retirement account. If your employer contributes to your NPS, you can get a deduction even in the new regime. There is a limit. Ask HR whether your salary structure can use it. It helps your tax and your retirement savings together. Please verify the latest limit from the official Income Tax Department source.
Can I change my regime later?
Yes, in most salaried cases. What you tell your employer only guides monthly TDS. TDS means tax deducted at source, which your employer cuts from your salary. A salaried person with no business income can choose the final regime while filing the return.
Business or professional income follows stricter rules for switching. If you have such income, take advice before you decide.
Should I stop ELSS or insurance if I choose the new regime?
Do not stop a good product only because the tax benefit is gone. ELSS (Equity Linked Savings Scheme) is an equity mutual fund with a three-year lock-in. If it funds a real goal, like your child’s education, it can still make sense. Term insurance protects your family whether or not it saves tax.
It is a good time to review any product bought only for tax. But do not stop a useful investment in a panic. Tax is a bonus, never the main reason.
How do I pick my regime? 4 simple steps
- Note down your gross salary and any other income.
- List the deductions and exemptions you can truly claim: 80C, health insurance, NPS, HRA and home loan interest.
- Calculate tax under both regimes. Use the Income Tax Department calculator or a trusted tax calculator.
- Tell your employer the better regime. Then your TDS is correct.

Frequently asked questions
Which is better in 2026, the new tax regime or the old tax regime?
Neither regime is better for everyone. The new regime has lower tax rates but allows few deductions. The old regime has higher rates but allows HRA, home loan interest, 80C and more. Calculate your tax under both. If your deductions and exemptions are large, the old regime may win. Otherwise, the new regime usually costs less.
Is income up to ₹12 lakh really tax free?
Under the new regime, a resident individual pays zero tax on taxable income up to ₹12 lakh. This is because of the Section 87A rebate. Salaried people also get a ₹75,000 standard deduction. So salary up to ₹12.75 lakh can show zero tax, if there is no other income. Special-rate capital gains are taxed separately.
If I am in the 30% slab, do I pay 30% on my whole salary?
No. Each slab rate applies only to the part of your income that falls inside that slab. For example, under the old regime, ₹12 lakh of taxable income gives about ₹1.79 lakh of tax including cess. A flat 30% would be ₹3.6 lakh. Always calculate slab by slab, then compare.
Can I change my tax regime after telling my employer?
Yes, in most cases. A salaried person with no business income can choose a regime while filing the income tax return. This can differ from the one used for TDS. The choice you tell your employer only guides monthly tax deduction. Business or professional income follows stricter switching rules, so get advice first.
How many deductions do I need for the old regime to win?
It depends on your income. For a ₹15 lakh income, you need roughly ₹6 lakh of total deductions and exemptions, including the standard deduction. For ₹20 lakh, about ₹7.6 lakh. For ₹25 lakh, about ₹8.5 lakh. Section 80C alone gives only ₹1.5 lakh, so most people fall short.
Do I still get a tax benefit for employer NPS in the new regime?
Yes. An employer’s contribution to your NPS account can get a deduction even in the new regime. A limit applies, set by the Income Tax Department. Ask your HR team whether your salary structure allows it. Please verify the latest limit from the official source before you restructure your pay.
Should I stop my ELSS or insurance if I choose the new regime?
Do not stop a good product only because the tax benefit is gone. An ELSS is an equity mutual fund with a three-year lock-in. If it supports a real goal like your child’s education, it can still make sense. Term insurance protects your family, whether or not it saves tax. Review each product for its purpose.
