- In the new regime, you pay no income tax if your taxable income is up to ₹12 lakh. With the ₹75,000 standard deduction, that is a salary of up to ₹12.75 lakh.
- Your CTC can be higher still. On a typical structure, a CTC of up to about ₹13.66 lakh pays zero tax, because employer PF and gratuity are not taxed as salary.
- Just above the limit is a strip where almost every extra rupee goes in tax. A raise from ₹13.6 lakh to ₹14.4 lakh CTC leaves your monthly take-home flat.
- Other income counts too. ₹50,000 of FD interest on top of a ₹12.75 lakh salary brings a ₹52,000 tax bill.
When the rebate went up to ₹12 lakh, it became the most quoted line in Indian personal finance. And it is true. But almost everyone who asks about it is really asking something else: “My offer says ₹13 lakh. Do I pay tax?” or “If I get a raise past ₹12 lakh, do I lose the whole benefit?”
The answers depend on three numbers that are not the same thing: your CTC, your gross salary and your taxable income. Let’s walk through them, then look at the strange strip just above the limit where the rule bites hardest.
The rule in one line
Under the new tax regime for Tax Year 2026-27 (FY 2026-27), if your taxable income is ₹12 lakh or less, a rebate cancels your entire tax. The slab tax on ₹12 lakh is ₹60,000, and the rebate wipes all of it out.
Salaried people first get a ₹75,000 standard deduction, which comes off before tax is worked out. So a salary of ₹12.75 lakh becomes taxable income of exactly ₹12 lakh, and the tax is zero.
Note: the rebate is for residents and is part of the new regime only. In the old regime it stops at ₹5 lakh of taxable income.
Your CTC is not your salary
Here is the first surprise. The number on your offer letter, your CTC, includes money that is never paid to you as salary. Your employer’s PF contribution and the gratuity provision sit inside CTC, but they are not taxed as salary when they are credited.
On a common structure (basic pay at 40% of CTC, PF at 12% of basic, gratuity inside CTC), here is where a ₹12 lakh CTC goes in a year:
The gross salary here is ₹11,19,312, comfortably under ₹12.75 lakh, so the income tax is zero. The take-home is ₹88,276 a month.
Push the CTC up and the zero survives longer than most people expect. On this structure, the tax stays at zero until a CTC of about ₹13.66 lakh, the point where gross salary reaches ₹12.75 lakh.
The old regime would cost you about ₹10,000 a month here. To catch up, it would need roughly ₹5.7 lakh of deductions on top of the standard deduction, which very few salaried people have.
Open this in the salary calculator →The strip just above the line
Now the second surprise. What happens if your salary is ₹12.8 lakh, just ₹5,000 over the limit? Without any special rule, you would suddenly owe the full slab tax of about ₹60,000, which would be absurd. So the law adds marginal relief: your tax cannot be more than the amount by which your taxable income exceeds ₹12 lakh.
That stops the cliff, but look at what it means in practice. In that strip, almost every extra rupee you earn goes in tax, and the 4% cess is charged on top of that tax:
| Gross salary | Income tax (with cess) | What you keep |
|---|---|---|
| ₹12,75,000 | ₹0 | ₹12,75,000 |
| ₹12,80,000 | ₹5,200 | ₹12,74,800 |
| ₹13,00,000 | ₹26,000 | ₹12,74,000 |
| ₹13,25,000 | ₹52,000 | ₹12,73,000 |
| ₹13,45,000 | ₹72,800 | ₹12,72,200 |
| ₹13,50,000 | ₹74,100 | ₹12,75,900 |
| ₹14,00,000 | ₹81,900 | ₹13,18,100 |
From ₹12.75 lakh to about ₹13.45 lakh of salary, you keep slightly less as you earn more, because the cess is added on top of a tax that already takes every extra rupee. After about ₹13.46 lakh, the normal 15% slab takes over and each raise starts to count again.
Your PF still rises by ₹320 a month, so the raise is not wasted entirely. But your cash in hand stays flat, and that is the number most people budget with.
See this raise in the hike calculator →This matters when you negotiate. If an offer lands in this strip, the conversation is worth having in terms of take-home pay, not CTC. A raise to ₹15 lakh, for example, takes the monthly in-hand to ₹1,03,581.
What you can actually do about it
The new regime allows very few deductions, but one of them is made for exactly this situation: your employer’s contribution to NPS, which is deductible up to 14% of basic pay in the new regime. It moves part of your pay into your retirement account before tax is worked out.
Your monthly cash drops by about ₹2,000, but ₹56,000 a year lands in your NPS and the ₹32,099 tax disappears. Counting both, you are about ₹32,000 a year better off. NPS money is locked until retirement, with limited early withdrawals, so this suits money you would have saved anyway.
Try employer NPS in the salary calculator →Not every employer offers it, and the switch usually happens at the start of the year or at appraisal time, so it is worth asking HR about it early.
The trap outside your salary: other income
The third surprise catches people who are already safely under the limit. The ₹12 lakh test is on your total taxable income, not just your salary. FD interest, savings-account interest beyond the small exempt amount, rent from a flat and freelance income are all added on.
Say your salary is exactly ₹12.75 lakh, so you pay nothing, and your FDs earn ₹50,000 of interest in the year. Your taxable income is now ₹12.5 lakh. Marginal relief caps the tax at the ₹50,000 excess, and cess takes it to ₹52,000. That is more than the interest you earned.
Watch out: some income, such as profit on shares and mutual funds, is taxed at its own special rates, and the rebate may not cover tax on it. If you have large capital gains, check the treatment before counting on a zero bill.
The FD calculator works this out for you: enter your yearly salary and it adds the interest on top, so you can see the tax on the interest itself.
A 60-second check for your own salary
- Open the salary calculator and type your CTC.
- Set basic pay and PF to match your offer letter (they change how much of your CTC is taxed).
- Look at the gross salary and the tax under the new regime. If the gross is between ₹12.75 lakh and about ₹13.46 lakh, you are in the strip.
- Try adding employer NPS, then check the in-hand and the NPS amount together.
- Add any interest or rent you earn, using the FD calculator for deposits.
Frequently asked questions
Is a ₹12 lakh salary tax-free?
Yes, in the new regime. A salaried person with a gross salary of up to ₹12.75 lakh and no other income pays no income tax, because the ₹75,000 standard deduction brings taxable income to ₹12 lakh and the rebate cancels the tax on it.
Is a ₹13 lakh CTC tax-free?
Often, yes. CTC includes employer PF and gratuity, which are not taxed as salary. With basic pay at 40% of CTC and PF on the full basic, a ₹13 lakh CTC gives a gross salary of about ₹12.13 lakh, and the tax is zero. Your own structure decides it, so check with your numbers.
What is marginal relief?
It is the rule that stops tax jumping from zero to about ₹60,000 the moment your taxable income crosses ₹12 lakh. Your tax cannot be more than the amount by which your income is over ₹12 lakh. Cess of 4% is then added. It applies up to a taxable income of about ₹12.7 lakh.
Does the ₹12 lakh limit apply in the old regime?
No. In the old regime the rebate applies only up to ₹5 lakh of taxable income. Old-regime users keep deductions such as HRA and 80C instead.
Does FD interest count towards ₹12 lakh?
Yes. Interest is added to your other income. If it pushes your taxable income past ₹12 lakh, you pay tax on the excess and may lose the rebate entirely at higher amounts.
What does your CTC really pay?
