Old vs New Tax Regime FY 2026-27: The Break-Even Deduction Number
Budget 2026 changed nothing: the slabs, the Rs 60,000 Section 87A rebate and the Rs 75,000 standard deduction all carry forward from last year. For a salaried taxpayer, gross salary up to Rs 12.75 lakh means zero tax under the New Regime, and below that level the Old Regime effectively cannot compete. Above it, the question becomes arithmetic — how much you can actually deduct. On our computation you need roughly Rs 5.44 lakh of deductions at Rs 15 lakh gross, about Rs 7.09 lakh at Rs 20 lakh, and above roughly Rs 24 lakh the break-even settles at about Rs 8 lakh and stops moving. Most salaried filers without a large home loan do not reach those numbers, which is why the New Regime wins by default for the majority.

Every year this decision gets framed as a philosophical one — saver versus spender, discipline versus flexibility. It is not. It is a subtraction problem with one number on each side, and once you know your own deduction total the answer is arithmetic. What follows is that arithmetic, computed at each salary level for FY 2026-27, with the exact figure at which the Old Regime starts winning.
What Budget 2026 Changed: Nothing
The Union Budget presented on 1 February 2026 made no changes to the personal income tax slabs under either regime, left the Section 87A rebate untouched, and kept the standard deduction where it was. The structure introduced in Budget 2025 simply carries forward into FY 2026-27.
For the record, the New Regime slabs for FY 2026-27 are: nil up to Rs 4 lakh; 5% from Rs 4 to 8 lakh; 10% from Rs 8 to 12 lakh; 15% from Rs 12 to 16 lakh; 20% from Rs 16 to 20 lakh; 25% from Rs 20 to 24 lakh; and 30% above Rs 24 lakh. The standard deduction is Rs 75,000 and the Section 87A rebate is up to Rs 60,000 where net taxable income does not exceed Rs 12 lakh.
The Old Regime is unchanged too: nil up to Rs 2.5 lakh, 5% from Rs 2.5 to 5 lakh, 20% from Rs 5 to 10 lakh, and 30% above Rs 10 lakh, with a Rs 50,000 standard deduction and a rebate of up to Rs 12,500 where taxable income does not exceed Rs 5 lakh. Health and education cess of 4% applies on top under both.
I am on the New Regime, and I will give the unglamorous reason first: it is far easier to understand, and a tax structure you actually understand is one you can plan around. But simplicity is not the whole case. For most salaried people earning below roughly Rs 25 lakh a year, the arithmetic points the same way, and the cleanest way to see it is the break-even deduction — the amount you would have to legitimately claim under the Old Regime just to land at the same tax bill. On FY 2026-27 numbers, that break-even is about Rs 5.44 lakh at Rs 15 lakh of gross salary, about Rs 7.08 lakh at Rs 20 lakh, and Rs 8 lakh at Rs 25 lakh. Above Rs 24 lakh it stops moving at all, because both regimes are taxing the top rupee at 30 per cent by then.
Now hold that against what a salaried person can realistically assemble. A full Rs 1.5 lakh of 80C, the extra Rs 50,000 of 80CCD(1B) and Rs 25,000 of health premium comes to Rs 2.25 lakh — less than half of what is needed at Rs 15 lakh. Add a metro HRA exemption of about Rs 2.85 lakh, which is what Rs 30,000 a month of rent produces on that salary, and you reach Rs 5.10 lakh — still short. It is only when you add Rs 2 lakh of home-loan interest under Section 24(b) that the total reaches Rs 7.10 lakh and clears the bar comfortably.
That is the real point, and it is not that the New Regime is generous. It is that the Old Regime’s deduction menu is finite, and most people cannot fill it. Below Rs 25 lakh, unless you are both renting expensively and servicing a large home loan, the Old Regime asks you to lock money into instruments you may not otherwise want in order to chase a deduction you will not fully use. Beyond the arithmetic it comes down to personal preference about how you want to hold your money — but the preference should be made after running your own break-even number, not instead of it.
The Break-Even Table
Here is the actual answer. The table below shows, at each gross salary level, the tax payable under the New Regime, the tax payable under the Old Regime if you claimed no deductions beyond its standard deduction, and the level of additional deductions at which the two regimes produce the same tax.
| Gross salary | Tax: New Regime | Tax: Old Regime, no deductions | Break-even deductions |
|---|---|---|---|
| Rs 7,00,000 | Nil | Rs 44,200 | Rs 1,50,000 |
| Rs 10,00,000 | Nil | Rs 1,06,600 | Rs 4,50,000 |
| Rs 12,75,000 | Nil | Rs 1,87,200 | Rs 7,25,000 |
| Rs 15,00,000 | Rs 97,500 | Rs 2,57,400 | Rs 5,44,000 |
| Rs 20,00,000 | Rs 1,92,400 | Rs 4,13,400 | Rs 7,08,500 |
| Rs 25,00,000 | Rs 3,19,800 | Rs 5,69,400 | Rs 8,00,000 |
| Rs 30,00,000 | Rs 4,75,800 | Rs 7,25,400 | Rs 8,00,000 |
| Rs 50,00,000 | Rs 10,99,800 | Rs 13,49,400 | Rs 8,00,000 |
Two features of that table are worth pausing on, because they are the whole story.
Feature One: Below Rs 12.75 Lakh, There Is No Contest
At Rs 7 lakh, Rs 10 lakh and Rs 12.75 lakh of gross salary, the New Regime produces zero tax. Zero is not a number the Old Regime can beat — it can only match it, and only by finding enough deductions to wipe out the liability entirely. At Rs 12.75 lakh that would take Rs 7.25 lakh of deductions to reach the same zero.
So if your gross salary is at or below roughly Rs 12.75 lakh, the decision is made for you. The rebate plus the standard deduction is simply a better deal than any realistic combination of 80C, 80D and the rest. There is no analysis to do.
What I see is that this is not really a knowledge gap. It is a generational one. The generation before ours genuinely believes insurance is both protection and a sound investment, and that belief is not irrational given the world they saved in — LIC still holds about 36.6 per cent of individual new business premium and roughly 56.7 per cent of first-year premium income industry-wide in FY 2026, which tells you how deep the habit runs. My own generation is arriving at the opposite structure: buy the protection separately and cheaply, and invest the rest yourself, usually in equity, with the intention that the pot doubles as an emergency reserve after five to ten years.
Put numbers on it and the gap is not subtle. A traditional endowment realistically returns somewhere between about 5 and 6.5 per cent a year. Take Rs 50,000 a year for twenty years: at 5.5 per cent that is roughly Rs 18.4 lakh at maturity, against Rs 10 lakh paid in, and the life cover attached to it is usually a few lakh. The alternative is a Rs 1 crore term plan, which costs a healthy 30-year-old non-smoker somewhere around Rs 9,500 to Rs 12,000 a year — and, since individual life insurance became GST-exempt on 22 September 2025, the quoted premium is now the premium you pay. That leaves about Rs 40,000 a year to invest. At 11 per cent over the same twenty years that grows to roughly Rs 28.5 lakh, or about Rs 26.1 lakh after equity LTCG at 12.5 per cent on gains above the Rs 1.25 lakh annual exemption. Ten times the cover, and roughly Rs 7.7 lakh more money, from the same Rs 50,000 a year.
The liquidity point matters just as much, and it is the one the younger approach is really buying. Surrender an endowment early and the guaranteed surrender value is 30 per cent of premiums paid in year two, 35 per cent in year three and 50 per cent from years four to seven, under the IRDAI norms effective October 2024. A mutual fund is worth what it is worth on the day you sell. And under the New Regime, where none of this is deductible anyway, the tax argument that once justified the endowment has simply been removed. The product now has to win on returns and liquidity alone. On the numbers above it does not — but I would still put this down to generational preference more than to arithmetic, because the people still buying endowments are not, in the main, people who have run these numbers and disagreed with them.
Feature Two: Above Rs 24 Lakh, the Number Stops Moving
Look at the last three rows. At Rs 25 lakh, Rs 30 lakh and Rs 50 lakh of gross salary, the break-even is the same figure: Rs 8 lakh of deductions. That is not a coincidence or a rounding artefact — it is structural.
Once your income is above Rs 24 lakh, every additional rupee is taxed at 30% under both regimes. The marginal rate is identical, so the gap between the two regimes stops widening and freezes at a constant amount. From that point onward, the deduction total you need to justify the Old Regime is a fixed Rs 8 lakh, whether you earn Rs 25 lakh or Rs 50 lakh.
That gives high earners a single number to test themselves against. Add up your realistic annual deductions: Rs 1.5 lakh of 80C, Rs 50,000 of 80CCD(1B), up to Rs 2 lakh of home loan interest under Section 24(b), your 80D health premium, and your HRA exemption if you rent. If the total clears Rs 8 lakh, the Old Regime is worth computing properly. If it does not, the New Regime wins and no amount of additional tax-saving product purchases will change that — each rupee of deduction is only worth about 30 paise, and you had to spend the rupee to get it.
This matches what I see, and I would put it more strongly: the regime question has stopped being an income question and become a housing question. The dividing line is no longer what you earn. It is whether you rent expensively in a metro, service a large home loan, or neither. Someone earning Rs 20 lakh with a Rs 60 lakh loan and a Rs 40,000 monthly rent during construction can plausibly get past the Rs 7 lakh mark and belongs on the Old Regime. Someone earning the same Rs 20 lakh who lives in an owned, unencumbered home has no realistic path there and belongs on the New. Same income, opposite answer.
Two things are pulling in different directions right now. From FY 2026-27 the 50 per cent HRA metro classification has been widened from four cities to eight, adding Bengaluru, Pune, Hyderabad and Ahmedabad — notified under the Income-tax Rules, 2026, and applying to salary earned on or after 1 April 2026, not to the return you filed this July. That strengthens the Old Regime case for renters in exactly the cities where the salaried base has grown fastest: on a Rs 10 lakh basic where the 40 per cent cap was the binding constraint, the extra exemption is worth around Rs 31,000 a year to someone in the 30 per cent slab. Pulling the other way, the Section 24(b) deduction for a self-occupied property has been stuck at Rs 2 lakh while property prices and ticket sizes have risen sharply, so a buyer taking a loan today exhausts that Rs 2 lakh in the first year and gets no further recognition for the rest of the interest. The result is that the Old Regime’s housing advantage is strongest for renters and for people already several years into a loan, and weakest for the first-time buyer who has just taken on the largest housing cost of their life.
So the sorting is real, but it is not permanent. Your housing situation changes — you buy, you finish construction, you prepay, you move cities — and the regime that suited you last year may not this year. This is one decision worth re-running annually rather than setting once and forgetting.

The Rs 12 Lakh Cliff and Marginal Relief
One structural quirk deserves attention because it looks alarming and is not. The Section 87A rebate applies where net taxable income does not exceed Rs 12 lakh. Cross that threshold by a rupee and, on a naive reading, you lose the entire Rs 60,000 rebate — a Rs 60,000-plus tax jump for one rupee of extra income.
The law anticipates this. Marginal relief ensures the additional tax payable cannot exceed the additional income earned above Rs 12 lakh. So income just above the threshold is taxed very heavily at the margin until the relief tapers out, but you are never left worse off in absolute terms than someone sitting exactly at Rs 12 lakh.
The practical implication is narrow but real: if your taxable income is going to land just above Rs 12 lakh, an additional deductible contribution that brings you back under the threshold is unusually valuable — far more valuable than the same contribution at any other income level. It is the one place in the structure where a small action produces a disproportionate result.
How to Actually Decide
If gross salary is at or under about Rs 12.75 lakh, choose the New Regime and stop. Nothing else in this article applies to you.
Not what you could theoretically claim. Real 80C contributions, real 80D premium, real home loan interest, real HRA exemption, real 80CCD(1B).
Use the table above. Above Rs 24 lakh the target is a flat Rs 8 lakh.
Salaried filers without business income can choose the regime each year at filing, so a declaration given to your employer for TDS is not binding on your final return.
For the mechanics of filing under whichever regime you pick, see our step-by-step ITR guide for salaried filers, and for last year’s comparison including the Section 87A capital gains issue, our FY 2025-26 regime guide.
- Budget 2026 made no changes to slabs, the Section 87A rebate, or the standard deduction. The Budget 2025 structure carries into FY 2026-27.
- New Regime FY 2026-27: nil to Rs 4L, 5% to Rs 8L, 10% to Rs 12L, 15% to Rs 16L, 20% to Rs 20L, 25% to Rs 24L, 30% above. Standard deduction Rs 75,000; rebate up to Rs 60,000 where taxable income is within Rs 12 lakh.
- Salaried gross up to about Rs 12.75 lakh means zero tax under the New Regime — the Old Regime cannot beat zero.
- Break-even deductions: about Rs 5.44 lakh at Rs 15 lakh gross, about Rs 7.09 lakh at Rs 20 lakh, and a constant Rs 8 lakh above roughly Rs 24 lakh, because both regimes tax the marginal rupee at 30% there.
- Marginal relief prevents the Rs 12 lakh rebate threshold from making you worse off in absolute terms, but income just above it is taxed heavily at the margin.
- The New Regime is the default; salaried filers without business income can choose afresh each year at filing.

Nothing changed in Budget 2026, so the FY 2026-27 decision comes down to the same arithmetic as last year. Below about Rs 12.75 lakh of gross salary the New Regime gives you zero tax and the question does not arise. Above it, you need Rs 5.44 lakh of deductions at Rs 15 lakh, about Rs 7.09 lakh at Rs 20 lakh, and a flat Rs 8 lakh once you clear roughly Rs 24 lakh.
Test yourself against that number honestly, using deductions you actually claim rather than ones you could theoretically assemble. For most salaried people without a substantial home loan, the total falls short — which is the real reason the New Regime has become the default answer, not a matter of preference. And because you can choose afresh at filing, there is no cost to computing both before you decide.
