Every salaried employee in India faces the same annual puzzle: old vs new tax regime for salaried employees 2026 — which one leaves more money in your pocket? For FY 2026-27 (assessment year 2027-28), the rules are now stable: Budget 2026 left the slabs, the Rs 12 lakh rebate and the Rs 75,000 standard deduction untouched. But stability does not mean the choice is obvious. In this guide, we lay out both regimes side by side and run the complete break-even math at a Rs 15 lakh salary, so you can make the decision with real numbers instead of guesswork.
Old vs New Tax Regime: The FY 2026-27 Slabs Compared
Let us start with the facts. The new regime is the default — if you do nothing, you are taxed under it. The old regime must be actively chosen every year (salaried employees without business income can switch annually).
New regime slabs (FY 2026-27): income up to Rs 4 lakh is tax-free; Rs 4-8 lakh is taxed at 5%; Rs 8-12 lakh at 10%; Rs 12-16 lakh at 15%; Rs 16-20 lakh at 20%; Rs 20-24 lakh at 25%; and above Rs 24 lakh at 30%. Salaried employees get a standard deduction of Rs 75,000, and the Section 87A rebate of up to Rs 60,000 makes taxable income up to Rs 12 lakh effectively tax-free — meaning a gross salary of up to Rs 12.75 lakh carries zero tax.
Old regime slabs (FY 2026-27): income up to Rs 2.5 lakh is tax-free; Rs 2.5-5 lakh at 5%; Rs 5-10 lakh at 20%; and above Rs 10 lakh at 30%. The standard deduction is Rs 50,000, and the 87A rebate of up to Rs 12,500 makes taxable income up to Rs 5 lakh tax-free. The old regime keeps nearly all deductions: 80C (Rs 1.5 lakh), 80D (health insurance), HRA, home loan interest (Rs 2 lakh on self-occupied property), NPS (extra Rs 50,000 under 80CCD(1B)), and more.
- New regime: lower rates, Rs 75,000 standard deduction, almost no other deductions
- Old regime: higher rates, Rs 50,000 standard deduction, full deduction menu
- Both: 4% health and education cess on the computed tax; surcharge only at very high incomes
Full Tax Math at Rs 15 Lakh Salary (FY 2026-27)
Now the numbers that matter for the old vs new tax regime decision. Take a salaried employee earning Rs 15,00,000 per year.
New regime calculation: Start with Rs 15,00,000, subtract the Rs 75,000 standard deduction, giving taxable income of Rs 14,25,000. Tax is computed slab by slab: 5% on Rs 4-8 lakh = Rs 20,000; 10% on Rs 8-12 lakh = Rs 40,000; 15% on Rs 12-14.25 lakh = Rs 33,750. Total tax = Rs 93,750, plus 4% cess = Rs 97,500. Simple, no deductions needed.
Old regime, Scenario A — modest deductions: Suppose you claim 80C of Rs 1.5 lakh (PPF, ELSS or EPF — see our PPF vs ELSS comparison for salaried employees), health insurance of Rs 25,000 under 80D, and NPS of Rs 50,000. Total deductions beyond the standard deduction = Rs 2,25,000. Taxable income = Rs 15,00,000 – Rs 50,000 – Rs 2,25,000 = Rs 12,25,000. Tax: 5% on Rs 2.5-5 lakh = Rs 12,500; 20% on Rs 5-10 lakh = Rs 1,00,000; 30% on Rs 10-12.25 lakh = Rs 67,500. Total = Rs 1,80,000, plus 4% cess = Rs 1,87,200.
Result: with ordinary deductions, the new regime wins by Rs 89,700 at a Rs 15 lakh salary. That is not a small difference — it is nearly 6% of your salary.
Old regime, Scenario B — heavy deductions: Now add HRA of Rs 2,40,000 and home loan interest of Rs 2,00,000 to the Rs 2,25,000 above. Total deductions beyond standard = Rs 6,65,000. Taxable income = Rs 15,00,000 – Rs 50,000 – Rs 6,65,000 = Rs 7,85,000. Tax: 5% on Rs 2.5-5 lakh = Rs 12,500; 20% on Rs 5-7.85 lakh = Rs 57,000. Total = Rs 69,500, plus 4% cess = Rs 72,280. Now the old regime wins by about Rs 25,000.
The Break-Even Point: When Does the Old Regime Win?
The two scenarios above reveal the real rule of the old vs new tax regime choice. At a Rs 15 lakh salary, the old regime needs total deductions (beyond the Rs 50,000 standard deduction) of roughly Rs 5,12,500 just to match the new regime’s Rs 97,500 tax bill. Anything above that, and the old regime pulls ahead; anything below, and the new regime wins.
In practice, reaching Rs 5.12 lakh of deductions almost always requires a combination of HRA and home loan interest — the two big-ticket deductions. A typical winning combination looks like this:
- HRA exemption: Rs 2,00,000 – 2,50,000 (metro renters)
- Section 80C: Rs 1,50,000 (EPF, PPF, ELSS, children’s tuition)
- Home loan interest: up to Rs 2,00,000 (self-occupied)
- 80D health insurance: Rs 25,000 – 50,000
- NPS additional: Rs 50,000
If you are a renter paying significant rent AND servicing a home loan (yes, both can coexist — you can live in a rented house in one city while owning in another), the old regime is usually your winner. If you live in your own fully-paid home, or with family, and your only deductions are 80C and 80D, the new regime wins comfortably at Rs 15 lakh.
One more thing to check before deciding: do not invest just to save tax. If you are putting money into products you do not need purely to claim 80C, you are spending Rs 1.5 lakh to save maybe Rs 45,000. Our guide on the best way to invest Rs 10,000 per month shows how to build a monthly plan that works regardless of the regime you pick.
Marginal Relief: The Rs 12 Lakh Cliff Edge
One feature of the new regime deserves its own explanation: marginal relief. Under the new regime, income up to Rs 12 lakh is fully tax-free thanks to the Rs 60,000 rebate. Without any protection, someone earning Rs 12,00,100 would suddenly owe the full slab tax — a brutal cliff edge.
Marginal relief fixes this: just above the Rs 12 lakh threshold, your extra tax can never exceed the extra income you earned. So if your taxable income is Rs 12,50,000, you do not pay the full slab tax of about Rs 67,500 — you pay only a small, proportionate amount. This keeps the transition smooth and is one more reason the new regime is friendlier than it looks for incomes in the Rs 12-14 lakh zone.
Finally, avoid the three mistakes salaried employees make most often. First, choosing a regime in April based on last year’s salary and never revisiting it — a raise, a new rental, or a home loan can flip the answer mid-year. Second, double-counting: the employer’s EPF contribution and your standard deduction are handled automatically, so do not add them again when totalling deductions. Third, forgetting that the Rs 75,000 standard deduction in the new regime already covers what the Rs 50,000 standard deduction does in the old — compare net taxable incomes, not gross salaries, when you run your own math.
Old vs New Tax Regime: Quick Decision Rule for Salaried Employees
Use this simple test to settle the old vs new tax regime question: add up your realistic deductions beyond the standard deduction — 80C, 80D, HRA, home loan interest, NPS. If the total is comfortably above Rs 5 lakh (at a Rs 15 lakh salary; the threshold rises with income), run the exact numbers for the old regime — it probably wins. If it is below Rs 4 lakh, the new regime almost certainly wins and you can stop doing 80C paperwork entirely.
Remember three practical points. First, salaried employees without business income can redo the old vs new tax regime comparison every year, so you are not locked in — re-evaluate each April. Second, if you are in the new regime, stop buying tax-saving products for tax reasons; buy investments for returns instead. Third, tax slabs and rebates can change in any Budget, so re-check the rules each February before finalising your choice.

Frequently Asked Questions
At what salary does the old regime beat the new regime?
It depends on deductions, not salary alone. At a Rs 15 lakh salary you need roughly Rs 5.12 lakh of deductions beyond the standard deduction for the old regime to win — which usually requires HRA plus home loan interest combined.
Can salaried employees switch tax regimes every year?
Yes, if you have no business or professional income. Salaried employees can choose between the regimes every financial year when filing returns.
What is marginal relief in the new tax regime?
Just above the Rs 12 lakh taxable-income threshold, marginal relief ensures your extra tax never exceeds the extra income you earned — smoothing the cliff edge where the 87A rebate ends.
Is the new tax regime the default option?
Yes. The new regime has been the default since FY 2023-24. If you want the old regime, you must actively opt for it while filing.
