Old vs New Tax Regime: Which Saves You More? (FY 2026-27)

For most salaried people in FY 2026-27, the new tax regime saves more money — but that answer flips the moment your legitimate deductions cross a tipping point. This article shows you exactly where that tipping point sits, with real rupee arithmetic, so you can make the call in under ten minutes.

The Two Regimes at a Glance

India now runs two parallel income-tax systems. The old regime has higher slab rates but lets you claim dozens of deductions and exemptions — HRA, LTA, 80C investments, home loan interest, NPS contributions, and more. The new regime (the default from FY 2024-25 onwards) offers lower slab rates but strips away most of those deductions.

Two extra points matter here. First, salaried taxpayers in the new regime get a standard deduction of ₹75,000. Second, the Section 87A rebate in the new regime makes total tax zero for net taxable income up to ₹12,00,000 (after the standard deduction). In the old regime the 87A rebate threshold is ₹5,00,000.

Worked Example 1 — ₹10,00,000 Salary (Modest Deductions)

Ravi is a software engineer with a gross salary of ₹10,00,000. He invests ₹1,00,000 in 80C instruments and pays HRA that gives him a ₹60,000 exemption. That is ₹1,60,000 in deductions plus the old-regime standard deduction of ₹50,000 — total ₹2,10,000.

• Old regime taxable income: ₹10,00,000 − ₹2,10,000 = ₹7,90,000
• Tax on ₹7,90,000 (old slabs): ₹12,500 (on first ₹5L at 5%) + ₹58,000 (₹2,90,000 at 20%) = ₹70,500 + 4% cess = ₹73,320
• New regime taxable income: ₹10,00,000 − ₹75,000 (standard deduction) = ₹9,25,000
• Tax on ₹9,25,000 (new slabs): ₹20,000 (5% on ₹4L) + ₹22,500 (10% on ₹2,25,000) = ₹42,500 + 4% cess = ₹44,200

Verdict: New regime saves Ravi ₹29,120 this year.

Worked Example 2 — ₹15,00,000 Salary (Heavy Deductions)

Priya earns ₹15,00,000. She has a home loan (₹2,00,000 interest under Section 24b), 80C investments of ₹1,50,000, NPS contribution under 80CCD(1B) of ₹50,000, and HRA exemption of ₹1,20,000. Total deductions plus old-regime standard deduction: ₹50,000 + ₹2,00,000 + ₹1,50,000 + ₹50,000 + ₹1,20,000 = ₹5,70,000.

• Old regime taxable income: ₹15,00,000 − ₹5,70,000 = ₹9,30,000
• Tax: ₹12,500 + ₹86,000 (20% on ₹4,30,000) = ₹98,500 + 4% cess = ₹1,02,440
• New regime taxable income: ₹15,00,000 − ₹75,000 = ₹14,25,000
• Tax: ₹20,000 + ₹30,000 (10% on ₹3L) + ₹45,000 (15% on ₹3L) + ₹45,000 (20% on ₹2,25,000) = ₹1,40,000 + 4% cess = ₹1,45,600

Verdict: Old regime saves Priya ₹43,160. Heavy deductions change everything.

The Tipping-Point Rule of Thumb

There is no single magic number, but a practical guide: if your total deductions and exemptions (everything — 80C, HRA, home loan, NPS, 80D, LTA, standard deduction difference) exceed roughly ₹3.75 lakh at a ₹15 lakh salary level, the old regime usually wins. At lower incomes the threshold is smaller. Rather than estimating, plug your actual numbers into KyaTax's Regime Calculator for a precise comparison in seconds.

Deductions That Only the Old Regime Allows

• Section 80C — up to ₹1,50,000 (PPF, ELSS, life insurance premiums, EPF, tuition fees)
• Section 24(b) — up to ₹2,00,000 home loan interest on a self-occupied property
• HRA exemption — calculated under Section 10(13A); can be substantial for metro residents
• Section 80D — health insurance premiums for self and parents
• Section 80CCD(1B) — additional NPS contribution up to ₹50,000
• LTA — Leave Travel Allowance exemption for domestic travel
• Professional tax deduction under Section 16

The new regime retains only a handful of exemptions: the ₹75,000 standard deduction for salaried individuals, employer NPS contributions under Section 80CCD(2), and a few others. It does not allow 80C, 80D, HRA, or home loan interest deduction on self-occupied property.

Who Should Seriously Consider the Old Regime?

1. Salaried people paying rent in metro cities with high HRA exemptions
2. Anyone with an active home loan on a self-occupied property
3. Those maximising 80C + 80CCD(1B) + 80D together — that alone is ₹3,50,000 in potential deductions
4. Small-business owners with legitimate professional expenses and higher net incomes

Common Mistakes People Make When Choosing a Regime

• Forgetting the employer NPS deduction works in the new regime too. Section 80CCD(2) — employer's contribution to NPS — is allowed in the new regime. Many employees don't ask their HR to route a portion of salary through NPS, leaving free tax savings on the table.
• Comparing gross salary, not taxable income. The regime comparison only makes sense after applying the correct standard deduction for each regime (₹50,000 old, ₹75,000 new for FY 2026-27). People who skip this step often calculate incorrectly.
• Assuming the old regime always wins at high incomes. At ₹20 lakh+ with no home loan and no HRA, the new regime's lower mid-range slab rates often still come out ahead. Check with actual numbers.
• Missing the declaration deadline with the employer. If you want the old regime, you must submit Form 10IEA (for business income) or inform your employer before the first salary of the financial year. Waiting until March means excess TDS has already been deducted at new-regime rates.
• Thinking the switch is permanent for salaried employees. Salaried individuals with only salary and investment income can switch regimes every single year at the time of filing their ITR. The restriction applies mainly to taxpayers with business or professional income.

Frequently asked questions

Is the new tax regime compulsory from FY 2026-27?

No. The new regime is the default, meaning your employer will apply it if you don't specify otherwise. But salaried individuals can still opt for the old regime by informing their employer at the start of the year or by choosing it when filing their ITR. It is not compulsory.

Can I switch between old and new regime every year?

Yes, if your income is from salary and other non-business sources. You can make a fresh choice each financial year. Taxpayers who have business or professional income face a restriction: once they opt out of the new regime, they can only return to it once in their lifetime.

Does the ₹12 lakh tax-free limit apply in the old regime too?

No. The Section 87A rebate that makes tax zero up to ₹12,00,000 of net taxable income applies only under the new regime for FY 2026-27. Under the old regime, the 87A rebate applies only if net taxable income does not exceed ₹5,00,000.

Which regime is better for a salaried person earning ₹8,00,000 with no major deductions?

The new regime is almost certainly better in this case. After the ₹75,000 standard deduction, taxable income falls to ₹7,25,000. Tax works out to around ₹37,500 before cess. In the old regime without significant deductions, you would pay more. If you have at least ₹1,50,000 in 80C and some HRA, run the numbers — but even then the new regime is likely cheaper at this income level.
