# Old vs New Tax Regime in India (2026) - Which Should You Pick?
TL;DR: After Budget 2025, the new tax regime is the default and usually wins for salaried Indian taxpayers. Income up to ₹12.75 lakh is effectively tax-free. The old regime is still better only when your total deductions (80C, 80D, HRA, home loan interest) cross approximately ₹3.5-4 lakh, which typically happens at higher incomes with a home loan and significant rent.
Quick answer
- Default to new regime if your salary income is under ₹15 lakh and you do not claim large HRA or home loan interest.
- Choose old regime if you claim full ₹1.5 lakh 80C, significant HRA, AND ₹2 lakh home loan interest deduction.
- Run the math each year. Your salary, rent, and investments change; the optimal regime can flip.
- The break-even is around ₹15-17 lakh of taxable income for someone with full deductions.
- Use an app to compute both regimes side-by-side; manual calculation is error-prone.
Adoption context: Per the Income Tax Department's bulletins for AY 2024-25, the majority of salaried filers had already migrated to the new regime even before the Budget 2025 changes; the higher rebate threshold of ₹12 lakh and the standard deduction lift to ₹75,000 are expected to widen the gap further in AY 2026-27. The Central Board of Direct Taxes (CBDT) publishes the regime-wise filing breakdown in its annual Direct Tax Statistics handbook.
Who this guide is for
This guide is for salaried Indian taxpayers in FY 2025-26 (assessment year 2026-27) earning ₹5 lakh to ₹1 crore who want to choose between the old and new income tax regimes intelligently. It covers the slab structure, the deductions that survive in each regime, worked examples at multiple income levels, and the practical decision rules.
The guide is not tax advice - your specific situation depends on factors only a CA or qualified tax professional can fully assess. Use this guide to understand the framework, then validate with a professional for filings involving multiple income heads, foreign income, or capital gains complexity.
The 2026 tax slabs (FY 2025-26)
After Budget 2025 (announced February 1, 2025), the new regime slabs apply for FY 2025-26 (income earned between April 1, 2025 and March 31, 2026; filed in AY 2026-27).
New regime - FY 2025-26
| Income slab | 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% |
Plus standard deduction of ₹75,000 for salaried taxpayers, and a Section 87A rebate that makes total income up to ₹12 lakh effectively tax-free (₹12.75 lakh with standard deduction included).
Old regime - FY 2025-26
| Income slab | Tax rate |
|---|---|
| Up to ₹2.5 lakh | Nil |
| ₹2.5 lakh to ₹5 lakh | 5% |
| ₹5 lakh to ₹10 lakh | 20% |
| Above ₹10 lakh | 30% |
Plus standard deduction of ₹50,000 for salaried, and the full deduction stack (80C, 80D, 80E, HRA, home loan interest, NPS, etc.).
Both regimes attract Health and Education Cess of 4% on the calculated tax, plus surcharge at higher incomes (10% from ₹50 lakh, 15% from ₹1 crore, 25% above; the old regime's 37% surcharge on income above ₹5 crore was retained while the new regime caps surcharge at 25%).
What deductions survive under each regime
The most common confusion is about which deductions you keep when you choose the new regime. The short answer is: very few.
Available under both regimes
- Standard deduction (₹75,000 new, ₹50,000 old).
- Employer's contribution to NPS under Section 80CCD(2), up to 14% of basic salary for government employees and 10% for others.
- Family pension deduction.
- Disability and conveyance allowance for specified categories.
- Interest on home loan for a let-out property (Section 24(b)).
Available only under the old regime
- Section 80C (₹1.5 lakh): ELSS, PPF, EPF, life insurance premium, NPS, principal on home loan, tuition fees, etc.
- Section 80D (₹25,000 self / ₹50,000 senior citizen parent): health insurance premium.
- Section 80E: education loan interest (no upper limit on amount; only 8 years).
- Section 80G: donations to specified charities.
- HRA exemption (under Section 10(13A)) for rent-paying employees.
- Home loan interest deduction for self-occupied property (Section 24(b), up to ₹2 lakh).
- Leave Travel Allowance (LTA).
- Sections 80CCD(1B), 80TTA, 80TTB, and others.
Available only under the new regime
The new regime offers no unique deduction beyond what is in "both" above. It compensates for the lost deductions with materially lower slab rates and the enhanced rebate.
Worked examples
These examples assume a salaried taxpayer with standard deduction applied. Numbers are rounded for clarity; a real filing will differ by a few thousand rupees due to cess, surcharge, and deduction details.
Example 1: CTC ₹10 lakh, low deductions
Assume gross salary ₹10 lakh, no HRA claim, ₹1 lakh in 80C, ₹25,000 in 80D health insurance.
| New regime | Old regime | |
|---|---|---|
| Gross salary | ₹10,00,000 | ₹10,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| 80C | - | ₹1,00,000 |
| 80D | - | ₹25,000 |
| Taxable income | ₹9,25,000 | ₹8,25,000 |
| Tax (before cess) | ₹0 (rebate) | ₹77,500 |
| Cess 4% | ₹0 | ₹3,100 |
| Total tax | ₹0 | ₹80,600 |
Verdict: New regime saves ₹80,600. Clear winner.
Example 2: CTC ₹15 lakh, full deductions
Assume gross salary ₹15 lakh, paying rent ₹3 lakh/year in Bangalore (HRA exemption approximately ₹2.4 lakh), full ₹1.5 lakh 80C, ₹25,000 80D.
| New regime | Old regime | |
|---|---|---|
| Gross salary | ₹15,00,000 | ₹15,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| HRA exemption | - | ₹2,40,000 |
| 80C | - | ₹1,50,000 |
| 80D | - | ₹25,000 |
| Taxable income | ₹14,25,000 | ₹10,35,000 |
| Tax (before cess) | ₹95,000 | ₹1,17,000 |
| Cess 4% | ₹3,800 | ₹4,680 |
| Total tax | ₹98,800 | ₹1,21,680 |
Verdict: New regime saves ₹22,880. New wins despite full old-regime deductions.
Example 3: CTC ₹25 lakh, full deductions + home loan
Assume gross salary ₹25 lakh, HRA exempt ₹2.4 lakh, ₹1.5 lakh 80C, ₹25,000 80D, ₹2 lakh home loan interest on self-occupied property.
| New regime | Old regime | |
|---|---|---|
| Gross salary | ₹25,00,000 | ₹25,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| HRA exemption | - | ₹2,40,000 |
| 80C | - | ₹1,50,000 |
| 80D | - | ₹25,000 |
| Home loan interest | - | ₹2,00,000 |
| Taxable income | ₹24,25,000 | ₹18,35,000 |
| Tax (before cess) | ₹3,46,250 | ₹3,67,500 |
| Cess 4% | ₹13,850 | ₹14,700 |
| Total tax | ₹3,60,100 | ₹3,82,200 |
Verdict: New regime saves ₹22,100. New wins narrowly even with full old-regime stack.
Example 4: CTC ₹50 lakh, full deductions + home loan
| New regime | Old regime | |
|---|---|---|
| Gross salary | ₹50,00,000 | ₹50,00,000 |
| Standard deduction | ₹75,000 | ₹50,000 |
| HRA exemption | - | ₹2,40,000 |
| 80C | - | ₹1,50,000 |
| 80D | - | ₹25,000 |
| Home loan interest | - | ₹2,00,000 |
| Taxable income | ₹49,25,000 | ₹43,35,000 |
| Tax (before cess + surcharge) | ₹11,02,500 | ₹11,17,500 |
| Cess + surcharge approximation | ~₹44,100 | ~₹44,700 |
| Total tax | ~₹11,46,600 | ~₹11,62,200 |
Verdict: Roughly equal; new wins by a small margin. Surcharge calculations differ slightly, and an aggressive tax planner with NPS additional 80CCD(1B) could tilt old regime favorably here.
Example 5: CTC ₹75 lakh, full deductions
At this income, the 10% surcharge applies and the calculation gets more involved. The new regime typically wins by ₹50,000 to ₹1,50,000 because the slab structure rewards higher income, and most old-regime deductions become marginal as a percentage of total income.
The decision rules
After the Budget 2025 changes, the practical decision tree is shorter than it used to be.
- Income under ₹12.75 lakh (after standard deduction): new regime almost always wins because of the 87A rebate that zeroes out the tax.
- Income ₹12.75 lakh to ₹17 lakh with no significant deductions: new regime wins by ₹20,000 to ₹50,000.
- Income ₹12.75 lakh to ₹17 lakh with full deductions including HRA: old regime can win by ₹10,000 to ₹30,000.
- Income above ₹17 lakh: new regime wins in almost all configurations.
- Income above ₹50 lakh: new regime wins by even more, because the surcharge cap is lower under the new regime.
The simple rule: unless you are renting in a Tier-1 city, have a self-occupied home loan, AND max out 80C/80D, the new regime is almost certainly your choice.
Common pitfalls
- Declaring one regime to your employer and switching at filing. Legal for salaried taxpayers, but if your employer deducted TDS under the old regime and you switch to new at filing, you may face a refund delay or a tax-payable shortfall plus interest.
- Forgetting Section 87A applies to total income, not after standard deduction. The ₹12 lakh threshold is total income after deductions; with the ₹75,000 standard deduction, the effective gross salary cap is ₹12.75 lakh. Earning ₹13 lakh and assuming zero tax under the new regime is wrong.
- Counting employer's PF as your own 80C. Employer's PF contribution is not your 80C. Only your own EPF contribution + voluntary contributions count toward the ₹1.5 lakh limit.
- Mixing rent paid to parents with HRA without rent receipts. Paying rent to parents is allowed and HRA-eligible, but you need a rent agreement, rent receipts, and your parent must declare the rent as income. The IT Department flags HRA claims without proper documentation.
- Ignoring NPS Section 80CCD(1B) extra ₹50,000. This ₹50,000 deduction is over and above the ₹1.5 lakh 80C limit and is available only under the old regime. It is the highest-leverage tax-saving move not already in your 80C if you are on the old regime.
- Choosing a regime based on a friend's situation. Tax outcomes depend on your specific income, rent, deductions, and assets. Always run your own numbers.
FAQ
Which tax regime is better in 2026?
For salaried taxpayers with low deductions, the new regime is almost always better. For taxpayers with high deductions - full ₹1.5 lakh 80C plus significant HRA plus ₹2 lakh home loan interest - the old regime can still beat the new until taxable income of about ₹15-17 lakh.
What changed in the new tax regime under Budget 2025?
Income up to ₹12 lakh became tax-free under the new regime via an enhanced Section 87A rebate. With ₹75,000 standard deduction, salaried earning up to ₹12.75 lakh effectively pay zero income tax.
Can I switch between regimes every year?
Salaried taxpayers can switch every financial year. Business or professional income switches are restricted to one re-entry into the new regime.
What deductions are available in the new regime?
Standard deduction (₹75,000), employer's NPS Section 80CCD(2), let-out property home loan interest, family pension, certain disability allowances. Most other popular deductions are not available.
Is HRA available in the new regime?
No. HRA exemption is old-regime only.
How does 80C work?
₹1.5 lakh deduction on specified investments (ELSS, PPF, EPF, etc.). At 30% bracket, saves ₹46,800. Only available under old regime.
What is the breakeven income?
With full deductions stack, around ₹15-17 lakh of taxable income. Below this, old wins; above, new wins.
Should I tell my employer my choice?
Yes, at the start of FY for TDS. Not binding at filing - you can switch.
How Qubera fits
Choosing between old and new regimes correctly each year requires running the numbers with your actual salary, rent, 80C investments, home loan interest, and any other deductions. The math is mechanical but unforgiving - a single missed deduction can flip the answer.
Qubera computes both regimes side-by-side from your linked accounts and salary inputs, shows which is better for your current year, and tells you what change in deductions would flip the outcome. The Ask interface answers questions like "if I top up my NPS by ₹50,000 under 80CCD(1B), does the old regime become better for me?" with a specific answer for your numbers.
Qubera does not file your return; for filing, ClearTax remains the workhorse, and for complex situations a CA is irreplaceable. Qubera handles the year-round optimization - the deductions to claim, the investments to make, the regime to declare to your employer - so that filing season is a confirmation, not a discovery. Download Qubera and link one salary credit; the regime recommendation is one of the first answers the app surfaces.
