Every April, millions of salaried Indians get a form from their HR department asking which tax regime they want. Most tick a box without calculating anything. Some copy a colleague's choice. Some stick with what they picked last year out of habit.

That one untested decision can easily cost ₹30,000 to ₹55,000 in avoidable tax — paid unnecessarily to the government when it could have stayed in your bank account.

The confusion is understandable. Since the new tax regime became the default from FY 2024-25, and Budget 2025 brought dramatic slab changes, many people are working with outdated information. The truth in FY 2025-26 is more decisive than most articles suggest: for a large majority of salaried Indians earning under ₹13 lakh, the new regime is unambiguously better. Above ₹15 lakh, individual deduction profiles matter enormously.

This guide uses verified FY 2025-26 numbers, three real salary examples at ₹6 lakh, ₹10 lakh, and ₹15 lakh, and a break-even analysis that tells you exactly when and whether the old regime makes sense for you.

What Budget 2025 Changed — The Three Numbers That Matter

Budget 2025 (announced February 1, 2025) made the most significant overhaul to the new regime since its launch. For salaried employees, three changes define FY 2025-26:

• Basic exemption raised to ₹4 lakh (was ₹3 lakh). Income below this is taxed at 0% under the new regime.
• Section 87A rebate increased to ₹60,000 for taxable incomes up to ₹12 lakh. This eliminates 100% of the tax liability — you pay nothing if your net taxable income is ₹12 lakh or less.
• Standard deduction raised to ₹75,000 for salaried individuals (was ₹50,000). Combined with the rebate, this creates a zero-tax window for salaried employees up to ₹12.75 lakh gross salary.
   

Tax Slabs Side by Side: FY 2025-26

New Tax Regime — Default from FY 2024-25

87A Rebate: Up to ₹60,000 if taxable income ≤ ₹12,00,000. Effectively makes tax = ₹0 for taxable income up to ₹12 lakh. Salaried standard deduction: ₹75,000. Cess: 4% on final tax.

Old Tax Regime — Optional (Below 60 Years)

87A Rebate: Up to ₹12,500 if taxable income ≤ ₹5,00,000. Salaried standard deduction: ₹50,000 (less than new regime). Deductions like 80C, HRA, home loan interest, 80D are available here.

What You Give Up in the New Regime

The new regime's lower rates come at a specific cost — most deductions and exemptions are unavailable. Here is the full picture:

Real Numbers: Three Salary Profiles Compared

All calculations below are for a salaried individual below 60 years, FY 2025-26 (AY 2026-27). Health and education cess at 4% is applied on all final tax figures. These are computed from verified slab rates — not estimates.

Scenario 1 — Gross Salary: ₹6,00,000 per year

Profile: Entry-level employee. Lives in own home (no HRA). PF deducted from salary (₹24,000/year counts as 80C). No home loan. Minimal investments.

Honest takeaway for ₹6L salary: You pay zero tax under both regimes — Section 87A covers you completely in both cases. So why prefer new regime? Because you don't need to force ₹50,000 into PF or any 80C investment just to reduce tax. The new regime gives you higher standard deduction (₹75,000 vs ₹50,000) and more flexibility with your money — without paperwork or investment commitments.

Scenario 2 — Gross Salary: ₹10,00,000 per year

Profile: Mid-level professional, pays rent in a metro city. Has PF, invests in health insurance. Old regime deductions: ₹50,000 standard + ₹1,20,000 HRA + ₹1,50,000 Section 80C + ₹25,000 Section 80D = ₹2,95,000 total.

Honest takeaway for ₹10L salary: This is the most important insight in this article. Even with ₹2.95 lakh in real deductions — HRA, full 80C, and health insurance — the old regime costs ₹55,640 more than new regime. The 87A rebate in the new regime is simply too powerful. At ₹10 lakh salary, the old regime almost cannot win regardless of your investments.

Scenario 3 — Gross Salary: ₹15,00,000 per year

Profile: Senior employee, has a home loan (₹2 lakh annual interest), maximised 80C, pays health insurance. Old regime deductions: ₹50,000 standard + ₹1,50,000 Section 80C + ₹2,00,000 home loan interest + ₹25,000 Section 80D = ₹4,25,000 total.

Honest takeaway for ₹15L salary: Even with ₹4.25 lakh in real deductions — home loan interest, full 80C, and health insurance — new regime still wins by ₹42,900. For old regime to beat new at ₹15 lakh, your total deductions need to exceed ₹5.75 lakh. That requires a large HRA claim on top of everything else — typically only possible for metro-based employees paying ₹25,000+ in rent per month with high salary HRA components.

Break-Even Guide: When Does Old Regime Actually Win?

The single most useful question to answer: at what deduction level does the old regime finally become cheaper? Here it is, by income level:

The pattern is clear: the 87A rebate in the new regime is decisive below ₹12.75 lakh taxable income. Above that, it disappears entirely, and the comparison becomes about whether your actual deductions can compensate for the old regime's higher slab rates.

Quick Decision Guide: Which Regime Suits You?

 Choose New Regime if any of these apply…

• Your gross salary is ₹12.75 lakh or below — you almost certainly pay zero tax.
• You are in the early stages of your career with minimal planned investments.
• You live in your own home (no HRA) and have no active home loan on a self-occupied property.
• You want simplicity — no investment proofs, no rent receipts, no annual 80C tracking.
• You earn between ₹10L–₹13L and do not have substantial HRA + home loan simultaneously.
• You prefer to invest freely without tax-forced commitments to PPF, ELSS, or LIC every year.

 Choose Old Regime if ALL of these apply together…

• You pay significant rent AND receive a high HRA component from your employer — typically ₹20,000+ per month in a metro.
• You have an active home loan with at least ₹1.5 lakh in annual interest on a self-occupied property.
• You have maximised Section 80C (₹1.5 lakh) AND pay health insurance for yourself and family (₹25,000+ under 80D).
• Your combined verified deductions cross the break-even threshold for your income level (see table above).
• You have calculated the actual numbers for your salary structure — not assuming based on general advice.

5 Mistakes Salaried Employees Make Every Year

How to Switch Regimes at ITR Filing — Step by Step

For salaried employees without business income, switching is straightforward and can be done at every filing:

1. Step 1: Collect your Form 16 from your employer. It shows your gross salary, TDS deducted, and any deductions already considered.
2. Step 2: Calculate your tax liability under both regimes using your actual income and eligible deductions. Use a verified tax calculator or ask your CA.
3. Step 3: Log in to the income tax e-filing portal at incometax.gov.in with your PAN.
4. Step 4: While filling your ITR form, select your preferred regime in the designated field. New regime is pre-selected by default — change it to old regime if your calculation shows it is better.
5. Step 5: No separate form is required for salaried taxpayers without business income. The selection in the ITR form is legally sufficient.
6. Step 6: If you declared a different regime to HR and excess TDS was deducted, the difference will be refunded by the Income Tax Department after filing. Refunds typically process within 4–8 weeks of ITR verification.

Frequently Asked Questions

Q: At ₹10 lakh salary, can the old regime ever be better?

Almost never in FY 2025-26. As shown in Scenario 2, even with ₹2.95 lakh in genuine deductions, the old regime costs ₹55,640 more. The Section 87A rebate in the new regime eliminates all tax when taxable income is ₹9.25 lakh (under ₹12 lakh threshold). For old regime to win at ₹10 lakh, you would need extraordinary deductions that are practically impossible for a typical salaried employee.
 

Q: Can I claim HRA in the new tax regime?

No. HRA exemption under Section 10(13A) is not available in the new regime. If you pay significant rent — especially in metros like Mumbai, Delhi, or Bengaluru — and receive a large HRA component in your salary, this is one of the strongest reasons to consider the old regime, but only alongside other deductions at higher salary levels.
 

Q: I declared new regime to HR but want to switch at ITR filing — can I?

Yes, for salaried employees without business income. Your declaration to HR only affects how TDS is deducted throughout the year. At ITR filing time, you can choose either regime regardless of what you told HR. If you switch to old regime at filing, any excess TDS will be refunded to your bank account.
 

Q: What is the Section 87A rebate and why does it matter so much?

Section 87A is a tax rebate that eliminates your entire income tax liability if your net taxable income falls below a threshold. In the new regime for FY 2025-26, this threshold is ₹12 lakh (with a maximum rebate of ₹60,000). In the old regime, the threshold is only ₹5 lakh. This difference is the single biggest reason why the new regime is better for most salaried Indians — it creates a massive zero-tax window that the old regime simply cannot match.
 

Q: Is EPF contribution deductible in the new regime?

No. Your own EPF contribution falls under Section 80C, which is not available in the new regime. However, your employer's EPF contribution is not taxable income and does not require a deduction claim — it remains unaffected. Only your own contribution becomes non-deductible when you choose new regime.
 

Q: Does the new regime offer any benefit for senior citizens?

Not particularly. The new regime applies the same slab rates to all age groups — unlike the old regime, which provides a higher basic exemption of ₹3 lakh for seniors (60–80 years) and ₹5 lakh for super seniors (above 80). Senior citizens with multiple deductions, or those with income mostly from FD interest, should compare both regimes carefully rather than defaulting to new regime.
 

Q: Can I claim home loan interest in the new regime?

Partially. Interest on a home loan for a self-occupied property (Section 24b, up to ₹2 lakh) is not claimable in the new regime. However, if the property is let out (rented to tenants), the actual interest paid can still be deducted from rental income in both regimes without any cap. This distinction matters for people who own and rent out a second property.
 

Q: What deductions are still allowed in the new regime?

The new regime allows very few deductions: standard deduction of ₹75,000 for salaried individuals, employer's NPS contribution under Section 80CCD(2), interest on home loan for let-out property, contributions to Agniveer Corpus Fund under Section 80CCH, and the standard deduction on family pension (lower of ₹25,000 or one-third of pension). That is substantially narrower than the old regime.
 

Q: If I choose old regime, can I change to new regime next year?

Yes, for salaried employees without business income — you can switch freely between regimes every financial year. Business income taxpayers face a different rule: they can switch from old to new only once, and revert only once in their lifetime. For most salaried employees, there is no permanent commitment to either regime.
 

Q: What documents do I need if I choose the old regime?

You will need: Form 16 from your employer, HRA rent receipts and landlord's PAN (if HRA exceeds ₹1 lakh per year), home loan interest certificate from your bank, investment proof for 80C instruments (PPF passbook, ELSS statements, LIC premium receipts, PF statement), health insurance premium receipt for 80D, and any other supporting documents for deductions claimed. The new regime requires none of these — just your Form 16.
 

The Bottom Line

The most important shift in FY 2025-26 is this: the new regime is no longer just simpler — it is genuinely cheaper for the vast majority of salaried Indians. The combination of lower slab rates, higher standard deduction (₹75,000 vs ₹50,000), and the powerful Section 87A rebate up to ₹12 lakh creates a situation where the old regime's deductions need to be very large — and very real — to overcome the mathematical advantage of the new regime.

Below ₹12.75 lakh gross salary: choose new regime unless a specific, verified calculation says otherwise.

Between ₹13 lakh and ₹20 lakh: calculate both regimes with your actual deductions. Do not assume either way. The answer depends on whether you have a home loan, meaningful HRA, and a disciplined 80C investment portfolio simultaneously.

Above ₹20 lakh: old regime can win — but only with a large, well-structured deduction portfolio. Worth calculating, but not worth assuming.
