Deep Dive

Old Tax Regime

The old tax regime — also called the existing or regular regime — has been the default income tax structure in India for decades. Its defining feature is the availability of over 70 exemptions and deductions that can significantly reduce taxable income. The most impactful are Section 80C (up to ₹1.5 lakh: EPF, PPF, ELSS, LIC, home loan principal, tuition fees), Section 80D (health insurance premium up to ₹25,000 self + ₹25,000 parents, or ₹50,000 if parents are senior citizens), HRA exemption (up to 50% of basic for metro residents), and Section 24(b) home loan interest (up to ₹2 lakh for self-occupied property).

The old regime rewards disciplined financial behaviour: investing in EPF/PPF/ELSS, taking health insurance, and owning a home with a loan all reduce your tax bill. For a salaried employee in the 30% slab who claims the full 80C (₹1.5L), 80D (₹25K), HRA (₹1.5L), home loan interest (₹2L), and standard deduction (₹50K), total deductions can reach ₹5.75 lakh — saving ~₹1.72 lakh in tax at the 30% rate.

The downside of the old regime is complexity: you need to maintain investment proofs, submit declarations to your employer, and ensure all deductions are correctly claimed. Missing even one investment certificate can result in excess TDS deduction. The system also creates implicit pressure to invest in specific products to save tax, which may not always align with the best financial decision.

New Tax Regime

The new tax regime, introduced in Budget 2020 and overhauled significantly in Budget 2023 and 2024, offers lower slab rates in exchange for removing most exemptions and deductions. The key improvements in Budget 2024 (effective FY 2024-25 and 2025-26): the standard deduction was raised to ₹75,000; the Section 87A rebate was extended to cover taxable income up to ₹7 lakh (making the effective zero-tax threshold ₹7.75 lakh gross for salaried employees); and the new regime was made the default for all individual taxpayers.

The new regime's slab structure is significantly more granular — six slabs vs three in the old regime — with lower rates at every band except the top 30% slab (which kicks in at ₹15L vs ₹10L in the old regime). For taxpayers with income between ₹10L and ₹15L, the new regime's 15% and 20% rates are dramatically lower than the old regime's 20% and 30% rates on the same income bands, making the new regime attractive even with moderate deductions.

The new regime also simplifies payroll: employees don't need to submit investment proofs, employers don't need to process exemption calculations, and tax filing is simpler. The employer's NPS contribution (Section 80CCD(2)) is still deductible — a significant benefit for those whose employer pays NPS. The regime is designed to favour taxpayers who invest in market instruments not linked to tax breaks, giving them the same after-tax outcome without forcing specific investment products.

Real-World Patterns

Salaried Employee, ₹10L CTC, Moderate Deductions

A salaried employee with ₹10 lakh CTC investing ₹1.5L in 80C, paying ₹20,000 in health insurance (80D), and receiving ₹1.2L HRA in a metro (50% of basic): Old regime taxable income ≈ ₹6.8L → tax ≈ ₹45,500. New regime taxable income = ₹10L − ₹75K = ₹9.25L → tax ≈ ₹42,500. Here, new regime wins marginally even with meaningful deductions. But add a home loan interest deduction of ₹2L: old regime taxable ≈ ₹4.8L → tax ≈ ₹17,000. Old regime wins decisively once home loan interest is in play.

First-Job Earner Under ₹7.75L — New Regime Always Wins

A fresher earning ₹6–7 lakh CTC who hasn't built investment habits pays zero tax under the new regime (up to ₹7.75L after standard deduction and 87A rebate). Even if they invest ₹50,000 in 80C, their old-regime tax saving is ~₹2,500 (5% of ₹50K) — the new regime's zero-tax threshold still wins. For incomes up to ₹7.75L, the new regime is almost always better regardless of deductions, because the effective tax savings from deductions in the 5% slab don't match the new regime's zero-tax benefit.

High Earner ₹25L+: Deduction-Heavy Old Regime Can Win

For a senior employee earning ₹25 lakh with a full deduction stack — ₹1.5L 80C, ₹25K 80D, ₹2L home loan interest, ₹1.5L HRA in metro, ₹50K standard deduction — total deductions: ₹5.75L. Old regime taxable: ₹19.25L → tax ≈ ₹4.55L. New regime taxable: ₹24.25L → tax ≈ ₹5.18L. Old regime saves ~₹63,000. As income grows into ₹30L+, the savings from old regime vs new regime on equivalent deductions tend to grow, because more income sits in the 30% slab where deductions provide 30 paise per rupee of savings.

Very High Income ₹5Cr+: New Regime Wins on Surcharge

For ultra-high earners above ₹5 crore, the new tax regime has a structural advantage: the maximum surcharge is capped at 25%, whereas the old regime can impose a 37% surcharge on income above ₹5 crore. This surcharge difference effectively makes the marginal rate 42.74% (30% + 37% surcharge + 4% cess) in the old regime vs 39% in the new regime for this income band. Even if the old regime offers significant deductions, the surcharge cap on the new regime can produce lower total tax. High-net-worth individuals should model both regimes including surcharge and cess before deciding.

Which should you choose?

New Regime is the right default for most taxpayers earning under ₹7.75 lakh (zero tax), and for those with minimal deductions under ₹2.5 lakh. Its simplicity and lower rates at mid-income bands make it attractive even at ₹10–15 lakh for taxpayers who don't maximise the old regime's deduction stack.

Old Regime wins for taxpayers who actively claim 80C, HRA, home loan interest, and 80D — especially in the 30% slab where each rupee of deduction saves 30 paise in tax. Run both regimes with your exact numbers using the income tax calculator before deciding — the answer is always personal.

Frequently Asked Questions

Which tax regime is better — old or new for FY 2025-26?

It depends on your total deductions. The new regime is better if your total deductions (80C + 80D + HRA + home loan interest + others) are below approximately ₹3.75 lakh (for incomes around ₹10–15 lakh). The old regime is better if your deductions exceed this threshold. For incomes below ₹7.75 lakh with no significant deductions, the new regime gives zero tax (₹7L rebate + ₹75K standard deduction). Use the income tax calculator to compare both regimes with your exact numbers.

What is the standard deduction in the new tax regime for FY 2025-26?

The standard deduction in the new tax regime is ₹75,000 per year for FY 2025-26 (increased from ₹50,000 in Budget 2024). In the old regime, the standard deduction remains ₹50,000. The higher standard deduction in the new regime means that salaried employees with gross income up to ₹7.75 lakh pay zero tax under the new regime (₹75,000 deduction + ₹7 lakh Section 87A rebate covers the entire income).

Can I claim 80C deductions in the new tax regime?

No. Section 80C deductions (PPF, ELSS, EPF contribution, LIC premium, home loan principal, tuition fees, NSC, etc.) are not available under the new tax regime. The new regime gives lower slab rates in exchange for removing most deductions. The only major deductions still allowed in the new regime are: standard deduction (₹75,000), employer NPS contribution (Section 80CCD(2)), and Agniveer corpus fund deduction.

What are the new tax regime slabs for FY 2025-26?

New Tax Regime slabs for FY 2025-26: ₹0–₹3 lakh: Nil; ₹3–₹7 lakh: 5%; ₹7–₹10 lakh: 10%; ₹10–₹12 lakh: 15%; ₹12–₹15 lakh: 20%; Above ₹15 lakh: 30%. Section 87A rebate makes tax zero for income up to ₹7 lakh. Standard deduction of ₹75,000 means effective zero tax up to ₹7.75 lakh gross income. Surcharge applies at 10% for income ₹50L–₹1Cr, 15% for ₹1Cr–₹2Cr, 25% for ₹2Cr–₹5Cr, and 25% above ₹5Cr (reduced from 37% in new regime).

Can I claim HRA in the new tax regime?

No. House Rent Allowance (HRA) exemption is not available under the new tax regime. If you are paying significant rent — especially in metro cities where HRA exemptions can be ₹1.5–₹3 lakh per year — the old regime may save you more tax. HRA exemption is calculated as the minimum of: (1) actual HRA received, (2) 50% of basic+DA (metro) or 40% (non-metro), (3) actual rent paid minus 10% of basic+DA. Calculate your HRA exemption before switching to the new regime.

Is the new tax regime the default from FY 2024-25?

Yes. From FY 2023-24 onwards, the new tax regime is the default regime for individual taxpayers. If you do not specifically opt for the old regime, the new regime will be applied automatically. Salaried employees must inform their employer which regime they choose at the start of the financial year. If you miss declaring and your employer deducts TDS under the new regime, you can still switch to the old regime when filing your ITR (for salaried taxpayers — those with business income have fewer switching opportunities).

At what income does the old regime become better than the new regime?

There is no single income threshold — it depends on your deductions. However, as a general guide: for incomes of ₹10 lakh, the old regime becomes better once your total deductions exceed approximately ₹2.5–3 lakh (80C + 80D + HRA + home loan interest combined). For ₹15 lakh income, the threshold rises to approximately ₹3.75–4 lakh in deductions. For ₹20 lakh+, significant deductions (₹5 lakh+) are needed for the old regime to win. Use an income tax calculator with both regimes and your actual deductions to find your personal break-even.

Can I switch between old and new tax regime every year?

Salaried employees (no business income) can switch between old and new regime every year at the time of filing their ITR. You can inform your employer of your preferred regime for TDS deduction each year, and then choose differently when filing if your situation changes. Taxpayers with business or professional income (presumptive or regular) face a stricter rule: they can switch from new to old regime only once in their lifetime, and switching back from old to new is also once only. If you have business income, the switch is a more permanent decision.
