Old vs New Tax Regime 2026: Which Should You Choose?

Last updated: May 2026. General information, not tax advice. Slabs reflect FY 2026-27 (Budget 2026 retained FY 2025-26 structure — no slab changes).

Quick answer: The new tax regime is the default and is better for most salaried people who don’t claim large deductions — income up to ₹12 lakh is effectively tax-free (₹12.75 lakh for salaried after the ₹75,000 standard deduction) via the Section 87A rebate. The old regime wins only if your total deductions (80C + 80D + HRA + home loan interest + NPS, etc.) are large enough to push your old-regime tax below your new-regime tax. The only reliable way to decide is to compute both — but the breakeven is high, so most people are better off on the new regime.

Every January your employer asks you to declare a tax regime, and every July you can still switch when filing your ITR. Most people pick on vibes. Here’s how to actually decide.

The two regimes in one paragraph

The new regime offers lower slab rates and a big rebate, but disallows most deductions/exemptions (no 80C, no HRA, no home-loan interest under the usual sections — with a few exceptions like the standard deduction and employer NPS). The old regime has higher slab rates but lets you claim the full menu of deductions and exemptions. New regime = simplicity + low rates, few deductions. Old regime = higher rates, but you can shrink taxable income with deductions.

New tax regime — slabs (FY 2026-27)

Income slab	Rate
Up to ₹4,00,000	Nil
₹4,00,001 – ₹8,00,000	5%
₹8,00,001 – ₹12,00,000	10%
₹12,00,001 – ₹16,00,000	15%
₹16,00,001 – ₹20,00,000	20%
₹20,00,001 – ₹24,00,000	25%
Above ₹24,00,000	30%

Plus, under the new regime:

• Standard deduction: ₹75,000 for salaried
• Section 87A rebate makes tax zero for taxable income up to ₹12 lakh (rebate up to ₹60,000) — so a salaried person with gross income up to ₹12.75 lakh can pay zero tax after the standard deduction, subject to conditions
• Employer NPS contribution deductible under 80CCD(2) up to 14% of basic (a rare deduction the new regime still allows)
• 4% health & education cess applies; surcharge at higher incomes (capped at 25% in new regime)

The rebate does not apply to special-rate income (e.g., capital gains under 111A/112A). NRIs cannot claim the 87A rebate.

Old tax regime — slabs

Income slab	Rate
Up to ₹2,50,000	Nil
₹2,50,001 – ₹5,00,000	5%
₹5,00,001 – ₹10,00,000	20%
Above ₹10,00,000	30%

Plus, under the old regime:

• Standard deduction: ₹50,000 for salaried
• Section 87A rebate makes tax zero for taxable income up to ₹5 lakh
• Full deductions available: 80C (₹1.5L), 80D (health insurance), 80CCD(1B) (₹50K extra NPS), HRA exemption, home loan interest (Sec 24b, up to ₹2L self-occupied), LTA, and more
• Senior citizens get higher basic exemption limits

The decision rule

The new regime wins unless your deductions are large enough that the old regime’s higher rates still produce lower tax. Practically, the more of these you genuinely have, the more the old regime is worth checking:

• Full 80C (₹1.5L: EPF, ELSS, PPF, life insurance, principal repayment, etc.)
• 80D health insurance premiums
• 80CCD(1B) ₹50K extra NPS
• Significant HRA exemption (high rent, you don’t own where you live)
• Home loan interest (up to ₹2L self-occupied under Sec 24b)

A common heuristic: if your total deductions+exemptions exceed roughly ₹4–5 lakh+ and your income is in the mid range, the old regime may win. Below that, the new regime almost always wins. But heuristics aren’t a substitute for the actual calculation — the breakeven shifts with income level.

Worked comparison (illustrative)

Person A: ₹15 LPA, minimal deductions (only EPF ~₹50K)

• New regime: taxable ₹14.25L after standard deduction → tax ≈ ₹1.49L + cess ≈ ₹1.55L
• Old regime: even with ₹50K 80C, taxable ~₹13.5L → tax ≈ ₹2.1L+
• New regime wins clearly.

Person B: ₹15 LPA, heavy deductions (₹1.5L 80C + ₹50K NPS + ₹25K 80D + ₹2L home loan interest + ₹1.8L HRA ≈ ₹6L deductions)

• Old regime: taxable ≈ ₹9L → tax materially lower
• New regime: taxable ₹14.25L → higher tax
• Old regime can win for this profile.

Same salary, opposite answer — entirely because of deductions. This is why you must compute both.

How and when to choose / switch

• The new regime is the default. If you do nothing, you’re on it.
• Salaried individuals can switch every financial year (e.g., declare one to your employer in January, still choose the other when filing the ITR in July if the math favours it).
• Choosing the old regime when filing typically requires the prescribed form (e.g., Form 10-IEA) within the filing timeline — check the current ITR process.
• Use the official income tax department calculator or a reputable one and run both with your real numbers before deciding.

Frequently asked questions

Which tax regime is better, old or new? For most salaried people without large deductions, the new regime — income up to ₹12.75 lakh (salaried) can be tax-free. The old regime wins only if your deductions are large enough to beat the new regime’s lower rates. Compute both.

Is income up to ₹12 lakh tax-free? Under the new regime, yes for resident individuals — the Section 87A rebate makes tax zero up to ₹12 lakh taxable income (₹12.75 lakh gross for salaried after the ₹75,000 standard deduction), excluding special-rate income. NRIs can’t claim this rebate.

Can I switch between regimes every year? Salaried individuals can choose afresh each financial year, including switching at ITR-filing time from what they declared to their employer.

Does the new regime allow any deductions? A few — notably the ₹75,000 standard deduction for salaried and employer NPS under 80CCD(2) up to 14% of basic. Most others (80C, HRA, home loan interest) are not available.

Which regime is the default? The new regime is the default. You must actively opt for the old regime if it’s better for you.

Did Budget 2026 change the tax slabs? No. Budget 2026 retained the FY 2025-26 slab structure for FY 2026-27. The standard deduction (₹75,000 new regime) and ₹12 lakh rebate threshold continue.

I have a home loan and pay high rent — which regime? That profile (significant HRA + home loan interest + 80C + 80D) often favours the old regime. Run both calculations with your exact figures to confirm.

Where to go from here

Don’t pick a regime by reputation. Take 15 minutes once a year, plug your real income and deductions into both, and choose the lower number. For most people with simple finances that’s the new regime; for high-deduction profiles it can still be the old one.
