Old vs New Tax Regime by Salary Bracket: Which One Saves You More at Every Income Level (AY 2026-27)

Why Your Salary Bracket Changes the Answer

The old-vs-new tax regime debate has no universal answer. A taxpayer earning Rs 8 lakh with minimal investments will save more under the new regime, while someone at Rs 20 lakh claiming full deductions may be better off with the old one. The breakeven point — where both regimes produce the same tax liability — shifts depending on your gross income and deduction profile.

This guide gives you a bracket-by-bracket analysis so you can find where you stand without running complex calculations.

The Key Numbers for AY 2026-27

Before diving into brackets, here are the rates that matter:

New Regime Slabs (Default)

Standard deduction: Rs 75,000. Section 87A rebate applies up to taxable income of Rs 12,00,000 (effective zero tax up to roughly Rs 12.75 lakh gross salary).

Old Regime Slabs

Standard deduction: Rs 50,000. Full access to deductions under sections 80C, 80D, 80CCD(1B), 80E, HRA, LTA, and Section 24(b).

Bracket 1: Gross Salary Up to Rs 10 Lakh

Verdict: New regime wins for most taxpayers.

Under the new regime, taxable income after the Rs 75,000 standard deduction is Rs 9,25,000. Tax comes to Rs 20,000 + Rs 12,500 = Rs 32,500 before cess. With the Section 87A rebate available for taxable income up to Rs 12 lakh, the actual tax payable is zero if your taxable income stays at or below Rs 12 lakh.

For someone earning Rs 10 lakh gross:

• New regime tax: Rs 0 (rebate applies)
• Old regime tax (with Rs 2 lakh deductions): approximately Rs 54,600 including cess

Even if you claim the full Rs 1.5 lakh under 80C plus Rs 50,000 standard deduction, your old regime taxable income of Rs 8 lakh still attracts around Rs 52,500 plus cess.

When the old regime could still make sense here: If you receive a large HRA component (paying Rs 25,000+ monthly rent in a metro) and also claim 80C, 80D, and NPS deductions totalling over Rs 3 lakh, the old regime might edge ahead. But for most taxpayers at this salary level without high rent, the new regime's zero-tax benefit via Section 87A is hard to beat.

Bracket 2: Gross Salary Rs 10–15 Lakh

Verdict: New regime usually wins unless deductions exceed Rs 3.75 lakh.

This is the bracket where the decision becomes genuinely close. Let us work through a realistic example.

Example — Rs 12.5 lakh CTC, Bengaluru

Salary components: Basic Rs 5 lakh, HRA Rs 2.5 lakh, Special Allowance Rs 5 lakh.

New regime:

• Gross salary: Rs 12,50,000
• Less standard deduction: Rs 75,000
• Taxable income: Rs 11,75,000
• Tax: Rs 20,000 + Rs 37,500 = Rs 57,500
• Less rebate u/s 87A (taxable income ≤ Rs 12 lakh): Rs 0 tax

Wait — Rs 11,75,000 is below Rs 12 lakh, so the rebate wipes out the entire liability. Effective tax: nil.

Old regime (with common deductions):

• 80C: Rs 1,50,000 (EPF + ELSS)
• 80D: Rs 25,000 (health insurance)
• HRA exemption: Rs 1,20,000 (rent Rs 20,000/month in metro, basic Rs 5 lakh)
• Standard deduction: Rs 50,000
• Taxable income: Rs 12,50,000 – Rs 3,45,000 = Rs 9,05,000
• Tax: Rs 12,500 + Rs 81,000 = Rs 93,500
• Plus 4% cess: Rs 97,240

The new regime saves nearly Rs 97,000 in this scenario. You would need your total deductions to reduce old-regime taxable income below Rs 5 lakh for the old regime to compete — that means over Rs 7.5 lakh in deductions, which is unrealistic at this salary.

Breakeven deduction amount at Rs 12.5 lakh salary: Approximately Rs 3.75 lakh. If your total deductions (including HRA) cross this threshold, run the numbers carefully — but the new regime's rebate gives it a structural advantage.

Bracket 3: Gross Salary Rs 15–20 Lakh

Verdict: Closely contested. Depends heavily on HRA and loan interest.

Above Rs 12.75 lakh gross income, the Section 87A rebate no longer applies under the new regime. This narrows the new regime's advantage significantly.

Example — Rs 18 lakh CTC, Mumbai

New regime:

• Taxable income: Rs 18,00,000 – Rs 75,000 = Rs 17,25,000
• Tax: Rs 20,000 + Rs 40,000 + Rs 60,000 + Rs 25,000 = Rs 1,45,000
• Plus employer NPS (if applicable, exempt up to 14% of basic): let us assume Rs 1.26 lakh exempt
• Revised taxable: Rs 15,99,000
• Tax: approximately Rs 1,19,900
• Plus 4% cess: Rs 1,24,696

Old regime (with substantial deductions):

• 80C: Rs 1,50,000
• 80D: Rs 50,000 (self + parents)
• 80CCD(1B): Rs 50,000
• HRA: Rs 2,40,000 (rent Rs 35,000/month, metro, basic Rs 7.2 lakh)
• Section 24(b) home loan interest: Rs 2,00,000
• Standard deduction: Rs 50,000
• Total deductions: Rs 7,40,000
• Taxable income: Rs 10,60,000
• Tax: Rs 12,500 + Rs 1,00,000 + Rs 18,000 = Rs 1,30,500
• Plus 4% cess: Rs 1,35,720

In this high-deduction scenario, the old regime tax is Rs 1,35,720 versus new regime at Rs 1,24,696. The new regime still wins by about Rs 11,000. But if this taxpayer also claims LTA of Rs 50,000 and professional tax of Rs 2,400, the old regime could close the gap or pull ahead.

Breakeven deduction threshold at Rs 18 lakh: Around Rs 7.5–8 lakh in total deductions. This is achievable only if you have both high rent payments AND an active home loan — an unusual combination (typically you claim one or the other).

Bracket 4: Gross Salary Rs 20–30 Lakh

Verdict: Old regime can win if you can claim Rs 8+ lakh in deductions.

At higher incomes, the old regime's 30% slab kicks in at Rs 10 lakh taxable income, while the new regime's 30% slab starts only above Rs 24 lakh. This gives the new regime a structural advantage through lower marginal rates in the Rs 10–24 lakh range.

Example — Rs 25 lakh CTC

New regime:

• Taxable income: Rs 24,25,000
• Tax: Rs 20,000 + Rs 40,000 + Rs 60,000 + Rs 80,000 + Rs 1,00,000 + Rs 6,250 = Rs 3,06,250
• Plus cess: Rs 3,18,500

Old regime (maximum realistic deductions):

• Deductions: 80C (Rs 1.5L) + 80D (Rs 75K with senior citizen parents) + 80CCD(1B) (Rs 50K) + HRA (Rs 3L at Rs 45K rent) + 24(b) (Rs 2L) + standard deduction (Rs 50K) = Rs 8,25,000
• Taxable income: Rs 16,75,000
• Tax: Rs 12,500 + Rs 1,00,000 + Rs 2,02,500 = Rs 3,15,000
• Plus cess: Rs 3,27,600

Even with Rs 8.25 lakh in deductions, the new regime wins by about Rs 9,000. The old regime only pulls ahead if deductions cross Rs 8.5–9 lakh — possible but it requires maxing out every available exemption.

Bracket 5: Gross Salary Above Rs 30 Lakh

Verdict: New regime wins for most; old regime needs Rs 10+ lakh deductions to compete.

At Rs 30 lakh and above, the new regime's graduated rates between Rs 12–24 lakh (10%, 15%, 20%, 25%) are substantially lower than the old regime's flat 30% above Rs 10 lakh. The tax saving from lower slab rates compounds with income.

The deduction threshold to break even at Rs 35 lakh salary is approximately Rs 11–12 lakh — nearly impossible unless you have an extremely high HRA exemption in Mumbai or Delhi combined with full home loan interest on a second property.

Practical takeaway: At this income level, the new regime is almost always better. Focus on the limited deductions that still apply — employer NPS contribution and standard deduction — and invest the tax savings elsewhere rather than chasing old-regime deductions.

Quick-Reference Breakeven Table

How to Decide in 3 Minutes

1. Add up your actual deductions. Include 80C, 80D, 80CCD(1B), HRA exemption, Section 24(b), and standard deduction (Rs 50,000 in old regime). Don't include aspirational investments you might make — count only what you will definitely claim.

2. Compare against the breakeven threshold for your salary bracket from the table above.

3. If your deductions fall short of the breakeven by Rs 50,000 or more, the new regime is better. If you are within Rs 50,000 of the breakeven, calculate both scenarios precisely — or let 49Tax's regime comparison tool do it for you with your actual salary components.

Common Situations Where Old Regime Still Wins

• High rent in a metro + modest salary (Rs 15–20L): If your HRA exemption alone is Rs 2.5–3 lakh and you claim 80C + 80D + NPS, total deductions can cross the breakeven
• Active home loan on expensive property: Section 24(b) gives Rs 2 lakh deduction that compounds with other exemptions
• Senior citizen parents without insurance: 80D allows Rs 50,000 for health insurance of senior citizen parents (total Rs 75,000 with your own premium)
• Multiple deduction sources stacked: EPF (auto 80C) + voluntary ELSS + NPS + medical insurance + home loan interest together can cross Rs 8 lakh

When to Stick with New Regime Without Thinking

• Your only deduction is EPF (which goes toward 80C but you cannot claim it under new regime anyway)
• You live in your own house or pay rent below Rs 15,000/month
• Your CTC is below Rs 12.75 lakh
• You have no home loan
• You prefer simpler filing with fewer documents

A Note on Switching

You can switch between regimes every year if you are salaried and don't have business income. There is no lock-in. Inform your employer of your choice at the beginning of the financial year for correct TDS deduction, and confirm at filing time. 49Tax automatically calculates both scenarios during filing and highlights which regime saves more based on your actual Form 16 data.

The Bottom Line

For AY 2026-27, the new regime's expanded slabs and Rs 75,000 standard deduction make it the default winner for roughly 70-80% of salaried taxpayers. The old regime remains viable only in specific high-deduction scenarios — primarily taxpayers paying significant rent in metros while also servicing a home loan. If your total claimable deductions do not cross the breakeven threshold for your bracket, the new regime saves you both tax and paperwork.

Rather than guessing, calculate both options with your actual numbers. A Rs 5,000 difference in the wrong direction every year compounds into lakhs over a career.
