New Tax Regime Vs Old Tax Regime 2026

Q: How do I calculate which tax regime is better for me?

Step 1: Add up all deductions you can claim in old regime -- 123, 126, HRA, home loan interest, NPS, LTA, standard deduction Rs 50,000. Step 2: Subtract from gross income to get taxable income under old regime. Step 3: Calculate tax on that taxable income using old regime slabs. Step 4: Calculate tax on gross income minus Rs 75,000 standard deduction using new regime slabs, then subtract 156 rebate if applicable. Step 5: Compare both.

New Tax Regime vs Old Tax Regime 2026 : Which is Better

Every year between January and March, crores of salaried Indians face the same question from their HR or payroll department: “New regime ya old regime?”

Table of Contents

Most people pick one without actually calculating which saves them more money. Some blindly follow their colleague’s choice. Some pick the same regime as last year without checking if anything changed.

This article ends the confusion. You will get the exact breakeven point, a salary-wise decision table from Rs 5 lakh to Rs 20 lakh, and a clear answer for your specific situation — all verified from incometaxindia.gov.in and Finance Bill 2026. From April 1, 2026, the new regime is the default for all taxpayers. If you do not declare your choice, you are automatically placed in the new regime.

Key Difference — New Tax Regime vs Old Tax Regime 2026 at a Glance

The fundamental trade-off is simple: new regime gives you lower tax rates in exchange for giving up almost all deductions. Old regime keeps all deductions but taxes you at higher rates.

Factor	New Tax Regime	Old Tax Regime
Default status	Default — auto-selected if no choice made	Opt-in — you must actively choose this
Basic exemption limit	Rs 4,00,000	Rs 2,50,000
Standard deduction (salaried)	Rs 75,000	Rs 50,000
Section 156 rebate	Rs 60,000 if income up to Rs 12,00,000	Rs 12,500 if income up to Rs 5,00,000
Tax rates	Lower — 5% to 30% with more slabs	Higher — 5% / 20% / 30%
Section 156 (ELSS, PPF, LIC etc.)	Not available	Up to Rs 1,50,000
Section 126 (medical insurance)	Not available	Up to Rs 25,000 / Rs 50,000
HRA exemption	Not available	Available — minimum of 3 conditions
Home loan interest (Section 22)	Not available	Up to Rs 2,00,000
NPS employer contribution 124	Available — only major deduction	Available

Tax Slab Comparison — New Tax Regime vs Old Tax Regime 2026

Income Slab	New Regime Rate	Old Regime Rate (below 60 yrs)	Difference
Up to Rs 2,50,000	Nil	Nil	Same
Rs 2,50,001 — Rs 4,00,000	Nil	5%	New regime better
Rs 4,00,001 — Rs 5,00,000	5%	5%	Same rate
Rs 5,00,001 — Rs 8,00,000	5%	20%	New regime much better
Rs 8,00,001 — Rs 10,00,000	10%	20%	New regime better
Rs 10,00,001 — Rs 12,00,000	10%	30%	New regime much better
Rs 12,00,001 — Rs 16,00,000	15%	30%	New regime better — but deductions can bridge this gap
Above Rs 16,00,000	20% to 30%	30%	New regime still better at base — deductions determine winner

The slab comparison shows why the new regime wins at lower incomes — the 5-to-20 lakh range is taxed at 5-10% in new regime versus 20-30% in old regime. The only reason to choose old regime is when deductions are large enough to bring your taxable income down below the point where new regime rates kick in harder.

The Breakeven Point — When Does Old Regime Win?

The breakeven point is the total deduction amount at which old regime tax equals new regime tax. If your actual deductions exceed this breakeven — old regime saves more. Below it — new regime is better.

Gross Annual Income	New Regime Tax	Old Regime Tax (zero deductions)	Breakeven Deduction	Old Regime Better If Deductions Exceed
Rs 5,00,000	Zero (156 rebate)	Zero (156 rebate)	No breakeven	New regime always equal or better at Rs 5L
Rs 7,50,000	Rs 19,500	Rs 65,000	~Rs 2,00,000	Old regime better if deductions exceed Rs 2L
Rs 10,00,000	Rs 45,000	Rs 1,12,500	~Rs 3,25,000	Old regime better if deductions exceed Rs 3.25L
Rs 12,00,000	Zero (156 rebate)	Rs 1,72,500	~Rs 5,00,000	Old regime better only with very high deductions
Rs 15,00,000	Rs 90,000	Rs 2,62,500	~Rs 4,25,000	Old regime better if deductions exceed Rs 4.25L
Rs 20,00,000	Rs 1,70,000	Rs 4,12,500	~Rs 5,50,000	Old regime better if deductions exceed Rs 5.5L

Note: All figures approximate. Old regime tax calculated before standard deduction Rs 50,000. New regime tax calculated before standard deduction Rs 75,000.

Practical reading: at Rs 10 lakh income, if your total deductions (123 + 126 + HRA + home loan interest + NPS) add up to more than approximately Rs 3.25 lakh — old regime saves more tax. If your deductions are less than Rs 3.25 lakh — new regime is better.

Who Should Choose What — Salary-Wise Decision Guide

Your Profile	Annual Income	Typical Deductions Available	Recommended Regime	Why
Fresh graduate, first job, renting	Rs 5L — Rs 7.5L	Low — mostly only 123 EPF	New Regime	156 rebate makes tax zero or minimal. No home loan, no HRA from employer.
Mid-career salaried, renting, no home loan	Rs 8L — Rs 12L	Moderate — 123, 126, some HRA	New Regime likely	New regime rates are so much lower in 5-12L range. Check calculation.
Salaried with home loan, max 123	Rs 10L — Rs 15L	High — home loan Rs 2L + 123 Rs 1.5L + 126 Rs 25K + NPS Rs 50K = Rs 4.25L+	Old Regime	Total deductions exceed breakeven. Old regime reduces taxable income significantly.
High earner, multiple deductions	Rs 15L — Rs 20L	Very High — home loan + 123 + 126 + HRA + NPS	Old Regime likely	Deductions can reduce taxable income by Rs 5-6L, making old regime better.
High earner, no home loan, minimal deductions	Rs 15L+	Low — only standard deduction	New Regime	Without home loan and HRA, deductions rarely exceed breakeven at higher incomes.
Senior citizen (60+ yrs), pension income	Any amount	Low to moderate	New Regime usually	Basic exemption Rs 3L in old regime vs Rs 4L in new. New regime has higher exemption.

The Section 156 Rebate Warning Most Articles Miss

Section 156 gives you a rebate of Rs 60,000 in the new regime (or Rs 12,500 in the old regime) that reduces your tax to zero within the specified income limit. But there is a critical caveat that almost every tax article fails to mention clearly.

Income Type	156 Rebate Applies?	Tax Rate
Salary income	Yes — rebate applies fully	Slab rate reduced by rebate
Interest income (FD, savings account)	Yes — rebate applies	Slab rate reduced by rebate
LTCG from equity mutual funds (Section 198)	No — rebate does NOT apply	12.5% on gains above Rs 1.25 lakh
STCG from equity mutual funds (Section 196)	No — rebate does NOT apply	20% on entire STCG amount
LTCG from property (Section 197)	No — rebate does NOT apply	12.5% without indexation

Practical example: Rahul has salary income of Rs 10 lakh and LTCG of Rs 2 lakh from mutual fund redemption. In new regime, his salary tax is zero (156 rebate covers it). But his Rs 2 lakh LTCG is taxed at 12.5% — Rs 25,000 tax (on the Rs 75,000 above the Rs 1.25 lakh exemption). He cannot use the 156 rebate to offset this LTCG tax.

How to Switch Between Regimes

Switching regimes is allowed but the rules differ based on your income type.

Taxpayer Type	Can Switch?	How Often	How to Switch
Salaried (no business income)	Yes	Every year — different choice allowed each year	Inform employer at start of year for TDS. Formally opt when filing ITR.
Business or professional income	Limited	One-time switch from new to old only. Once switched from old to new, stays in new.	File Form 10-IE before due date to opt out of new regime.
HUF or AOP	Yes	Every year (if no business income)	Same as salaried — declare at time of ITR filing.

Important: the new regime is the default. If you want old regime, you must actively opt for it. If you miss declaring and stay in new regime, you can correct this only at the time of ITR filing — not after.

Frequently Asked Questions (FAQs)

Is the new tax regime better than the old tax regime in 2026?

For most taxpayers with low to moderate deductions, the new regime is better. The new regime has lower slab rates in the Rs 4 lakh to Rs 12 lakh range and offers Rs 12.75 lakh effective zero-tax for salaried employees. Old regime becomes better only when total deductions (123 + 126 + HRA + home loan + NPS) exceed approximately Rs 3.25 lakh at Rs 10 lakh income or Rs 4.25 lakh at Rs 15 lakh income. Calculate both before deciding.

If I have filed ITR in old regime, can I file revised ITR in new regime ?

No, an ITR filed in one regime can be revised in that regime only. If you have filed ITR in old regime, you can file revised ITR in old regime only. For new provision regarding revised return Click Here.

Yes, at the time of ITR filing, you can formally choose either regime regardless of what you told your employer and regardless of your Form 16.

To choose old regime, you must actively opt out of the new regime.

Does 156 rebate apply to LTCG from mutual funds in 2026?

No. Section 156 rebate (Rs 60,000 in new regime, Rs 12,500 in old regime) does NOT apply to Long Term Capital Gains taxed under Section 198 (equity mutual funds and shares) or Short Term Capital Gains under Section 196. Even if your total income including LTCG is below Rs 12 lakh in the new regime, the LTCG portion will be taxed at 12.5% and you cannot use 156 to offset it. Section 156 has been amended to provide that special rate incomes will not get benefit of this rebate.

What deductions are allowed in the new tax regime in 2026?

The new tax regime allows only: standard deduction of Rs 75,000 for salaried employees and pensioners, and employer’s NPS contribution under Section 124. All other major deductions — 123, 126, HRA, home loan interest (Section 22), LTA, NPS employee contribution 124, and Section 129 education loan — are NOT available in the new regime.

How do I calculate which tax regime is better for me?

Step 1: Add up all deductions you can claim in old regime — 123, 126, HRA, home loan interest, NPS, LTA, standard deduction Rs 50,000. Step 2: Subtract from gross income to get taxable income under old regime. Step 3: Calculate tax on that taxable income using old regime slabs. Step 4: Calculate tax on gross income minus Rs 75,000 standard deduction using new regime slabs, then subtract 156 rebate if applicable. Step 5: Compare both.

Conclusion

The new vs old regime debate has one clean answer: it depends on your deductions. The new regime wins when deductions are low. The old regime wins when deductions are high enough to cross the breakeven.

For most young salaried professionals without a home loan, new regime is almost always better. For those with a home loan, max 123 investments, NPS, and medical insurance — old regime often saves more tax at incomes of Rs 10 lakh and above. The most important thing: do not guess. Calculate both using the tables in this article. And remember — switching is allowed every year for salaried employees. If your situation changes (you buy a house, you start NPS), recalculate and switch if needed.
