Old vs New Tax Regime: Which Saves You More Money?

Quick answer: which tax regime should you pick?

If you don't want to read the full analysis, here's the decision rule that works for 80% of salaried Indians:

Why ₹3.75 lakh? Because the new regime's lower rates create roughly this much advantage. You need deductions exceeding this threshold to offset the rate difference. Below this threshold, the new regime's lower rates win. Above it, the old regime's deductions win.

Now let's look at the actual numbers.

Once you know your post-tax surplus, stress-test what you can invest every month with our SIP calculator, and see how a housing EMI fits the same cash flow using the home loan calculator with prepayment — both numbers feed the same household budget.

New tax regime slabs for FY 2025-26 (AY 2026-27)

The new regime is the default regime since FY 2023-24. You don't need to do anything to opt in — you're automatically on it unless you explicitly choose old regime. Budget 2026 has retained these slabs without changes.

Key features of the new regime

• Standard deduction: ₹75,000 for salaried individuals
• Section 87A rebate: Income up to ₹12 lakh = zero tax (rebate of up to ₹60,000)
• Effectively tax-free for salaried: Up to ₹12.75 lakh (₹12L + ₹75K standard deduction)
• Employer NPS allowed: Section 80CCD(2) deduction available — up to 14% of basic salary
• No 80C, no HRA, no home loan interest: Most popular deductions not available

Old tax regime slabs for FY 2025-26 (AY 2026-27)

You must explicitly opt into the old regime when filing your ITR. For salaried individuals without business income, you can switch between regimes every year.

Key features of the old regime

• Standard deduction: ₹50,000 for salaried individuals
• Section 80C: Up to ₹1,50,000 (PPF, ELSS, EPF, LIC, home loan principal)
• Section 80D: Up to ₹25,000 self + ₹25,000-₹50,000 parents (health insurance)
• HRA exemption: Based on rent paid — significant for metro employees
• Section 24(b): Home loan interest up to ₹2,00,000
• Section 80CCD(1B): Additional ₹50,000 for NPS
• Section 87A rebate: Income up to ₹5 lakh = zero tax

Tax comparison at every income level

This is the table everyone needs to see. Tax calculated under both regimes for a salaried individual with no deductions claimed (pure rate comparison):

Important: This table assumes ZERO deductions under old regime. That's obviously unrealistic — the real question is how much your deductions shift the old regime column. Let's calculate that.

Every deduction available in old regime

The old regime's entire advantage comes from deductions. Here's every major one and its typical value:

Maximum possible deductions: A person claiming all of the above could potentially deduct ₹6-8 lakh from taxable income. This would make old regime significantly better.

Realistic deductions for most people: ₹2.5-4 lakh. This is where the regime choice becomes close and calculation is essential.

The break-even calculation: finding your magic number

Instead of guessing, here's how to find your personal break-even point:

Step 1: Calculate tax under new regime

Take your gross salary, subtract ₹75,000 standard deduction. Apply new regime slabs. This is your new regime tax.

Step 2: Calculate tax under old regime with your actual deductions

Take gross salary, subtract ₹50,000 standard deduction, then subtract all your 80C, 80D, HRA, home loan, NPS deductions. Apply old regime slabs.

Step 3: Compare

Whichever regime produces the lower tax number is your answer.

Break-even deduction thresholds by income

Here's the approximate deduction amount you need under old regime to match new regime's tax:

5 real-life examples with full calculations

Example 1: Fresh graduate — ₹8 LPA, no deductions

Profile: 23 years old, first job, lives with parents, no investments.

• New regime: ₹0 tax (₹12L rebate covers this income)
• Old regime: ~₹49,400 (even with ₹50K standard deduction)
• Winner: New regime saves ₹49,400

Verdict: For anyone earning up to ₹12 lakh, new regime is the obvious choice. Don't overthink it.

Example 2: Mid-career — ₹15 LPA, moderate deductions

Profile: 30 years old, rents in Bangalore (₹22,000/month), has ELSS + PPF.

Deductions claimed:

• Standard deduction: ₹50,000
• 80C (EPF + ELSS): ₹1,50,000
• 80D (health insurance): ₹20,000
• HRA exemption: ₹1,50,000
• Total deductions: ₹3,70,000

• New regime tax: ~₹1,04,000
• Old regime tax: ~₹1,10,000
• Winner: New regime — but barely (₹6,000 difference)

Verdict: At ₹15 LPA with ₹3.7 lakh deductions, it's almost a tie. New regime wins by a small margin. If this person added NPS (₹50K more), old regime would win.

Example 3: Home loan + rent — ₹20 LPA, heavy deductions

Profile: 35 years old, rents in Mumbai (₹35,000/month), has home loan on investment property.

Deductions claimed:

• Standard deduction: ₹50,000
• 80C (EPF + PPF + ELSS + home loan principal): ₹1,50,000
• 80D (self + parents): ₹50,000
• HRA exemption: ₹2,40,000
• Home loan interest (Sec 24b): ₹2,00,000
• NPS (80CCD1B): ₹50,000
• Total deductions: ₹6,40,000

• New regime tax: ~₹2,73,000
• Old regime tax: ~₹1,66,400
• Winner: Old regime saves ₹1,06,600 (₹8,883/month)

Verdict: Heavy deduction users at ₹20 LPA+ save significantly with old regime. The ₹6.4 lakh total deductions are well above the ₹3.75 lakh break-even threshold.

Example 4: Simple salaried — ₹20 LPA, basic deductions only

Profile: 32 years old, lives with parents, minimal investments.

Deductions claimed:

• Standard deduction: ₹50,000
• 80C (EPF only): ₹80,000
• 80D: ₹15,000
• Total deductions: ₹1,45,000

• New regime tax: ~₹2,73,000
• Old regime tax: ~₹3,20,000
• Winner: New regime saves ₹47,000

Verdict: Same ₹20 LPA salary, but without heavy deductions, new regime wins comfortably. This is why the deduction total matters more than income level.

Example 5: Senior professional — ₹30 LPA, maximum deductions

Profile: 40 years old, home loan + rent + full investments.

Deductions claimed:

• Standard deduction: ₹50,000
• 80C (maxed out): ₹1,50,000
• 80D (self + senior parents): ₹75,000
• HRA exemption: ₹3,00,000
• Home loan interest: ₹2,00,000
• NPS: ₹50,000
• Total deductions: ₹7,25,000

• New regime tax: ~₹6,24,000
• Old regime tax: ~₹4,26,400
• Winner: Old regime saves ₹1,97,600 (₹16,467/month)

Verdict: At ₹30 LPA with maxed-out deductions, old regime is a clear winner. The ₹1.97 lakh annual savings is the cost of NOT choosing optimally.

Who should choose which regime?

Choose NEW regime if you are:

• Earning up to ₹12 lakh (zero tax with rebate — no contest)
• Earning up to ₹12.75 lakh if salaried (standard deduction takes you to ₹12L)
• Young professional with minimal investments and no rent/home loan
• Living with parents (no HRA claim possible)
• Someone who doesn't want the hassle of collecting receipts and investment proofs
• Anyone whose total deductions are below ₹3.75 lakh

Choose OLD regime if you have:

• Home loan with significant interest component (₹1.5-2 lakh/year)
• High rent in a metro city (HRA exemption of ₹1-3 lakh/year)
• Maxed out 80C investments (₹1.5 lakh in PPF + ELSS + EPF)
• Health insurance for self + parents (₹50,000-75,000 80D deduction)
• NPS contribution (additional ₹50,000 under 80CCD1B)
• Total deductions exceeding ₹3.75 lakh
• Income above ₹15 lakh — old regime benefits increase with income

5 costly mistakes people make when choosing regimes

Mistake 1: Assuming new regime is always better because slabs are lower

Lower slab rates don't automatically mean lower tax. A person earning ₹25 LPA with ₹5 lakh in deductions saves ₹1.5+ lakh more with old regime despite its higher rates. Always calculate with deductions, not just slabs.

Mistake 2: Forgetting to inform your employer at the start of the year

Your employer deducts TDS based on the regime you declare. If you don't communicate at the start of FY, they use the default new regime. You can still switch when filing ITR, but your monthly in-hand salary will be suboptimal throughout the year. Inform HR in April itself.

See how regime choice affects your in-hand salary with our Salary Calculator.

Mistake 3: Not claiming HRA even when paying rent

Many employees don't submit rent receipts to HR — they just don't bother. HRA exemption for someone paying ₹25,000/month rent in a metro can be ₹1.5-2 lakh per year. That's ₹45,000-60,000 in tax savings at 30% bracket.

Use our HRA Calculator to calculate your exact HRA exemption.

Mistake 4: Not investing enough to make old regime worthwhile

Some people choose old regime because "it has deductions" but only claim ₹1-2 lakh in deductions — well below the ₹3.75 lakh break-even. If you're going to choose old regime, commit to maximizing your deductions.

Minimum deductions you should claim if choosing old regime: 80C maxed (₹1.5 lakh) + 80D (₹25,000+) + NPS (₹50,000) + HRA (variable) = ₹2.75 lakh before HRA. If your HRA pushes this above ₹3.75 lakh, old regime works.

Mistake 5: Not recalculating every year

Your financial situation changes. You might start renting, get a home loan, switch jobs, get a raise, or stop certain investments. What was optimal last year may not be optimal this year. Recalculate every April.
