🔧 How Tax Regime Comparison Works
Step 1: Calculate Old Regime Tax
The old regime allows numerous deductions but has higher tax slabs.
Formula:
Taxable Income = Gross Income – Standard Deduction (₹50k) – 80C – 80D – HRA – Other – Employer NPS
Tax Calculation:
• Up to ₹2.5L: 0% (₹3L for 60-80, ₹5L for 80+)
• ₹2.5-5L: 5%
• ₹5-10L: 20%
• Above ₹10L: 30%
Rebate u/s 87A: If tax ≤ ₹12,500 → Zero tax
Step 2: Calculate New Regime Tax
The new regime has lower slabs but limited deductions.
Formula:
Taxable Income = Gross Income – Standard Deduction (₹75k) – Employer NPS
Tax Calculation:
• ₹0-4L: 0%
• ₹4-8L: 5%
• ₹8-12L: 10%
• ₹12-16L: 15%
• ₹16-20L: 20%
• ₹20-24L: 25%
• Above ₹24L: 30%
Rebate: If income ≤ ₹12L → Zero tax
Step 3: Add Surcharge & Cess
Surcharge (on Income Tax):
• Income >₹50L-1Cr: 10%
• >₹1Cr-2Cr: 15%
• >₹2Cr-5Cr: 25%
• >₹5Cr: 37%
Health & Education Cess: 4% on (Tax + Surcharge)
Total Tax = Income Tax + Surcharge + Cess
Step 4: Compare & Recommend
The calculator compares total tax under both regimes and recommends the one with lower liability.
❓ Frequently Asked Questions
What is the difference between old and new tax regimes?
Old regime allows numerous deductions (80C, HRA, home loan interest, etc.) but has higher tax slabs. New regime has lower slabs but limits deductions to only standard deduction (₹75,000) and employer NPS, making it simpler but potentially more expensive if you have significant deductions.
Which regime is default for FY 2025-26?
The new tax regime is the default. If you want to opt for the old regime, you must explicitly choose it by filing Form 10-IE with your ITR. If you don’t make a choice, new regime applies automatically.
What are the new regime tax slabs for FY 2025-26?
New regime slabs: ₹0-4L (0%), ₹4-8L (5%), ₹8-12L (10%), ₹12-16L (15%), ₹16-20L (20%), ₹20-24L (25%), Above ₹24L (30%). Important: Rebate zeros tax up to ₹12 lakh income!
How does age affect tax in old regime?
Basic exemption limits vary by age: Below 60: ₹2.5 lakh | 60-80: ₹3 lakh | Above 80: ₹5 lakh. This means senior citizens pay less tax. New regime has no age-based exemption (₹4 lakh for all).
What deductions are allowed in new regime?
Very limited! Only: 1) Standard deduction of ₹75,000 for salaried individuals, and 2) Employer NPS contribution under 80CCD(2). All other popular deductions (80C, 80D, HRA, home loan interest) are NOT allowed.
What is surcharge and when does it apply?
Surcharge is an additional tax on high incomes: >₹50L-1Cr: 10% | >₹1Cr-2Cr: 15% | >₹2Cr-5Cr: 25% | >₹5Cr: 37%. It’s calculated on income tax amount, then 4% health & education cess is added on (tax + surcharge).
Can I switch regimes every year?
Salaried individuals: Yes, you can switch annually. Business/profession income: You can switch once, but if you revert to old regime, you’re permanently locked into new regime thereafter.
What is the ₹12 lakh rebate in new regime?
If your total income in new regime is ≤ ₹12 lakh, the entire tax becomes zero due to rebate. This means effectively zero tax for incomes up to ₹12L. Old regime has rebate only up to ₹5 lakh income.
Should I still invest in 80C if choosing new regime?
Tax-wise, no benefit. However, investments like EPF, PPF, NPS are still valuable for retirement planning and employer matching (e.g., EPF 12% employer contribution). Don’t stop investing just for tax!
Is HRA exemption available in new regime?
No. HRA exemption under Section 10(13A) is only available in old regime. If you’re paying high rent (₹1.5L+ exemption), old regime might be better.
What if I have a home loan?
Home loan interest (up to ₹2 lakh under 24b) is deductible only in old regime. If your home loan interest is high, old regime often wins despite lower slabs in new regime.
Can I claim both standard deduction and 80C?
Old regime: Yes, ₹50,000 standard deduction + all 80C/80D/HRA. New regime: ₹75,000 standard deduction + employer NPS only. No 80C/80D.
When should I consult a CA?
If you have: 1) Business income with complex expenses, 2) Capital gains from property/stocks, 3) Income from multiple sources, 4) Foreign income/assets, or 5) Income >₹50 lakh. CAs can optimize across various sections.

💡 5 Expert Tips
Professional advice to get the most from Old vs New Tax Regime Calculator
Compare Both Regimes Every April Before Informing HR
The new tax regime is default from FY 2023-24. But if you have home loan, HRA, and LIC premium, old regime may save more. Always use an income tax calculator to compare BEFORE you inform your employer at the start of each financial year in April.
Max Out NPS Beyond 80C for Extra ₹50,000 Deduction
Section 80CCD(1B) allows ₹50,000 additional NPS deduction over and above the ₹1.5L 80C limit. At 30% bracket, this saves ₹15,450/year extra. Open NPS on the NSDL portal and invest ₹4,167/month to claim the full deduction every year.
Harvest ₹1.25 Lakh LTCG Tax-Free Each Year
Long-term capital gains up to ₹1.25 lakh per year from equity/mutual funds are completely tax-free. Systematically sell and rebuy mutual fund units each March to "harvest" up to ₹1.25L in gains tax-free annually. This can save ₹15,000+/year over your investing life.
Claim HRA Even If Parents Own the House
If you pay rent to your parents (where they own the house), you can legitimately claim HRA exemption. Your parents must declare this as rental income (taxable in their hands, but often in lower bracket). Family tax planning through legitimate rent can save ₹30,000–₹80,000/year.
Use Form 12BB Correctly — Declare All Savings in April
Submit Form 12BB to your employer at the start of the financial year declaring all planned 80C, 80D, HRA, and home loan investments. If you under-declare, HR deducts higher TDS. If over-declared, you get a refund later but lose liquidity. Calculate accurately upfront.
