• Above ₹15,00,000: 30%

Old Tax Regime

The old regime maintains higher tax rates but allows deductions under various sections. The tax slabs are:

• Up to ₹2,50,000: Nil
• ₹2,50,001 to ₹5,00,000: 5%

Surcharge and Cess

For income above ₹50 lakh, surcharge applies:

• ₹50 lakh to ₹1 crore: 10% surcharge
• ₹1 crore to ₹2 crore: 15% surcharge

Additionally, Health and Education Cess of 4% is applied to the total tax + surcharge.

Real-World Examples

Case Study 1: Salaried Individual (₹12,00,000 Income)

Scenario: Ramesh, 35, earns ₹12 lakh annually with ₹1.5 lakh in deductions (80C, 80D, HRA).

New Regime: Taxable income = ₹12,00,000. Tax = ₹93,000 (7.75% effective rate).

Old Regime: Taxable income = ₹10,50,000. Tax = ₹1,12,500 + cess (10.25% effective rate).

Recommendation: New regime saves ₹19,500 in this case.

Case Study 2: Senior Citizen (₹8,00,000 Income)

Scenario: Sita, 65, has ₹8 lakh pension income with ₹2 lakh in medical expenses (80D).

New Regime: Taxable income = ₹8,00,000. Tax = ₹25,000 (3.125% effective rate).

Old Regime: Taxable income = ₹6,00,000. Tax = ₹20,600 + cess (2.725% effective rate).

Recommendation: Old regime better due to higher basic exemption (₹3 lakh for seniors).

Case Study 3: High Net Worth Individual (₹2,00,00,000 Income)

Scenario: Amit, 42, earns ₹2 crore annually with ₹50,000 in deductions.

New Regime: Taxable income = ₹2,00,00,000. Tax = ₹54,30,000 + 25% surcharge + 4% cess = ₹70,80,600 (35.4% effective rate).

Old Regime: Taxable income = ₹1,99,50,000. Tax = ₹59,85,000 + 25% surcharge + 4% cess = ₹77,50,350 (38.75% effective rate).

Recommendation: New regime saves ₹6,69,750 despite high income.

Interactive FAQ

What is the difference between old and new tax regimes?

The old regime offers higher tax rates but allows deductions (80C, 80D, HRA, etc.), while the new regime has lower rates but disallows most deductions. The new regime is now the default option, but taxpayers can opt for the old regime if it’s more beneficial.

Key differences:

• New regime has 6 tax slabs vs 3 in old regime
• New regime offers rebate up to ₹7 lakh vs ₹5 lakh in old regime
• Standard deduction of ₹50,000 is automatic in new regime
• Old regime allows exemptions like HRA, LTA, and various Chapter VI-A deductions

How is surcharge calculated on income tax?

Surcharge is an additional tax levied on the income tax amount for high-income individuals. The rates are:

• 10% for income between ₹50 lakh and ₹1 crore
• 15% for income between ₹1 crore and ₹2 crore
• 25% for income between ₹2 crore and ₹5 crore
• 37% for income above ₹5 crore

Surcharge is calculated on the income tax amount before adding cess. For example, if your income tax is ₹10 lakh and your total income is ₹1.2 crore, you’ll pay 15% surcharge (₹1.5 lakh) plus 4% cess on the total.

What is Section 87A rebate and who can claim it?

Section 87A provides a tax rebate to resident individuals with net taxable income up to certain limits:

• New Regime: Full rebate if income ≤ ₹7 lakh (rebate amount = income tax or ₹25,000, whichever is lower)
• Old Regime: Full rebate if income ≤ ₹5 lakh (rebate amount = income tax or ₹12,500, whichever is lower)

This means if your taxable income is within these limits, your net tax liability becomes zero after rebate. Note that the rebate is applied after calculating the tax but before adding cess.

How does the calculator handle deductions in the new regime?

In the new tax regime, most deductions and exemptions are not allowed except for:

• Standard deduction of ₹50,000 (automatically applied)
• Deduction for employer’s contribution to NPS (Section 80CCD(2))
• Deduction for agri-income up to ₹5,000

Our calculator automatically applies the standard deduction in the new regime. For the old regime, you need to manually enter your eligible deductions in the provided field.

What documents are needed for income tax filing?

For accurate tax filing, keep these documents ready:

1. Form 16 (from employer)
2. Salary slips
3. Bank statements and passbooks
4. Investment proofs (for deductions)
5. Rent receipts (for HRA)
6. Home loan statement (for interest deduction)
7. Form 26AS (tax credit statement)
8. Aadhaar card and PAN card
9. Capital gains statements (if applicable)
10. Foreign income details (if any)

For business income, maintain profit/loss statements, balance sheets, and audit reports if applicable.

Can I switch between tax regimes every year?

Yes, you can choose between the old and new tax regimes every financial year when filing your income tax return. However, there are some important considerations:

• For salaried individuals, the choice must be communicated to the employer at the start of the financial year for TDS purposes
• Business owners and professionals can switch every year when filing ITR
• Once you opt for the new regime with certain business income concessions, you cannot switch back for that business
• Compare both regimes using our calculator before making a decision

It’s recommended to evaluate both regimes annually as your income and deduction pattern may change.

How is income from capital gains taxed?

Capital gains tax depends on the type of asset and holding period:

Short-Term Capital Gains (STCG):

• Equity shares/equity funds: 15% tax if sold within 12 months
• Debt funds: Added to income and taxed as per slab
• Property: Added to income and taxed as per slab

Long-Term Capital Gains (LTCG):

• Equity shares/equity funds: 10% tax on gains > ₹1 lakh (holding >12 months)
• Debt funds: 20% with indexation (holding >36 months)
• Property: 20% with indexation (holding >24 months)

Our calculator currently focuses on income from salary/business. For comprehensive tax calculation including capital gains, consult a tax professional.
