Module G: Interactive FAQ

What is the difference between the old and new tax regimes?

The key differences are:

• Tax Slabs: New regime has 6 slabs (0%-30%) vs old regime’s 3 slabs (5%-30%)
• Deductions: New regime allows limited deductions (only standard deduction + NPS), while old regime allows all traditional deductions (80C, 80D, HRA, etc.)
• Rebate: New regime offers full rebate up to ₹7 lakh income vs ₹5 lakh in old regime
• Surcharge: Applied similarly in both regimes for income above ₹50 lakh
• Default Option: New regime is now the default choice since FY 2023-24

Use our calculator to compare which regime is better for your specific income level and deductions.

How is the standard deduction calculated in both regimes?

Since FY 2023-24:

• New Regime: Flat ₹50,000 standard deduction for all taxpayers
• Old Regime: ₹50,000 standard deduction (previously ₹40,000 transport allowance + ₹15,000 medical allowance)

This deduction is automatically applied in our calculator for both regimes. For pensioners, the standard deduction is also ₹50,000 in both regimes.

What are the surcharge rates for high-income earners?

The surcharge rates (FY 2024-25) are:

Income Range (₹)	Surcharge Rate	Effective Tax Rate (including cess)
50,00,000 – 1,00,00,000	10%	33%
1,00,00,001 – 2,00,00,000	15%	34.5%
2,00,00,001 – 5,00,00,000	25%	37%
Above 5,00,00,000	37%	42.74%

Note: The surcharge is calculated on the income tax amount (before cess), not on the total income. Our calculator automatically applies the correct surcharge based on your income level.

Can I switch between tax regimes every year?

Yes, you can switch between the old and new tax regimes every financial year, with these conditions:

• Salaried Individuals: Can choose regime at the start of each financial year (April 1)
• Business Owners/Professionals:
  • Can switch only once in their lifetime (from old to new)
  • Once they opt for new regime, they cannot revert to old regime
  • Must file Form 10-IE to opt for new regime
• Default Choice: If no choice is made, new regime is automatically applied
• ITR Filing: Regime choice must be indicated while filing ITR

Our calculator helps you compare both regimes annually to make an informed decision.

How is the 4% health and education cess calculated?

The health and education cess is calculated as follows:

1. First, calculate the basic income tax (using applicable slabs)
2. Add surcharge if applicable (for income > ₹50 lakh)
3. Calculate 4% of the total (income tax + surcharge)
4. This cess is added to your total tax liability

Example: If your income tax is ₹2,50,000 and surcharge is ₹25,000 (total ₹2,75,000), then cess = 4% of ₹2,75,000 = ₹11,000

Our calculator automatically includes this cess in the total tax calculation.

What documents are required for claiming tax deductions?

To claim tax deductions under the old regime, maintain these documents:

• Section 80C (₹1.5 lakh):
  • PPF passbook
  • ELSS investment statements
  • Life insurance premium receipts
  • Home loan principal repayment certificate
  • Tuition fee receipts for children
• Section 80D (Medical Insurance):
  • Insurance premium payment receipts
  • Preventive health check-up bills
• HRA Exemption:
  • Rent receipts (with landlord’s PAN if rent > ₹1 lakh/year)
  • Rental agreement
  • Landlord’s PAN card copy (if applicable)
• Home Loan Interest (24B):
  • Interest certificate from bank
  • Loan statement
• Education Loan (80E):
  • Loan statement showing interest paid
  • Education institution receipts
• Donations (80G):
  • Receipt from registered charitable organization
  • 80G certificate from the NGO

For the new regime, only standard deduction and NPS contributions require documentation. Always keep digital copies of these documents for at least 6 years from the end of the relevant assessment year.

How does the calculator handle income from multiple sources?

Our calculator is designed to handle composite income from various sources:

1. Salary Income: Includes basic, DA, HRA, allowances, bonuses
2. House Property: Rental income (after 30% standard deduction and municipal taxes)
3. Capital Gains:
   • Short-term capital gains (STCG) – taxed at 15% (equity) or slab rate (others)
   • Long-term capital gains (LTCG) – taxed at 10% (equity above ₹1 lakh) or 20% (others with indexation)
4. Business/Profession: Net profit after expenses
5. Other Sources: Interest income, dividends, lottery winnings, etc.

Important Notes:

• Enter the total annual income from all sources in the calculator
• For capital gains, enter the net taxable amount after exemptions
• Dividend income above ₹5,000 is taxable at slab rates
• Interest income from savings accounts (up to ₹10,000) is exempt under 80TTA
