Module G: Interactive FAQ – Your Tax Questions Answered
Which tax regime is better for me in 2024-25?
The optimal regime depends on your income level and eligible deductions:
- Choose New Regime if:
- Your income is below ₹15,00,000
- You have minimal deductions
- You prefer simpler tax filing
- Choose Old Regime if:
- You have significant deductions (HRA, 80C, etc.)
- Your income exceeds ₹15,00,000
- You have business income with expenses
Our calculator automatically shows you which regime is better for your specific situation. For most salaried individuals with income below ₹20,00,000, the new regime is more beneficial after the 2024 budget changes.
How is HRA exemption calculated in the new tax regime?
Under the new tax regime introduced in Budget 2024, HRA exemption is not available as a separate deduction. However, you can still claim the standard deduction of ₹50,000 (for salaried individuals) which provides some relief.
If you opt for the old regime, HRA exemption is calculated as the minimum of:
- Actual HRA received from employer
- 50% of salary (for metro cities) or 40% (for non-metro)
- Actual rent paid minus 10% of salary
Example: If your salary is ₹80,000/month, HRA is ₹40,000, and rent is ₹30,000 in Delhi:
- Actual HRA: ₹40,000
- 50% of salary: ₹40,000
- Rent – 10% salary: ₹30,000 – ₹8,000 = ₹22,000
- Exemption: ₹22,000 (minimum of above)
What are the changes in tax slabs for FY 2024-25?
The Union Budget 2024 introduced these key changes to tax slabs under the new regime:
| Income Range (₹) | FY 2023-24 Rate | FY 2024-25 Rate |
|---|---|---|
| 0 – 3,00,000 | 0% | 0% |
| 3,00,001 – 6,00,000 | 5% | 5% |
| 6,00,001 – 9,00,000 | 10% | 10% |
| 9,00,001 – 12,00,000 | 15% | 15% |
| 12,00,001 – 15,00,000 | 20% | 20% |
| Above 15,00,000 | 30% | 30% |
Key changes in 2024-25:
- Standard deduction of ₹50,000 introduced in new regime
- Rebate limit under Section 87A increased to ₹7,00,000
- Surcharge rates remain unchanged
- No changes to old regime slabs

Can I switch between old and new tax regimes every year?
Yes, you can switch 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: You must inform your employer at the beginning of the financial year about your regime choice for TDS purposes. You can still change it while filing ITR.
- For Business Owners: Once you opt out of the new regime (by choosing old regime), you can only switch back to the new regime once in your lifetime.
- Form 10IE: If you have business income and want to opt for the new regime, you must file Form 10IE before the due date of filing your return.
- ITR Form: Different ITR forms may apply based on your regime choice and income sources.
Our recommendation: Use our calculator to compare both regimes with your actual numbers before making a decision. The new regime is generally better for incomes below ₹15,00,000, while the old regime may be better for higher incomes with significant deductions.
How is tax calculated on capital gains in 2024-25?
Capital gains tax in FY 2024-25 depends on the asset type and holding period:
1. Equity Shares & Equity Mutual Funds:
- Short-term (≤12 months): 15% tax on gains
- Long-term (>12 months):
- 10% tax on gains exceeding ₹1,00,000
- No indexation benefit
2. Debt Mutual Funds & Gold:
- Short-term (≤36 months): Taxed as per your income slab
- Long-term (>36 months):
- 20% tax with indexation
- 10% tax without indexation (whichever is lower)
3. Property:
- Short-term (≤24 months): Taxed as per income slab
- Long-term (>24 months):
- 20% tax with indexation
- 10% tax without indexation (if held >12 months)
4. Cryptocurrency:
- 30% flat tax on all gains (short or long term)
- No deduction for any expenses except cost of acquisition
- 1% TDS on transactions above ₹10,000
Example: If you sell equity shares purchased for ₹5,00,000 after 18 months for ₹8,00,000:
- Long-term gain: ₹3,00,000
- Taxable gain: ₹3,00,000 – ₹1,00,000 (exemption) = ₹2,00,000
- Tax: 10% of ₹2,00,000 = ₹20,000

How does the standard deduction work in the new tax regime?
From FY 2024-25, the new tax regime includes a standard deduction of ₹50,000 for salaried individuals and pensioners. Here’s how it works:
- Eligibility: Available to all salaried taxpayers and pensioners opting for the new regime
- Amount: Flat ₹50,000 deduction (no proofs required)
- Purpose: Replaces the transport allowance and medical allowance that were available in the old regime
- Calculation: Deduct ₹50,000 from your gross salary before calculating tax
- Impact: Reduces taxable income by ₹50,000, saving up to ₹15,000 in tax (depending on your slab)
Example: If your gross salary is ₹10,00,000:
- Without standard deduction: Taxable income = ₹10,00,000
- With standard deduction: Taxable income = ₹9,50,000
- Tax savings: ₹12,500 (for 25% slab) + 4% cess = ₹13,000
Important notes:
