Interactive FAQ About Income Tax Calculation
What is the difference between the old and new tax regimes? ▼
The key differences are:
- Tax Rates: New regime has lower rates but fewer slabs
- Deductions: Old regime allows 70+ deductions (80C, 80D, HRA etc.) while new regime only allows standard deduction of ₹50,000
- Rebate: New regime offers full rebate for income up to ₹7L (vs ₹5L in old)
- Surcharge: New regime has lower surcharge rates for high earners
From FY 2023-24, the new regime is the default, but you can still choose the old regime when filing returns.
How is income tax calculated on salary with arrears? ▼
Salary arrears are taxed in the year of receipt, but you can claim relief under Section 89(1) by:
- Calculating tax for the year arrears are received
- Calculating what tax would have been in the years the arrears were due
- The difference is the relief amount
Example: If you receive ₹2L arrears in 2024 for work done in 2022, you’ll pay tax on it in 2024 but can claim relief for the higher tax rate in 2024 vs what you would have paid in 2022.
What are the common mistakes to avoid while calculating income tax? ▼
Avoid these critical errors:
- Ignoring TDS: Not reconciling TDS certificates (Form 16/16A) with actual tax liability
- Wrong Regime: Not comparing both regimes before choosing
- Missed Deductions: Forgetting eligible deductions like education loan interest (80E)
- Incorrect HRA: Not calculating HRA exemption correctly (minimum of 3 calculations)
- Late Filing: Missing the July 31 deadline (unless extended) incurs penalties
- Non-disclosure: Not reporting all income sources (even small interest earnings)
- Wrong ITR Form: Using incorrect form (ITR-1 for salary, ITR-3 for business)
How does the 87A rebate work in the new tax regime? ▼
Section 87A provides a full tax rebate for resident individuals with:
- Income up to ₹7,00,000 in new regime (₹5,00,000 in old regime)
- Maximum rebate of ₹25,000 (amount of tax payable)
Example: If your taxable income is ₹6,50,000 in new regime:
- Tax on ₹6,50,000 = ₹25,000 (5% of ₹5L + 10% of ₹1.5L)
- Rebate u/s 87A = ₹25,000
- Net tax = ₹0
Note: The rebate is applied after calculating tax but before adding cess.
