Module C: Formula & Methodology Behind the Calculator
New Tax Regime (Default)
The new regime offers lower rates but removes most exemptions/deductions. Tax slabs for FY 2024-25:
| Income Range (₹) | Tax Rate | Effective Rate After Rebate |
|---|---|---|
| 0 – 3,00,000 | 0% | 0% |
| 3,00,001 – 6,00,000 | 5% | 0% (full rebate) |
| 6,00,001 – 9,00,000 | 10% | 5% |
| 9,00,001 – 12,00,000 | 15% | 10% |
| 12,00,001 – 15,00,000 | 20% | 13% |
| Above 15,00,000 | 30% | 23% |
Old Tax Regime
Allows deductions under Sections 80C, 80D, HRA, etc. Slabs remain unchanged:
| Age Group | Income Range (₹) | Tax Rate |
|---|---|---|
| Below 60 | 0 – 2,50,000 | 0% |
| 2,50,001 – 5,00,000 | 5% | |
| 5,00,001 – 10,00,000 | 20% | |
| Above 10,00,000 | 30% | |
| 60-80 | 0 – 3,00,000 | 0% |
| 3,00,001 – 5,00,000 | 5% | |
| 5,00,001 – 10,00,000 | 20% | |
| Above 10,00,000 | 30% |
Calculation Logic
The calculator follows this sequence:
- Determine taxable income after standard deduction (₹50,000 for salaried in both regimes)
- Apply regime-specific slabs to calculate base tax
- Add surcharge (10-37% for income > ₹50L) and 4% cess
- Apply Section 87A rebate (full rebate for income ≤ ₹7L in new regime, ≤ ₹5L in old regime)
- Compare both regimes to show optimal choice

Module G: Interactive FAQ – Your Tax Questions Answered
Which tax regime is better for me – old or new? ▼
The optimal regime depends on your income level and eligible deductions:
- Income ≤ ₹7.5L: New regime is usually better due to full rebate under Section 87A
- Income ₹7.5L-₹15L: Compare both regimes using our calculator – new regime often wins if you have limited deductions
- Income > ₹15L: Old regime typically better if you have significant deductions (₹2.5L+)
- Senior Citizens: Old regime often better due to higher exemption limits and deduction benefits
Our calculator automatically shows the better option for your specific situation.
How is surcharge calculated on income tax? ▼
Surcharge is an additional tax on the income tax amount (not on total income) for high earners:
| Income Range (₹) | Surcharge Rate | Effective Rate (incl. cess) |
|---|---|---|
| 50,00,000 – 1,00,00,000 | 10% | 10.4% |
| 1,00,00,001 – 2,00,00,000 | 15% | 15.6% |
| 2,00,00,001 – 5,00,00,000 | 25% | 26% |
| Above 5,00,00,000 | 37% | 38.48% |
Example: For ₹1.2cr income with ₹30L tax, surcharge = 15% of ₹30L = ₹4.5L, plus 4% cess = ₹120k, total = ₹4.62L extra.
What is Section 87A rebate and who can claim it? ▼
Section 87A provides tax rebates to resident individuals:
- New Regime: Full rebate if taxable income ≤ ₹7,00,000 (no tax payable)
- Old Regime: Full rebate if taxable income ≤ ₹5,00,000
- Rebate amount = 100% of income tax or ₹12,500 (old)/₹25,000 (new), whichever is lower
- Not available for NRIs, Hindu Undivided Families (HUFs), or companies
- Automatically applied by our calculator when eligible
Example: For ₹6.5L income in new regime, tax would be ₹25k but rebate reduces it to ₹0.
How are capital gains taxed in India? ▼
Capital gains tax depends on asset type and holding period:
| Asset Type | Short-Term (<36 months) | Long-Term (≥36 months) |
|---|---|---|
| Equity Shares/MF | 15% (STT paid) | 10% (>₹1L) |
| Debt MF | As per slab | 20% with indexation |
| Property | As per slab | 20% with indexation |
| Gold | As per slab | 20% with indexation |
| Cryptocurrency | 30% (flat) | 30% (flat) |
Note: Long-term capital gains up to ₹1L from equity are tax-free. Our calculator includes capital gains in total income for accurate tax computation.
Can I switch between tax regimes every year? ▼
Regime selection rules:
- Salaried Employees: Can choose regime every year when filing ITR
- Business Owners:
- Can switch only once in lifetime (from old to new)
- If you opt for new regime and have business income, you cannot revert to old regime in future years
- Default Rule: New regime is now the default option (pre-filled in ITR forms)
- Form 10-IE: Must be filed if choosing old regime with business income
Our calculator lets you compare both regimes side-by-side to make an informed annual choice.
What documents should I keep for tax filing? ▼
Maintain these documents for 6-8 years:
- Income Proofs:
- Form 16 (salaried)
- Bank statements showing interest income
- Rental agreements (if rental income)
- Capital gains statements from broker
- Deduction Proofs:
- 80C: Investment receipts (ELSS, PPF, LIC)

- Home Loan: Interest certificate from bank
- Other Documents:

- AIS (Annual Information Statement)
- Previous years’ ITR acknowledgments
- Foreign income/asset details (if applicable)

Our calculator aggregates all income sources:
- Salary Income: Includes basic, DA, HRA, bonuses (enter gross amount)
- House Property: Net annual value (rent received minus municipal taxes) minus 30% standard deduction
