Module G: Interactive FAQ
How does the calculator handle income from multiple sources?
The calculator treats all income as aggregate annual income. For accurate results:
- Include salary, business profit, rental income, capital gains, and other sources
- For capital gains, use the net amount after indexation/exemptions
- Dividend income is taxable at slab rates (no DDT since 2020)
For complex scenarios (e.g., foreign income), consult a CA as special provisions may apply.
What’s the difference between standard deduction and 80C?
| Feature | Standard Deduction | Section 80C |
|---|---|---|
| Amount | ₹50,000 (fixed) | Up to ₹1,50,000 |
| Eligibility | All taxpayers | Only if investments made |
| Nature | Flat reduction | Investment-linked |
| Proof Required | No | Yes (investment proofs) |
| Available in New Regime | Yes | No (except NPS) |
How is surcharge calculated and when does it apply?
Surcharge is an additional tax on the income tax amount (not on total income). The rates are:
- 10%: When total income exceeds ₹50 lakhs
- 15%: When total income exceeds ₹1 crore
- 25%: When total income exceeds ₹2 crores
- 37%: When total income exceeds ₹5 crores
Marginal Relief: If income slightly exceeds a threshold, surcharge is limited to the excess amount. For example:
If income is ₹50,10,000 (just ₹10,000 over ₹50L), surcharge = ₹10,000 × 10% = ₹1,000 instead of 10% on full tax.
Can I switch between tax regimes every year?
Yes, with these conditions:
- Salaried Individuals: Can choose regime every year when filing ITR
- Business Professionals: Can switch only once in lifetime (from old to new)
- Default: New regime is default if no choice is made
- Form 10-IE: Must be filed by business professionals to opt for new regime
Important: Once you opt for new regime as a business, you cannot revert to old regime in future years.
How does the calculator handle the ₹7 lakh rebate under new regime?
The calculator automatically applies the rebate under Section 87A if:
- You select the new tax regime
- Your taxable income is ≤ ₹7,00,000
- You’re a resident individual (not HUF/company)
If eligible, the rebate reduces your tax liability to zero. For example:
- Income: ₹7,00,000
- Tax before rebate: ₹25,000 (5% of ₹5,00,000)
- Rebate: ₹25,000
- Final tax: ₹0
Note: The rebate is limited to the tax amount. If tax is ₹15,000, rebate is ₹15,000.
What documents should I keep for tax filing based on calculator results?
Maintain these documents to support your tax return:
| Deduction/Claim | Required Documents | Retention Period |
|---|---|---|
| Salary Income | Form 16, salary slips | 7 years |
| 80C Investments | Receipts, statements (PPF passbook, ELSS statement, etc.) | 6 years |
| 80D (Medical) | Insurance premium receipts, preventive health checkup bills | 6 years |
| HRA | Rent receipts, rental agreement, landlord’s PAN (if rent > ₹1L/year) | 6 years |
| Home Loan | Interest certificate from bank, possession letter | Until loan closure + 6 years |
| Capital Gains | Purchase/sale deeds, brokerage statements, indexation proof | 8 years |
Pro Tip: Use digital lockers like DigiLocker to store documents securely.
Does the calculator account for state-specific taxes like professional tax?
No, this calculator focuses on central income tax only. State-specific taxes like professional tax are not included. Here’s how they work:
- Professional Tax: Levied by state governments (e.g., ₹200/month in Karnataka, ₹2,500/year in Maharashtra)
- Deduction: Professional tax paid is deductible from salary income under Section 16(iii)
- State Variations: Rates and exemptions vary by state (some states like Delhi don’t levy it)
To calculate net take-home salary, subtract professional tax from the post-income-tax amount shown in our calculator.
